Abstract

Recordings of electrical activity from muscles provides the best means of studying motor control. Quantitation of surface electromyograms (SEMGs) is problematic due to the ill-posed nature of the inverse problem. As a first step towards establishing methods for comparing across muscles and across subjects, the authors examined the repeatability of activity recorded during a comprehensive protocol. To facilitate overview of the protocol, a motor control profile was developed. Results from comparisons in 50 spinal cord injured subjects are presented
