Table 1. Pretreatment (Pre) and post-treatment (Post) measures of pain intensity, the 50-ft walk time, hamstring strength, and quadriceps strength.

	Pain intensity (visual analogue scale)		50-foot walk test (seconds)		Hamstring strength (kg)		Quadriceps strength (kg)
	Pre	Post	Pre	Post	Pre	Post	Pre	Post
Mean ± SD	7.1 ± 1.1	3.8 ± 1.3	14.3 ± 1.4	12.7 ± 1.6	39.3 ± 2.8	42.2 ± 2.8	43.1 ± 3.1	45.8 ± 3.7

Paired t-test showed that there were significant improvements between pre and post-test in measures of pain, the 50-ft walk time and hamstring strength (p≤0.0001)and quadriceps strength (p≤0.001).
