Historical technology transfer activities and productivity of NIDLRR grantees.

This paper analyzes the technology-related outputs from The National Institute of Disability, Independent Living, and Rehabilitation Research (NIDILRR). We seek to answer the questions: What are the types and frequency of assistive technology (AT) technology transfer (ATTT) outputs from NIDILRR grants? How does NIDILRR's ATTT generation compare to other granting organizations? What types of ATTT outputs occur, how, and what is the relative productivity of the most frequently funded universities and small businesses performing with funding by NIDILRR grants? An online search was conducted for indications of ATTT from grants funded from 1983-2021 through publicly available databases, the National Rehabilitation Information Center (NARIC), and the internet. This data was then categorized across relevant output types and analyzed. NIDILRR funded 662 organizations and 951 different investigators from 1983 to 2021. The NIDILRR-funded portfolio includes 6,996 papers, 438 informational websites, 163 patents, 120 software products, and 29 hardware products. Compared to the National Institutes of Health (NIH), NIDILRR produced slightly more products per dollar. Our results highlight the substantial portfolio of technology-related outputs generated with NIDILRR funding and demonstrate how productivity measures can be calculated to guide future funding strategies.

Use of Assistive Technology for Persons with Psychosocial Disability: Systematic Review.

BACKGROUND: Assistive technology (AT) refers to assistive products (AP) and associated systems and services that are relevant for function, independence, well-being, and quality of life for individuals with disabilities. There is a high unmet need for AT for persons with disabilities and this is worse for persons with cognitive and mental or psychosocial disabilities (PDs). Further, information and knowledge on AT for PDs is limited. OBJECTIVE: The aim of this review was to explore the pattern of AT use among persons with PDs and its associated socioeconomic and health benefits. METHODS: The review was reported according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses), and we conducted systematic searches in the 4 databases: PubMed, Embase.com, APA PsycInfo (Ebsco), and Web of Science (Core Collection) with the following index terms: "Assistive Technology," "Self-Help Devices," "Quality of Life," "Activities of Daily Living," "Mental Disorders." We included only AT individuals with PDs can independently use without reliance on a provider. Identified papers were exported to EndNote (Clarivate) and we undertook a narrative synthesis of the included studies. RESULTS: In total, 5 studies were included in the review which reported use of different AT for schizophrenia, bipolar disorder, depression and anxiety disorders. The APs described in the included studies are Palm tungsten T3 handheld computer, MOBUS, personal digital assistant, automated pill cap, weighted chain blankets, and smartphone function. All the AT products identified in the studies were found to be easily usable by individuals with PDs. The APs reported in the included studies have broad impact and influence on social function, productivity, and treatment or management. The studies were heterogeneous and were all conducted in high-income countries. CONCLUSIONS: Our study contributes to and strengthens existing evidence on the relevance of AT for PDs and its potential to support socioeconomic participation and health. Although AT has the potential to improve function and participation for individuals with PDs; this review highlights that research on the subject is limited. Further research and health policy changes are needed to improve research and AT service provision for individuals with PDs especially in low-income settings.

Effects of the WHO 8-step wheelchair-service-delivery process on wheelchair users in El Salvador: a cohort study.

PURPOSE: To test the hypotheses that, after the delivery of manual wheelchairs following the WHO 8-step service-delivery process, wheelchair-related health and quality of life, wheelchair skills, wheelchair use, and poverty probability would improve; and that the number of wheelchair repairs required, adverse events, caregiver burden, and the level of assistance provided would decrease. METHODS: This was a longitudinal, prospective within-subject study including 247 manual wheelchair users, and 119 caregivers, in El Salvador who received a wheelchair following the WHO 8-step process as well as maintenance reminders. Outcome measurements were performed via structured questionnaires and dataloggers at the initial assessment, at wheelchair delivery, and at 3- and 6-month follow-up. RESULTS: Significant improvements in wheelchair-related health indicators (all with p < 0.004) and quality of life (p = 0.001), and a significant reduction in national and "extreme" poverty probability (p = 0.004 and p = 0.012) were observed by six months. Wheelchair use significantly decreased (p = 0.011 and p = 0.035) and wheelchair skills increased (p = 0.009). Caregiver burden did not change (p = 0.226) but the number of activities of daily living (ADLs) that required no assistance significantly increased (p = 0.001) by three months and those who required complete assistance decreased (p = 0.001). No changes were observed in wheelchair repairs (p = 0.967) and breakdowns over time with new wheelchairs. CONCLUSIONS: Wheelchair service delivery using the WHO 8-step process on manual wheelchair users in El Salvador has positive effects on health and quality of life, wheelchair skills, caregiver assistance levels, and poverty. Further research is needed to determine the relative contributions of the intervention components.Implications for RehabilitationProviding manual wheelchairs using the 8-step process of the WHO has benefits on health and quality of life, wheelchair skills, caregiver assistance levels, and poverty.The WHO 8-steps service delivery process for manual wheelchairs can be used in less-resourced settings.

Evaluation of providers' assistive technology service delivery practices in Pakistan.

PURPOSE: Globally, one in three individuals needs at least one assistive product. The primary objective of this study was to conduct a survey of Pakistani rehabilitation service providers to determine what proportion provide assistive technology and if their characteristics (including geographical region, education, and experience) are associated with adherence to the service delivery process. The secondary objective was to determine if individuals that provide assistive technology adhere to a standard assistive technology service delivery process. The tertiary objective was to determine if the providers that adhered to a standard delivery process had characteristics that differed from the rest of the service providers. MATERIALS AND METHODS: An online survey composed of multiple-choice questions was distributed to physiotherapists, community-based healthcare workers, and related rehabilitation professions through a convenience sampling method. SPSS Statistics was used to develop correlation matrices to determine Pearson's coefficient of number of steps, education level, experience level and continuing education received. RESULTS: There were 71 respondents from 4 Pakistani provinces. 53.5% of respondents stated they provide assistive technology. There was participation in most steps of the service delivery process. There is weak correlation between number of steps and education level, number of steps and experience level, and number of steps and continuing education received. CONCLUSIONS: While the majority of respondents provide assistive technology, a significant proportion (46.5%) don't. This may suggest there is a need for additional advocacy and awareness raising of the benefits of and how to access assistive technology in Pakistan.

Implications for RehabilitationPakistan implemented a Rapid Assistive Technology Assessment and determined that only 22% of the population that needs an assistive device has had their needs met.From a relatively small sample, this study investigated if there is a presence of assistive technology service delivery in Pakistan and whether traditional education, experience, or continuing education promotes participation in the assistive technology service delivery process.This study found a presence of assistive technology service delivery in Pakistan, but found weak correlations between participation in the service delivery process with traditional education, experience, and continuing education.These findings suggest that there is room for additional advocacy and awareness training on assistive technology in Pakistan.

A novel approach to directly measuring wheel and caster rolling resistance accurately predicts user-wheelchair system-level rolling resistance.

Introduction: Clinical practice guidelines for preservation of upper extremity recommend minimizing wheelchair propulsion forces. Our ability to make quantitative recommendations about the effects of wheelchair configuration changes is limited by system-level tests to measure rolling resistance (RR). We developed a method that directly measures caster and propulsion wheel RR at a component-level. The study purpose is to assess accuracy and consistency of component-level estimates of system-level RR. Methods: The RR of N = 144 simulated unique wheelchair-user systems were estimated using our novel component-level method and compared to system-level RR measured by treadmill drag tests, representing combinations of caster types/diameters, rear wheel types/diameters, loads, and front-rear load distributions. Accuracy was assessed by Bland-Altman limits of agreement (LOA) and consistency by intraclass correlation (ICC). Results: Overall ICC was 0.94, 95% CI [0.91-0.95]. Component-level estimates were systematically lower than system-level (-1.1 N), with LOA +/-1.3 N. RR force differences between methods were constant over the range of test conditions. Conclusion: Component-level estimates of wheelchair-user system RR are accurate and consistent when compared to a system-level test method, evidenced by small absolute LOA and high ICC. Combined with a prior study on precision, this study helps to establish validity for this RR test method.

An exploratory analysis of global trends in wheelchair service provision knowledge across different demographic variables: 2017-2020.

To explore global trends in manual wheelchair service provision knowledge across geographic, professional, and socioeconomic domains. A secondary analysis of a dataset from the International Society of Wheelchair Professionals' Wheelchair Service Provision Basic Knowledge Test was conducted. 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. International Society of Wheelchair Professionals' Wheelchair Service Provision Basic Knowledge Test. 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). 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.

Design refinement and evaluation of a mobile manual standing wheelchair.

PURPOSE: There are no manually propelled wheelchairs on the market that are mobile in both seated and standing positions. In response to this product gap, our group formerly designed a mobile manual standing wheelchair (MMSW) and gathered stakeholder feedback. The purpose of this study was to refine the MMSW based on feedback, including weight and width reduction, and evaluate its performance. MATERIALS AND METHODS: The MMSW was subjected to ANSI/RESNA stability testing, and three male participants completed a subset of the wheelchair skills test, including a 100-m roll test in the MMSW (seated and standing) and in their ultralight wheelchair. RESULTS: The MMSW met ANSI/RESNA stability safety standards. During the 100-m roll test, participants reached speeds with the MMSW in both the standing and sitting postures similar or greater than those typical of moving in the home environment (1.11 m/s seated; 0.79 m/s standing). Mobility speeds in the MMSW in the standing position were about three times faster than average walking speeds in exoskeletons (0.26 m/s exoskeletons). With the addition of chain drive bracing to the MMSW, one user was able to reach speeds in the standing position similar to average neurotypical walking speeds indicating the possibility for wheelchair users to be able to move in pace with family and friends. CONCLUSION: All participants expressed interest in the MMSW to facilitate improved quality of life. Further work is needed to test the utility of the MMSW in home and community settings, and its potential effects on standing time and health outcomes.Implications for rehabilitationManual standing wheelchairs with standing mobility may increase functional utility and length of standing time for manual wheelchair usersIncreased standing time may lead to several health benefits for manual wheelchair users.

A descriptive analysis of wheelchair repair registry data.

Wheeled mobility and seating (WMS) devices allow users to achieve greater mobility independence. Previous studies determined that 53% of wheelchair users required one or more repairs over a 6-month period; however, there are a limited number of studies that have evaluated types of repairs. The purpose of this study was to describe the types of manual wheelchair, power wheelchair, and scooter repairs within the Wheelchair Repair Registry (WRR) and examine the association between WMS devices and the frequency of repairs. A dataset of 4,645 devices distributed in the United States was collected from equipment suppliers who performed and logged community-based wheelchair repair services. The results demonstrated common repairs found across devices were within the wheels/tires/forks and batteries/cables categories. Device type was the most significant predictor of variance in the number of repairs. Customizable manual wheelchairs, tilt-in-space, Groups 2 & 3 power wheelchairs, and scooters were associated with higher number of repairs compared to non-customizable manual wheelchairs, pediatric, heavy-duty manual wheelchairs, and Group 4 power wheelchairs. The higher failure rate found in specific devices may be associated with a population of more active users, environment/conditions where equipment is used, time spent in equipment, additional features on device, or lower durability.

A high prevalence of manual wheelchair rear-wheel misalignment could be leading to increased risk of repetitive strain injuries.

PURPOSE: To determine the prevalence and severity of manual wheelchair rear wheel misalignment in community-dwelling manual wheelchair users and estimate the associated increases in rolling resistance (RR) and risk of repetitive strain injuries (RSIs). MATERIALS AND METHODS: Data were collected in an outpatient rehabilitation clinic, a university research laboratory, and at adaptive sporting events in the United States. Two hundred active, self-propelling manual wheelchair users were recruited. Angular misalignment (referred to as toe angle) while the wheelchair was loaded with the user, and the difference between the maximum and minimum toe angle (referred to as slop) with the wheelchair unloaded. RESULTS: Average results for toe angle and slop (movement in the rear wheels) were 0.92 and 0.61 degrees, respectively. Using a lab-based testing method, we quantified the impact of increased RR forces due to misalignment in increased RR forces. Our results indicate that the average toe angle while under load and slop, without loading, measured in the community increase required propulsion force by 3.0 N. Combined toe angle and slop (i.e., the worst-case scenario) added increased propulsion force by 3.9 N. CONCLUSIONS: We found that rear-wheel misalignment was prevalent and severe enough that it may increase the risk for RSIs and decrease participation. To mitigate this issue, future work should focus on reducing misalignment through improved maintenance interventions and increased manufacturing quality through more stringent standards.Implications for RehabilitationThe work reveals a previously unknown and significant contributor to RR that could have health implications for users who self-propel.Maintenance and repairs should be adjusted to help reduce the impact of misalignment.Our results suggests that WC designers should take additional care to designs wheels and frames to minimize misalignment.Service providers setting up wheelchairs should take additional care to make sure the wheels are aligned.Users should monitor misalignment and prioritize maintaining or having their chair repaired when misalignment occurs.

Using the lens of assistive technology to develop a technology translation readiness assessment tool (TTRAT)™ to evaluate market readiness.

PURPOSE: Assistive Technologies encompass a wide array of products, services, healthcare standards, and the systems that support them. Product/market fit is necessary for a technology to be transferred successfully. Current tools lack variables that are key to technology transfer, and current trainings do not have a validated tool to assess the effectiveness of a training, increasing innovators' readiness for technology transfer. The goal was to develop a tool to evaluate the readiness of a technology by incorporating other models and focusing beyond just commercialization. MATERIALS AND METHODS: The development involved five stages: 1. Review of current tools used in technology transfer in academic, government, and industry settings; 2. Development of the draft version of the tool with internal review; 3. Alpha version review and refinement, 4. Content validation of the tool's beta version; 5. Assessment of the readiness tool for reliability and preparedness for wide-use dissemination. RESULTS: The tool was revised and validated to 6 subscales and 25 items. The assistive technology subscale was removed from the final version to eliminate repetitive questions and taking into consideration that the tool could be used across technologies. CONCLUSIONS: We developed a flexible assessment tool that looked beyond just commercial success and considered the problem being solved, implications on or input from stakeholders, and sustainability of a technology. The resulting product, the Technology Translation Readiness Assessment Tool (TTRAT)TM, has the potential to be used to evaluate a broad range of technologies and assess the success of training programs.IMPLICATIONS FOR REHABILIATIONQuality of life can be substantially impacted when an assistive technology does not meet the needs of an end-user. Thus, effective Assistive Technology Tech Transfer (ATTT) is needed.The use of the TTRAT may help to inform NIDILRR and other funding agencies that invest in rehabilitation technology development on the overall readiness of a technology, but also the impact of the funding on technology readiness.The TTRAT may help to educate novice rehabilitation technology innovators on appropriate considerations for not only technology readiness, but also general translation best practices like assembling a diverse team with appropriate skillsets, understanding of the market and its size, and sustainability strategies.

Barriers and facilitators to technology transfer of NIDILRR grantees.

PURPOSE: The objectives of this mixed-methods study were to gather survey and interview data about the barriers and facilitators from grantees funded by the National Institute on Disability, Independent Living, and Rehabilitation Research (NIDILRR) and to extract themes that could inform program changes that would increase technology translation (TT) success in assistive technology (AT). MATERIALS AND METHODS: We developed a TT Barriers and Facilitators survey consisting of Likert scale and multiple-choice questions about barriers and facilitators to TT. With survey respondents who were willing, we conducting a semi-structured interview and asked pointed questions to expand upon survey response rankings and perceived barriers and facilitators. The questions were framed to explore the grantee's personal experience with ATTT and what helped and hindered their individualised processes. RESULTS: Across survey and interview respondents, the three most common themes when exploring the barriers and facilitators of TT were funding, incentives, and collaboration. CONCLUSIONS: Results indicate that there is a need for increased collaboration and access to additional resources such as funding for pilot grants, support to assess technology marketability, help to navigate regulatory and legal aspects, and assistance in establishing goals to help grantees successfully transfer assistive technologies to consumers. IMPLICATIONS FOR REHABILITATIONA large amount of research and development into assistive technology does not lead to tech transfer which means that these technologies are not getting to the people that need them.Educating tech transfer offices at universities about how to transfer AT would improve outcomes greatly.Creating a community of practice where grantees can find academic or industry partners would also increase the likelihood of tech transfer.Some tools to catalyse these improvements are: mentoring, access to consultants, podcasts, and online training.

Wheelchair service provision content in professional rehabilitation organisations' standards documents and contemporary initiatives: a rapid review.

PURPOSE: We sought to identify opportunities, challenges, contemporary initiatives and strategies for preparing entry-level practitioners who are competent at the basic level of wheelchair service provision across four key international professional rehabilitation organisations as revealed by their educational standards, relevant guidelines and policy statements, and other publicly available information. METHOD: A rapid review was conducted in 2021 from the International Society of Physical and Rehabilitation Medicine (ISPRM), the International Society for Prosthetics and Orthotics (ISPO), World Physiotherapy, and the World Federation of Occupational Therapists (WFOT). Additional grey-literature and grey-data searches were conducted to identify contemporary initiatives that may support competency development in wheelchair service provision. RESULTS: A total of 17 standards, guidelines, and policy statement documents were selected for detailed review. Each of the four organisations published at least one document containing language relating to wheelchair service provision. Twelve contemporary initiatives relating to wheelchair service provision were identified from the grey literature across the four organisations. Six additional initiatives were identified from the organisations' social media accounts. Themes emerged in the areas of contemporary content, opportunities, and challenges. CONCLUSION: Global standardisation could help harmonise professional societies' approach to training wheelchair service providers.IMPLICATIONS FOR REHABILITATIONThere is a need to provide more descriptive content on wheelchair service provision in education and service standards and related documents to influence what is taught in professional rehabilitation programs that are accredited or approved by professional rehabilitation organisations.The organisations' networks are vast and may also help to promote additional continuing education in this area.

Development, validation and feasibility study of a remote basic skills assessment for wheelchair service providers.

AIM: The purpose of this study was to develop, validate and conduct a feasibility study of three remote basic skills assessment modalities for wheelchair service providers (WSP) including an online case study quiz (m1), an in-person skills assessment (m2) and a video conference skills assessment (m3). METHODS: We conducted a literature review; developed and validated 3 basic skills assessments; and conducted a feasibility study of each modality. RESULTS: The literature review revealed that a validated remote basic skills assessment for WSP that reflects all World Health Organization (WHO) 8 wheelchair service provision steps did not exist. We recruited a total of 12 participants for the feasibility study. Two participants dropped out of the study prior to completing a second testing modality. Related to test performance, the results show that our first hypothesis was rejected because only m1 mean score was comparable to the International Society of Wheelchair Professionals (ISWP) Basic Knowledge Test (SD = 0.44). This is in contrast with the Wilcoxon signed-rank test results that show a statistically significant difference between these two modalities. We are therefore not confident that the knowledge test was an appropriate comparison to m1 skills assessment. Hypothesis two was not rejected. The feasibility results reveal 86% success. CONCLUSION: M1, 2 and 3 have the potential to serve as remote basic skills assessments. However, according to both test performance and feasibility criteria, we believe that m2 has the highest potential to be included in certification processes for basic wheelchair service providers, like the one offered by ISWP.IMPLICATIONS FOR REHABILITATIONA universal remote basic skills assessment that can be accessed across the globe, especially in remote locations where a skilled and experienced provider is not available, is needed.Such test can be an asset to training or professional organisations like ISWP as a way to test WSP competency or to warrant certification.WSP clinical knowledge and skills are essential for the prescription of an appropriate wheelchair to avoid physical harm, abandonment of the device and unnecessary expenses.Properly prescribed wheelchairs allow people with impaired mobility to gain increased ability to perform ADLs, participate in communities, and reduce secondary medical complications such as upper limb repetitive strain injuries, pain, and/or pressure sores.

Evaluation of rolling resistance in manual wheelchair wheels and casters using drum-based testing.

PURPOSE: Rolling resistance is a drag force that increases the required propulsion force of manual wheelchair users (MWU) and increases the risk of upper extremity pain and injury. MATERIALS AND METHODS: To understand the influence of different design, environmental, and setup factors on rolling resistance (RR), a series of tests were performed on a range of wheels and casters using a drum-based equipment with the capability to measure RR forces. Independent factors were varied including load, camber, toe, speed, tire pressure, and surface, using ranges anticipated in the community. Combined factor testing of these factors was also completed to evaluate of RR changes due interactions of multiple factors. RESULTS: A default reference trial was used to verify repeatability throughout the 924 rear wheel trials and 255 caster trials. Toe angle and tire pressure were found to have large and exponential relationships to RR. Tire/caster type and surfaces are significant influencers but have no specific relationship to RR. Load had a direct linear relationship to RR whereas camber and speed had a relatively small impact on RR. Pneumatic tires had lower rolling resistance compared to airless inserts, solid mag wheels and knobby tires. Combined factor testing revealed a linear additive effect of individual factors. Statistical analysis revealed that tire/caster type is a covariate to all of the results and statistical differences (p < 0.01) were found for toe, tire/caster type, tire pressure, surfaces and load. CONCLUSIONS: Factors act in a cumulative manner to impact RR and need to be monitored in device design, development, issuance, and maintenance.Implications for RehabilitationFirst comprehensive study of MWC RR showing the effects of individual and combined factors.Highlights the direct importance of tire and caster selection.

Effectiveness of Group Wheelchair Maintenance Training for People with Spinal Cord Injury: A Randomized Controlled Trial.

OBJECTIVE: To assess the effectiveness of group wheelchair maintenance training and investigate participant characteristics associated with responsiveness to training. DESIGN: Randomized controlled trial with an immediate group and a waitlist control group (WLCG) who received the intervention after a 6-month delay. SETTING: Four Spinal Cord Injury Model Systems Centers. PARTICIPANTS: Manual (MWC; n=80) and power wheelchair (PWC; n=67) users with spinal cord injury (N=147). INTERVENTIONS: Two 90-minute structured wheelchair maintenance training program classes with 12-20 people per class and separate classes for MWC and PWC users. Each class included in-person hands-on demonstrations and practice of wheelchair maintenance. MAIN OUTCOME MEASURES: Separate analysis was completed for MWC and PWC users using the Wheelchair Maintenance Training Questionnaire (WMT-Q) capacity (ability to complete), performance (frequency of completion) and knowledge at baseline, 1 month, 6 months, 6 months pretraining (WLCG only), and 1 year (immediate only). RESULTS: After the intervention, participants in both the immediate and WLCG improved in maintenance capacity (MWC and PWC, P<.001) and performance (MWC and PWC, P<.001) with training. Only PWC users improved knowledge of wheelchair maintenance (P<.001). For both WLCGs (MWC and PWC), there was no difference between the 6-month pretraining time point and baseline. MWC users who responded to training had lower WMT-Q scores for all domains, whereas this was only the case for knowledge for PWC users. CONCLUSIONS: Group wheelchair skills training is effective at improving capacity to complete maintenance and performance of maintenance activities for MWC and PWC users, even in a cohort of experienced wheelchair users. For MWC users, improvements were tied to lower WMT-Q scores at baseline, whereas PWC users improved in capacity and performance independent of baseline score. Delivering this training in a structured group format has a lower cost, which might improve adoption into clinical practice.

Rolling resistance of casters increases significantly after two years of simulated use.

INTRODUCTION: Manual wheelchair propulsion is associated with upper limb pain and injury, and clinical guidelines recommend minimizing propulsive force to lower health risks. One of the strategies to reduce propulsive force is by minimizing rolling resistance (RR). Product testing studies suggest that RR of casters is affected by wear and tear which could have implications on the health risk of wheelchair users. The study will investigate the relationship between caster RR and environmental exposure using standard testing protocols. METHODS: RR of ten casters representing a range of diameters for different models of wheelchairs were measured before and after environmental exposure that includes corrosion, shock and abrasion simulating two years of community use. RESULTS: Four casters exhibited failures during durability testing, one catastrophically. Increases to RR after corrosion, shock and abrasion exposure were statistically significant using mixed-effects modeling, and four casters had increased RR greater than 20%. CONCLUSIONS: Many of the casters evaluated exhibited increased RR forces and failure after environmental exposure. Improved caster design and use of corrosion resistant materials may reduce these failures. In addition, modification of the provision process could include replacement casters to reduce failures and avoid breakdowns that leave manual wheelchair users stranded or injured.

Exploratory investigation of the outcomes of wheelchair provision through two service models in Indonesia.

The World Health Organization (WHO) estimates that only 17-37% of the approximately 77 million people who need a wheelchair have access to one. Many organizations are trying to address this need through varying service delivery approaches. For instance, some adhere to WHO's recommended 8-steps service approach while others provide wheelchairs with little to no service. There is limited and sometimes conflicting evidence of the impact of the WHO's recommendations on the outcomes of wheelchair provision. To help build this evidence, we \explored outcomes of two groups of users who received their wheelchairs through two service models over time. The 8-Steps group (n = 118) received a wheelchair selected from a range of models from service providers trained using the WHO process, and the standard of care (SOC) group (n = 24) received hospital-style wheelchairs and without clinical service. Interviews were conducted at baseline and at follow-up 3 to 6 months after provision, to collect data about wheelchair usage, satisfaction, skills, maintenance and repairs, and life satisfaction. Across-group statistical comparisons were not appropriate due to significant differences between groups. In general, participants used their wheelchairs every day but reported very low mobility levels (<500 meters for the 8-steps group, and <100 meters for the SOC group.) The 8-steps group used their wheelchair for either between 1-3 hours per day, or more than 8 hours per day. The SOC used it between 1 and 3 hours per day. Overall, wheelchair usage and wheelchair skills decreased over the 3- to 6-month data collection timeline. Wheelchair breakdowns were common in both groups emphasizing the need for maintenance, occurring more frequently in the 8-Steps (28.8%) compared to the SOC group (8%), and emphasizing the need for maintenance services. No significant differences were found when comparing device satisfaction across wheelchairs types. Our results emphasize the need for routine maintenance to address frequent wheelchair breakdowns. Our results also demonstrate a large disparity in several outcome variables across groups which motivates future studies where across-group comparisons are possible.

Understanding the Global Challenges to Accessing Appropriate Wheelchairs: Position Paper.

Introduction: Appropriate wheelchairs are often essential for the health and wellbeing of people with mobility impairments to enhance fundamental freedoms and equal opportunity. To date, provision has mainly focused on just delivering the wheelchair instead of following an evidence-based wheelchair service delivery process. In addition, many governments have not committed to a national wheelchair provision policy. Approach: To prepare this position paper, a systemic development model, founded on the sustainable human security paradigm, was employed to explore the global challenges to accessing appropriate wheelchairs. Positions: I: Consideration of key perspectives of wheelchair provision across the life course is essential to meet the needs to children, adults, older people and their families; II: Comprehensive wheelchair service delivery processes and a competent workforce are essential to ensure appropriate wheelchair service provision; III: Evaluations on wheelchair product quality development, performance and procurement standards are key as wheelchair product quality is generally poor; IV: Understanding the economic landscape when providing wheelchairs is critical. Wheelchair funding systems vary across jurisdictions; V: Establishing wheelchair provision policy is a key priority, as specific policy is limited globally. Conclusion: The vision is to take positive action to develop appropriate and sustainable wheelchair service provision systems globally, for me, for you, for us.

Development of a Wheelchair Repair Registry.

OBJECTIVE: To describe the development of a wheelchair repair registry from large datasets to attain an understanding of wheelchair failures and service repairs. DESIGN: Guidelines for registry development were applied and anchored around Labor-Tracker, a web-based information management system for wheelchair suppliers to manage and track wheelchair repairs. The registry was designed using online analytical processing, allowing for rapid data queries from multiple dimensions that enable complex data analysis and discovery. SETTING: The Wheelchair Repair Registry (WRR) was developed through an industry and academic collaboration whereby repair data were collected in the field, entered into the Labor-Tracker system, deidentified, and then transferred to the registry and made available for analyses. PARTICIPANTS: Wheelchair supplier service technicians reported data from repair services provided to individuals who use power wheelchairs, manual wheelchairs, and scooters. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Wheelchair failure and repair data, including variables related to scheduling, equipment information (eg, manufacturer, model, serial number, purchase date), labor, parts, and reasons for repairs. RESULTS: The WRR was developed to analyze wheelchair repairs and failures from the Labor-Tracker system. Currently, the registry has more than 60,000 repairs conducted on more than 5000 wheelchair devices from 25 manufacturers. The devices include 60% power wheelchairs, 35% manual wheelchairs, and 5% scooters. CONCLUSIONS: The WWR creates opportunities to apply large-data analytical methodologies that will serve to inform quality standards, practice, equipment selection, preventative maintenance routines, product design, and policy.

Scoping review of the rolling resistance testing methods and factors that impact manual wheelchairs.

INTRODUCTION: Rolling resistance (RR) is a drag force acting on manual wheelchairs that is associated with increased propulsion force and is linked to secondary disabling conditions of the upper limbs. A scoping review was conducted to understand how RR of manual wheelchairs has been measured and to identify limitations of those test methods and the factors tested. METHODS: A total of 42 papers were identified and reviewed, and test methods were categorized based on the measurement style of RR, testing level, and if multiple parameters could be tested. Additionally, 34 articles were reviewed for what factors were tested. RESULTS: Seven different testing methods categories were identified: drag test, treadmill, motor draw, deceleration, physiological expenditure, ergometer/dynamometer, and robotic test rig. Relevant articles were categorized into testing factor categories: camber, toe, tire type, tire pressure, caster type, mass, mass distribution, and type of surface. CONCLUSIONS: The variety of testing methods suggests the need for a standardized method that can be used for wheelchair wheel design and selection to reduce RR. It is important to use adjustments, such as a forward rear axle position to mitigate RR as well as using high-pressure pneumatic tires that are properly inflated.
