Comparing Short-Term Knee-Related Quality of Life and Associated Clinical Outcomes Between Youth With and Without a Sport-Related Knee Injury.

OBJECTIVE: To compare short-term changes in knee-related quality of life (QOL) and associated clinical outcomes between youth with and without a sport-related knee injury. DESIGN: Prospective cohort study. SETTING: Sport medicine and physiotherapy clinics. PARTICIPANTS: Youth (11-19 years old) who sustained an intra-articular, sport-related knee injury in the past 4 months and uninjured youth of similar age, sex, and sport. INDEPENDENT VARIABLE: Injury history. MAIN OUTCOME MEASURES: Knee-related QOL (Knee injury and Osteoarthritis Outcome Score, KOOS), knee extensor and flexor strength (dynamometry), physical activity (accelerometer), fat mass index (FMI; bioelectrical impedance), and kinesiophobia (Tampa Scale for Kinesiophobia, TSK) were measured at baseline (within 4 months of injury) and at 6-month follow-up. Wilcoxon rank sum tests assessed between-group differences for all outcomes. Regression models assessed the association between injury history and outcome change (baseline to 6-month follow-up), considering sex. The influence of injury type, baseline values, and physiotherapy attendance was explored. RESULTS: Participants' (93 injured youth, 73 uninjured control subjects) median age was 16 (range 11-20) years and 66% were female. Despite greater improvements in KOOS QOL scores (20; 95% confidence interval, 15-25), injured participants demonstrated deficits at 6-month follow-up (z = 9.3, P < 0.01) compared with control subjects, regardless of sex. Similar findings were observed for knee extensor and flexor strength and TSK scores but not for physical activity or FMI. Lower baseline values were associated with greater outcome changes in injured youth. CONCLUSIONS: Youth have worse knee-related QOL, muscle strength, and kinesiophobia early after a sport-related knee injury than control subjects. Despite improvements, deficits persist 6 months later.

An Exploration of Sedentary Behavior Patterns in Community-Dwelling People With Stroke: A Cluster-Based Analysis.

BACKGROUND AND PURPOSE: Long periods of daily sedentary time, particularly accumulated in long uninterrupted bouts, are a risk factor for cardiovascular disease. People with stroke are at high risk of recurrent events and prolonged sedentary time may increase this risk. We aimed to explore how people with stroke distribute their periods of sedentary behavior, which factors influence this distribution, and whether sedentary behavior clusters can be distinguished? METHODS: This was a secondary analysis of original accelerometry data from adults with stroke living in the community. We conducted data-driven clustering analyses to identify unique accumulation patterns of sedentary time across participants, followed by multinomial logistical regression to determine the association between the clusters, and the total amount of sedentary time, age, gender, body mass index (BMI), walking speed, and wake time. RESULTS: Participants in the highest quartile of total sedentary time accumulated a significantly higher proportion of their sedentary time in prolonged bouts (P < 0.001). Six unique accumulation patterns were identified, all of which were characterized by high sedentary time. Total sedentary time, age, gender, BMI, and walking speed were significantly associated with the probability of a person being in a specific accumulation pattern cluster, P < 0.001 - P = 0.002. DISCUSSION AND CONCLUSIONS: Although unique accumulation patterns were identified, there is not just one accumulation pattern for high sedentary time. This suggests that interventions to reduce sedentary time must be individually tailored.Video Abstract available for more insight from the authors (see the Video Supplemental Digital Content 1, available at: http://links.lww.com/JNPT/A343).

Perspectives of people with spinal cord injury learning to walk using a powered exoskeleton.

BACKGROUND: Powered exoskeletons for over ground walking were designed to help people with neurological impairments to walk again. Extended training in powered exoskeletons has led to changes in walking and physiological functions. Few studies have considered the perspective of the participants. The users' perspective is vital for adoption of assistive devices. We explored the expectations and experiences of persons with spinal cord injury, training with the ReWalk exoskeleton. METHODS: A qualitative research design with individual interviews was used. Eleven participants with spinal cord injury, taking part in 12 weeks of 4 times weekly training using the ReWalk, were interviewed before, immediately after, and 2 months after training. Interviews were audio recorded and transcribed verbatim. A six stage approach to thematic analysis was used. RESULTS: The theme consistently expressed was the exoskeleton allowed participants to do everyday activities, like everyone else, such as looking people in the eye or walking outside. Their experiences were captured in three categories: 1) learning, a description of both expectations for learning and perspectives on how learning occurred; 2) changing, perspectives on perceived changes with training; and 3) contributing, which captured participant perspectives on contributing to research, including the giving of direct feedback regarding the exoskeleton (i.e., what worked and what could be changed). CONCLUSIONS: Incorporating the view of the user in the design and refinement of exoskeletons will help ensure that the devices are appropriate for future users. Availability and support for the use of exoskeleton devices in community settings is an interim step to home use as the devices continue to improve.

Retraining walking over ground in a powered exoskeleton after spinal cord injury: a prospective cohort study to examine functional gains and neuroplasticity.

BACKGROUND: Powered exoskeletons provide a way to stand and walk for people with severe spinal cord injury. Here, we used the ReWalk exoskeleton to determine the training dosage required for walking proficiency, the sensory and motor changes in the nervous system with training, and the functionality of the device in a home-like environment. METHODS: Participants with chronic (> 1 yr) motor complete or incomplete spinal cord injury, who were primarily wheelchair users, were trained to walk in the ReWalk for 12 weeks. Measures were taken before, during, immediately after, and 2-3 months after training. Measures included walking progression, sitting balance, skin sensation, spasticity, and strength of the corticospinal tracts. RESULTS: Twelve participants were enrolled with 10 completing training. Training progression and walking ability: The progression in training indicated about 45 sessions to reach 80% of final performance in training. By the end of training, participants walked at speeds of 0.28-0.60 m/s, and distances of 0.74-1.97 km in 1 h. The effort of walking was about 3.3 times that for manual wheelchair propulsion. One non-walker with an incomplete injury became a walker without the ReWalk after training. Sensory and motor measures: Sitting balance was improved in some, as seen from the limits of stability and sway speed. Neuropathic pain showed no long term changes. Change in spasticity was mixed with suggestion of differences between those with high versus low spasticity prior to training. The strength of motor pathways from the brain to back extensor muscles remained unchanged. Adverse events: Minor adverse events were encountered by the participants and trainer (skin abrasions, non-injurious falls). Field testing: The majority of participants could walk on uneven surfaces outdoors. Some limitations were encountered in home-like environments. CONCLUSION: For individuals with severe SCI, walking proficiency in the ReWalk requires about 45 sessions of training. The training was accompanied by functional improvements in some, especially in people with incomplete injuries. TRIAL REGISTRATION: NCT02322125 Registered 22 December 2014.

The Feasibility and Longitudinal Effects of a Home-Based Sedentary Behavior Change Intervention After Stroke.

OBJECTIVE: To evaluate the feasibility and preliminary effects of a sedentary behavior change intervention on sedentary behavior, physical activity, function, and quality of life following inpatient stroke rehabilitation. DESIGN: Single-group, longitudinal, intervention study with 1-week baseline, 8-week intervention, and 8-week follow-up. SETTING: Community. PARTICIPANTS: Individuals (N=34) with subacute stroke recruited within 1 month following discharge home from inpatient stroke rehabilitation. INTERVENTION: STand Up Frequently From Stroke (STUFFS) intervention that involved interrupting and replacing sedentary time with upright activities (standing and walking) at home and in the community. A motivational wrist-worn activity monitor was used throughout the intervention. MAIN OUTCOME MEASURES: Primary outcomes were reach (enrolled/eligible), retention (completed/enrolled), satisfaction, and compliance with the intervention. Secondary outcomes were sedentary behavior, physical activity, lower extremity impairment, self-efficacy, cognitive status, mobility, and quality of life outcomes. RESULTS: Forty-four participants were eligible to participate. Of the eligible, 34 (77.3%; time since stroke onset: 3.5±1.1 months) were enrolled at baseline and 32 (94.1%) of the enrolled had complete data at follow-up. Satisfaction with the program was 89%. Sedentary time decreased by 54.2±13.7 minutes per day (P<.01) at postintervention and 26.8±14.0 minutes per day (P=.07) at follow-up, relative to baseline. There were significant improvements in walking speed, cognition, impairment, and self-reported quality of life over time (P<.05). Self-efficacy was high across all time points. The number of steps and time spent stepping were not statistically different across both time periods. CONCLUSIONS: The program was feasible to deliver in the home environment with good retention and satisfaction. Further research is required to test the effectiveness of the STUFFS program compared with usual care.

Evidence-based scientific exercise guidelines for adults with spinal cord injury: an update and a new guideline.

OBJECTIVES: To describe the process and outcomes of using a new evidence base to develop scientific guidelines that specify the type and minimum dose of exercise necessary to improve fitness and cardiometabolic health in adults with spinal cord injury (SCI). SETTING: International. METHODS: Using Appraisal of Guidelines, Research and Evaluation (AGREE) II reporting criteria, steps included (a) determining the guidelines' scope; (b) conducting a systematic review of relevant literature; (c) holding three consensus panel meetings (European, Canadian and International) to formulate the guidelines; (d) obtaining stakeholder feedback; and (e) process evaluation by an AGREE II consultant. Stakeholders were actively involved in steps (c) and (d). RESULTS: For cardiorespiratory fitness and muscle strength benefits, adults with a SCI should engage in at least 20 min of moderate to vigorous intensity aerobic exercise 2 times per week AND 3 sets of strength exercises for each major functioning muscle group, at a moderate to vigorous intensity, 2 times per week (strong recommendation). For cardiometabolic health benefits, adults with a SCI are suggested to engage in at least 30 min of moderate to vigorous intensity aerobic exercise 3 times per week (conditional recommendation). CONCLUSIONS: Through a systematic, rigorous, and participatory process involving international scientists and stakeholders, a new exercise guideline was formulated for cardiometabolic health benefits. A previously published SCI guideline was endorsed for achieving fitness benefits. These guidelines represent an important step toward international harmonization of exercise guidelines for adults with SCI, and a foundation for developing exercise policies and programs for people with SCI around the world.

Sleep Duration, Sedentary Behavior, Physical Activity, and Quality of Life after Inpatient Stroke Rehabilitation.

OBJECTIVE: The aim of this study was to describe accelerometer-derived sleep duration, sedentary behavior, physical activity, and quality of life and their association with demographic and clinical factors within the first month after inpatient stroke rehabilitation. MATERIALS AND METHODS: Thirty people with stroke (mean ± standard deviation, age: 63.8 ± 12.3 years, time since stroke: 3.6 ± 1.1 months) wore an activPAL3 Micro accelerometer (PAL Technologies, Glasgow, Scotland) continuously for 7 days to measure whole-day activity behavior. The Stroke Impact Scale and the Functional Independence Measure were used to assess quality of life and function, respectively. RESULTS: Sleep duration ranged from 6.6 to 11.6 hours/day. Fifteen participants engaged in long sleep greater than 9 hours/day. Participants spent 74.8% of waking hours in sedentary behavior, 17.9% standing, and 7.3% stepping. Of stepping time, only a median of 1.1 (interquartile range: .3-5.8) minutes were spent walking at a moderate-to-vigorous intensity (≥100 steps/minute). The time spent sedentary, the stepping time, and the number of steps differed significantly by the hemiparetic side (P < .05), but not by sex or the type of stroke. There were moderate to strong correlations between the stepping time and the number of steps with gait speed (Spearman r = .49 and .61 respectively, P < .01). Correlations between accelerometer-derived variables and age, time since stroke, and cognition were not significant. CONCLUSIONS: People with stroke sleep for longer than the normal duration, spend about three quarters of their waking hours in sedentary behaviors, and engage in minimal walking following stroke rehabilitation. Our findings provide a rationale for the development of behavior change strategies after stroke.

Compositional associations between movement-related behaviours and functional outcomes post-stroke.

PURPOSE: To examine the associations between the composition of movement-related behaviours (sedentary behaviour, sleep, standing, and stepping) and functional outcomes post-stroke. METHODS: This study included 34 adults with stroke (mean age: 64.6 ± 12.5 years; time since stroke: 3.5 ± 1.1 months) who underwent an 8-week sedentary behaviour intervention. Functional outcomes were assessed using the timed up and go (TUG) and gait speed tests. Compositional data analysis was used to investigate the relationships between movement-related behaviours and functional outcomes. RESULTS: The baseline composition of movement-related behaviours showed significant associations with changes in TUG (F = 4.28, p = 0.01) and gait speed (F = 4.63, p = 0.01) after the 8-week reducing sedentary behaviour intervention. Reallocating ≥ 30 min/day to stepping, while proportionally decreasing other movement-related behaviours, was associated with a significant change in TUG. Similarly, a relative reallocation of ≥ 40 min/day to stepping was associated with a clinically meaningful change in gait speed. CONCLUSIONS: This study highlights the importance of considering movement-related behaviours in relation to functional outcomes post-stroke. Reallocating at least 30 min per day to stepping, relative to a reduction in other movement-related behaviours, is associated with significant and meaningful change in functional outcomes.

Reallocating at least 30 minutes/day to stepping, relative to a decrease in other movement-related behaviours, is associated with a positive change in functional mobility after an 8-week post-stroke sedentary behaviour intervention.Relative to a decrease in other movement-behaviours, reallocating ≥ 40 minutes/day to stepping is associated with a meaningful change in gait speed.Reallocating time to standing or sleep at the expense of other movement behaviours is not associated with better functional mobility or gait speed.Finding the optimal balance in movement-related behaviours that favours more stepping may lead to improvements in both functional mobility and gait speed.

Patient and therapist perspectives on physical therapy outcome measures and engagement after stroke: A case study.

BACKGROUND: Outcome measures are highly recommended in stroke physical therapy, however, most of the existing research has been performed from the provider perspective. Understanding the patient perspective of outcome measures in conjunction with the therapist perspective may help to better support patient engagement and autonomy. PURPOSE: The purpose of this study was to explore patient and therapist perspectives on physical therapy outcome measures post-stroke. METHODS: This qualitative case study of a Canadian rehabilitation facility is based on patient-oriented research principles, with three patient partners embedded in the research team. Data collection included chart reviews, observations of physical therapy sessions, patient interviews, and therapist interviews. Field notes of observations and interview transcripts were analyzed using thematic analysis. RESULTS: Ten patients and seven therapists participated. Analysis revealed the following two themes: 1) tracking progress; and 2) partnership. Tracking progress included the expectations patients had for improvement, the importance of objectively measuring change and the functional improvement observed day by day. Partnership described the relationship between therapist and patient including communication, encouragement and affirmation, the therapist as expert and the gradual shift in autonomy from therapist to patient. CONCLUSION: Patients valued the objective results of outcome measures and were encouraged by measurable changes. Maximizing the use of physical therapy outcome measures may improve patient engagement and support relational autonomy.

Youth With a Sport-Related Knee Injury Exhibit Significant and Persistent Knee-Related Quality-of-Life Deficits at 12-Month Follow-up Compared to Uninjured Peers.

OBJECTIVE: We aimed to compare knee-related quality of life (QOL) between youth with and without an intra-articular, sport-related knee injury at baseline (≤4 months postinjury), 6-month, and 12-month follow-up, and assess the association between clinical outcomes and knee-related QOL. DESIGN: Prospective cohort study. METHODS: We recruited 86 injured and 64 uninjured youth (similar age, sex, sport). Knee-related QOL was assessed with the Knee injury and Osteoarthritis Outcome Score (KOOS) QOL subscale. Linear mixed models (95% confidence interval [CI]; clustered on sex and sport) compared KOOS QOL between study groups over the study period, considering sex-based differences. We also explored the association of injury type (anterior cruciate ligament [ACL]/meniscus injury or other), knee extensor strength (dynamometry), moderate-to-vigorous physical activity (accelerometer), intermittent knee pain (Intermittent and Constant Osteoarthritis Pain [ICOAP] measure), and fear of reinjury (17-item Tampa Scale of Kinesiophobia) with knee-related QOL. RESULTS: Participant median (range) age was 16.4 (10.9-20.1) years, 67% were female, and 56% of injuries were ACL ruptures. Injured participants had lower mean KOOS QOL scores at baseline (-61.05; 95% CI: -67.56, -54.53), 6-month (-41.37; 95% CI: -47.94, -34.80), and 12-month (-33.34; 95% CI: -39.86, -26.82) follow-up, regardless of sex. Knee extensor strength (6- and 12-month follow-up), moderate-to-vigorous physical activity (12-month follow-up), and ICOAP (all time points) were associated with KOOS QOL in injured youth. Additionally, having an ACL/meniscus injury and higher Tampa Scale of Kinesiophobia scores were associated with worse KOOS QOL in injured youth. CONCLUSION: Youth with a sport-related knee injury have significant, persistent knee-related QOL deficits at 12-month follow-up. Knee extensor strength, physical activity, pain, and fear of reinjury may contribute to knee-related QOL. JOSPT 2023;53(8):1-10. Epub: 20 June 2023. doi:10.2519/jospt.2023.11611.

Is Physical Activity-Related Self-Efficacy Associated with Moderate to Vigorous Physical Activity and Sedentary Behaviour among Ambulatory Children with Cerebral Palsy?

Purpose: To determine how physical activity-related self-efficacy is associated with physical activity and sedentary behaviour time among ambulatory children with cerebral palsy (CP). Method: Children with CP, Gross Motor Function Classification System (GMFCS) Levels I-III (N = 26; aged 9-18 y), completed the task self-efficacy component of a self-efficacy scale and wore Actigraph GT3X+ accelerometers for 5 days. Correlations (Pearson and Spearman's rank-order; α = 0.050) were conducted to evaluate the relationships among age, GMFCS level, self-efficacy, and both daily moderate-to-vigorous physical activity (MVPA) and sedentary time. Linear regression models were used to determine the relationships among the independent variables and MVPA and sedentary time. Results: Self-efficacy was positively associated with MVPA time (r = 0.428, p = 0.015) and negatively correlated with sedentary time (r = -0.332, p = 0.049). In our linear regression models, gross motor function (ß = -0.462, p = 0.006), age (ß = -0.344, p = 0.033), and self-efficacy (ß = 0.281, p = 0.080) were associated with MVPA time (R2 = 0.508), while GMFCS level (ß = 0.439, p = 0.003) and age (ß = 0.605, p < 0.001) were associated with sedentary time (R2 = 0.584). Conclusions: This research suggests that self-efficacy, age, and gross motor function are associated with MVPA in children with CP. Additional research is needed to confirm these findings and further explore the influence of self-efficacy on sedentary behaviour.

Objectif : déterminer l'association entre l'autoefficacité liée à l'activité physique et la durée de l'activité et du comportement sédentaire chez les enfants ambulatoires ayant la paralysie cérébrale (PC). Méthodologie : des enfants ayant la PC âgés de 9 à 18 ans (N = 26) présentant les niveaux I à III du système de classification de la fonction motrice globale (GMFCS) ont effectué l'élément d'autoefficacité de l'échelle d'autoévaluation et ont porté des accéléromètres Actigraph GT3X+ pendant cinq jours. Les chercheurs ont établi des corrélations (hiérarchie de Pearson et Spearman; α = 0,050) pour évaluer les relations entre l'âge, le niveau de GMFCS, l'autoefficacité et à la fois l'activité physique modérée à vigoureuse (APMV) et à la durée de la sédentarité. Ils ont utilisé les modèles de régression linéaire pour déterminer la relation entre, d'une part, les variables indépendantes et, d'autre part, l'APMV et la sédentarité. Résultats : l'autoefficacité était associée de manière positive au temps d'APMV (r = 0,428, p = 0,015) et de manière négative avec la durée de sédentarité (r = ­0,332, p = 0,049). Dans les modèles de régression linéaire des chercheurs, la fonction motrice globale (ß = ­0,462, p = 0,006), l'âge (ß = ­0,344, p = 0,033) et l'autoefficacité (ß = 0,281, p = 0,080) étaient associés à la durée de l'APMV (R2 = 0,508), mais le niveau du GMFCS (ß = 0,439, p = 0,003) et l'âge (ß = 0,605, p < 0,001) étaient corrélés avec la durée de sédentarité (R2 = 0,584). Conclusions : selon la présente recherche, l'autoefficacité, l'âge et la fonction motrice globale sont liées à l'APMV chez les enfants ayant la PC. D'autres recherches devront être réalisées pour confirmer ces observations et explorer plus à fond l'influence de l'autoefficacité sur le comportement sédentaire.

Stroke survivors partner in research: a case example of collaborative processes.

The Canadian Strategy for Patient-Oriented Research supports the inclusion of patients as partners throughout the research process. Purposeful and meaningful engagement of patient partners after stroke can present unique challenges due to the potential impacts on cognition, communication, or mobility. The purpose of this paper is to provide a case example of working together with three individuals who bring their post-stroke lived experience, including one person with aphasia, from study design through to dissemination. The designed and executed qualitative research was the purpose of this collaboration; this paper describes the collaborative process rather than the outcomes of the original research. The Strategy for Patient-Oriented Research Patient Engagement Framework was followed to engage the patient partners fully as part of the research team. Patient partners were involved at regularly scheduled team meetings and provided guidance on key aspects of project design and decision-making. The patient partners provided robust and important contributions to many aspects of the research, including shaping interview questions, assisting with thematic analysis, and contributing to the dissemination of research findings. Effective team dynamics were fostered by focusing on the value of the lived experience knowledge, using best-practice communication strategies, as well as taking time for relationship-building and story sharing. With appropriate support and guidance, the individuals who have experienced stroke were valuable contributing members of our research team.

Whenever possible, including patients as partners in the research process can improve the quality of the research and the relevance of the results. Sometimes, there can be challenges when engaging people with lived experience in health research. For example, after a stroke, some patients can have trouble moving, thinking, or speaking. The purpose of this paper is to describe the processes used by our research team, comprised of two researchers and three patient partners with lived experience who had knowledge and insights into surviving a moderate to severe stroke. The research was a graduate student project exploring what patients think of physical therapy tests and measures used post-stroke. This article describes the process, rather than the outcomes of that research. We collaborated through virtual meetings, which were held every time decisions about the research had to be made or where feedback was required. The patient partners improved the interview question guide, helped to analyze the data, and helped to communicate the research findings. We found several strategies that helped us to be successful, including focusing on the value of the patient perspective and insights, taking time to build relationships, and allowing time to share stories. We also took special care to follow recommendations about communication to make sure that all the patient partners understood the project aim and activities that we were working on together. We feel this paper shows how patients who have had a stroke can collaborate as valued members of health research teams.

Preliminary efficacy of the "SitLess with MS" intervention for changing sedentary behaviour, symptoms, and physical performance in multiple sclerosis.

PURPOSE: People with multiple sclerosis (MS) sit (i.e., are sedentary) more than peers. We examined the preliminary efficacy of an internet-based intervention that focuses on sitting less and moving more for changing sedentary behaviour outcomes, symptoms, QOL, and physical performance in adults with MS. METHODS: Persons with mild-to-moderate disability from MS took part in a 15-week pre-post trial. Outcomes including sedentary behaviour, representative symptoms (e.g., fatigue, pain), QOL and physical performance measures (e.g., walking speed) were measured at three time points: pre-post intervention and at follow-up. An unstructured linear mixed-effects model was used to determine change over time per outcome. RESULTS: Forty-one persons with MS participated (age 50 ± 10.3 years). There were significant reductions in total sedentary time (d = 0.34) and the number of long (≥30 min) bouts of sedentary time (d = 0.39) post-intervention. All symptoms and physical performance measures were significantly improved following the intervention, with effects sizes greatest for fatigue (d = 0.61) and depression (d = 0.79). Changes were maintained during the 7-week follow-up, except for all sedentary behaviour outcomes and sleep quality. Cognition did not change. CONCLUSIONS: This study provides preliminary support for the efficacy of an intervention focused on sitting less and moving more for improving symptoms in adults with MS.IMPLICATIONS FOR REHABILITATIONThis research provides preliminary evidence that an intervention aimed at reducing sedentary behaviour and increasing light intensity activity throughout the day can have an impact.Fatigue, depression and anxiety, symptoms frequently encountered by people with MS, showed the greatest improvement following the intervention.Weekly coaching sessions including discussions about results from activity monitoring provided motivation for participants. TRIAL REGISTRATION: The "SitLess with MS" feasibility study was registered at ClinicalTrials.gov Trial Registration Number: NCT03136744. Date of registration was 2 May 2017.

Evaluation of a balance and mobility program for older adults at risk of falling: a mixed methods study.

RATIONAL, AIMS, AND OBJECTIVES: The FallProof Balance and Mobility Program is a multifactorial fall prevention intervention that targets intrinsic risk factors such as muscle strength, balance, gait, and posture. Using mixed methods, we evaluated the implementation of the program for older adults at high risk of falling in the community. METHODS: A pre-post program evaluation and semi-structured interviews were used to evaluate FallProof Balance and Mobility Program offered to older adults who were recurrent fallers. Over a 1-year period, the 12-week program was offered five times. Feasibility, acceptability, and outcome evaluation along with semi-structured interviews were done. Over the course of the evaluation, participants were evaluated three times (baseline, 12, and 16 weeks). RESULTS: Of the 19 participants, who enrolled in the program, 16 completed the program and 12 attended at least 80% of the classes. Fourteen participants had mildly impaired cognition (Montreal Cognitive Assessment <26). Large gains (effect size 0.90) were seen with self-management (Partner-in-Health Scale). Participants were very satisfied with the program. Three themes emerged from the semi-structured interviews: (a) fall-related benefits, (b) variety of activities and motivating instructors, and (c) deterrents to participation. CONCLUSION: Findings provided insights into pragmatic issues of implementing a balance and mobility program for older adults at risk of falling. The FallProof program was found to be feasible and acceptable in a small cohort of older adults from the community.

Early indicators of cardiovascular disease are evident in children and adolescents with cerebral palsy.

BACKGROUND: Cardiovascular disease (CVD) is a leading cause of early mortality among young adults with cerebral palsy. While low physical activity in childhood has been hypothesized as a potential contributor to increased CVD risk in early adulthood, little is known about timing of vascular disease progression and the presence of subclinical atherosclerosis has not been extensively evaluated in children with cerebral palsy. OBJECTIVE: The aim of this study was to determine if measures of vascular structure and function are different between children and adolescents with and without cerebral palsy. METHODS: In this cross-sectional study, we measured carotid intima-media thickness (CIMT), and brachial artery flow-mediated dilation (FMD) of children with and without cerebral palsy. Group means for CIMT and brachial artery FMD absolute (FMDA) and percent of relative change (FMDR%) were compared using Wilcoxon rank-sum tests. RESULTS: A total of 26 children and adolescents with cerebral palsy (46.1% girls, mean age = 15.0 ± 2.0 years) and 19 controls (68.4% girls, mean age = 13.3 ± 2.6 years) participated. Children with cerebral palsy had significantly greater average CIMT (0.43 ± 0.02 mm) than children without cerebral palsy (0.41 ± 0.01 mm, p = 0.04), and lower FMDA (0.16 ± 0.15 mm vs. 0.29 ± 0.20 mm; respectively, p = 0.03). CONCLUSIONS: Children and adolescents with cerebral palsy may exhibit impairments in vascular structure and function which represent an increased risk of premature atherosclerosis compared to children without cerebral palsy. Additional research to identify risk factors specific to children with cerebral palsy that would support the development of effective screening processes for early identification would enable clinicians to implement targeted preventive strategies.

Balancing Access with Technology: Comparing In-Person and Telerehabilitation Berg Balance Scale Scores among Stroke Survivors.

Purpose: Stroke survivors living in rural and remote communities experience challenges in accessing specialized rehabilitation services. Access to balance assessment after stroke is an essential aspect of the physiotherapy assessment. Telerehabilitation (TRH) can eliminate access disparities; however, adoption into practice has been limited. Our primary objective was to examine agreement between Berg Balance Scale (BBS) scores obtained through TRH and those obtained through traditional in-person assessment of community-dwelling individuals with stroke. Method: Two raters administered the BBS to 20 community-dwelling individuals with stroke, using both TRH and traditional in-person approaches. The order of assessments and rater assignment was randomized. Interrater reliability between the methods was assessed using Krippendorff's α reliability estimate. A survey was then administered to examine the participants' perceptions of the two means of assessment. Results: Excellent interrater agreement was found between TRH and in-person assessment (κ = 0.97; 95% CI: 0.96, 0.99), and responses regarding patients' perceived hearing and understanding of instructions as well as perceived safety were comparable. In addition, the vast majority of participants agreed or strongly agreed that they would use TRH for future physiotherapy sessions. Conclusions: The results of this study support administration of the BBS using TRH technology; this could improve access to balance assessment for stroke survivors in rural and remote communities.

Objectif : les survivants d'un accident vasculaire cérébral (AVC) qui vivent en région rurale ou éloignée éprouvent de la difficulté à accéder à des services de réadaptation spécialisés. L'accès à une évaluation de l'équilibre après un AVC est un aspect essentiel de l'évaluation physiothérapique. La téléréadaptation peut éliminer les disparités d'accès, mais sa mise en pratique est limitée. Les chercheurs se sont donné comme objectif principal d'examiner la concordance entre les scores de l'échelle d'évaluation de l'équilibre de Berg (ÉÉÉB) obtenus par transmission vidéo grâce à la téléréadaptation et ceux obtenus par les évaluations physiques habituelles chez des personnes victimes d'un AVC habitant dans la communauté. Méthodologie : deux évaluateurs ont mesuré le score de la BBS chez 20 personnes ayant subi un AVC habitant dans la communauté, à la fois par la téléréadaptation et par l'approche physique habituelle. Ils ont établi l'ordre d'évaluation et l'affectation des évaluateurs au hasard, ont déterminé la fiabilité interévaluateur des deux méthodes au moyen du coefficient alpha de Krippendorff et ont ensuite réalisé un sondage pour connaître les perceptions de participants à l'égard des deux évaluations. Résultats : les chercheurs ont constaté une excellente concordance interévaluateur entre la téléréadaptation et l'évaluation physique (κ = 0,97; IC à 95 % : 0,96, 0,99), et les patients ont entendu et compris les directives et se sont sentis en sécurité selon un ordre de perception comparable. De plus, la grande majorité d'entre eux ont convenu ou fortement convenu qu'ils utiliseraient la vidéoconférence pour leurs futures séances de physiothérapie. Conclusion : les résultats de cette étude appuient l'utilisation de l'ÉÉÉB en téléréadaptation, ce qui pourrait améliorer l'accès des survivants d'un AVC qui vivent en région rurale ou éloignée à l'évaluation de l'équilibre.

Reliability of the performance and safety scores of the wheelchair skills test version 4.1 for manual wheelchair users.

OBJECTIVE: To evaluate the interrater, intrarater, and test-retest reliability of the total performance and safety scores of the Wheelchair Skills Test version 4.1 (WST 4.1) for manual wheelchairs operated by adult wheelchair users. DESIGN: Cohort study. SETTING: University research setting. PARTICIPANTS: People (N=11) who used manual wheelchairs for community locomotion. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Participants were videotaped as they completed the WST 4.1 (30 skills) on 2 separate occasions 1 to 2 weeks apart. Subsequently, raters scored the WST 4.1 from the video recordings and each participant received a total score for performance and safety. Using those scores, interrater, intrarater, and test-retest reliability were determined by using intraclass correlation coefficients (ICCs). Percentages of agreement between raters for individual skills also were calculated. RESULTS: Mean ± SD overall WST 4.1 scores for performance and safety were 80.1%±8.5% and 98.0%±2.8%. ICCs for the interrater, intrarater, and test-retest reliability of the performance component were .855, .950, and .901 (P<.001). Safety component ICC scores were .061 (P=.243), .228 (P=.048), and .254 (P=.041). Percentages of agreement between raters for each test item for both the performance and safety scales ranged from 68% to 100%. CONCLUSIONS: Reliability of the performance component of the WST 4.1 was excellent, whereas ICCs for the safety component indicated only slight to fair agreement, probably because of the low variability in safety scores. Additional study is needed to further evaluate the reliability of the safety component with a larger and more diverse sample group.

Using Intervention Mapping to develop and implement a home-based sedentary behavior change intervention after stroke.

Prolonged sedentary behavior is a problem immediately following a stroke and it persists from the acute to chronic phases of recovery. Frequently interrupting sedentary time might help to mitigate the associated detrimental health consequences. The purpose of this article was to describe the process followed in the systematic development and implementation of a theory- and home-based sedentary behavior change intervention for people with stroke. The Intervention Mapping protocol was used to design, develop and implement a STand Up Frequently From Stroke (STUFFS) program aimed at reducing prolonged sedentary behavior after stroke. A qualitative inquiry with people with stroke (n = 13) informed the development of the intervention. The systematic approach followed in the development process including the theoretical basis, content development, and evaluation planning were described. Program reception was assessed using thematic content analysis of exit-interview data (n = 25). The 8-weeks STUFFS intervention is a home-based sedentary behavior change program that provides education about the risks of prolonged sedentary behavior and facilitates behavior change, including the use of motivational tools to empower people with stroke to reduce sedentary behavior. The program was well-received and acceptable to people with stroke (89% satisfaction). This article provides information that furthers knowledge about theory-based strategies to reduce sedentary behavior in the home environment after stroke and facilitates implementation of this type of intervention.
