ABSTRACT
Current wheelchairs used in low-resource settings lack the adjustability required for children with cerebral palsy and are not well-suited for rough terrain environments. This study aimed to examine the durability and functional interface of two wheelchairs specifically designed for use in low-resource settings. This descriptive study assessed 14 wheelchairs used by children with cerebral palsy living in Kenya, Africa (Momentum Wheels for Humanity's Liberty II wheelchair n = 6, Beeline's Honey Bee wheelchair n = 8). Four physical and occupational therapists evaluated durability using the Wheelchair Components Questionnaire (WCQ) and functionality using the Wheelchair Interface Questionnaire (WIQ). Medians were used to compare differences in the chair types using the Wilcoxon-Mann-Whitney test in Statistical Analysis Software (SAS) 9.4 with an alpha = 0.05. Median scores on the WCQ were 8.3/10 for the Liberty II and 7.8/10 for Beeline's Honey Bee wheelchair; however, the durability of the wheel locks was lower in the Beeline wheelchair (5.1/10 compared to the Liberty II 8.1/10 (p = 0.002). Median scores on the WIQ were lower and significantly different in the area of preventing distal lower extremity pain (Liberty II =3.7/10 and Beeline = 7.6/10, p = 0.045). Low scores occurred in both chairs in the areas of transfers and transporting the chairs in the community. The Beeline wheelchairs demonstrated higher average ratings for all areas of the WIQ, indicating the wheelchairs fit the children better and were more functional for use in the home and community environment.
Beeline Honey Bee and Clasp Liberty II wheelchairs demonstrate strengths supporting children in their communities, although no single type of wheelchair is perfect for children with cerebral palsy in low to middle-income countries with rough terrain.Rehabilitation professionals can use their physiological expertise to provide feedback on durability and functionality of wheelchairs in collaboration with wheelchair manufacturers to provide the most durable, cost-effective assistive technologies that support the user's physiological needs.The appropriate provision of wheelchairs can increase the quality of life for the child and their families, enabling them to participate in their local communities more fully.
