Impact of structured wheelchair services on satisfaction and function of wheelchair users in Zimbabwe

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.

Provision of paediatric wheelchairs in low resource settings: a scoping review

PURPOSE

Inadequate wheelchair provision in children can lead to delays in growth and development, poorer health, and decreased participation. Wheelchair provision for children can be challenging, especially in low-resource settings, due to limited resources. Therefore, the purpose of the scoping review was to gain an understanding of the current state of paediatric wheelchair provision in low resource settings and identify factors, strategies, and gaps that can lead to more successful wheelchair provision.

METHODS

This scoping review used literature published after 2010, related to paediatric wheelchair provision in low resource settings. We searched online databases and grey literature and extracted data based on categories from the World Health Organisation Guidelines to wheelchair provision in low resource settings.

RESULTS

34 articles were used to identify and analyse common themes and successful strategies related to wheelchair provision for children in low resource settings. Aspects of paediatric wheelchair provision were mentioned in the literature but were rarely the focus. End-user outcomes were the least represented category in the literature.

CONCLUSION

Based on the currently available evidence the overall state of a wheelchair for children is inadequate. Improvements in design and production, personnel capacity, and service delivery systems are recommended to promote best practices. The lack of child-focussed wheelchair provision and end-user involvement in the research process urgently needs to be addressed.Implications for RehabilitationIdentify best practiceIdentify gaps in knowledgeDetermine areas of need for future research.

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.

A Goal-Directed Program for Wheelchair Use for Children and Young People with Cerebral Palsy in Uganda: An Explorative Intervention Study

In this exploratory study, we investigate whether goal-directed intervention for wheelchairs can increase the activities of daily living for children and young people with cerebral palsy (CP) when implemented in rural Uganda. Thirty-two children and young people with CP (aged 3–18 years) participated in a home-visit intervention program, which included donating wheelchairs and setting individual goals. Goal achievement, frequency of wheelchair use, condition of wheelchairs, and caregivers’ perspectives were collected by interviews at 6–10 month after the start of intervention and the after three years. Our result show that most wheelchairs were in good condition and frequently used after 6–10 month with 83% goal achievement (132/158 goals; mean 4.3 (range 0–7). The caregivers reported several advantages (e.g., the child being happier) and few disadvantages (e.g., poor design and durability). At the three-year follow-up, only eleven wheelchairs were still used by 23 available participants (seven deceased and two moved). The children achieved 60% of their goals (32/53 goals mean 2.9; range 1–5). This demonstrates that the goal-directed intervention program for wheelchairs can be successfully implemented in a low-income setting with a high rate of goal achievement and frequent wheelchair use, facilitating participation. However, maintenance services are crucial to obtain sustainable results.

Patient Satisfaction with Occupational Therapy Services for Wheeled Mobility and Seating Devices

Satisfaction of 81 patients was evaluated before and after receiving occupational therapy services. There was a statistically significant difference between patients' scores before and after receiving occupational therapy services (p < .05). Over 85% indicated a high satisfaction in relation to quality and health outcomes attributed to occupational therapy services, 44% reported barriers related to limited availability, accessibility, and knowledge of occupational therapy services, and 35% made suggestions for improvements. Patient-therapist communication and easy access to occupational therapy services can enhance occupational therapy knowledge, lead to positive patient experience and quality health outcomes, and higher patient satisfaction.

Service delivery for complex rehabilitation technology: a scoping review

PURPOSE

Complex rehabilitation technologies (CRT) support independence for individuals with disabilities by enabling mobility for function, employment, education, and independent living. CRT service delivery is evolving, with changes to funding, provider qualifications, consumer needs, and technological advances. This scoping review investigated service delivery processes for individuals with disabilities who have a mobility impairment, while specifically identifying best practices, barriers, and unique features of health delivery policies and practices.

METHODS

We used a framework described by Colquhoun et. al. for conducting scoping reviews, a six-step process that includes: 1) identifying the research question, 2) identifying studies, 3) selecting studies 4) data charting, 5) reporting results and 6) consultation. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) was also used for reporting results of the review.

RESULTS

Common categories were identified and organised into a hierarchical structure of four categories and 16 sub-categories. The primary categories included "policy", "consumer", "service delivery", and "wheeled mobility devices". The sub-categories described funding sources, consumer and professional populations, service delivery guidelines, and types of mobility devices. Analysis indicated the data were from 21 countries and 14 combinations of funding sources, and the articles were primarily descriptive studies.

CONCLUSION

This scoping review identified evidence from various countries, health systems, and stakeholder. Currently, this process does not proactively address the needs of individuals with mobility disabilities. The scoping review provides the foundation for the development of a novel policy on the provision of CRT services and devices to address these needs.Implications for RehabilitationExamination of national and international service delivery practices in diverse clinical and funding environments indicate various challenges and opportunities for improvement.CRT consumers are negatively impacted by current service delivery practices, including long wait times, lack of specialised clinical expertise, and limited consumer education opportunities.More consistent and widespread research is needed within the CRT provision industry to grow evidence-based practice related to complex rehabilitation technology and individuals with disabilities.

Wheelchair service provision education in Canadian occupational therapy programs

Occupational therapists in Canada play a central role in wheelchair service provision. Inadequate entry-to-practice professional education has been identified as a major concern in the delivery of wheelchair related services. The goal of this study was to describe the current education provided in Canadian occupational therapy programs and to map this content against the recommended WHO 8-step wheelchair service provision process. The study used a descriptive cross-sectional online survey design. Educators were recruited from accredited occupational therapy programs in Canada. Participants completed a short sociodemographic questionnaire and a survey with 97 closed- and open-ended questions regarding the wheelchair service provision education provided in their curriculum. Survey data was then mapped according to the WHO 8-step wheelchair service provision process. Twenty-nine educators from all Canadian occupational therapy programs (n = 14) were enrolled. Most participants (55.2%) were full-time faculty members that had been teaching in occupational therapy programs for an average time of 10.9 years. All programs covered at least 4 of the WHO recommended steps, but only 5 programs covered all steps. Assessment and Prescription steps were covered in every program while the Referral & Appointment, Funding & Ordering, Fitting and User Training steps were covered in most programs. The pedagogic approach, the amount of time dedicated to wheelchair-related content, and the type of evaluation used varied greatly between programs. This study is the first to provide a detailed description of wheelchair service provision education across all Canadian occupational therapy programs according to the WHO 8 steps and provides a foundation for collaborative efforts to promote best practice in entry-to-practice professional education.

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

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.

Surveying Therapists on Seating Approaches for Patients with Muscular Dystrophy in Japan

Patients with muscular dystrophy (MD) need fitted wheelchairs. This study aimed to ascertain physiotherapists and occupational therapists’ opinions about the current wheelchair seating process for patients with MD in Japan. We identified 266 academic papers published between August 2014 and July 2019 with the keywords “muscular dystrophy” and either “physiotherapy” or “occupational therapy.” We then sent survey requests to 140 physiotherapists and occupational therapists (who were among the authors of the aforementioned papers), of whom 41 agreed to partake in this study. We found that the time required for each seating was 30–60 min for three types of MD, and the most commonly reported time to trial fitting was 1–3 months. In addition, health insurance reimbursements for seating were considered part of disease-specific rehabilitation in most cases, and most therapists were more or less satisfied with the current seating procedure. Physiotherapists had the highest degree of reflection of their views (wishes) regarding seating, followed by MDs and their families. In Japan, seating has been regarded as a medical practice since 2017. In the future, we would like to investigate the seating concept for individual therapists in detail.

Pressure distribution in tilting and reclining wheelchairs with an air cushion: A pilot study

Study aim: The aim of this study was to determine the optimal angle for maximizing pressure distribution in two types of wheelchairs (tilting and reclining) while using a ROHO cushion, which offers relatively effective pressure distribution.

Material and methods: This study enrolled 28 male and female college students who understood the purpose of the study and agreed to participate. This study aimed to determine the optimal angle for tilting and reclining wheelchairs when using a ROHO cushion at angles of 10°, 20°, and 30° with tilted wheelchairs and 90°, 110°, and 130° with reclining wheelchairs.

Results: The analysis showed that an improved pressure distribution when a tilting wheelchair was used versus a reclining one. A reclining position of ≥110° and a tilt angle of ≥20° led to significant pressure-reducing effects.

Conclusion: The results of this study will help wheelchair users or their guardians to select the optimal wheelchair angle when changing their posture to prevent bedsores. Although no slippage was observed in our study, it is important to remember the proper back position to prevent unnecessary slippage.

"Unknown world of wheelchairs" A mixed methods study exploring experiences of wheelchair and seating assistive technology provision for people with spinal cord injury in an Irish context

AIM

This study explores people living with spinal cord injury (SCI) experiences and perspectives of wheelchair and seating assistive technology service provision within an Irish context. There are few studies that examine the process of wheelchair and seating provision and the connection between satisfaction, performance, and participation.

METHOD

This mixed methods study explores participant experiences in two parts. Part one presents a thematic analysis of eight in-depth semi-structured interviews with wheelchair service users living with SCI. Part two presents the results content and frequency analysis of an on-line survey of wheelchair service user's experience and satisfaction with wheelchair and seating service provision from respondents with SCI (n = 117) taken from a larger national survey from respondents with various diagnoses (n = 273).

RESULTS

Findings from the interviews and survey revealed the meaning of wheelchair and seating assistive technology provision as essential to life following SCI. Barriers within the provision system such as wait times and funding were found to impede people's rights and freedom from initial assessment through to follow up, maintenance and repair.

CONCLUSIONS

The current implementation of wheelchair and seating assistive technology provision as described in this paper impacts the ability of individuals living with an SCI to participate as equal members of society. A review of wheelchair provision is essential to optimize access to services for appropriate wheelchairs.IMPLICATIONS FOR REHABILITATIONAs a basic human right, appropriate wheelchair and seating assistive technology provision facilitates people's optimal independence, health and well-being, social engagement, and participation in everyday life.The development of adequate wheelchair services should be a priority area for individuals with SCI who use wheelchair and seating assistive technology.National wheelchair and seating assistive technology provision policies in alignment with internationally developed best practice guidelines to provide equal access to services which include assessment, delivery, training, maintenance, and follow-up are essential.

Looking under the veil: Challenges faced by people with disabilities in cross-border entrepreneurship

BACKGROUND

Cross-border entrepreneurship is one source of livelihood that is transforming people's lives, especially those with limited resources and educational qualifications and those in need of supplementary earnings to complement meagre formal earnings. However, despite strides made to make this avenue worthwhile, this Zimbabwean study shows that hidden hindrances still persist from procedural and structural barriers from road entry point management systems. To people with disabilities (PWDs), the impact of these hidden barriers is severe to the extent of obstructing their optimum progression into cross-border entrepreneurship.

OBJECTIVES

This article sought to interrogate some veiled challenges in border management systems affecting PWDs' quest to venture into cross-border entrepreneurship. This angle has, to this end, been timidly addressed as most organisations and legislation have concentrated on making things work for the majority of the populace.

METHOD

Qualitative phenomenological method in which researchers' lived experiences, review of literature, ideas and opinions is complemented by secondary survey data from a road entry point management system study in the Zimbabwean setting.

RESULTS

Cross-border entrepreneurship has potential to transform people's lives: 1) road and border management systems' procedural and structural complications present hidden challenges impeding PWDs' entry and optimum participation in cross border entrepreneurship, 2) people with disabilities are not automatically dependents; in fact, most have dependents looking up to the, 30 social construction of disability persists and must be curbed and 4) there is a need to institute a 'stakeholders triad approach'.

CONCLUSION

The existing road entry points' management systems are not informed by considerations from PWDs, hence the existence of hidden challenges. Cross-border entrepreneurship can open significant livelihood avenues to PWDs. A stakeholders 'triad-approach', proposed herein, can solve some of the policy discrepancies as it recommends utilising inputs from PWDs, research and policy-makers.

Wheelchair and seating assistive technology provision: a gateway to freedom

Aim: The meaning of wheelchair and seating assistive technology and the impact inappropriate provision has on people's lives from a service user's perspective within an Irish context is highlighted. There is a dearth in evidence examining the process of wheelchair and seating provision and the interconnectedness between satisfaction, performance and participation from an equality and human rights perspective. The purpose if the study is to investigate wheelchair service users' perspectives of wheelchair and seating provision in Ireland.Method: This is a mixed-methods study with an exploratory sequential design that includes two phases. During phase one, wheelchair service users were invited to take part in qualitative in-depth semi-structured interviews, which were thematically analysed and formed part of a larger ethnographic study involving multiple stakeholders in sustainable wheelchair and seating provision strategy development. In phase two, an online Survey Monkey questionnaire was distributed to obtain a wider overview of wheelchair service provision from a wheelchair service users perspective. Data obtained from the closed questions and content analysis for open comments was analysed descriptively for this phase.Results: Eight wheelchair service users agreed to participate in the interviews and 273 responded to the online survey. Thematic analysis and questionnaire frequency and content analysis revealed the vital meaning of wheelchair and seating assistive technology provision. However, bottlenecks within the system affect daily living, with qualitative data highlighting the obstruction to experiences of independent living from initial appointment to wheelchair breakdowns during daily life.Conclusion: Appropriate wheelchair and seating assistive technology provision is a basic human right, supported by the essential and embodied nature of the wheelchair as demonstrated through the wheelchair service users' perspective throughout this study. These findings highlight the impact of ad-hoc services on individual freedoms and how the overall pace of the system affects a person's ability to organise their time as an equal member of the community across the lifespan. A national review of wheelchair and seating assistive technology provision services is called for, giving consideration to access to services, assessment and delivery, follow up and management, education and training.IMPLICATIONS FOR REHABILITATIONWheelchair and seating assistive technology provision as a basic human right is misunderstood.Appropriate wheelchair and seating assistive technology provision should be provided to meet this primary need as a pre-requisite for survival.Every aspect of the wheelchair and seating provision process impacts on occupational performance, equality of opportunity and community mobility. Wheelchair and seating assistive technology professionals and providers have a responsibility to review their practice and service provision systems.

The inter-rater reliability of the Wheelchair Interface Questionnaire

PURPOSE

Wheelchair outcomes measures are useful to support evidence-based practice in wheelchair provision, especially in low- and middle-income countries (LMIC). The Wheelchair Interface Questionnaire (WIQ) was developed to provide a professional perspective on the quality of the interface between a wheelchair and its user. Studies conducted during the development of the WIQ indicated it has face validity and content validity. The objective of this field study was to conduct a subsequent investigation of the inter-rater reliability of the WIQ at a school for children with disabilities in Kenya.

MATERIALS AND METHODS

Eight practitioners with wheelchair experience from disparate cultural backgrounds participated in the study. They evaluated eight wheelchairs and the interface with their users. The interclass correlation coefficient (ICC) of the mean rating for the eight-item dataset was computed using SPSS.

RESULTS

The ICC was found to be 0.911, indicating that the WIQ possesses inter-rater reliability. Common comment topics indicated that the qualitative data yielded by the WIQ is meaningful. Informal timing indicated that the WIQ is a brief measure.

CONCLUSION

The WIQ is a reliable tool that can meet the need for a professional assessment of the wheelchair-user interface. The reliability of this questionnaire is important because the tool can be used to evaluate the interface between a wheelchair user and their wheelchair, strengthening evidence-based practice in wheelchair provision.Implications for RehabilitationBased on the score of a specific wheelchair interface, a rehabilitation professional could recommend more assessment, seating modification, or wheelchair replacement in order to maximize rehabilitation benefit for a clientThe WIQ could provide evidence-based information to support the need for wheelchair repair or replacement to funders.In large-scale studies involving many of the same wheelchair type in the same setting, the WIQ could be used to identify problems with the interface between that wheelchair type and its intended user population so that manufacturers can make responsive design changes.The WIQ could be used in a clinical setting over time to identify the most common wheelchair interface issues for that setting.

Integration of wheelchair service provision education: current situation, facilitators and barriers for academic rehabilitation programs worldwide

Purpose: An estimated 75 million people with disabilities need wheelchairs globally, of whom 5-15% have one. Access to an appropriate wheelchair requires rehabilitation professionals trained to provide wheelchair service. One aim of the International Society of Wheelchair Professionals (ISWP) is to promote and facilitate the integration of wheelchair service provision education into academic rehabilitation programs worldwide. To inform the development of integration strategies, the purpose of this study was to develop an in-depth global portrait of the wheelchair service provision education offered in academic rehabilitation programs, the process of its integration and the associated facilitators and barriers.Method: Semi-structured qualitative interviews were conducted with a purposive sample of 14 representatives from academic rehabilitation programs (i.e., occupational therapy, physical therapy, and prosthetics and orthotics) in 11 countries, including low, middle and upper resourced settings.Findings: Thematic data analyses identified three overarching themes. The first theme, "impact of context", portrays factors related to local population needs, governance and supply chain of equipment and service delivery. The second theme, "current and planned wheelchair education", describes the content, pedagogic approach, student evaluation and feedback process. The third theme, "integration process", details five states of this process.Conclusions: This study describes in-depth the wheelchair service provision education across academic rehabilitation programs and resource settings, illustrating the context-dependent nature of its integration. This understanding may assist the global community of educators in preparing future rehabilitation professionals to better serve wheelchair users. This work has informed the development of ISWP's Seating and Mobility Academic Resource Toolkit (http://smart.wheelchairnetwork.org/).Implications for RehabilitationThe Dynamics of Context-Dependent Integration of Wheelchair Service Provision Education in Curricula model, depicting the findings of this study, may help to inform key stakeholders (i.e., academic institutions, health care providers and policy makers) about potential barriers and facilitators to the implementation of adequate wheelchair service provision education in the curricula of academic rehabilitation program.Study findings may lead to creative strategies, such as the expansion of ISWP's Seating and Mobility Academic Resource Toolkit (SMART; http://smart.wheelchairnetwork.org/), that may enable academic rehabilitation programs to be a part of the solution to strengthening rehabilitation systems worldwide, through appropriately trained rehabilitation professionals in wheelchair service provision.

Development of the Wheelchair Interface Questionnaire and initial face and content validity

Background

Because resources are limited in low- and middle-income countries (LMIC), the development of outcome measures is of interest. Wheelchair outcome measures are useful to support evidence-based practice in wheelchair provision.

Objectives

The Wheelchair Interface Questionnaire (WIQ) is being developed to provide a professional perspective on the quality of the interface between a wheelchair and its user. This article discusses the development of the WIQ and its face and content validity.

Method

During field studies in Kenya, we sought to include professional report data on the wheelchair–user interface that could be analysed to inform design changes. None of the existing measures was focused on the interface between users and their wheelchairs. The WIQ was developed to meet this need. To investigate face and content validity, 24 experienced wheelchair professionals participated in a study that included two rounds of an online survey and a focus group in Kenya.

Results

Responses were categorised by topic and the WIQ was modified following each iteration. Participants affirmed the usefulness of a brief professional report measure to provide a snapshot of the user–wheelchair interface. Participants emphasised the importance of brevity, wide applicability and provision of specific feedback for wheelchair modification or design changes. The focus group agreed that the final version provided useful data and was applicable to virtually all wheelchair users in LMIC.

Conclusion

These preliminary studies indicate initial face and content validity of the WIQ as a method for providing a professional perspective on the interface between a user and his or her wheelchair.

Keywords

Outcome measure; wheelchair assessment; user–wheelchair interface; wheelchair appropriateness; professional report.

Development and evaluation of a wheelchair service provision training of trainers programme

Background

In many countries, availability of basic training and continued professional development programmes in wheelchair services is limited. Therefore, many health professionals lack access to formal training opportunities and new approaches to improve wheelchair service provision. To address this need, the World Health Organization (WHO) developed the WHO Wheelchair Service Training of Trainers Programme (WSTPt), aiming to increase the number of trainers who are well prepared to deliver the WHO Wheelchair Service Training Packages. Despite these efforts, there was no recognised method to prepare trainers to facilitate these training programmes in a standardised manner.

Objectives

To understand if the WSTPt is an effective mechanism to train aspiring wheelchair service provision trainers.

Method

An action research study was conducted using a mixed-methods approach to data collection and analysis to integrate feedback from questionnaires and focus groups from three WHO WSTPt pilots.

Results

Trainees were satisfied with the WHO WSTPt and the iterative process appears to have helped to improve each subsequent pilot and the final training package.

Conclusion

The WHO WSTPt is an effective mechanism to train wheelchair service provision trainers. This programme has potential to increase the number of trainees and may increase the number of qualified service 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.

A longitudinal study assessing the maintenance condition of cadres of four types of wheelchairs provided in low-resource areas

Wheelchair breakdowns increase the risk of injury and limit the mobility of wheelchair users. In the endeavour to meet the enormous global need for wheelchairs, manufacturers of wheelchairs for low-resource settings face a cost-benefit tension between affordability and durability. Field studies are needed to provide feedback on durability. Four manufacturers provided cadres of wheelchairs to the organization providing rehabilitation to students at a boarding school for children with disabilities in a low-resource area. The Wheelchair Components Questionnaire for Condition was used to evaluate wheelchair maintenance condition at several time intervals after fitting. Because the maintenance regime was not identical for the four wheelchair types, wheelchair types were not compared. Analysis of variance indicated differences in condition across time and between wheelchair components. Tukey's simultaneous comparison of means indicated that across the entire group, brakes, seats, casters and foot rests received lower ratings than frame. Preliminary data after each iteration of this study were provided to manufactures and resulted in responsive design changes. Implications for Rehabilitation Longitudinal studies with the Wheelchair Components Questionnaire for Condition (WCQc) have enabled manufacturers to make responsive design improvements. Additional studies could be done with other wheelchair types to result in responsive positive design changes for those wheelchairs as well. The WCQc can be used in studies on wheelchair condition even when records of repair history are not reliably available, a situation which is not uncommon in low-resource areas. Data sets collected at an individual clinic uses the WCQc could focus attention on wheelchair components needing regular repair. With that data in mind, the maintenance regime could be modified to respond and in so doing improve wheelchair condition and reduce loss of mobility or risk of injury. Organizations involved in funding wheelchairs for a particular location could use data from longitudinal studies done with the WCQc at that location to inform purchasing decisions.
