Heat therapy - Onnetsuryoho

Japanese: 温熱療法 - おんねつりょうほう
Heat therapy - Onnetsuryoho
A physical therapy that uses heat. Examples include conductive heat-based hot compresses (a treatment in which a part of the body is covered with a cloth or other material to apply heat stimulation), paraffin baths (a treatment in which the affected part is placed in and out of a bath of melted paraffin for a few seconds to treat rheumatoid arthritis, hip joint contracture, and to relieve pain), infrared radiation and hot air baths (hot air therapy) that use radiant heat, electric therapies such as ultrashort waves that use high frequencies, and hot baths as hydrotherapy. The effects of heat include improving peripheral circulation, increasing blood flow due to heartbeat, promoting sweating and metabolism, relieving muscle tension, and having an analgesic effect. It is widely used in a variety of applications, from rehabilitation for sprains and joint pain to cancer treatment. Focusing on the fact that cancer is sensitive to heat above 42.5°C, hyperthermia therapy, which heats cancer tissue with microwaves that produce heat of 43°C, is used mainly for skin cancer, and can be expected to be more effective when used in combination with radiation therapy or anticancer drugs. However, there is no established method for applying heat only to cancer cells deep inside the body, and there is a serious problem that normal tissues can also be affected. In September 1996, a research group from the Nagoya University School of Engineering announced a new type of hyperthermia therapy that can kill only cancer cells by placing tiny magnets inside the cells and irradiating them with relatively low-frequency electromagnetic waves, which caused a stir. However, the reality is that hyperthermia is still not an established treatment method. →High-frequency therapy→Related topic: Physical therapy

Japanese:
温熱を利用した物理療法のこと。伝導熱を利用した温罨(あん)法(身体の一部を布などで被って温熱刺激を与える治療法)やパラフィン浴(関節リウマチや股関節の拘縮,および疼痛の軽減を目的として,溶解させたパラフィンの浴槽中に患部を数秒間出し入れする治療法),輻(ふく)射(放射)熱を利用した赤外線照射や熱気浴(熱気療法),高周波を利用した超短波などの電気療法,水治療としての温浴などがある。 温熱効果としては,末梢循環の改善,心拍による血液の出量の増大,発汗や新陳代謝の促進,筋緊張の緩和,鎮痛作用など。捻挫(ねんざ)や関節痛のリハビリテーションから癌(がん)治療まで,幅広く適用されている。 癌が42.5℃以上の熱に弱いことに着目し,43℃の熱の出るマイクロ波で癌組織を加温する温熱療法は,特に皮膚癌を中心に行われており,放射線治療や制癌薬(抗癌剤)と併用することによって,より高い効果が期待できる。しかし,身体の深部にある癌細胞だけに加温する方法が確立されておらず,正常な組織にまで影響を与えてしまうという重大な問題がある。 1996年9月,名古屋大学工学部の研究グループによって,微小な磁石を癌細胞の中に入れ,比較的低い周波数の電磁波を照射して,癌細胞だけを死滅させることができる新しい温熱療法が発表され,話題となった。しかし,温熱療法はまだまだ確立された治療法とはいえないのが現実である。→高周波療法
