Thompson Test

The Thompson Test (pronounced: Tom-son Test), also known as the Thompson's squeeze test or the Simmonds-Thompson test, is a physical examination procedure used to diagnose a rupture of the Achilles tendon. The test is named after the British orthopedic surgeon, Dr. Frank N. Thompson, who first described it in 1962.

Etymology

The term "Thompson Test" is derived from the name of its originator, Dr. Frank N. Thompson. The term "Simmonds-Thompson test" is sometimes used to acknowledge the contribution of Dr. Percival Pott Simmonds, who independently described a similar test.

Procedure

The Thompson Test is performed with the patient lying prone (face down) on an examination table. The examiner squeezes the calf muscle, and if the Achilles tendon is intact, this action will cause the foot to plantar flex (point downwards). If the Achilles tendon is ruptured, the foot will not move, indicating a positive Thompson Test.

Related Terms

  • Achilles tendon: A tough band of fibrous tissue that connects the calf muscles to the heel bone.
  • Prone position: A body position in which one lies flat with the chest down and the back up.
  • Plantar flexion: The movement of the foot that flexes the foot or toes downward toward the sole.
