Tic

A tic is a sudden, repetitive, nonrhythmic motor movement or vocalization involving discrete muscle groups. Tics can be invisible to the observer, such as abdominal tensing or toe crunching. Common motor and phonic tics are, respectively, eye blinking and throat clearing.

Tics must be distinguished from movements of other movement disorders such as chorea, dystonia, myoclonus; movements exhibited in stereotypic movement disorder or some people with autism; and the compulsions of obsessive-compulsive disorder (OCD) and seizure activity.

Famous quotes containing the word tic:

    Experiment is necessary in establishing an academy, but certain principles must apply to this business of art as to any other business which affects the artis tic sense of the community. Great art speaks a language which every intelligent person can understand. The people who call themselves modernists today speak a different language.
    Robert Menzies (1894–1978)
