Abstract :
The purpose of this investigation was to develop and test quantitative measures to assess the dynamic stability of human locomotion in normal and pathologic gait. Through computer simulation the stability of joint trajectories were specified under a variety of conditions. The resulting joint trajectory time series data were used to calculate the overall stability of the walking using Floquet analysis. The results of these studies indicate that pathological gait resulting in loss of stability can be quantified and will produce lower stability measures as compared to normal gait
