The piriformis rotates the thigh laterally. When the hip is flexed greater than 90 degrees it then it rotates the thigh medially.
Piriformis syndrome is caused by the piriformis muscle compressing the sciatic nerve, leading to pain and discomfort in the buttocks and down one leg. This compression can be a result of muscle tightness, injury, overuse, or anatomical variations in the piriformis muscle. Physical activities that involve repetitive movements or sitting for prolonged periods can also contribute to the development of piriformis syndrome.
It depends in which function. Femur flexion: Gluteus maximus, Hamstrings, Sartorius and parts of Adductor magnus. Adduction: Gluteus medius and minimus, Tensor Fascia latae, Sartorius, Piriformis. Flexion of the lumbar spine: Quadratus lumborum and Erector Spinae.
The joint action in leg extensions is knee extension, where the angle between the thigh and lower leg decreases. The main muscles involved in this action are the quadriceps, specifically the vastus medialis, vastus lateralis, vastus intermedius, and rectus femoris. The movement primarily occurs at the knee joint.
No, the rotator cuff is a group of muscles and tendons that support and stabilize the shoulder joint, not the elbow joint. The flexibility at the elbow joint is mainly due to the action of different muscles like the biceps and triceps.

Piriformis-- A muscle in the pelvic girdle that is closely associated with the sciatic nerve.
Physiotherapy aimed at relaxing tight piriformis muscles, hip external rotators and adductors, strengthen hip abductors, or that increase the mobility of the sacroiliac joint can be beneficial.
The piriformis is a small muscle located deep in the gluteal region, playing a key role in the lateral rotation and abduction of the hip joint. It helps stabilize the pelvis during movement and aids in activities such as walking, running, and climbing stairs. Additionally, the piriformis is significant for its anatomical relationship with the sciatic nerve, as irritation or tightness in this muscle can lead to piriformis syndrome, causing pain in the buttocks and down the leg.
Rathje was diagonsed with Piriformis Syndrome in late 2006. However, a double hernia was discovered in the summer of 2007 and he had surgery to correct it. He is confident that he can make a return to action for the 2007-2008 season.

The most effective piriformis myofascial release technique for relieving pain and tension is deep tissue massage combined with stretching exercises targeting the piriformis muscle.
National Joint Action Committee was created in 1969.
The piriformis originates at the anterior sacrum and inserts at the greater trochanter of the femur.
Joint Action Committee for Political Affairs was created in 1981.
