![]() ![]() The gluteus maximus paralysis is more obvious in case of muscular dystrophy. When paralysis of gluteus maximus occurs, the person feels difficulty to stand up from the sitting posture without the support. It works with the semitendinoses and semimembranoses to extend the hip. Gluteus maximus is one of the strongest muscle in the human body. Gluteal muscle weakness has been proposed to be associated with a number of lower limb injuries. Research has indicated that contraction of the deep abdominal muscles may assist with the contraction of gluteus maximus to assist with the control of anterior pelvic rotation.Gluteus maximus can be trained to produce functional knee extension when quadriceps femoris is weak or paralyzed. If the gluteus maximus is paralyzed climbing stairs and running will become very difficult however, other muscles can extend the hip.Eccentric control is also provided when bending forward. Gluteus maximus and the hamstrings work together to extend the trunk from a flexed position by pulling the pelvis backwards,eg standing up from a bent forward position.As a powerful extensor of the hip joint, the gluteus maximus suited to powerful lower limb movements eg stepping onto a step, climbing or running but is not used greatly during normal walking.Essential for maintaining an erect posture.Image: Gluteus maximus muscle (highlighted in green) - Posterior view Anatomy When the thigh is flexed the lower border of Glutes Maximus moves superiorly, exposing the ischial tuberosit subcutaneously (in sitting you sit on the ishial tuberosity, ischial bursae, subcutaneous fat and skin). The ischial tuberosity can be felt deep to the lower part of the Glutes maximus.Gluteus maximus covers all of the gluteal muscles except for the antero_superior third of the Glutes medius.The development of the muscle's function is associated with the erect posture and changes to the pelvis, now functioning to maintain the erect posture, as a hip extensor. Gluteus Maximus's size allows it to generate a large amount of force (the muscle evolved from an adductor of the hip which is still seen in lower primates today). ![]() It is the largest muscle at the hip representing 16% of the total cross-sectional area. It is the most superficial of all gluteal muscles that are located at the posterior aspect of the hip joint. Gluteus Maximus the largest and heaviest muscle in the body. ![]()
