What is chorea? Chorea refers to involuntary movements characterized by their random, brief, and non-rhythmic character. They are often described as seeming to âflowâ from one body part to another unpredictably, though they can also be confined to a single area of the body (such as the mouth area or hands).
Chorea is a major manifestation of acute RF and is the only evidence of RF in approximately 20% of cases. 1  In some outbreaks, chorea has been present in more than 30% of patients with acute RF. 2  The female-to-male ratio is approximately 2:1, and most patients present between 5-15 years of age.
