Community Participation Transition After Stroke (COMPASS) Randomized Controlled Trial: Effect on Adverse Health Events.

OBJECTIVE: To compare adverse health events in intervention versus control group participants in the Community Participation Transition After Stroke trial to reduce barriers to independent living for community-dwelling stroke survivors. DESIGN: Randomized controlled trial. SETTING: Inpatient rehabilitation (IR) to home and community transition. PARTICIPANTS: Stroke survivors aged ≥50 years being discharged from IR who had been independent in activities of daily living prestroke (N=183). INTERVENTIONS: Participants randomized to intervention group (n=85) received home modifications and self-management training from an occupational therapist over 4 visits in the home. Participants randomized to control group (n=98) received the same number of visits consisting of stroke education. MAIN OUTCOME MEASURES: Death, skilled nursing facility (SNF) admission, 30-day rehospitalization, and fall rates after discharge from IR. RESULTS: Time-to-event analysis revealed that the intervention reduced SNF admission (cumulative survival, 87.8%; 95% confidence interval [CI], 78.6%-96.6%) and death (cumulative survival, 100%) compared with the control group (SNF cumulative survival, 78.9%; 95% CI, 70.4%-87.4%; P=.039; death cumulative survival, 87.3%; 95% CI, 79.9%-94.7%; P=.001). Thirty-day rehospitalization also appeared to be lower among intervention participants (cumulative survival, 95.1%; 95% CI, 90.5%-99.8%) than among control participants (cumulative survival, 86.3%; 95% CI, 79.4%-93.2%; P=.050) but was not statistically significant. Fall rates did not significantly differ between the intervention group (5.6 falls per 1000 participant-days; 95% CI, 4.7-6.5) and the control group (7.2 falls per 1000 participant-days; 95% CI, 6.2-8.3; incidence rate ratio, 0.78; 95% CI, 0.46-1.33; P=.361). CONCLUSIONS: A home-based occupational therapist-led intervention that helps stroke survivors transition to home by reducing barriers in the home and improving self-management could decrease the risk of mortality and SNF admission after discharge from rehabilitation.

The Relationship of Exercise, Psychosocial Factors, and Social Participation Among Adults Aging With Long-Term Physical Disability: A Cross-Sectional Study.

PURPOSE: This study investigated the relationships among exercise engagement, psychosocial factors, and social participation for adults aging with physical disabilities (AAwPD). DESIGN: A cross-sectional study within a community-based cohort study of participation among AAwPD was conducted. SETTING: A comprehensive survey was administered online or via telephone. PARTICIPANTS: Participants were 474 individuals between the ages of 45-65, primarily living in the Midwestern United States, who reported living with a physical disability for at least 5 years. METHOD: Survey questions created based on prior consolidation of activity domains assessed exercise engagement. Psychosocial health and social participation were measured using the Patient Reported Outcomes Measurement Information System. Chi-square tests, t-tests, and a general linear model were used to examine differences between exercisers and non-exercisers. RESULTS: Participants who exercised reported less pain (P < .001), fatigue (P < .001), and depression (P < .001) and greater self-efficacy for management of chronic conditions (P = .002), satisfaction with participation in social roles and activities (P < .001), and ability to participate in social roles and activities (P < .001) compared with non-exercising participants. CONCLUSIONS: AAwPD who exercised reported fewer secondary conditions and greater social participation. Although causal relationships cannot be drawn, and the frequency, duration, and intensity of exercise were not examined, this study lays important groundwork for future research to determine the health and participation benefits of exercise for AAwPD. Future studies should also focus on the development of exercise interventions to support successful aging with disability.

Consistency of participation over time among persons aging with physical disability as measured by a tool designed for use among community-based organizations.

BACKGROUND: Community participation measures for persons aging with disability were developed and evaluated to support community-based organizations (CBOs) with efficient assessment of change in participation and need for supports/services to facilitate participation. OBJECTIVE: To evaluate a set of nine activity domain measures to broadly assess community participation and change in participation over time. METHODS: A community-based sample (N = 323) of persons ages 45-65 responded to a survey with repeated measures three times annually (T1, T2, T3) between 2019 and 2022. Nine activity domain measures were developed based on extant research and evaluated with assistance from community-based support service providers. Statistical analyses employed T-tests and chi-square tests to assess change in participation over time, perceptions of participation satisfaction, and assistance needed to facilitate participation. Participants were asked if they thought changes were attributable to aging, the COVID-19 pandemic, or other factors. RESULTS: Findings showed varying levels of participation across the nine activity domains, with the lowest participation rate for employment and the highest participation rates for personal leisure and managing medications across T1, T2, and T3. Change in participation over the three-year period was limited; most change was reported as activity reduction. In general, respondents indicated that reduction was due to their aging or the COVID-19 pandemic. Personal assistance, transportation, environmental modifications, and improved health were identified as factors needed to help increase participation levels. CONCLUSION: The activity domain measures demonstrated efficiency in identifying participation rates and change. CBOs may deem them useful for assessing support and service needs to facilitate participation.

Text messaging intervention for fatigue self-management in people with stroke, spinal cord injury, and multiple sclerosis: A pilot study.

BACKGROUND: Fatigue negatively impacts the function and quality of life of people with disabilities (PwD). Mobile health (mHealth) platforms are recognized as effective and accessible approaches to delivering health interventions and may show higher satisfaction by tailoring the information toward personalized needs for PwD. OBJECTIVE: To evaluate the acceptability, feasibility, and participant engagement with a Short Message Service (SMS) text messaging intervention for fatigue self-management and to explore the pre- and post-score health changes in PwD. METHODS: A total of 27 PwD (multiple sclerosis = 9, spinal cord injury = 9, or stroke = 9) experiencing fatigue in their daily lives participated in a 12-week self-management text messaging intervention. Participants completed a demographic survey and health outcome measures, including patient activation, self-efficacy for managing symptoms, fatigue, sleep, and satisfaction with participation in social roles before and after the intervention. Participants also completed a client satisfaction questionnaire after the intervention. We also tracked the program retention and SMS response rates over the 12-week intervention period. RESULTS: Twenty-five participants completed the entire intervention (93% retention rate), and the overall SMS response rate was 84.67%, indicating high acceptability and adherence to the intervention. The mean satisfaction score was 3.18, indicating high satisfaction with the intervention. Despite finding a negligible effect on patient activation, we found a small intervention effect on self-efficacy for managing symptoms (η2 = 0.04) and moderate effects on fatigue (η2 = 0.06-0.12), sleep (η2 = 0.11), and satisfaction with participation in social roles (η2 = 0.08). CONCLUSIONS: This study provides initial feasibility and health outcome change evidence to support an SMS text messaging intervention to manage fatigue in PwD.

Influence of falls, fall-related injuries, and fear of falling on social participation in people aging with long-term physical disability: a cross-sectional study.

PURPOSE: This study examined prevalence and relationships among falls, injuries, fear of falling, and social participation in people aging with long-term physical disability (PAwLTPD). MATERIALS AND METHODS: A convenience sample of 474 PAwLTPD recruited from community agencies and social media as baseline of a longitudinal cohort study. Inclusion criteria: 45-65 years, self-reported physical disability for ≥5 years, and English-speaking. Self-report surveys of physical/mental health, falls in the past year, fear of falling, and Patient-Reported Outcomes Measurement Information System (PROMIS) ability and satisfaction with participation in social roles and activities measures were collected. RESULTS: Mean age 56.8 years; participants were mostly female (66.7%) and White (61.4%). Nearly 65% reported a fall; 56.6% of falls resulted in injury. Falls and fall-related injuries were associated with worse physical/mental health and presence of >5 health conditions. Seventy-five percent of participants reported fear of falling. Lower ability and satisfaction with participation were found in participants who fell and worried about falls. CONCLUSIONS: PAwLTPD are at increased risk of falls, fall-related injuries, and fear of falling, which affects their ability to engage in social activities. Future research is needed to understand circumstances associated with falls and to develop effective interventions to address falls in PAwLTPD.

Community-dwelling individuals aged 45­65 years who are aging with long-term physical disabilities report increased rates of falls, fall-related injuries, and fear of falling.People aging with long-term physical disabilities who experience falls report decreases in their social participation.Additional work within the rehabilitation field is needed to develop effective, evidence-based interventions to reduce the occurrence of falls among individuals aging with long-term physical disability.

Social participation of adults aging with long-term physical disabilities: A cross-sectional study investigating the role of transportation mode and urban vs rural living.

BACKGROUND: Adults aging with long-term physical disabilities (AAwPDs) experience barriers in the built environment that can hinder their participation in meaningful social roles and activities. However, interventions addressing built environment barriers to participation for AAwPD are limited. OBJECTIVE: The purpose of this study was to examine how the built environment and other socioenvironmental factors influence the social participation of AAwPD to inform future interventions and service provision. We hypothesized that social participation would be significantly different between AAwPD using private versus public transportation and living in urban versus rural areas. METHODS: This cross-sectional study of 331 Missouri-dwelling AAwPD reports findings on relationships among transportation mode, urban versus rural residence, and ability to participate in social roles and activities using PROMIS measures. A multivariate analysis of covariance (MANCOVA) explored differences in social participation across transportation mode and residential location. Linear regression examined associations among socioenvironmental factors, individual factors, and social participation. RESULTS: The MANCOVA demonstrated significant differences in social participation across transportation mode and urban versus rural residential location. Specifically, AAwPD using paratransit and living in urban areas reported significantly higher social participation than rural-dwelling individuals and private transportation users (p < .001). The linear regression revealed that individual factors served a larger role in predicting social participation than built or social environmental factors. CONCLUSIONS: Our findings suggest that transportation mode plays a significant role in shaping social participation outcomes for AAwPD. However, compared to built and social environmental factors, individual factors (i.e., physical function, 'aging-with-disability' symptoms) may restrict social participation more.

Mobility Disability and Exercise: Health Outcomes of an Accessible Community-Based Center.

Objective: The purpose of this study was to determine how support and guidance provided by trained professionals during a 12-week, community-based transition exercise program, impact health outcomes and continued engagement in physical activity for persons with a mobility disability (PwMD). Design: A single arm pre-post design was used. Setting: Accessible community-based health and wellness center. Participants: The study included 244 PwMD using a mobility device. Interventions: Participants completed a 12-week transition exercise program provided through an accessible community facility that provided education and support to complete endurance and strength related exercises as well as programming to encourage transition to self-directed engagement in exercise. Main Outcome Measures: Bodyweight, BMI, pain, perceived exertion, speed, and distance during cardiovascular fitness testing, and strength were measured pre and post exercise program. The number of participants that signed up for a monthly membership after the program was also monitored. Results: For the total group, average pain reported over previous 30 days decreased significantly (p < 0.01), current daily pain decreased significantly (p < 0.05), perceived exertion at the end of the 9-min endurance test decreased significantly (p < 0.05), and the four upper extremity strength exercises showed large, significant strength gains (p < 0.01) after the program. There was no significant change in bodyweight, BMI, or speed and distance completed during endurance testing. At the completion of the program, 76% of participants enrolled in a monthly membership at the facility with the intentions to continue to exercise regularly. Conclusions: This study provides evidence that an accessible community-based exercise program, with a transitional component supported by trained professionals, can support the exercise goals of PwMD and improve strength, decrease pain, and may promote regular exercise adoption for PwMD.

An observational study of personal and environmental factors associated with attendance at a community-based adaptive fitness center for adults with physical disabilities.

BACKGROUND: Regular exercise has many benefits for adults with physical disabilities (AwPD). Despite these benefits, significant barriers to participating in exercise exist for AwPD. Community-based adaptive fitness centers promote exercise for AwPD by minimizing barriers. Research has yet to clearly examine the personal and environmental factors associated with enrollment and attendance rates of AwPD in community-based adaptive fitness centers. OBJECTIVE: The purpose of our study was to explore personal and environmental factors associated with AwPD and their attendance at a community-based adaptive fitness center once enrolled. METHODS: Individuals aged 18-85 with a physical disability interested in exercising were referred to a community-based adaptive fitness center. At initial assessment, participants completed demographics, health, barriers to exercise, and exercise self-efficacy (ESE) surveys. Following initial assessment, participant visits to the fitness center were tracked for six months. RESULTS: Of 106 participants, 27 never visited the facility after initial assessment, and the remaining participants with six months of attendance data (n = 67) averaged 14.9 (SD = 14.2) visits. Correlation results showed a negative curvilinear relationship between number of visits and years living with disability (rs = -0.24, p < 0.05), with higher attendance associated with more recent diagnosis. Logistic and stepwise regressions showed that ESE score (ß = 0.107, p = 0.026) was the only significant predictor of attending the fitness center once enrolled. CONCLUSIONS: This study demonstrates the importance of understanding personal and environmental factors and assessing ESE for AwPD who are newly enrolled in a community-based adaptive fitness center.

Impact of the COVID-19 Pandemic on Psychosocial Health of Persons With Spinal Cord Injury: Investigation of Experiences and Needed Resources.

Background: Emerging evidence suggests that the COVID-19 pandemic has been accompanied by increased rates of depression and social isolation. However, we do not yet understand how the COVID-19 pandemic has affected the psychosocial health of people with spinal cord injury (PwSCI), a population that is already at risk of experiencing mental health conditions. Objectives: The aims of the study were to (1) examine the impact of the pandemic on the psychosocial health of PwSCI and (2) investigate the experiences of PwSCI and resources they reported needing during the peak of the pandemic. Methods: A cross-sectional survey with closed- and open-ended questions was administered to 51 PwSCI. Participants were included if they had an SCI, were 18 years or older, lived in St. Louis, Missouri, and surrounding areas, and understood English. Results: Canonical correlation showed a significant association between financial security, food insecurity, and personal assistance service use and adverse psychosocial health outcomes (p < .001). Participants reported interest in resources related to COVID-19 precautions for wheelchair users as well as home exercise programming and financial assistance with utilities. Finally, qualitative analysis revealed four major themes: (1) mental health during the pandemic, (2) financial concerns and reduced access to personal assistance services, (3) feelings of social isolation prior to the pandemic, and (4) local and national authorities' handling of the pandemic. Conclusion: PwSCI are impacted by the COVID-19 pandemic and reported a variety of resource needs. These findings may inform service providers, support systems, and organizations to better support PwSCI during times of crisis.

Examination of Community Participation of Adults With Disabilities: Comparing Age and Disability Onset.

Objective: Explore community participation between adults with disabilities ⩽50 and >50 years and between early-(⩽40) and late-(>40) onset disability. Method: A survey examining participation was conducted with a national convenience sample of 692 community-dwelling adults with disabilities. Results: Participants ⩽50 reported presence of more (p < .05) environmental supports for work/volunteer/education and use of transportation. Participants >50 had higher (p < .01) visits to pharmacies; higher (p < .05) evaluative quality of participation (EQOP) at gas stations, exercise facilities, beauty salons/barbers, and use of transportation (p < .01); and more difficulty participating without assistance at grocery stores (p < .05) and gas stations (p < .01). The early-onset group reported higher (p < .05) EQOP at work/volunteer/education and homes of family/friends. The late-onset group reported higher (p < .01) EQOP at exercise facilities; more (p < .05) environmental supports at pharmacies, restaurants, grocery stores (p < .01), doctors' offices (p ⩽ .01), and beauty salons/barbers (p < .01); greater (p < .01) influence of pain/fatigue; and more difficulty without assistance at grocery stores (p < .05) and gas stations (p < .01). Discussion: Understanding these differences can improve interventions to support community participation of individuals aging with disabilities.

Feasibility Trial of Tailored Home Modifications: Process Outcomes.

OBJECTIVE: The aim of this study was to conduct a process evaluation to examine the implementation of a randomized controlled trial of home modifications designed to reduce the risk of falls and improve daily activity performance among community-dwelling older adults. METHOD: A process evaluation was conducted alongside a blinded, randomized sham-controlled trial (n = 92). Participants were followed for 1 yr after intervention. The process evaluation was framed using the Reach, Effectiveness, Adoption, Implementation, and Maintenance framework. RESULTS: The treatment group improved daily activity performance over 12 mo compared with the sham control group (F = 4.13; p = .024). The intervention elements and dose were delivered with greater than 90% accuracy. Participants reported a 91% adherence rate at 12 mo. CONCLUSION: The complex intervention of home modifications examined in this study is acceptable to older adults, is feasible, and can be delivered with high fidelity for frail, community-dwelling older adults.

Environmental factors item development for persons with stroke, traumatic brain injury, and spinal cord injury.

OBJECTIVES: To describe methods used in operationalizing environmental factors; to describe the results of a research project to develop measures of environmental factors that affect participation; and to define an initial item set of facilitators and barriers to participation after stroke, traumatic brain injury, and spinal cord injury. DESIGN: Instrument development included an extensive literature review, item classification and selection, item writing, and cognitive testing following the approach of the Patient-Reported Outcomes Measurement Information System. SETTING: Community. PARTICIPANTS: Content area and outcome measurement experts (n=10) contributed to instrument development; individuals (n=200) with the target conditions participated in focus groups and in cognitive testing (n=15). INTERVENTIONS: None. MAIN OUTCOME MEASURES: Environmental factor items were categorized in 6 domains: assistive technology; built and natural environment; social environment; services, systems, and policies; access to information and technology; and economic quality of life. RESULTS: We binned 2273 items across the 6 domains, winnowed this pool to 291 items for cognitive testing, and recommended 274 items for pilot data collection. CONCLUSIONS: Five of the 6 domains correspond closely to the International Classification of Functioning, Disability and Health taxonomy of environmental factors; the sixth domain, economic quality of life, reflects an important construct that reflects financial resources that affect participation. Testing with a new and larger sample is underway to evaluate reliability, validity, and sensitivity.

Person factors and work environments of workers who use mobility devices.

BACKGROUND: Nearly 25% of people with mobility impairments and limitations who are of working age are employed, yet few studies have examined their perspectives on their jobs or work environments required to complete job tasks. OBJECTIVE: The purpose of this study was to describe the factors that contribute to successful employment for those who use mobility devices. PARTICIPANTS: A convenience sample of 132 workers who use power wheelchairs, manual wheelchairs, canes, crutches or walkers. METHOD: Participants completed an online version of the Mobility Device User Work Survey (MWS). A multivariate analysis and a two-step multiple linear regression analysis were used. RESULTS: Study participants had few secondary health conditions that influenced their work. Employee satisfactoriness to their employers was high. Accessibility of worksites was high. Assistive technologies were inexpensive, and personal assistance was used infrequently and usually was unpaid. Co-worker communications were very positive. Flexible work rules and supportive managers were highly valued. Job satisfaction positively correlated with accessibility, work tasks, co-worker communication and work support. CONCLUSION: The description of work environments of successfully employed mobility device users can provide some useful guidance to employers, vocational rehabilitation (VR) counselors and unemployed mobility device users to balance employee abilities and preferences with the needs of employers.

Work environments of people with mobility impairments and limitations: Mobility Device User Work Survey (MWS).

BACKGROUND: Few studies of employed people who use wheelchairs, canes, crutches or walkers have been reported in the literature. One reason for this paucity of research reports is that surveys are most often made of unemployed individuals with disabilities a defined broadly. Understanding the work site of successfully employed people who use mobility devices requires the development of as survey that can be used to examine the important features of worksite from employees who use mobility devices at their worksites. OBJECTIVE: This article describes the development and psychometrics of a survey on currently employed people with lower limb impairments and mobility limitations who use mobility devices. The items in the Mobility Device User Work Survey (MWS) were based on interviews and survey items pilot tested on employed mobility device users. PARTICIPANTS: A sample of 183 employed people who use mobility devices including wheelchairs, canes, crutches or walkers was recruited using internet postings on disability-related organizations. The average age of the sample was 46.3, most were college educated, 72% used wheelchairs and the average number of years of employment was 24. METHODS: The MWS was completed by 183 people who met the inclusion criteria. The survey was sent to these same people a second time and 132 of them returned the second survey. RESULTS: The MWS consists of 106 questions on demographic, work and worksite characteristics and 58 subjective evaluation items that were organized into five scales. The internal consistencies (Cronbach's alpha) of the five scales were moderate (0.72) to good (0.93). Stability values of the five scales were calculated using correlations between forms and ranged from 0.70 to 0.80. The evaluative scales were analyzed using exploratory factor analysis. CONCLUSIONS: The MWS provides a tool for studying the variables that influence employed people who use mobility devices. Future studies of unemployed people who use mobility devices may benefit from using the results of the MWS to plan interventions.

Home lighting assessment for clients with low vision.

OBJECTIVE: The goal was to develop an objective, comprehensive, near-task home lighting assessment for older adults with low vision. METHOD: A home lighting assessment was developed and tested with older adults with low vision. Interrater and test-retest reliability studies were conducted. Clinical utility was assessed by occupational therapists with expertise in low vision rehabilitation. RESULTS: Interrater reliability was high (intraclass correlation coefficient [ICC] = .83-1.0). Test-retest reliability was moderate (ICC = .67). Responses to a Clinical Utility Feedback Form developed for this study indicated that the Home Environment Lighting Assessment (HELA) has strong clinical utility. CONCLUSION: The HELA provides a structured tool to describe the quantitative and qualitative aspects of home lighting environments where near tasks are performed and can be used to plan lighting interventions. The HELA has the potential to affect assessment and intervention practices of rehabilitation professionals in the area of low vision and improve near-task performance of people with low vision.

Preclinical Alzheimer disease and risk of falls.

OBJECTIVE: We determined the rate of falls among cognitively normal, community-dwelling older adults, some of whom had presumptive preclinical Alzheimer disease (AD) as detected by in vivo imaging of fibrillar amyloid plaques using Pittsburgh compound B (PiB) and PET and/or by assays of CSF to identify Aß42, tau, and phosphorylated tau. METHODS: We conducted a 12-month prospective cohort study to examine the cumulative incidence of falls. Participants were evaluated clinically and underwent PiB PET imaging and lumbar puncture. Falls were reported monthly using an individualized calendar journal returned by mail. A Cox proportional hazards model was used to test whether time to first fall was associated with each biomarker and the ratio of CSF tau/Aß42 and CSF phosphorylated tau/Aß42, after adjustment for common fall risk factors. RESULTS: The sample (n = 125) was predominately female (62.4%) and white (96%) with a mean age of 74.4 years. When controlled for ability to perform activities of daily living, higher levels of PiB retention (hazard ratio = 2.95 [95% confidence interval 1.01-6.45], p = 0.05) and of CSF biomarker ratios (p < 0.001) were associated with a faster time to first fall. CONCLUSIONS: Presumptive preclinical AD is a risk factor for falls in older adults. This study suggests that subtle noncognitive changes that predispose older adults to falls are associated with AD and may precede detectable cognitive changes.

Development of a community mobility skills course for people who use mobility devices.

OBJECTIVE: We assessed mobility device skills in a lived-in environment on a community mobility skills course (CMSC) and related those skills to previously demonstrated skills in a controlled environment on an inside mobility skills course (IMSC). METHOD: Six mobility device users were selected from 91 adults who had previously completed the IMSC. Each of the following device groups was represented: power wheelchair, manual wheelchair, scooter, cane, crutch, and walker. CMSC tasks were modified from IMSC tasks and designed using materials in the community. RESULTS: All participants completed at least half of the CMSC tasks faster than they completed the corresponding IMSC tasks. The number of tasks on which participants improved and the amount of improvement varied by difficulty of task and mobility device used. CONCLUSION: Some mobility device skills used in controlled environments appear to transfer to community settings; others do not. Skills required for community participation may partially depend on mobility device used.

Cognitive, visual, auditory, and emotional factors that affect participation in older adults.

OBJECTIVE: To determine whether changes in hearing, cognition, depression, and vision affect daily life participation and whether screening tests that identify problems could be used in the home. METHOD: Interviewers assessed presence of medical conditions, social class, distance acuity, cognition, hearing, depression, and participation using valid screening tools. Participation scores were subgrouped according to negative or positive results. Multiple regression analysis determined association of screening tests with participation. RESULTS: Eighty-eight older adults, ages 62-90, participated. Positive screening tests were found in 43% of participants for distance acuity, 9% for cognitive problems, 8% for depression, and 15% for hearing loss. Relationships were found among age, cognition, depression, and vision and participation. CONCLUSION: Mild levels of decreased vision, depression, and decreased cognition are associated with lower participation. These conditions can be screened by occupational therapists and managed to help older adults remain active and maintain their health.

Structural equation modeling of the relationships between participation in leisure activities and community environments by people with mobility impairments.

OBJECTIVE: To examine the linkages between the constructs of participation and the environment for a set of leisure activities (attending concerts, attending movies, attending sporting events). DESIGN: Self-report surveys of the influence of the environment on participation were analyzed using structural equation modeling. Temporal, evaluative, and health-related aspects of leisure activities were selected as latent variables associated with participation. The environmental construct consisted of the latent variables of the influence on participation of the natural, interpersonal, built, background, and supportive environments. SETTING: Midwestern United States. PARTICIPANTS: A purposive sample of people (N=604) with mobility limitations. INTERVENTION: None. MAIN OUTCOME MEASURES: Measures of relationships between participation in leisure activities and the environment of people with mobility limitations. RESULTS: Structural equation modeling can be an important tool for empirically examining the contributions of the component latent variables of participation and the environment. CONCLUSIONS: A model that fits participation by people with disabling conditions in their environment can provide guidance for community-based interventions and person-based therapies.

The influence of verbal training and visual feedback on manual wheelchair propulsion.

PURPOSE: To determine if verbal training with visual feedback improved manual wheelchair propulsion; to examine propulsion differences between an individual with paraplegia and an individual with tetraplegia. METHOD: Quasi-experimental study: Nine manual wheelchair-using adults participated in propulsion assessments and training. Baseline propulsion performance was measured on several tasks on different surfaces. Participants were trained on a wheelchair treadmill with verbal and visual feedback to increase push length, reduce push frequency and to modify propulsion pattern. Handrim biomechanics were measured with an instrumented wheel. Changes in propulsion were assessed. Differences in propulsion characteristics between a participant with paraplegia and a participant with tetraplegia were examined. RESULTS: Push length increased (p < 0.05), push frequency decreased (p < 0.01) and peak (p < 0.05) and average (p < 0.01) forces increased immediately after training. These changes were not sustained over time. Graphic representations showed differences in propulsion characteristics between a participant with paraplegia and a participant with tetraplegia. CONCLUSIONS: Verbal training may produce changes in push biomechanics of manual wheelchair users. Longer training periods may be needed to sustain propulsion changes. Findings from this study support other studies that have shown propulsion differences between people with tetraplegia and paraplegia. Propulsion training for populations with upper-extremity impairments warrants further study.
