TFL – TENSOR FASCIA LATAE
- PRIMARY FUNCTION
– Hip Internal Rotation - SECONDARY FUNCTION
– Serves as an accessory muscle/ hip synergist in Hip Abduction and Hip Flexion
– Together with gluteus maximus and the ITB, it stabilizes the hip joint by holding the head of the femur in the acetabulum
– Together with the gluteus maximus it contributes in stability of the knee during extension and also in partial flexion
– As part of the iliotibial tract it aids lateral rotation of the leg
– Assists in walking by inferiorly tilting the ilium on the weight-bearing side, with resulting in an upward tilt of the contralateral hip. Thus, allowing the leg of the non weight bearing hip to swing through without hitting the ground during the swing phase of the gait – Physiopedia
ITB
– Assists with Hip Abduction and Internal Rotation; plays a supportive role in the gait cycle
– Physiopedia
– The actions of the muscles associated with the ITB are the TFL and some fibers of Gluteus Maximus
– Hip Flexion, Hip Extension, Hip Abduction, Hip External Rotation, Hip Internal Rotation
– The ITB contributes to lateral knee stabilization
