Motor evoked potentials and magnetic resonance imaging for cervical myelopathy

The purpose of this study is to elucidate the usefulness of the motor evoked potentials (MEPs) and MRI for the prognostication of the treatment for cervical spondylosis patients. Retrospectively we have studied the MEPs and the MRI image of 71 patients of cervical myelopathy. Before the treatment, the patients had the remarkable prolonged central motor conduction time. MRIs indicated the deformed spinal cord and the signal intensity of the involved spinal cord in T2 image was remarkably high, The recovery rate of JOA score was correlated with the central motor conduction time and the signal intensity ratio in the involved area.
