The research object of the present paper is the language of physiotherapy, analyzed on the basis of records of an oral communication between specialists in movement rehabilitation and patients, and the corpus of articles of informative character, yet not on specialist but on popular science level, written by trained physiotherapists and addressed to non-expert readers seeking advice on the treatment of diseases and dysfunctions of the spinal column. The language of physiotherapists, who are officially representatives of the health system, relies heavily on the language of medicine, but its specificity is also due to its strong links with sport, biomechanics, healthcare, fitness industry, and social psychology, as well as to the character of the interaction between physiotherapists and patients. The conducted analysis enabled to identify typical lexical and morphosyntactic features of the language of physiotherapy. The discussed subject is in line with the research on effective communication between the patient and health providers which is essential for the delivery of high-quality medical care.
