What does a positive straight leg test feel like?

A positive test elicits pain in the leg, buttock, or back at 60 degrees or less of leg elevation.

Is the straight leg raise test valid for sciatic pain?

What is the history of the leg raising test?

HISTORICAL NOTE In 1881, J. J. Forst described a test to provoke pain in patients with sciatica. The involved lower extremity of a supine patient is raised with the knee extended.
