Influence of Shoe-heel Height of the Trans-tibial Prosthesis on Static Standing Biomechanics

Shoe-heel height has great influence on lower-limb amputees' biomechanics during static standing. This article mainly considers the load line of the prosthetic side in the sagittal plane and the electromyogram (EMG) data of the lower limb muscles. The results indicate that the load line and the EMG are greatly influenced by the shoe-heel height, however, the amputee subconsciously adjusts his standing manner to make himself more comfortable and natural. This will provide references for prosthesis design and alignment setting
