Temporal Alterations in Somatosensory Evoked Potentials in Cervical Spondylotic Myelopathy

Abstract

Although a large body of literature exists regarding acute spinal cord trauma, few studies have been devoted to the natural course of the “progressive” myelopathies. The majority of such studies concentrate on cervical spondylotic myelopathy (CSM) and direct attention mainly at the diagnostic criteria and effects of surgical intervention [9, 10]. The paucity of information is understandable considering the immense difficulty in designing a chronic animal preparation to mimic the clinical situation with the timing and character of the compression in the laboratory animals. These limitations suggest that longitudinal clinical studies with associated neurophysiologic observations offer a fruitful method to evaluate the natural history of this disease entity.
