Abstract :
Gait analyses show that knee moments are considerably different when walking on different terrain. To accommodate changing conditions, prostheses should provide a means for adjusting the knee moments by identifying conditions of the terrain. In this research, terrain identification is obtained by the use of electromyographic (EMG) signals that are used to control resistive moments of an above-knee prosthesis. Results from laboratory experiments demonstrate that the technique is effective for identification and adaptable to different terrain
