AbstractAbstract
This was an experimental and comparative study done to see the effect of L5 – S1 disc herniation on MNCV, its latency difference and H reflex latency and to prove the efficacy of electrodiagnosis as a reliable tool to assess the S1 radiculopathy due to disc herniation. MNCV, its latency difference and H reflex latency was compared between affected and unaffected sides of 12 symptomatic and MRI diagnosed subjects. Affected side data was also compared with normative data. CONCLUSION: MNCV and H latency showed significant changes between affected and unaffected sides but M latency presented insignificant results. Comparison of data with normative data also showed significant changes, thus proving electrodiagnosis as a reliable adjunct to MRI.
