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

The Thompson test is specifically designed to assess the integrity of the Achilles tendon. During this test, the patient is positioned prone with their feet hanging off the edge of the examination table. When the examiner squeezes the calf muscles, a normal response is observed if the Achilles tendon is intact, which results in plantarflexion of the foot. Conversely, if there is a rupture of the Achilles tendon, there will be no movement of the foot upon squeezing the calf.

This test is considered reliable and effective for identifying an Achilles tendon rupture, making it the appropriate choice for confirming a suspected injury in that area. It is important to note that the other tests mentioned are focused on different joints and ligaments; for example, the Apley test is used for meniscal injury in the knee, the McMurray test also assesses for meniscal tears, and the Anterior drawer test evaluates instability of the ankle by assessing the integrity of the anterior talofibular ligament. Therefore, these options do not pertain to the examination of the Achilles tendon.
