“…Several authors (Medeiros, 2003;Poellnitz, 2018;Lima et al, 2013;Quarentei et al, 2008;Falcão & Guimarães, 2004;Joaquim et al, 2003;Toyoda & Akashi, 1993;Galheigo, 1988) debated about the terms occupation and activity and how they are used as synonyms, or they conceptualize or show other meanings, such as action, doing, praxis, among other terminological variations of the Brazilian occupational therapy. Silva (2013) and Salles & Matsukura (2016) point out that in the publications in this area, polysemy and plurality are evident in the construction of a field marked by diverse practices and knowledge. Benetton (2008) states that there is an indiscriminate use in the terms of activity, occupation, and occupational activity in Brazil, in which the "carelessness" in the adoption of the term occupation and its correlates make a conceptual confusion.…”
