In this paper, we study dynamic stability during running, focusing on theeffects of speed and the use of a leg prosthesis. We compute and compare themaximal Lyapunov exponents of kinematic time-series data from subjects with andwithout unilateral transtibial amputations running at a wide range of speeds.We find that the dynamics of the affected leg with the running-specificprosthesis are less stable than the dynamics of the unaffected leg, and alsoless stable than the biological legs of the non-amputee runners. Surprisingly,we find that the center-of-mass dynamics of runners with two intact biologicallegs are slightly less stable than those of runners with amputations. Ourresults suggest that while leg asymmetries may be associated with instability,runners may compensate for this effect by increased control of theircenter-of-mass dynamics.
