The use and misuse of performance testing.

Abstract

It is important to consider what performance testing can tell us and what it cannot. A performance test is a "snapshot" which says something about the ability of a patient to execute a specific task. This snapshot is reflective of only that moment in time. If there are no other available tests or there are no normative data from which to formulate a sound clinical plan, the test is at best misleading and at worst completely useless. The drive to utilize performance testing has resulted from an increased demand for accountability and objectivity. It is valuable to keep in mind, however, that if the correct questions are asked and the appropriate equipment and staff are available, performance testing can have an important place in rehabilitation of the spine.
