A physiological conditions feedback control method of gait trainer mainly includes: utilizing a physiological signal sensing circuit to detect the electromyographic signals of the trainee during gait training and perform the time-frequency analysis to the electromyographic signals; and, using a feedback control circuit to drive the gait trainer and utilizing the median frequency offset of electromyographic signals to determine the fatigue level of the user. When the muscle starts being fatigued, the median frequency of electromyographic signals in frequency domain will be lower than the initial median frequency; and then, the feedback control circuit will adjust the threshold value for triggering the gait generation circuit based on the offset of the median frequency. The present invention applies the progressive muscle over-load concept to flexibly adjust the training intensity for the user in real-time, so as to achieve good training result.
