Eksempler på gluteus

• When gluteus maximus is weak, trunk lurches backward (gluteus maximus lurch) at heel-strike on weakened side to interrupt forward motion of the trunk.

• The gluteus maximus is also a strong hip stabilzer.

• At the lower border of the piriformis muscle, the nerve turns backward and divides into upward and downward diverging branches, which enter the gluteus maximus.

• Surprisingly, however, the gluteus maximus is not important posturally, is relaxed when one is standing, and is little used in walking.

• Attached to the posterior side is gluteus maximus which extend the thigh during ambulation.

• The gluteus medius is very important during the stance phase of the gait cycle to maintain both hips at the same level.

• Hip abduction is performed primarily by the hip abductors (gluteus medius and minimus).

• Additionally, with the hip flexed the gluteus medius and minimus internally rotate the thigh.

• The posterior fibres of gluteus medius contract to produce hip extension, lateral rotation and abduction.

• In addition to this, the relatively wide shape (front to back) of the pelvis provides greater leverage for the gluteus medius and minimus.

• The tensor fasciae latae works in synergy with the gluteus medius and gluteus minimus muscles to abduct and medially rotate the femur.

• A great exercise to strengthen the gluteus is the side lying hip abduction.

• It pierces the lower part of the sacrotuberous ligament, and winds around the inferior border of the gluteus maximus.

• Results showed significant increases in activation of tibialis anterior, gastrocnemius, soleus, rectus femoris, vastus lateralis, medial hamstring, biceps femoris, and gluteus maximus before foot strike.

• This will result in maximal stimulation of the gluteus maximus musculature when using electrical stimulation for the purpose of prevention of pressure ulcers.
