Etymology
Etymology Information

'athetosis' originates from Greek, specifically the word 'ἀθετωσις' (transliterated 'athetōsis'), where the prefix 'a-' meant 'not' and the root related to 'thetos' meant 'placed' or 'fixed'.

Historical Evolution

'athetosis' entered medical English from New Latin/Greek usage in the late 19th century as a technical term describing 'unfixed' or 'not-positioned' movements and became established in neurology to denote writhing involuntary movements.

Meaning Changes

Initially, it meant 'a state of not being fixed or placed,' but over time it evolved into its current medical meaning of 'involuntary writhing movements.'
