Final answer:
When the feet overly pronate, internal rotation occurs at the hips as a compensatory action, which involves medial rotation of the femur to re-stabilize the body's alignment.
Step-by-step explanation:
When the feet overly pronate, the compensatory actions that occur at the hips are internal rotation. Overpronation refers to the excessive inward roll of the foot upon landing, which can lead to various alterations in the alignment and movement patterns of the body. To compensate for the instability caused by overpronation, the hips may respond by rotating internally. This medial rotation of the femur at the hip joint helps to realign the leg and provide a more stable base of support for each step.
Overpronation of the foot is often associated with flat feet and can increase the stress on the ankles, legs, hips, and back. It can also be linked to injuries related to running and walking. In some cases, overpronation can be addressed through strengthening exercises, stretching, and the use of custom orthotics to support proper foot alignment.
