In the straight-leg raise test, which finding constitutes a positive result?

Explanation:
The straight-leg raise tests for irritation of the sciatic nerve roots by placing tension on the neural structures in the lower spine. A positive result is when lifting the leg reproduces symptoms that travel down the leg, typically below the knee, consistent with radicular pain from nerve root irritation (often due to lumbar disc herniation). Pain confined to the back or only at the knee does not indicate nerve root involvement, and no symptoms means the test is negative. So reproducing leg symptoms with the maneuver best indicates a radiculopathy rather than a local joint or soft-tissue issue.
