Eleven participants completed the quality assurance study I. Seventy three percent of the participants were males. The participants had a mean age of 69.4 years of age with a diagnosis of mild to moderate PD for an average of 4.1 years. All were un-weighted to @ 50% of body weight to enable jogging/striding with reduced ground reaction forces. All but two participants achieved exercise heart rate. The two who did not achieve the desired heart rate were participants with pacemakers.
