Hip internal rotators move the contralateral side of the pelvis forward in the horizontal plane to assist with what during gait?

• A. Advancing the swing limb
• B. Heel rocker control only
• C. Toe extension only
• D. Knee extension only

Answer: (A)

Gait relies on rotation of the pelvis in the transverse plane to help move the leg forward. When the hip on the stance side internally rotates, it drives the opposite side of the pelvis ahead in the horizontal plane, aiding the forward progression of the swing limb. This pelvic movement specifically supports advancing the swinging leg, rather than the other aspects like heel rocker control, toe extension, or knee extension, which involve different joints and phases of gait.
