Background Spinal epidural lipomatosis (SEL) is characterized by symptomatic neurogenic compression from adipose tissue in the spinal canal. The question arises whether patients with morbid obesity have higher volumes of epidural adipose tissue (EAT) in their lumbar spinal canal compared to patients with a normal weight and to which extent this decreases after bariatric surgery. Methods In this explorative study the lumbar EAT volume was assessed in 25 patients with morbid obesity (Body Mass Index (BMI)>40) using available lumbar magnetic resonance imaging (MRI) prior to their bariatric surgery. An age and gender matched control group (n=25) of patients with a normal weight (BMI 20-25) was used for comparison. Participants from the obesity group underwent a post-operative control MRI. Results The mean volume of EAT per MRI-slice of the group of patients with obesity was significantly higher than for the group of patients with normal weight (mean 83.3 mm3 ± 30.7 versus mean 56.5 mm3 ± 25; p Conclusions Patients with obesity have significantly larger volumes of EAT in comparison to patients with normal weight. After bariatric surgery, a significant weight loss coincided with a significant volumetric reduction of this adipose tissue in the spinal canal. Future prospective studies in patients with symptomatic SEL may elucidate whether decreases in EAT volume influence concurrent neurogenic claudication symptoms.

Contains fulltext : 290748.pdf (Publisher’s version ) (Open Access) Although several models for the prediction of surgical complications after primary total hip or total knee replacement (THA and TKA, respectively) are available, only a few models have been externally validated. The aim of this study was to externally validate four previously developed models for the prediction of surgical complications in people considering primary THA or TKA. We included 2614 patients who underwent primary THA or TKA in secondary care between 2017 and 2020. Individual predicted probabilities of the risk for surgical complication per outcome (i.e., surgical site infection, postoperative bleeding, delirium, and nerve damage) were calculated for each model. The discriminative performance of patients with and without the outcome was assessed with the area under the receiver operating characteristic curve (AUC), and predictive performance was assessed with calibration plots. The predicted risk for all models varied between

Background: this systematic review aims to evaluate the concordance between preoperative synovial fluid culture and intraoperative tissue cultures in patients with periprosthetic joint infection (PJI) undergoing total hip (THA) or knee arthroplasty (TKA) revision surgery. Methods: this review was conducted in accordance with the preferred reporting items for a systematic review and meta-analysis of diagnostic test accuracy studies (PRISMA-DTA) statement. Cochrane, Embase, PubMed, and Web of Science databases were searched to identify studies involving patients who had THA or TKA revision surgery for PJI and for whom preoperative synovial fluid culture and intraoperative tissue cultures were performed. Studies were only included if the diagnosis of PJI was based on the EBJIS (the European Bone and Joint Infection Society) or MSIS (Musculoskeletal Infection Society) criteria. Risk of bias was assessed using an amended version of Joanna Briggs Institute's (JBI) critical appraisal checklist for case series. Results: seven studies were included in this review comprising 1677 patients. All studies had a retrospective study design and five studies explored patients undergoing revision surgery of THA or TKA. Concordance rates varied between 52 % and 79 %, but different authors defined and calculated concordance differently. Six studies were judged as having an unclear to high risk of bias and one study as having a low risk of bias. Conclusions: the included studies showed a wide range of concordance rates between preoperative synovial fluid culture and intraoperative tissue cultures and the majority of studies had a high risk of bias. Higher-quality studies are warranted to obtain a more accurate estimate of this concordance rate. We recommend continuing the use of a system such as the EBJIS definition or MSIS criteria when diagnosing PJI.

To gain insight into visually impaired older people's views regarding acceptability of an adapted Falls Management Exercise programme, and to explore Postural Stability Instructors's perspectives on provision of the programme.Data from this qualitative study comprised interviews with nine visually impaired older people and two Postural Stability Instructors. Data were analysed using thematic analysis.Themes identified from interviews with the participants related to self-perception, exercise-related factors and facilitators to participation. Participants positioned themselves as not old or at risk of falls, felt exercises were not challenging enough and recommended that home exercise materials be offered in individually tailored formats. Themes identified from interviews with the instructors related to programme adaptations for visual impairments, exercises and facilitators to participation. Instructors recommended stratifying groups into levels of ability. Social time after the exercise sessions was deemed key in programme adherence by both participants and instructors.Visually impaired older people have similar barriers and facilitators to group-based falls prevention sessions as older people without visual impairment, but seem to have more difficulties in motivation to exercise at home. Both participants and instructors felt the main facilitator to adherence to group exercise sessions was the social time.Implications for rehabilitationVisually impaired older people have similar barriers and facilitators to group-based falls prevention sessions as older people without visual impairment, but seem to have more difficulties in motivation to exercise at home.Key recommended adaptations for falls prevention interventions in visually impaired older people include offering individually-tailored home exercise materials, stratifying groups into level of ability and involving social time.The social time after the exercise sessions was key in programme adherence.

Background Postoperative follow-up after hemiarthroplasty is part of routine based practice. However, these visits appear to be a significant burden since it concerns a frail population. The aim of this study was to confirm the current common practice regarding postoperative visits of patients treated with hemiarthroplasty and to evaluate the complication detection rate at these visits. Methods A national short survey was conducted among orthopedic surgeons working in 26 large Dutch teaching hospitals to test the hypothesis that postoperative follow-up is indeed common practice. Furthermore, a retrospective patient review was performed in all hemiarthroplasties implanted between January 2014 and December 2019. Results The response of the national survey was complete and showed that postoperative follow-up in patients treated with hemiarthroplasty is part of standard care according to 89% of respondents. A total of 1055 hips (1026 patients) were implanted with hemiarthroplasty during the studied period. Implant-related complications were identified in 68 hemiarthroplasties, with 31 of these hips going on to reoperation. Only 2 of these complications were picked up at standard planned follow-up leading to a complication detection rate of 0.3%. In contrast, complication detection rates of 47% and 16% were found at unplanned visits at the Emergency Department and the outpatient department, respectively. Conclusions Postoperative follow-up in patients treated with hemiarthroplasty is still the standard of care. However, this study revealed that the majority of implant-related complications are detected at unplanned visits and almost no at standard follow-up visits. Postoperative follow-up of patients treated with hemiarthroplasty could be abandoned in this frail population.

Obesity increases the risk of osteoarthritis and the chance of needing joint replacement arthroplasty to reduce lower limb joint pain. Although nonsurgical weight loss interventions can reduce hip and knee joint pain, bariatric surgery may be a more feasible treatment option for people with severe obesity. However, it is unclear whether weight loss through bariatric surgery can positively influence hip and knee joint pain. Our objective was to evaluate the influence of bariatric surgery on hip and knee joint pain in people with obesity by conducting a systematic review of the literature. The PubMed, EMBASE, and Cochrane bibliographic databases were searched for studies published between 1947 and September 2019. Risk of bias of the identified studies was independently assessed by 2 reviewers using JBI's Critical Appraisal Checklist for Case Series and the Newcastle-Ottawa Scale. This review included 23 studies, all of which evaluated knee pain and 9 of which also evaluated hip pain. Reported results regarding hip pain intensity and the proportion of participants with hip pain were too limited to draw useful conclusions. Reported results regarding knee pain suggest that weight loss after bariatric surgery reduced knee pain intensity, as well as the proportion of participants with knee pain. The overall risk of bias of the majority of included studies (83%; n = 19) was judged to be unclear to high. Four small studies were judged as having a low risk of bias. Results of this systematic review suggest that bariatric surgery can positively influence hip and knee joint pain, but conclusive evidence is lacking because most of the included studies were judged as having plausible bias overall and in their key domains. Well-designed randomized controlled trials evaluating the influence of bariatric surgery on hip and knee joint pain using standardized joint pain measures are needed.

Specifically, the purpose was to explore if and how participating could impact on the participants’ health-related quality of life (HRQoL) in terms of their daily lived experience regarding physical, mental, emotional and social well-being. A secondary purpose was to explore whether participating in the programme could positively influence participants’ balance, strength, falls efficacy, mobility and motor impairment of the trunk.Materials and Methods: This was an exploratory mixed-method Phase I feasibility study. A convenience sample of five older community-dwelling people after stroke participated in a novel eight-week multifactorial activity programme which included falls education, a mix of individually tailored and group-based strength and balance exercises, exploring limits of stability and safe landing techniques and a social element. Qualitative data from post-intervention interview transcripts with the participants and the physiotherapists who delivered the programme were thematically analysed using both deductive and inductive approaches to explore the participants’ and therapists’ experiences with the programme. Quantitative outcomes included balance, strength, falls efficacy, mobility and motor impairment of the trunk.Results: The programme was deemed feasible in terms of acceptability, implementation and practicality by the participants as well as the physiotherapists delivering the programme. The overarching theme regarding HRQoL identified that participating in the programme was perceived to empower the participants living with stroke and positively influenced their daily physical, mental, emotional and social well-being. Participant outcomes showed a change in the direction of improvements in balance, strength, mobility, motor impairment of the trunk and reduced concerns about falling. Subjectively, participants only reported perceived improvements in balance and strength.Conclusion: Running a novel multifactorial falls prevention activity programme for older community-dwelling people after stroke was feasible. Participating in the programme helped participants to perceive improved balance, strength and empower them to make meaningful changes, improving their daily lived experiences. A future fully powered study could build on these results to investigate physical improvements, prevention of falls and improvements to domains of HRQoOL.Keywords: accidental falls, aged, exercise, evaluation studies as topic, stroke, qualitative research, quality of life

Background Falls risk increases sharply with older age but many older people are unaware or underestimate their risk of falling. Increased population-based efforts to influence older people’s falls prevention behavior are urgently needed. The aim of this study was to obtain a group of older people’s collective perspectives on newly developed prototypes of audio-visual (AV) falls prevention messages, and evaluate changes in their falls prevention behaviour after watching and discussing these. Methods A mixed-method study using a community World Café forum approach. Results Although the forum participants (n = 38) mostly responded positively to the three AV messages and showed a significant increase in their falls prevention capability and motivation after the forum, the participants collectively felt the AV messages needed a more inspirational call to action. The forum suggested this could be achieved by means of targeting the message and increasing the personal connection. Participants further suggested several alternatives to online falls prevention information, such as printed information in places in the community, as a means to increase opportunity to seek out falls prevention information. Conclusions Falls prevention promotion messages need to be carefully tailored if they are to be more motivating to older people to take action to do something about their falls risk. A wider variety of revised and tailored AV messages, as one component of a community-wide falls prevention campaign, could be considered in an effort to persuade older people to take decisive action to do something about their falls risk. Trial registration This study was registered prospectively: NCT03154788. Registered 11 May 2017.

To determine reliability of the ABILHAND-Kids, explore sources of variation associated with these measurement results, and generate repeatability coefficients.A reliability study with a repeated measures design was performed in an ambulatory rehabilitation care department from a rehabilitation center, and a center for special education. A physician, an occupational therapist, and parents of 27 children with spastic cerebral palsy independently rated the children's manual capacity when performing 21 standardized tasks of the ABILHAND-Kids from video recordings twice with a three week time interval (27 first-, and 25 second video recordings available). Parents additionally rated their children's performance based on their own perception of their child's ability to perform manual activities in everyday life, resulting in eight ratings per child.ABILHAND-Kids ratings were systematically different between observers, sessions, and rating method. Participant × observer interaction (66%) and residual variance (20%) contributed the most to error variance (9%). Test-retest reliability was 0.92. Repeatability coefficients (between 0.81 and 1.82 logit points) were largest for the parents' performance-based ratings.ABILHAND-Kids scores can be reliably used as a performance- and capacity-based rating method across different raters. Parents' performance-based ratings are less reliable than their capacity-based ratings. Resulting repeatability coefficients can be used to interpret ABILHAND-Kids ratings with more confidence. Implications for Rehabilitation The ABILHAND-Kids is a valuable tool to assess a child's unimanual and bimanual upper limb activities. The reliability of the ABILHANDS-Kids is good across different observers as a performance- and capacity-based rating method. Parents' performance-based ratings are less reliable than their capacity-based ones. This study has generated repeatability coefficients for clinical decision making.

Strength and balance exercise programmes are effective in reducing the rate and risk of falls but uptake and adherence to community based programmes are low. Exergaming technology may be a promising tool to increase exercise uptake and adherence among seniors due to their motivational features. As yet, there is little published on the views of older people and therapists of their experiences of using Exergames to reduce falls in assisted living facilities that may inform implementation. This study is the qualitative component of a cluster randomized controlled trial that investigated the use of purpose-built strength and balance Exergames in community-dwelling older people in 18 assisted-living facilities in the UK. Data collection included 36 hours’ observation, semi-structured interviews with 5 physiotherapists, assistants and researchers, and 13 focus groups with residents of assisted living facilities who had participated in a 12 week Exergame programme. Transcribed data were analysed using thematic content analysis to identify themes arising from older users’ and therapists’ experiences of using the Exergames. Findings suggest that the senior users enjoyed using the strength and balance Exergames and reported physical, psychological and social benefits. Although some games were generally favoured, there was no overall consensus on game preferences although social components, feedback, music and colourful animation appeared to increase the appeal of the Exergames. This is the first study exploring older users and therapists’ perceptions of exergames in assisted living facilities and provides valuable insight into the barriers, facilitators, contextual factors and perceived benefits or drawbacks following 12 weeks use.

The number of falls and fall-associated injury rates among older people continues to rise worldwide. Increased efforts to influence older people's falls prevention behaviour are needed. A two-phase exploratory community-based participatory study was conducted in Western Australia. First, three prototype audio-visual (AV) falls prevention messages were designed collaboratively with six older people. Second, the messages' effect on community-dwelling older people's knowledge, awareness and motivation to take action regarding falls prevention was explored using focus groups. Data were analysed using thematic analysis to explore participants' responses to the messages. The participants' (n = 54) perspectives on the AV messages varied widely and stereotypes of ageing appeared to influence these. The presented falls facts (including falls epidemiology statistics) increased some participants' falls risk awareness and falls prevention knowledge. Other participants felt ready-to-use falls prevention information was lacking. Some expressed positive emotions or a personal connection to the messages and suggested the messages helped reduce ageing-related stigma. Strongly opposing viewpoints suggested that other participants identified implicit negative messages about ageing, which reduced their motivation with the messages. Suggestions to improve the message persuasiveness included adding more drama and tailoring messages to appeal to multiple age groups. Overall, the AV falls prevention messages designed in collaboration with older people elicited a divergent range of positive and negative perspectives from their peers, which was conceptualised by the overarching theme 'we all look at things different ways'. Opinions differed regarding whether the messages would appeal to older people. Public campaigns targeting falls prevention should be designed and tailored towards older peoples' differing perspectives about ageing.

Background Falls are the leading cause of fatal and non-fatal unintentional injuries in older people. The use of Exergames (active, gamified video-based exercises) is a possible innovative, community-based approach. This study aimed to determine the effectiveness of a tailored OTAGO/FaME-based strength and balance Exergame programme for improving balance, maintaining function and reducing falls risk in older people. Methods A two-arm cluster randomised controlled trial recruiting adults aged 55 years and older living in 18 assisted living (sheltered housing) facilities (clusters) in the UK. Standard care (physiotherapy advice and leaflet) was compared to a tailored 12-week strength and balance Exergame programme, supported by physiotherapists or trained assistants. Complete case analysis (intention-to-treat) was used to compare the Berg Balance Scale (BBS) at baseline and at 12 weeks. Secondary outcomes included fear of falling, mobility, fall risk, pain, mood, fatigue, cognition, healthcare utilisation and health-related quality of life, and self-reported physical activity and falls. Results Eighteen clusters were randomised (9 to each arm) with 56 participants allocated to the intervention and 50 to the control (78% female, mean age 78 years). Fourteen participants withdrew over the 12 weeks (both arms), mainly for ill health. There was an adjusted mean improvement in balance (BBS) of 6.2 (95% CI 2.4 to 10.0) and reduced fear of falling (p = 0.007) and pain (p = 0.02) in the Exergame group. Mean attendance at sessions was 69% (mean exercising time of 33 min/week). Twenty-four percent of the control group and 20% of the Exergame group fell over the trial period. The change in fall rates significantly favoured the intervention (incident rate ratio 0.31 (95% CI 0.16 to 0.62, p = 0.001)). The point estimate of the incremental cost-effectiveness ratio (ICER) was £15,209.80 per quality-adjusted life year (QALY). Using 10,000 bootstrap replications, at the lower bound of the NICE threshold of £20,000 per QALY, there was a 61% probability of Exergames being cost-effective, rising to 73% at the upper bound of £30,000 per QALY. Conclusions Exergames, as delivered in this trial, improve balance, pain and fear of falling and are a cost-effective fall prevention strategy in assisted living facilities for people aged 55 years or older.

Background Visually impaired older people (VIOP) have a higher risk of falling than their sighted peers, and are likely to avoid physical activity. The aim was to adapt the existing Falls Management Exercise (FaME) programme for VIOP, delivered in the community, and to investigate the feasibility of conducting a definitive randomised controlled trial (RCT) of this adapted intervention. Methods Two-centre randomised mixed methods pilot trial and economic evaluation of the adapted group-based FaME programme for VIOP versus usual care. A one hour exercise programme ran weekly over 12 weeks at the study sites (Newcastle and Glasgow), delivered by third sector (voluntary and community) organisations. Participants were advised to exercise at home for an additional two hours over the week. Those randomised to the usual activities group received no intervention. Outcome measures were completed at baseline, 12 and 24 weeks. The potential primary outcome was the Short Form Falls Efficacy Scale – International (SFES-I). Participants’ adherence was assessed by reviewing attendance records and self-reported compliance to the home exercises. Adherence with the course content (fidelity) by instructors was assessed by a researcher. Adverse events were collected in a weekly phone call. Results Eighteen participants, drawn from community-living VIOP were screened; 68 met the inclusion criteria; 64 participants were randomised with 33 allocated to the intervention and 31 to the usual activities arm. 94% of participants provided data at the 12 week visit and 92% at 24 weeks. Adherence was high. The intervention was found to be safe with 76% attending nine or more classes. Median time for home exercise was 50 min per week. There was little or no evidence that fear of falling, balance and falls risk, physical activity, emotional, attitudinal or quality of life outcomes differed between trial arms at follow-up. Conclusions The intervention, FaME, was implemented successfully for VIOP and all progression criteria for a main trial were met. The lack of difference between groups on fear of falling was unsurprising given it was a pilot study but there may have been other contributory factors including suboptimal exercise dose and apparent low risk of falls in participants. These issues need addressing for a future trial. Trial registration Current Controlled Trials ISRCTN ID: 16949845 Registered: 21 May 2015.

Rationale, aims, and objectives Patient sitters provide one-to-one care for hospital patients at high risk of falls. The study aimed to explore patient sitters' task readiness to assist in fall prevention on hospital wards. Method We conducted a cross-sectional survey. Respondents were patient sitters working in five hospitals providing medical, surgical, and aged care. The survey was developed using a theory of health behaviour change and used closed and open-ended items. Qualitative data were analysed using deductive content analysis. Results Participants (n = 90) identified that patient factors, such as confusion, were the most frequent cause of falls (n = 338, 74%); however, the most frequent strategies identified to prevent falls were focused on the environment (n = 164, 63%). The most frequent barrier participants identified to preventing falls (n = 124, 67%) also pertained to patients, including aggressive patient behaviours. In contrast, staff factors, such as handovers being adequate, were identified as the main enabler for sitters being able to complete their tasks effectively (n = 60, 81%). Participants strongly suggested (71%) that further, preferably practical, training would be helpful, even though 84% reported receiving prior fall prevention training. Nearly all participants (98%) were motivated to prevent their patients from falling. Conclusions There is a gap between what patient sitters report as the cause of falls (patient factors) and what was suggested to prevent falls (environment factors). Education and practical training addressing challenging patient behaviours may improve sitters' task readiness to assist in preventing falls on wards. Improving communication and cooperation between patient sitters and nursing staff is also important.

Purpose To understand the views and perceptions regarding the Functional Fitness MOT (FFMOT), a battery of functional tests followed by a brief motivational interview, of both the older people undergoing it and the health professionals delivering it. Patients and methods Physically inactive older adults (n=29) underwent the FFMOT and subsequently attended focus groups to share their perceptions of it and to discuss the barriers, motivators, health behavior change, and scope to improve physical activity (PA) levels. PA levels were recorded at baseline and again at 12 weeks together with a post-intervention questionnaire concerning behavior change. Participating physiotherapists and technical instructors were interviewed. Results Most participants felt they had learned about their abilities and comparisons with their peers, had a change in perception about the importance of good balance and strength, and felt the FFMOT helped raise their awareness of local and self-directed physical activity opportunities. Most felt their awareness of the need for PA had not changed, but 25% of participants started a new organized PA opportunity. The health professionals perceived the FFMOT as being easy to administer, educating, and motivating for participants to increase their PA. Space, time, finances, and insecurity about having the necessary skills to conduct the FFMOTs were seen as barriers in implementing the FFMOT in daily practice. Conclusion Over half of those offered the FFMOT accepted it, suggesting it is appealing. However, most participants felt they were already active enough and that their awareness of the need for PA had not changed. There were positive perceptions of the FFMOT from both professionals and older people, but both felt the FFMOT could be held in a community venue. The overall findings suggest that the FFMOT is feasible in the clinical setting, but its effectiveness has yet to be determined., Video abstract

Objective: The aim of this study was to explore whether information captured in falls reports in incident management systems could be used to explain how and why the falls occurred, with a view to identifying whether such reports can be a source of subsequent learnings that inform practice change. Methods: An analysis of prospectively collected falls incident reports found in the incident management systems from eight Western Australian hospitals during a stepped-wedge cluster-randomized controlled trial. The falls reported occurred in a cohort of older hospital patients (mean age = 82 y) on rehabilitation wards. Data coded from free-text comments in the incident reports were analyzed using deductive content analysis. Results: In the 493 analyzed falls incident reports, qualitative information describing aspects of the fall that clarified the patient, staff, and environment-related contributory factors was consistently low. Reports infrequently contained information about patients' and staff's call bell use behaviors (13%–19% of reports), fidelity of implementation of the care plan (8%) or environment-related factors such as bed settings (20%), and presence of clutter at the fall location (1%). The patients' account of the fall was present in less than 50% of reports, with an absence of concurrent text, which explained whether patient cognitive impairment was the reason for not obtaining this first-person account of the incident. Conclusions: Falls reports in hospital incident management systems may not capture adequate information to explain how and why falls occur. This could limit creation of effective feedback loops to drive quality improvement efforts and targeted practice change.

Background: Falls are the leading cause of fatal and non-fatal unintentional injuries in older people. In the community, 30% of adults aged 65 fall per year. The use of Exergames (active video-based exercise games) is a possible innovative, community-based approach to improve balance and function, and thus reduce falls risk. Objective: To determine the effectiveness of a tailored OTAGO based strength and balance Exergame programme for improving balance, maintaining function and reducing falls risk in older residents of assisted living facilities in the UK. Design: A two-arm cluster randomised controlled trial. Participants and setting Adults aged 55 years and older living in 18 assisted-living (sheltered housing) facilities (clusters) in the UK. Interventions: Tailored 12-week strength and balance Exergame programme, supported by physiotherapists or trained assistants plus standard care (physiotherapy advice and leaflet) versus standard care only. Main outcome measures: The primary outcome measure was balance at 12 weeks post-baseline, as assessed by the Berg Balance Scale (BBS). Secondary outcomes included: fear of falling, mobility, self-reported physical activity, falls risk, pain, mood, fatigue, cognition, healthcare utilisation and health-related quality of life; and self-reported falls over a 3-month period. Randomisation and blinding Clusters were randomised in blocks of two after participants were recruited and baseline data were collected. No blinding of those delivering or receiving the interventions, collecting or analysing data was possible. Results: Eighteen clusters were randomised (9 to each arm) with 56 participants allocated to the intervention and 50 to the control condition (78% female, mean age 78 years). Fourteen participants withdrew over the 12 weeks, mainly due to ill health, drop out rates did not differ per arm. Intention-to-treat analysis of respondents (49 Exergames; 43 control) revealed that balance was significantly improved at 12 weeks in the Exergame group; adjusted mean improvement in balance (BBS) of 6.2 (95% CI 2.4 to 10.0) and significant improvements in falls rate (p=0.001), fear of falling (p=0.007) and pain (p=0.02).The mean attendance at Exergames sessions during 12 weeks was 69% with a mean exercising time of 33 minutes/week. In the control group 12 (24%) participants fell 38 times over 3 months compared to 11 (20%) participants of the Exergame group who fell 17 times. The change in falls rates significantly favoured the intervention (incident rate ratio 0.31 (95% CI 0.16 to 0.62, p=0.001)). The point estimate of the incremental cost effectiveness ratio (ICER) was £15,209.80 per QALY. Using 10,000 bootstrap replications, at the lower bound of the NICE threshold of £20,000 per QALY, there was a 61% probability of Exergames being cost-effective. This rose to 73% at the upper bound of £30,000 per QALY. Conclusion: Exergames, as delivered in this trial, improve balance, pain and fear of falling and are an effective fall prevention strategy in assisted living facilities for older people. Health economic analysis suggests that Exergames represent a cost-effective fall prevention strategy.

Older patients in hospitals are at high risk of falls. Patient sitters are sometimes employed to directly observe patients to reduce their risk of falling although there is scant evidence that this reduces falls. The primary aim of this pilot survey (n = 31) was to explore the patient sitters' falls prevention capability, self-efficacy and the barriers and enablers they perceived influenced their ability to care for patients during their shifts. Feedback was also sought regarding training needs. Most (90%) participants felt confident in their role. The most frequent reasons for falls identified were patient-related (n = 91, 64%), but the most frequent responses identifying preventive strategies were environment-related (n = 54, 64%), suggesting that the sitters' capability was limited. The main barriers identified to keeping patients safe from falling were patient-related (n = 36, 62%) such as cognitive impairment. However, opportunities that would enable sitters to do their work properly were most frequently categorized as being staff-related (n = 20, 83%), suggesting that the sitters have limited ability to address these barriers encountered. While 74% of sitters reported they had received previous training, 84% of participants would like further training. Patient sitters need more training, and work practice needs to be standardized prior to future research into sitter use for falls prevention.

Introduction In the UK, 1 in 5 people aged 75 and over live with sight loss. Visually impaired older people (VIOP) have an above average incidence of falls and 1.3–1.9 times more likely to experience hip fractures, than the general population. Older people with eye diseases are ∼3 times more likely than those with good vision, to limit activities due to fear of falling. This feasibility study aims to adapt the group-based Falls Management Exercise (FaME) programme to the needs of VIOP and carry out an external pilot trial to inform the design of a future definitive randomised controlled trial. Methods and design A UK based 2-centre mixed methods, randomised, feasibility study will be conducted over 28 months. Stakeholder panels, including VIOP, will make recommendations for adaptations to an existing exercise programme (FaME), to meet the needs of VIOP, promoting uptake and adherence, while retaining required effective components of the exercise programme. 80 VIOP aged 60 and over, living at home, ambulant with or without a walking aid, will be recruited in Newcastle (n=40) and Glasgow (n=40) through National Health Service (NHS) Trusts and third sector partners. Participants randomised into the intervention arm will receive the adapted FaME programme. Participants randomised into the control arm will continue with usual activity. Outcomes are, recruitment rate, adherence and validated measures including fear of falling and quality of life. Postintervention in-depth qualitative interviews will be conducted with a purposive sample of VIOP (N=10). Postural stability instructors will be interviewed, before trial-specific training and following the intervention. Ethics and dissemination Ethics approval was secured through the National Research Ethics Service (NRES) Committee North East, Newcastle and North Tyneside 2. Glasgow Caledonian University was approved as a non-NHS site with local ethics approval. Findings will be disseminated through peer-reviewed journals, national and international conferences.

Physiotherapy (PT) and occupational therapy (OT) are key professions providing treatment for the arm after stroke; however, knowledge about the content of these treatments is scant. Detailed data are needed to replicate interventions, evaluate their effective components, and evaluate PT and OT practice. This paper describes PT and OT treatment for the severely affected arm in terms of duration, content according to components and categories of the International Classification of Human Functioning, Disability and Health, and to analyze differences between professions.Design: This is a retrospective analysis of randomized trial data.46 patients after stroke with poor arm motor control recruited from inpatient neurological units from three rehabilitation centers in the Netherlands.PTs and OTs recorded duration and content of arm treatment interventions for 8 weeks using a bespoke treatment schedule with 15 International Classification of Human Functioning, Disability and Health categories.PTs and OTs spent on average 4-7 min per treatment session (30 min) on arm treatment. OTs spent significantly more time providing arm treatment and treatment at the activities level than PTs. PTs spent 79% of their arm treatment time on body functions, OTs 41%. OTs spent significantly more time on "moving around using transportation," "self care," and "household tasks" categories.Patients after stroke with a severely affected arm and an unfavorable prognosis for arm motor recovery receive little arm-oriented PT and OT. Therapists spent most arm treatment time on body functions. There was a considerable overlap in the content of PT and OT in 12 of the 15 categories. Results can be generalized only to patients with poor arm motor control and may not represent practice in other countries.

de Jong LD, Hoonhorst MH, Stuive 1, Dijkstra PU. Arm motor control as predictor for hypertonia after stroke: a prospective cohort study. Arch Phys Med Rehabil 2011;92:1411-7.Objectives: To analyze the development of hypertonia in the hemiparetic elbow flexors, and to explore the predictive value of arm motor control on hypertonia in a cohort of first-ever stroke survivors in the first 6 months poststroke.Design: A prospective cohort study.Setting: A cohort of stroke survivors from a large, university-affiliated hospital in The Netherlands.Participants: Patients (N=50) with first-time ischemic strokes and initial arm paralysis who were admitted to a stroke unit.Interventions: Not applicable.Main Outcome Measures: At 48 hours, 10 to 12 days, 3 and 6 months poststroke, hypertonia and arm motor control were assessed using the Modified Ashworth Scale and the Fugl-Meyer Assessment arm score.Results: The incidence rate of hypertonia reached its maximum before the third month poststroke (30%). Prevalence was 42% at 3 and 6 months. Participants with poor arm motor control at 48 hours poststroke were 13 times more likely to develop hypertonia in the first 6 months poststroke than those with moderate to good arm motor control. These results were not confounded by the amount of arm function training received.Conclusions: Hypertonia develops in a large proportion of patients with stroke, predominantly within the first 3 months poststroke. Poor arm motor control is a risk factor for the development of hypertonia.

QuestionDoes static stretch positioning combined with simultaneous neuromuscular electrical stimulation (NMES) in the subacute phase after stroke have beneficial effects on basic arm body functions and activities?DesignMulticentre randomised trial with concealed allocation, assessor blinding, and intention-to-treat analysis.ParticipantsForty-six people in the subacute phase after stroke with severe arm motor deficits (initial Fugl-Meyer Assessment arm score ≤ 18).InterventionIn addition to conventional stroke rehabilitation, participants in the experimental group received arm stretch positioning combined with motor amplitude NMES for two 45-minute sessions a day, five days a week, for eight weeks. Control participants received sham arm positioning (ie, no stretch) and sham NMES (ie, transcutaneous electrical nerve stimulation with no motor effect) to the forearm only, at a similar frequency and duration.Outcome measuresThe primary outcome measures were passive range of arm motion and the presence of pain in the hemiplegic shoulder. Secondary outcome measures were severity of shoulder pain, restrictions in performance of activities of daily living, hypertonia, spasticity, motor control and shoulder subluxation. Outcomes were assessed at baseline, mid-treatment, at the end of the treatment period (8 weeks) and at follow-up (20 weeks).ResultsMultilevel regression analysis showed no significant group effects nor significant time × group interactions on any of the passive range of arm motions. The relative risk of shoulder pain in the experimental group was non-significant at 1.44 (95% CI 0.80 to 2.62).ConclusionIn people with poor arm motor control in the subacute phase after stroke, static stretch positioning combined with simultaneous NMES has no statistically significant effects on range of motion, shoulder pain, basic arm function, or activities of daily living.Trial registrationNTR1748.

Background Increasing physical activity (PA) brings many health benefits, but engaging people in higher levels of PA after their 60s is not straightforward. The Functional Fitness MOT (FFMOT) is a new approach which aims to raise awareness about the importance of components of fitness (strength, balance, flexibility), highlight benefits of PA, engages older people in health behavior change discussions, and directs them to local activity resources. This battery of tests combined with a brief motivational interview has not been tested in terms of feasibility or effectiveness. Objective To assess whether the FFMOT, provided in a health care setting, is appealing to older patients of a community physiotherapy service and to understand the views and perceptions of the older people undergoing the FFMOT regarding the intervention, as well as the views of the physiotherapy staff delivering the intervention. Secondary aims are to assess the feasibility of carrying out a phase 2 pilot randomized controlled trial of the FFMOT, in the context of a community physiotherapy service, by establishing whether enough patients can be recruited and retained in the study, and enough outcome data can be generated. Methods A mixed-methods feasibility study will be conducted in two physiotherapy outpatient clinics in the United Kingdom. A total of 30 physically inactive, medically stable older adults over the age of 60 will be provided with an individual FFMOT, comprising a set of six standardized, validated, age-appropriate tests aimed at raising awareness of the different components of fitness. The results of these tests will be used to provide the participants with feedback on performance in comparison to sex and age-referenced norms. This will be followed by tailored advice on how to become more active and improve fitness, including advice on local opportunities to be more active. Subsequently, participants will be invited to attend a focus group to discuss barriers and motivators to being more active, health behavior change, and the scope for individuals to improve their PA levels. To inform the design of a future trial, descriptive (eg, recruitment and retention rates), quantitative (Community Healthy Activities Model Program for Seniors; CHAMPS physical activity questionnaire), and qualitative data (focus group discussions, semi-structured staff interviews) will be collected. Results Recruitment and enrolment for the trial started in September 2015. Follow-up will be completed in June 2016. Results are expected to be available at the end of 2016. Discussion Allied health professionals play a key role in encouraging older adults to increase their PA, but with little evidence on how best to do this within their clinical practice. The purpose of this feasibility study is to examine the introduction of a new service: The FFMOT. The views and perceptions of the older people undergoing the FFMOT and relating to its delivery in clinical practice will be explored. Data, which will inform the feasibility of a randomized controlled trial of effectiveness of the FFMOT in promoting improved PA, will be reported.

Background Goniometric measurements of hemiplegic arm joints must be reliable to draw proper clinical and scientific conclusions. Previous reliability studies were cross-sectional and based on small samples. Knowledge about the contributions of sources of variation to these measurement results is lacking. Objective The aims of this study were to determine the interobserver reliability of measurements of passive range of motion (PROM) over time, explore sources of variation associated with these measurement results, and generate smallest detectable differences for clinical decision making. Design This investigation was a measurement-focused study with a longitudinal design, nested within a 2-arm randomized controlled trial. Methods Two trained physical therapists assessed 7 arm movements at baseline and after 4, 8, and 20 weeks in 48 people with subacute stroke using a standardized protocol. One physical therapist performed the passive movement, and the other read the hydrogoniometer. The therapists then switched roles. The relative contributions of several sources of variation to error variance were explored with analysis of variance. Results Interobserver reliability coefficients ranged from .89 to .97. The PROM measurements were influenced by error variance ranging from 31% to 50%. The participant × time interaction made the largest contribution to error variance, ranging from 59% to 81%. Smallest detectable differences were 6 to 22 degrees and were largest for shoulder movements. Limitations Verification of shoulder pain and hypertonia as sources of error variance led to a substantial number of unstable variance components, necessitating a simpler analysis. Conclusions The assessment of PROM with a standardized protocol, a hydrogoniometer, and 2 trained physical therapists yielded high interobserver reliability indexes for all arm movements. Error variance made a large contribution to the variation in measurement results. The resulting smallest detectable differences can be used to interpret future hemiplegic arm PROM measurements with more confidence.

Een CVA leidt in ongeveer 60 procent van de gevallen tot een afunctionele arm. Uitblijven van functieherstel maakt de arm vatbaar voor het ontwikkelen van complicaties zoals contracturen. Om complicaties te voorkomen en het herstel van de arm te bevorderen kunnen tijdens de revalidatie verschillende fysiotherapeutische interventies worden toegepast. Helaas zijn er daarvan maar weinig geschikt voor CVA-patienten die hun arm niet willekeurig kunnen inschakelen. Voor de interventies die wel kunnen worden toegepast (duurrek, repetitieve bilaterale armtraining, elektrostimulatie) is de wetenschappelijke evidentie zwak of gering: niet duidelijk is of deze interventies contractuurvorming voldoende kunnen voorkomen of bestrijden. Voor het toepassen in de fysiotherapeutische praktijk worden in dit hoofdstuk enkele aanbevelingen gedaan, maar duidelijk is dat meer en beter onderzoek noodzakelijk is.

Purpose. To assess whether our measurement protocol using two raters simultaneously yielded reliable passive range of motion measurements of the hemiplegic arm. Additionally, motion ranges were correlated to several factors to examine the concurrent validity of these measurements. Method. Two raters simultaneously assessed five arm motions at baseline, after five and ten weeks in respectively 18, 13 and 12 stroke patients. One tester made the passive movement and the other read the hydrogoniometer. Raters then switched roles. Results. Intraclass correlation coefficients revealed high agreement between the raters with intraclass correlation coefficients (ICCs) ranging between 0.84 and 0.99. Standard errors of measurement and smallest detectable differences were large for shoulder abduction. Significant correlations were found between shoulder external rotation and flexion. All arm motions correlated negatively to pain at the end range of these motions. Shoulder external rotation and flexion were significantly correlated to the time post stroke. Concurrent validity with Ashworth Scale, Fugl-Meyer Assessment and Barthel Index was limited. Conclusions. The current measurement protocol yielded high reliability indices and seems useful for further use. However, standard error of measurement and smallest detectable difference for shoulder abduction were high, implying the neccesity to include a large sample size in future studies. Correlations revealed that restricted range of arm motions relate to the time post-stroke and coincide with pain.
