Changes in muscle activity of people with transtibial amputation when using a powered prosthesis

This abstract has open access
Abstract Summary
Kinematic and electromyography data were collected from nine participants with transtibial amputation (TTA) while walking over ground using a powered and a non-powered prosthesis. Peak EMG amplitude of the major thigh muscles was compared across prostheses and sides. There was no significant effect of prosthesis for any of the muscles tested. The lateral hamstring peak amplitude had a significant prosthesis x limb interaction effect (p = 0.018). However, paired t-tests revealed no significant differences in the peak amplitude of the lateral hamstring.
