thompson test

Thompson's test: tests whether the Achille's tendon is intact. If the Achilles' tendon is intact, when the calf muscle is squeezed, the foot will plantar-flex. If the Achilles' tendon is ruptured, the foot will NOT plantar-flexed as the calf muscle is squeezed.


Why it works? The soleus & gastrocnemius make up the calf muscles. Both of these 2 muscles attach to the Achilles' tendon. Therefore, when the you squeeze the calf muscles, you are trying to lift these 2 muscles up contracting the muscles leading to the plantar-flexion of the foot.
