Rehabilitation treatment taxonomy: establishing common ground.

This article introduces the Archives supplement presenting a conceptual framework for the creation of a rehabilitation treatment taxonomy (RTT). It describes the key theoretical and empirical articles and their role, and the commentaries that were solicited. More importantly, based on feedback received to date, it sketches what the RTT is proposed to address, and what it explicitly excludes; therefore, the readers will have appropriate expectations and criteria for what is offered.
