Abstract

The authors analyzed the frequency content of camera image plane data for markers on each body segment during gait. For each segment, they determined the low-pass filter cutoff frequency that balanced the amount of signal distortion and the amount of random noise passed. The frequency content of the data as measured by the cutoff frequency differed for different body segments, being higher for the lower limb segments and lower for the head. This result supports the hypothesis that the frequency content of the kinematics of segments decreases caudal to rostral
