Choreiform movements are abrupt, irregular, and purposeless. They are quite brief, asymmetric, present at rest, and may persist during sleep. The term chorea is derived from the Greek word for dancing and was applied initially to epidemics of dancing mania in the Middle Ages, in which large numbers of people danced together for days.
