It contracts the muscles of the heart in order to enhance the rate of the heart.

Homan's Test is an
examination procedure of the ankle to test for dorsiflexion, which signals thromboembolism.
This is done by putting patient in supine position with leg straight, and then
raising the leg 10 degrees. The examiner will then dorsiflex the foot and
squeeze the calf. Pain in the calf upon flexion of the ankle with the leg
straight means a positive Homan's sign.
