•Chorea is a hyperkinetic movement disorder characterized by rapid and unpredictable contractions affecting mostly distal limbs, but also the face and trunk.

•The movements are involuntary and nonpatterned with variable speed, timing, and direction, flowing from one body part to another and giving, in less severe cases, an appearance of fidgetiness.

•The unpredictable nature of chorea is a feature that distinguishes it from tremor and dystonia
