Psychometric properties of the International Society of Wheelchair Professionals' basic manual wheelchair-service-provision knowledge Test Version 1 and development of Version 2.

INTRODUCTION: Valid and reliable scores from measurement tools to test competency in basic manual wheelchair-service-provision are needed to promote good practice and support capacity building. The International Society of Wheelchair Professionals' (ISWP) Basic Test Version 1 in English, launched in 2015, is the most frequently used outcome measure tool to test basic manual wheelchair-service-provision knowledge and is part of an international certification process. Despite the wide acceptance and use of the test, its psychometric properties have not yet been established. The objectives of this study were 1) to evaluate the test's psychometric properties, 2) to develop the test's Version 2, and 3) to evaluate the content validity of the new version. METHODS: For Objective 1, methods from the Classical Test Theory were used to obtain items' difficulty, item discrimination index and domains' reliability. For Objective 2, a team of experts in wheelchair service delivery and education conducted a systematic qualitative review of the questions' text and answers and updated them using evidence-based guidelines. For Objective 3, an external team reviewed the clarity, relevance and domain allocation of the developed items using a 4-point Likert scale. Descriptive statistics were used to describe and characterize the results for each objective. Item-content (I-CVI) and Scale-content (S-CVI) validity indexes were calculated to compute content validity. RESULTS: For Objective 1, all domains in the test were below the threshold for acceptable internal consistency reliability; 80% of the total test pool (116 items from the total pool of 145) did not meet the thresholds for item difficulty and index of discrimination suggested in the literature. Of the items in the Test, 78% could be responded to intuitively and 66% did not distinguish between test-takers who were knowledgeable in the content area and those who were not. For Objective 2, experts found concerns such as items being grouped in the wrong domain, being repeated, not using person-first language, and using terms inconsistently. Thirty-four (23.4%) items were dropped and 111 (76.5%) were updated. In addition, 61 new items were developed. Members re-categorized the items and proposed a new classification of subdomains. For Objective 3, good agreement between subject-matter experts was found; the S-CVI calculated using the I-CVIs related to item clarity was 84% while using the I-CVIs related to item relevance was 98%. Only 7 items (4.1%) were deemed to be in the wrong domain and 4 items (2.3%) were considered irrelevant and dropped. CONCLUSION: The psychometric evidence in support of ISWP Basic Test Version 1 in English is suboptimal. A new set of items developed by experts in the field has shown excellent content validity. Ongoing assessments will be needed as ISWP Basic Test Version 2 is implemented and monitored.

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.

Wheelchair service provision education for healthcare professional students, healthcare personnel and educators across low- to high-resourced settings: a scoping review.

PURPOSE: This review aimed to collate and summarize available research literature about wheelchair service provision education available to healthcare professional students, healthcare personnel and educators across low- to high-resourced settings. METHODS: The Joanna Briggs Institute methodological steps for scoping reviews were followed. Included studies were mainly sourced from Medline, Embase, CINAHL, Scopus, Academic Search Complete and ProQuest. Independent title, abstract and full-text screening with defined inclusion and exclusion criteria was performed. All screening and extraction were performed independently by two authors. A thematic approach was used to synthesize results. Data extracted from included studies were charted according to a template that we created. The study quality was also appraised. RESULTS: A total of 25 articles were included (11, 36% from high-income settings) with 12 (48%) observational studies and 13 (52%) experimental studies. The literature addressed three main topics: (1) assessing wheelchair service provision knowledge, (2) implementing training interventions using in-person, online and/or hybrid learning approaches and (3) describing current wheelchair service provision education globally. The most frequently reported training programs used were the Wheelchair Skills Program and the World Health Organization Wheelchair Service Training Package - Basic Level. CONCLUSION: Limited information has been published about the integration of wheelchair content into the curricula of professional rehabilitation programs. Efforts to build international partnerships, improve the quality and currency of training programs and build resources that can assist educators in the integration of wheelchair-related content into professional rehabilitation programs should be prioritized.Implications for RehabilitationThis is the first review that examined and synthesized the current state of wheelchair service provision education for rehabilitation students and personnel across low- to high-income countries.Findings from this review indicate that there is limited information about the integration of wheelchair-related content into professional rehabilitation programs.Efforts to build international partnerships, standardize wheelchair service provision content and evaluation and integrate training into professional rehabilitation programs worldwide should be prioritized.

Wheelchair service provision education for healthcare professional students, healthcare personnel and educators across low- to high-resourced settings: a scoping review protocol.

PURPOSE: Appropriate wheelchair provision is necessary for addressing participation barriers experienced by individuals with mobility impairments. Health care professionals involved in the wheelchair service provision process require a specific set of skills and knowledge to enable wheelchair use that meets individual posture, mobility and daily living requirements. However, inconsistencies exist in academic programmes globally about providing comprehensive education and training programmes. The planned scoping review aims to review and synthesize the global literature on wheelchair service provision education for healthcare professional students, healthcare personnel and educators offered by universities, organizations and industries. METHODS: This scoping review will be guided by the Joanna Briggs Institute (JBI) methodological framework. Comprehensive literature searches will be conducted on various global electronic databases on health to seek out how wheelchair service provision education is organized, integrated, implemented and evaluated. Two independent reviewers will perform eligibility decisions and key data extractions. Data from selected studies will be extracted and analysed using conventional content analysis. Information related to wheelchair service provision education including curriculum development, content, teaching methods, evaluation and models of integration will be synthesized. IMPLICATIONS AND DISSEMINATION: The planned scoping review will be the first to examine all aspects of wheelchair service provision education across professionals, settings and countries. We anticipate that results will inform the content of a Wheelchair Educators' Package, and if appropriate, a follow-up systematic review. An article reporting the results of the scoping review will be submitted for publication to a scientific journal.Implications for RehabilitationA comprehensive examination of wheelchair service provision education could help develop strategies to address the unmet need for wheelchair services globally.Findings for this review will facilitate the planning and development of an evidence-based education package that could bridge the existing knowledge gaps related to safe and effective wheelchair service provision among health professionals involved.This review will also inform the potential barriers and enablers for effective integration and implementation of wheelchair service provision education worldwide.

Accelerated wear testing shows that thermoplastic bushings could be a cost-effective and durable alternative to traditional bearings for wheelchair caster use.

Introduction: Wheelchair caster bearings often suffer high-risk failures that lead to adverse consequences such as user injuries, suggesting that design improvements are necessary. This study aimed to compare thermoplastic bushings to standard roller bearings for potential improvements in durability and cost-effectiveness. Methods: The durability and cost-effectiveness of two thermoplastic bushing models and two metallic ball-bearing models were tested using a standard lab-based accelerated wear testing protocol. Bushings and bearings were installed on a standard 8″ caster, and four samples per model underwent testing (16 total samples). Results: All failures were experienced by the stem rolling element. The thermoplastic bushings experienced higher mean durability than the standard ball-bearings. There were significant differences in durability across the tested models, F(3,12) = 3.88, p = 0.04. The durability of thermoplastic bushing #2 was higher than the standard type ZZ shielded deep groove ball bearings, p < 0.05. There were significant differences in cost-effectiveness across the tested models, F(3,12) = 7.64, p = 0.004. The cost-effectiveness of both thermoplastic bushings were significantly higher compared to type 2RS sealed deep groove bearings, p < 0.05. Conclusions: The use of thermoplastic bushings can lower product cost and potentially reduce caster failures in the community that are associated with adverse consequences including user injuries.

Older Wheelchair Users Recommend Age-Friendly Design Improvements to a Wheelchair Maintenance App: Mixed Methods Development Study.

BACKGROUND: Wheelchair part failures have doubled over the past decade. Preventative wheelchair maintenance reduces wheelchair failures and prevents user consequences. We are developing a smartphone app called WheelTrak, which alerts users when maintenance is required, to encourage maintenance practices and compliance. OBJECTIVE: This mixed methods study aimed to develop a wheelchair maintenance app using broad stakeholder advice and investigate older adults' interaction experience with the app and their perceived barriers to and facilitators of maintenance. METHODS: Interviews were conducted with stakeholders, including mobility device users, to generate needs statements and app specifications. The app was designed in 2 stages. Stage 1 involved the development of the app according to the specifications and evaluation of the app interface by lead users. Stage 2 included the revision of the app screens and manual functionality testing. Usability testing and semistructured interviews were conducted with older wheelchair and scooter users. The System Usability Scale was used to measure app usability. RESULTS: Interviews with power and manual wheelchair users (37/57, 65%), wheelchair service providers (15/57, 26%), manufacturers (2/57, 4%), seating and mobility researchers (1/57, 2%), and insurance plan providers (2/57, 4%) informed the needs and specifications of the app technology. The 2-stage development process delivered a fully functional app that met the design specifications. In total, 12 older adults (mean age 74.2, SD 9.1 years; n=10, 83% women; and n=2, 17% men) participated in the usability testing study. Of the 12 participants, 9 (75%) agreed to use WheelTrak for preventative maintenance. WheelTrak scored an average System Usability Scale score of 60.25 (SD 16). Four overarching themes were identified: WheelTrak app improvements, barriers to maintenance, consequences related to mobility device failure, and smart technology use and acceptance. Older adults preferred the simplicity, readability, personalization, and availability of educational resources in the app. Barriers to maintenance pertained to health issues and lack of maintenance knowledge among older adults. Facilitators of maintenance included notification for maintenance, app connectivity with the service provider, reporting of device failure, and the presence of a caregiver for maintenance. CONCLUSIONS: This study highlighted age-friendly design improvements to the app, making it easy to be used and adopted by older wheelchair users. The WheelTrak app has close to average system usability. Additional usability testing will be conducted following app revision in the future.

Community-based wheelchair caster failures call for improvements in quality and increased frequency of preventative maintenance.

STUDY DESIGN: Secondary data analysis of wheelchair failures and service repair logs from a network of wheelchair suppliers. OBJECTIVE: To determine the frequency of wheelchair caster failures and service repairs across wheelchair manufacturers and models and investigate the relationships between them. SETTING: Wheelchair caster failures and service repairs occurred in the community. METHODS: Reported caster failure types were classified based on the risk they pose for user injuries and wheelchair damage. Caster failures experienced by users of tilt-in-space and ultralightweight manual wheelchair models and Group 2, 3 and 4 power wheelchair models between January 2017 and October 2019 were analyzed using Chi-Square tests for independence. Correlational analysis of failures and service repairs was performed. RESULTS: A total of 6470 failures and 151 service repairs reported across four manufacturers and five models were analyzed. Failure types were significantly associated with manufacturers and models, respectively. Users of tilt-in-space wheelchairs, who require greater seating support, experienced twice the proportion of high-risk caster failures than the ultralightweight manual wheelchair users. Similarly, Group 3 and 4 power wheelchair users, who have complex rehabilitation needs, experienced 15-36% more high-risk failures than Group 2 users. Service repairs negatively correlated with high-risk manual wheelchair caster failures. CONCLUSIONS: Wheelchair users who have greater seating and complex rehabilitation needs are at a higher risk for sustaining injuries and secondary health complications due to frequent caster failures. The study findings call for significant reforms in product quality and preventative maintenance practices that can reduce wheelchair failures and user consequences.

Development and efficacy of an online wheelchair maintenance training program for wheelchair personnel.

OBJECTIVES: To develop an online version of the wheelchair maintenance training program (WMTP) and compare learning outcomes from the in-person and online programs using the wheelchair maintenance training questionnaire (WMT-Q), administered before and after the intervention. DESIGN: Iterative development of an online version of the WMTP and implementation. SETTING: Online. PARTICIPANTS: 26 graduate and undergraduate students. INTERVENTION: Web-based training. These results are compared with those from another study of the in-person WMTP with 10 participants. MAIN OUTCOME MEASURES: Feedback survey and WMT-Q. RESULTS: The training program was well-received and valued by all 26 participants. A significant increase in all scores after the online training program was found, based on pre-/post-intervention scores. In manual wheelchair open-ended questions, knowledge increased from 16% to 21%, p < .05; in power wheelchair open-ended questions, from 9% to 31%, p < .05; in multiple-choice questions related to knowledge, from 27% to 59%, p < .05; confidence increased from 8% to 80%, p < .05; and capacity from 12% to 88%, p < .05. There was no statistical difference in WMT-Q scores between individuals who participated in the in-person and online programs. CONCLUSION: This study indicates that there was a similar-increased knowledge for participants, indicating that web-based training may be a viable approach for delivering maintenance training.

Development of a toolkit for educators of the wheelchair service provision process: the Seating and Mobility Academic Resource Toolkit (SMART).

BACKGROUND: Insufficient wheelchair training among rehabilitation professionals has been identified as an important factor that hinders access to appropriate wheelchair services. The aim of this study was to develop a toolkit to promote the integration of wheelchair education into academic curricula of rehabilitation programs. METHODS: A participatory action research design was carried out in three phases: (1) development of the Initial and Alpha Versions involving secondary analyses of surveys (n = 72), interviews (n = 14), and academic training partners meeting presentations (n = 16); (2) development of the Beta Version based on feedback from collaborators (n = 21); and (3) development of the Launch Version based on feedback from participants attending presentations of the Beta Version at conferences, symposiums, and webinars (n = 94). RESULTS: Over 100 individuals participated in reviews of the Seating and Mobility Academic Resource Toolkit (SMART). Initial development addressed modifiable factors that perpetuate insufficient wheelchair education in academic curricula (e.g., limited awareness, limited expertise). Internal feedback on the web-based Alpha Version resulted in modifications of appearance and multimedia, structure and design, and navigation. External feedback then led primarily to fine-tuning the navigation of SMART. Positive reviews were received from global wheelchair professionals (i.e., educators, researchers, clinicians). The Launch Version of the SMART (smart.wheelchairnetwork.org) provides a forum for sharing and accessing resources to inform the integration and enhancement of wheelchair content into university rehabilitation programs. CONCLUSIONS: As an open-source open-access online "living document," SMART has the potential to promote the integration of wheelchair service provision education into academic curricula of rehabilitation programs. Future studies will explore the ease of use and the effectiveness of the SMART.

Design and evaluation of a laboratory-based wheelchair castor testing protocol using community data.

Wheelchair castors fail frequently causing physical, social and economic consequences for wheelchair users. These failures occur in spite of established wheelchair test methods and regulations, suggesting that the existing tests may not be sufficient to screen poorly designed castors. An expert stakeholder group, convened by the International Society of Wheelchair Professionals (ISWP), noted castor failures as a high priority and recommended that a new castor testing system should be developed. In a previous study, the effect of shock exposure on castor durability was studied. The current paper extends the previous work and focuses on the development of a castor testing protocol based on shock, corrosion and abrasion exposure data collected in the community. The testing protocol was applied to 8 different castor models tested under four conditions: shock, corrosion + shock, abrasion + shock and abrasion + corrosion + shock. For each model, a total of n = 8 samples were evaluated across the four conditions. Results demonstrate that corrosion and abrasion reduced castor durability between 13% to 100% depending on the model. Importantly, the inclusion of corrosion and abrasion resulted in changes in the failure modes for 75% of the tested models and two-thirds of the altered failure modes are associated with increased risk of injury for wheelchair users. These results suggest that corrosion and abrasion present in the community reduce castor durability, thus supporting their inclusion in the castor testing protocol and potentially other wheelchair standards.

Comparing the effectiveness of a hybrid and in-person courses of wheelchair service provision knowledge: A controlled quasi-experimental study in India and Mexico.

BACKGROUND: Evidence highlights a global shortage of wheelchair service provision education and training that results in inappropriate wheelchair provision with associated health and economic consequences. Two learning methodologies, a hybrid and an in-person course, based on the World Health Organization Wheelchair Service Training Package Basic Level, currently are available to train wheelchair service providers worldwide. The effectiveness of the in-person methodology, used as the standard of practice, has never been tested. Meanwhile, the Hybrid Course, which combines online and in-person training, was developed to reduce training costs and to scale training interventions and has shown potential effectiveness in increasing basic level wheelchair service provision knowledge. The objective of this study was to compare the effectiveness of both learning methodologies based on knowledge and satisfaction among a group of wheelchair service providers in India and Mexico. METHODS: We conducted a controlled quasi-experimental study to evaluate changes in basic wheelchair knowledge and levels of satisfaction between Hybrid and In-person course learners in India and Mexico. A convenience sampling method guided by local stakeholders' input was used to recruit participants. Outcomes were assessed using self-administered online surveys, the International Society of Wheelchair Professionals Wheelchair Service Provision Basic Test (primary outcome) completed pre- and post- the learning intervention and an anonymous Satisfaction Survey (secondary outcome) completed post- intervention. Baseline characteristics were compared among groups using hypothesis tests based on their assumptions. The primary analysis was intention-to-treat. To address missing values and lost to follow-up, multiple chained imputations were conducted. The primary outcome was analyzed using linear mixed models. The secondary outcome was analyzed using a two-tailed two independent samples t-test. RESULTS: A total of 81 participants, 43 (53.1%) in the In-person group and 38 (46.9%) in the Hybrid group, participated in the study. Mean baseline knowledge scores were below the passing cutoff of the test (53 points) in both groups. Both study groups experienced statistically significant improvements in the primary outcome when comparing pre- and post-test scores (p<0.0001) with total mean scores above the passing cutoff of the test. The in-person group experienced, on average, larger effects on the primary outcome. The difference in mean change from post-test to pre-tests between In-person groups and Hybrid was 3.6 (95% Confidence Interval: 1.7;5.4), Cohen's d = 0.36, with a small effect size favoring the In-person training. With regards to satisfaction, the difference between the two interventions was 0.23±0.07 in favor of the In-person group (p = 0.0021). CONCLUSIONS: Both learning methodologies had a statistically significant effect in increasing wheelchair service knowledge with overall high levels of satisfaction. However, the In-person group reported overall larger effects when compared with the Hybrid methodology. This study provided recommendations on how organizations can improve blended learning interventions to enhance participants' learning experiences and reduce potential barriers and limitations.

Developing country-specific wheelchair service provision strategic plans for Romania and the Philippines.

Background: Achieving appropriate wheelchair provision at a national level is complex, requiring regulations, funding and policies established through governments. Understanding wheelchair provision within different countries is key. This paper describes the process used to support the development of wheelchair service strategic plans in Romania and the Philippines. It considers the influences, meaning, challenges and developments when producing strategic priorities within two different contexts. Methods: The International Society of Wheelchair Professionals (ISWP) sponsored affiliates Motivation Foundation Romania and the Philippine Society of Wheelchair Philippine Society of Wheelchair Professionals (PSWP), to conduct organizational ethnographic mixed method stakeholder centred studies, to develop robust strategic plans. An affiliate coordinator for wheelchair provision in less resourced settings supported this process. Results: Diversity between the two-affiliate sites was evident, influencing value placed within both societies towards equality and participation. Common components to address included: advocacy; wheelchair service infrastructure; capacity building; education; training and research. Research process facilitation supported by affiliate coordinator is important. Conclusion: Understanding contextual dimensions, which sharp a countries wheelchair service, is essential. Member states should take action by conducting in-country wheelchair sector analysis, to create wheelchair provision strategies for sustainable development, to meet personal posture and mobility needs, primary for daily living, as a basic human right. Implications for rehabilitation Understanding the complexity of providing appropriate wheelchairs within different countries is essential to meet the diverse needs of citizens. Conducting situational analysis of the wheelchair sector involving key stakeholders in the process is important to understand different perspectives and develop strategic priorities towards sustainable development. Producing context specific wheelchair sector reports and strategic plans strengthens the evidence base when informing governments regarding the importance of developing sustainable wheelchair provision infrastructures. The affiliate coordinator role is important to support affiliates to produce robust documentation that clearly and objectively outlines the wheelchair sector issues and plans, to provide solutions.

Detection and classification methodology for movements in the bed that supports continuous pressure injury risk assessment and repositioning compliance.

Pressure injuries are costly to the healthcare system and mostly preventable, yet incidence rates remain high. Recommendations for improved care and prevention of pressure injuries from the Joint Commission revolve around continuous monitoring of prevention protocols and prompts for the care team. The E-scale is a bed weight monitoring system with load cells placed under the legs of a bed. This study investigated the feasibility of the E-scale system for detecting and classifying movements in bed which are relevant for pressure injury risk assessment using a threshold-based detection algorithm and a K-nearest neighbor classification approach. The E-scale was able to detect and classify four types of movements (rolls, turns in place, extremity movements and assisted turns) with >94% accuracy. This analysis showed that the E-scale could be used to monitor movements in bed, which could be used to prompt the care team when interventions are needed and support research investigating the effectiveness of care plans.

The future of the provision process for mobility assistive technology: a survey of providers.

PURPOSE: The purpose of this study was to evaluate the opinions of providers of mobility assistive technologies to help inform a research agenda and set priorities. MATERIALS AND METHODS: This survey study was anonymous and gathered opinions of individuals who participate in the process to provide wheelchairs and other assistive technologies to clients. Participants were asked to rank the importance of developing various technologies and rank items against each other in terms of order of importance. Participants were also asked to respond to several open-ended questions or statements. RESULTS: A total of 161 providers from 35 states within the USA consented to participation and completed the survey. CONCLUSIONS: This survey revealed themes of advanced wheelchair design, assistive robotics and intelligent systems, human machine interfaces and smart device applications. It also outlined priorities for researchers to provide continuing education to clients and providers. These themes will be used to develop research and development priorities. Implications for Rehabilitation • Research in advanced wheelchair design is needed to facilitate travel and environmental access with wheelchairs and to develop alternative power sources for wheelchairs.• New assistive robotics and intelligent systems are needed to help wheelchairs overcome obstacles or self-adjust, assist wheelchair navigation in the community, assist caregivers and transfers, and aid ambulation.• Innovations in human machine interfaces may help advance the control of mobility devices and robots with the brain, eye movements, facial gesture recognition or other systems.• Development of new smart devices is needed for better control of the environment, monitoring activity and promoting healthy behaviours.

Implementation of the hybrid course on basic wheelchair service provision for Colombian wheelchair service providers.

INTRODUCTION: People with mobility impairments often rely on wheelchairs as their primary means of mobility. Untrained wheelchair service providers may provide inappropriate wheelchairs and services which result in negative consequences in wheelchair users' health, quality of life, safety, and social participation. This study aimed to evaluate the influence of the Spanish Hybrid Course on Basic Wheelchair Service Provision, a training based on the World Health Organization's Wheelchair Service Training Program-Basic Level, to increase knowledge in basic level wheelchair service provision among a group of wheelchair service providers from Colombia. In addition, we developed a satisfaction survey which participants completed after the training to understand levels of satisfaction with the training intervention. METHODS: A quasi-experimental study was conducted to evaluate changes in basic level wheelchair knowledge using the Wheelchair Service Provision-Basic Test. Paired sample t tests were used to assess pre-and post-training changes in basic level wheelchair knowledge. The Hybrid Satisfaction Survey was developed in collaboration with a multidisciplinary, international stakeholders' group. The survey's construct of interest was level of satisfaction determined by interaction, instructor, instruction methodology, content, and technology, using a five-point Likert scale (0 = strongly disagree to 4 = strongly agree). The survey was completed anonymously after the training intervention and analyzed using frequencies and percentages. RESULTS: Fifteen wheelchair service providers in Colombia completed the Spanish Hybrid Course. Mean post-scores were significantly higher (Mean (M) = 56.13, Standard Deviation (SD) = 7.8), than pre-assessment scores (M = 50.07, SD = 8.38, t(14) = 4.923, p = <0.0001). Participants who completed the surveys (N = 15) reported that the Spanish Hybrid Course was well received, with 98.66% of responses distributed in favorable levels (>3). CONCLUSIONS: The Spanish Hybrid Course proved to be effective in increasing basic level wheelchair knowledge with a high satisfaction level among participants. Further testing is needed to evaluate the effectiveness of this course across different individuals and countries as a potential tool to build professional capacity in basic level wheelchair provision.

Development of a Hybrid Course on Wheelchair Service Provision for clinicians in international contexts.

INTRODUCTION: Wheelchair users worldwide are at high risk of developing secondary health conditions and premature death due to inappropriate wheelchair provision by untrained providers. The International Society of Wheelchair Professionals (ISWP) has developed a Hybrid Course based on the World Health Organization's Wheelchair Service Training Package-Basic Level. The Hybrid Course leverages online modules designed for low-bandwidth internet access that reduces the in-person training exposure from five to three and a half days, making it less expensive and more convenient for both trainees and trainers. METHODS: The Hybrid Course was designed using a systematic approach guided by an international group of stakeholders. The development followed the Quality Matters Higher Educational Rubric, web design guidelines for low bandwidth, experts' opinions, and the best practices for blended course design. A quasi-experimental approach was used to evaluate the effectiveness of the Hybrid Course taken by six graduate students in Rehabilitation Sciences at the University of Pittsburgh by measuring pre- and post knowledge using the validated ISWP Wheelchair Service Provision-Basic Test. The outcome measure was assessed using a paired sample t-test between pretest and posttest scores. The quality of the Hybrid Course was evaluated by three external reviewers using the Quality Matters Higher Educational Rubric who were blind to each others' evaluation and the results of the training intervention. RESULTS: Hybrid Course participants reported significant increases in scores on the ISWP Wheelchair Service Provision-Basic Test after participating in the training, with an average increase of 10.84±5.42, p = 0.004, Cohen's d = 1.99. In addition, the Hybrid Course met the Quality Matters Standards in two out of three evaluations and reported a percentage of agreement between evaluators of 84%. CONCLUSIONS: The Hybrid Course met quality standards and proved to be effective in increasing basic level wheelchair knowledge in a group of Rehabilitation Science graduate students.

The Voice of the Consumer: A Survey of Veterans and Other Users of Assistive Technology.

Introduction: A total of 3.6 million Americans and over 250,000 veterans use wheelchairs. The need for advancements in mobility-assistive technologies is continually growing due to advances in medicine and rehabilitation that preserve and prolong the lives of people with disabilities, increases in the senior population, and increases in the number of veterans and civilians involved in conflict situations. The purpose of this study is to survey a large sample of veterans and other consumers with disabilities who use mobility-assistive technologies to identify priorities for future research and development. Materials and Methods: This survey asked participants to provide opinions on the importance of developing various mobility-assistive technologies and to rank the importance of certain technologies. Participants were also asked to provide open-ended comments and suggestions. Results: A total of 1,022 individuals, including 500 veterans, from 49 states within the USA and Puerto Rico completed the survey. The average age of respondents was 54.3 yr, and they represented both new and experienced users of mobility-assistive technologies. The largest diagnostic group was spinal cord injury (SCI) (N = 491, 48.0%). Several themes on critical areas of research emerged from the open-ended questions, which generated a total of 1,199 comments. Conclusion: This survey revealed several themes for future research and development. Advanced wheelchair design, smart device applications, human-machine interfaces, and assistive robotics and intelligent systems emerged as priorities. Survey results also demonstrated the importance for researchers to understand the effects of policy and cost on translational research and to be involved in educating both consumers and providers.

Developing product quality standards for wheelchairs used in less-resourced environments.

BACKGROUND: Premature failures of wheelchairs in less-resourced environments (LREs) may be because of shortcomings in product regulation and quality standards. The standards published by the International Organization for Standardization (ISO) specify wheelchair tests for durability, safety and performance, but their applicability to products used in the rugged conditions of LREs is unclear. Because of this, wheelchair-related guidelines published by the World Health Organization recommended developing more rigorous durability tests for wheelchairs. OBJECTIVES: This study was performed to identify the additional tests needed for LREs. METHODS: First, a literature review of the development of ISO test standards, wheelchair standards testing studies and wheelchair evaluations in LREs was performed. Second, expert advice from members of the Standards Working Group of the International Society of Wheelchair Professionals (ISWP) was compiled and reviewed. RESULTS: A total of 35 articles were included in the literature review. Participation from LREs was not observed in the ISO standards development. As per wheelchair testing study evidence, wheelchair models delivered in LREs did not meet the minimum standards requirement. Multiple part failures and repairs were observed with reviewed field evaluation studies. ISWP experts noted that several testing factors responsible for premature failures with wheelchair parts are not included in the standards and accordingly provided advice for additional test development. CONCLUSION: The study findings indicate the need to develop a wide range of tests, with specific tests for measuring corrosion resistance of the entire wheelchair, rolling resistance of castors and rear wheels, and durability of whole wheelchair and castor assemblies.

Development of a contextually appropriate, reliable and valid basic Wheelchair Service Provision Test.

PURPOSE: Currently, there is no internationally accepted way to measure the competency of wheelchair service professionals. The International Society of Wheelchair Professionals aims to develop a Wheelchair Service Provision - Basic Test as a preliminary step towards establishing a certification process. METHOD: A team of wheelchair service provision experts developed test questions and conducted alpha and beta testing in order to validate them. Low-performing test items were eliminated. A pilot test was then conducted, which focused on developing a pass score, determining language barriers and validating the test as a measure of competency. RESULTS: 90 participants completed one of three versions of the Wheelchair Service Provision - Basic Test. A pass score of 70% was established and 135 questions were accepted for the final test. Analysis of variance indicated there was a difference in scores based on language (p = 0.001), but not based on experience level. This result motivated translation in to the United Nations' official languages. CONCLUSIONS: The results indicate that the Wheelchair Service Provision - Basic Test is a valid method for measuring basic competency of wheelchair professionals. Additionally, researchers recommend a skills assessment to help to ensure only qualified wheelchair professionals receive the certificate. Implications for Rehabilitation Identify key steps in contextually appropriate test development. Describe the components of a contextually appropriate, reliable, and valid test for basic wheelchair service provision. Identify methods used for contextually appropriate test validation.
