Study Design Cross-sectional laboratory study. Objectives To assess differences in hip strength, iliotibial band length, and hip and knee mechanics during running between male runners with iliotibial band syndrome and healthy controls. Background Flexibility, strength, and running mechanics are commonly assessed in patients with iliotibial band syndrome (ITBS). However, these variables have not been evaluated concurrently in this population. Methods Thirty-four males participated (17 healthy, 17 ITBS). Hip strength was measured with a hand held dynamometer and iliotibial band flexibility was assessed using an inclinometer while performing the Ober’s test. Kinetic and three-dimensional kinematic data were obtained during running. Kinematic variables of interest included frontal and transverse plane hip and knee joint angles at the time of early stance. Independent sample t-tests as well as effect sizes were used to assess group differences. Results Compared to the control group, persons with ITBS had a significantly lower Ober’s measurement (1.2°), weaker hip external rotators (1.2 Nm/kg), greater hip internal rotation (3.7°), and greater knee adduction (3.6°). However, only hip internal rotation and knee adduction exceeded the minimal detectable change score. Conclusions Our results suggest that intervention strategies that target neuromuscular control of the hip and knee may be indicated for males with iliotibial band syndrome.
