“Display off” columns present walking speed and stride length results for patients wearing the device with the display turned off. “Display on” columns show on-line performance results with the display turned on. “15-min Residual” columns present performance results after a 15-minute break, when patients walked freely with the device taken off.

1 Mean age.

2 Compared to baseline speed.

3 Compared to baseline stride length.
