Resembling or having the characteristics of chorea, which is a movement disorder that causes involuntary, erratic movements.
The patient's movements were described as choreiform, making it difficult for him to sit still.
Choreiform → It is formed from "choreia" (from Greek, meaning dance) and "-form" (meaning shape or form). The word describes a shape or movement resembling a dance, often used in a medical context to refer to involuntary movements that appear dance-like.
Imagine movements that look like a 'dance' ('choreia') — that's why 'choreiform' describes those dance-like motions.
