Wheelchair ergometer. Development of a prototype with electronic braking

Abstract

A new wheelchair ergometer is described which compensates for the pulsating character of the work by an automatic control system. This makes it possible to maintain a constant level of power during wheelchair work. Design: An automatic control system has been integrated in an electronically braked bicycle ergometer, and a pedal unit from Rodby Elektronik bicycle ergometer RE 820 has been coupled to a modified test wheelchair. With this device, the physical working capacity during submaximal circumstances can be tested in handicapped persons.
