Abstract
In order to study the frequency characteristic of body oscillation in the anterior-posterior (AP) direction during upright stance, 10 subjects were exposed to the motion platform with specific posture and followed the tracks of the passive motion stimulus, sinusoidal waveform, with the increasing frequencies (0.05-1.2Hz). By measuring the displacement of the center of gravity (COG), the bode diagram between the motion of platform and body’s COG was obtained. Results showed that the mean cut-off frequency (COF) is 0.5 Hz, the mean resonance frequency (RF) is 0.316 Hz and the bandwidth of the body oscillation is 0.1-0.5 Hz in AP direction. In a conclusion, this study reaches the frequency response of human dynamic balance under passive motion stimulus by using COG values, proposes a method based on the COF values to evaluate the balance ability, and provides data support for the research of balance ability in the medical community.
