The shoulder girdle rotates in what direction relative to the pelvis?

• A. Opposite of the pelvis
• B. Same direction as the pelvis only
• C. No rotation occurs
• D. Only toward the stance limb

Answer: (A)

The shoulder girdle rotates opposite to the pelvis. In gait and coordinated movement, the pelvis turns in one direction while the shoulder girdle turns the other way, helping keep the trunk stable and allowing smooth arm swing without twisting the torso excessively. This reciprocal, opposite rotation maintains balance and efficient movement, so the shoulder girdle is not rotating in the same direction as the pelvis, nor is it motionless.
