Athletic Training Practice Exam

Question: 1 / 400

What does a positive Thompson's sign indicate?

Tight iliotibial band

Ruptured anterior tibialis tendon

Ruptured posterior tibialis tendon

Ruptured Achilles tendon

A positive Thompson's sign is a clinical test used to assess the integrity of the Achilles tendon. When the patient lies prone and the calf muscles are squeezed, the foot should plantarflex (point down) if the Achilles tendon is intact. A lack of movement in the foot during this squeezing indicates that the tendon may be ruptured. Therefore, a positive Thompson's sign specifically suggests a ruptured Achilles tendon, making this the correct answer.

The other conditions listed do not correlate with the purpose of the Thompson's test. A tight iliotibial band pertains to the lateral aspect of the knee and would not yield a positive response in a Thompson's test scenario. Similarly, issues related to the anterior or posterior tibialis tendons involve different motions and assessments, making them irrelevant when interpreting a positive Thompson's sign.
