'adiadochokinesis' originates from Greek, specifically the word 'adiadochos,' where 'a-' meant 'not,' 'diadochos' meant 'succeeding,' and 'kinesis' meant 'movement.'

'adiadochos' transformed into the modern English word 'adiadochokinesis' through medical terminology.

Initially, it meant 'not succeeding in movement,' and this meaning has largely remained the same in modern medical usage.
