Data were submitted to prototypical analysis, using two analysis techniques of centrality, similarity and double negation. Results: The evocations “care” and “decubitus” made up the central core of the representation, which was structured based on the imagery dimension of changing position, from which a hierarchy of preventive measures occurs.
