A cervical distraction test that improves symptoms is used to confirm nerve root compression. Which option best describes this?

• A. Confirms nerve root compression
• B. Confirms no nerve pathology
• C. Indicates facet joint arthritis
• D. Indicates muscular strain

Answer: (A)

Relief of symptoms with cervical traction indicates that the pain is coming from nerve tissue being pressed in the cervical spine. When you distract the neck, the openings where the nerve roots exit (the foramina) widen, decreasing pressure on the affected nerve root. If radicular (nerve root) symptoms improve with this maneuver, it supports nerve root compression as the source, such as from a disc herniation or foraminal stenosis. This test is not meant to prove there is no nerve pathology or to diagnose solely facet joint arthritis or a muscular strain—those conditions don’t specifically rely on decompression of the nerve roots for their pain pattern, and the distraction maneuver doesn’t provide a definitive diagnosis by itself. A positive result helps identify radiculopathy, but imaging and other exam findings are still needed to localize and confirm the pathology.
