The Kemp Test is used to assess which condition?

• A. Facet joint syndrome
• B. Hamstring strain
• C. Nerve root compression syndrome
• D. Sacroiliac joint dysfunction

Answer: (C)

Kemp test loads the lumbar spine in a way that tightens the neural foramina and tensions the exiting nerve roots, so it is used to detect nerve root compression or irritation. During the maneuver, the clinician extends the trunk while rotating and side-bending toward the side of concern, which narrows the foraminal space and increases stress on the nerve roots. If a compressed or irritated nerve root is present, this loading often reproduces radicular symptoms—pain that travels down the leg, sometimes with numbness or weakness in a dermatomal pattern. When the pain remains localized to the back with no leg radiation, facet-related pain is more likely. Because the test can be influenced by multiple structures, it’s most informative when interpreted alongside other findings and tests.
