- Abstract
- Objective: Movement dysfunction increases lower extremity injury risks. This study identified modifiable factors (neuromuscular control [EMG] and ranges of motion) that contribute to dysfunctional movement (lateral hip shift) during an overhead squat. Methods: Participants were assigned to the hip shift or control groups based on overhead squat performance. Gluteal and hip adductor EMG was sampled during the overhead squat. Hip internal and external rotation, hip abduction, knee extension, and dorsiflexion ranges of motion were assessed. Mixed-Model ANOVAs analyzed differences. Results: The hip shift group had less hip abduction and gluteus medius activation in the limb shifted toward compared to the control group. No other differences were observed. Conclusion: The EMG and range of motion measurement differences between groups may further increase the hip shift group's injury risk. The differences observed may increase injury risk of both the limb shifted toward as well as the contralateral limb.
