Neuro-degenerative diseases often affect gait and mobility. To gain a better understanding of the pathophysiology of these diseases and to improve our ability to measure responses to therapeutic interventions, it may be helpful to quantify gait dynamics accurately. The data shown here are stride intervals (the time intervals between consecutive heel strikes of the same foot).
