Chorea is a movement disorder that results from the continuous and random flow of muscle contractions leading to a dance‐like appearance. The aims of this article are to define chorea, discuss its underlying causes, and provide a video demonstration of a seven‐step guide on how to examine a patient with this movement disorder. This guide helps the clinician to determine the clinical features, severity, and etiology of chorea. In the first video (see Video 1), there is a discussion of the definition of chorea, its differential diagnosis, and underlying etiology. In the second video (see Video 2), the author demonstrates how to assess motor and nonmotor features of chorea in seven steps.
