A significant increase in muscle fatty infiltration and cross-sectional area (CSA) asymmetry at the level below the compression was observed in patients with Degenerative Cervical Myelopathy (DCM). Results also suggest an association between cervical muscle morphology and DCM clinical symptoms and functional status 1).
Preoperative sensory-evoked potentials may be considered for patients in whom clinical factors do not provide clear guidance if such information would potentially change therapeutic decisions 2).
Results suggest that Motor evoked potentials (MEPs), peripheral conduction time (PCT), and central motor conduction time (CMCT) parameters each reveal abnormalities in the upper and lower motor neurons even in patients with diabetes mellitus (DM). The results also show a prolonged PCT in compressive cervical myelopathy (CCM)-DM patients, despite having no history of diabetic neuropathy. Corticospinal tract impairments are similar between CCM and CCM-DM patients, while the JOA score of the CCM-DM patients is lower than that in the CCM patients. The JOA score in CCM-DM patients may be influenced by additional impairments in peripheral nerves or other diabetic complications. These electrophysiological studies may be useful for screening motor pathway function for CCM in patients with DM 3).
