Changes of velocity, gait cycle time, and cadence in peat intervention and control groups.


	Group	Before intervention		After intervention		value (intragroup analysis)
	Group	Mean ± SD	value (intergroup analysis)	Mean ± SD	value (intergroup analysis)	value (intragroup analysis)

Velocity (m/s)	Peat group (n = 22)	0.781 ± 0.144	0.876	0.873 ± 0.106	0.006	0.002
Velocity (m/s)	Control group (n = 19)	0.772 ± 0.195		0.727 ± 0.191		0.180

Gait cycle time (second)	Peat group (n = 22)	1.344 ± 0.240	0.977	1.297 ± 0.248	0.634	0.058
Gait cycle time (second)	Control group (n = 19)	1.346 ± 0.168		1.330 ± 0.188		0.542

Cadence (steps/min)	Peat group (n = 22)	91.774 ± 13.526	0.694	95.284 ± 14.652	0.368	0.035
Cadence (steps/min)	Control group (n = 19)	90.327 ± 9.756		91.675 ± 10.610		0.440

SD: standard deviation. , significant difference at intergroup and intragroup comparison. Comparison between peat intervention and control groups, Mann–Whitney test. Comparison between before- and afterintervention in each group, Wilcoxon signed-rank test.
