Pattern of segmental motor involvement in syringomyelia: a single fibre EMG study. 1980

M S Schwartz, and E Stålberg, and M Swash

Single fibre EMG has been used to study the pattern of upper limb motor involvement in syringomyelia. Biceps brachii, extensor digitorum communis (EDC) and first dorsal interosseous muscles (1stDI) representing C5/6, C7/8 and C8/T1 segments, were studied. In the biceps the fibre density was slightly increased in most patients, in EDC it was about twice the normal and in the 1stDI it was about three times normal. The potentials were least stable and of longest duration in the 1stDI. These findings seem to indicate a relatively constant pattern of involvement of anterior horn cells in the brachial segments in syringomyelia.

D008475	Median Nerve	A major nerve of the upper extremity. In humans, the fibers of the median nerve originate in the lower cervical and upper thoracic spinal cord (usually C6 to T1), travel via the brachial plexus, and supply sensory and motor innervation to parts of the forearm and hand.

D005071	Evoked Potentials	Electrical responses recorded from nerve, muscle, SENSORY RECEPTOR, or area of the CENTRAL NERVOUS SYSTEM following stimulation. They range from less than a microvolt to several microvolts. The evoked potential can be auditory (EVOKED POTENTIALS, AUDITORY), somatosensory (EVOKED POTENTIALS, SOMATOSENSORY), visual (EVOKED POTENTIALS, VISUAL), or motor (EVOKED POTENTIALS, MOTOR), or other modalities that have been reported.
