Since December 2019, the coronavirus disease 2019 (COVID-19) has become a public health emergency. COVID-19 has already been classified as a category B infectious disease according to the Law of the People's Republic of China on the Prevention and Treatment of Infectious Diseases, and control measures for category A infectious diseases have been adopted. The National Health Commission has also published diagnosis and treatment protocols to guide the clinical diagnosis and treatment. With the accumulating experience of treating COVID-19 patients, particularly severely and critically ill patients, in clinical practice, our understanding of COVID-19 has continuously deepened. With regard to varying degrees of respiratory, physical, and psychological dysfunction in patients,[1] it is vital to standardize respiratory rehabilitation techniques and procedures for respiratory rehabilitation in various regions. Hence, we combined the opinions of frontline epidemic control experts and reviewed the evidence in relevant literature. Based on the “Coronavirus Disease 2019 Respiratory Rehabilitation Guidelines (First Edition),”[2] we organized experts in evidence-based medicine, respiratory and critical care medicine, and rehabilitation medicine in China, and invited some experts at the frontline of epidemic control in Wuhan and other cities in Hubei province to jointly draft these recommendations.

Osteoarthritis (OA) is frequently associated with loss of articular cartilage and is more common in elderly patients. Progranulin (PGRN) is a chondrogenic factor. However, the role of PGRN in inflammatory articular chondrocyte arthritis and related mechanisms has not been elucidated. In vitro cultured chondrocytes were divided into control group, LPS group that was treated with 1 μg/ml lipopolysaccharide (LPS), and PGRN group, in which LPS-stimulated chondrocytes were treated with PGRN (5 μM and 10 μM). The survival rate of chondrocytes was detected by tetrazolium salt colorimetry (MTT method). MMP-3, tissue metalloproteinase inhibitor 1 (TIMP-1), and MMP-3/TIMP-1 ratio were assessed by Western blot. The expressions of FAK and MAPK were detected by Western blot. TNF-α and IL-β secretion was evaluated by ELISA. Chondrocyte survival rate was decreased, Caspase 3 activity increased, MMP-3 expression upregulated, TIMP-1 expression reduced, MMP-3/TIMP-1 ratio elevated, FAK and MAPK expressions downregulated, and TNF-α and IL-1β secretions enhanced in LPS group (P < 0.05). PGRN significantly promoted the survival of LPS-treated chondrocytes, attenuated Caspase 3 activity, decreased MMP-3 level, enhanced TIMP-1 level, decreased MMP-3/TIMP-1 ratio, upregulated FAK and MAPK, and inhibited TNF-α and IL-1β secretions dose dependently (P < 0.05). PGRN can reduce the apoptosis of osteoarthritic chondrocytes, promote cell proliferation, reduce secretion of inflammatory factors, and delay the progression of osteoarthritis possibly through regulating FAK/MAPK pathway.

We synthesize the literature on broader health and social impacts on people with disabilities arising from lockdown-related measures. Methods: Scoping review with thematic analysis. Up to mid-September 2020, seven scientific databases and three pre-print servers were searched to identify empirical or perspective papers addressing lockdown-related disparities experienced by people with disabilities. Snowballing searches and experts’ consultation also occurred. Two independent reviewers took eligibility decisions and performed data extractions. Results: Out of 1026 unique references, 85 addressed lockdown-related disparities experienced by people with disabilities. Ten primary and two central themes were identified: (1) Disrupted access to healthcare (other than for COVID-19); (2) Reduced physical activity leading to health and functional decline; (3) From physical distance and inactivity to social isolation and loneliness; (4) Disruption of personal assistance and community support net-works; (5) Children with disabilities disproportionally affected by school closures; (6) Psychological consequences of disrupted routines, activities, and support; (7) Family and informal caregiver burden and stress; (8) Risks of maltreatment, violence, and self-harm; (9) Reduced employment and/or income exacerbating disparities; and (10) Digital divide in access to health, education, and support services. Lack of disability-inclusive response and emergency preparedness and structural, pre-pandemic disparities were the central themes. Conclusions: Lockdown-related measures to contain the COVID-19 pandemic can disproportionally affect people with disabilities with broader impact on their health and social grounds. Lack of disability-inclusive response and emergency preparedness and pre-pandemic disparities created structural disadvantages, exacerbated during the pandemic. Both structural disparities and their pandemic ramifications require the development and implementation of disability-inclusive public health and policy measures. publishersversion published

Although we are currently overwhelmed by the astonishing speed of infection of the Covid-19 pandemic, and the daily onslaught of new, and ever-worsening predictions, it is vital that we begin to prepare for the aftershocks of the pandemic. Prominent among this will be the cohort of post-intensive case survivors who have been mechanically ventilated and will likely experience short- and medium-term consequences. The notion that patients surviving intensive care and mechanical ventilation for several weeks can be discharged home without further medical attention is a dangerous illusion. Post Intensive Care Syndrome and other severe conditions will require not only adequate screening but early rehabilitation and other interventions. Action must be taken now to prepare for this inevitable aftershock to the healthcare system.

Objectives: To develop a protocol for a scoping review mapping as well as thematically analyzing the literature on the effect of, and responses to, the coronavirus disease 2019 (COVID-19) pandemic, focused on people with disabilities with other layers of individual vulnerability or social disadvantage. Methods: We will search scientific databases (Medline/PubMed, Web of Science, Scopus, AgeLine, PsycINFO, CINAHL, ERIC) and preprint servers (MedRxiv, SocArXiv, PsyArXiv). Google searches, snowballing, and key-informant strategies were also used, including a focus on the gray literature (eg, official reports). Peer-reviewed and preprint publications will be covered in 6 languages, and the gray literature in English. Publications will be included if they address individuals with disabilities; the COVID-19 pandemic or subsequent socioeconomic or occupational effects; and individual or social vulnerabilities, including any form of discrimination, marginalization, or social disadvantage. Two independent reviewers will perform eligibility decisions and key data extractions. Beyond mapping the literature, the results will thematically analyze any disproportionate risks people with disabilities and other forms of vulnerability experience in terms of being infected by COVID-19, having severe health consequences, and facing negative socioeconomic effects. Actions taken or recommended to reduce identified inequalities will also be synthesized. Our entire research team, with diverse backgrounds, will be involved in the synthesis. Conclusions: This review, which we plan to expedite, aims to inform policy makers, health authorities, disability advocates, and other stakeholders regarding the needs and ways to promote equity and disability-inclusive responses to the COVID-19 pandemic and the resultant socioeconomic shockwaves.

In the context of the White Book on Physical and Rehabilitation Medicine (PRM) in Europe this paper deals with the scope and competencies of PRM starting from its definition as the “medicine of functioning.” PRM uses the rehabilitative health strategy as its core strategy together with the curative strategy. According to the complexity of disabling health conditions, PRM also refers to prevention and maintenance and provides information to the patients and other caregivers. The rehabilitation process according to the so- called rehabilitation cycle including an assessment and definition of the (individual) rehabilitation goals, assignment to the rehabilitation program evaluation of individual outcomes. PRM physicians treat a wide spectrum of diseases and take a transversal across most of the medical specialties. They also focus on many functional problems such as immobilization, spasticity, pain syndromes, communication disorders, and others. The diagnosis in PRM is the interaction between the medical diagnosis and a PRM-specific functional assessment. The latter is based on the ICF conceptual framework, and obtained through functional evaluations and scales: these are classified according to their main focus on impairments, activity limitations or participation restrictions ; environmental and personal factors are included as barriers or facilitators. Interventions in PRM are either provided directly by PRM physicians or within the PRM team. They include a wide range of treatments, including medicines, physical therapies, exercises, education and many others. Standardized PRM programs are available for many diseases and functional problems. In most cases rehabilitation is performed in multi-professional teams working in a collaborative way, as well as with other disciplines under the leadership of a PRM physician and it is a patient-centered approach. Outcomes of PRM interventions and programs, showed reduction of impairments in body functions, activity limitations, and impacting on participation restrictions, and also reduction in costs as well as decrease in mortality for certain groups of patients.

Os Peroneum is an accessory ossicle located within the substance of the peroneus longus tendon that can cause pain in the lateral aspect of the foot. The painful Os Peroneum syndrome arises from a wide variety of conditions, such as impingement, fractures or diastasis of the Os Peroneum and can lead to tenosynovitis or rupture of the peroneus longus tendon. The differential diagnosis of lateral foot pain should consider this syndrome. Although diagnosis is mainly based in clinical features, imaging plays a significant role both in confirming the diagnosis and in therapeutic orientation. According to the literature, treatment varies with clinical severity, but is mostly surgical due to the syndrome’s typical acute presentation – the Os Peroneum fracture. The authors report an atypical case of chronic Os Peroneum syndrome without fracture that was documented by several imaging methods and treated conservatively by means of a customized rehabilitation programme achieving complete symptomatic resolution., Revista da Sociedade Portuguesa de Medicina Física e de Reabilitação, v. 31, n. 2 (2019): Ano 27

After stroke, approximately 80% of patients have upper limb impairment. Upper limb is then a key issue in neurorehabilitation. The objective of this study was to evaluate the efficacy of self-rehabilitation program of upper limb after stroke, in Benin. It was a randomised controlled trial concerning 59 patients presenting hemiplegia more than 6 months after stroke. The 28 patients of experimental group have executed a self-rehabilitation program during 8 week at home. The control group had 31 patients who received no treatment related to the study. Patients have been evaluated before the treatment (T0), at the end of the treatment (T1) and 8 weeks after later5T2). Le primary outcome was the manual ability assessed by ABILHAND Stroke for Benin. The secondary outcomes were: neurological impairments (Fugl- Meyer), manual dexterity (Box and Block Test, Wolf Motor Function Test) and quality of life (Whoquol-Brief). Two way repeated measure ANOVA in intention to treat was did for analysis. The experimental group improved significantly their manual ability in comparison to the control group (p

Background : Prevention of chronicization of low back pain requires accurate detection of at-risk patients. Questionnaires have been validated, including the STarT Back Tool (SBST) and the Örebro Musculoskeletal Pain Screening Questionnaire (OMPSQ). This review aims to compare these questionnaires in terms of predictive value and in terms of aims, to guide the choice in clinical practice. Methods : This study is a semi-systematic literature review. Studies evaluating at least one of the questionnaires and written between 1997 and October 10th 2017 were selected from Pubmed database. Inclusion criteria were pain duration

Introduction/Background: Telerehabilitation is a promising approach for patients with multiple sclerosis (MS), but uncertainties about patients’ preferences remain. The aim of this study was to investigate the access to technologies of patients with MS and their willingness to use them to receive rehabilitation services. Materials and Methods: 200 consecutive patients with MS filled out a specific questionnaire during a follow-up visit. This 6-page paper questionnaire was built to obtain information about needs, accesses, interests and perspectives of telerehabilitation for patients with MS. Descriptive statistics, Chi-Squared tests and logistic regression analysis were used to characterize the sample and survey answers. Results: The meanage of our sample was 44(±13) years. 71% were women. 49% of the patients were unemployed. The median EDSS score was 2.5, and 77% of the patients had a score of 4 or less on this scale. 91% of the patients regularly used internet, while 73% used apps. A substantial proportion of the sample reported an interest in using telecommunication technologies to receive a program of physical exercises (62%), information and personalized advice about physical activity and MS (69%), as well as to communicate with the caregivers (75%). One third of the patients was not interested in receiving telerehabilitation interventions (32%), especially among patients with moderate or severe disability (EDSS>4) and non-workers. Conclusion: The use of technologies to provide rehabilitation services is desirable by patients with MS, and most of these patients have access to the needed technologies. However, patients with moderate-to-severe disability and non-workers have, in average, less access and ease to use these technologies in a rehabilitation purpose. Given their high needs and strong barriers to benefit from rehabilitation, a special effort should be done to promote the use of telecommunications in this perspective.

Robotics and upper limb rehabilitation after stroke Thierry Lejeune Collaborator: S. Dehem, M. Gilliaux, G. Stoquart, C. Detrembleur Institut de Recherche Expérimentale et Clinique, Neuro Musculo Skeletal Lab NMSK, Brussels, Belgium Cliniques universitaires Saint-Luc, Service de médecine physique et réadaptation, Brussels, Belgium This talk will be divided in two parts: a general introduction about robotic assisted upper limb rehabilitation after stroke; and, the presentation of the result of a RCT. Introduction/Background Upper limb (UL) robotic assisted therapy (RAT) is promising for stroke rehabilitation. It allows to apply motor relearning principles. Systematic reviews show effectiveness at the at the early and chronic stage. In addition to conventional therapy (CT), RAT has been shown to decrease UL impairment. When RAT is provided as partial substitution of CT, it is supposed to be at least as effective as CT. A few studies demonstrated that RAT might be more effective than CT. Its effectiveness has been less studied in the acute phase than in the chronic one. Assessments have usually been restricted to the two first domains of the International Classification of Functioning framework (ICF). RCT Aim: To perform a pragmatic multicentric single-blind randomized controlled trial to evaluate UL RAT effectiveness, used as partial substitution to CT, in acute stroke patients, following the three ICF domains. Methods: Forty-five acute stroke patients were randomized into two groups (CT group, n=22 and RAT group, n=23). Both interventions were dose-matched about treatment duration and lasted nine weeks. The CT group followed a standard rehabilitation. In the RAT group, four sessions of CT (25%) were substituted by RAT each week. RAT consisted of moving the paretic UL along a reference trajectory while the robot provided an assistance as needed. A blinded assessor evaluated patients before, just after intervention and at 6-month post-stroke according to ICF. Results: Twenty-eight patients were assessed after intervention. UL motor control (Fugl Meyer +16%; p=0.05) and gross manual dexterity (Box and Block test +10 blocks; p=0.02) improved significantly more in RAT group than in CT group at 6-month post-stroke. Ability to perform activities and social participation tended also to improve more in RAT group (p=0.06-0.16). Conclusion: RAT during acute stage of stroke rehabilitation is more effective than CT to improve UL motor control and gross manual dexterity, and is at least as effective as CT for activity and participation.

O objetivo deste caso clínico é destacar o papel da toxina botulínica tipo A no tratamento da espasticidade e os seus benefícios na melhoria da qualidade de vida, tendo em conta a evolução clínica de um doente com síndrome de Leigh. A síndrome de Leigh é uma encefalomielopatia subaguda necrotizante, doença neurológica progressiva com inicio geralmente antes dos 12 meses de idade e que não tem nenhum tratamento específico. A espasticidade é um dos possíveis sintomas que pode precipitar várias complicações. Este caso clínico mostra os efeitos da toxina botulínica tipo A no controlo da espasticidade focal severa durante o crescimento de um doente na tentativa de combater a dor e minimizar as deformidades ortopédicas. Apesar de não existir nenhuma medida objetiva disponível, a evolução clínica e as informações dadas pelo doente e pela sua família confirmam uma melhoria na qualidade de vida., Revista da Sociedade Portuguesa de Medicina Física e de Reabilitação, v. 25, n. 1 (2014): Ano 22

Introduction/Background: Stride duration continuously fluctuates in a complex manner over time, displaying long-range autocorrelations (LRA). The presence of such temporal dynamics is thought to be a critical marker of health and their breakdown as an index of pathological condition, especially associated to dynamic stability in locomotion. However, neurophysiological mechanisms generating such correlations remain a matter of debate. Material and Methods: To further investigate their origin and the influence of pathological locomotion, we studied LRA from 20 parkinsonian patients walking on treadmill and overground at a comfortable speed. The presence of LRA was based on scaling properties of the series variability (Hurst exponent) and the shape of the power spectral density (α exponent). Functional status of each patient was assessed using MDS-UPDRS and modified H&Y scale. Furthermore, to precise the relationship between LRA and the dynamic stability, objective and subjective measures of balance was collected using BESTest and ABC Scale. Spearman’s correlation coefficients were calculated. Results: LRA were highlighted in all patients. However, Hurst and α exponents were significantly higher during treadmill walking (p

Introduction/Background: In a Phase III, randomized, double-blind placebo-controlled study conducted in 34 sites from 9 countries, two doses of abobotulinumtoxinA (Dysport®) 500 and 1000 units (U) were shown to be efficacious on muscle tone for the treatment of hemiparetic adults post stroke or traumatic brain injury (TBI) with a favourable safety profile.1. Materials and Methods: 243 patients received abobotulinumtoxinA 500 or 1000 U or placebo by intramuscular injection into their primary targeted muscle group (PTMG, selected from extrinsic finger flexors, wrist flexors and elbow flexors) and at least two other upper limb muscles, including shoulder muscles. Treatment was administered in a volume of 5.0 mL using electrostimulation. Doses administered to upper limb muscles are reported here. Results: For the abobotulinumtoxinA 500 U group, mean (SD) doses (U) administered in fingers flexors were: 93.5 (17.0) for flexor digitorium profundus (FDP), 95.4 (14.3) for flexor digitorium superficialis (FDS) and 76.9 (26.8) for other finger flexors (flexor pollis longus, adductor pollicis); in wrist flexors: 92.2 (18.1) for flexor carpi radialis (FCR) and 89.9 (25.7) for flexor carpi ulnaris (FCU); in elbow flexors: 88.3 (28.5) for brachioradialis, 148.5 (60.2) for brachialis and 108.6 (49.5) for other elbow muscles (biceps brachii, pronator teres) and 122.2 (44.1) in shoulder muscles (triceps brachii, pectoralis major, subscapularis, latissimus dorsi). For the abobotulinumtoxinA 1000 U group, doses administered were 195.5 (25.9) for FDP, 196.8 (28.4) for FDS, 157.0 (53.3) for other finger flexors, 178.1 (45.5) for FCR, 171.2 (45.2) for FCU, 172.1 (44.8) for brachioradialis, 321.4 (103.2) for brachialis, 216.5 (92.2) for other elbow muscles and 300.0 (129.1) in shoulder muscles. Conclusion: In this Phase III worldwide study in hemiparetic patients with upper limb spasticity post stroke/TBI, mean doses administered were 76.9–196.8 U for muscles in the finger flexors, 89.9-178.1 U for muscles in wrist flexors, 88.3–321.4 U for muscles in the elbow flexors and 122.2–300.0 U in shoulder muscles. Total dose administered (in the PTMG and at least 2 upper limb muscles) was 500 or 1000 U, which was previously shown to improve muscle tone in this patient population.

Introduction/Background: Kinematics is recommended for the quantitative assessment of upper limb movements. The aims of this study were to determine the age effects on upper limb kinematics and establish reference standards in healthy subjects. Materials and Methods: Three hundred and seventy healthy subjects, aged from 3 to 93 years, participated to the study. Twenty-eight kinematic indices were computed from two unidirectional (i.e., reaching a target and performing a back-and-forth movement) and two geometrical (i.e., drawing a circle and a square) tasks (1). Each task was performed ten consecutive times with the REAplan, a distal effector robotic device that allows upper limb displacements in the horizontal plane. Results: For both unidirectional tasks, the speed index showed an increase during childhood, a maturation in young adults and a decrease in the elderly. Moreover, for the back-and-forth movements, the smoothness results were more reproducible during the ten cycles of movements in young adults than in children and old subjects. Finally, the accuracy and straightness indices did not show any age effect for both unidirectional tasks. For both geometrical tasks, the speed index showed a decrease along the whole life and the smoothness index showed an improvement during childhood, a maturation in young adults and a deterioration in the elderly. Finally, the accuracy index did not show any age effect for both geometrical tasks. Conclusion: This study was the first to use a robotic device to assess the age effects on upper limb kinematics and establish reference standards in subjects aged from 3 to 93 years.

OBJECTIVE: To assess the reliability of kinematic, mechanical and energetic gait variables at short (1 day) and medium (1 month) intervals in adult patients after stroke. DESIGN: Prospective study. SUBJECTS: Ten patients with chronic post-stroke (mean age 53.5 years; age range 25–80 years). METHODS: Three-dimensional gait analysis was performed 3 times in these subjects: at baseline (T0), after 1 day (T1) and after 1 month (T2). The reliability of the gait analysis was tested by comparing gait variables measured at T1 and T0 (1 day interval), at T2 and T0 (1 month interval). The inter-session reliability of kinematic, mechanical and energetic variables was calculated by intra-class correlation coefficient (ICC). RESULTS: The reliability of kinematic variables ranged from excellent to moderate (ICC ≥ 0.51), except for the ankle position at heel strike (ICC = 0.44). The reliability of mechanical and energetic variables ranged from excellent to good (ICC ≥ 0.71). The most reliable variable was external mechanical work (ICC = 0.96). The kinematic, mechanical and energetic variables did not change significantly between T0, T1 and T2 (repeated-measures analysis of variance). CONCLUSION: Kinematic, mechanical and energetic gait variables present good reliability when measured at 1 day and 1 month intervals in adult patients after stroke.

Balance recovery after tripping often requires an active adaptation of foot placement. Thus far, few attempts have been made to actively assist forward foot placement for balance recovery employing wearable devices. This study aims to explore the possibilities of active forward foot placement through two paradigms of actuation: assistive moments exerted with the reaction moments either internal or external to the human body, namely ‘joint’ moments and ‘free’ moments, respectively. Both paradigms can be applied to manipulate the motion of segments of the body (e.g., the shank or thigh), but joint actuators also exert opposing reaction moments on neighbouring body segments, altering posture and potentially inhibiting tripping recovery. We therefore hypothesised that a free moment paradigm is more effective in assisting balance recovery following tripping. The simulation software SCONE was used to simulate gait and tripping over various ground-fixed obstacles during the early swing phase. To aid forward foot placement, joint moments and free moments were applied either on the thigh to augment hip flexion or on the shank to augment knee extension. Two realizations of joint moments on the hip were simulated, with the reaction moment applied to either the pelvis or the contralateral thigh. The simulation results show that assisting hip flexion with either actuation paradigm on the thigh can result in full recovery of gait with a margin of stability and leg kinematics closely matching the unperturbed case. However, when assisting knee extension with moments on the shank, free moment effectively assist balance but joint moments with the reaction moment on the thigh do not. For joint moments assisting hip flexion, placement of the reaction moment on the contralateral thigh was more effective in achieving the desired limb dynamics than placing the reaction on the pelvis. Poor choice of placement of reaction moments may therefore have detrimental consequences for balance recovery, and removing them entirely (i.e., free moment) could be a more effective and reliable alternative. These results challenge conventional assumptions and may inform the design and development of a new generation of minimalistic wearable devices to promote balance during gait.

Telerehabilitation systems have the potential to enable therapists to monitor and assist stroke patients in achieving high-intensity upper extremity exercise in the home environment. We adopted an iterative user-centred approach, including multiple data sources and meetings with end-users and stakeholders to define the user requirements for home-based upper extremity rehabilitation using wearable motion sensors for subacute stroke patients. We performed a requirement analysis consisting of the following steps: 1) context & groundwork; 2) eliciting requirements; 3) modelling & analysis; 4) agreeing requirements. During these steps, a pragmatic literature search, interviews and focus groups with stroke patients, physiotherapists and occupational therapists were performed. The results were systematically analysed and prioritised into “must-haves”, “should-haves”, and “could-haves”. We formulated 33 functional requirements: eighteen must-have requirements related to blended care (2), exercise principles (7), exercise delivery (3), exercise evaluation (4), and usability (2); ten should-haves; and five could-haves. Six movement components, including twelve exercises and five combination exercises, are required. For each exercise, appropriate exercise measures were defined. This study provides an overview of functional requirements, required exercises, and required exercise measures for home-based upper extremity rehabilitation using wearable motion sensors for stroke patients, which can be used to develop home-based upper extremity rehabilitation interventions. Moreover, the comprehensive and systematic requirement analysis used in this study can be applied by other researchers and developers when extracting requirements for designing a system or intervention in a medical context. This study provides an extensive overview of user requirements for home-based upper extremity rehabilitation using wearable motion sensors in stroke patients.These requirements can be used as a basis for developing home-based UE telerehabilitation interventions.Including these requirements may facilitate the clinical implementation of such telerehabilitation systems.The comprehensive and systematic approach used in this sudy can be applied by other researchers and developers when extracting requirements for designing a system or intervention in a medical context.

Purpose: Investigate pain, fatigue, depressive symptoms and sleep disturbance in young adults with cerebral palsy compared to references. Materials and methods: Young adults with cerebral palsy (n = 97, aged 21–34 years) and age-matched references from the general population (n = 190) rated pain using a numeric rating scale and fatigue, depressive symptoms, sleep disturbance and global health using Patient-Reported Outcomes Measurement Information System® short forms. Scores were compared between cerebral palsy subgroups and the reference population. Correlation coefficients and linear regression analyses assessed interrelationships of health issues and associations with global health. Results: Individuals with Gross Motor Function Classification System level I had less pain, fatigue and depressive symptoms, while individuals with levels II and III–V had more pain (53% and 56%, p < 0.001) and those with levels III–V more fatigue (39%, p = 0.035) than references (pain: 26%, fatigue: 14%). Pain and fatigue were more interrelated (correlation coefficients: 0.71 vs. 0.41) and stronger associated with global mental health in individuals with cerebral palsy. Conclusions: Young adults with Gross Motor Function Classification System levels II–V report more pain and those with levels III–V report more fatigue than references. Pain and fatigue are highly interrelated and specifically relate to mental health in individuals with cerebral palsy.Implications for rehabilitation Except for those in the highest level of motor function, young adults with cerebral palsy report higher levels of pain and fatigue compared to the general population of the same age. Pain and fatigue are strongly interrelated and associated with mental health in young adults with cerebral palsy. The present study recommends to monitor pain and fatigue in young adults with cerebral palsy with low levels of gross motor function. We advise rehabilitation professionals to consider combined treatment for both pain and fatigue.

Aim To examine the most relevant aspects of functioning of adults with cerebral palsy (CP) from their perspective, in order to develop an International Classification of Functioning, Disability and Health (ICF) Core Set for adults with CP. Method We conducted six focus group discussions with adults with CP without intellectual disability and seven interviews with adults with CP with intellectual disability and caregivers, addressing all ICF components. Meaningful concepts were identified from verbatim transcripts and linked to ICF categories by two independent researchers. Results In total, 31 adults with CP without intellectual disability (mean [SD] age 46y 1mo [14y 1mo]; 20 females, 11 males; Gross Motor Function Classification System [GMFCS] levels I–IV) and seven adults with CP and intellectual disability (mean [SD] age 25y 8mo [6y 8mo]; four females, three males; GMFCS levels III–V) participated. We identified 132 unique second‐level categories: 47 body functions, seven body structures, 43 activities and participation, and 35 environmental factors. The most frequently mentioned categories were emotional function, pain, muscle tone function, support of family, products and technology, and health services. Interpretation Adults with CP experienced problems in a broad range of body functions and activities and indicated the importance of environmental factors for functioning. The identified categories will be added to the list of candidate items to reach consensus on an ICF Core Set for adults with CP. What this paper adds Including the lived experience is crucial for fully understanding functioning of adults with cerebral palsy (CP).Adults with CP perceive environmental factors as essential elements for everyday functioning.Adults with intellectual disability should be considered as a group with specific problems., What this paper adds Including the lived experience is crucial for fully understanding functioning of adults with cerebral palsy (CP).Adults with CP perceive environmental factors as essential elements for everyday functioning.Adults with intellectual disability should be considered as a group with specific problems.

BACKGROUND: This international, multi-center cross-sectional study is one of the preparatory studies in the development of the International Classification of Functioning, Disability and Health (ICF) Core Sets for adults with cerebral palsy (CP) to describe their functioning and health.OBJECTIVE: To identify the most common problems in functioning of adults with CP presenting in healthcare services, and facilitating and hindering environmental factors, using the ICF as a reference.METHODS: Participants were adults with CP who visited healthcare services in the Netherlands, Sweden, Thailand, and the United States. Structured interviews were performed using an adapted version of the generic ICF checklist 2.1a (106 categories) to rate the participant's functioning and the impact of environmental factors. Descriptive statistics were used for frequency analysis.RESULTS: In total, 101 participants were included, of whom 69 without intellectual disability (mean age ± SD of 38.4 ± 14.7 y; 85.5% with spastic type of CP; Gross Motor Function Classification System (GMFCS) levels I-V) and 32 with intellectual disability (mean age ± SD of 25.0 ± 6.4 y; 71.9% with spastic type of CP; GMFCS levels I-V). A total of 104 ICF categories in the ICF checklist were frequently present in adults with CP: 27 body functions, 4 body structures, 53 activities and participation, and 20 environmental factors.CONCLUSIONS: The most common problems of adults with CP presenting in healthcare services are diverse and highly prevalent. The study results add the clinical perspective on relevant categories of functioning to the basis for developing the ICF Core Sets for adults with CP.

Objective: Spontaneous recovery is an important determinant of upper extremity recovery after stroke and has been described by the 70% proportional recovery rule for the Fugl–Meyer motor upper extremity (FM-UE) scale. However, this rule is criticized for overestimating the predictability of FM-UE recovery. Our objectives were to develop a longitudinal mixture model of FM-UE recovery, identify FM-UE recovery subgroups, and internally validate the model predictions. Methods: We developed an exponential recovery function with the following parameters: subgroup assignment probability, proportional recovery coefficient r k, time constant in weeks τ k, and distribution of the initial FM-UE scores. We fitted the model to FM-UE measurements of 412 first-ever ischemic stroke patients and cross-validated endpoint predictions and FM-UE recovery cluster assignment. Results: The model distinguished 5 subgroups with different recovery parameters (r 1 = 0.09, τ 1 = 5.3, r 2 = 0.46, τ 2 = 10.1, r 3 = 0.86, τ 3 = 9.8, r 4 = 0.89, τ 4 = 2.7, r 5 = 0.93, τ 5 = 1.2). Endpoint FM-UE was predicted with a median absolute error of 4.8 (interquartile range [IQR] = 1.3–12.8) at 1 week poststroke and 4.2 (IQR = 1.3–9.8) at 2 weeks. Overall accuracy of assignment to the poor (subgroup 1), moderate (subgroups 2 and 3), and good (subgroups 4 and 5) FM-UE recovery clusters was 0.79 (95% equal-tailed interval [ETI] = 0.78–0.80) at 1 week poststroke and 0.81 (95% ETI = 0.80–0.82) at 2 weeks. Interpretation: FM-UE recovery reflects different subgroups, each with its own recovery profile. Cross-validation indicates that FM-UE endpoints and FM-UE recovery clusters can be well predicted. Results will contribute to the understanding of upper limb recovery patterns in the first 6 months after stroke. ANN NEUROL 2020;87:383–393 Ann Neurol 2020;87:383–393.

Aim To determine development curves of communication and social interaction from childhood into adulthood for individuals with cerebral palsy (CP). Method This Pediatric Rehabilitation Research in the Netherlands (PERRIN)‐DECADE study longitudinally assessed 421 individuals with CP, aged from 1 to 20 years at baseline, after 13 years (n=121 at follow‐up). Communication and social interactions were assessed using the Vineland Adaptive Behavior Scales. We estimated the average maximum performance limit (level) and age at which 90% of the limit was reached (age90) using nonlinear mixed‐effects modeling. Results One‐hundred individuals without intellectual disability were aged 21 to 34 years at follow‐up (39 females, 61 males) (mean age [SD] 28y 5mo [3y 11mo]). Limits of individuals without intellectual disability, regardless of Gross Motor Function Classification System (GMFCS) level, approached the maximum score and were significantly higher than those of individuals with intellectual disability. Ages90 ranged between 3 and 4 years for receptive communication, 6 and 7 years for expressive communication and interrelationships, 12 and 16 years for written communication, 13 and 16 years for play and leisure, and 14 and 16 years for coping. Twenty‐one individuals with intellectual disability were between 21 and 27 years at follow‐up (8 females, 13 males) (mean age [SD] 24y 7mo [1y 8mo]). Individuals with intellectual disability in GMFCS level V showed the least favourable development, but variation between individuals with intellectual disability was large. Interpretation Individuals with CP and without intellectual disability show developmental curves of communication and social interactions similar to typically developing individuals, regardless of their level of motor function. Those with intellectual disability reach lower performance levels and vary largely in individual development. What this paper adds Communication and social interactions in individuals with cerebral palsy without intellectual disability develop similarly to typically developing individuals.Communication and social interactions of individuals with intellectual disability develop less favourably and show large variation., What this paper adds Communication and social interactions in individuals with cerebral palsy without intellectual disability develop similarly to typically developing individuals.Communication and social interactions of individuals with intellectual disability develop less favourably and show large variation.

Transcranial direct current stimulation (tDCS) is a promising tool to improve and speed up motor rehabilitation after stroke, but inconsistent clinical effects refrain tDCS from clinical implementation. Therefore, this study aimed to assess the need for individualized tDCS configurations in stroke, considering interindividual variability in brain anatomy and motor function representation. We simulated tDCS in individualized MRI-based finite element head models of 21 chronic stroke subjects and 10 healthy age-matched controls. An anatomy-based stimulation target, i.e. the motor hand knob, was identified with MRI, whereas a motor function-based stimulation target was identified with EEG. For each subject, we simulated conventional anodal tDCS electrode configurations and optimized electrode configurations to maximize stimulation strength within the anatomical and functional target. The normal component of the electric field was extracted and compared between subjects with stroke and healthy, age-matched controls, for both targets, during conventional and optimized tDCS. Electrical field strength was significantly lower, more variable and more frequently in opposite polarity for subjects with stroke compared to healthy age-matched subjects, both for the anatomical and functional target with conventional, i.e. non-individualized, electrode configurations. Optimized, i.e. individualized, electrode configurations increased the electrical field strength in the anatomical and functional target for subjects with stroke but did not reach the same levels as in healthy subjects. Considering individual brain structure and motor function is crucial for applying tDCS in subjects with stroke. Lack of individualized tDCS configurations in subjects with stroke results in lower electric fields in stimulation targets, which may partially explain the inconsistent clinical effects of tDCS in stroke trials.

Background Stroke survivors show deteriorated physical functioning and physical activity levels. Physical activity levels of stroke survivors are generally low. It is increasingly recognized that physical activity is a multidimensional construct that cannot be captured in a single outcome. In-depth insight into multidimensional physical activity patterns may guide the development and timing of targeted rehabilitation interventions. This longitudinal cohort study explored how multidimensional physical activity outcomes develop during recovery in the subacute phase after stroke and if changes in physical activity were correlated to recovery of lower limb motor function. Methods Patients were recruited during inpatient rehabilitation. At 3, 12, and 26 weeks post-onset, motor function was measured by the Fugl-Meyer Lower Extremity Assessment (FMA-LE). Physical activity was measured with the Activ8 accelerometer in multiple outcomes: counts per minute during walking (CPMwalking; a measure of Intensity), number of active bouts (Frequency), mean length of active bouts (Distribution) and % of waking time in upright positions (Duration). Generalized estimating equations (GEE) were used to study changes in physical activity over time and the relation with the change in lower limb motor recovery. Results Thirty-nine patients (age 56 ± 9, 77% male, 89% ischemic stroke) were included. GEE models showed a significant main effect of time for PA Intensity (+ 13%, p = 0.007) and Duration (+ 64%, p = 0.012) between 3 and 12 weeks. Motor function did not show a significant effect in all PA models across the 3 timepoints (p > 0.020). A significant interaction effect of time × motor function was observed (p Conclusions Patterns of PA recovery depend on the PA dimensions: PA Intensity and Duration increased mostly between 3 and 12 weeks post-stroke, whereas Frequency and Distribution did not show substantial changes. Further, no strong associations with motor recovery and high inter-individual variability were documented, which underlies the need to consider factors specific to the disease, the individual patient and the context.

Background It is unclear how arm use in daily life changes after stroke since studies investigating the change in arm use poststroke are scarce. The aim of this study was to investigate the change in arm use during the first six months poststroke. Secondary aim was to compare arm use changes between arm recovery clusters. Methods Arm use was measured during week 3, 12, and 26 poststroke with accelerometers on the wrists and the nonaffected leg. Outcomes were the amount of affected and nonaffected arm use during sitting and standing per day and per sit/stand hour, and the daily ratio between arms. Arm function was measured with the Fugl-Meyer Upper Extremity Scale to identify recovery clusters (poor/moderate/excellent). Generalized estimating equations compared arm use outcomes between time points and between recovery clusters. Results Thirty-three stroke patients participated. Affected arm use per day increased between week 3 and 12 (30 %; p = 0.04) and it increased per sit/stand hour between week 3–12 (31 %; p Conclusions Affected arm use and the ratio between arms increase during the first 26 weeks poststroke especially in patients with excellent arm recovery.

Background Smoothness is commonly used for measuring movement quality of the upper paretic limb during reaching tasks after stroke. Many different smoothness metrics have been used in stroke research, but a ‘valid’ metric has not been identified. A systematic review and subsequent rigorous analysis of smoothness metrics used in stroke research, in terms of their mathematical definitions and response to simulated perturbations, is needed to conclude whether they are valid for measuring smoothness. Our objective was to provide a recommendation for metrics that reflect smoothness after stroke based on: (1) a systematic review of smoothness metrics for reaching used in stroke research, (2) the mathematical description of the metrics, and (3) the response of metrics to simulated changes associated with smoothness deficits in the reaching profile. Methods The systematic review was performed by screening electronic databases using combined keyword groups Stroke, Reaching and Smoothness. Subsequently, each metric identified was assessed with mathematical criteria regarding smoothness: (a) being dimensionless, (b) being reproducible, (c) being based on rate of change of position, and (d) not being a linear transform of other smoothness metrics. The resulting metrics were tested for their response to simulated changes in reaching using models of velocity profiles with varying reaching distances and durations, harmonic disturbances, noise, and sub-movements. Two reaching tasks were simulated; reach-to-point and reach-to-grasp. The metrics that responded as expected in all simulation analyses were considered to be valid. Results The systematic review identified 32 different smoothness metrics, 17 of which were excluded based on mathematical criteria, and 13 more as they did not respond as expected in all simulation analyses. Eventually, we found that, for reach-to-point and reach-to-grasp movements, only Spectral Arc Length (SPARC) was found to be a valid metric. Conclusions Based on this systematic review and simulation analyses, we recommend the use of SPARC as a valid smoothness metric in both reach-to-point and reach-to-grasp tasks of the upper limb after stroke. However, further research is needed to understand the time course of smoothness measured with SPARC for the upper limb early post stroke, preferably in longitudinal studies.

Background The cause of smoothness deficits as a proxy for quality of movement post stroke is currently unclear. Previous simulation analyses showed that spectral arc length (SPARC) is a valid metric for investigating smoothness during a multi-joint goal-directed reaching task. The goal of this observational study was to investigate how SPARC values change over time, and whether SPARC is longitudinally associated with the recovery from motor impairments reflected by the Fugl-Meyer motor assessment of the upper extremity (FM-UE) in the first 6 months after stroke. Methods Forty patients who suffered a first-ever unilateral ischemic stroke (22 males, aged 58.6 ± 12.5 years) with upper extremity paresis underwent kinematic and clinical measurements in weeks 1, 2, 3, 4, 5, 8, 12, and 26 post stroke. Clinical measures included amongst others FM-UE. SPARC was obtained by three-dimensional kinematic measurements using an electromagnetic motion tracking system during a reach-to-grasp movement. Kinematic assessments of 12 healthy, age-matched individuals served as reference. Longitudinal linear mixed model analyses were performed to determine SPARC change over time, compare smoothness in patients with reference values of healthy individuals, and establish the longitudinal association between SPARC and FM-UE scores. Results SPARC showed a significant positive longitudinal association with FM-UE (B: 31.73, 95%-CI: [27.27 36.20], P P P P P Conclusions The present findings show that, after stroke, recovery of smoothness in a multi-joint reaching task and recovery from motor impairments are longitudinally associated and follow a similar time course. This suggests that the reduction of smoothness deficits quantified by SPARC is a proper objective reflection of recovery from motor impairment, as reflected by FM-UE, probably driven by a common underlying process of spontaneous neurological recovery early post stroke.

Purpose: To determine childhood predictors of participation in domestic life and interpersonal relationships of young adults with cerebral palsy (CP). Materials and methods: This 13-year follow-up of an existing cohort (baseline age 9–13 years) included 67 young adults with CP (age 21–27 years). The Vineland adaptive behavior scales (VABS) and Life Habits questionnaire were used to assess attendance and difficulty in participation in domestic life and interpersonal relationships. Baseline factors were categorised according to the international classification of functioning, disability, and health. Stepwise multiple linear regression analyses determined significant predictors (p < 0.05). Results: Lower manual ability, intellectual disability (ID), epilepsy and lower motor capacity predicted decreased future participation in domestic life, and/or interpersonal relationships (explained variance R 2 = 67–87%), whereas no association was found with environmental and personal factors. Extending models with baseline fine motor skills, communication, and interpersonal relationships increased R 2 to 79–90%. Conclusions: Childhood factors account for 79–90% of the variation in young adult participation in domestic life and interpersonal relationships of individuals with CP. Children with limited motor capacity, low manual ability, ID, or epilepsy are at risk for restrictions in participation in young adulthood. Addressing fine motor, communication, and social skills in paediatric rehabilitation might promote young adult participation.Implications for rehabilitation Childhood risk factors for limited participation in domestic life and interpersonal relationships as a young adult with CP are ID, epilepsy, low manual ability, low motor capacity, and low activity & participation levels. In line with current practice, this study confirms the importance of addressing gross and fine motor skills in children with CP for their future participation in domestic life. In addition, results suggest that addressing communication and social skills during paediatric rehabilitation may optimise future participation in interpersonal relationships.

Fatigue related to Multiple Sclerosis (MS) is considered a multidimensional symptom, manifesting in several dimensions such as physical, cognitive, and psychosocial fatigue. This study investigated in 264 patients with severe primary MS-related fatigue (median MS duration 6.8 years, mean age 48.1 years, 75% women) whether subgroups can be distinguished based on these dimensions. Subsequently, we tested whether MS-related fatigue consists of a single common unidimensional factor. Subscale scores on four self-reported fatigue questionnaires, including the Checklist of Individual Strength, the Modified Fatigue Impact Scale, the Fatigue Severity Scale and the SF36 vitality, were used in a cluster analysis to identify patients with similar fatigue characteristics. Next, all 54 items were included in exploratory factor analysis to test unidimensionality. Study results show that in patients with a treatment indication for primary MS-related fatigue, fatigue profiles are based on severity and not on the various dimensions of fatigue. The three profiles found, suggested one underlying fatigue dimension, but this could not be confirmed. Factor analysis of all 54 items resulted in 8 factors, confirming the multidimensional construct of the included fatigue questionnaires.

To determine the long-term development of autonomy in participation of individuals with cerebral palsy (CP) without intellectual disability.Individuals with CP (n=189, 117 males, 72 females; mean age [SD] 21y 11mo [4y 11mo], range 12-34y); were assessed cross-sectionally (46%) or up to four times (54%), between the ages of 12 and 34 years. Autonomy in participation was classified using phase 3 of the Rotterdam Transition Profile. A logistic generalized estimating equation regression model was used to analyse autonomy in six domains (independent variables: age, Gross Motor Function Classification System [GMFCS] level, and interaction between age and GMFCS level). Proportions of autonomy were compared to references using binomial tests (p0.05).In most domains, over 90% of participants (n=189, 400 observations, 80% in GMFCS levels I and II) reached autonomy in participation in their late twenties, except for intimate/sexual relationships. Those in GMFCS levels III to V compared to those in GMFCS levels I and II had less favourable development of autonomy in the transportation, intimate relationships, employment, and housing domains, and more favourable development in the finances domain. Compared to references, fewer individuals with CP were autonomous in participation.This knowledge of autonomy may guide the expectations of young people with CP and their caregivers. Furthermore, rehabilitation professionals should address autonomy development in intimate relationships, employment, and housing, especially in individuals with lower gross motor function.Individuals with cerebral palsy without intellectual disability achieved autonomy in most participation domains. Regarding intimate relationships, they continued to have less experience compared to age-matched references. Development of autonomy was less favourable for individuals in Gross Motor Function Classification System levels III to V.AUTONOMÍA EN LA PARTICIPACIÓN EN LA PARÁLISIS CEREBRAL DESDE LA INFANCIA A LA EDAD ADULTA: OBJETIVO: Determinar el desarrollo a largo plazo de la autonomía en la participación de individuos con parálisis cerebral (PC) sin discapacidad intelectual. MÉTODO: Individuos con PC (n=189, 117 varones, 72 mujeres; edad media [DE] 21 años y 11 meses [4 años y 11meses], rango 12-34 años); fueron evaluados de forma transversal (46%) o hasta cuatro veces (54%), entre las edades comprendidas entre los 12 y los 34 años. La autonomía en la participación fue clasificada usando la fase 3 del perfil de transición de Rotterdam (Rotterdam Transition Profile). Se utilizó un modelo de regresión logístico generalizado estimando la ecuación para analizar la autonomía en 6 dominios (variables independientes: edad, nivel del Sistema de Clasificación de la Función Motora Gruesa, [GMFCS], y la interacción entre la edad y el nivel GMFCS). Las proporciones de la autonomía se compararon con las referencias mediante pruebas binomiales (p0,05). RESULTADOS: En la mayoría de los dominios, más del 90% de los participantes (n=189.400 observaciones, 80% en los niveles I y II de la GMFCS) alcanzaron la autonomía en la participación bien entrados los 20 años, excepto para las relaciones íntimas/sexuales. Aquellos en los niveles III y V de la GMFCS en comparación con los niveles I y II de la GMFCS tuvieron un desarrollo de la autonomía menos favorable en el transporte, relaciones íntimas, empleo y en el dominio de la vivienda, y un desarrollo más favorable en el dominio de las finanzas. En comparación con las referencias, menos individuos con PC fueron autónomos en la participación. INTERPRETACIÓN: Este conocimiento de la autonomía puede guiar las expectativas de los jóvenes con PC y de sus cuidadores. Además, los profesionales de la rehabilitación deberían abordar el desarrollo de la autonomía en las relaciones íntimas, el empleo y la vivienda, especialmente en aquellos individuos con una función motora gruesa más baja.AUTONOMIA NA PARTICIPAÇÃO EM PARALISIA CEREBRAL DA INFÂNCIA À VIDA ADULTA: OBJETIVO: Determinar o desenvolvimento em longo prazo da autonomia na participação de indivíduos com paralisia cerebral (PC) sem deficiência intelectual. MÉTODO: Indivíduos com PC (n=189, 117 do sexo masculino, 72 do sexo feminino; média de idade [DP] 21a 11m [4a 11m], variação 12-34a); foram avaliados transversalmente (46%) ou até quatro vezes (54%), entre as idades de 12 e 34 anos. A autonomia na participação foi classificada usando a fase 3 do Perfil de Transição de Rotterdam. Um modelo de regressão logística com generalizada com equações estimadas foi usado para analisar a autonomia em seis domínios (variáveis independentes: idade, Nível segundo o Sistema de Classificação da Função Motora Grossa [GMFCS], e interação entre idade e nível GMFCS). As proporções de autonomia foram comparadas com as referências usando testes binomiais (p0,05). RESULTADOS: Na maior parte dos domínios, cerca de 90% dos participantes (n=189.400 observações, 80% nos níveis GMFCS I e II) atingiram autonomia na participação no final da terceira década de vida, exceto para relações íntimas/sexuais. Aqueles nos níveis GMFCS III a V comparados com os níveis I e II tiveram desenvolvimento menos favorável nos domínios da autonomia no transporte, relações íntimas, emprego, e domicílio, e mais desenvolvimento mais favorável no domínio das finanças. Em comparação com as referências, menos indivíduos com PC foram autônomos na participação. INTERPRETAÇÃO: Este conhecimento sobre a autonomia pode guiar as expectativas de jovens com PC e seus cuidadores. Além disso, profissionais da reabilitação devem abordar o desenvolvimento da autonomia nas relações íntimas, emprego e domicílio, especialmente nos indivíduos com menor função motora grossa.

Objective: Despite the widespread use of botulinum toxin in ambulatory children with spastic cerebral palsy, its value prior to intensive physiotherapy with adjunctive casting/orthoses remains unclear. Design: A pragmatically designed, multi-centre trial, comparing the effectiveness of botulinum toxin + intensive physiotherapy with intensive physiotherapy alone, including economic evaluation. Subjects/patients: Children with spastic cerebral palsy, age range 4–12 years, cerebral palsy-severity Gross Motor Function Classification System levels I–III, received either botulinum toxin type A + intensive physiotherapy or intensive physiotherapy alone and, if necessary, ankle-foot orthoses and/or casting. Methods: Primary outcomes were gross motor func-tion, physical activity levels, and health-related quality-of-life, assessed at baseline, 12 (primary end-point) and 24 weeks (follow-up). Economic outcomes included healthcare and patient costs. Intention-to-treat analyses were performed with linear mixed models. Results: There were 65 participants (37 males), with a mean age of 7.3 years (standard deviation 2.3 years), equally distributed across Gross Motor Function Classification System levels. Forty-one children received botulinum toxin type A plus intensive physio-therapy and 24 received intensive physiotherapy treatment only. At primary end-point, one statistically significant difference was found in favour of intensive physiotherapy alone: objectively measured percentage of sedentary behaviour (–3.42, 95% confidence interval 0.20–6.64, p=0.038). Treatment costs were significantly higher for botulinum toxin type A plus intensive physiotherapy (8,963 vs 6,182 euro, p=0.001). No statistically significant differences were found between groups at follow-up. Conclusion: The addition of botulinum toxin type A to intensive physiotherapy did not improve the effectiveness of rehabilitation for ambulatory children with spastic cerebral palsy and was also not cost-effective. Thus botulinum toxin is not recommended for use in improving gross motor function, activity levels or health-related quality-of-life in this cerebral palsy age- and severity-subgroup.

The objective of the study was to gain an insight into the perceptions and experiences of patients with rheumatoid arthritis and a high cardiovascular disease risk (CVD-RA) when undergoing an exercise intervention aimed at improving their cardiorespiratory fitness. This qualitative study was part of a pilot study, which investigated the effects of an exercise intervention on cardiorespiratory fitness in patients with CVD-RA. Six patients were invited to participate in face-to-face semi-structured interviews. We invited patients who completed the exercise intervention as well as patients who withdrew from the exercise intervention. The interviews were analyzed according to the method of thematic analysis. Six patients were interviewed, of whom four patients completed and two patients discontinued the exercise intervention. The mean (SD) age was 58 (9.7) years, the median disease duration was 10 years, and five patients were female. The analyses revealed seven themes that provided insight into perceptions and experiences: (1) ability to understand reasons for actions; (2) the need to be seen; (3) reaching their maximum effort; (4) experiencing their limits; (5) wanting personalized exercise therapy; (6) happy to be physically active; (7) benefits of exercise. Patients perceived that they were able to perform a cardiopulmonary exercise test with maximum effort and achieved the prescribed intensity of the exercise intervention. They also experienced an improvement in their physical activity by incorporating physical activity in their daily live. Overarching principles that re-occurred in the themes were: the need to be viewed as a person and the importance of feeling safe.

PURPOSE: To develop and explore underlying dimensions of the Self-Regulation Assessment (SeRA) and psychometric features of potential components. Further, to identify associations between the SeRA and disability-management self-efficacy, type of diagnosis, and type of rehabilitation.MATERIALS AND METHODS: Based on a previously developed model of self-regulation, expert and patient opinions, and cognitive interviews, a list of 22 items on self-regulation (the SeRA) was constructed. The SeRA was included in a cross-sectional survey among a multi-diagnostic group of 563 former rehabilitation patients. Exploratory analyses were conducted.RESULTS: Respondents had a mean age of 56.5 (SD 12.7) years. The largest diagnostic groups were chronic pain disorder and brain injury. Four components were found within the SeRA, labelled as "insight into own health condition," "insight into own capabilities," "apply self-regulation," and "organization of help." Cronbach's alpha was high (total scale: 0.93, subscales: range 0.85-0.89). Only scores on the first subscale showed a ceiling effect. Subscale three showed the highest correlation with a self-efficacy measure. Small differences in SeRA total scores (range 71.6-78.1) were found between different diagnostic groups.CONCLUSION: The SeRA is a new self-regulation measure with four subscales. Further research is needed to establish the validity and reliability of the SeRA. IMPLICATIONS FOR REHABILITATIONThe Self-Regulation Assessment (SeRA) was developed to provide a comprehensive measurement of self-regulation among rehabilitation populations.The SeRA could potentially be used to identify persons with self-regulation problems at the start of rehabilitation treatment and measure outcomes of rehabilitation for self-regulation.The SeRA could potentially be used to help analyse outcomes of rehabilitation practice as well as evaluate interventions on self-regulation.

Objective: To assess the cost-effectiveness of a cardiac rehabilitation (CR) program specifically designed for cardiac patients with obesity vs standard CR. Design: Cost-effectiveness analysis based on observations in a randomized controlled trial. Setting: Three regional CR centers in the Netherlands. Participants: Cardiac patients (N=201) with obesity (BMI≥30 kg/m2) referred to CR. Interventions: Participants were randomized to a CR program specifically designed for patients with obesity (OPTICARE XL; N=102) or standard CR. OPTICARE XL included aerobic and strength exercise and behavioral coaching on diet and physical activity during 12 weeks, followed by a 9-month after-care program with “booster” educational sessions. Standard CR consisted of a 6- to 12-week aerobic exercise program, supplemented with cardiovascular lifestyle education. Main Outcome Measures: An economic evaluation, with an 18-month time horizon, in terms of quality-adjusted life years (QALYs) and costs from the societal perspective was performed. Costs were reported in 2020 Euros, discounted at a 4% annual rate, and health effects were discounted at a 1.5% annual rate. Results: OPTICARE XL CR and standard CR resulted in comparable health gain per patient (0.958 vs 0.965 QALYs, respectively; P=.96). Overall, OPTICARE XL CR saved costs (-€4542) compared with the standard CR group. The direct costs for OPTICARE XL CR were higher than for standard CR (€10,712 vs €9951), whereas indirect costs were lower (€51,789 vs €57,092), but these differences were not significant. Conclusions: This economic evaluation showed no differences between OPTICARE XL CR and standard CR in health effects and costs in cardiac patients with obesity.

Background: Fatigue is a frequently reported and disabling symptom in multiple sclerosis (MS). Objective: To investigate the effectiveness of an individual energy conservation management (ECM) intervention on fatigue and participation in persons with primary MS-related fatigue. Methods: A total of 86 severely fatigued and ambulatory adults with a definite diagnosis of MS were randomized in a single-blind, two-parallel-arm randomized clinical trial to the ECM group or the information-only control group in outpatient rehabilitation departments. Blinded assessments were carried out at baseline and at 8, 16, 26 and 52 weeks after randomization. Primary outcomes were fatigue (fatigue subscale of Checklist Individual Strength – CIS20r) and participation (Impact on Participation and Autonomy scale – IPA). Results: Modified intention-to-treat analysis was based on 76 randomized patients (ECM, n = 36; MS nurse, n=40). No significant ECM effects were found for fatigue (overall difference CIS20r between the groups = −0.81; 95% confidence interval (CI), −3.71 to 2.11) or for four out of five IPA domains. An overall unfavourable effect was found in the ECM group for the IPA domain social relations (difference between the groups = 0.19; 95% CI, 0.03 to 0.35). Conclusion: The individual ECM format used in this study did not reduce MS-related fatigue and restrictions in participation more than an information-only control condition.

Background Physical activity (PA) levels might be a simple overall physical function indicator of recovery in acutely hospitalized older adults; however it is unknown which amount and level of PA is associated with recovery. Our objective was to evaluate the amount and level of post discharge PA and its optimum cut-off values associated with recovery among acutely hospitalized older adults and stratified for frailty. Methods We performed a prospective observational cohort study including acutely hospitalized older adults (≥ 70 years). Frailty was assessed using Fried’s criteria. PA was assessed using Fitbit up to one week post discharge and quantified in steps and minutes light, moderate or higher intensity. The primary outcome was recovery at 3-months post discharge. ROC-curve analyses were used to determine cut-off values and area under the curve (AUC), and logistic regression analyses to calculate odds ratios (ORs). Results The analytic sample included 174 participants with a mean (standard deviation) age of 79.2 (6.7) years of whom 84/174 (48%) were frail. At 3-months, 109/174 participants (63%) had recovered of whom 48 were frail. In all participants, determined cut-off values were 1369 steps/day (OR: 2.7, 95% confidence interval [CI]: 1.3–5.9, AUC 0.7) and 76 min/day of light intensity PA (OR: 3.9, 95% CI: 1.8–8.5, AUC 0.73). In frail participants, cut-off values were 1043 steps/day (OR: 5.0, 95% CI: 1.7–14.8, AUC 0.72) and 72 min/day of light intensity PA (OR: 7.2, 95% CI: 2.2–23.1, AUC 0,74). Determined cut-off values were not significantly associated with recovery in non-frail participants. Conclusions Post-discharge PA cut-offs indicate the odds of recovery in older adults, especially in frail individuals, however are not equipped for use as a diagnostic test in daily practice. This is a first step in providing a direction for setting rehabilitation goals in older adults after hospitalization.

Objectives To investigate cartilage tissue turnover in response to a supervised 12-week exercise-related joint loading training program followed by a 6-month period of unsupervised training in patients with knee osteoarthritis (OA). To study the difference in cartilage tissue turnover between high- and low-resistance training. Method Patients with knee OA were randomized into either high-intensity or low-intensity resistance supervised training (two sessions per week) for 3 months and unsupervised training for 6 months. Blood samples were collected before and after the supervised training period and after the follow-up period. Biomarkers huARGS, C2M, and PRO-C2, quantifying cartilage tissue turnover, were measured by ELISA. Changes in biomarker levels over time within and between groups were analyzed using linear mixed models with baseline values as covariates. Results huARGS and C2M levels increased after training and at follow-up in both low- and high-intensity exercise groups. No changes were found in PRO-C2. The huARGS level in the high-intensity resistance training group increased significantly compared to the low-intensity resistance training group after resistance training (p = 0.029) and at follow-up (p = 0.003). Conclusion Cartilage tissue turnover and cartilage degradation appear to increase in response to a 3-month exercise-related joint loading training program and at 6-month follow-up, with no evident difference in type II collagen formation. Aggrecan remodeling increased more with high-intensity resistance training than with low-intensity exercise. These exploratory biomarker results, indicating more cartilage degeneration in the high-intensity group, in combination with no clinical outcome differences of the VIDEX study, may argue against high-intensity training.

Background Mobility is a key determinant and outcome of healthy ageing but its definition, conceptual framework and underlying constructs within the physical domain may need clarification for data comparison and sharing in ageing research. This study aimed to (1) review definitions and conceptual frameworks of mobility, (2) explore agreement on the definition of mobility, conceptual frameworks, constructs and measures of mobility, and (3) define, classify and identify constructs. Methods A three-step approach was adopted: a literature review and two rounds of expert questionnaires (n = 64, n = 31, respectively). Agreement on statements was assessed using a five-point Likert scale; the answer options ‘strongly agree’ or ‘agree’ were combined. The percentage of respondents was subsequently used to classify agreements for each statement as: strong (≥ 80%), moderate (≥ 70% and Results A variety of definitions of mobility, conceptual frameworks and constructs were found in the literature and among respondents. Strong agreement was found on defining mobility as the ability to move, including the use of assistive devices. Multiple constructs and measures were identified, but low agreements and variability were found on definitions, classifications and identification of constructs. Strong agreements were found on defining physical capacity (what a person is maximally capable of, ‘can do’) and performance (what a person actually does in their daily life, ‘do’) as key constructs of mobility. Conclusion Agreements on definitions of mobility, physical capacity and performance were found, but constructs of mobility need to be further identified, defined and classified appropriately. Clear terminology and definitions are essential to facilitate communication and interpretation in operationalising the physical domain of mobility as a prerequisite for standardisation of mobility measures.
