The tensor fasciae latae is a small muscle arising from iliac bone and inserting it into the IT band. Together with the gluteus maximus the muscle assists in keeping the balance of the pelvis while standing, walking, or running.
"Tensor fasciae latae" translates from Latin to English as "stretcher of the sideband".
The basic functional movement of tensor fasciae latae is walking. The tensor fasciae latae is heavily utilized in horse riding, hurdling, and water skiing. Some problems that arise when this muscle is tight or shortened are pelvic imbalances that lead to pain in the hips, as well as pain in the lower back and lateral area of the knees
