During scoliosis screening for school-age children, which position is used to assess curvature?

• A. Bending forward with back parallel to the floor
• B. Standing erect
• C. Lying on the back with knees extended
• D. Sitting upright with arms overhead

Answer: (A)

The main concept is that scoliosis screening uses a forward-bend position to reveal curvature. Bending forward with the back parallel to the floor—the Adams forward bend test—accentuates the spinal rotation and rib prominence that accompany scoliosis. When the spine curves laterally and rotates, bending forward makes the rib hump on the convex side more noticeable and creates visible asymmetry in the trunk, shoulders, or hips. This quick, noninvasive position helps clinicians detect abnormalities that may not be evident when standing straight or lying down. Standing erect or lying on the back, or sitting with arms overhead, typically do not expose the rib hump as clearly, so they’re less effective for screening.
