Foot pumps are simple exercises for early leg rehabilitation where the foot is 'pumped' up and down to improve the blood flow of the limb and prevent stasis of the blood that may cause thrombosis.

foot pumps

 

Forcibly rocking the foot from the ankle activates the muscle pump in the calf.

venous pump of the calf

Because of the valves in the veins, as the calf muscles contract and compress the vein the blood can only move in one direction - back to the heart.

 

 

The muscle pump in the calf

The veins of the lower limbs rely on a series of valves to help move the blood back to the heart. As the calf muscles contract, the blood - unable to go back down because of the valves - moves up back to the heart. This keeps the circulation going, and helps to prevent blood clots in the calf (deep vein thrombosis).

Why is it important to prevent deep vein thrombosis?

Deep vein thrombosis can be a killer if the peripheral blood clot breaks off and shoots up the blood vessels into the heart and lungs. Patients having knee surgery who are deemed at high risk will likely be given medication for a few days to try and prevent clots forming.

    "....active ankle movement can produce higher [maximum venous capacity] and [maximum venous outflow] and faster blood velocity, possibly through the activation of the [calf muscle pump], and it promotes venous return and vein circulation....[and] is effective in preventing the formation of lower-extremity [deep vein thrombosis] after orthopedic surgery, accelerating postoperative recovery and improving patient satisfaction. "
