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).
Rheumatic chorea is characterized by muscle weakness and the presence of chorea. The patients have the milkmaid grip sign, clumsy gait, and explosive bursts of dysarthric speech. Often, harlequin tongue, which pops in and out when the patient tries to hold it out, can be prominently demonstrated.
