Document Summary
Runners- pain in it band, knee pain- can actually be from origin of. Tensor fascia lata- contract and tighten it band during flexion- innervated by superior gluteal nerve. Posterior muscles of thigh with origin on the pelvis- butt muscles . Fibers run at a 45 degree angle. F: the major extensor" of the thigh also laterally rotates and abducts thigh. O: between anterior and posterior gluteal lines on lateral surface of ilium. F: abducts and medially rotates thigh, also steadies the pelvis during walking. I: via a tendon into the greater trochanter of the femur. O: between anterior and inferior gluteal lines on external surface of ilium. F: abducts and medially rotates thigh also steadies/levels the pelvis during walking (same as medius) Walking- when on 1 foot, keeps pelvis level so you can swing leg through. Dropping right side- means that left side isn"t keep it up to properly swing leg.
