Gluteal Maximus Muscle Research Paper

adduction. Standing, where the fixed point is at the insertion on the femur, contraction will rotate the pelvis anteriorly[17].

2.2.2 Psoas
This muscle is only muscle group in human body with direct attachment to the spine, the pelvis and the femur. Therefore it has potential to influence, and influenced by movement at both of the spine and hip joints[18].

2.2.3 Gluteal maximus muscle: superficial group
The gluteus maximus muscle is the one of the largest muscle in the gluteal region and it covers most of the other gluteal muscles. It is quadrangular in shape and has a broad origin at the lateral surface of the ilium posterior to the linea glutea posterior, and along the dorsal surface of lower sacrum and the lateral surface of the coccyx to the external surface of the sacrotuberous ligament. There is also attachment to fascia overlying the gluteal medius muscle and between the ilium and sacrum, to fascia covering the erector spinae muscle. It covers diagonally downwards and laterally towards the femur. The upper two thirds and superficial lower part of the muscle radiate more laterally and insert into the posterior aspect of a tendinous thickening of the fascia lata (the iliotibial tract). Fascia lata later inserts laterally at the tibia and fibula. Thus, gluteus maximus and tensor fascia lata aid in providing lateral stability to the knee. The action of gluteus maximus muscle is with the pelvis fixed, extension and lateral rotation of the femur and with the femur fixed it will extend the pelvis on hip. It mainly extends the flexed thigh at the hip joint. It is insertion into the iliotibial tract, it also stabilizes the knee and …show more content…
It originates from the external surface of the ilium between the anterior gluteal line and posterior gluteal line and inserts on an elongate facet on the lateral surface of the greater trochanter (GT). This muscles abduct the lower limb
