There are a few things to look for when it comes to failing the test. If your lowered leg extends out straight instead of bending at the knee, your rectus femoris (the quad muscle) is tight. If ...
All four parts of the quadriceps muscle attach to the patella (knee cap) by the quadriceps tendon. The rectus femoris is situated in the middle of the front of the thigh; it is fusiform in shape, and its superficial fibers are arranged in a bipenniform manner, the deep fibers running straight (Latin: rectus) down to the deep aponeurosis.
If the iliopsoas muscle is shortened, or a contracture is present, the lower extremity on the involved side will be unable to fully extend at the hip. This constitutes a positive Thomas test. [ 2 ] Sometimes, with a very flexible patient, the Thomas test will be normal despite a psoas dysfunction being present.
It was found that the leading cause for the incidence of the disease was regular sport practicing and shortening of the rectus femoris muscle in adolescents that were in the pubertal phase. [42] For there is a 76% prevalence of patients with a shortened rectus femoris in those who have the Osgood-Schlatter's disease. [42]
When tight hip flexors accompany tight hamstrings, releasing your hip flexors to restore a neutral pelvis is the only way to release your hamstrings as well. Why the 3-way hip flexor release works
Lie facedown, arms out to sides and legs straight. Bend right knee, lifting foot toward ceiling. Gently rotate hips to the left as you drop right foot toward outside of left hip.
Many large and small muscles have relationships with the ligaments of the sacroiliac joint including the piriformis (see "piriformis syndrome", a condition often related with sacroiliac joint dysfunction), rectus femoris, gluteus maximus and minimus, erector spinae, latissimus dorsi, thoracolumbar fascia, and iliacus.

Tightness of the iliopsoas results in a dancer having difficulty lifting their leg into high positions. Abdominal muscles being weak and the rectus femoris of the quadriceps being tight are signs that improper muscles are being worked while dancing which leads to lumbar hyperlordosis. The most obvious signs of lumbar hyperlordosis are lower ...
