How does the tensor fasciae latae work?
The tensor fasciae latae works in synergy with the gluteus medius and gluteus minimus muscles to abduct and medially rotate the femur. The TFL is a hip abductor muscle. To stretch the tensor fasciae latae, the knee may be brought medially across the body (adducted).
How do you stretch the tensor fasciae latae?
The TFL is a hip abductor muscle. To stretch the tensor fasciae latae, the knee may be brought medially across the body (adducted).
What is the function of the hip abductors and tensor fasciae?
Function. Both the hip abductors and the tensor fasciae latae counteract the pressure on the opposite side and help stabilize the bone (tension banding effect). Furthermore, the activation of the muscle leads to an abduction, flexion and inward rotation of the hip joint.
How does the fasciae latae stabilize the hip joint?
Together with gluteus maximus and the illiotibal band, it stabilizes the hip joint by holding the head of the femur in the acetabulum. The tensor of fasciae latae, together with the gluteus maximus contributes in stability of the knee during extension and also in partial flexion.
Which movement does the tensor fascia latae perform?
The main function of this muscle is to produce the extension and lateral rotation of the leg on the knee joint. Additionally, it contributes to the movements of the thigh, acting as a relatively weak abductor and medial rotator on the hip joint.
How does tensor fasciae latae work?
How to find your TFLFirst, lay on your back with your legs extended long.Next, locate your hip bones on either side.Place your hands by your side, next to your hip bones.Flexing one foot at a time, rotate your toes inward. You should feel a muscle fill up into your hand – Ta-Da! You have just found your TFL!
Does the TFL externally rotate the hip?
The Tensor Fasciae Latae, or TFL to its friends, is a small muscle in the outside front of the hips that works very, very hard. The TFL is a multi-tasker. It does hip flexion, hip abduction, internal rotation, and it even internally rotates the lower leg through its attachment to the IT band.
What is the action of tensor fascia latae TFL at the hip joint?
The tensor fasciae latae (TFL) is a muscle on the front of the hip that connects to the lower leg via the IT band. It is positioned above the gluteus minimus and some of the gluteus medius muscle. The functions of the TFL muscle are to help flex, abduct, and medially rotate the hip.
What does TFL compensate for?
The TFL helps to also stabilize a straight knee when standing and assists in internally rotating your leg (rotating your whole leg to point your toes towards the center of your body). If your gluteus medius and maximus are weak and your TFL takes over, it can lead to excessive internal rotation and result in knee pain.
What is the origin insertion and action of the tensor fasciae latae?
Origin, Insertion and Nerve Supply The TFL descends on the anterolateral aspect over the thigh, running superficially to the greater trochanter of the femur. It inserts distally to the IT track/band, which is comprised of the fascial aponeurosis of the gluteus maximus and the tensor fascia latae.
Is TFL same as hip flexor?
The TFL is a hip flexor, abductor and internal rotator. It works in conjunction with the gluteus medius and gluteus maximus to stabilise the leg during the stance phase of walking and running. The TFL anteriorly rotates your pelvis.

What is the function of the Tensor Fasciae Latae?
The main task of the tensor fasciae latae is to sustain tension of the iliotibial tract. As the femoral shaft meets the pelvis, an angled pressure from above imposes a high bending strain to the femur. Both the hip abductors and the tensor fasciae latae counteract the pressure on the opposite side and help stabilize the bone (tension banding effect). Furthermore, the activation of the muscle leads to an abduction, flexion and internal rotation of the hip joint.

Where is the descending muscle located?
While descending down the thigh, the muscle is found between the two layers of fascia lata. Due to its superficial position, this muscle is easily palpated. This is usually performed at the area located halfway between the anterior superior iliac spine and the greater trochanter of femur.
What is the function of the tensor fasciae latae?
The tensor fasciae latae is a tensor of the fascia lata; continuing its action, the oblique direction of its fibers enables it to stabilize the hip in extension (assists gluteus maximus during hip extension).
Where is the Tensor Fasciae Latae?
It is inserted between the two layers of the iliotibial tract of the fascia lata about the junction of the middle and upper thirds of the thigh. The tensor fasciae latae tautens the iliotibial tract and braces the knee, especially when the opposite foot is lifted. The terminal insertion point lies on the lateral condyle of the tibia.
What muscle is used to stretch the tensor fasciae latae?
The TFL is a hip abductor muscle. To stretch the tensor fasciae latae, the knee may be brought medially across the body (adducted). If one leans against a wall with crossed legs (externally/laterally rotated hips) and pushes the pelvis away from the wall (leaning the upper body towards it) sidebending the lumbar spine (i.e.: curving the spine to the side) should be avoided as it stretches the lumbar region rather than the tensor fasciae latae and other muscles which cross the hip rather than the spine.

Tensor fasciae latae is innervated by the superior gluteal nerve, L5 and S1. At its origins of the anterior rami of L4, L5, and S1 nerves, the superior gluteal nerve exits the pelvis via greater sciatic foramen superior to the piriformis. The nerve also courses between the gluteus medius and minimus. The superior gluteal artery also supplies the ...
Why is the TFL tight?

What is the TFL muscle?
Tensor Fasciae Lata: The tensor fasciae lata (TFL) is a small superficial muscle of the thigh which lies towards the anterior edge of the iliac crest. It is related to the gluteus maximus in function and structure and is continuous with the iliotibial tract, which attaches to the tibia. The muscle assists in maintaining the balance of the pelvis while running, standing, or walking.
Which muscle is used to help with walking?
Tensor fasciae latae muscle assist in walking by inferiorly tilting the ilium on the weight-bearing side, with the result an upward tilt of the contralateral of the hip. Thus, allowing the leg of the non-weight bearing hip to swing through without hitting the ground throughout the swing phase of the gait.

Overview
The tensor fasciae latae (or tensor fasciæ latæ or, formerly, tensor vaginae femoris) is a muscle of the thigh. Together with the gluteus maximus, it acts on the iliotibial band and is continuous with the iliotibial tract, which attaches to the tibia. The muscle assists in keeping the balance of the pelvis while standing, walking, or running.
Function
The tensor fasciae latae is a tensor of the fascia lata; continuing its action, the oblique direction of its fibers enables it to stabilize the hip in extension (assists gluteus maximus during hip extension). The fascia lata is a fibrous sheath that encircles the thigh like a subcutaneous stocking and tightly binds its muscles. On the lateral surface, it combines with the tendons of the gluteus maximus and tensor fasciae latae to form the iliotibial tract, which extends from the ilia…
Structure
It arises from the anterior part of the outer lip of the iliac crest; from the outer surface of the anterior superior iliac spine, and part of the outer border of the notch below it, between the gluteus medius and sartorius; and from the deep surface of the fascia lata.
It is inserted between the two layers of the iliotibial tract of the fascia lata about the junction of the middle and upper thirds of the thigh. The tensor fasciae latae tautens the iliotibial tract and brac…
Clinical significance
Because it is used for so many movements and is in a shortened position when seated, the TFL becomes tight easily. TFL stretches lengthen this important muscle.
A small case notes that “it seems possible that a sloped or banked surface could predispose an individual to a TFL strain.” In such a case, “treatment usually consists of rest, heat, and flexibility exercises”, such as lliotibial band stretching.
Etymology
"Tensor fasciae latae" translates from Latin to English as "stretcher of the side band". "Tensor" is an agent noun that comes from the past participle stem "tens-" of the Latin verb "tendere", meaning "to stretch". "Fasciae" is the Latin term for "of the band" and is in the singular genitive case. "Latae" is the respective singular, genitive, feminine form of the Latin adjective "latus" meaning "side".
