Which tool is used to measure abnormal degrees of lateral spinal curvature during scoliosis screening?

• A. X-ray
• B. Tape measure
• C. Scoliometer
• D. Ruler

Answer: (C)

In scoliosis screening, the key idea is to quickly detect abnormal trunk rotation that accompanies a lateral curvature. The tool used for this fast assessment is the scoliometer. During the forward-bend test, the clinician places the scoliometer over the spine and reads the angle of trunk rotation in degrees. A higher reading indicates a greater likelihood of scoliosis and helps decide whether an X-ray is needed to measure the actual curve (Cobb angle). An X-ray is used for precise measurement of curvature, but the scoliometer provides a simple, noninvasive screening measure of rotation. Tape measures or rulers aren’t reliable for assessing trunk rotation or scoliosis in this screening context.
