A patient balancing on their left leg has their right pelvis drop inferiorly. Which muscle needs strengthening?

When a patient balances on their left leg and the right pelvis drops inferiorly, it indicates a weakness in the muscles that stabilize the pelvis on the standing leg side. In this scenario, the right gluteus medius is responsible for maintaining the level of the pelvis when the person is standing on the left leg.

The gluteus medius is a key muscle in stabilizing the hip and preventing the pelvis from tilting. If the right gluteus medius is weak or not functioning properly, the pelvis on the right side will not be supported adequately, causing it to drop. Strengthening the left gluteus medius would not solve the problem since it is the right side that is failing to provide the necessary support.

Therefore, strengthening the right gluteus medius is crucial to correct the pelvic drop and restore balance during single-leg stance activities. This highlights the importance of the right gluteus medius in maintaining pelvic alignment during dynamic movements.
