Abstract

Gait analysis is a very important basis for reflecting the states of human movement. In this paper, a 3D motion capture system, an EMG signal collection device and two force plates were used to build up the gait analysis system for prosthesis wearers. And the system was used in the research and debug of the intelligent AK (above-knee) prosthesis. The results of clinical test indicated that: according to the analysis results of this system, appropriate control parameters can be used in the intelligent prosthesis adjusting, thus the amputees can have a better gait.
