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.
The Thompson test is performed when making the diagnosis of a torn Achilles tendon. This should not be confused with the Thomas test, used to asses for hip joint problems. An Achilles tendon tear occurs with the tendon that connects the calf muscle to the heel bone is severed. This injury often occurs during sports activities such as basketball or tennis, and is felt by the athlete as a sudden sharp pain directly behind the ankle.
