The gluteus medius (GM) is thought to play an important role in stabilizing the pelvis
and controlling femoral adduction and internal rotation during functional activity. GM weakness, resulting
in decreased stabilization and control, has been suggested to be related to lower extremity dysfunction and
injury. Many clinicians focus on strengthening the GM to improve lower extremity kinematics for the prevention
and rehabilitation of injury. An indirect way to measure GM strength is through electromyography. It
is generally assumed that exercises producing higher levels of activation will result in greater strengthening
effects.3 Understanding what exercises result in the greatest level of GM activation will assist clinicians in their
injury prevention and rehabilitation efforts. Focused Clinical Question: In a healthy adult population, what
lower extremity exercises produce the greatest mean GM activation, expressed as a percentage of maximum
voluntary isometric contraction?
