Lumbar radiculopathy is a condition in which pain is caused over lower back and hip radiating to the back of the thigh and leg. In this study, 30 patients with subacute lumbar radiculopathy with age group 30–60 years were selected. All the participants received active sciatic nerve mobilization (ANM) for 6 days in 1 week along with conventional physiotherapy. The purpose was to find out the effect of active neural mobilization on H–reflex latency in patients with subacute lumbar radiculopathy. The result showed that neural mobilization in addition to conventional physiotherapy treatment is effective in reduction of H–reflex latency in patients with subacute Lumbar radiculopathy.
