Stride length over time during timed 2-minute walking trials. The linear regression slope of stride length leading to the onset of FoG was examined. a, ASSIST OFF vs. ASSIST ON (Study Visit 1). Markers in light gray and red are for ASSIST OFF and ASSIST ON, respectively. The shaded regions in light gray indicate FoG episodes during ASSIST OFF (Linear regression: y = −4.65⋅10−3 × time + 1.15, n = 48 independent strides; a two-sided, one-sample t-test for the slope, P = 3.08⋅10−12, t = −9.37, df = 46). There was no FoG episode during ASSIST ON. b, NO SUIT vs. ASSIST ON (Study Visit 4). Markers in dark gray and red are for NO SUIT and ASSIST ON, respectively. The shaded regions in dark gray indicate FoG episodes during NO SUIT (Linear regression: y = −3.42⋅10−3 × time + 1.09, n = 66 independent strides; a two-sided, one-sample t-test for the slope, P = 2.45⋅10−16, t = −10.97, df = 64). There was no FoG episode during ASSIST ON.
