Which statement about the DS stands true?

• A. DS stands on the side opposite the lateral bend
• B. DS stands on the side of the patient that is lateral bending
• C. DS is the stabilization point
• D. DS is the contact hand

Answer: (B)

When assessing lateral bending, the driving (DS) hand belongs on the side of the bend. Placing the DS on the same side as the lateral bend lets your hand move with the curve, directly sensing the segmental motion, subtle rotations, and changes in stiffness as the spine flexes sideways. This position provides the most accurate sense of how the vertebrae are moving together and where any abnormal motion or asymmetry lies. Putting the DS on the opposite side would distance your sensing from the actual motion and reduce sensitivity. Treating the DS as the stabilization point or as the contact hand would mischaracterize its role and hinder your ability to detect the bend-driven changes. So, the DS should be on the side of the lateral bend.
