What does the term 'athetotic' refer to in movement classification for CP?

The term 'athetotic' is specifically used to describe a type of movement characterized by slow, continuous writhing motions. This form of movement is often seen in individuals with athetoid cerebral palsy, which is a subtype of cerebral palsy that affects muscle tone and coordination. Athetosis can lead to involuntary movements that are not sudden or jerky, but rather fluid and can affect the hands, arms, legs, and even facial expressions.

Athetotic movements often result in difficulty maintaining a stable posture and can interfere with voluntary movements, as the continuous writhing can make it hard for individuals to perform tasks that require precision. Therefore, option C accurately reflects the nature of athetotic movements in the context of movement classification for cerebral palsy.
