Awareness and capacity building in appropriate wheelchair services for developing contexts globally.
Personal mobility is a human right that allows individuals with disability to participate in everyday life. The World Health Organization (WHO) estimates 70 million people worldwide need a wheelchair for functional mobility. To address this need, WHO developed wheelchair service guidelines and training packages to increase awareness, service provider capacity, and appropriately train relevant personnel in wheelchair service provision, with a focus on less-resourced settings. In the North West Region (NWR) of Cameroon, those responsible for the dissemination and roll out of wheelchairs often procured through donations from non-governmental organizations include physiotherapists, physiotherapy assistants, field workers, and technicians at community based and center based rehabilitation clinics. However, a low level of awareness exists among service providers in the NWR on appropriate wheelchair service delivery and the WHO wheelchair guidelines and training resources available. Furthermore, there is a lack of capacity at the various levels of wheelchair service provision (as referenced by WHO) which may have caused challenges within the service delivery systems. As a result, the difficulties may have contributed to individuals with mobility impairments in the region not receiving the wheelchair or mobility device that best meets their needs, creating a barrier to work, education, and social inclusion. Therefore, my current work explores wheelchair service provision in the NWR of Cameroon, including the introduction to and feasibility of implementing the WHO guidelines and resources to facilitate appropriate service delivery and ultimately the inclusion of wheelchair users in Cameroonian society. To date, an observational analysis has been conducted with 3 rehabilitation clinics servicing wheelchair users in the NWR. After observation, service providers participated in an 8-hr workshop in wheelchair service provision based on WHO training packages. The workshop included focus groups discussing barriers to implementing appropriate wheelchair service delivery, and thematic analysis grouped responses corresponding to the WHO Guidelines on the Provision of Manual Wheelchairs in Less-Resourced Settings. The work recommends to key stakeholders ways to enhance wheelchair service delivery in the NWR. The results will set the foundation for building capacity in appropriate wheelchair services and increasing societal participation for wheelchair users in Cameroon.
Abstract: This study was conducted to compare the performance of three types of chairs in a low-resource setting. The larger goal was to provide information which will enable more effective use of limited funds by wheelchair manufacturers and suppliers in low-resource settings.The Motivation Rough Terrain and Whirlwind Rough Rider were compared in six skills tests which participants completed in one wheelchair type and then a day later in the other. A hospital-style folding transport wheelchair was also included in one test. For all skills, participants rated the ease or difficulty on a visual analogue scale. For all tracks, distance traveled and the physiological cost index were recorded. Data were analyzed using repeated measures analysis of variance.The Motivation wheelchair outperformed Whirlwind wheelchair on rough and smooth tracks, and in some metrics on the tight spaces track. Motivation and Whirlwind wheelchairs significantly outperformed the hospital transport wheelchair in all metrics on the rough track skills test.This comparative study provides data that are valuable for manufacturers and for those who provide wheelchairs to users. The comparison with the hospital-style transport chair confirms the cost to users of inappropriate wheelchair provision. Implications for Rehabilitation For those with compromised lower limb function, wheelchairs are essential to enable full participation and improved quality of life. Therefore, provision of wheelchairs which effectively enable mobility in the cultures and environments in which people with disabilities live is crucial. This includes low-resource settings where the need for appropriate seating is especially urgent. A repeated measures study to measure wheelchair performances in everyday skills in the setting where wheelchairs are used gives information on the quality of mobility provided by those wheelchairs. This study highlights differences in the performance of three types of wheelchairs often distributed in low-resource settings. This information can improve mobility for wheelchair users in those settings by enabling wheelchair manufacturers to optimize wheelchair design and providers to optimize the use of limited funds.

Abstract: 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.

Abstract: Wheelchairs for children with impaired mobility provide health, developmental and psychosocial benefits, however there is limited understanding of how mobility aids affect the health-related quality of life of children with impaired mobility. Preference-based health-related quality of life outcome measures are used to calculate quality-adjusted life years; an important concept in health economics. The aim of this research was to understand how young wheelchair users and their parents define health-related quality of life in relation to mobility impairment and wheelchair use.The sampling frame was children with impaired mobility (≤18 years) who use a wheelchair and their parents. Data were collected through semi-structured face-to-face interviews conducted in participants' homes. Qualitative framework analysis was used to analyse the interview transcripts. An a priori thematic coding framework was developed. Emerging codes were grouped into categories, and refined into analytical themes. The data were used to build an understanding of how children with impaired mobility define health-related quality of life in relation to mobility impairment, and to assess the applicability of two standard measures of health-related quality of life.Eleven children with impaired mobility and 24 parents were interviewed across 27 interviews. Participants defined mobility-related quality of life through three distinct but interrelated concepts: 1) participation and positive experiences; 2) self-worth and feeling fulfilled; 3) health and functioning. A good degree of consensus was found between child and parent responses, although there was some evidence to suggest a shift in perception of mobility-related quality of life with child age.Young wheelchair users define health-related quality of life in a distinct way as a result of their mobility impairment and adaptation use. Generic, preference-based measures of health-related quality of life lack sensitivity in this population. Development of a mobility-related quality of life outcome measure for children is recommended.

Abstract: 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.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.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).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.

Abstract: To describe a 6-month follow-up of a specialized paediatric wheelchair and seating programme in Haiti.Descriptive design using a structured survey and open-ended questions.Concurrent with a seating and wheelchair programme conducted in northern Haiti, beneficiaries and their families were introduced to the study, and 86 of 91 consented to future contact. A survey was developed with input from international and local partners, and administered by face-to-face or telephone interviews. Donated wheelchairs were assessed in 5 categories: wheelchair utilization, maintenance, fit, environmental access, and perceived benefits of wheelchair use.A total of 57 beneficiaries (age range < 2-31 years) were located 6 months after receiving their custom-fit wheelchair and consented to the survey. All respondents still had the wheelchair, 70.2% were using it a minimum of 3-5 days/week, 17.5% were using it < 3 days/week and 12.3% were not using it at all. Primary reasons for not using the wheelchair were that it was broken, uncomfortable, or difficult to transport. The commonly reported benefits were improved mobility, independence, participation and social interaction.The majority of people who received customized wheelchairs continued to use their equipment 6 months later, with predominantly beneficial outcomes. In future seating initiatives in low-resource settings, efforts to optimize equipment durability and training of local technicians should be supported and evaluated.

Abstract: The government of Tanzania created opportunity for the production of wheelchairs that would be appropriate to the local needs and environment.The study assessed the extent to which the wheelchairs met the activity and participation needs of the users, as well as the users' level of satisfaction with the provision, repair and maintenance of these wheelchairs.A descriptive cross-sectional analytical design was utilized to collect data through the administration of a questionnaire among 75 adult wheelchair users.Participants had used wheelchairs for an average period of 9.3 years. Most participants (61%) had sustained spinal cord injuries, and used three-wheeler chairs (76%). More than 90% reported that their wheelchairs positively influenced their activity and participation needs, and 85% were satisfied with their ability to carry out daily activities. Participants expressed satisfaction with the durability of the wheelchairs (89%), and the professional services received (71%), but not with follow-up services (77%). There was difference in satisfaction with features of 3-wheeler and 4-wheeler rigid chairs (p=0.030).The wheelchairs positively impacted participants' activity and participation needs. Participants were sat isfied with the features of the wheelchairs but not with follow-up services. The concerns of dissatisfied users should be addressed.
