Abstract :Time-series data of walking were abstracted by image sequence processing, and multivariate autoregressive model was adopted to three joint motions of hip, knee, and ankle, for the purpose of quantitative gait analysis in bind children. Multivariate AR parameters were investigated from the viewpoint of relative power contribution and impulse response. The results quantitatively described the characteristicts of gait in blind children which are qualitatively mentioned as shuffling walk. Another experiment was conducted to clarify the validity of the present technique in the viewpoint of potential energy and transmission efficiency in gait. Ground reaction force was measured in normal and pseudo-blind walk, and was compared to the results of multivariate AR analysis. It suggested that impulse respouse of mutivariate AR model exhibits the transmission efficiency in gait.
