A novel portable and cost-efficient wheelchair training roller for persons with disabilities in economically disadvantaged settings: the EasyRoller.

Purpose: Stationary training rollers enable wheelchair users to maintain physical health and train as athletes, which serves to treat and prevent immobility-associated chronic disease and improve cardiorespiratory fitness required for sports performance. However, conventional exercise equipment is largely inaccessible for persons with disabilities in low-resource areas, primarily due to cost. The aim of this study was to prototype, develop, and test a portable, cost-efficient stationary training device for wheelchair users in low-resource settings - The EasyRoller.
