WebJan 1, 2013 · Myokymic discharges refer to the underlying electrophysiological abnormality in both clinical myokymia and neuromyotonia. The discharges are single motor unit action potentials which fire at rates of 5–150 Hz in bursts (Fig. 70.1). They may be doublets, triplets, or multiplets, firing at regular or slightly irregular intervals. WebClinical findings include cramps, fasciculations, and myokymia. Electrodiagnosis plays a key role in diagnosis by demonstrating after-discharges on nerve conduction studies, and fasciculation potentials, myokymic discharges, neuromyotonic discharges, and other types of abnormal spontaneous activity on needle examination.
