Physical Assessment (PA) Lower Extremity (LE) Practice Test

The patellar apprehension test is specifically designed to evaluate the stability of the patella and assess the risk of patellar dislocation. During the test, the clinician applies lateral pressure to the patella while observing the patient’s response. If the patient shows signs of apprehension or flinches, it suggests that there is a potential instability of the patella, indicating a higher risk for dislocations. This test is particularly significant in individuals who have experienced previous patellar injuries or who report a sensation of the knee giving way during activities.

The other options do not align with the primary purpose of the patellar apprehension test. Measuring overall leg strength involves different assessments focused on muscular endurance and power rather than joint stability. Identifying ankle ligament tears requires different examinations, such as the anterior drawer test or talar tilt test, that specifically assess the integrity of the ankle ligaments. Testing for quadriceps muscle activation typically involves functional movement assessments and electromyography, rather than focusing on patellar stability.
