Manual wheelchair skills: objective testing versus subjective questionnaire

A Remote-Learning Course can improve the subjective wheelchair-skills performance and confidence of wheelchair service providers: an observational cohort study

PURPOSE

To test the hypothesis that a Remote-Learning Course improves the subjective wheelchair-skills performance and confidence of wheelchair service providers, and to determine the participants' views on the Course.

METHODS

This was an observational cohort study, with pre-post comparisons. To meet the objectives of the six-week Course, the curriculum included self-study and weekly one-hour remote meetings. Participants submitted their Wheelchair Skills Test Questionnaire (WST-Q) (Version 5.3.1) "performance" and "confidence" scores before and after the Course. Participants also completed a Course Evaluation Form after the Course.

RESULTS

The 121 participants were almost all from the rehabilitation professions, with a median of 6 years of experience. The mean (SD) WST-Q performance scores rose from 53.4% (17.8) pre-Course to 69.2% (13.8) post-Course, a 29.6% relative improvement (p < 0.0001). The mean (SD) WST-Q confidence scores rose from 53.5% (17.9) to 69.5% (14.3), a 29.9% relative improvement (p < 0.0001). Correlations between performance and confidence were highly significant (p < 0.0001). The Course Evaluation indicated that most participants found the Course useful, relevant, understandable, enjoyable, "just right" in duration, and most stated that they would recommend the Course to others.

CONCLUSIONS

Although there is room for improvement, a Remote-Learning Course improves the subjective wheelchair-skills performance and confidence scores of wheelchair service providers by almost 30%, and participants were generally positive about the Course.

Association between individual wheelchair skills and fitness in community-dwelling manual wheelchair users with spinal cord injuries

PURPOSE

Wheelchair skills are a key component to promotion of community participation among persons with spinal cord injury (SCI). The objective of this secondary analysis was to examine the association between individual wheelchair skills from the Wheelchair Skills Test Questionnaire (WST-Q) and fitness among community-dwelling adults with SCI.

MATERIALS AND METHODS

Twenty-six adults were recruited to complete the WST-Q and a standard graded aerobic wheelchair exercise test on a motorized treadmill for assessing peak power output (POpeak).

RESULTS

Spearman Rho rank-order correlation (ρ) analyses indicated statistically significant correlations between POpeak and six basic (ρ = 0.41-0.57), eight intermediate (ρ = 0.44-0.59), and nine advanced (ρ = 0.42-0.80) WST-Q skill scores. After controlling for sex and injury level (Partial Spearman Rho rank order) significant correlations persisted for four advanced skills (i.e., descends high curb, turns in place in wheelie position, descends steep incline in wheelie position, descends high curb in wheelie position; ρ = 0.46-0.59) and one additional skill (i.e., ascends high curb ρ = 0.51).

CONCLUSIONS

More advanced wheelchair skills are significantly associated with fitness in persons with SCI. The directionality of the skills-fitness relationship, specifically whether wheelchair skills facilitate greater fitness or fitness is a prerequisite for certain wheelchair skills needs to be determined in future, larger studies. However, results from this study provide a comprehensive list of wheelchair skills that are associated with fitness that can be directly applied to guide further research and practice promoting community participation among persons with SCI.Implications for RehabilitationSignificant positive associations exist between advanced wheelchair skills (i.e., descends high curb, turns in place in wheelie position, descends steep incline in wheelie position, descends high curb in wheelie position and ascends high curb) and fitness in manual wheelchair users with spinal cord injury (SCI).This study provides a list of skills associated with fitness to guide clinical practice and areas for further rehabilitation research assessing the directionality of the relationship between fitness and wheelchair skills.

French-Canadian translation, cultural adaptation, and preliminary evaluation of the wheelchair service provision - basic test validity among occupational therapy students

PURPOSE

The objectives were: (1) to translate and adapt the International Society of Wheelchair Professional (ISWP) basic Wheelchair Service Provision Test (bWSPT) into French-Canadian and (2) to conduct a preliminary evaluation of the French-Canadian version of the ISWP bWSPT internal consistency and relations with other variables among French-Canadian occupational therapy students.

METHODS

For Phase 1, based on the International Test Commission Guidelines for Translating and Adapting Tests, a forward translation and adaptation from English to French-Canadian was conducted by a translation team. For Phase 2, the validity evidence of the French-Canadian bWSPT was evaluated through internal consistency and comparison of bWSPT scores and final grades of a wheelchair-specific course with a sample of occupational therapy students (positive, moderate correlation hypothesized). Internal consistency was measured with Cronbach's α. The correlation was calculated using the Spearman's Rank Correlation Coefficient.

RESULTS

For phase 1, 61 of 167 items of the forward adaptation were revised and modified. All revisions were a consensus by the translation team. For phase 2, we found a Cronbach's α of 0.50 and a correlation of ⍴ = 0.27 (p = 0.43) between the bWSPT French-Canadian version and the wheelchair-specific course final grade. The low variability of the data may explain the lower-than-expected correlation. Other possible data-driven reasons have been explored using post-hoc analysis.

CONCLUSION

The ISWP bWSPT, French-Canadian version, is not internally consistent and demonstrates a non-statistically significant, positive, weak correlation with the final grade of a wheelchair service provision-specific course among a cohort of 35 occupational therapy students.IMPLICATIONS FOR REHABILITATIONThe lack of adequately educated wheelchair service providers is a contributing factor to inappropriate wheelchair provision worldwide.The ISWP Wheelchair Service Provision Basic Test (ISWP bWSPT) has been created to evaluate competency among wheelchair service providers and provides a standardized test recognized internationally.A French-Canadian version of the ISWP bWSPT allows competency testing of French-speaking wheelchair service providers across Canada.This study shows that the French-Canadian version of the test is not internally consistent and has a low correlation with a wheelchair provision-specific course among a cohort of 35 occupational therapy students at a French-Canadian university suggesting further refinement is required to improve its measurement properties in this population of test-takers.

Exploring the Influence of a Community-Based Peer-Led Wheelchair Skills Training on Satisfaction with Participation in Children and Adolescents with Cerebral Palsy and Spina Bifida: A Pilot Study

BACKGROUND

Peer-led approaches improve satisfaction with participation, wheelchair skills and wheelchair use self-efficacy in adults, but the evidence is limited in children. This pilot study aimed to explore the influence of community-based, peer-led, group wheelchair training program (i.e., Seating To Go) on satisfaction with participation (primary outcome), wheelchair skills, and wheelchair use self-efficacy in children and adolescents with cerebral palsy and spina bifida.

METHODS

A single group pre-post design was used. Invitations were shared online and diffused by clinicians and advocacy and provider groups to recruit a convenience sample of eight pediatric wheelchair users. Participants completed the Seating To Go program in groups that were facilitated by adult wheelchair users. Satisfaction with participation (Wheelchair Outcome Measure-Young People), wheelchair skills (Wheelchair Skills Test), wheelchair use self-efficacy (Wheelchair Use Confidence Scale), and perceived wheelchair skills capacity (Wheelchair Skills Test Questionnaire; proxy rating: parents) were evaluated before and after the Seating To Go program. Descriptive statistics and nonparametric longitudinal data analysis were conducted to explore changes in all outcomes from baseline to post-intervention.

RESULTS

Pediatric wheelchair users (ranging in age from 5 to 15 years) and their parents reported statistically significant improvements in satisfaction with participation. The improvements in wheelchair skills and wheelchair confidence were also statistically significant, but not the parents' perception of their children's wheelchair skills.

CONCLUSIONS

A community-based peer-led approach to wheelchair skills training seems promising for improving wheelchair outcomes in pediatric wheelchair users. Further controlled studies with larger samples are warranted.

Impact of Falls and Fear of Falling on Participation, Autonomy and Life Satisfaction in the First Year After Spinal Cord Injury

Introduction

Individuals with spinal cord injury (SCI) experience reduced participation in meaningful activities, leading to reduced social engagement and negative psychological impact. Two factors that may affect participation post-SCI are fall status (e.g., having experienced a fall) and having a fear of falling. Our objective was to examine if and how fall status and fear of falling impact participation, autonomy and life satisfaction in the first year post-injury.

Methods

Adult inpatients of a SCI rehabilitation hospital were recruited. Following discharge, falls were tracked for 6 months and participants who fell at least once were categorized as “fallers”. At the end of the 6-month period, the Impact on Participation and Autonomy Questionnaire and Life Satisfaction Questionnaire 9 were administered, and participants were asked if they had a fear of falling (i.e., an ongoing concern about falling leading to the avoidance of activities they are capable of doing). Falls were reported using descriptive statistics. Ordinary least squares regression was used to evaluate the relationships between the independent variables (i.e., fall status and fear of falling) and each dependent variable (i.e., questionnaire scores).

Results

Seventy-one individuals were enrolled in the study; however, 11 participants were lost to follow-up. The included participants (n = 60) were 58.4 ± 14.6 years old and 99 ± 60.3 days post-injury. Over one third (38.3%) of participants fell over the 6-month tracking period. Twenty-seven participants (45%) reported a fear of falling and 14 (51.9%) of these participants were fallers. Fear of falling significantly predicted scores of autonomy indoors (β = 3.38, p = 0.04), autonomy outdoors (β = 2.62, p = 0.04) and family role (β = 3.52, p = 0.05).

Conclusion

Individuals with subacute SCI and a fear of falling experienced reduced participation and autonomy, but with no differences in life satisfaction compared to those without a fear of falling. In contrast, having experienced a fall did not impact participation, autonomy or life satisfaction. In the first year after SCI, rehabilitation programs should place specific attention on the presence of fear of falling to help individuals with SCI prepare for everyday mobility challenges.

Cross-cultural adaptation and reliability of the Brazilian version of the wheelchair skills test-questionnaire 4.3 for manual wheelchair users

The Wheelchair Skills Test-Questionnaire form for Manual Wheelchairs Operated by Wheelchair Users (WSTQ-M-WCU 4.3) assesses wheelchair skills that may influence users' occupational performance in their daily activities. The purpose of this study was to cross-culturally adapt the WSTQ-M-WCU 4.3 to Brazilian Portuguese and to examine the inter-rater and test-retest reliabilities. This is a methodological study of cross-cultural adaptation and psychometric properties of reliability. The agreement achieved in the cross-cultural adaptation concerning idiomatic, cultural, conceptual and semantic aspects was 100%, 99.2%, 100% and 96.18%, respectively. We analyzed the test-retest and inter-rater reliabilities in a convenience sample of 46 manual wheelchair users using Cronbach's Alpha and Bland-Altman plots. The Brazilian version has excellent internal consistency (α > 0.9) and strong inter-rater reliability (p < .05). This instrument can guide practitioners in training wheelchair skills, thus contributing to the planning of interventions and for evidence-based practice in Assistive Technology.

Wheelchair Skills Test Outcomes across Multiple Wheelchair Skills Training Bootcamp Cohorts

User training is a critical component of wheelchair service delivery to ensure individuals with a mobility impairment can negotiate environmental barriers and promote their social participation. A wheelchair "bootcamp", delivered during professional preparation education, is one strategy to better prepare occupational therapists for clinical rehabilitation practice by developing their own wheelchair skills. The purpose of this study was a retrospective review of a large dataset of student cohorts from a single site and delineate bootcamp effects on the Wheelchair Skills Test-Questionnaire (WST-Q) scores. Participant data from eight cohorts was consolidated (n = 307). Comparison of two WST-Q scoring formats revealed significantly lower scores for cohorts using the 4-point version, which was subsequently standardized to the other 3-point version. WST-Q change scores were similar between cohorts, and differences were more reflective of variability in skill level prior to bootcamp than post-bootcamp scores. Students were able to master most basic and intermediate level skills, while advanced skill acquisition was much more variable. This study provides more precise point estimates of wheelchair skill acquisition among occupational therapy students than previous studies. While confirming the benefits of bootcamp education, recommendations for further investigation were identified.

OBJECTIVE

To explore global trends in manual wheelchair service provision knowledge across geographic, professional, and socioeconomic domains.

DESIGN

A secondary analysis of a dataset from the International Society of Wheelchair Professionals' Wheelchair Service Provision Basic Knowledge Test was conducted.

SETTING

The dataset included test takers from around the world and was extracted from Test.com and International Society of Wheelchair Professionals' Wheelchair International Network.

PARTICIPANTS

2,467 unique test takers from 86 countries.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

International Society of Wheelchair Professionals' Wheelchair Service Provision Basic Knowledge Test.

RESULTS

We identified significant inverse associations between pass rate and the following variables: education (high school and some college), test taker motivation (required by academic program or employer), and country income setting (low and middle). There were significant positive associations between pass rate and the following variables: training received (offered by Mobility India or 'other NGO'), and age group served (early childhood).

CONCLUSION

Global wheelchair knowledge trends related to key variables such as training, occupation, and income setting have been preliminarily explored. Future work includes further validation of the primary outcome measure and recruitment of a larger sample size to further explore significant associations between additional test taker variables.

Impact of the TEAM Wheels eHealth manual wheelchair training program: Study protocol for a randomized controlled trial

Background

Variable, and typically inadequate, delivery of skills training following manual wheelchair (MWC) provision has a detrimental impact on user mobility and participation. Traditional in-person delivery of training by rehabilitation therapists has diminished due to cost, travel time, and most recently social distancing restrictions due to COVID-19. Effective alternative training approaches include eHealth home training applications and interactive peer-led training using experienced and proficient MWC users. An innovative TEAM Wheels program integrates app-based self-training and teleconference peer-led training using a computer tablet platform.

Objective

This protocol outlines implementation and evaluation of the TEAM Wheels training program in a randomized control trial using a wait-list control group.

Setting

The study will be implemented in a community setting in three Canadian cities.

Participants

Individuals ≥ 18 years of age within one year of transitioning to use of a MWC.

Intervention

Using a computer tablet, participants engage in three peer-led teleconference training sessions and 75–150 minutes of weekly practice using a video-based training application over 4 weeks. Peer trainers individualize the participants’ training plans and monitor their tablet-based training activity online. Control group participants also receive the intervention following a 1-month wait-list period and data collection.

Measurements

Outcomes assessing participation; skill capacity and performance; self-efficacy; mobility; and quality of life will be measured at baseline and post-treatment, and at 6-month follow-up for the treatment group.

Impact statement

We anticipate that TEAM Wheels will be successfully carried out at all sites and participants will demonstrate statistically significant improvement in the outcome measures compared with the control group.

Relationships between cognitive functioning and power wheelchair performance, confidence and life-space mobility among experienced power wheelchair users: An exploratory study

OBJECTIVES

To explore: (i) relationships between power wheelchair performance, confidence, mobility and the severity of user's cognitive impairment; (ii) relationships between cognitive functioning and power wheelchair performance, confidence and mobility; and (iii) how cognitive scores influence power wheelchair performance, confidence and mobility.

DESIGN

Cross-sectional exploratory study.

SUBJECTS

Independent power wheelchair users; ≥18 years.

OUTCOME MEASURES

Cognitive assessments (Montreal Cognitive Assessment, Motor-Free Visual Perception Test, and Dysexecutive Questionnaire) and power wheelchair driving assessments (Power mobility Indoor Driving Assessment, Wheelchair-Skills-Test-Questionnaire, and Life-Space Assessment). Analyses were completed using multivariate analysis of variance and principal component analysis.

RESULTS

There were a total of 30 participants (with a mean (SD) age of 58 (15) years, who had a mean (SD) of 3 (6.2) years of experience of power wheelchair use, (SD) and a mean score of 22 (5 on) the Montreal Cognitive Assessment. There were statistically significant differences in all power wheelchair driving assessments, depending on the severity of cognitive impairment (moderate, p = 0.009; mild, p = <0.001; none, p = 0.009). The first principal component suggested that cognitive functioning, visual perception, and performance explained 69% of the variability in the first principle componenent. The second and third principal components suggested that confidence and the built and social environments also played significant roles in power wheelchair use.

CONCLUSION

There are correlations between cognitive functioning and power wheelchair use in experienced users, with the severity of cognitive impairment influencing power wheelchair driving outcomes.

Goal attainment in mobility after acute rehabilitation of mobility-restricting paralysis syndromes with regard to the ambulatory therapeutic level of participation NeuroMoves : A German national multicenter observational cohort study

Background

A central goal of rehabilitation in patients with paralysis syndromes after stroke or spinal cord injury (SCI) is to restore independent mobility as a pedestrian or wheelchair user. However, after acute rehabilitation, the mobility frequently deteriorates in the ambulatory setting, despite the delivery of rehabilitative interventions such as physical therapy or the prescription of assistive devices. The aim of the NeuroMoves study is to identify factors that are associated with changes of mobility in the ambulatory setting after acute inpatient rehabilitation, with a particular focus on participation according to the ICF (International Classification of Functioning, Disability and Health).

Methods

The NeuroMoves study is intended as a national multicenter observational cohort study with 9 clinical sites in Germany. A total of 500 patients with mobility-restricting paralysis syndromes (i.e. stroke or SCI) are to be recruited during acute inpatient rehabilitation prior to discharge to the ambulatory setting. Patients will have 8 months of follow-up in the ambulatory setting. Three study visits at the clinical sites (baseline, midterm, and final) are planned at 4-months intervals. The baseline visit is scheduled at the end of the acute inpatient rehabilitation. During the visits, demographical data, neurological, functional, quality of life, and implementation measures will be assessed.

At baseline, each study participant receives an activity tracker (sensor for recording ambulatory mobility) along with a tablet computer for home use over the 8 months study duration. While mounted, the activity tracker records mobility data from which the daily distance covered by walking or wheelchair use can be calculated. Customized applications on the tablet computer remind the study participants to answer structured questionnaires about their health condition and treatment goals for physical therapy. Using the study participants’ tablet, therapists will be asked to answer structured questionnaires concerning treatment goals and therapeutic measures they have applied. The primary analysis concerns the association between mobility (daily distance covered) and the degree of participation-oriented rehab interventions. Further exploratory analyses are planned.

Discussion

The findings could inform healthcare decision-making regarding ambulatory care in Germany focusing on mobility-promoting interventions for patients with mobility-restricting paralysis syndromes.

Improvement and Retention of Wheelchair Skills Training for Students in Entry-Level Occupational Therapy Education

IMPORTANCE

Although an essential component of best practice, wheelchair skills training is often inadequate; occupational therapy practitioners' professional preparation is a contributing factor.

OBJECTIVE

To assess the effectiveness of a boot camp on capacity and self-efficacy in wheelchair skills and self-efficacy in clinical practice, retention of improvements, and effective boot-camp attributes.

DESIGN

Concurrent, embedded, mixed-methods cohort design that used blinded, repeated-measures quantitative evaluation with 4-mo follow-up and directed content analysis of a qualitative questionnaire.

SETTING

University entry-to-practice program.

PARTICIPANTS

Convenience sample (N = 42) of final-year students.

INTERVENTION

A 4-hr boot camp with demonstration and supervised practice. Content incorporated skill performance, training and motor-learning strategies, and safe supervision.

OUTCOMES AND MEASURES

Skill performance capacity (Wheelchair Skills Test-Questionnaire), self-efficacy with manual wheelchair use (Wheelchair Use Confidence Scale), confidence in provision of manual wheelchair training services (Self-Efficacy in Assessing, Training, and Spotting test), and a boot-camp experience questionnaire.

RESULTS

Within-subjects analysis of variance revealed significant improvements on all measures (p < .001) with large effect sizes (η_p² = .68-.88). All measures except skill capacity demonstrated retention; skill capacity decreased 5.3% (95% confidence interval [2.0, 8.5]) but was significantly higher than baseline. Three themes influenced practice confidence: knowledge acquisition, experiential learning, and client empathy.

CONCLUSIONS AND RELEVANCE

Results confirm improved wheelchair self-efficacy, capacity, and self-efficacy with clinical intervention skills. Retention of outcomes suggests the potential impact on future practice. Experiential learning supports performance component acquisition and imparts empathy of client experience, which may improve occupational therapy practitioners' perceptions of client potential.

WHAT THIS ARTICLE ADDS

A 4-hr experiential boot camp can increase students' capacity and confidence to deliver wheelchair skills training to future clients. Experiential learning increased students' appreciation for clients' experience and expectation of client potential.

Does the setting matter? Observing wheelchair transfers across different environmental conditions

The setting in which wheelchair transfers are performed can affect the difficulty and the risks associated with completion. This article presents results from an observational study involving 13 wheelchair users performing independent transfers across four settings. The aim is to understand how the environment affects how different types of independent transfers are performed. Descriptive analysis was performed alongside an objective assessment using the Transfer Assessment Instrument (TAI). The perceived difficulty reported after each transfer was also collected. Two participants exhibited radically different transferring techniques in different scenarios. Additionally, the transferring scenario was found to significantly affect the perceived difficulty of sitting transfers (toilet 2.17 ±.88; bed 1.47 ±.65, p =.001; car 1.63 ±.82, p =.012) and standing transfers (car 3.5 ±.71; bed 1 ± 0, p =.03; toilet 1 ± 0, p =.03), and the TAI score attributed to sitting pivot with use of a transfer board (couch 4.3 ±.88; bed 6.93 ± 1.29, p =.022; car 7.13 ± 1.32, p =.018). Overall, environmental constraints can lead to major technique changes and, more often, to different positioning of hands and feet which could impact the transfer's biomechanics.

Perspectives of wheelchair users with spinal cord injury on fall circumstances and fall prevention: A mixed methods approach using photovoice

Introduction

Wheelchair users with spinal cord injury are at a high risk of falls. However, the perspectives of wheelchair users with spinal cord injury on their fall circumstances and their preferences for fall prevention strategies/interventions remain understudied. Therefore, we aimed to: a) describe the circumstances of falls experienced by wheelchair users with spinal cord injury over a six-month period, b) explore their perspectives of why falls occurred in certain situations, and c) explore their perspectives on recommended content/structure of fall prevention strategies/interventions.

Methods

This sequential explanatory mixed methods study had two phases. Phase I involved tracking of falls experienced by wheelchair users with spinal cord injury over six months, in which participants completed a survey after experiencing a fall to track the number/circumstance of each fall. Data from the surveys were descriptively reported. Phase II involved a photovoice focus group discussion of the survey findings and their preferences for fall prevention strategies/interventions. Data from the focus group discussion were analyzed using a thematic analysis.

Results

Thirty-two participants completed phase I. More than half of the participants fell at least once in six months. Falls commonly occurred in the afternoon during a transfer, or when participants were wheeling over uneven ground. One-third of the falls caused an injury. Eleven participants that fell during phase I participated in the focus group. Two main themes were identified from the discussion: 1) “circumstances surrounding the falls” (e.g. when falls occurred, the home is a ‘safe space’) and 2) “suggestions and preferences for fall prevention strategies/interventions” (e.g. fall prevention involves all, fall prevention training available as needed).

Conclusion

Fall prevention strategies/interventions should be an integral component of rehabilitation practices across the lifespan. Participants recommend customizing fall prevention strategies/interventions to their specific needs to guide the structure, content, and delivery of targeted fall prevention programs.

Practice improves court mobility and self-efficacy in tennis-specific wheelchair propulsion

PURPOSE

Wheelchair tennis (WT) propulsion is uniquely characterized by the requirement for racket holding coupled with effective hand-rim contact. Thus, investigations involving strategies to enhance chair mobility skills are merited. The aim was to examine the effects of organized practice on WT match play responses and the impact of racket holding during practice.

MATERIALS AND METHODS

Following physiological profiling involving graded and peak exercise testing, 16 able-bodied (AB) participants performed bouts of WT match play interspersed with practice involving wheelchair mobility drills completed with (R) or without (NR) a tennis racket. A data logger recorded distance and speed. Self-efficacy was reported.

RESULTS AND CONCLUSIONS

Significant main effects for match revealed higher post-practice overall and forwards distances (p < 0.05), peak (p < 0.005) and average (p < 0.05) speeds and self-efficacy (SE) (p = 0.001) were attained. During practice, lower distances and speeds were achieved with R, with a lower physiological cost than NR. Practice increases court movement and SE with no associated increases in physiological cost. Changes represent enhanced court mobility. Differences between practice characteristics provide options for skill development and optimization of health outcomes.IMPLICATIONS FOR REHABILITATIONWheelchair tennis participation is likely to confer positive health effects in those with a disability or physical impairment.As chair propulsion combined with racket holding represents a complex skill challenge, novices may find the sport challenging to play.Tennis-specific mobility drills improve confidence and chair propulsion skill with likely crossover into tennis match play competence and ability.

Factors that influence the risk of falling after spinal cord injury: a qualitative photo-elicitation study with individuals that use a wheelchair as their primary means of mobility

INTRODUCTION

Falls are a concern for wheelchair users with spinal cord injury (SCI). Falls can negatively impact the physical and psychological well-being of fallers. To date, the perspectives of wheelchair users with lived experiences of SCI on the contributors to falls has been understudied. Information about factors that influence fall risk would guide the development of effective fall prevention strategies.

OBJECTIVES

To gain a comprehensive understanding of the factors that influenced the risk of falling as perceived by wheelchair users with SCI.

DESIGN

A qualitative study using photo-elicitation interviews.

SETTING

A Canadian SCI rehabilitation hospital and the participants' home/community environments.

PARTICIPANTS

Twelve wheelchair users living in the community with chronic SCI.

METHODS

Participants captured photographs of situations, places or things that they perceived increased and decreased their risk of falling. Semistructured photo-elicitation interviews were conducted to discuss the content of the photographs and explore perceptions of fall risk factors. A hybrid thematic analysis and the Biological, Behavioural, Social, Economic, and Environmental model were used as a framework to organise/synthesise the data.

RESULTS

Overall, the findings indicated that the risk of falling was individualised, complex and dynamic to each person's life situation. Four main themes were revealed in our analysis: (1) Falls and fall risk caused by multiple interacting factors; (2) Dynamic nature of fall risk; (3) Single factors were targeted to reduce falls and fall-related injuries; and (4) Fall prevention experiences and priorities.

CONCLUSIONS

Each wheelchair user encountered numerous fall risk factors in their everyday lives. Information from this study can be used to set priorities for fall prevention. Fall prevention initiatives should consider a wheelchair user's fall risks in a holistic manner, acknowledging that a person's current situation, as well as anticipating their fall risks and fall prevention needs, will change over time.

INTERnational Project for the Evaluation of "activE Rehabilitation" (inter-PEER) - a protocol for a prospective cohort study of community peer-based training programmes for people with spinal cord injury

Background

Active Rehabilitation (AR) is a community peer-based concept for people with spinal cord injury (SCI) that is primarily delivered through brief residential training programmes. Despite a plethora of positive anecdotal evidence of AR programmes as life-changing experiences, the effects of AR-programmes have not been evaluated scientifically. Here, we present the protocol of the INTERnational Project for the Evaluation of “activE Rehabilitation” (inter-PEER) aiming to evaluate the effects of AR training programmes on community-dwelling individuals with SCI.

Methods

International prospective cohort study that recruits consecutive participants in AR training programmes. Evaluation is conducted through a web-based survey at 3 time-points: at the commencement and completion of the training programme, and 3 months after the end of the training programme. Evaluation also includes a practical wheelchair skills test at the first two time-points.

The primary outcome measures are the Spinal Cord Independence Measure Self-report (SCIM-SR), the Queensland Evaluation of Wheelchair Skills test (QEWS), the Wheelchair Skills Test Questionnaire (WST-Q) and the Moorong Self-Efficacy Scale (MSES). The secondary outcome measures are the 11-item Life Satisfaction Questionnaire (LiSat-11), the Utrecht Scale for Evaluation of Rehabilitation-Participation (USER-Participation), the Leisure Time Physical Activity Questionnaire for people with SCI (LTPAQ-SCI) and the 10-item Connor-Davidson Resilience Scale (CD-RISC-10).

We piloted the implementation of the protocol in Sweden in 7 participants with diverse SCI and sociodemographic characteristics and collected feedback from participants and peer-mentors about study procedures through interviews, a workshop and field observations.

Discussion

Inter-PEER is the first initiative to propose a systematic evaluation of the effects of AR training programmes among individuals with SCI. The project is a collaborative work of multiple stakeholders, including researchers, clinicians, peer mentors with SCI, and administrators of organisations providing AR programmes. The inter-PEER uses standardised outcome measures relevant to the AR context, it will facilitate quality evaluations of community peer-based programmes, stimulate international collaborations, and inform the design of randomised controlled trials on the effects of AR training programmes.

Relationship between wheelchair skills scores and peak aerobic exercise capacity of manual wheelchair users with spinal cord injury: a cross-sectional study

Purpose: Although both wheelchair skills and fitness are important and probably inter-related, the extent and nature of the relationship between them are not well understood. The objective of this study was to test the hypothesis that there are significant relationships between wheelchair skills scores and the peak exercise capacity of community-dwelling manual wheelchair users with spinal cord injury.Materials and methods: We studied 26 participants, recording Wheelchair Skills Test Questionnaire scores and peak power output from graded aerobic wheelchair exercise testing on a motorized treadmill.Results: The median Wheelchair Skills Test Questionnaire capacity, confidence, and performance scores were 83.3%, 81.5%, and 76.7% and the median peak power output was 58.2 W. On regression analysis, there were significant relationships between the total Wheelchair Skills Test Questionnaire capacity, confidence, and performance scores and peak power output (R² 0.270-0.709, odds ratios 1.043-1.150, p < 0.05).Conclusions: Significant relationships exist between the wheelchair skills capacity, confidence, and performance scores and the peak exercise capacity of community-dwelling manual wheelchair users with spinal cord injury. These findings suggest that both wheelchair skills training and exercise training may be useful during the rehabilitation of people with spinal cord injury.Implications for rehabilitationModerate positive relationships exist between wheelchair skills capacity and the peak exercise capacity of community-dwelling manual wheelchair users with spinal cord injury.Moderate positive relationships exist between wheelchair skills confidence and the peak exercise capacity of community-dwelling manual wheelchair users with spinal cord injury.Although further research is needed, these findings suggest that clinicians should address both wheelchair skills training and exercise training during the rehabilitation of people with spinal cord injury and not assume that either alone is sufficient.

Wheelchair skills training for occupational therapy students: comparison of university-course versus "boot-camp" approaches

Objective: To test the hypothesis that occupational therapy students who receive wheelchair skills training education using a distributed-practice university-course approach versus a condensed-practice boot-camp approach results in greater improvements post-intervention in relevant outcomes. Design: A quasi-experimental, nonequivalent control group design. Setting: A university occupational therapy program. Participants: Occupational therapy students (experimental group) and recent occupational therapy graduates (control group) (N = 58). Interventions: A 15-week, 45-hour wheelchair provision course in which a total of 24 hours were dedicated to wheelchair skills testing and training education (experimental group) versus an 8-hour wheelchair skills training boot-camp (control group). Main outcome measures: Assessments were conducted pre- and post-intervention using the Wheelchair Skills Test Questionnaire (WST-Q), Wheelchair Use Confidence Scale for Manual Wheelchair Users (WheelCon) and Self-Efficacy on Assessing, Training and Spotting wheelchair skills (SEATS). Results: Compared to baseline, the WST-Q, WheelCon and SEATS scores improved significantly for both groups (p < .001). There were no significant differences in change scores (post-intervention - baseline values) between the groups for WST-Q, WheelCon or SEATS scores, however, the experimental group demonstrated a trend (p < .051) of higher scores for all outcome measures. Conclusions: Occupational therapy students who received wheelchair skills training using either a distributed-practice university-course or condensed-practice boot-camp approach demonstrated significant post-training improvements in their WST-Q, WheelCon and SEATS scores, but no significant differences were found between groups. Implications for Rehabilitation Both a distributed-practice university-course approach and a condensed-practice bootcamp approach for training wheelchair skills to occupational therapy students results in large post-intervention improvements in wheelchair skill, wheelchair confidence and self-efficacy to test, train, spot and document wheelchair skills. The pre-education (optional course) wheelchair skill, wheelchair confidence and self-efficacy to test, train, spot and document wheelchair skills scores found in this cohort of occupational therapy students confirms the need to include this wheelchair content in mandatory occupational therapy curricula.

Two independent reviewers screened articles and extracted data. Methodological quality was assessed using Cochrane's Risk of Bias Tool.

DATA SYNTHESIS

Meta-analyses (including sub-group analyses) were conducted for the Wheelchair Skills Test (WST) and WST Questionnaire (WST-Q) total capacity scores. We qualitatively assessed retention, WST/WST-Q subtotal and individual-skill capacity scores and other identified outcomes. The quality of evidence was determined using the Grades of Recommendation, Assessment, Development and Evaluation (GRADE) approach. Thirteen articles (581 participants) were included for analysis. The level of evidence was of moderate quality. The WSTP increased the post-training WST/WST-Q total capacity scores by 14.0% (95% CI: 7.4, 20.8; p < .0001) compared to no treatment, standard care or educational controls, a relative increase over baseline of 21.2%. Subgroup analyses showed that training was more effective for new wheelchair users. Retention of training effects was suggested by the absence of significant declines between tests post-training and at follow-up. The WSTP was found to have positive effects on some other outcomes. No serious adverse events were reported.

CONCLUSIONS

There is moderate quality evidence that the WSTP is a safe intervention that has a clinically meaningful effect on WST/WST-Q capacity scores and some other outcomes. Implications for rehabilitation A systematic review and meta-analysis of 13 randomized controlled trials on a total of 581 participants, using the Wheelchair Skills Training Program (WSTP) as the intervention, found that the WSTP increased Wheelchair Skills Test (WST) and WST Questionnaire (WST-Q) total capacity scores by 21.2% relative to baseline. Subgroup analyses showed that training was more effective for new wheelchair users. The WSTP was found to have positive effects on some other outcomes and no serious adverse events were reported. The WSTP warrants cautious implementation in clinical and educational settings.

A randomized control trial feasibility evaluation of an mHealth intervention for wheelchair skill training among middle-aged and older adults

BACKGROUND

Providing mobility skills training to manual wheelchair (MWC) users can have a positive impact on community participation, confidence and quality of life. Often such training is restricted or not provided at all because of the expense of, and limited access to, occupational and physical therapists before and after discharge. This is particularly true among middle-aged and older adults, who often have limited access to rehabilitation services and require more time to learn motor skills. A monitored MWC skills training home program, delivered using a computer tablet (mHealth), was developed as an alternative approach to service delivery. The purpose of this study was to evaluate the feasibility of implementing this mHealth MWC skills training program among middle-aged and older adults.

METHODS

A 2 × 2 factorial design randomized controlled trial (RCT) was used to compare the mHealth intervention and control groups, with additional wheeling time as a second factor. Community-dwelling MWC users aged 55 and older, who had used their MWC for less than two years and propelled with two hands, were recruited. Feasibility outcomes related to process, resources, management and treatment criteria were collected.

RESULTS

Eighteen participants were recruited, with a retention rate of 94%. Mean (±SD) duration for the first and second in-person training sessions were 90.1 ± 20.5 and 62.1 ± 5.5 min, respectively. In the treatment group, 78% achieved the minimum amount of home training (i.e., 300 min) over four weeks and 56% achieved the preferred training threshold (i.e., 600 min). Trainers reported only seven minor protocol deviations. No tablets were lost or damaged and there was one incident of tablet malfunction. No injuries or adverse incidents were reported during data collection or training activities. Participants indicated 98% agreement on the post-treatment benefit questionnaire.

DISCUSSION

Overall, the study protocol enabled implementation of the intervention in a safe, efficient and acceptable manner. Participant recruitment proved to be challenging, particularly gaining access to individuals who might benefit. Resource issue demands were acceptable for administration of the intervention; data collection was more time-consuming than anticipated but could be reduced with minor revisions. Participant retention and home program treatment adherence was high; both participant and trainer burden was acceptable. Treatment group participants reported a positive experience and clinical benefits from training program. The findings suggest a full-scale RCT evaluating the clinical impact of the Enhancing Participation In the Community by improving Wheelchair Skills (EPIC Wheels) intervention is warranted, provided the recruitment issues are addressed through collaborative partnerships and active recruitment strategies.

Feasibility of the trial procedures for a randomized controlled trial of a community-based peer-led wheelchair training program for older adults

BACKGROUND

A novel peer-led manual wheelchair (MWC) training program may support the training needs of older adults, but establishing program feasibility is a pragmatic first step. The purpose of this study was to evaluate the feasibility of a peer-led Wheelchair training Self-Efficacy Enhanced for Use (WheelSeeU) program.

METHODS

Forty MWC users (mean age 65 years) were randomly assigned to the experimental (WheelSeeU) or control group. Feasibility indicators of process, resources, management, and safety were collected throughout the study.

RESULTS

The consent rate was 49%. Participant retention rate was 90% post-intervention and 87.5% at follow-up (6 months). All participants reported perceived benefits from WheelSeeU. Participants and trainers adhered to the study protocol (>90%), and fidelity of the WheelSeeU intervention was attained (>90%). There were no adverse events.

CONCLUSIONS

WheelSeeU is an innovative and feasible approach for providing MWC training to older adults that is accessible beyond initial rehabilitation without increased clinician burden. With minor modifications, it is feasible that WheelSeeU can be administered to older adults living in the community.

Measurement properties of the Wheelchair Skills Test for scooters among experienced users

PURPOSE

To investigate the score distribution, reliability, and validity of the objective Wheelchair Skills Test (WST) for scooter users.

METHOD

A study using a test-retest design was conducted with 20 people who had mobility limitations that prevented them from ambulating more than one city block without a mobility aid, and who had owned a scooter for ≥3 months. Objective scooter skills, confidence, and physical accessibility were measured at both time points, while anxiety, depression, visual attention and task switching, functional independence, and visual acuity were measured only at baseline.

RESULTS

The mean total WST scores at Time 1 and Time 2 were 86.3% and 87.5%. The WST ICC was 0.889. The WST had a SEM of 2.50 and a Cronbach's alpha of 0.74. The total WST scores were significantly correlated with total subjective WST-Q scores (r = 0.547, p = 0.013), scooter confidence (r = 0.466, p = 0.038), and were affected by gender (p = 0.005).

CONCLUSION

The WST for scooters has good test-retest reliability and generally varies as anticipated with other measures. Although further study is needed, the WST for scooters appears to have promise for use in research and clinical practice. Implications for Rehabilitation It is important to understand the measurement properties of the tools we use in rehabilitation so the results can be interpreted correctly. As scooter use increases, better measurement of skills is required.

Wheelchair Skills Capacity and Performance of Manual Wheelchair Users With Spinal Cord Injury

OBJECTIVES

To describe the wheelchair skills capacity and performance of experienced manual wheelchair users with spinal cord injury (SCI) and to assess measurement properties of the Wheelchair Skills Test (WST) and Wheelchair Skills Test Questionnaire (WST-Q).

DESIGN

Cross-sectional descriptive study involving within-subject comparisons.

SETTING

Four Spinal Cord Injury Model Systems centers.

PARTICIPANTS

Manual wheelchair users with SCI (N=117).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

WST and WST-Q version 4.2 as well as measures for Confidence, Basic Mobility, Independence, Ability to Participate, Satisfaction, and Pain Interference.

RESULTS

The median (interquartile range) values for WST capacity, WST-Q capacity, and WST-Q performance were 81.0% (69.0%-90.0%), 88.0% (77.0%-97.0%), and 76.0% (66.3%-84.0%). The total WST capacity scores correlated significantly with the total WST-Q capacity scores (r=.76; P<.01) and WST-Q performance scores (r=.55; P<.01). The total WST-Q capacity and WST-Q performance scores were correlated significantly (r=.63; P<.001). Success rates were <75% for 10 of the 32 (31%) individual skills on the WST and 6 of the 32 (19%) individual skills on the WST-Q. Regression models for the total WST and WST-Q measures identified statistically significant predictors including age, sex, body mass index, and/or level of injury. The WST and WST-Q measures correlated significantly with the Confidence, Basic Mobility, Independence, or Pain Interference measures.

CONCLUSIONS

Many people with SCI are unable to or do not perform some of the wheelchair skills that would allow them to participate more fully. More wheelchair skills training may enhance participation and quality of life of adults with SCI. The WST and WST-Q exhibit good content, construct, and concurrent validity.

Wheeled mobility skills of wheelchair basketball players: a randomized controlled study

PURPOSE

The aim of this study was to assess the influence of wheelchair basketball sport on the functional abilities of wheelchair users.

METHOD

This is a randomized controlled study. Wheelchair basketball players (n = 111) and non-player (n = 85) were included in this study. We administered the questionnaire version of the wheelchair skills test questionnaire (WST_Q), recording the participants' capacity and performance scores on each of 32 skills.

RESULTS

Player group have the baseline values of WST_Q higher than control group. The mean total percentage score of player group was significantly greater than control group (p < 0.05). The get over 15 cm level (respectively, rations of capacity and performance of groups: player/control: 50.5-20% and 54.1-24.7%) and the ascends 10° incline (player/control 96.4-48.2% and 98.2-54.1%).

CONCLUSIONS

Participation in regular wheelchair basketball sport may preserve and augment functional abilities in with wheelchair user Implications for rehabilitation The skills-sports relationship is reciprocal. With increased wheelchair skills, people may be more inclined to engage in sports; subsequently, with greater sports, wheelchair skills could improve. Wheelchair mobility skills during clinical rehabilitation should reflect the daily activities and needs of each wheelchair user. WST-Q provides advantages in terms of requiring less time and material in using of clinical.

The impact of the World Health Organization 8-steps in wheelchair service provision in wheelchair users in a less resourced setting: a cohort study in Indonesia

Background

For people who have a mobility impairment, access to an appropriate wheelchair is an important step towards social inclusion and participation. The World Health Organization Guidelines for the Provision of Manual Wheelchairs in Less Resourced Settings emphasize the eight critical steps for appropriate wheelchair services, which include: referral, assessment, prescription, funding and ordering, product preparation,fitting and adjusting, user training, and follow-up and maintenance/repairs. The purpose of this study was to investigate how the provision of wheelchairs according to the World Health Organization’s service provision process by United Cerebral Palsy Wheels for Humanity in Indonesia affects wheelchair recipients compared to wait-listed controls.

Methods

This study used a convenience sample (N = 344) of Children, Children with proxies, Adults, and Adults with proxies who were on a waiting list to receive a wheelchair as well as those who received one. Interviews were conducted at baseline and a 6 month follow-up to collect the following data: Demographics and wheelchair use questions, the World Health Organization Quality of Life-BREF, Functional Mobility Assessment, Craig Handicap Assessment Recording Technique Short Form. The Wheelchair Assessment Checklist and Wheelchair Skills Test Questionnaire were administered at follow up only.

Results

167 participants were on the waiting list and 142 received a wheelchair. Physical health domain in the World Health Organization Quality of Life-BREF improved significantly for women who received a wheelchair (p = 0.044) and environmental health improved significantly for women and men who received a wheelchair as compared to those on the waiting list (p < 0.017). Satisfaction with the mobility device improved significantly for Adults with proxies and Children with proxies as compared to the waiting list (p < 0.022). Only 11 % of Adults who received a wheelchair reported being able to perform a “wheelie”. The condition of Roughrider wheelchairs was significantly better than the condition of kids wheelchairs for Children with proxies as measured by the Wheelchair Assessment Checklist (p = 0.019).

Conclusions

Wheelchair provision according to World Health Organization’s 8-Steps in a less-resourced setting has a range of positive outcomes including increased satisfaction with the mobility device and better quality of life. Wheelchair provision service could be improved by providing more hours of wheelchair skills training. There is a need for outcome measures that are validated across cultures and languages.

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.

Prevalence of low mobility and self-management self-efficacy in manual wheelchair users and the association with wheelchair skills

OBJECTIVE

To estimate the prevalence of low wheelchair-mobility and self-management self-efficacy and to evaluate the association with wheelchair skills.

DESIGN

Cross-sectional.

SETTING

Community.

PARTICIPANTS

Community-dwelling manual wheelchair users (N=123) who were ≥50 years of age (mean, 59.7±7.5y) and from British Columbia and Quebec, Canada.

INTERVENTIONS

None.

MAIN OUTCOME MEASURES

The 13-item mobility and 8-item self-management subscales from the Wheelchair Use Confidence Scale-Short Form (standardized scores range, 0-100) measured self-efficacy, and the 32-item Wheelchair Skills Test, Questionnaire Version (scores range, 0-100) measured wheelchair skills. A score of 50 was used to differentiate individuals with high and low self-efficacy, and a score of 72 differentiated between high and low wheelchair skills.

RESULTS

The prevalence of low wheelchair-mobility and self-management self-efficacy was 28.5% (95% confidence interval [CI], 20.6-36.4) and 11.4% (95% CI, 5.8-17.0), respectively, and their bivariate association with wheelchair skills was r=.70 and r=.39, respectively. Of the sample, 16% reported conflicting mobility self-efficacy and skill scores; 25% reported low self-efficacy and high skills. Of the participants, 30% reported conflicting scores between self-management self-efficacy and wheelchair skills, with 8.1% reporting lower self-efficacy than skill.

CONCLUSIONS

Low self-efficacy was relatively high in this sample as was its discordance with wheelchair skills. Interventions to address low self-efficacy and/or offset the discordant self-efficacy/skill profiles are warranted.

Randomized controlled trial protocol feasibility: The Wheelchair Self-Efficacy Enhanced for Use (WheelSeeU)

BACKGROUND

Manual wheelchairs (MWCs) can improve mobility and social participation for individuals who experience difficulty walking; however, older adults receive little training for wheelchair use. The Wheelchair Self-Efficacy Enhanced for Use (WheelSeeU) research program provides peer-led training that may positively influence wheelchair use while reducing clinician burden.

PURPOSE

The purpose of this study is to evaluate the feasibility and clinical outcomes of WheelSeeU.

METHOD

A randomized control trial (RCT) recruits and randomly assigns 40 MWC users (55+ years). Feasibility indicators assessing process, resource, management, and treatment issues are measured, and clinical outcomes (wheelchair skills, safety, confidence, mobility, social participation, quality of life, health utility) are collected at three time points.

IMPLICATIONS

WheelSeeU provides an innovative approach for teaching wheelchair skills to an aging population that may improve wheelchair use and decrease clinician burden. Since RCTs are expensive and challenging in rehabilitation, establishing feasibility prior to larger effectiveness trials is prudent.

Comparison between performances of three types of manual wheelchairs often distributed in low-resource settings

PURPOSE

This study was conducted to compare the performance of three types of chairs in a low-resource setting. The larger goal was to provide information which will enable more effective use of limited funds by wheelchair manufacturers and suppliers in low-resource settings.

METHODS

The Motivation Rough Terrain and Whirlwind Rough Rider were compared in six skills tests which participants completed in one wheelchair type and then a day later in the other. A hospital-style folding transport wheelchair was also included in one test. For all skills, participants rated the ease or difficulty on a visual analogue scale. For all tracks, distance traveled and the physiological cost index were recorded. Data were analyzed using repeated measures analysis of variance.

RESULTS

The Motivation wheelchair outperformed Whirlwind wheelchair on rough and smooth tracks, and in some metrics on the tight spaces track. Motivation and Whirlwind wheelchairs significantly outperformed the hospital transport wheelchair in all metrics on the rough track skills test.

CONCLUSION

This comparative study provides data that are valuable for manufacturers and for those who provide wheelchairs to users. The comparison with the hospital-style transport chair confirms the cost to users of inappropriate wheelchair provision. Implications for Rehabilitation For those with compromised lower limb function, wheelchairs are essential to enable full participation and improved quality of life. Therefore, provision of wheelchairs which effectively enable mobility in the cultures and environments in which people with disabilities live is crucial. This includes low-resource settings where the need for appropriate seating is especially urgent. A repeated measures study to measure wheelchair performances in everyday skills in the setting where wheelchairs are used gives information on the quality of mobility provided by those wheelchairs. This study highlights differences in the performance of three types of wheelchairs often distributed in low-resource settings. This information can improve mobility for wheelchair users in those settings by enabling wheelchair manufacturers to optimize wheelchair design and providers to optimize the use of limited funds.

Measurement properties of the Wheelchair Skills Test-Questionnaire for powered wheelchair users

PURPOSE

To evaluate the test-retest reliability, concurrent validity and responsiveness of the Wheelchair Skills Test - Questionnaire (WST-Q) Version 4.1 for powered wheelchair users.

METHODS

A volunteer sample of 72 community-dwelling, experienced powered wheelchair users, ranging in age from 50 to 77 years, participated in this study. Participants completed measures at baseline and 1 month later.

RESULTS

Mean ± standard deviation total percentage WST-Q scores at baseline and 1 month were 83.7% ± 10.9 and 86.3% ± 10.0 respectively. Cronbach's alpha was 0.90 and the 1 month test-retest intraclass correlation coefficient (ICC1,1) was 0.78 (confidence interval: 0.68-0.86). There were no floor or ceiling effects. Percentages of agreement between baseline and 1 month for individual skills ranged from 72.2% to 100%. The correlations between the WST-Q and the objective Wheelchair Skills Test (WST), WheelCon and Life Space Assessment were r = 0.65, r = 0.47 and r = 0.47 respectively. The standard error of measurement (SEM) and smallest real difference (SRD) were 5.0 and 6.2 respectively.

CONCLUSION

The WST-Q 4.1 has high internal consistency, strong test-retest reliability and strong support for concurrent validity and responsiveness.

IMPLICATIONS FOR REHABILITATION

There is evidence of reliability, validity and responsiveness of the Wheelchair Skills Test - Questionnaire (WST-Q) among experienced older adult powered wheelchair users. The WST-Q can be used to measure powered wheelchair skills, guide intervention and measure change over time.

Influences of wheelchair-related efficacy on life-space mobility in adults who use a wheelchair and live in the community

BACKGROUND

Self-efficacy has important implications for health and functioning in people with limited mobility. However, the influence of self-efficacy on mobility in adults who use wheelchairs has yet to be investigated.

OBJECTIVE

The study objective was to: (1) estimate the direct association between wheelchair use self-efficacy and life-space mobility and (2) investigate an indirect effect through wheelchair skills.

DESIGN

This was a cross-sectional study.

METHODS

Participants (N=124) were adults who use a wheelchair, live in the community, and were 50 years of age and older (X̅=59.67, range=50-84), with at least 6 months of experience with manual wheelchair use; 60% were men. The 20-item Life-Space Assessment, the 65-item Wheelchair Use Confidence Scale, and the 32-item Wheelchair Skills Test-Questionnaire were used to measure life-space mobility, self-efficacy, and wheelchair skills, respectively.

RESULTS

Self-efficacy had a statistically significant association with life-space mobility (nonstandardized regression coefficient=0.23, 95% confidence interval=0.07, 0.39) after controlling for sex, number of comorbidities, geographic location, and assistance with using a wheelchair. This model accounted for 37.1% of the life-space mobility variance, and the unique contribution of self-efficacy was 3.5%. The indirect effect through wheelchair skills was also statistically significant (point estimate=0.21, 95% bootstrapped confidence interval=0.05, 0.43) and accounted for 91.3% of the direct effect of self-efficacy on life-space mobility. This model accounted for 39.2% of the life-space mobility variance.

LIMITATIONS

Causality could not be established because of the study design. The self-report nature of data from volunteers may be influenced by recall bias, social desirability, or both.

CONCLUSIONS

Wheelchair use self-efficacy had both direct and indirect associations with life-space mobility after controlling for confounding variables. Interventions targeted toward improving self-efficacy may lead to improvements in life-space mobility.

Development of a novel evidence-based automated powered mobility device competency assessment

This paper describes the outcomes of a clinical study to assess the validity of a stand-alone sensor package and algorithms to aid the assessment by an occupational therapist (OT) whether a person has the capacity to safely and effectively operate a powered mobility device such as a wheelchair in their daily activities. The proposed solution consists of a suite of sensors capable of inferring navigational characteristics from the platform it is attached to (e.g. trajectories, map of surroundings, speeds, distance to doors, etc). Such information presents occupational therapists with the ability to augment their own observations and assessments with correlated, quantitative, evidence-based data acquired with the sensor array. Furthermore, OT reviews can take place at the therapist's discretion as the data from the trials is logged. Results from a clinical evaluation of the proposed approach, taking as reference the commonly-used Power-Mobility Indoor Driving Assessment (PIDA) assessment, were conducted at the premises of the Prince of Wales (PoW) Hospital in Sydney by four users, showing consistency with the OT scores, and setting the scene to a larger study with wider targeted participation.
