Effect of Peat Intervention on Pain and Gait in Patients with Knee Osteoarthritis: A Prospective, Double-Blind, Randomized, Controlled Study

Table 4

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

	Group	Before intervention		After intervention		value (intragroup analysis)^‡
		Mean ± SD	value (intergroup analysis)	Mean ± SD	value (intergroup 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
	Control group (n = 38)	10.180 ± 4.838		10.144 ± 4.926		0.975

SD: standard deviation. , 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.
