EMG in Syringomyelia
Source: Nogues MA, Stalberg E. Electrodiagnostic findings in syringomyelia. Muscle Nerve 1999;22:1653-1659.
The electrodiagnostic distinction of syrinx from motor neuron disease may be impossible. Fibrillation potentials in atrophic arm muscles with sparing of leg muscles is more likely in the former, but both demonstrate normal sensory nerve conduction studies, depressed motor amplitudes, and normal motor conduction velocities. Using multichannel surface EMG recording, as well as routine needle EMG, unique forms of spontaneous activity may be documented in syringomyelia. Among 43 such patients, 10 ...
