Gluteus medius becomes active toward the very end of swing phase to do what?

• A. Prepare for heel contact
• B. Produce foot slap
• C. Lower the medial longitudinal arch
• D. Create toe drag

Answer: (A)

The key idea is how the gluteus medius helps position the leg for the next step. As the leg finishes swinging forward, the gluteus medius activates to stabilize the pelvis and control the alignment of the thigh so the foot lands under the body's center of gravity. This positioning prepares the limb for heel contact and smooth weight acceptance, preventing the pelvis from dropping on the opposite side and helping the hip, knee, and ankle meet the ground in a stable line. The other outcomes described don’t fit this late-swing preparation: a foot slap relates to rapid unloading at heel strike, lowering the medial arch involves foot arches and intrinsic muscles, and toe drag comes from inadequate toe clearance due to other joints’ control.
