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 located toward back and side of the hip. It attaches the hip bone (ilium) to the upper leg (greater trochanter of the femur). Moves the thigh sideways away from the body. The front muscle fibers assists with twisting the thigh in toward the other leg and lifting the leg out in front of the body.
