Athetoid

A type of involuntary movement characterised by slow, continuous, writhing motions, particularly affecting the hands, fingers, and face. Athetoid movements are commonly associated with athetoid cerebral palsy, a subtype of cerebral palsy that results from damage to the basal ganglia. People with athetoid movements may have significant difficulty with precise motor tasks such as typing, using a mouse, or activating small targets on screen. Assistive technology accommodations include larger target sizes, key guards, reduced sensitivity settings, and alternative input devices.
