STUDY ON CLINICAL FEATUTES, MRI AND NERVE CONDUCTION IN PATIENT WITH LUMBAR DISC HERNIATION

Objective: Lumbar disc herniation is a common disease that affects the quality of life of patients. The study aimed to assess the severity of the disc herniation on magnetic resonance imaging and neurological conduction disorder on Electromyogramme (EMG). Methods: Cross-sectional studies included 40 patients who were diagnosed lumbar disc herniation by clinical features and magnetic resonance imaging in Thua thien Hue Rehabilitation hospital from January 2016 to Dec 2016. Results: Clinical Features: The rate of Lombalgia was 85%, Schober score (+) was 60%, limitation of lumber movement was 65%. There were 45% patients having 2 sites of disc herniation on lumber MRI. Motor conduction velocity of posterior tibia nerve and deep febularis nerve in the side with disc herniation were 43.62 ± 7.53 ms and 45.99±5.74 ms consecutively lower than those in the side without disc herniation. F wave frequence of posterior tibia nerve and deep febularis nerve in the side with disc herniation were 32.63±14.05% and 29.82±12.29% consecutively lower than those in the side without disc herniation. Conclusion: there was a relationship between clinical features, lumbar MRI and change of nerve conductions on EMG in patients with lumbar disc herniation Key words: disc herniation, MRI, EMG, lombalgia
