[Excerpt] We appreciate the interest that Mr Inverso expressed in our work, and we are pleased that it stimulated discussion about the roles of physical therapist assistant (PTA). Mr Inverso noted that he had "significant concerns" about the design of the research. We would contend, however, that his primary concern is not relevant to design, but instead flows from a linguistic interpretation of the phrase "support personnel." Although this concern is valid and important to discuss, it does not pertain to the methodological rigor of the research.
