Objective In order to maximumly remain the residual function of the lower residual limbs of amputation patient, and sufficiently bring in to full play of prosthesis, a rehabilitative training system of lower residual limbs was developed. Method The system comprises two parts: hip-joint training system and knee-joint training system, which could make the joint active angle improved, increase muscle volume of the residual limb and boost the concrescence of residual limb. Result Based on multidisciplinary research, the rehabilitative training system has finally developed. Conclusions With this system, it could be realized to improve the function of the amputation patients, promote the residual limbs setting and improve the conditions needed in assembling prosthesis fundamentally.
