Myokymia (Myoclonus Mimic)
A 23-year-old woman with lupus who has experienced finger shakes since the age of 16. These difficult-to-characterize, tremulous movements (of lower amplitude than, and not as fast as, myoclonus), were ultimately categorized as neuromyotonia or electric myokymia, a peripheral nerve hyperexcitability disorder.
