Table 4.

Range of motion of knee joint at frontal plane in peat intervention and control groups.

	Group	Before intervention		After intervention		p value (intragroup analysis)^‡
	Group	Mean ± SD	p value (intergroup analysis)^†	Mean ± SD	p value (intergroup analysis)^†	p value (intragroup analysis)^‡
Knee varus/valgus range of motion (degree)	Peat group (n = 44)^∗∗	11.455 ± 6.007	0.298	8.439 ± 3.605	0.082	0.006^∗
Knee varus/valgus range of motion (degree)	Control group (n = 38)^∗∗	10.180 ± 4.838		10.144 ± 4.926		0.975

SD: standard deviation. ^∗p < 0.05, significant difference at intergroup and intragroup comparing. ^∗∗Because the data are about both knees, the number of participants doubled. ^†Comparison between peat intervention and control group, Student's t test. ^‡Comparison between before- and afterintervention, paired t test.
