Cryotherapy is the local or general use of low temperatures in medical therapy. Cryotherapy is used to treat a variety of benign and malignant tissue damage, medically called lesions. The term "cryotherapy" comes from the Greek ''cryo'' (κρύο) meaning ''cold'', and ''therapy'' (θεραπεία) meaning ''cure''. Cryotherapy has been used as early as the seventeenth century. Its goal is to decrease cell growth and reproduction (cellular metabolism), increase cellular survival, decrease inflammation, decrease pain and spasm, promote the constriction of blood vessels (vasoconstriction), and when using extreme temperatures, to destroy cells by crystallizing the cytosol, which is the liquid found inside cells, also known as intracellular fluid (ICF). The most prominent use of the term refers to the surgical treatment, specifically known as cryosurgery. Other therapies that use the term are whole-body cryotherapy〔 and ice pack therapy. == Hyperbaric gaseous cryotherapy == In 1993, Christian Cluzeau developed the hyperbaric gaseous cryotherapy also called NeuroCryoStimulation or NCS that can immediately relieve pain by acting on four physiological effects:〔Cluzeau, Christian and Mourot, Laurent (2010) ''La Cryotherapie Gazeuse Hyperbare Ou Neurocryostimulation''. Editions Universitaires Europeennes. ISBN 6131525455〕 # Painkiller # Vasomotor # Anti-inflammatory # Muscle relaxation This technique, practiced by some doctors, physiotherapists and veterinarians consists in applying for a short time on the skin up to the painful area, carbon dioxide at −78.3 °C (-109 °F) with a pressure of 50 bars and a frequency of 400 Hz. Sessions can be repeated at will. Unlike ice packs, the usage of carbon dioxide does not produce pain. Even if not as dangerous as liquid nitrogen used in cryosurgery, the low temperature could cause burns. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「cryotherapy」の詳細全文を読む スポンサード リンク
