METHOD FOR CONTROLLING GAIT-TRAINING APPARATUS USING BIOFEEDBACK

摘要

A method for controlling gait-training apparatus using biofeedback is provided. A biosignal-detecting loop is used to detect and analyze the electromyographic signal of a user using the gait-training apparatus. A feedback control loop is used to drive the gait-training apparatus and determine the fatigue level of the user. When the user's muscle starts to become fatigue, the feedback control loop can further adjust the threshold for triggering the gait-training apparatus to retain the training session so that the training intensity can be regulated on-line and the user's muscle can be trained effectively based on the concept of progressive overload.

1. A method for controlling a gait-training apparatus using biofeedback, comprising steps of:
a) detecting and analyzing an electromyographic signal of a user in the time domain and the frequency domain, and performing gait training on the gait-training apparatus by using a biosignal-detecting loop; b) driving the gait-training apparatus and determining the user's fatigue level by a feedback control loop,
i) in the time domain, when the electromyographic signal reaches a threshold, the feedback control loop triggers a gait-generating loop to drive the gait-training apparatus; In the beginning, the threshold is an initial threshold;ii) in the frequency domain, the feedback control loop determines the fatigue level of the user's muscle during gait training based on the extent of median frequency shift; c) When the median frequency of the user's electromyographic signal is lower than an initial median frequency, the feedback control loop adjusts the threshold for triggering the gait-generating loop according to the extent of median frequency shift.
