Comparison of carbon fibre and aluminium materials in the construction of ultralight wheelchairs.

Carbon fibre-reinforced polymers have been used in the sporting goods industry for decades, and wheelchairs have incorporated the material since the late 1980s. There is no independently collected data available on carbon fibre-reinforced polymer wheelchairs' performance on the ANSI/RESNA testing standards, however. This study evaluated three full carbon fibre wheelchair specimens to determine their performance versus similar wheelchairs. Testing determined that while the frames survived more testing cycles than any other wheelchair, the casters and rear tires failed similarly to other devices. Overall, due to the purchase cost, the cost benefit of the tested wheelchair model was similar to aluminium wheelchairs.Implications for rehabilitationCarbon fibre wheelchair construction is a viable alternative to aluminium, titanium, or steel construction, and decreasing costs will continue to improve the benefits of carbon fibre over these modelsCarbon fibre wheelchair found to be more durable than aluminium models, but are also much more expensive. The additional cost may be justified for some users that need the increased durability, howeverIncreased durability will reduce the number of repairs and warranty claims, potentially reducing the burden on a wheelchair user, and also improving their ability to travel and participate in their communityThe low weight of carbon fibre wheelchairs may increase the mobility of some users by allowing them to transfer more easily into and out of vehicles and manoeuvre throughout the environment.

A low cost solar powered vehicle - a boon for physically challenged persons.

This paper presents a low cost solar powered vehicle for physically challenged persons. Generally, the persons with physical disabilities restrict their movement within a house or building due to their dependence on other people for their outdoor work. The disabled people use their limbs to drive the wheelchairs which physically stress them. There are electrical wheelchairs which are operated by hands, by mouth or any other functioning body part. The high cost and its limitation for outdoor environment restrict its usage for rich people and hospitals. This often makes the poor disabled person to be unemployed and depend on others for their daily life. In this regard, developing a low cost self-driven electric wheel chair can improve the life of the person. This paper presents a low cost vehicle for physically challenged people that can be used as a mobile shop to sell products at any place independently. The self-driven vehicle motivates the persons to become an entrepreneur. A cost effective and user friendly prototype has been developed for the benefit the poor disabled people and the cost analysis is presented. The purpose of developing the vehicle is satisfied as they no longer depend on others for their living. Implications for rehabilitation The movement of physically challenged persons is often restricted within a building due to their dependence on other people for their outdoor work. The high cost of the assist vehicles and the difficulty encountered in using the vehicles in outdoor environment decreases their standard of living. The developed low cost vehicle can be used by physically challenged people as a mobile shop to sell products at any place independently. The self-driven vehicle motivates the physically challenged persons to become an entrepreneur.

Low-cost low-tech obstacle pushing/gliding wheelchair accessory.

Purpose: Some wheelchair users continue to struggle in maneuvering a wheelchair and navigating through manual doors. Several smart wheelchairs and robotic manipulators were developed to minimize such challenges facing disabled people. Disappointingly, a majority of these high-tech solutions are restricted to laboratories and are not extensively available as commercial products. Previously, a low-tech wheelchair accessory (arc-shaped with many wheels) for pushing doors was modelled and simulated. This work demonstrates the fabrication and testing of the first-generation prototype of the accessory.Materials and methods: The accessory has side portions with a straight arrangement of wheels and a front portion with a straight-arc-straight arrangement of wheels. The accessory was fabricated using conventional manufacturing, off-the-shelf components, and 3D printed ABS fasteners. Stress analysis simulations were done for the fasteners that attach the front accessory to the wheelchair frame. The proof-of-concept of the prototype installed onto a powered wheelchair was tested with a door and an obstacle, each with ∼50 N resistance force.Results: Prototype tests demonstrate the ability of the accessory along with the mechanical robustness of the 3D printed fasteners to push open doors allowing easy navigation through doors and to push/glide against obstacles. The accessory is foldable and detachable.Conclusion: The low-cost of the accessory makes it affordable to many users intending to improve their quality of life. The current study provides an engineering perspective of the accessory, and a clinical perspective is crucial. Other potential applications of the wheelchair accessory include use with scooters, walkers and stretchers.Implications for rehabilitationLow-cost, low-tech accessory is foldable and detachable.Accessory is effective for pushing doors and pushing/gliding against obstacles.Protective nature of the front accessory could prove highly beneficial to some wheelchair users.

National evaluation of policies governing funding for wheelchairs and scooters in Canada: Évaluation nationale des politiques régissant le financement des fauteuils roulants, des triporteurs et des quadriporteurs au Canada.

BACKGROUND: Wheelchairs, scooters, and related equipment are essential for the well-being of individuals with limited mobility and impact participation, health, and quality of life. PURPOSE: Our objective was to identify and evaluate policies governing equipment funding for Canadian adults. We reviewed funding legislation and program documentation for adult Canadians (≥18 years of age) covered by their provincial, territorial, or federal health care plan. Documents were obtained online or through administrative staff. Policy evaluation was guided by the Disability Policy Lens from the Canadian Disability Policy Alliance. KEY ISSUES: Coverage ranges from full funding for all individuals within the jurisdiction to programs limited by strict eligibility criteria. Each jurisdiction defines "disability" or "basic/essential need" differently, contributing to further funding disparities. IMPLICATIONS: Funding policies differ substantially across Canada, resulting in unequal access to equipment dependent on province or territory. We identified eligibility, funding, definitions of mobility, repair and replacement, and prescriber requirement benchmarks that represent policy targets for improved access.

A Project Course Sequence in Innovation and Commercialization of Medical Devices.

There exists a need for educational processes in which students gain experience with design and commercialization of medical devices. This manuscript describes the implementation of, and assessment results from, the first year offering of a project course sequence in Master of Engineering (MEng) in Design and Commercialization at our institution. The three-semester course sequence focused on developing and applying hands-on skills that contribute to product development to address medical device needs found within our university hospital and local community. The first semester integrated computer-aided drawing (CAD) as preparation for manufacturing of device-related components (hand machining, computer numeric control (CNC), three-dimensional (3D) printing, and plastics molding), followed by an introduction to microcontrollers (MCUs) and printed circuit boards (PCBs) for associated electronics and control systems. In the second semester, the students applied these skills on a unified project, working together to construct and test multiple weighing scales for wheelchair users. In the final semester, the students applied industrial design concepts to four distinct device designs, including user and context reassessment, human factors (functional and aesthetic) design refinement, and advanced visualization for commercialization. The assessment results are described, along with lessons learned and plans for enhancement of the course sequence.

Cost-effectiveness of powered mobility devices for elderly people with disability.

PURPOSE: The aim of this study was to analyse the cost-effectiveness of prescribing powered mobility devices (PMDs) to elderly users. METHODS: Forty-five persons participated in the pre- and post-intervention study with a follow-up at four months. All participants were prescribed a scooter model and were offered individual support to get started using the PMD. In the analysis, the use of the PMD was compared to the situation prior to its use. The cost-utility analysis takes a societal perspective and considers costs, savings and quality of life (QoL) using answers to the EQ-5D questionnaire. RESULTS: Costs for the first year with the PMD were 1395 USD and then 592 USD per subsequent year. There was a significant decrease in transportation costs and in relatives' time use, but the increase in QoL of 0.041 was not significant. Costs per gained quality adjusted life year (QALY) were 12 400-14 700 USD/QALY if the value of time saved not was considered and 600-2900 USD/QALY when an hour was valued at 3.6 USD. CONCLUSION: Prescription of PMDs to elderly users might be cost-effective. However, there are shortcomings in measuring QALY gains from the use of a PMD, and it is unclear how time savings among relatives should be valued. Implications for Rehabilitation Prescription of powered mobility devices for the elderly with disability seems to be cost effective and should be a standard intervention. In economic evaluations of powered mobility devices and other assistive devices, the commonly used analyses methods are not always appropriate and therefore need to be adjusted.

Assistive technology in resource-limited environments: a scoping review.

PURPOSE: It is estimated that only 5-15% of people in low and middle income countries (LMICs) who need assistive technologies (AT) have access to them. This scoping review was conducted to provide a comprehensive picture of the current evidence base on AT within LMICs and other resource limited environments. METHOD: The scoping review involved locating evidence, extracting data, and summarizing characteristics of all included research publications. RESULTS: Of the 252 publications included, over 80% focused on types of AT that address mobility (45.2%) and vision (35.5%) needs, with AT types of spectacles and prosthetics comprising over 50% of all publications. Evidence on AT that addresses hearing, communication, and cognition is the most underrepresented within the existing evidence base. The vast majority of study designs are observational (63%). CONCLUSIONS: Evidence on AT in resource-limited environments is limited in quantity and quality, and not evenly distributed across types of AT. To advance this field, we recommend using appropriate evidence review approaches that allow for heterogeneous study designs, and developing a common language by creating a typology of AT research focus areas. Funders and researchers must commit much greater resources to the AT field to ameliorate the paucity of evidence available. Implications for Rehabilitation An increase in the quality and quantity of research is required in resource limited environments, where 80% of the global population of people with disabilities reside. Improved and increased evidence is needed to identify and understand needs, inform policy and practice, and assess progress made in increasing access to and availability of appropriate AT. Over 80% of the existing research publications on assistive technologies in resource limited environments address mobility and vision. More research is needed on AT that address hearing, communication and cognition. The use of a common language would facilitate the advancement of the global AT research field. Specifically there is a need for researchers to use a common definition of AT (i.e., ISO 9999) and typology of AT research focus areas.

Design and validation of a low cost, high-capacity weighing device for wheelchair users and bariatrics.

Accessible high-capacity weighing scales are scarce in healthcare facilities, in part due to high device cost and weight. This shortage impairs weight monitoring and health maintenance for people with disabilities and/or morbid obesity. We conducted this study to design and validate a lighter, lower cost, high-capacity accessible weighing device. A prototype featuring 360 kg (800 lbs) of weight capacity, a wheelchair-accessible ramp, and wireless data transmission was fabricated. Forty-five participants (20 standing, 20 manual wheelchair users, and five power wheelchair users) were weighed using the prototype and a calibrated scale. Participants were surveyed to assess perception of each weighing device and the weighing procedure. Weight measurements between devices demonstrated a strong linear correlation (R2 = 0.997) with absolute differences of 1.4 ± 2.0% (mean±SD). Participant preference ratings showed no difference between devices. The prototype weighed 11 kg (38%) less than the next lightest high-capacity commercial device found by author survey. The prototype's estimated commercial price range, $500-$600, is approximately half the price of the least expensive commercial device found by author survey. Such low cost weighing devices may improve access to weighing instrumentation, which may in turn help eliminate current health disparities. Future work is needed to determine the feasibility of market transition.

A Cost-Effective Virtual Environment for Simulating and Training Powered Wheelchairs Manoeuvres.

Control of a powered wheelchair is often not intuitive, making training of new users a challenging and sometimes hazardous task. Collisions, due to a lack of experience can result in injury for the user and other individuals. By conducting training activities in virtual reality (VR), we can potentially improve driving skills whilst avoiding the risks inherent to the real world. However, until recently VR technology has been expensive and limited the commercial feasibility of a general training solution. We describe Wheelchair-Rift, a cost effective prototype simulator that makes use of the Oculus Rift head mounted display and the Leap Motion hand tracking device. It has been assessed for face validity by a panel of experts from a local Posture and Mobility Service. Initial results augur well for our cost-effective training solution.

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.

Do tilt-in-space wheelchairs increase occupational engagement: a critical literature review.

PURPOSE: A wheelchair can enhance the quality of life of an individual with limited mobility, poor trunk control and stability, by enabling activity and participation and so occupational engagement. High specification wheelchairs which can tilt-in-space enable the position of users to be altered to suit activity and context. Despite tilt-in-space wheelchairs being expensive little is known about their therapeutic value. METHODS: A critical literature review of the evidence was undertaken to evaluate whether the use of tilt-in-space increases occupational engagement. A wide ranging search strategy identified 170 articles which were screened using inclusion criteria. The eligible literature (n = 6) was analysed thematically using open coding. RESULTS: The majority of the participants used tilt-in-space but the data was too heterogeneous to combine. Measures of occupational engagement were not used so the therapeutic value could not be assessed. CONCLUSION: There is a lack of high quality evidence about the therapeutic benefits of tilt-in-space wheelchairs. Given the expense associated with providing these wheelchairs, and the increase in their provision, research is needed to justify provision of high specification wheelchairs to meet the occupational needs of users within the limited resources of health and social care. Implications for Rehabilitation Tilt-in-space wheelchairs. Wheelchairs are an important and essential assistive device for promoting independence and function. Suggests there are benefits for tilt-in-space wheelchairs. Identifies the need for additional large scale research.

Cost-effectiveness of powered wheelchairs: findings of a study.

This study surveyed a sample of 79 wheelchair users who had obtained powered wheelchairs from the National Health Service in an Italian Region in the period 2008-2013. The wheelchair prescriptions had been done on the basis of an assessment protocol agreed with the Local Health Authority. Follow-up interviews were carried out at the users' homes, in order to collect information about the wheelchair use and its effectiveness, usefulness and economic impact. The instruments used in the interviews included an introductory questionnaire (describing the wheelchair use), the QUEST (measuring the user's satisfaction), the PIADS (measuring the psychosocial impact, in terms of perceived changes in ability, adaptability and self-esteem), the FABS/M (detecting environmental facilitators and barriers) and the SCAI (estimating the economic impact). Overall, positive outcomes were detected for most users, especially in relation to their satisfaction and the psychosocial impact. A number of barriers were identified in various settings (at home, in public places, in natural spaces, in public transportation) that sometimes restrict the user mobility and thus may claim for corrective actions. Several environmental factors acting as facilitators were also identified. In relation to the economic impact, the provision of a powered wheelchair generated remarkable savings in social costs for most of the users, on average about 36.000 Euros per person on a projected 5-years span. This estimate results from the comparison between the social cost of the intervention (sum of the costs of all material and human resources involved in the provision and usage of the wheelchair) and the cost of non-intervention (the presumed social cost incurred in case no powered wheelchair had been provided and the user had to carry on with just a manual wheelchair). The study was also an opportunity to develop and try out a follow-up method that proved applicable within service delivery practice.

Users' perspectives on the provision of assistive technologies in Bangladesh: awareness, providers, costs and barriers.

PURPOSE: The purpose of this work was to contribute to a better understanding of challenges and solutions to equitable provision of assistive technologies in resource limited environments by (i) describing sources of awareness, types of providers and costs of assistive technologies; (ii) describing common reasons for not possessing assistive technologies; and (iii) comparing these sources, providers, costs and reasons among younger and older men and women living in urban and rural settings. METHODS: Descriptive and analytic statistics were used to analyze cross-sectional data from a total sample of 581 hearing aid users, wheelchair users, individuals with hearing impairments not using hearing aids and individuals with ambulatory impairments not using wheelchairs living in eight districts of Bangladesh. RESULTS: Major sources of awareness, types of providers and costs paid varied between users of different types of assistive technology. Lack of affordability was the main reason for not possessing assistive technology. Outcome differences were found between younger and older groups, men and women, and literate and illiterate respondents, while no differences related to place of living were identified. CONCLUSIONS: Age, gender, type of impairment and socioeconomic status need to be considered when planning and implementing equitable provision of assistive technologies. Implications for Rehabilitation Provision of assistive technologies needs to be made affordable as lack of affordability was the major reason for not possessing such technologies. To ensure equitable provision of assistive technology, services ought to consider age, gender, impairment and socioeconomic status of their target groups. This includes offering a range of products of different sizes provided by culturally appropriate personnel at affordable cost, which to many may be at no or reduced cost. To cater to the assistive technology needs among the most vulnerable groups, assistive technology providers may learn from CBR strategies, such as, awareness raising and service delivery at community level, the use of local resources, collaboration and coordination, and the consideration of cultural factors.

Wheelchair interventions, services and provision for disabled children: a mixed-method systematic review and conceptual framework.

BACKGROUND: Wheelchairs for disabled children (≤ 18 years) can provide health, developmental and social benefits. World Health Organisation and United Kingdom Government reports demonstrate the need for improved access to wheelchairs both locally and internationally. The use of health economics within this field is lacking. Provision of wheelchairs based on cost-effectiveness evidence is not currently possible. We conducted the first systematic review in this field to incorporate evidence of effectiveness, service user perspectives, policy intentions and cost-effectiveness in order to develop a conceptual framework to inform future research and service development. METHODS: We used an adapted EPPI-Centre mixed-method systematic review design with narrative summary, thematic and narrative synthesis. 11 databases were searched. Studies were appraised for quality using one of seven appropriate tools. A conceptual framework was developed from synthesised evidence. RESULTS: 22 studies and 14 policies/guidelines were included. Powered wheelchairs appear to offer benefits in reduced need for caregiver assistance; improved communicative, personal-social and cognitive development; and improved mobility function and independent movement. From 14 months of age children can learn some degree of powered wheelchair driving competence. However, effectiveness evidence was limited and low quality. Children and parents placed emphasis on improving social skill and independence. Participation in wider society and development of meaningful relationships were key desired outcomes. Policy intentions and aspirations are in line with the perspectives of children and parents, although translation of policy recommendations into practice is lacking. CONCLUSIONS: There is a distinct lack of high quality effectiveness and economic evidence in this field. Social and health needs should be seen as equally important when assessing the mobility needs of disabled children. Disabled children and parents placed highest priority on independence and psychosocial outcomes of wheelchair interventions. Translation of policy and guidelines into practice is lacking and more effective implementation strategies are required to improve services and outcomes. Future research should focus on outcome measure development, developing economic evaluation tools and incorporating these into high quality studies to address known research gaps. The novel conceptual framework maps current gaps in evidence and outlines areas for development.

Person factors and work environments of workers who use mobility devices.

BACKGROUND: Nearly 25% of people with mobility impairments and limitations who are of working age are employed, yet few studies have examined their perspectives on their jobs or work environments required to complete job tasks. OBJECTIVE: The purpose of this study was to describe the factors that contribute to successful employment for those who use mobility devices. PARTICIPANTS: A convenience sample of 132 workers who use power wheelchairs, manual wheelchairs, canes, crutches or walkers. METHOD: Participants completed an online version of the Mobility Device User Work Survey (MWS). A multivariate analysis and a two-step multiple linear regression analysis were used. RESULTS: Study participants had few secondary health conditions that influenced their work. Employee satisfactoriness to their employers was high. Accessibility of worksites was high. Assistive technologies were inexpensive, and personal assistance was used infrequently and usually was unpaid. Co-worker communications were very positive. Flexible work rules and supportive managers were highly valued. Job satisfaction positively correlated with accessibility, work tasks, co-worker communication and work support. CONCLUSION: The description of work environments of successfully employed mobility device users can provide some useful guidance to employers, vocational rehabilitation (VR) counselors and unemployed mobility device users to balance employee abilities and preferences with the needs of employers.

Disparities in wheelchair procurement by payer among people with spinal cord injury.

OBJECTIVE: To identify insurance provider-related disparities in the receipt of lightweight, customizable manual wheelchairs or power wheelchairs with programmable controls among community-dwelling people with spinal cord injury (SCI). SETTING: Six Spinal Cord Injury Model System centers. DESIGN: A multicenter cross-sectional study. PARTICIPANTS: A total of 359 individuals at least 16 years of age or older and 1 year after SCI who use a manual or power wheelchair as their primary means of mobility. The subjects were stratified by payer, and payers were grouped according to reimbursement characteristics as follows: Medicaid/Department of Vocational Rehabilitation (DVR), private/prepaid, Medicare, Worker's Compensation (WC)/Veterans Affairs (VA), and self pay. METHODS: Demographic, wheelchair, and payer data were collected by medical record review and face-to-face interview. RESULTS: There were 125 participants in the Medicaid/DVR group, 120 in the private/prepaid group, 55 in the Medicare group, 30 in the WC/VA group, and 29 in the self-pay group. For manual wheelchair users, the likelihood of having a lightweight, customizable wheelchair was 97.5% for private/prepaid, 96.3% for Medicaid/DVR, 94.1% for WC/VA, 87.5% for Medicare, and 82.6% for self pay. For power wheelchair users, those with WC/VA (100%) were most likely to receive a customizable power wheelchair with programmable controls, followed by private/prepaid (95.1%), Medicaid/DVR (86.0 %), Medicare (83.9%), and self pay (50.0%). CONCLUSIONS: The only payer group for which all beneficiaries received wheelchairs that met standard of care were power wheelchairs provided by WC/VA. Fewer than 90% of people whose manual wheelchair was paid for by Medicare and self pay, and whose power wheelchair was paid for by Medicaid/DVR, Medicare, and self pay did not meet standard of care. Although these findings need to be correlated with long-term risks, such as overuse injuries, breakdowns, and participation, this study demonstrates that disparities in wheelchair procurement by insurance provider persist.

Powered wheelchairs and scooters for outdoor mobility: a pilot study on costs and benefits.

PURPOSE: This study evaluates the effect of electric powered wheelchairs/scooters (PWC/S) on occupational performance, social participation, health and life satisfaction. In addition, this study estimates the costs and benefits of PWC/S and describes users' experiences with the delivery process. METHODS: This prospective study has a before-and-after design. Postal questionnaires were sent to 24 first-time PWC/S users before delivery of the PWC/S and 4 months after delivery. The participants used their PWC/S for outdoor mobility. RESULTS: PWC/S improved the users' daily lives, their ability to engage in mobility-related activities and their social participation. For a majority of the users, estimated independence, feelings of safety and self-esteem increased although overall health and life satisfaction were not significantly affected. All users thought that the therapist had considered their needs during the providing process. Most participants (73%) were satisfied with their device at follow-up. For the 12 users who reported no change in health status between measures, the mean societal savings based on calculated costs for assistance was €6227 per person per year. CONCLUSIONS: PWC/S seems to improve occupational performance, social participation and life satisfaction for users. Moreover, these improvements seem to have an economic advantage for both users and society. IMPLICATIONS FOR REHABILITATION: The use of a PWC/S has been shown to positively affect a person's independence in daily activities which in turn increases the sense of self-esteem and security. Facilitating mobility is cost-effective both from a societal as well as from anindividual perspective and should be a key intervention in rehabilitation.

The impact of a low cost wheelchair on the quality of life of the disabled in the developing world.

BACKGROUND: People with disabilities in the developing world do not have equal and adequate access to education, employment, or medical care. Their physical or mental condition, compounded by a lack of financial and technological resources, imposes a burden on both the family and the State. A wheelchair is a form of assistive technology which eases that burden for many. This study examines the impact of a simple, donated chair on the health, quality of life, and function of a subject population. MATERIAL/METHODS: Surveys were administered to 519 disabled recipients of a semi-rigid depot style wheelchair in 3 different countries at the time they received their chair and again after 12 months of use. Surveys evaluated physical and emotional health, functional independence, and lifestyle. RESULTS: On initial reports, 46.6% of subjects said they never left home, 52.3% were hospitalized one or more days/month, 70.3% reported daily pain, and 48.7% reported a negative mood state. Following 12 months of using the wheelchair, both the reported overall health rating and mood state increased by 20%; pain was significantly diminished. Although some areas in the ICF function measure improved more than others, the overall reported level of independence rose by 11%. CONCLUSIONS: A representative sample of the disabled in 3 countries of the world is socially isolated, in poor health, and with limited function. Receipt of a simple, depot style wheelchair significantly improved their quality of life, health indicators, and the ICF function measure following 12 months of use.

Reuse and refurbish: a cost savings delivery model for specialized seating.

OBJECTIVES: To describe a unique specialized seating delivery model for children with disabilities that focuses on cost containment and environmental preservation. To determine whether this delivery model achieves cost containment. DESIGN: A retrospective cost analysis using data from billing records and annual statistical reports of the specialized seating program, for the 2004 to 2009 billing period. SETTING: The specialized seating program is a service provided on a referral basis by the Saskatchewan Abilities Council, which is under contract to Saskatchewan Health. PARTICIPANTS: Pediatric patients (N=40) with physical disabilities (cerebral palsy, developmental delay, acquired brain injury, spinal cord injury, Down syndrome, other) who were referred, assessed, and met inclusion criteria. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: Relative cost (in Canadian dollars) of providing units with recycled components compared with purchasing new units. RESULTS: The average cost of a used wheelchair was Can $698.11. The average cost of a new chair was $2143.69, leading to an average savings per chair of $1445.58. Of the 49 chairs issued, this resulted in a total cost savings of $85,393.97. When labor costs were taken into account ($50,060.26), the savings amounted to $35,333.71. Overall cost reduction was 41.3%. CONCLUSIONS: A retrospective analysis shows evidence of cost containment. Long-term sustainability of the program requires ongoing analysis of the cost and environmental advantages of a recycling program and review of benefits provided in relation to the ability to meet patient needs. This delivery model does incorporate accountability and a policy framework, which could serve as a model for other centers.

Wheeled mobility (wheelchair) service delivery: scope of the evidence.

Identifying the appropriate wheelchair for a person who needs one has implications for both disabled persons and society. For someone with severe locomotive problems, the right wheelchair can affect mobility and quality of life. However, policymakers are concerned about the increasing demand for unnecessarily elaborate chairs. The Office of Inspector General, U.S. Department of Health and Human Services, issued 4 reports between 2009 and 2011 detailing fraud and misapplication of Medicare funds for powered wheelchairs, more than a decade after similar concerns were first raised by 4 contractors who process claims for durable medical equipment. Subsequent concerns have arisen about whether some impaired persons who need wheeled mobility devices may now be inappropriately denied coverage. A transparent, evidence-based approach to wheeled mobility service delivery (the matching of mobility-impaired persons to appropriate devices and supporting services) might lessen these concerns. This review describes the process of wheeled mobility service delivery for long-term wheelchair users with complex rehabilitation needs and presents findings from a survey of the literature (published and gray) and interviews with key informants. Recommended steps in the delivery process were identified in textbooks, guidelines, and published literature. Delivery processes shared many commonalities; however, no research supports the recommended approaches. A search of bibliographic databases through March 2011 identified 24 studies that evaluated aspects of wheeled mobility service delivery. Most were observational, exploratory studies designed to determine consumer use of and satisfaction with the process. The evidence base for the effectiveness of approaches to wheeled mobility service delivery is insufficient, and additional research is needed to develop standards and guidelines.
