which is an enlargement of the thyroid gland resulting from its overstimulation by elevated levels of TSH the TSH is elevated because there is little or no thyroid hormone in the circulation
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. 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 gluteus medius is one of three muscles that make up the gluteals. It, along with the gluteus minimus, abducts (lift the leg away from the body) and internally rotates the hip. During the mid-stance phase of running (or walking), the gluteus medius must contract to stabilize the femur and pelvis.
