Abstract
Atypical hip and knee kinematics caused by iliotibial band (ITB) tightness and/or weakness of the hip abductor contribute to iliotibial band friction syndrome (ITBFS). Therefore, most rehabilitation plans for treating ITBFS include exercises for increasing ITB flexibility and strengthening hip abductor and external rotator muscles to prevent hip adduction and medial rotation. This study compared the effects of 6–week ITB stretching and ITB stretching plus side–lying Figure 4 (Figure 4) turnout exercises (hip abduction and external rotation exercise) on lateral knee pain as well as the angles of pelvic lateral tilting, hip adduction and medial rotation and tibial medial rotation during single–leg small knee bend (SLSKB, 20° knee flexion) in subjects with ITBFS. A total of 26 male subjects with ITBFS (18 right legs and 8 left legs) were recruited from a workplace–based work–conditioning center in an automobile assembly plant in Wonju, Korea. Using random sampling numbers, the subjects were randomly assigned to one of the two groups: the ITB stretching group (stretching group, n=13) and the ITB stretching plus Figure 4 exercise group (stretching plus strengthening group, n=13). The kinematic data of the pelvis, hip, and knee were measured using a three–dimensional electromagnetic motion tracking system, the intensity of lateral knee pain was measured using a visual analog scale, ITB tightness was assessed using the Ober’s test and the hip abductor and external rotator strengths were determined using a hand–held dynamometer before and after the 6–week program. The results of this study showed that hip adduction, tibial medial rotation, ITB tightness and intensity of lateral knee pain were significantly decreased after the 6–week ITB stretching program (p < 0.05). The pelvic lateral tilt, hip adduction, hip medial rotation, tibial medial rotation, ITB tightness and lateral knee pain were significantly decreased, and the strength of the hip abductor and external rotator were significantly increased after the 6–week ITB stretching plus Figure 4 exercise program (p < 0.05). Compared with the stretching group and the stretching plus strengthening group showed significantly decreased angles of pelvic lateral tilt, hip adduction and tibial medial rotation as well as significantly increased strength of the hip abductor and external rotator (p < 0.05). Therefore, the ITB stretching plus Figure 4 exercise can be recommended for treating patients with ITBFS rather than ITB stretching alone.
