How do weak hip abductors impact gait?

Weak hip abductors have a significant impact on gait, primarily leading to a lateral lean of the trunk toward the weaker side. This happens because the hip abductors, particularly the gluteus medius, are crucial for stabilizing the pelvis during the single-limb stance phase of walking. When these muscles are weakened, they are unable to maintain proper pelvic alignment. As a compensatory mechanism, individuals may lean their body toward the side of the weakness, which helps to bring the center of mass closer to the support base and reduce the demand on the impaired muscles.

This lateral lean aids in preventing excessive pelvis drop on the opposite side, allowing for greater stability during gait. However, it can also lead to inefficient movement patterns and potential issues in other regions of the kinetic chain due to altered mechanics. Understanding this relationship is essential for addressing gait abnormalities in individuals with weak hip abductors, as the adaptation may impact overall mobility and functional performance.
