CATs Critically Appraised Topics
for Orthotics and Prosthetics



The ultimate objective of Critically Appraised Topics (CATs) is to facilitate the transfer of knowledge derived from published evidence into clinical practice.

Critically appraised topics (CATs)

A critically appraised topic (CAT) is a standardized, brief summary of research evidence organized around a clinical question. CATs are intended to provide both a critical summary of primary knowledge sources (e.g., journal articles) as well as statements regarding the clinical relevance of the results. As such, they represent a translation of primary knowledge sources into more accessible secondary knowledge sources, with the ultimate objective of facilitating the transfer of knowledge derived from published evidence into clinical practice.

The Academy Secondary Knowledge Committee is focused on aiding Academy members' consumption of academic research in terms of access, quantity, and clinical implementation. One of the committee's goals is to develop this library of CATs. CATs are reviewed by the committee and, when appropriate, by a person with advanced knowledge of the particular topic.
