If an individual has a weak gluteus medius:

a. The hip joint compression forces are greater during single limb stance, which can lead to joint degeneration.
b. He or she will rarely present with a Trendelenburg gait.
c. He or she will often shift the trunk over the hip to eliminate the force the gluteus medius needs to produce for single limb stance.
d. Using a cane on the ipsilateral side is a good way to address the weakness.

ANS: D
Gravitational torque at the pelvis is the product of body weight and the distance that the line of gravity (LoG) lies from the hip joint axis (moment arm). If there is a need to reduce the torque of gravity in unilateral stance and if body weight cannot be reduced, the MA of the gravitational force can be reduced by laterally leaning the trunk over the pelvis toward the side of pain or weakness during unilateral stance on the side of the painful limb.
