Hip adduction is a strengthening exercise for the piriformis muscle. A cable attached at the ankle can be used to adduct the hip, bringing the leg in toward the opposite side of the body. The same equipment can also be used for hip abduction, where the leg starts beside the opposing leg and moves out to the side, away from the body.
The lateral rotator group is a group of six small muscles of the hip which all externally (laterally) rotate the femur in the hip joint.It consists of the following muscles: piriformis, gemellus superior, obturator internus, gemellus inferior, quadratus femoris and the obturator externus.
Piriformis syndrome occurs when the piriformis irritates the sciatic nerve, which comes into the gluteal region beneath the muscle, causing pain in the buttocks and referred pain along the sciatic nerve. [8] This referred pain is known as sciatica. Seventeen percent of the population has their sciatic nerve coursing through the piriformis muscle.
The fascia of the piriformis is very thin and is attached to the front of the sacrum and the sides of the greater sciatic foramen; it is prolonged on the muscle into the gluteal region. At its sacral attachment around the margins of the anterior sacral foramina it comes into contact with and ensheathes the nerves emerging from these foramina.
The piriformis nerve, also known as the nerve to piriformis, is the peripheral nerve that provides motor innervation to the piriformis muscle. Structure [ edit ]
Sacroiliac joint dysfunction is an outcome of either extra-articular dysfunction or from intraarticular dysfunction. SI joint dysfunction is sometimes referred to as "sacroiliac joint instability" or "sacroiliac joint insufficiency" due to the support the once strong and taut ligaments can no longer sustain.
It exits the pelvis through the greater sciatic foramen superior to the piriformis muscle. [2] [3] [4] It is accompanied by the superior gluteal artery and the superior gluteal vein. [2] It passes lateral-ward in between the gluteus medius muscle and the gluteus minimus muscle, [1] [5] accompanied by the deep branch of the superior gluteal ...
The exercise is performed from a seated position while the weight rests on the upper leg, just above the knee. The person engaged in this exercise lifts the weight by pushing down on the balls of the feet. [1] Due to the discomfort of higher weights on a bar, barbells used for seated calf raises are frequently padded or wrapped in a towel.
