physiotherapy

Etymology

It is formed from English physio- + therapy,^{[2][3][4][5][6]} modelled on French physiothérapie, recorded in 1903.^[2] Merriam-Webster takes it from New Latin physiotherapia.^[7] The first element goes back to Ancient Greek φύσις (phúsis, “nature”),^[2][3] and therapy to therapia, from Ancient Greek θεραπεία (therapeía, “healing”).^[2][3] The OED compares the earlier physiatrics and the slightly later physicotherapy.^[2]

Earliest recorded meaning

The treatment of injury, disease or pain by physical methods rather than drugs: 1900, in W. A. N. Dorland's American Illustrated Medical Dictionary.^[2] Barnhart and Etymonline give 1905,^[4][3] Merriam-Webster about 1900.^[7]

Semantic evolution

The word has kept its first meaning, treatment by manipulation, massage, exercise, heat, light and the like.^[2][5] A practitioner has been a physiotherapist since 1922, and the American physical therapy is recorded from 1919.^[2] In British use both were shortened to physio, the therapist from 1962 and the therapy from 1967.^[2][8]
