Adams forward bend test for scoliosis

The Adams forward bend test demonstrates the rotational component of scoliosis. It is performed by observing the patient from the back while they bend forward at the waist until the spine becomes parallel to the horizontal plane. The patient's feet should be together, knees straight ahead, and arms hanging free. Asymmetry of the upper thoracic, midthoracic, thoracolumbar, or lumbar region is noted. Panel A depicts the right rib hump of thoracic scoliosis. Panel B depicts normal spinal curvature.
