Changes in Limb Kinematics

	RHL to Body Lateral Distance (cm) P = 0.105	RFL to Body Lateral Distance (cm) P < 0.001	RHL Swing Width (cm) P < 0.001	RFL Swing Width (cm) P < 0.001	RHL Swing Width Variation (cm) P < 0.001	RFL Swing Width Variation (cm) P < 0.001
Before (n = 14)	3.2 ± 1.0	7.3 ± 1.3	1.3 ± 0.4	1.5 ± 0.5	1.5 ± 0.6	1.8 ± 0.6
After (n = 14)	3.7 ± 0.9	11.7 ± 0.8	3.2 ± 0.6	3.4 ± 0.6	2.8 ± 0.7	3.5 ± 1.0

For the P values, seven matched speeds (0.63–0.89 m/sec) were used for a paired t test. Two experiments for “before” data (7 × 2 = 14, 10/28/05 and 11/03/05) and two experiments for “after” data (5/10/06 and 5/11/06).
