Rotation of the horse's pelvis results in which pelvic adjustment in the rider?

• A. Pelvic rotation
• B. Posterior pelvic tilt
• C. Anterior pelvic tilt
• D. Pelvic lateral tilt

Answer: (D)

When the horse’s pelvis rotates during gait, the rider’s pelvis tends to tilt side-to-side to absorb and follow that motion. This results in a lateral tilt in the rider’s pelvis, rather than twisting around the body's vertical axis or tilting forward or backward. Pelvic rotation is a twisting movement in the transverse plane, while anterior or posterior tilt occurs in the sagittal plane. The horse’s pelvic rotation mainly drives a coronal-plane adjustment in the rider, which is why pelvic lateral tilt is the best description of the rider’s response.
