Cryotherapy is the use of low temperatures in medical therapy. Cryotherapy is used to treat irritated tissue. "Cryotherapy" comes from the Greek cryo (κρυο) meaning cold, and therapy (θεραπεια) meaning cure. Cryotherapy has been used as early as the seventeenth century.
Cryotherapy's goal is to decrease cellular metabolism, increase cellular survival, decrease inflammation, decrease pain and spasm, and promote vasoconstriction. Cryotherapy is also known as ice pack therapy.
