![]() Conversely, athletic patients are often masters of compensation and may be able to keep the pelvis in neutral while the lower leg will adduct and internally rotate. As you can see in the photo below, weakness of the right gluteus medius will cause the left hip to drop when standing on the right limb. ![]() The role of the gluteus medius during activities such as walking and running is to dynamically stabilize the pelvis in a neutral position during single leg stance. This is apparent when looking at the mechanism of a Trendelenburg Gait. When you really break down the function of the gluteus medius, you see that it is far more valuable as a pelvis and lower extremity dynamic stabilizer than it is a pure hip abductor. ![]() I think this is a great topic of discussion as the role of the gluteus medius in normal function and rehabilitation has been receiving attention lately as attention is being paid to strengthening and training the body in the frontal plane of motion and out of the sagittal plane. The authors do a good job reviewing some of the basic anatomy and function of the muscle and relating this information to research reports looking at dysfunction and treatment of the muscle for several lower extremity injuries. The October 2008 issue of the Journal of Strength and Conditioning has an impressive review article of the anatomy, function, assessment, and strengthening of the gluteus medius from a group of clinicians in New Zealand.
