The article is devoted to a review of the 3rd international online school on the physiology of expressive movement “Rehabilitation. Art. Pedagogy”, which took place on November 16th, 2022. The main topic of the scientific discussion was the phenomenon of expressive movement as a manifestation of the creative and motor abilities of a person, as well as it being one of the possible markers of his inner, spiritual world. Two previous online schools have shown that this topic seems to be very interesting to a wide range of scientific community, which includes representatives of the medical rehabilitation sphere, the performing arts, dance history researchers, physiologists and body-oriented therapists. However, this time the concept of the school was aimed at finding points of contact between the direct experience of theatre pedagogy and practicing psychologists and physiologists. This concept has become not only a characteristic feature of the 3rd online school, but also revealed a special scientific approach, which is the interdisciplinary nature of the discussion. The event was organized by the Russian Medical Academy of Continuing Professional Education of the Ministry of Health of the Russian Federation together with the Russian Institute of Theatre Arts (GITIS) (as a part of the “Priority-2030” Strategic Academic Leadership Program) under the support of the National Association of Physiotherapy and Balneology. Such a scientific union is significant for further research. Since the school is an interdisciplinary one, which makes it unique, the article presents brief summaries of the reports that present a wide range of scientific and practical issues of physiotherapy, rehabilitation, theatre pedagogy, and the history of plastic expressiveness.
