Understanding how the human body responds to unexpected force perturbations during quiet sitting is important to the science of motor behavior and the design of neuroprostheses for sitting posture. In this study, the performance characteristics of the neck and trunk in healthy individuals were assessed by measuring the kinematic responses to sudden, unexpected force perturbations applied to the thorax. Perturbations were applied in eight horizontal directions. It was hypothesized that displacement of the trunk, settling time and steady-state error would increase when the perturbation direction was diagonal (i.e., anterior-lateral or posterior-lateral) due to the increased complexity of asymmetrical muscle responses. Perturbation forces were applied manually. The neck and trunk responded in a synchronized manner in which all joints achieved peak displacement simultaneously then returned directly to equilibrium. Displacement in the direction of perturbation and perpendicular to the direction of perturbation were both significantly greater in response to diagonal perturbations (p < .001). The center of mass returned to equilibrium in 3.64 ± 1.42 s after the onset of perturbation. Our results suggest that the trunk sometimes behaves like an underdamped oscillator and is not controlled by simple stiffness when subjected to loads of approximately 200 N. The results of this study are intended to be used to develop a neuroprosthesis for artificial control of trunk stability in individuals with spinal cord injury. [ABSTRACT FROM AUTHOR]

Low hip and knee region bone mineral density (BMD) after spinal cord injury (SCI) results in an increased risk of lower extremity fragility fractures or sublesional osteoporosis (SLOP). There are currently no guidelines for the identification and treatment of SLOP among patients with chronic SCI. A paradigm for identification (medical screening, fracture risk, and bone mineral density assessment) of persons with SLOP who warrant treatment and selection of appropriate SLOP treatment(s) (lifestyle/nutrition modifications, bisphosphonate/rehabilitation therapies) is proposed. Content is based on the authors' opinions/expertise and available published and unpublished literature and is intended for use by rehabilitation professionals. [ABSTRACT FROM AUTHOR]

Study design:Prospective, observational cohort study.Objectives:This paper describes the rationale and methodology for the Study of Health and Activity in People with Spinal Cord Injury (SHAPE SCI). The study aims to (1) describe physical activity levels of people with different injury levels and completeness, (2) examine the relationship between physical activity, risk and/or presence of secondary health complications and risk of chronic disease, and (3) identify determinants of physical activity in the SCI population.Setting:Ontario, Canada.Methods:Seven hundred and twenty men and women who have incurred a traumatic SCI complete self-report measures of physical activity, physical activity determinants, secondary health problems and subjective well-being during a telephone interview. A representative subsample (n=81) participate in chronic disease risk factor testing for obesity, insulin resistance and coronary heart disease. Measures are taken at baseline, 6 and 18 months.Conclusion:SHAPE SCI will provide much-needed epidemiological information on physical activity patterns, determinants and health in people with SCI. This information will provide a foundation for the establishment of evidence-based physical activity guidelines and interventions tailored to the SCI community.Spinal Cord (2008) 46, 216-221; doi:10.1038/sj.sc.3102103; published online 24 July 2007.

Purpose. To examine the third version of the Spinal Cord Independence Measure (SCIM III) for reliability and validity in a multi-center cohort study. Method. Four hundred and twenty-five patients with spinal cord lesions from 13 spinal cord units in six countries from three continents were assessed with SCIM III and the Functional Independence measure (FIM) on admission to rehabilitation and before discharge. Results. Total agreement between raters was above 80% in most SCIM III tasks, and all kappa coefficients were statistically significant (P < 0.001). The coefficients of Pearson correlation between the paired raters were above 0.9, and intraclass correlation coefficients were above 0.94. Cronbach's [alpha] was above 0.7. The coefficient of Pearson correlation between FIM and SCIM III was 0.790 (P < 0.01). SCIM III was more responsive to changes than FIM in the subscales of Respiration and sphincter management and Mobility indoors and outdoors. Conclusions. The results support the reliability and validity of SCIM III in a multi-cultural setup. Despite several limitations of the study, the results indicate that SCIM III is an efficient measure for functional assessment of SCL patients and can be safely used for clinical and research trials, including international multi-center studies.

Background: There is a high incidence of erectile dysfunction after spinal cord injury. This can have a profound effect on quality of life. Treatment options for erectile dysfunction include sildenafil, intracavernous injections of papaverine/alprostadil (Caverject(R)), alprostadil/papaverine/phentolamine ('Triple Mix'), transurethral suppository (MUSE(R)), surgically implanted prosthetic device and vacuum erection devices. However, physical impairments and accessibility may preclude patient self-utilization of non-oral treatments. Methods: The costs and utilities of oral and non-oral erectile dysfunction treatments in a spinal cord injury population were examined in a cost-utility analysis conducted from a government payer perspective. Subjects with spinal cord injury ( n =59) reported health preferences using the standard gamble technique. Results: There was a higher health preference for oral therapy. The cost-effectiveness results indicated that sildenafil was the dominant economic strategy when compared with surgically implanted prosthetic devices, MUSE(R) and Caverject(R). The incremental cost-utility ratios comparing sildenafil with triple mix and vacuum erection devices favoured sildenafil, with ratios less than CAN$20,000 per quality adjusted life year gained. Conclusion: Based on this study, we conclude that sildenafil is a cost-effective treatment for erectile dysfunction in the spinal cord injury population. [ABSTRACT FROM AUTHOR]

Low bone mineral density (BMD) and osteoporosis are health concerns among older adults and individuals with physical, neurological, and/or mobility impairments. Detrimental changes in bone density and bone architecture occurring in these individuals may be due in part to the reduction/cessation of physical activity and the accompanying reduction of mechanical strain on bone. Changes in bone architecture predispose these individuals to fragility fractures during low-trauma events. Whole-body vibration (WBV) has been examined as an intervention for maintaining or improving bone mass among people with low BMD, because it may emulate the mechanical strains observed during normal daily activities. This article provides an overview of WBV including terminology, safety considerations, and a summary of the current literature; it is intended for rehabilitation healthcare providers considering WBV as a potential therapy for individuals with osteoporosis.

Background: Personal, social, and environmental factors may influence self-efficacy and social reintegration among people living with spinal cord injury or disease (SCI/D) in urban and rural areas. Novel data collection methods have the potential to characterize community participation (CP) in diverse settings., Objectives: The objectives were (1) to describe and compare self-reported community participation (Reintegration to Normal Living Index (RNLI) and Moorong Self-Efficacy Scale (MSES)) levels of individuals with SCI/D living in urban or rural Ontario, Canada; and (2) to determine the accuracy of an artificial intelligence (AI) optical mark recognition tool for extracting data from CP surveys conducted among participants after transitioning from inpatient rehabilitation to home and residing in the community., Methods: We partnered with SCI Ontario staff to collect MSES and RNLI survey data from adults with motor complete (e.g., AIS A-B) and incomplete (AIS C-D) SCI/D living in urban or rural Ontario, Canada, between January and October 2022. The Rurality Index of Ontario (RIO) from the postal code determined urban or rural residency. Optical mark recognition (OMR) software was used for survey data extraction. A Research Associate validated the extracted survey responses. Descriptive statistics, correlation analysis, and non-parametric statistics were used to describe the participants, their impairments, and their reported CP levels across urban and rural settings., Results: Eighty-five individuals with SCI/D (mean age 53.7 years, 36.5% female) completed the survey. Most of the participants resided in major urban areas (69.4%) and had traumatic injuries (64.7%). The mean total MSES score for Ontarians with SCI/D was 87.96 (95% confidence interval [CI]: 84.45, 91.47), while the mean total RNLI score for the same individuals was 75.61 (95% CI: 71.85, 79.37). Among the MSES domains, the lowest score was observed in response to sexual satisfaction (mean: 4.012, 95% CI: 3.527, 4.497), while the lowest RNLI domain item score was associated with the ability to travel out of town (mean: 5.965, 95% CI: 5.252, 6.678). Individuals with incomplete injuries in rural areas reported lower MSES and RNLI scores than those with complete motor injuries, whereas no significant differences were found in MSES and RNLI scores among urban residents based on impairment. These findings suggest that, depending on the environmental context (e.g., rural vs. urban areas), AIS categories may influence the perception of CP among people living with SCI/D. The OMR tool had 97.4% accuracy in extracting data from the surveys., Conclusions: The CP (MSES and RNLI) scores reported by individuals with SCI/D differ based on their living setting. In rural Ontario, individuals with greater functional ability reported lower CP than their counterparts living in urban settings. Although CP remains a challenge, the needs of individuals with motor incomplete SCI/D and heterogeneous levels of mobility residing in rural areas require exploration and targeted interventions. The OMR tool facilitates accurate data extraction from surveys across settings.

Background/objective: The purpose of this study was to investigate the impact of the COVID-19 pandemic on mortality rates in a community-dwelling spinal cord injury (SCI) population in Ontario., Methods: Using health administrative databases, monthly mortality rates were evaluated pre-pandemic, during the pandemic, and post-pandemic from March 2014 to May 2024. Data were stratified by sex, injury etiology, and mental health status. Group differences were evaluated using t -tests. Autoregressive integrated moving average (ARIMA) models evaluated the pandemic's impact on mortality rates., Results: A significant increase of 21.4% in mortality rates during the pandemic was found for the SCI cohort. With the exception of the traumatic group, all subgroups also experienced a significant increase in mortality rates (males: 13.9%, females: 31.9%, non-traumatic: 32.3%, mental health diagnoses: 19.6%, and mental health diagnoses: 29.4%). During the pandemic, females had a significantly higher mortality rate than males. The non-traumatic group had higher mortality rates than the traumatic group at all time periods. Individuals with mental health diagnoses had higher mortality rates than those without at the pre-pandemic and pandemic periods., Conclusions: The variation in mortality rates across groups highlights inequitable access to medical care in the SCI population, with further research and interventions needed.

Purpose: The R ehabilitation I nterventions for I ndividuals with a S pinal Cord Injury in the C ommunity (RIISC) team aimed to develop and evaluate innovative rehabilitation interventions to identify endocrine metabolic disease (EMD) risk, intending to reduce the frequency and severity of EMD related morbidity and mortality among adults living with chronic spinal cord injury or disease (SCI/D)., Materials and Methods: An interprovincial team from Ontario and Quebec reviewed available EMD literature and evidence syntheses and completed an inventory of health services, policies and practices in SCI/D care. The review outcomes were combined with expert opinion to create an EMD risk model to inform health service transformation., Results: EMD risk and mortality are highly prevalent among adults with chronic SCI/D. In stark contrast, few rehabilitation interventions target EMD outcomes. The modelled solution proposes: 1) abandoning single-disease paradigms and examining a holistic perspective of the individual's EMD risk, and 2) developing and disseminating practice-based research approaches in outpatient community settings., Conclusions: RIISC model adoption could accelerate EMD care optimization, and ultimately inform the design of large-scale longitudinal pragmatic trials likely to improve health outcomes. Linking the RIISC team activities to economic evaluations and policy deliverables will strengthen the relevance and impact among policymakers, health care providers and patients.

Persons with disabilities experience numerous barriers to healthcare access including vaccine accessibility. The purpose of this study was to determine COVID-19 vaccine uptake in the spinal cord injury and disease (SCI/D) population of Ontario and identify potential factors influencing C OVID-19 vaccine uptake. This was a retrospective closed-cohort study using administrative health data on individuals with SCI/D of traumatic and non-traumatic causes to examine the monthly number of COVID-19 vaccine doses received between December 2020 and December 2023. Logistic regression analysis was used to examine the potential association between socio-demographic, clinical, and neighbourhood characteristics with initial COVID-19 vaccine receipt and booster dose uptake. By the end of the observation period in December 2023, 82.9% received the full two-dose coverage and 65.6% received at least one additional booster dose in a cohort of 3574 individuals with SCI/D. SCI/D individuals showed a comparable COVID-19 vaccine uptake percentage to the general population. Sociodemographic, clinical, and neighbourhood characteristics were associated with COVID-19 vaccine uptake in the SCI/D population, including age, type of injury, number of comorbidities, mental health history, and neighbourhood characteristics such as income. Further investigation is necessary to determine the causation effects of these relationships with vaccine uptake to address health equity concerns.

Objective: Parkwood VIP4SCI platform is a virtual e-health solution adapted from a version created for Spinal Cord Injury Ontario (SCIO) that focused on self-management skill development for persons with spinal cord injury (SCI) transitioning between stages of care, in partnership with caregivers and clinicians. This evaluation of the platform informs the usability and feasibility of a model to facilitate service care aims postrehabilitation., Design: Participants: Inpatients and outpatients admitted to the SCI Rehabilitation Program (n = 31), and a mix of interdisciplinary clinicians on the Rehabilitation Team (n = 20). Caregivers participated at the discretion of the patient. Interventions: Inpatients were randomized into two groups (Platform or Standard Care (i.e., delayed access)). Outpatients were given access at enrollment. Pre-post assessments were completed using surveys, and platform analytics were collected. Weekly check-ins were introduced to increase engagement. Focus groups were held with a subset of participants near study completion., Results: VIP4SCI was viewed as usable and feasible. Platform satisfaction assessed on a -3 to +3 scale ranged from +0.9 to 2.5, demonstrating positive agreement. Self-efficacy related to self-management ranged from 5.4 to 7.6 out of 10. The educational resource hub was identified as the most beneficial feature. Lack of clinician uptake was a barrier to integration into day-to-day practice., Conclusions: Platform usage was low among all groups despite the perceived need for facilitating care coordination with consistent and intentional self-management programming. Despite the lack of uptake, partly due to challenges associated with the pandemic, conclusions on platform features and barriers to implementation will help to inform future programming., Competing Interests: The authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2024.)

Purpose: People with spinal cord injury (SCI) experience a considerable loss of bone after the injury. Lumbar spine (LS) bone mineral density (BMD) has been reported to be within the normal range, or even higher when assessed with DXA, in people with SCI; hence, it has been hypothesized that sources of error may spuriously increase LS BMD. The aim of this study was to describe the frequency of potential sources of error that may alter LS BMD measurement in a cohort of individuals with chronic SCI at baseline and over a 2-year period., Methods: We analyzed baseline and 2-year follow up DXA scans (Hologic Discovery QDR 4500, Hologic Inc., MA, USA) previously performed from a cohort of males and females with chronic SCI. Two physicians independently reviewed each scan, commented on whether the scan was appropriate for BMD analysis, should be re-analyzed, or be removed from the dataset, and reported on the presence of potential sources of error in LS BMD measurement., Results: We reviewed 115 lumbar spine DXA scans from 58 participants, and 107 (93.0 %) scans from 52 participants presented at least one potential source of error. At baseline, the average number of potential sources of error per scan was 5.5 ± 1.7 and 5.7 ± 1.5 according to rater 1 and rater 2, respectively. Follow-up scans presented an average of 5.6 ± 1.6 and 5.7 ± 1.4 potential sources of error according to rater 1 and rater 2, respectively. Facet sclerosis, osteophytes and difficulty in detecting bone edges were the most prevalent sources of error., Conclusion: The high frequency of potential sources of error is consistent with current recommendations against the use of LS BMD for fracture risk assessment in people with SCI., Competing Interests: Conflict of interest The authors declare no conflict of interest., (Copyright © 2024 The Author(s).

Introduction: The Consortium for Spinal Cord Medicine's inaugural Clinical Practice Guideline for Bone Health and Osteoporosis Management for Individuals with Spinal Cord Injury or Disease (CSCM-CPG) was published in 2022 for a clinician audience. The aim of this project was to develop a podcast series to ensure people with lived experience with Spinal Cord Injury or Disease (PLEX) understand the CSCM-CPG content and know how to act to reduce their fracture risk., Methods: The "Bare Bones Podcast Series" consists of nine episodes; one related to each CSCM-CPG chapter. The podcast content and the questions asked in each podcast were co-developed by PLEX partners (PLEX-P) and the project team. Two PLEX-P acted as co-hosts for the series. The invited speaker(s) were CSCM-CPG expert panel members who participated in an informal dialogue with the hosts. Each podcast closes with a specific action a listener can do to advance their bone health. The related Educational Action Planning Tool (EAT) handouts contain text and infographic information specific to each podcast episode and include key concepts and a specific actionable take-home message. Local PLEX reviewers (PLEX-R) were invited to review podcast episodes and EATs and provide their feedback through focus group participation or one-on-one (1:1) interviews. The project team revised the podcast episodes and the EATs based on feedback from the PLEX-R prior to releasing them online., Results: Nine podcast episodes and related EATs were designed and created collaboratively with 3 PLEX-P, 22 PLEX-R, 11 CSCM-CPG expert panel members, and the project team. The episodes were titled: "Introduction to the Bare Bones of Bone Health"; "Fracture 101"; "Blood Tests-a Window into You"; "I See Your Skeleton"; "Vitamin D for all, Calcium for Some"; "Get Moving and Loading"; "Pills or Poisons & Atomic Habits"; "Snap and Crack"; and "Directions for Research". The Bare Bones Podcast Series was shared through the project website., Conclusions: The podcasts will aid PLEX and their family caregivers to advocate for ongoing bone health assessments and to promote an ongoing dialogue with care team members regarding how to prevent fractures and fracture-related morbidity and mortality., Competing Interests: BC was the Panel Chair for the Consortium for Spinal Cord Medicine's Clinical Practice Guideline for Bone Health and Osteoporosis Management for Individuals with Spinal Cord Injury or Disease. BC is the Chair of the Canadian Spinal Cord Injury Rehabilitation Association and a Board member of the Ontario SPOR Support Unit Board of Directors and a former member of the Osteoporosis Canada Scientific Advisory Committee. BC receives support from the UHN Foundation as the Cope Family Chair in Spinal Cord Injury Health Systems Innovation.

Study Design: Descriptive repeated-cross sectional retrospective longitudinal cohort study., Objective: To investigate the impact of the COVID-19 pandemic on homecare services in individuals with traumatic or non-traumatic Spinal Cord Injury (SCI)., Setting: Health administrative database in Ontario, Canada., Methods: A repeated cross-sectional study using linked health administrative databases from March 2015 to June 2022. Monthly homecare utilization was assessed in 3381 adults with SCI using Autoregressive Integrated Moving Average (ARIMA) models., Results: Compared to pre-pandemic levels, between March 2020 to June 2022, the traumatic group experienced a decrease in personal and/or homemaking services, as well as an increase in nursing visits from April 2020-March 2022 and June 2022. Case management increased at various times for the traumatic group, however therapies decreased in May 2020 only. The non-traumatic group experienced a decrease in personal and/or homemaking services in July 2020, as well as an increase in nursing visits from March 2020 to February 2021 and sporadically throughout 2020. Case management also increased at certain points for the non-traumatic group, but therapies decreased in April 2020, July 2020, and September 2021., Conclusion: The traumatic group had decreases in personal and/or homemaking services. Both groups had increases in nursing services, increases in case management, and minimal decreases in therapies at varying times during the pandemic. Investigation is warranted to understand the root cause of these changes, and if they resulted in adverse outcomes., (© 2024.

Background: Despite preventability, 20-50% of patients with acute spinal cord injury/disease (SCI/D) develop hospital-acquired pressure injuries (PIs). The Spinal Cord Injury Implementation and Evaluation Quality Care Consortium (SCI IEQCC) aimed to mitigate PI risk through patient-reported daily skin checks alongside usual care., Methods: This quality improvement initiative utilized an interrupted time series design, encompassing adults ≥ 18 years admitted for inpatient rehabilitation across five Ontario sites from 2020 to 2023. Patient demographics, etiology, and impairment data were obtained from a national registry, while participating sites gathered data on PI onset, location, and severity. Run charts depicted temporal trends, and statistical analyses, including chi-square and logistic regression, compared patients with and without PIs., Results: Data from 1767 discharged SCI/D patients revealed that 26% had ≥1 PI, with 59% being prevalent and 41% incident. Most severe PIs (stages III and IV and unstageable) were acquired prior to admission. Process indicator fidelity was reasonable at 68%. Patients with PIs experienced longer hospital stays, lower Functional Independence Measure (FIM) changes, and FIM efficiency during rehabilitation., Conclusions: PI prevalence is increasing, particularly sacral injuries at admission, while incident cases have decreased since 2021 due to regular skin checks. This trend calls for proactive health system interventions to reduce costs and improve patient outcomes.

Background: Exoskeletons are increasingly applied during overground gait and balance rehabilitation following neurological impairment, although optimal parameters for specific indications are yet to be established., Objective: This systematic review aimed to identify dose and dosage of exoskeleton-based therapy protocols for overground locomotor training in spinal cord injury/disease., Methods: A systematic review was conducted in accordance with the Preferred Reporting Items Systematic Reviews and Meta-Analyses guidelines. A literature search was performed using the CINAHL Complete, Embase, Emcare Nursing, Medline ALL, and Web of Science databases. Studies in adults with subacute and/or chronic spinal cord injury/disease were included if they reported (1) dose (e.g., single session duration and total number of sessions) and dosage (e.g., frequency of sessions/week and total duration of intervention) parameters, and (2) at least one gait and/or balance outcome measure., Results: Of 2,108 studies identified, after removing duplicates and filtering for inclusion, 19 were selected and dose, dosage and efficacy were abstracted. Data revealed a great heterogeneity in dose, dosage, and indications, with overall recommendation of 60-min sessions delivered 3 times a week, for 9 weeks in 27 sessions. Specific protocols were also identified for functional restoration (60-min, 3 times a week, for 8 weeks/24 sessions) and cardiorespiratory rehabilitation (60-min, 3 times a week, for 12 weeks/36 sessions)., Conclusion: This review provides evidence-based best practice recommendations for overground exoskeleton training among individuals with spinal cord injury/disease based on individual therapeutic goals - functional restoration or cardiorespiratory rehabilitation. There is a need for structured exoskeleton clinical translation studies based on standardized methods and common therapeutic outcomes., (© 2024. The Author(s).)

Background: Individuals with spinal cord injuries or disease (SCI/D) require frequent healthcare services. The COVID-19 pandemic may have impacted healthcare. Furthermore, due to secondary health conditions and comorbidities persons with SCI/D are at increased risk of experiencing severe symptoms or outcomes if infected with the COVID-19 virus. It is unclear to what extent research has investigated the pandemic and virus impacts on the SCI/D population., Objective: To identify and summarize what is reported in the literature on the impact the COVID-19 virus and pandemic had on healthcare, health outcomes, and experiences in the adult SCI/D population., Methods: Electronic databases and grey literature were searched for articles that included an adult population with a SCI/D and investigated the impact the COVID-19 virus and pandemic had on healthcare-related outcomes and experiences. Articles were double screened, and data were extracted, and synthesized to provide a descriptive summary of the findings., Results: Twenty-four studies were included in this review with eight qualitative, fifteen quantitative, and one mixed methods study. Sixteen studies investigated healthcare utilization/access; nine investigated care delivery, nine investigated patient outcomes, and eight investigated patient experiences, with multiple studies spanning different categories of investigation. The pandemic was detrimental to healthcare utilization, access, and outcomes, but no studies quantified these changes. Virtual care was well-received by the SCI/D population to maintain continuity of care. The SCI/D population had issues with maintaining caregiving support. It was unclear if the COVID-19 virus infection impacted individuals with SCI/D differently than the general population., Conclusions: This scoping review found the pandemic negatively impacted multiple aspects of healthcare in individuals with SCI/D, however further investigation on health outcomes is required. More research, particularly large-scale quantitative studies, investigating healthcare access, utilization, and delivery, as well as patient outcomes and experiences is needed to improve care in the SCI/D population post-pandemic onset., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Senthinathan et al.

Study Design: A retrospective cross-sectional study., Objective: To identify who prescribes outpatient antibiotics among a primary care spinal cord injury (SCI) cohort., Setting: ICES databases in Ontario, Canada., Methods: A cohort of individuals with SCI were retrospectively identified using a tested-algorithm and chart reviews in a primary care electronic medical records database. The cohort was linked to a drug dispensing database to obtain outpatient antibiotic prescribing information, and prescriber details were obtained from a physician database., Results: Final cohort included three hundred and twenty individuals with SCI. The average annual number of antibiotic courses dispensed for the SCI cohort was 2.0 ± 6.2. For dispensed antibiotics, 58.9% were prescribed by rostered-primary care practice physicians, compared to 17.9% by emergency and non-rostered primary care physicians, 17.4% by specialists and 6.1% by non-physician prescribers. Those who lived in urban areas and rural areas, compared to those who lived in suburban areas, were more likely to receive antibiotics from emergency and non-rostered primary care physicians than from rostered-primary care practice physicians., Conclusion: Although individuals with SCI received outpatient antibiotic prescriptions from multiple sources, physicians from an individual's rostered-primary care practice were the main antibiotic prescribers. As such, interventions to optimize antibiotics use in the SCI population should target the primary care practice., (© 2024.

Aim: This study aimed to (1) describe the use of the Standing and Walking Assessment Tool (SWAT) among individuals with non-traumatic spinal cord injury or disease (NT-SCI/D); (2) evaluate the convergent validity of SWAT for use among inpatients with NT-SCI/D; (3) describe SWAT responsiveness; and (4) explore the relationship between hours of walking therapy and SWAT change., Methods: A quality improvement project was conducted at the University Health Network between 2019 and 2022. Participants' demographics and impairments data, rehabilitation length of stay, and FIM scores were obtained from the National Rehabilitation Reporting System. The walking measure data were collected by therapists as part of routine practice. Hours of part- or whole-gait practice were abstracted from medical records. To determine convergent validity, Spearman's correlation coefficients were calculated between SWAT stages (admission and discharge) and the walking measures. The change in SWAT levels was calculated to determine responsiveness. Spearman's correlation coefficient was calculated between SWAT change and hours of walking therapy., Results: Among adult NT-SCI/D participants with potential walking capacity (SWAT≥1B), the majority were classified as American Spinal Injury Association (ASIA) Impairment Scale D (AIS D) at admission. The SWAT category of 1C ( N  = 100, 18%) was the most frequent at admission. The most frequent SWAT stage at discharge was 3C among participants with NT-SCI/D, with positive conversions in SWAT stages from admission to discharge ( N  = 276, 33%). The mean change in SWAT score was 3 for participants with T-SCI and NT-SCI/D. Moderate correlations between SWAT stages and walking measures were observed. The correlation of hours of gait therapy with the SWAT change (admission to discharge) was 0.44 ( p  < 0001)., Conclusion: The SWAT has sufficient convergent validity and responsiveness for describing standing and walking recovery and communicating/monitoring rehabilitation progress among patients with NT-SCI/D., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Alavinia, Farahani, Musselman, Plourde, Omidvar, Verrier, Aliabadi and Craven.)

Study Design: A retrospective longitudinal cohort time-series analysis study., Objectives: To examine healthcare utilization and delivery during the COVID-19 pandemic in individuals with spinal cord injury/dysfunction (SCI/D)., Setting: Health administrative database in Ontario, Canada., Methods: In 5754 individuals with SCI/D diagnosed from 2004-2014 and living in the community, healthcare utilization (physician visits, primary care visits, specialist visits, urologist visits, physiatrist visits, emergency department (ED) visits, and hospital admissions) and delivery (total, in-person, virtual) were determined at the (1) pre-pandemic period (March 2015 to February 2020), (2) initial pandemic onset period (March 2020-May 2020), and (3) pandemic period (June 2020 to March 2022). Autoregressive integrated moving average (ARIMA) modelling was conducted to determine the impact of the pandemic on monthly healthcare utilization and delivery., Results: The initial pandemic onset period had a significant reduction of 24% in physicians (p = 0.0081), 35% in specialists (p < 0.0001), and 30% in urologist (p < 0.0001) visits, compared to pre-pandemic levels, with a partial recovery as the pandemic progressed. In April 2020, compared to the pre-pandemic period, a significant increase (p < 0.0001) in virtual visits for physicians, specialists, urologists, and primary care was found. The initial pandemic onset period had a 58% decrease in hospital admissions (p = 0.0011), compared to the pre-pandemic period., Conclusion: Healthcare utilization dropped in the initial pandemic onset period as physicians, specialists, and urologists, as well as hospitalization visits decreased significantly (p < 0.05) versus pre-pandemic levels. Virtual visit increases compensated for in-person visit decreases as the pandemic progressed to allow for total visits to partially recover., (© 2023.

Background: Assessment of aerobic exercise (AE) and lipid profiles among individuals with spinal cord injury or disease (SCI/D) is critical for cardiometabolic disease (CMD) risk estimation., Objectives: To utilize an artificial intelligence (AI) tool for extracting indicator data and education tools to enable routine CMD indicator data collection in inpatient/outpatient settings, and to describe and evaluate the recall of AE levels and lipid profile assessment completion rates across care settings among adults with subacute and chronic SCI/D., Methods: A cross-sectional convenience sample of patients affiliated with University Health Network's SCI/D rehabilitation program and outpatients affiliated with SCI Ontario participated. The SCI-HIGH CMD intermediary outcome (IO) and final outcome (FO) indicator surveys were administered, using an AI tool to extract responses. Practice gaps were prospectively identified, and implementation tools were created to address gaps. Univariate and bivariate descriptive analyses were used., Results: The AI tool had <2% error rate for data extraction. Adults with SCI/D ( n = 251; 124 IO, mean age 61; 127 FO, mean age 55; p = .004) completed the surveys. Fourteen percent of inpatients versus 48% of outpatients reported being taught AE. Fifteen percent of inpatients and 51% of outpatients recalled a lipid assessment ( p < .01). Algorithms and education tools were developed to address identified knowledge gaps in patient AE and lipid assessments., Conclusion: Compelling CMD health service gaps warrant immediate attention to achieve AE and lipid assessment guideline adherence. AI indicator extraction paired with implementation tools may facilitate indicator deployment and modify CMD risk., (© 2023 American Spinal Injury Association.)

Background: Individuals with a spinal cord injury (SCI) are considered higher users of antibiotics. However, to date there have been no detailed studies investigating outpatient antibiotic use in this population., Objectives: (1) To describe primary care antibiotic prescribing patterns in adults with SCI rostered to a primary care physician (PCP), and (2) to identify patient or PCP factors associated with number of antibiotics prescribed and antibiotic prescription duration., Methods: A retrospective cohort study using linked health administrative and electronic medical records (EMR) databases from January 1, 2013 to December 31, 2015 among 432 adults with SCI in Ontario, Canada. Negative binomial regression analyses were conducted to identify patient or physician factors associated with number of antibiotics prescribed and prescription duration., Results: During the study period, 61.1% of the SCI cohort received an antibiotic prescription from their PCP. There were 59.8% of prescriptions for urinary tract infections (UTI) and 24.6% of prescriptions for fluoroquinolones. Regression analysis found catheter use was associated with increased number of antibiotics prescribed (relative risk [RR] = 3.1; 95% CI, 2.3-4.1; p < .001) and late career PCPs, compared to early-career PCPs, prescribed a significantly longer duration (RR = 1.8; 95% CI, 1.1-3.1; p = .02)., Conclusion: UTIs were the number one prescription indication, and fluoroquinolones were the most prescribed antibiotic. Catheter use was associated with number of antibiotics, and PCP's years of practice was associated with duration. The study provided important information about primary care antibiotic prescribing in the SCI population and found that not all individuals received frequent antibiotics prescriptions., Competing Interests: Conflicts of Interest The authors declare no conflicts of interest., (© 2023 American Spinal Injury Association.)

Objectives: To develop SCI-FX, a risk score to estimate 5-year lower extremity fragility fracture risk among patients living with chronic spinal cord injury (cSCI)., Methods: Adults with traumatic cSCI ( n = 90) participated in a 2-year prospective longitudinal cohort study describing bone mineral density (BMD) change and fracture incidence conducted at the Lyndhurst Centre (University Health Network), University of Waterloo, and Physical Disability Rehabilitation Institute of Québec City. Prior publication and clinical intuition were used to identify fragility fracture risk factors including prior fragility fracture, years post-injury, motor complete injury (AIS A/B), benzodiazepine use, opioid use, and parental osteoporosis. We conducted bivariate analyses to identify variables associated with fracture. Multiple logistic regressions were performed using fragility fracture incidence as the dependent variable and all variables from the univariate analyses with a highly liberal p value at 0.2. Using the odds ratios (ORs) from the multiple logistic regression model, a point system for fragility fracture risk score was developed, and the odds of fracture for each point was estimated., Results: All initial variables, with the exception of benzodiazepine exposure, were included in the final model., Conclusion: We identified a simple preliminary model for clinicians to estimate 5-year fracture risk among patients with cSCI based on their total score., Competing Interests: Conflicts of Interest Dr. Craven reports grants from the Canadian Institutes of Health Research (CIHR), Ontario Ministry of Health, Paralyzed Veterans of America, Craig H.

Background: The prevention of lower extremity fractures and fracture-related morbidity and mortality is a critical component of health services for adults living with chronic spinal cord injury (SCI)., Methods: Established best practices and guideline recommendations are articulated in recent international consensus documents from the International Society of Clinical Densitometry, the Paralyzed Veterans of America Consortium for Spinal Cord Medicine and the Orthopedic Trauma Association., Results: This review is a synthesis of the aforementioned consensus documents, which highlight the pathophysiology of lower extremity bone mineral density (BMD) decline after acute SCI. The role and actions treating clinicians should take to screen, diagnose and initiate the appropriate treatment of established low bone mass/osteoporosis of the hip, distal femur or proximal tibia regions associated with moderate or high fracture risk or diagnose and manage a lower extremity fracture among adults with chronic SCI are articulated. Guidance regarding the prescription of dietary calcium, vitamin D supplements, rehabilitation interventions (passive standing, functional electrical stimulation (FES) or neuromuscular electrical stimulation (NMES)) to modify bone mass and/or anti-resorptive drug therapy (Alendronate, Denosumab, or Zoledronic Acid) is provided. In the event of lower extremity fracture, the need for timely orthopedic consultation for fracture diagnosis and interprofessional care following definitive fracture management to prevent health complications (venous thromboembolism, pressure injury, and autonomic dysreflexia) and rehabilitation interventions to return the individual to his/her pre-fracture functional abilities is emphasized., Conclusions: Interprofessional care teams should use recent consensus publications to drive sustained practice change to mitigate fracture incidence and fracture-related morbidity and mortality among adults with chronic SCI.

Study Design: A retrospective cohort study., Objectives: To describe antibiotic prescribing and urine culture testing patterns for urinary tract infections (UTIs) in a primary care Spinal Cord Injury (SCI) cohort., Setting: A primary care electronic medical records (EMR) database in Ontario., Methods: Using linked EMR health administrative databases to identify urine culture and antibiotic prescriptions ordered in primary care for 432 individuals with SCI from January 1, 2013 to December 31, 2015. Descriptive statistics were conducted to describe the SCI cohort, and physicians. Regression analyses were conducted to determine patient and physician factors associated with conducting a urine culture and class of antibiotic prescription., Results: The average annual number of antibiotic prescriptions for UTI for the SCI cohort during study period was 1.9. Urine cultures were conducted for 58.1% of antibiotic prescriptions. Fluroquinolones and nitrofurantoin were the most frequently prescribed antibiotics. Male physicians and international medical graduates were more likely to prescribe fluroquinolones than nitrofurantoin for UTIs. Early-career physicians were more likely to order a urine culture when prescribing an antibiotic. No patient characteristics were associated with obtaining a urine culture or antibiotic class prescription., Conclusion: Nearly 60% of antibiotic prescriptions for UTIs in the SCI population were associated with a urine culture. Only physician characteristics, not patient characteristics, were associated with whether or not a urine culture was conducted, and the class of antibiotic prescribed. Future research should aim to further understand physician factors with antibiotic prescribing and urine culture testing for UTIs in the SCI population., (© 2023.

The objective of this study was to explore the experiences and perspectives of individuals with chronic health conditions who had an adverse event (AE) as a result of resistance training (RT). We conducted web conference or telephone-based one-on-one semi-structured interviews with 12 participants with chronic health conditions who had an AE as a result of RT. Interview data were analyzed using the thematic framework method. Six themes were identified: (1) personal experiences with aging influence perceptions of RT; (2) physical and emotional consequences of AEs limit activities and define future RT participation; (3) injury recovery defines the severity of AE; (4) health conditions influence the perceived risks and benefits of participating in RT; (5) RT setting and trained supervision influence exercise behaviors and risk perceptions; and (6) experiencing a previous AE influences future exercise behavior. Despite participant awareness of the value and benefits of RT in both the context of aging and chronic health conditions, there is concern about experiencing exercise-related AEs. The perceived risks of RT influenced the participants' decision to engage or return to RT. Consequently, to promote RT participation, the risks, not just the benefits, should be properly reported in future studies, translated, and disseminated to the public. Novelty: -To increase the quality of published research with respect to AE reporting in RT studies. -Health care providers and people with common health conditions will be able to make evidence-based decisions as to whether the benefits of RT truly outweigh the risks., Competing Interests: The authors declare there are no competing interests.

Purpose: In this article, we illustrate use of a systematic approach to rating videofluoroscopic swallowing studies (VFSS), the Analysis of Swallowing Physiology: Events, Kinematics and Timing (ASPEKT) method. The method is applied to a clinical case series of individuals with a history of traumatic spinal cord injury (tSCI) requiring surgical intervention using a posterior approach. Previous studies suggest that swallowing is highly variable in this population given heterogeneity in mechanisms, location and extent of injury, and in surgical management approaches., Method: The case series involved 6 individuals who were at least 1 month postsurgery for management of tSCI. Participants completed a VFSS using a standardized bolus protocol. Each VFSS was blindly rated in duplicate using the ASPEKT method and compared with published reference values., Results: The analysis revealed considerable heterogeneity across this clinical sample. Penetration-aspiration scale scores of 3 or higher were not observed in this cohort. Of note, patterns of impairment did emerge, suggesting there are some commonalities across profiles in this population, including the presence of residue associated with poor pharyngeal constriction, reduced upper esophageal opening diameter, and short upper esophageal sphincter opening duration., Conclusions: Although the participants in this clinical sample shared a history of tSCI requiring surgical intervention using a posterior approach, there was great heterogeneity in swallowing profile. Using a systematic method to identify atypical swallowing parameters can guide clinical decision making for determining rehabilitative targets and measuring swallowing outcomes.

Background: Serum alkaline phosphatase (ALP) is measured as an indicator of bone or liver disease. Bone-specific alkaline phosphatase (B-ALP) is an isoform of ALP found in the bone tissue which can predict fractures and heterotopic ossification., Objective: The aim of this scoping review was to explore the current use of ALP and B-ALP in studies using humans or animal models of SCI, and to identify ways to advance future research using ALP and B-ALP as a bone marker after SCI., Results: HUMAN STUDIES: 42 studies were included. The evidence regarding changes or differences in ALP levels in individuals with SCI compared to controls is conflicting. For example, a negative correlation between B-ALP and total femur BMD was observed in only one of three studies examining the association. B-ALP seemed to increase after administration of teriparatide, and to decrease after treatment with denosumab. The effects of exercise on ALP and B-ALP levels are heterogeneous and depend on the type of exercise performed. ANIMAL STUDIES: 11 studies were included. There is uncertainty regarding the response of ALP or B-ALP levels after SCI; levels increased after some interventions, including vibration protocols, curcumin supplementation, cycles in electromagnetic field or hyperbaric chamber. Calcitonin or bisphosphonate administration did not affect ALP levels., Conclusion: Researchers are encouraged to measure the bone-specific isoform of ALP rather than total ALP in future studies in humans of animal models of SCI.

Context: Endocrine-metabolic disease (EMD) is associated with functional disability, social isolation, hospitalization and even death in individuals living with a chronic spinal cord injury (SCI). There is currently very low-quality evidence that rehabilitation interventions can reduce EMD risk during chronic SCI. Non-randomized trials and alternative study designs are excluded from traditional knowledge synthesis., Objective: To characterize evidence from level 3-4 studies evaluating rehabilitation interventions for their effectiveness to improve EMD risk in community-dwelling adults with chronic SCI., Methods: Systematic searches of MEDLINE PubMed, EMBASE Ovid, CINAHL, Cochrane Database of Systematic Reviews, and PsychInfo were completed. All longitudinal trials, prospective cohort, case-control studies, and case series evaluating the effectiveness of rehabilitation/therapeutic interventions to modify/associate with EMD outcomes in adults with chronic SCI were eligible. Two authors independently selected studies and abstracted data. Mean changes from baseline were reported for EMD outcomes. The Downs and Black Checklist was used to rate evidence quality., Results: Of 489 articles identified, 44 articles ( N  = 842) were eligible for inclusion. Individual studies reported statistically significant effects of electrical stimulation-assisted training on lower-extremity bone outcomes, and the combined effects of exercise and dietary interventions to improve body composition and cardiometabolic biomarkers (lipid profiles, glucose regulation). In contrast, there were also reports of no clinically important changes in EMD outcomes, suggesting lower quality evidence (study bias, inconsistent findings)., Conclusion: Longitudinal multicentre pragmatic studies involving longer-term exercise and dietary intervention and follow-up periods are needed to fully understand the impact of these rehabilitation approaches to mitigate EMD risk. Our broad evaluation of prospective cohort and case-control studies provides new perspectives on alternative study designs, a multi-impairment paradigm approach of studying EMD outcomes, and knowledge gaps related to SCI rehabilitation.

Objective: To obtain expert consensus on the parameters and etiologic conditions required to retrospectively identify cases of non-traumatic spinal cord injury (NTSCI) in health administrative and electronic medical record (EMR) databases based on the rating of clinical vignettes., Design: A modified Delphi process included 2 survey rounds and 1 remote consensus panel. The surveys required the rating of clinical vignettes, developed after chart reviews and expert consultation. Experts who participated in survey rounds were invited to participate in the Delphi Consensus Panel., Setting: An international collaboration using an online meeting platform., Participants: Thirty-one expert physicians and/or clinical researchers in the field of spinal cord injury (SCI)., Main Outcome Measure(s): Agreement on clinical vignettes as NTSCI. Parameters to classify cases of NTSCI in health administrative and EMR databases., Results: In health administrative and EMR databases, cauda equina syndromes should be considered SCI and classified as a NTSCI or TSCI based on the mechanism of injury. A traumatic event needs to be listed for injury to be considered TSCI. To be classified as NTSCI, neurologic sufficient impairments (motor, sensory, bowel, and bladder) are required, in addition to an etiology. It is possible to have both a NTSCI and a TSCI, as well as a recovered NTSCI. If information is unavailable or missing in health administrative and EMR databases, the case may be listed as "unclassifiable" depending on the purpose of the research study., Conclusion: The Delphi panel provided guidelines to appropriately classify cases of NTSCI in health administrative and EMR databases., (Copyright © 2022 American Congress of Rehabilitation Medicine.

Patients with Duchenne muscular dystrophy (DMD) have a high fracture burden due to progressive myopathy and steroid-induced osteoporosis. This study in males with DMD showed that markers of systemic glucocorticoid exposure including shorter stature, greater bone age delay, and lower lumbar spine bone mineral density were associated with spine fragility., Introduction: Fragility  fractures are frequent in DMD. The purpose of this study was to identify clinical factors associated with prevalent vertebral fractures (VF) in boys, teens/young adults with Duchenne muscular dystrophy (DMD)., Methods: This was a cross-sectional study of males aged 4-25 years with DMD. VF were evaluated using the modified Genant semi-quantitative method on T4-L4 lateral spine radiographs. Areal bone mineral density (aBMD) was measured at the lumbar spine (LS) and used to estimate volumetric BMD (vBMD). Clinical factors were analyzed for their association with the Spinal Deformity Index (SDI, the sum of the Genant grades)., Results: Sixty participants were enrolled (mean age 11.5 years, range 5.4-19.5). Nineteen participants (32%) had a total of 67 VF; 23/67 VF (34%) were moderate or severe. Participants with VF were shorter (mean height Z-score ± standard deviation: - 3.1 ± 1.4 vs. - 1.8 ± 1.4, p = 0.001), had longer glucocorticoid exposure (mean duration 6.0 ± 3.3 vs. 3.9 ± 3.3 years, p = 0.027), greater bone age (BA) delay (mean BA to chronological age difference - 3.2 ± 3.4 vs. - 1.3 ± 1.2 years, p = 0.035), and lower LSaBMD Z-scores (mean - 3.0 ± 1.0 vs. - 2.2 ± 1.2, p = 0.023). There was no difference in LSvBMD Z-scores. Multivariable Poisson regression showed that every 0.1 mg/kg/day increment in average glucocorticoid daily dose was associated with a 1.4-fold SDI increase (95% confidence interval: 1.1-1.7, p = 0.013). Greater BA delay (p < 0.001), higher weight Z-score (p = 0.004), decreased height Z-score (p = 0.025), and lower LSvBMD Z-score (p = 0.025) were also associated with SDI increase., Conclusion: Readily measurable clinical variables were associated with prevalent VF in males with glucocorticoid-treated DMD. These variables may be useful to identify candidates for primary osteoporosis prevention after glucocorticoid initiation., (© 2022.

Egocentric video has recently emerged as a potential solution for monitoring hand function in individuals living with tetraplegia in the community, especially for its ability to detect functional use in the home environment. The aim of this study was to develop and validate a wearable vision-based system for measuring hand use in the home among individuals living with tetraplegia. Several deep learning algorithms for detecting functional hand-object interactions were developed and compared. The most accurate algorithm was used to extract measures of hand function from 65 h of unscripted video recorded at home by 20 participants with tetraplegia. These measures were: the percentage of interaction time over total recording time (Perc); the average duration of individual interactions (Dur); and the number of interactions per hour (Num). To demonstrate the clinical validity of the technology, egocentric measures were correlated with validated clinical assessments of hand function and independence (Graded Redefined Assessment of Strength, Sensibility and Prehension [GRASSP], Upper Extremity Motor Score [UEMS], and Spinal Cord Independent Measure [SCIM]). Hand-object interactions were automatically detected with a median F1-score of 0.80 (0.67-0.87). Our results demonstrated that higher UEMS and better prehension were related to greater time spent interacting, whereas higher SCIM and better hand sensation resulted in a higher number of interactions performed during the egocentric video recordings. For the first time, measures of hand function automatically estimated in an unconstrained environment in individuals with tetraplegia have been validated against internationally accepted measures of hand function. Future work will necessitate a formal evaluation of the reliability and responsiveness of the egocentric-based performance measures for hand use.

Objectives: This scoping review was undertaken to synthetize and appraise the literature on the potential mechanisms of action of functional electrical stimulation therapy in combination with task-specific training (FEST + TST) in the rehabilitation following stroke, spinal cord injury, traumatic brain injury, or multiple sclerosis., Materials and Methods: The literature search was performed using multiple databases (including APA, PsycInfo, Medline, PubMed, EMBASE, CCRCT, and Cochrane Database of Systematic Reviews) from 1946 to June 2020. The literature search used the following terms: (spinal cord injury, paraplegia, tetraplegia, quadriplegia, stroke, multiple sclerosis, traumatic brain injury, or acquired brain injury) AND (functional electrical stimulation or FES). The search included clinical and preclinical studies without limits to language., Results: Of the 8209 titles retrieved from the primary search, 57 publications fulfilled the inclusion and exclusion criteria for this scoping review. While most publications were clinical studies (n = 50), there were only seven preclinical studies using animal models. The results of this review suggest that FEST + TST can result in multiple effects on different elements from the muscle to the cerebral cortex. However, most studies were focused on the muscle changes after FEST + TST., Conclusions: The results of this scoping review suggest that FEST + TST can result in multiple effects on different elements of the neuromuscular system, while most research studies were focused on the muscle changes after FEST + TST. Despite the efficacy of the FEST + TST in the neurorehabilitation after CNS injury or disease, the results of this review underline an important knowledge gap with regards to the actual mechanism of action of FEST + TST., (Copyright © 2022 International Neuromodulation Society.

The objectives of our study were to understand researchers' current practices and perspectives on adverse event (AE) reporting in clinical trials of resistance training (RT) and to identify barriers and facilitators of AE reporting. We conducted web conference or telephone-based one-on-one semistructured interviews with 14 researchers who have published RT studies. We audio-recorded and transcribed the interviews and analyzed the data using the thematic framework method. Four themes were identified: (1) researchers lack guidance and/or motivation for rigorous AE reporting; (2) researchers who undertake AE reporting educate and value participants, use trained personnel, and implement standardized guidelines; (3) suboptimal implementation of existing AE reporting standards and the perception that available guidelines do not apply to exercise trials; and (4) acceptability and feasibility of an exercise-specific guide for AE reporting depend on its content and format. In conclusion, AE reporting methods in the field of exercise science do not align with best practice. Strategies to reduce inconsistent and suboptimal AE reporting in RT trials are urgently needed and could be based on the barriers and facilitators identified in this study.

Purpose: To advance the understanding of perceived social isolation among persons with spinal cord injury (SCI), the objectives of the present study were to explore: (1) experiences of perceived social isolation and (2) factors that contribute to perceived social isolation., Methods: Interpretive description qualitative methodology was used to conduct semi-structured interviews with 30 individuals with SCI from across Ontario (Canada) from November 2016 to August 2017. Data were analyzed using thematic analysis., Results: Participants identified disruption to social networks that seemed to impact perceived social isolation. Five major themes were identified: (1) impact on structure and frequency of social network; (2) importance of feeling heard; (3) importance of employment, hobbies, and sports; (4) need to improve physical accessibility and built environment; and (5) individual characteristics. Changes in quality of social networks, rather than size, contributed to greater feelings of perceived social isolation. The built environment, maintenance of employment, hobbies, and sports, social media, and technology use, as well as individual traits, were also found to impact perceived social isolation., Conclusion: Future research should focus on the development of programs to help maintain or improve social network quality for persons with SCI to minimize the impact of perceived social isolation.IMPLICATIONS FOR REHABILITATIONPerceived social isolation, resulting from physical and environmental barriers, is a challenge that is faced by many individuals who are living in the community with a spinal cord injury (SCI).Rehabilitation and community programs should utilize an individualized approach to find solutions to challenges faced by this population to prevent the effects of perceived social isolation.Education on how to adapt to changes in social network, together with the provision of access to peer-to-peer support groups, and SCI specific return to work or leisure programs, is recommended as an essential component of rehabilitation.

Context: There has been no known research investigating the association between leisure time physical activity (LTPA), loneliness, and life satisfaction among people with spinal cord injury or dysfunction (SCI/D). The relationship between these constructs is worthy of consideration given the positive health impacts of LTPA, the negative health impacts of loneliness, and heightened negative effects of loneliness on life satisfaction for individuals with SCI/D. Objectives: To examine the relationship between LTPA and loneliness, and examine loneliness as a possible mediator of the relationship between LTPA and life satisfaction among individuals with SCI/D. Design and Participants: Community dwelling individuals with SCI/D ( N  = 170) participated in a telephone-based survey as part of a larger project. Measures: LTPA (i.e. The Leisure Time Physical Activity Questionnaire-SCI, UCLA Loneliness Scale-3, and the Life Satisfaction Questionnaire-11 were administered to the participants. Results: Significant bivariate relationships were observed between LTPA and life satisfaction ( r  = .18, P   = .02), LTPA and loneliness ( r  = -.15, P   = .045), and loneliness and life satisfaction ( r  = -.69, P   < .001). Mediation analyses suggest that loneliness significantly mediated the relationship between LTPA and life satisfaction (indirect effect = .003, 95% bootstrap CI = .0004 to .0062, CSI = .113). Conclusion: This was the first study to show evidence of a negative association between LTPA and loneliness among people with SCI/D, and to establish a conceptual model for understanding the potential mediating role of loneliness in the relationship between LTPA and life satisfaction among people with SCI/D.

Background: Simple visualizations in health research data, such as scatter plots, heat maps, and bar charts, typically present relationships between 2 variables. Interactive visualization methods allow for multiple related facets such as numerous risk factors to be studied simultaneously, leading to data insights through exploring trends and patterns from complex big health care data. The technique presents a powerful tool that can be used in combination with statistical analysis for knowledge discovery, hypothesis generation and testing, and decision support., Objective: The primary objective of this scoping review is to describe and summarize the evidence of interactive visualization applications, methods, and tools being used in population health and health services research (HSR) and their subdomains in the last 15 years, from January 1, 2005, to March 30, 2019. Our secondary objective is to describe the use cases, metrics, frameworks used, settings, target audience, goals, and co-design of applications., Methods: We adapted standard scoping review guidelines with a peer-reviewed search strategy: 2 independent researchers at each stage of screening and abstraction, with a third independent researcher to arbitrate conflicts and validate findings. A comprehensive abstraction platform was built to capture the data from diverse bodies of literature, primarily from the computer science and health care sectors. After screening 11,310 articles, we present findings from 56 applications from interrelated areas of population health and HSR, as well as their subdomains such as epidemiologic surveillance, health resource planning, access, and use and costs among diverse clinical and demographic populations., Results: In this companion review to our earlier systematic synthesis of the literature on visual analytics applications, we present findings in 6 major themes of interactive visualization applications developed for 8 major problem categories. We found a wide application of interactive visualization methods, the major ones being epidemiologic surveillance for infectious disease, resource planning, health service monitoring and quality, and studying medication use patterns. The data sources included mostly secondary administrative and electronic medical record data. In addition, at least two-thirds of the applications involved participatory co-design approaches while introducing a distinct category, embedded research, within co-design initiatives. These applications were in response to an identified need for data-driven insights into knowledge generation and decision support. We further discuss the opportunities stemming from the use of interactive visualization methods in studying global health; inequities, including social determinants of health; and other related areas. We also allude to the challenges in the uptake of these methods., Conclusions: Visualization in health has strong historical roots, with an upward trend in the use of these methods in population health and HSR. Such applications are being fast used by academic and health care agencies for knowledge discovery, hypotheses generation, and decision support., International Registered Report Identifier (irrid): RR2-10.2196/14019., (©Jawad Chishtie, Iwona Anna Bielska, Aldo Barrera, Jean-Sebastien Marchand, Muhammad Imran, Syed Farhan Ali Tirmizi, Luke A Turcotte, Sarah Munce, John Shepherd, Arrani Senthinathan, Monica Cepoiu-Martin, Michael Irvine, Jessica Babineau, Sally Abudiab, Marko Bjelica, Christopher Collins, B Catharine Craven, Sara Guilcher, Tara Jeji, Parisa Naraei, Susan Jaglal.

Arterial stiffness, as measured by carotid-femoral pulse wave velocity (cfPWV), is elevated after spinal cord injury (SCI). In the uninjured population, exercise training has been shown to reduce arterial stiffness. In a randomized, multi-center clinical trial, we evaluated the impact of two exercise interventions on cardiovascular disease risk factors in persons with chronic SCI. A total of 46 adults with motor-complete SCI with neurological levels of injury between the fourth cervical and sixth thoracic spinal cord segments (C4-T6) were randomly assigned to either body-weight-supported treadmill training (BWSTT) or arm-cycle ergometer training (ACET). Participants trained 3 days per week for 24 weeks. Exercise session duration progressed gradually to reach 30 and 60 min for ACET and BWSTT, respectively. The primary outcome was arterial stiffness, assessed by cfPWV, and was measured at baseline, 12 weeks of training, and at 24 weeks. Secondary outcomes included cardiorespiratory fitness (CRF) and cardiometabolic health measures and were measured before and after completion of training. Fourteen participants per intervention arm completed the exercise intervention. Our results show no effect of either exercise intervention on arterial stiffness ( p  = 0.07) and cardiometabolic health measures ( p  > 0.36). However, peak oxygen uptake increased with ACET compared with BWSTT ( p  = 0.04). The findings of this trial demonstrate that although 24 weeks of upper-body exercise improved CRF in persons with motor-complete SCI ≥T6, neither intervention resulted in improvements in arterial stiffness or cardiometabolic health measures. ClinicalTrials.gov identifier: NCT01718977.

Objective: To examine the associations among social networks and loneliness on health and life satisfaction in adults with chronic spinal cord injury/dysfunction (SCI/D)., Design: Cross-sectional telephone survey study., Setting: Tertiary spinal cord injury rehabilitation center in Ontario, Canada., Participants: Community-dwelling adults with chronic SCI/D (N=170)., Interventions: Not applicable., Main Outcome Measures: The main outcome measures were the Short-Form 36 to assess health and the Life Satisfaction-11 to assess life satisfaction., Results: A hierarchical regression model predicting physical health accounted for 24% (P<.001) of the variance. The only social network variable to significantly contribute to the model was having a higher proportion of network members living in one's household (P<.05). A model predicting mental health accounted for 44% (P<.001) of the variance, with having a higher proportion of network members living in one's household (P<.05) and lower feelings of loneliness (P<.001) associated with better mental health. Finally, the model predicting life satisfaction accounted for 62% (P<.001) of the variance, with lower greater levels of social network intimacy (P<.01) and lower feelings of loneliness (P<.001) being significant predictors., Conclusions: These findings highlight the importance of having access to network members in one's home for better physical and mental health after SCI/D as well as the negative association between loneliness and mental health and life satisfaction. There is a need for approaches to ensure that people with SCI/D in the community feel supported to mitigate feelings of loneliness to optimize their health and wellbeing., (Copyright © 2021 The American Congress of Rehabilitation Medicine.

Purpose: This review describes the effects of Whole Body Vibration therapy (WBV) for reducing fat mass (%/kg) among healthy (no comorbid disease) overweight and obese adults., Materials and Methods: Systematic literature search was conducted using Medline, Embase, Cochrane, CINAHL, and PubMed databases up to 27 th March 2019. Studies evaluating the effects of WBV therapy on fat mass as a primary or secondary outcome among healthy (no comorbid disease), overweight or obese adults (Body Mass Index ≥25) were included., Results: Following the search, 2,420 studies were reviewed and 1,603 studies were selected for title and abstract screening. Of 153 studies considered for full-text review, 13 controlled trials were included in the systematic review. Two meta-analyses were performed for five studies. The first random effects ( I 2 = 70%, p -value = 0.02) meta-analysis, revealed a statistically significant mean change for percent fat mass (-2.56, 95% CI: -3.81, -1.31). The second fixed effects meta-analysis, revealed a significant mean change (-1.91, 95% CI: -2.64, -1.18) for fat mass/kg., Conclusion: This systematic review and meta-analyses indicate a positive effect of Whole Body Vibration therapy on reducing fat mass (%/kg), especially when combined with conventional weight loss interventions specifically, diet and exercise.IMPLICATIONS FOR REHABILITATIONWhole Body Vibration therapy may assist obese and bariatric clients with weight loss.Whole Body Vibration therapy with conventional weight loss strategies may augment reductions in fat mass among obese clients in rehabilitation setting.

People experience rapid bone loss shortly after a spinal cord injury (SCI), but the long-term bone changes are yet to be confirmed. This study showed that trabecular bone may have reached a steady state, whereas cortical bone continued to decline in people with a chronic SCI (mean time post injury: 15.5 ± 10 years)., Introduction: (1) To explore changes in bone [primary measure: trabecular volumetric bone mineral density (vBMD); secondary measures: cortical vBMD, cortical thickness, cortical cross-sectional area (CSA), and polar moment of inertia] over 2 years in individuals with a chronic spinal cord injury (SCI). (2) To explore whether muscle density changes were potential correlates of the observed bone changes., Methods: This study is a secondary data analysis of a prospective, observational study involving 70 people with a chronic SCI (≥ 2 years post injury). The study included 4 strata of participants with diverse impairments: (1) Paraplegia (T1-T12) motor complete American Spinal Injury Association Impairment Scale (AIS) A/B (n = 23), (2) Paraplegia motor incomplete AIS C/D (n = 11), (3) Tetraplegia (C2-C8) AIS A/B (n = 22), and (4) Tetraplegia AIS C/D (n = 14). Peripheral quantitative computed tomography scans were taken at the 4% (distal tibia), 38% (diaphyseal tibia), and 66% (muscle cross-sectional area) tibia sites by measuring from the distal to proximal tibia starting at the inferior border of the medial malleolus. The tibia sites were assessed annually over a span of 2 years. Comparisons were made using a paired-samples t test and simple linear regression was used to adjust for sex, time post injury, and bisphosphonate use., Results: We observed no changes in trabecular vBMD at the 4% tibia site, but there was a statistically significant decline in cortical vBMD, cortical thickness, and CSA at the 38% tibia site. Changes in muscle density were not associated with the decreases observed in cortical bone., Conclusion: Our findings suggest that individuals with chronic SCI (mean duration of injury: 15.5 ± 10 years) may have reached a plateau in bone loss with respect to trabecular bone, but cortical bone loss can continue well into the chronic stages.

Introduction: Impaired balance leads to falls in individuals with motor incomplete spinal cord injury or disease (iSCI/D). Reactive stepping is a strategy used to prevent falls and Perturbation-based Balance Training (PBT) can improve this ability. Objective: The objective of this study was to determine if PBT results in greater improvements in reactive stepping ability than frequency-matched Conventional Intensive Balance Training (CIBT) in adults with iSCI/D. Design: Randomized clinical trial. Setting: Tertiary SCI/D rehabilitation center. Participants: Twenty-one adults with chronic (>1 year) iSCI/D were randomized. Due to one drop out 20 participants completed the study. Methods: Participants were randomly allocated to complete either PBT or CIBT three times per week for 8 weeks. Both programs included challenging static and dynamic balance tasks, but the PBT group also experienced manual external balance perturbations. Main Outcome Measures: Assessments of reactive stepping ability using the Lean-and-Release test were completed at baseline, and after 4 and 8 weeks of training, and 3 and 6 months after training completion. A blinded assessor evaluated secondary outcomes. Results: Twenty-five participants were screened and 21 consented; one withdrew. Ten PBT and 10 CIBT participants were included in analyses. Across all participants there were improvements in reactive stepping ability ( p = 0.049), with retention of improvements at follow up assessments. There were no differences in reactive stepping ability between groups [median (interquartile range): PBT 0.08 (0.68); CIBT 0.00 (0.22)]. One participant in the PBT group experienced a non-injurious fall during training. Conclusions: Balance training is beneficial for individuals with iSCI/D, but the addition of manual perturbations (i.e., PBT) did not prove advantageous for performance on a measure of reactive stepping ability.

Community participation following spinal cord injury/disease (SCI/D) can be challenging due to associated primary impairments and secondary health conditions as well as difficulties navigating both the built and social-emotional environment. To improve the quality of SCI/D rehabilitation care to optimize community participation, the SCI-High Project developed a set of structure, process and outcome indicators for adults with SCI/D in the first 18 months after rehabilitation admission., A pan-Canadian Working Group of diverse stakeholders: (1) defined the community participation construct; (2) conducted a systematic review of available outcomes and their psychometric properties; (3) constructed a Driver diagram summarizing available evidence associated with community participation; and (4) prepared a process map. Facilitated meetings allowed selection and review of a set of structure, process and outcome indicators., The structure indicator is the proportion of SCI/D rehabilitation programs with availability of transition living setting/independent living unit. The process indicators are the proportion of SCI/D rehabilitation inpatients who experienced: (a) a therapeutic community outing prior to rehabilitation discharge; and, (b) those who received a pass to go home for the weekend. The intermediary and final outcome measures are the Moorong Self-Efficacy Scale and the Reintegration to Normal Living Index., The proposed indicators have the potential to inform whether inpatient rehabilitation for persons with SCI/D can improve self-efficacy and lead to high levels of community participation post-rehabilitation discharge.
