STUDY DESIGN A total of 15 patients with lumbar disc herniation at the L5-S1 disc level who underwent microendoscopic discectomy were examined. The nerve root blood flow and electrophysiological values were measured during an intraoperative straight-leg-raising (SLR) test. OBJECTIVE To investigate the relationships between nerve root blood flow changes and the electrophysiological values duri...

The straight-leg-raising (SLR) test is one of the most significant signs for making a clinical diagnosis of lumbar disc herniation [1].
