Parameter	Experimental group		Control group
Parameter	Before	After	Before	After
Ankle joint angle (°)	17.81 ± 4.50	25.42 ± 4.85^b^,^c	18.83 ± 2.31	22.49 ± 3.38^a
Knee joint angle (°)	34.72 ± 9.80	50.21 ± 14.34^b^,^c	34.82 ± 10.20	42.29 ± 11.12^a
Centre of gravity lateral displacement (left-right direction, cm)	13.35 ± 3.16	8.15 ± 2.31^b^,^c	12.63 ± 2.87	9.97 ± 3.27^a

Comparison with before treatment: ^aP < 0.05, ^bP < 0.01; comparison with the control group: ^cP < 0.05.
