Definition of Myoclonic twitch
Myoclonic twitch: A rapid, involuntary muscle contraction, particularly near the eye. Myoclonic twitches resemble and may be mistaken for tics. Like tics, they tend to occur more often when the person is under stress; unlike tics, they are not preceded by any sensation and they cannot be delayed.Source: MedTerms™ Medical Dictionary
