What feature distinguishes chorea from tremors and tics?

Explanation:
Chorea is defined by irregular, quick, non-rhythmic movements that flow unpredictably from one part of the body to another. This randomness is what sets it apart. Tremors, in contrast, are rhythmic and oscillatory, with a regular pattern or frequency. Tics are sudden, brief, repetitive, and often somewhat stereotyped movements that people can sometimes suppress for short periods. So the defining feature distinguishing chorea from tremors and tics is the randomness and lack of a fixed rhythm in choreic movements.
