Cervical paraspinal muscle abnormalities and symptom duration: A multivariate analysis
Abstract
The purpose of this study was to determine whether paraspinal and other major proximal and distal muscle spontaneous activity (SA) is related to cervical radiculopathy (CR) symptom duration. A multivariate analysis of 124 (retrospectively identified) electrodiagnostically confirmed CRs was used to test these hypotheses. The results showed no evidence of correlation between SA and symptom duration for any of the upper limb muscles analyzed. © 1998 John Wiley & Sons, Inc. Muscle Nerve 21:640–642, 1998.
