Abstract
We present a random walk, fractal analysis of the stride-to-stride uctuations in the human gait
rhythm. The gait of healthy young adults is scale-free with long-range correlations extending over
hundreds of strides. This fractal scaling changes characteristically with maturation in children
and older adults and becomes almost completely uncorrelated with certain neurologic diseases.
Stochastic modeling of the gait rhythm dynamics, based on transitions between di erent "neural
