Discussion Consistent with previous studies, we find a reduced stride length and average swing time, and an increased stride time variability and swing time variability in patients with PD [11,14-20]. The key findings ... relationships between gait speed and these measures. Stride length, stride time, swing time, and stride time var- iability were related to gait speed, both on level ground and on the treadmill, most...
