Abstract

Gait analysis, with the hip angle as parameter was investigated both for normal and simulated abnormal walk using Detrended Fluctuation Analysis (DFA) and Fast Fourier Transform (FFT). The two walking types were each attributed to different time scales; the long time scale corresponding to normal walking resulted to a scaling exponent close to 1.0. The short time scale corresponding to the abnormal walk resulted in a decrease of the scaling exponent towards uncorrelated randomness. Harmonics was observed using FFT for both walks and a decrease in the difference between the dominant frequencies for the abnormal walk.
