In a patient with a ruptured Achilles tendon, the foot will not move. That is called a positive Thompson test. The Thompson test is important because some people who tear their Achilles are still able to point their toes downwards, although the Thompson test would still be positive.
An achilles reflex test determines if the sciatic nerve is functioning properly. Physical therapy can help relieve pressure on the sciatic nerve. The sciatic nerve passes through from the back down to the leg. Type 1 diabetes can cause the Achilles reflex response to become latent or absent.Abnormal reflexes may be caused by chronic alcoholism.ircumstances under which the Achilles reflex may be examined include tests of sciatic nerve function. If the roots of S1 and S2 are damaged in any way, such as by pinching where they exit the spine or by disk herniation, the reaction may be delayed or diminished.
