	sEMG experimental group (n = 17)			sEMG control group (n = 13)
	Baseline	Post	p	Baseline	Post	p
CCI knee	0.40 ± 0.11	0.34 ± 0.14	0.042	0.38 ± 0.10	0.40 ± 0.18	0.196
CCI ankle	0.34 ± 0.23	0.30 ± 0.16	0.691	0.30 ± 0.17	0.27 ± 0.37	0.753

Values denote means ± SD unless specified otherwise. The skewed distributed variables (walking speed in baseline of the experimental group, symmetry index in the baseline of the experimental group, affected stride length in the baseline of the experimental group, unaffected stride length in the baseline of the control group, unaffected hip ROM in the baseline of the experimental group, unaffected knee flexion of the experimental group, FAC of two groups, 6MWT of the experimental group, CCI knee in post of the sEMG control group, and CCI ankle in post of the sEMG control group) were presented as median ± interquartile range (IQR).
