Experiential Aspects of Participation in Employment and Mobility for Adults With Physical Disabilities: Testing Cross-Sectional Models of Contextual Influences and Well-Being Outcomes.

OBJECTIVE: To use structural equation modeling to test research- and theory-informed models of potential predictors and outcomes of subjective experiences of employment and mobility participation in a national sample of people with physical disabilities. DESIGN: Cross-sectional survey. SETTING: Canada. PARTICIPANTS: English or French-speaking adults with a physical impairment affecting mobility and restricting activities or participation, and who participated in employment (n=457) or mobility (n=711) life domains. INTERVENTIONS: N/A. MAIN OUTCOME MEASURES: Participants completed standardized measures of perceived health, and employment-specific and/or mobility-specific measures of perceived abilities, social support, accessibility and policies (predictor variables); the Measure of Experiential Aspects of Participation (MeEAP) in employment and/or mobility; and standardized measures of emotional well-being, social well-being and life satisfaction (outcome variables). RESULTS: Analyses using structural equation modeling showed that in both employment and mobility domains, perceived health, abilities, social support, and accessibility were positively related to experiential aspects of participation. Participation experiences were positively related to social well-being, emotional well-being, and life satisfaction. CONCLUSIONS: Results support and extend current theorizing on participation experiences among adults with physical disabilities. Intrapersonal and environmental factors may play a role in optimizing participation experiences in employment and mobility which, in turn, may lead to better well-being and life satisfaction. These results emphasize the importance of conceptualizing participation from an experiential perspective and provide a basis for advancing theory and practice to understand and improve the participation experiences and well-being of adults living with physical disabilities.

Effectiveness of the miWe Simulator Training on Powered Wheelchair-driving Skills: A Randomized Controlled Trial.

OBJECTIVES: To evaluate the effectiveness of a home-based simulator training, in comparison with a videogame-based training, in terms of powered wheelchair driving skills, skills use in a real-world setting, and driving confidence. DESIGN: Single-blinded randomized controlled trial. SETTING: Community. PARTICIPANTS: New powered wheelchair users (N=47) randomly allocated to simulator group (n=24, 2 drop-out) and control group (n=23, 3 drop-out). INTERVENTIONS: The miWe wheelchair simulator (simulator group) or a kart driving videogame (control group) was setted-up at participants' homes (computer + joystick). They were instructed to use it at least 20 minutes every 2 days, during a period of 2 weeks. PRIMARY OUTCOME MEASURE(S): Assessments were done at baseline (T1) and post-training (T2) using the Wheelchair Skills Test Questionnaire (WST-Q, version 4.1), Wheelchair Confidence Scale (WheelCon), Assistive Technology Outcomes Profile for Mobility, and Life-Space Assessment (LSA). The time necessary to complete 6 WST tasks was measured with a stopwatch. RESULTS: Participants of the simulator group significantly increased their WST-Q capacity score at T2 by 7.5% (P<.05), whereas the control group remained at the same score (P=.218). Participants of both groups rolled backward and went through a door significantly faster at T2 (P=.007; P=.016), but their speed did not change for the other skills. The WheelCon score significantly increased after training (+4% for the control group and +3.5% for the simulator group, P=.001). There was no T1-T2 difference between groups for the WST-Q performance scores (P=.119), the ATOP-Activity (P=.686), the ATOP-Participation scores (P=.814), and the LSA score (P=.335). No adverse events or side effects were reported during data collection or training. CONCLUSIONS: Participants of both groups improved some skills and their wheelchair driving confidence. The simulator training group also demonstrated a modest post-training gain in their WST-Q capacity, but more studies would be needed to explore the long-term effects of the McGill immersive wheelchair simulator (miWe) simulator on driving skills.

A systematic review of the determinants of implementation of a locomotor training program using a powered exoskeleton for individuals with a spinal cord injury.

BACKGROUND: Wearable powered exoskeletons represent a promising rehabilitation tool for locomotor training in various populations, including in individuals with a spinal cord injury. The lack of clear evidence on how to implement a locomotor powered exoskeleton training program raises many challenges for patients, clinicians and organizations. OBJECTIVE: To report determinants of implementation in clinical practice of an overground powered exoskeleton locomotor training program for persons with a spinal cord injury. DATA SOURCES: Medline, CINAHL, Web of Science. STUDY SELECTION: Studies were included if they documented determinants of implementation of an overground powered exoskeleton locomotor training program for individuals with spinal cord injury. DATA EXTRACTION: Eligible studies were identified by two independent reviewers. Data were extracted by one reviewer, based on constructs of the Consolidated Framework for Implementation Research, and validated by a second reviewer. RESULTS: Sixty-three articles were included. 49.4% of all determinants identified were related to the intervention characteristics, 29.6% to the individuals' characteristic and 13.5% to the inner setting. Recurrent barriers identified were the high prevalence of adverse events (e.g., skin issues, falls) and device malfunctions. Adequate training for clinicians, time and resource available, as well as discussion about patients' expectations were identified as facilitators. CONCLUSIONS: Powered exoskeleton training is a complex intervention. The limited information on the context and the implementation process domains may represent a barrier to a successful transition from knowledge to action.

Efficient Self-Attention Model for Speech Recognition-Based Assistive Robots Control.

Assistive robots are tools that people living with upper body disabilities can leverage to autonomously perform Activities of Daily Living (ADL). Unfortunately, conventional control methods still rely on low-dimensional, easy-to-implement interfaces such as joysticks that tend to be unintuitive and cumbersome to use. In contrast, vocal commands may represent a viable and intuitive alternative. This work represents an important step toward providing a viable vocal interface for people living with upper limb disabilities by proposing a novel lightweight vocal command recognition system. The proposed model leverages the MobileNet2 architecture, augmenting it with a novel approach to the self-attention mechanism, achieving a new state-of-the-art performance for Keyword Spotting (KWS) on the Google Speech Commands Dataset (GSCD). Moreover, this work presents a new dataset, referred to as the French Speech Commands Dataset (FSCD), comprising 4963 vocal command utterances. Using the GSCD as the source, we used Transfer Learning (TL) to adapt the model to this cross-language task. TL has been shown to significantly improve the model performance on the FSCD. The viability of the proposed approach is further demonstrated through real-life control of a robotic arm by four healthy participants using both the proposed vocal interface and a joystick.

Service delivery and programing adaptations for individuals with disabilities by municipalities and non-profit organizations during the COVID pandemic.

Municipalities and nonprofit organizations play a major role in administrating services that support individuals with disabilities. The purpose of this study was to explore how these organizations responded to the COVID-19 pandemic in regards to service delivery and programming for people with disabilities. This qualitative interpretative description study used semi-structured individual interviews for data collection. Recordings of the interviews were transcribed. Then the transcripts were analyzed qualitatively for themes following an inductive approach. Twenty-six individuals working for nonprofit organization or municipalities participated in the study. Six themes were identified: doing more with less; adapting rather than creating new services; ongoing consultation with stakeholders; feeling successful at adapting the services; being innovative with fundraising and embracing radical change. Flexibility and iterative user-centered approach appeared to be common coping strategies. Remote services were privileged to adapt service delivery during the COVID-19 pandemic.

Evaluation of pediatric-specific resources to support utilization of the Wheelchair Skills Training Program by the users of the resources: a descriptive qualitative study.

BACKGROUND: Children's ability to engage in meaningful activities is positively influenced by their ability to move independently. Preliminary evidence in children suggests that wheelchair skills training improves wheelchair skills, which are important for independent mobility. The Wheelchair Skills Training Program is a standardized program to teach wheelchair skills. However, it is underutilized in pediatric rehabilitation settings. To increase its utilization, 3 pediatric-specific Wheelchair Skills Training Program resources related to indoor skills were developed (i.e., a storybook, four instructional posters, and a training workbook). This study aimed to describe occupational therapists' (OTs) and pediatric manual wheelchair users' (PMWUs) perceived satisfaction with the storybook, instructional posters and training workbook, and to explore their perceptions regarding the usability, relevance, and feasibility of these resources in pediatric rehabilitation settings. METHODS: A descriptive qualitative design was used. Convenience samples of OTs and PMWUs were recruited in a rehabilitation center and affiliated schools. A focus group with OTs and semi-structured interviews with PMWUs were conducted by videoconference to obtain participants' feedback on the resource prototypes and suggestions for improvement. Data were deductively analyzed using the Framework method. RESULTS: Eight OTs and 5 PMWUs expressed general satisfaction with the resources, describing them as usable, relevant, and feasible to integrate into wheelchair skills training with novice wheelchair users and younger children. All OTs and 3 PMWUs expressed the desire to use the resources for wheelchair skills training. Two PMWUs perceived the resources were not relevant to them because they already mastered the skills. The participants suggested minor modifications for improving the resources (e.g., more action in the story, increased precision of illustrations related to the characters' position in the wheelchair). CONCLUSION: OTs and PMWUs were satisfied with the resources, perceiving them to be applicable for training wheelchair skills among young children and novice wheelchair users. The resources represent a concrete solution to facilitate the use of the Wheelchair Skills Training Program in pediatric rehabilitation settings. Additional resources are needed to better reach older and more experienced PMWUs (i.e., of intermediate and advanced skill levels).

Criterion validity of ActiGraph monitoring devices for step counting and distance measurement in adults and older adults: a systematic review.

BACKGROUND: Wearable activity monitors such as ActiGraph monitoring devices are widely used, especially in research settings. Various research studies have assessed the criterion validity of ActiGraph devices for step counting and distance estimation in adults and older adults. Although several studies have used the ActiGraph devices as a reference system for activity monitoring, there is no summarized evidence of the psychometric properties. The main objective of this systematic review was to summarize evidence related to the criterion validity of ActiGraph monitoring devices for step counting and distance estimation in adults and/or older adults. METHODS: Literature searches were conducted in six databases (Medline (OVID), Embase, IEEExplore, CINAHL, Engineering Village and Web of Science). Two reviewers independently conducted selection, a quality analysis of articles (using COSMIN and MacDermid's grids) and data extraction. RESULTS: This review included 21 studies involving 637 participants (age 30.3 ± 7.5 years (for adults) and 82.7 ± 3.3 years (for older adults)). Five ActiGraph devices (7164, GT1M, wGTX +, GT3X +/wGT3X + and wGT3X - BT) were used to collect data at the hip, wrist and ankle to assess various walking and running speeds (ranging from 0.2 m/s to 4.44 m/s) over durations of 2 min to 3 days (13 h 30 mins per day) for step counting and distance estimation. The ActiGraph GT3X +/wGT3X + and wGT3X - BT had better criterion validity than the ActiGraph 7164, wGTX + and GT1M according to walking and running speeds for step counting. Validity of ActiGraph wGT3X + was good for distance estimation. CONCLUSION: The ActiGraph wGT3X - BT and GT3X +/wGT3X + have good criterion validity for step counting, under certain conditions related to walking speeds, positioning and data processing.

Using photovoice to increase social inclusion of people with disabilities: Reflections on the benefits and challenges.

The aim of this study was to understand the mobility experiences of mobility device users regarding the environmental and social barriers and facilitators in their community and to discuss the benefits and challenges of using photovoice, as a participatory methodology, to increase social participation for people with disabilities. Photovoice was used with mobility device users (n = 70) in two different locations in Canada. The participants took pictures for two weeks and then participated in individual interviews and focus group sessions to discuss their photographs. The participants took over 1,000 pictures that were grouped into five themes around social participation and accessibility. They chose the most illustrative pictures to share in an exhibit to create a dialogue with different stakeholders. Using photovoice offered many benefits such as allowing the participants to be equal partners of the research and made their voices heard, but also presented disability and study-related challenges.

Development and Validation of Open-Source Activity Intensity Count and Activity Intensity Classification Algorithms from Raw Acceleration Signals of Wearable Sensors.

BACKGROUND: A popular outcome in rehabilitation studies is the activity intensity count, which is typically measured from commercially available accelerometers. However, the algorithms are not openly available, which impairs long-term follow-ups and restricts the potential to adapt the algorithms for pathological populations. The objectives of this research are to design and validate open-source algorithms for activity intensity quantification and classification. METHODS: Two versions of a quantification algorithm are proposed (fixed [FB] and modifiable bandwidth [MB]) along with two versions of a classification algorithm (discrete [DM] vs. continuous methods [CM]). The results of these algorithms were compared to those of a commercial activity intensity count solution (ActiLife) with datasets from four activities (n = 24 participants). RESULTS: The FB and MB algorithms gave similar results as ActiLife (r > 0.96). The DM algorithm is similar to a ActiLife (r ≥ 0.99). The CM algorithm differs (r ≥ 0.89) but is more precise. CONCLUSION: The combination of the FB algorithm with the DM results is a solution close to that of ActiLife. However, the MB version remains valid while being more adaptable, and the CM is more precise. This paper proposes an open-source alternative for rehabilitation that is compatible with several wearable devices and not dependent on manufacturer commercial decisions.

Influence of Peer-led Wheelchair Training on Wheelchair Skills and Participation in Older Adults: Clinical Outcomes of a Randomized Controlled Feasibility Trial.

OBJECTIVE: To estimate treatment effect size of a peer-led Wheelchair Self-Efficacy Enhanced for Use (WheelSeeU) program on objective wheelchair skills (primary); and on perceived wheelchair skills capacity and performance, wheelchair use self-efficacy, satisfaction with participation, life-space mobility, and participation frequency (secondary); and to evaluate retention 6 months later (secondary). DESIGN: Randomized controlled trial. SETTING: Rehabilitation centers and communities. PARTICIPANTS: Community-living older adults (N=40). INTERVENTION: WheelSeeU comprised six 90-minute peer-led sessions of customized training (in pairs) according to participants' goals. A support-trainer provided spotting. The control group comprised six 90-minute professional-led didactic information sessions (in pairs). MAIN OUTCOME MEASURES: The Wheelchair Skills Test (WST), Wheelchair Skills Test Questionnaire (WST-Q), Wheelchair Use Confidence Scale for Manual Wheelchair Users-Short Form (WheelCon-M-SF), Wheelchair Outcomes Measure (WhOM), Life-Space Mobility (LSA), and Late Life Function and Disability Index (LLFDI) were collected at baseline (T1), postintervention (T2), and 6 months postintervention (T3). RESULTS: Of 121 screened, 39 individuals did not meet the inclusion criteria and 41 declined to participate. Forty participants (64.5 years of age; 60% men) were randomized, 38 completed the intervention, and 35 completed T3 assessments. There were no adverse effects. WheelSeeU did not have a statistically significant greater effect on objective WST (primary) or WST-Q capacity, WheelCon, LSA, and LLFDI at T2 compared to the control group. Effect sizes were statistically significant and large for WST-Q performance (Cohen's d=0.72) and the WhOM (Cohen's d=0.82) at T2, and effects were retained at T3. CONCLUSION: Compared to an active control group, WheelSeeU did not have a greater effect on wheelchair skills capacity. However, WheelSeeU should not be prematurely dismissed as an approach to potentially improve wheelchair skills performance and satisfaction with participation in meaningful activities. Sex and depression are important when designing interventions for older adults.

Psychometric properties of the Community Integration Questionnaire: a systematic review of five populations.

OBJECTIVES: This systematic review documents the content and the quality of the psychometric evidence concerning the utilization of the Community Integration Questionnaire for individuals living with a disability other than a traumatic brain injury. DATA SOURCES: Medline, Embase, CINAHL, OTseeker and PsycINFO (searched from inception to June 2019). REVIEW METHODS: Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used for conducting and reporting this review. Studies that investigated at least one psychometric property of the Community Integration Questionnaire for individuals living with a disability other than traumatic brain injury were included. Data extraction and critical methodological appraisal of the articles (MacDermid checklist, COnsensus-based Standards for the selection of health Measurement INstruments checklist) were independently performed and validated by the first two authors. RESULTS: Ten studies representing 3000 individuals met the inclusion criteria. Five populations were documented. There are positive and trustable data regarding internal consistency for adults living with multiple sclerosis, spinal cord injury or burns and in mixed samples (α = 0.71-0.84). Construct validity is fairly documented for adults living with multiple sclerosis or aphasia and in mixed samples. Test-retest reliably is acceptable for adults living with multiple sclerosis (intraclass correlation coefficient = 0.91-0.97) as well as responsiveness (area under the receiver operating characteristic curve = 0.81). Other psychometric properties could not be demonstrated sufficiently solid. CONCLUSION: Many psychometric properties of the Community Integration Questionnaire are still poorly evaluated for adults living with a disability other than a traumatic brain injury. However, promising data have been documented in each population included in this review.

Extent to Which Caregivers Enhance the Wheelchair Skills Capacity and Confidence of Power Wheelchair Users: A Cross-Sectional Study.

OBJECTIVE: To test the hypothesis that caregivers enhance the wheelchair skills capacity and confidence of the power wheelchair users to whom they provide assistance, and to describe the nature of that assistance. DESIGN: Multicenter cross-sectional study. SETTING: Rehabilitation centers and communities. PARTICIPANTS: Participants (N=152) included caregivers (n=76) and wheelchair users (n=76). INTERVENTIONS: None. MAIN OUTCOME MEASURES: Version 4.3 of the Wheelchair Skills Test (WST) and the Wheelchair Skills Test-Questionnaire (WST-Q). For each of the 30 individual skills, we recorded data about the wheelchair user alone and in combination (blended) with the caregiver. RESULTS: The mean total WST capacity scores ± SD for the wheelchair users alone and blended were 78.1%±9.3% and 92.4%±6.1%, respectively, with a mean difference of 14.3%±8.7% (P<.0001). The mean WST-Q capacity scores ± SD were 77.0%±10.6% and 93.2%±6.4%, respectively, with a mean difference of 16.3%±9.8% (P<.0001). The mean WST-Q confidence scores ± SD were 75.5%±12.7% and 92.8%±6.8%, respectively, with a mean difference of 17.5%±11.7% (P<.0001). The mean differences corresponded to relative improvements of 18.3%, 21.0%, and 22.9%, respectively. The nature and benefits of the caregivers' assistance could be summarized in 7 themes (eg, caregiver provides verbal support [cueing, coaching, reporting about the environment]). CONCLUSIONS: Caregivers significantly enhance the wheelchair skills capacity and confidence of the power wheelchair users to whom they provide assistance, and they do so in a variety of ways. These findings have significance for wheelchair skills assessment and training.

Visuo-locomotor control in persons with spinal cord injury in a manual or power wheelchair for direction change and obstacle circumvention.

Many individuals, such as persons with spinal cord injury (SCI), rely on wheeled locomotion involving manual (MWC) or power (PWC) wheelchairs to navigate their environments. Yet, visuo-locomotor control underlying WC navigation in experienced users is not well understood. The objective of this study was to compare the visuo-locomotor control between MWC and PWC in individuals with SCI while changing direction and circumventing an obstacle. Participants with SCI using a MWC (n = 12, 38.5 ± 10.7 years) or a PWC (n = 10, 47.8 ± 8.6 years) were asked to maneuver their chair straight ahead, while changing direction 45° to the right, and while circumventing an obstacle to the right, all at self-selected speeds. Speed, minimal clearance, point of deviation, temporal body and WC coordination, relative timing of segment rotations and visual behavior were analyzed. There was no main effect of group for speed, clearance and point of deviation. During direction change, the head always led body and wheelchair reorientation while an "en bloc" strategy was used for circumventing obstacle for both groups. In straight-ahead locomotion, participants predominantly fixed their gaze on the end target. During direction change and obstacle circumvention, participants fixated more on the future path and the obstacle for both WC modes. Overall, specific gaze behavior depended on environmental demands. While MWC and PWC users adopt similar navigational strategies and visuo-locomotor coordination while changing direction and circumventing obstacle, there were some differences in the amount of head rotation that could be related to a counter-movement used more by PWC users.

Ultrasonographic Measures of the Acromiohumeral Distance and Supraspinatus Tendon Thickness in Manual Wheelchair Users With Spinal Cord Injury.

OBJECTIVES: (1) To evaluate the reliability of ultrasonographic measures of the acromiohumeral distance (AHD) in shoulder positions linked to wheelchair propulsion in manual wheelchair users (MWUs) with spinal cord injury (SCI) and able-bodied individuals; (2) to compare ultrasonographic measures of AHD, supraspinatus tendon thickness, and occupation ratio between MWUs with SCI with and without shoulder pain (rotator cuff [RC] tendinopathy); and (3) to compare these ultrasonographic measures between MWUs with SCI and able-bodied individuals. DESIGN: Cross-sectional study. SETTING: Rehabilitation centers. PARTICIPANTS: Three groups of participants (N=95; aged between 18 and 60y) were recruited within a convenience sample: objective 1: 16 MWUs with SCI (mean age, 43±9y; height, 172±13 cm, weight, 84±10 kg) and 16 able-bodied individuals (mean age, 28±9y; height, 176±11 cm, weight, 72±12 kg); objectives 2 and 3: 37 MWUs with SCI (17 with [mean age, 47±11y; height, 172±14 cm, weight, 68±11 kg] and 20 without [mean age, 45±10y; height, 172±15 cm, weight, 84±30 kg] RC tendinopathy) and 26 able-bodied individuals (mean age, 31±5y; height, 175±12 cm; weight, 89±14 kg). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: AHD, supraspinatus tendon thickness, and occupation ratio of the supraspinatus tendon measured using ultrasound imaging systems. RESULTS: (1) Excellent intra- and interrater reliability of AHD was obtained in each arm position (intraclass correlation coefficient>.85); (2) MWUs without shoulder pain have thicker tendon than do MWUs with RC tendinopathy; and (3) a significant Group × Position interaction was found for AHD measures when comparing MWUs with SCI with able-bodied individuals (greater AHD at the end of the push phase for MWUs with SCI). A thicker tendon and a higher occupation ratio were also found in MWUs with SCI than in able-bodied individuals. CONCLUSIONS: Ultrasonography is a reliable technology to evaluate AHD in MWUs in shoulder positions linked to wheelchair propulsion. Supraspinatus tendon thickness and occupation ratio of AHD adequately discriminate between MWUs with SCI and able-bodied individuals. This shows that these ultrasonographic measures can be used in future studies of populations with SCI to better understand the changes at the shoulder joint in MWUs.

Clinicians' and Researchers' Perspectives on Manual Wheelchair Data Loggers.

Recent studies have used data loggers to record a wide range of, sometimes differing, objective outcomes associated with the use of manual wheelchairs. To identify which outcomes are broadly perceived to be the most important to measure when objectively documenting manual wheelchair use, a cross-sectional survey was conducted with groups of researchers and clinicians in the field of wheeled mobility. We also surveyed the challenges these groups experienced when using data loggers. The survey was informed by a previous scoping review of the scientific and gray literature. Seventy-four people with various academic and professional backgrounds completed the survey: 57 researchers (77.0%) and 17 clinicians (23.0%). Regarding the importance they attributed to commonly measured outcomes, the most highly rated outcome identified by both groups was "distance traveled." There were significant differences between the groups' perspectives in rating and ranking the importance of "pressure-relief activities," "seat pressure," and "acceleration." In terms of challenges or barriers associated with the use of data loggers for monitoring manual wheelchair use, it appears that researchers and clinicians have relatively similar needs and preferences. However, only clinicians reported that the time they wanted to, or could, allocate to review recorded information was a potential hardship. Our hope is that these results will help further development and increase the functionality and applicability of data loggers for manual wheelchairs in research and clinical contexts.

Pilot Study of a Peer-Led Wheelchair Training Program to Improve Self-Efficacy Using a Manual Wheelchair: A Randomized Controlled Trial.

OBJECTIVES: To evaluate the effect of a peer-led wheelchair training program on self-efficacy of manual wheelchair (MWC) use and to explore influences of the intervention on MWC skills, life-space mobility, and satisfaction with participation. DESIGN: Pilot randomized controlled trial. SETTING: Rehabilitation center and community. PARTICIPANTS: Community-living MWC users (N=28; mean MWC experience, 13y; mean age, 49y; 6 [21%] women). INTERVENTIONS: The experimental group (n=16) received six 1.5-hour sessions of a peer-led self-efficacy-enhanced wheelchair training program (WheelSee). On the basis of individualized goals, peer trainers administered WheelSee to pairs of MWC users. The control group (n=12) received no intervention. MAIN OUTCOME MEASURES: The primary outcome--wheelchair use self-efficacy--was assessed using the Wheelchair Use Confidence Scale (WheelCon) version 3.0. Secondary outcomes included wheelchair skills capacity and performance (Wheelchair Skills Test Questionnaire version 4.1), life-space mobility (Life Space Assessment), and satisfaction with participation (Wheelchair Outcome Measure). RESULTS: Controlling for baseline scores, an analysis of covariance revealed that WheelSee had a large statistically significant effect on MWC use self-efficacy in community-living adult MWC users (Cohen d=1.4; P=.002) than in a control group. WheelSee also had a large statistically significant effect on MWC skills capacity (Cohen d=1.3; P=.003) and performance (Cohen d=1.0; P=.02). There were no statistically significant differences in life-space mobility or satisfaction with participation scores between the groups. CONCLUSIONS: A peer-led MWC training program improves wheelchair use self-efficacy in adult MWC users and had a positive influence on other wheelchair-related outcomes. WheelSee may offer a promising intervention strategy to accommodate the training needs of community-living MWC users.

Systematic Review and Meta-Analysis of Peer-Led Self-Management Programs for Increasing Physical Activity.

PURPOSE: Approximately 85 % of Canadians are not physically active enough to achieve health benefits. Peer-led self-management programs are becoming an increasingly popular strategy for modifying health behaviors, including physical activity. The purpose of this study was to systematically review and meta-analyze the effect of peer-led self-management interventions on physical activity. METHODS: PubMed, MEDLINE, PsycINFO, EMBASE, CINAHL, and Cochrane Database of Systematic Reviews databases were systematically searched to identify all relevant randomized controlled trials that evaluated the effect of peer-led self-management on physical activity. The studies were described and effect size data were included in meta-analyses. Subgroup analyses were performed according to type of physical activity outcome (i.e., duration, frequency, other). RESULTS: Twenty-one studies were included in the review and 14 reported statistically significant improvements in physical activity. A meta-analysis of 17 studies showed a statistically significant moderate pooled effect (standardized mean difference (SMD) = 0.4, p < 0.001) of peer-led self-management programs on physical activity immediately post-intervention. The intervention had a large statistically significant effect based on the four studies that included follow-up measures (SMD = 1.5, p = 0.03). Meta-analysis of nine studies that used similar outcomes (i.e., minutes of physical activity) revealed a statistically significant small effect (SMD = 0.2, p < 0.001). CONCLUSION: Peer-led self-management programs appear to be effective at increasing weekly duration of physical activity in various populations, but the effect size is small. Training peers to encourage increased physical activity may provide an effective method for reaching various clinical and non-clinical populations. More research is needed using validated and consistent physical activity outcomes.

To What Extent Can the Use of a Mobility Assistance Dog Reduce Upper Limb Efforts When Manual Wheelchair Users Ascend a Ramp?

Biomechanical evidence is needed to determine to what extent the use of a mobility assistance dog (AD(Mob)) may minimize mechanical loads and muscular demands at the upper limbs among manual wheelchair users. This study quantified and compared upper limb efforts when propelling up a ramp with and without an AD(Mob) among manual wheelchair users. Ten manual wheelchair users with a spinal cord injury who own an AD(Mob) ascended a ramp with and without their AD(Mob). The movements of the wheelchair and upper limbs were captured and the forces applied at the pushrims were recorded to compute shoulder mechanical loading. Muscular demand of the pectoralis major, anterior deltoid, biceps, and the triceps was normalized against the maximum electromyographic values. The traction provided by the AD(Mob) significantly reduced the total force applied at the pushrim and its tangential component while the mechanical effectiveness remained similar. The traction provided by the AD(Mob) also resulted in a significant reduction in shoulder flexion, internal rotation, and adduction moments. The muscular demands of the anterior deltoid, pectoralis major, biceps, and triceps were significantly reduced by the traction provided by the AD(Mob). The use of AD(Mob) represents a promising mobility assistive technology alternative to minimize upper limb mechanical loads and muscular demands and optimize performance during wheelchair ramp ascent.

Exploratory Validation of a Multidimensional Power Wheelchair Outcomes Toolkit.

OBJECTIVE: To evaluate the relation among the measures in a power wheelchair outcomes toolkit. DESIGN: We performed path analysis of cross-sectional data from self-report questionnaires and 1 objective measure. SETTING: Six sites. PARTICIPANTS: A convenience sample of power wheelchair users (N=128). Most (n=69; 53.9%) participants were women. Multiple sclerosis and spinal cord injury/disease were the most common diagnoses. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The power wheelchair version of the Wheelchair Skills Test version 4.1 was used to carry out an objective evaluation of capacity to perform 32 wheelchair skills. The Late-Life Disability Index measured frequency of participation in 16 life activities. The Life-Space Assessment measured independence, extent, and frequency of mobility. The Assistive Technology Outcomes Profile for Mobility was used to assess perceived difficulty performing activity and participation using assistive technology. The Wheelchair Use Confidence Scale for powered wheelchair users captured users' self-efficacy with wheelchair use. RESULTS: Wheelchair confidence was independently associated with less difficulty with activity (ß=.028, P=.002) and participation (ß=.225, P<.001), increased life space (ß=.095, P<.003), and greater wheelchair skills (ß=.30, P<.001). Less perceived difficulty with activity was independently associated with increased frequency of participation (ß=.55, P<.001). Life-space mobility was independently associated with increased frequency of participation (ß=.167, P<.001). Less difficulty with participation was independently associated with greater life-space mobility (ß=.59, P<.001) and greater frequency of participation (ß=.13, P<.001). CONCLUSIONS: This study provides empirical support for the measures included as part of the power wheelchair outcomes toolkit. They appear to provide complementary information on a variety of constructs related to power wheelchair use.

Effectiveness of a Wheelchair Skills Training Program for Powered Wheelchair Users: A Randomized Controlled Trial.

OBJECTIVES: To test the hypothesis that powered wheelchair users who receive the Wheelchair Skills Training Program (WSTP) improve their wheelchair skills in comparison with a control group that receives standard care, and secondarily to assess goal achievement, satisfaction with training, retention, injury rate, confidence with wheelchair use, and participation. DESIGN: Randomized controlled trial. SETTING: Rehabilitation centers and communities. PARTICIPANTS: Powered wheelchair users (N=116). INTERVENTION: Five 30-minute WSTP training sessions. MAIN OUTCOME MEASURES: Assessments were done at baseline (t1), posttraining (t2), and 3 months posttraining (t3) using the Wheelchair Skills Test Questionnaire (WST-Q version 4.1), Goal Attainment Score (GAS), Satisfaction Questionnaire, injury rate, Wheelchair Use Confidence Scale for Power Wheelchair Users (WheelCon), and Life Space Assessment (LSA). RESULTS: There was no significant t2-t1 difference between the groups for WST-Q capacity scores (P=.600), but the difference for WST-Q performance scores was significant (P=.016) with a relative (t2/t1 × 100%) improvement of the median score for the intervention group of 10.8%. The mean GAS ± SD for the intervention group after training was 92.8%±11.4%, and satisfaction with training was high. The WST-Q gain was not retained at t3. There was no clinically significant difference between the groups in injury rate and no statistically significant differences in WheelCon or LSA scores at t3. CONCLUSIONS: Powered wheelchair users who receive formal wheelchair skills training demonstrate modest, transient posttraining improvements in their WST-Q performance scores, have substantial improvements on individualized goals, and are positive about training.
