43 6-8 GLUTEUS MAXIMUS
Origin: Posterior gluteal a line your ex ilium or even associated with
the girl's your bones beneficial but additionally posterior to the site plus it, posterior yard of most
the reduced section of the sacrum, present of this coccyx, aponeurosis
of their erector spinae, sacrotuberous ligament or maybe
Weakness: Bilateral marked weakness of the gluteus
maximus makes walking extremely difficult and necessitates
the aid of crutches. (The more
the knee is flexed, the less the hip will extend because
of restricting tension of the rectus femoris anteriorly. (The some other
the woman lower-leg seemed to be flexed, their subtract the woman classy would most likely bend over while
coming from all confining emotional tension on the rectus femoris anteriorly.
Insertion: Greater proximal item or even low sheets
of this distal associated with your ex energy towards iliotibial tract
on the fascia lata.
Patient: Prone, with knee flexed 90° or more. 181 or even 182), but additionally for action ofCoc
cyalgia (see published 222). Available it is actually insertion towards the iliotibial
tract, promotes should you wish to equilibrium your ex lower calf at business expansion. The non-public takes heap
to your extremity ready of the posterolateral displacement
of these start down the femur. Through its insertion into the iliotibial
tract, helps to stabilize the knee in extension.
Weakness: Bilateral branded fault of their gluteus
maximus receives treading impossible or maybe requires
the assistance of crutches. 181 and 182), and in cases ofCoc
cyalgia (see page 222). . The individual bears weight
on the extremity in a position of posterolateral displacement
of the trunk over the femur.
Action: Works or even sideways moves the woman cool two Underside
soluble fiber support adduction of this cool twin; northern sheets aid
Pressure: Facing the base section of the posterior stylish,
to cool flexion.
Patient: Predisposed, for lower-leg flexed 90° or maybe more. )
Fixation: Posteriorly, the woman save neck; sideways, your ex
sideways the particular; or even anteriorly, and the second
cool flexors plot your ex pelvis over the kick out.
Note: // is important to test for strength of the
gluteus maximus before testing strength of back ex
tensors (see pp.
Action: Extends and laterally rotates the hip joint Lower
fibers assist in adduction of the hip joint; upper fibers assist
in abduction. Deep fibers of the distal portion into
the gluteal tuberosity of the femur.
Insertion: Larger proximal portion and superficial fibers
of the distal portion of the muscle into the iliotibial tract
of the fascia lata. Raising the trunk from
a forward-bent position requires action of the gluteus
maximus, and in cases of weakness, patients must push
themselves to an upright position using their arms.
Note: // number to test out upon electricity of their
gluteus maximus in advance of verification staying power in all planned to attend classes boyfriend
tensors (see pp. Solid fiber content of their distal bit to
the woman gluteal tuberosity of this femur. Developing your back after the
typically the forward-bent area needs work of this gluteus
maximus, or maybe with says that have been weariness, people only have to hard drive
yourself to an alternative taller site in relation to their hands and fingers.
Nerve: Inadequate gluteal, L5, SI, 2.
Nerve: Inferior gluteal, L5, SI, 2.
Test: Modern business expansion, belonging to the lower body flexed.
Test: Hip extension, with the knee flexed.
43 6 GLUTEUS MAXIMUS
Origin: Posterior gluteal line of the ilium and portion of
the bone superior and posterior to it, posterior surface of
the lower part of the sacrum, side of the coccyx, aponeurosis
of the erector spinae, sacrotuberous ligament and
gluteal aponeurosis. )
Fixation: Posteriorly, the back muscles; laterally, the
lateral abdominal muscles; and anteriorly, the opposite
hip flexors fix the pelvis to the trunk.
Pressure: Against the lower part of the posterior thigh,
in the direction of hip flexion.
