Which muscle weakness can exacerbate ITB syndrome?

Which muscle weakness can exacerbate ITB syndrome?

• A. Weak gastrocnemius.
• B. Tight tensor fascia latae.
• C. Strong hip abductors.
• D. Weak hip abductors.

Answer: (D)

Weak hip abductors allow the pelvis to drop and the thigh to move inward during stance, increasing hip adduction and potential internal rotation. ThisToward alignment change tightens and tensions the iliotibial band as it travels past the lateral knee, raising friction where it rubs over the lateral femoral epicondyle and often worsening ITB syndrome. A tight tensor fascia latae can contribute by pulling on the IT band, but the question focuses on weakness, and strong hip abductors would actually reduce the risk, not worsen it. Weak gastrocnemius affects ankle push-off more than the direct frontal-plane mechanics that drive ITB friction.
