Abstract
Despite the increasing number of studies that have examined the therapeutic effect of treadmill training programs in Parkinson's disease (PD), there has been little research to evaluate the modifications of gait induced by treadmill walking. We investigated spatiotemporal differences between treadmill and overground walking in patients with PD. PD patients significantly increased their step length and step height; and reduced their cadence, step width and step width variability on the treadmill in comparison with walking overground. PD patients are able to attenuate their short shuffling steps when walking on a treadmill.
