Gender differences in gait kinematics in runners with ITBS
Iliotibial band syndrome (ITBS) is a running injury synonymously associated with lateral knee pain. Despite ongoing research, a definitive consensus on the kinematic differences between those with and without ITBS has not been achieved. The current study sought out to investigate genetic differences between male and female runners with ITBS as well as differences between runners with ITBS and their non-afflicted counterparts.
96 runners were included in this study: 48 healthy and 48 with ITBS. After pre-screening, all participants underwent similar running conditions and kinematics was assessed with 3D gait analysis software while running on a treadmill.
Following the study, the authors found that females with ITBS exhibited significantly greater hip external rotation (ER) angles during swing phase (52-54% of gait cycle) when compared to male runners. Male runners with ITBS showed decreased hip adduction angles throughout swing phase as well as greater ankle internal rotation. These finding suggest that, females with ITBS should look to reduce hip ER while males with ITBS should focus on increasing ankle external rotation and hip adduction.
