Abstract
Cycling wheel chair (C-W/C) is a useful tool to provide a chance of physical exercise for the patients with severe impairment in lower extremities. We developed a new C-W/C with a round shaped steering system and examined the change of physical function before and 4weeks after training with this C-W/C for the patients with unilateral impairment of lower extremity. All of the patients could drive it and continue training during 4weeks. Maximum walking speed (MWS). score of Barthel index and driving speed of C-W/C (DS) significantly increased after training though grip strength and knee extension strength did not. Increment of MWS and DS during 4weeks (ΔMWS, ΔDS) and mean driving distances per week correlated each other. Furthermore, ΔDS correlated with the increment of cardio-respiratory fitness evaluated by metabolic equivalents. Physical training during 4weeks with C-W/C has a possibility to improve physical function through reinforcement of reciprocation in the lower extremities and efficient use of physical fitness.
