It can cause pain in the low or mid back, SI joint, hip, groin, thigh, knee, or any combination. The iliopsoas gets innervation from the L2-4 nerve roots of the lumbar plexus which also send branches to the superficial lumbar muscles. The femoral nerve passes through the muscle and innervates the quadriceps, pectineus, and sartorius muscles. It ...

The pectineus muscle is the most anterior adductor of the hip. The muscle's primary action is hip flexion; it also produces adduction and external rotation of the hip. It can be classified in the medial compartment of thigh [2] (when the function is emphasized) or the anterior compartment of thigh (when the nerve is emphasized). [3]
The rectus femoris, sartorius, and iliopsoas are the flexors of the thigh at the hip. The rectus femoris is a weaker hip flexor when the knee is extended because it is already shortened and thus suffers from active insufficiency ; the action will recruit more iliacus , psoas major , tensor fasciae latae , and the remaining hip flexors than it ...
Tight hip flexors are a surprising but common cause of chronic tension in your hamstrings — the muscles on the backs of your legs that stretch when you bend to touch your toes. Since hamstrings ...
For example, when one performs a sit-up that brings the torso (including the lower back) away from the ground and towards the front of the leg, the hip flexors (including the iliopsoas) will flex the spine upon the pelvis. Owing to the frontal attachment on the vertebrae, rotation of the spine will stretch the psoas.
Those with femoral nerve dysfunction may present problems of difficulties in movement and a loss of sensation. [medical citation needed] The patient, in terms of motor skills, may have problems such as quadriceps wasting, loss of knee extension and a lesser extent of hip flexion given the femoral nerve involvement of the iliacus and pectineus muscles.

The nerve of the anterior compartment of thigh is the femoral nerve. [2] Innervation for the quadriceps muscles come from the posterior division of the femoral nerve, while the anterior division (which contains cutaneous as well as muscular components) gives a lateral and a medial branch, the second being responsible for the innervation of the sartorius muscle.
