GLUTEUS MAXIMUS


1


  1. PRIMARY FUNCTION
    · Hip Extension
    ·
    Hip External Rotation
  2. ASSISTING
    · Upper Fibers Hip Abduction
    · Lower Fibers Hip Adduction
    · Hip Extension of the trunk from a flexed position
  3. NOTES
    · As a powerful extensor of the hip joint, it is suited for step-ups, climbing or running but is not used greatly during normal walking – Physiopedia

GLUTEUS MEDIUS | GLUTEUS MINIMUS


1


  1. GLUTEUS MEDIUS
    – Hip Ab·duction
    – Anterior Fibers: Flexion & Internal Rotation
    – Posterior Fibers: Extension & External Rotation
    – When hip is flexed all fibers Internally Rotate the hip
  2. GLUTEUS MINIMUS
    – Hip Ab·duction
    – Anterior Fibers: Internal Rotation
    – When hip is flexed all fibers Internally Rotate the hip
  3. OTHER NOTES
    – Levels & Stabilizes Hips 

TFL


1


Physiopedia
– Prime mover in Hip Internal Rotation and a weak Hip Abductor
– 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


ITB


1


– 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


SARTORIUS


1


  1. PRIMARY FUNCTION of the SARTORIUS
    · Hip Flexion
  2. ASSISTING FUNCTION of the TFL
    · Hip Ab·duction
    · Hip External Rotation
    · Knee Internal Rotation when Knee is Flexed
