Abstract
Prosthesis is often used to restore the appearance and functional mobility to individuals following limb amputatio n. The purpose of this study is to investigate the correlation between the electromyogram (EMG) signals with the rectication of patellar tendon bearing (PTB) socket. Six PTB sockets are manufactured with di erent compression depths at the patellar tendon region. Experiments for the subject are carried out to obtain the EMG signals using EMG telemetry system. From this study, it is found that there exists some kinds of pattern as the depths of PTB rectication is changed. As the PTB rectication depth is increased, the EMG activity rises generally yet in an N pattern for the quadriceps group for both left and right legs of the amputee. The results of this case study will lead to an appropriate range of rectication depths for prosthetists in the manufacturing of PTB sockets, and perhaps the identication of the most suitable depth for optimum transtibial amputee ambulation.
