Simmonds' test

Simmonds' test (also called the Thompson test or Simmonds-Thompson test) is used in lower limb examination to test for the rupture of the achilles tendon. The patient lies face down with feet hanging off the edge of the bed. If the test is positive, there is no movement of the foot (normally plantarflexion) on squeezing the corresponding calf, signifying likely rupture of the achilles tendon.

Etymology
It is named after Franklin Adin Simmonds (1911-1983), an English orthopaedic surgeon at the Rowley Bristow Hospital, Surrey.
