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.

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.

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.

Comparison of High-Strength Aluminum Ultralight Wheelchairs Using ANSI/RESNA Testing Standards.

Background: The use of ultralight manual wheelchairs has been shown to benefit wheelchair users when compared to other types. New aluminum alloy frame materials coming to the market have not been independently evaluated for durability and cost benefit. Methods: Three 70XX aluminum ultralight wheelchair models were tested and compared based on dimensions, stability, and durability using the ANSI/RESNA standards. The results were also compared to previous manual wheelchair studies. Results: This study found that there were no significant cost benefit or durability differences between the wheelchairs tested and previous aluminum or titanium ultralight rigid models. Additionally, 5 of the 9 wheelchairs tested failed to meet the minimum ANSI/RESNA requirements for durability. Conclusion: These results are similar to results from previous rigid ultralight wheelchair studies and indicate that the quality of wheelchairs of this type has not improved and better requirements are necessary for wheelchairs marketed in the United States.

Consumer Feedback to Steer the Future of Assistive Technology Research and Development: A Pilot Study.

Objective: The overall objective of this project was to identify consumers' opinions of their needs and wants related to assistive technology (AT) in a systematic and quantitative manner via a questionnaire that can be used to validate existing and establish new research priorities. Methods: This pilot study describes questionnaire development, online implementation, and revisions considered to the questionnaire in preparation for conducting a nationwide survey. Data from a sample (N = 112) are presented. The pilot study was critical to refine the questions and ensure that meaningful information was being collected. Results: It was identified that revisions were warranted to provide more structure and allow for consumers to prioritize AT research efforts. Conclusion: The questionnaire results, although positively in favor of many of the technologies presented, are inconclusive to identify generalizable research priorities, thus expansion to a nationwide population is warranted.

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

BACKGROUND: For people who have a mobility impairment, access to an appropriate wheelchair is an important step towards social inclusion and participation. The World Health Organization Guidelines for the Provision of Manual Wheelchairs in Less Resourced Settings emphasize the eight critical steps for appropriate wheelchair services, which include: referral, assessment, prescription, funding and ordering, product preparation,fitting and adjusting, user training, and follow-up and maintenance/repairs. The purpose of this study was to investigate how the provision of wheelchairs according to the World Health Organization's service provision process by United Cerebral Palsy Wheels for Humanity in Indonesia affects wheelchair recipients compared to wait-listed controls. METHODS: This study used a convenience sample (N = 344) of Children, Children with proxies, Adults, and Adults with proxies who were on a waiting list to receive a wheelchair as well as those who received one. Interviews were conducted at baseline and a 6 month follow-up to collect the following data: Demographics and wheelchair use questions, the World Health Organization Quality of Life-BREF, Functional Mobility Assessment, Craig Handicap Assessment Recording Technique Short Form. The Wheelchair Assessment Checklist and Wheelchair Skills Test Questionnaire were administered at follow up only. RESULTS: 167 participants were on the waiting list and 142 received a wheelchair. Physical health domain in the World Health Organization Quality of Life-BREF improved significantly for women who received a wheelchair (p = 0.044) and environmental health improved significantly for women and men who received a wheelchair as compared to those on the waiting list (p < 0.017). Satisfaction with the mobility device improved significantly for Adults with proxies and Children with proxies as compared to the waiting list (p < 0.022). Only 11 % of Adults who received a wheelchair reported being able to perform a "wheelie". The condition of Roughrider wheelchairs was significantly better than the condition of kids wheelchairs for Children with proxies as measured by the Wheelchair Assessment Checklist (p = 0.019). CONCLUSIONS: Wheelchair provision according to World Health Organization's 8-Steps in a less-resourced setting has a range of positive outcomes including increased satisfaction with the mobility device and better quality of life. Wheelchair provision service could be improved by providing more hours of wheelchair skills training. There is a need for outcome measures that are validated across cultures and languages.

Current state of mobility technology provision in less-resourced countries.

This article reviews mobility technology in less-resourced countries, with reference to people with disabilities in several locations, and describes technology provision to date. It also discusses a recent collaborative study between a United States University and an Indian spinal injuries hospital of Indian wheelchair users' community participation, satisfaction, and wheelchair skills. The data suggest that individuals who received technology from the hospital's assistive technology department experienced increased community participation and improved wheelchair skills. This evidence may have already enabled the hospital to improve Indian governmental policies toward people with disabilities, and it is hoped that future research will benefit other people similarly.

Longitudinal assessment of vibrations during manual and power wheelchair driving over select sidewalk surfaces.

Wheelchair users rely on their wheelchairs for mobility for extended periods of time every day. According to the International Standards Organization 2631-1 standard on human vibration, individuals in a seated position when exposed to whole-body vibrations (WBV) are at risk of injury. This study evaluated vibration exposure during manual and power wheelchair driving over nine sidewalk surfaces and differences in vibration exposure over 3 years. Ten nondisabled subjects were asked to drive a manual wheelchair at 1 m/s and a power wheelchair at 1 m/s and 2 m/s over nine sidewalk surfaces while WBV were measured at the seat and footrest of the wheelchair. At 1 m/s, significant differences existed between surfaces and years at both the seat and the footrest for the manual and power wheelchair users. At 2 m/s, significant differences existed between surfaces and years at the seat and the footrest for power wheelchair users. Our results show that both manual and power wheelchair users may be at risk for secondary injuries from WBV when traveling over certain surfaces.

Evaluation of the safety and durability of low-cost nonprogrammable electric powered wheelchairs.

OBJECTIVE: To evaluate whether a selection of low-cost, nonprogrammable electric-powered wheelchairs (EPWs) meets the American National Standards Institute (ANSI)/Rehabilitation Engineering and Assistive Technology Society of North America (RESNA) Wheelchair Standards requirements. DESIGN: Objective comparison tests of various aspects of power wheelchair design and performance of 4 EPW types. SPECIMENS: Three of each of the following EPWs: Pride Mobility Jet 10 (Pride), Invacare Pronto M50 (Invacare), Electric Mobility Rascal 250PC (Electric Mobility), and the Golden Technologies Alanté GP-201-F (Golden). SETTING: Rehabilitation engineering research center. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Static tipping angle; dynamic tipping score; braking distance; energy consumption; climatic conditioning; power and control systems integrity and safety; and static, impact, and fatigue life (equivalent cycles). RESULTS: Static tipping angle and dynamic tipping score were significantly different across manufacturers for each tipping direction (range, 6.6 degrees-35.6 degrees). Braking distances were significantly different across manufacturers (range, 7.4-117.3 cm). Significant differences among groups were found with analysis of variance (ANOVA). Energy consumption results show that all EPWs can travel over 17 km before the battery is expected to be exhausted under idealized conditions (range, 18.2-32.0 km). Significant differences among groups were found with ANOVA. All EPWs passed the climatic conditioning tests. Several adverse responses were found during the power and control systems testing, including motors smoking during the stalling condition (Electric Mobility), charger safety issues (Electric Mobility, Invacare), and controller failures (Golden). All EPWs passed static and impact testing; 9 of 12 failed fatigue testing (3 Invacare, 3 Golden, 1 Electric Mobility, 2 Pride). Equivalent cycles did not differ statistically across manufacturers (range, 9759-824,628 cycles). CONCLUSIONS: Large variability in the results, especially with respect to static tipping, power and control system failures, and fatigue life suggest design improvements must be made to make these low-cost, nonprogrammable EPWs safe and reliable for the consumer. Based on our results, these EPWs do not, in general, meet the ANSI/RESNA Wheelchair Standards requirements.
