Gait parameters of the PD-FOG NI group among FOG Time and N-FOG time.

Gait parameters	FOG Time	N-FOG Time	Statistical value	p-value	Cohen’s d
Stride length (cm)	50.14 ± 15.42	68.61 ± 25.71	4.090	<0.001	0.770
Gait velocity (m/s)	0.43 ± 0.21	0.63 ± 0.26	4.733	<0.001	0.890
Cadence (steps/min)	104.88 ± 18.11	111.74 ± 23.06	1.382	0.178	0.260

FOG Time, the period of 60–120 s in this experimental paradigm; N-FOG Time, the period of 150–210 s in this experimental paradigm; Cohen’s d, Cohen’s standardized mean difference.
