Gait Phase Detection for Lower Limb Prosthetic Devices (original) (raw)

Biosystems & Biorobotics, 2018

Abstract

A prosthesis is an electronic-mechanical device that allows the replacement of a lost limb functionality. These features require strict control of the energy used for increment the operating time and patient’s safety. In lower limb prosthetic control, it is fundamental to detect each of the phases of the human gait cycle. For example, during the swing phase, the prosthesis must duplicate the movement of the healthy limb, and in load phase, this movement must be adapted. This article presents the algorithm for spatiotemporal human gait parameter using Teager-Kaiser energy operator and its partial validation.
