An impingement in the lower back or lumbar-sacral spine can be manifested with symptoms and pain followed by radiation in a dermatomal pattern in the foot known as Lumbosacral radiculopathy. The purpose of present study was to assess diagnostic utility of H-reflex in patients of Lumbosacral radiculopathy. A randomized paired-study design was utilized to evaluate H-reflex elicited with tibial nerve stimulation. Thirty five patients with unilateral Lumbar radiculopathy, confirmed by clinical and magnetic resonance imaging (MRI) evidences were studied. Selected patients were divided in two groups GROUP A- Asymptomatic side in subject clinically diagnosed with radiculitis/radiculopathy is used as control group. GROUP B- Symptomatic side in same subjects clinically diagnosed with radiculitis/radiculopathy used as case group. A high-voltage electrical stimulator was used to elicit H-reflex bilaterally at the popliteal fossa for the diagnosis of first Lumbosacral (LS1) nerve-root radiculopathy. The variation in side to side H- latency and H/H-amplitude ratio by non-invasive technique brings awareness to clinicians about the Lumbosacral radiculopathy and this report may also be useful to clinician for early diagnosis of Lumbosacral radiculopathy.
