- Alternative Title
- A Clinical Study comparing the findings of MRI and EMG in low back pain patients
- Abstract
- The 80% of the general population experience low back pain once in a life. The causes of the low back pain are variable and the herniated nucleus pulposus(HNP) is one of common cause. Recently the usage of MRI in diagnosing the HNP and evaluating it's severity is increasing, but the EMG is still necessary to find the deficit of the involved root functionally. We compared the findings of MRI and EMG from the 87 patients with the low back pain from May 1990 to October 1992. The results were as follows :
1) Disease distribution on MRI was HNP 59 cases, spinal stenosis 8 cases, Tuberculous spondylitis 4 cases, degenerative change 2 cases, metastatic tumor 1 case, and 13 cases were normal.
2) The severity of HNP was classified on the MRI findings, according to Masaryk, bulging 19 cases, protrusion 17 cases, extrusion 16 cases, sequestration 7 cases.
3) Fifty-five of the 59 cases of HNP were diagnosed radiculopathy by needle EMG and 40 cases showed abnormal conduction studies.(motor nerve conduction or H-reflex)
4) There is no significant correlation between the severity of lesion on MRI and abnormal spontaneous activities on needle EMG in 46 cases of HNP-symptomatic duration more than 2 weeks.
