Before choosing a uniform name for the PMR specialty, we must define the specialty.

In this letter, I develop the recent proposal to choose a uniform name globally for our specialty ("A call for a single international name for the specialty"), suggesting it is premature and we must first agree on the core, central features characterizing a specialist. The question is, what is our specialty? The scope and content vary significantly between and within countries. If we can agree on the nature and scope of the specialty, a one-word name may arise that people and countries could choose to use.
