Sitting slumped with a rounded back in a chair would result in what kind of tilt to the pelvis?

• A. Anterior
• B. Posterior
• C. Lateral
• D. Superior

Answer: (B)

Posture in a chair directly affects the pelvis. When you sit with a rounded upper back and the lower back flattening, the spine flexes forward and the pelvis rotates backward to balance the body. This backward rotation is a posterior pelvic tilt, and it also reduces the natural inward curve of the lower back. An anterior tilt would happen if the pelvis rotated forward and increased the lumbar curve, which isn’t what slumping does. A lateral tilt would involve a tilt from one side to the other, and a superior tilt would involve a tilt upward, neither of which describes a forward-rounded sitting posture.
