Relating to or affected by athetosis; showing characteristics of involuntary, writhing movements.
From 'athetosis' + the adjectival suffix '-ic.' This variant form is less common than 'athetotic' but appears in medical and scientific literature describing conditions involving athetotic movements.
Medical terminology has multiple valid forms—'athetosic' and 'athetotic' both work, but scientists seem to prefer 'athetotic' (sounds smoother), so 'athetosic' is the road less traveled!
