The Thompson test examines the integrity of the Achilles tendon by squeezing the calf. It is performed as a clinical test to identify the presence of a complete Achilles rupture.
Purpose
The goal of this test is to find out if there is a complete tear present in the Achilles tendon.
Technique
The patient lies prone with his foot over the end of the table. Alternatively, the patient could lie prone with his knee flexed to 90°. The examiner squeezes the calf muscles, specifically the gastrocnemius - soleus complex, with his hand. Squeezing the calf should cause contraction of the Achilles tendon, resulting in plantar flexion. If the Achilles tendon is completely ruptured, there will not be any apparent plantar flexion.
