Apprehension Test
A clinical examination technique that reproduces the position of potential joint dislocation to assess instability, most commonly used for shoulder and patella evaluation.
Full Definition
The apprehension test is a clinical examination maneuver designed to assess joint instability by placing the joint in a position that would predispose it to dislocation or subluxation. The test is positive when the patient experiences anxiety, apprehension, or protective muscle guarding as the examiner moves the joint toward the unstable position. Most commonly performed for anterior shoulder instability (with the arm in abduction and external rotation) and patellar instability (with lateral pressure on the patella), this test helps identify patients with recurrent instability patterns. In orthopedic rehabilitation, the apprehension test serves both diagnostic and therapeutic monitoring purposes, helping clinicians assess progress in stability training and determine readiness for return to activities that might provoke instability episodes.
Usage
Usage note: Specify anatomical location (shoulder, patella, etc.) and direction of instability being tested.
