Diagnostic value of different electrophysiologic tests in cervical disk prolapse.
1988
We evaluated 24 patients with radiologically verified cervical disk prolapse. EMG abnormalities appeared in 67% of cases studied; dermatomal somatosensory evoked potentials revealed 85% abnormal findings on the affected side, but also revealed abnormalities in adjacent segments. In 38%, F responses were abnormal. We found electrodiagnostic abnormalities at levels without a disk prolapse, probably due to degenerative spondylopathic changes and beginning consecutive vascular compromise.
