What is the purpose of using a scoliometer in scoliosis screening?

• A. To measure abnormal degrees of lateral spinal curvature
• B. To take radiographs
• C. To assess spinal flexibility
• D. To evaluate rib tenderness

Answer: (A)

A scoliometer measures the angle of trunk rotation during scoliosis screening. In practice, the clinician performs the forward-bend test and places the device over the spine at the point of highest rotation. The reading, in degrees, indicates how much the trunk is rotated to one side; larger readings suggest a higher likelihood of a spinal curvature and help determine whether radiographs are needed for confirmation. It isn’t used to take X-rays, nor is it primarily used to assess spinal flexibility or rib tenderness—those require other tests. So, the scoliometer serves as a quick, noninvasive way to flag potential scoliosis by quantifying rotation that accompanies lateral curvature.
