Keywords: | herniated disc induced cervical myelopathy;motor evoked potential;spinal cord motor conduction velocity;surgery | Issue Date: | 1999 | Journal Volume: | v.22 | Journal Issue: | n.2-3 | Start page/Pages: | 107-111 | Source: | NEUROSURGICAL REVIEW | Abstract: | A motor evoked potential (MEP) study with percutaneous A motor evoked potential (MEP) study with percutaneous magnetic stimulation over the motor cortices and an F-wave magnetic stimulation over the motor cortices and an F-wave study in peripheral nerves were performed to measure spinal study in peripheral nerves were performed to measure spinal cord motor conduction velocity (SCMCV) in 25 patients with cord motor conduction velocity (SCMCV) in 25 patients with herniated disc induced cervical myelopathy (HDICM). Grading herniated disc-induced cervical myelopathy ( HDICM). Grading of motor function and assessment of SCMCV were performed of motor function and assessment of SCMCV were performed before and 2 years after microsurgical discectomy. The before and 2 years after microsurgical discectomy. The results show that functional motor improvement accompanied results show that functional motor improvement accompanied by an increase in SCMCV occurred in grade I patients with by an increase in SCMCV occurred in grade I patients with mild neurological impairment after surgery, whereas no mild neurological impairment after surgery, whereas no definite change was seen in grade II and grade III patients definite change was seen in grade II and grade III patients with moderate and severely neurological impairment. This with moderate and severely neurological impairment. This finding suggests that measurement of SCMCV by MEP study with finding suggests that measurement of SCMCV by MEP study with a noninvasive method may provide an objective and a noninvasive method may provide an objective and quantitative method to assessment of the functional quantitative method to assessment of the functional integrity of the spinal motor pathway and that the results integrity of the spinal motor pathway and that the results of such studies may serve as a predictor in evaluation of of such studies may serve as a predictor in evaluation of surgical outcome in patients with HDICM. surgical outcome in patients with HDICM. |
