The Application of Balance Capacity's Test for Wearer of Low Limb Prosthesis Based on Fast Fourier Transform (FFT)

Balance capacity's test could offer some valuable datum, when the adjustment of suitability or the evaluation of rehabilitation training is made for the wearer of low limb. In the research, based on FFT, the datum of the track of the body gravity movement are processed to acquire datum of amplitude-frequency of the track of body gravity movement, thus an index of evaluation for body's balance capacity can be gotten.
