Nerve Conduction Studies in Patients with LumbosacralRadiculopathy Caused by Lumbar Intervertebral Disc Herniation

Nerve conduction studies (NCS) are electrodiagnostic tests used to evaluate peripheral nerves functions and aid inthe assessment of patients with neuromuscular complaints. (ere is contrasting evidence concerning the use of NCS in theassessment of patients with lumbosacral radiculopathy.Objectives. (is study was conducted to evaluate nerve conduction studiesabnormalities in patients with lumbosacral radiculopathy and to find out their relation to abnormal physical examination findings.Materials and Methods. Twenty-seven patients with lumbosacral radiculopathy caused by L4/5 or L5/S1 intervertebral discprolapse confirmed by magnetic resonance imaging (MRI) were recruited in the study. Twenty-five healthy subjects matched inage and sex served as control. Motor nerve conduction study bilaterally for both common peroneal and tibial nerves, F-wave forboth nerves, and H-reflex had been conducted.Results. No significant difference was found in the motor nerve conduction studyparameters (latency, amplitude, and conduction velocity) between the patients group and the control group. (ere was significantprolongation in H-reflex latency of both symptomatic and asymptomatic side in the patients group compared to the control group(P<0.05). Also, F-wave latencies (F minimum, F maximum, and F mean) of the tibial nerve were significantly prolonged(P<0.05) compared to control.Conclusion. Prolonged H-reflex latency was the commonest encountered abnormality in our studyfollowed by F-wave latencies of the tibial nerve
