Figure 2

Stride length from a PD patient while walking along a 30-m hallway as determined by chalk markings on the floor (blue squares) and the gait monitor (red circles). The top trace was acquired at the start of testing and the lower trace was acquired following 24-h of continuous gait monitoring. Accuracy in stride length measurement was maintained while wearing the gait monitor over the 24-h epoch.
