[Beginning of the institutionalization of physical therapy in a Swiss canton: 1928-1945]

The institutionalization of physical therapy in Switzerland took place in the inter-war period. This article aims to relate the initiation of this process in the Canton of Vaud, as a specific example that will nevertheless be compared with the Swiss and international contexts. This story occurs around three major events between 1928 and 1945: the massage becomes a regulated profession, followed by the emergence of a professional association and a specialized school. The intention is first to identify the social actors, then the interests, issues, and interactions that have contributed to model the modern physical therapy. Finally, the techniques used by the masseurs--the first professional physical therapists--and their working environment are evoked.
