太阳病发热，脉沉而细，名曰痉，为难治。痉脉按之紧如弦，直上下行。痉病发其汗已，其脉如蛇。
腹暴胀大者为欲解，脉如故，反伏弦者痉。（《金匮》）痉脉皆沉伏弦紧，但阳缓阴急，则久久拘挛，阴缓阳
急，则反张强直。二症各异，不可不别。（《三因》）

太阳病出现发热症状，若脉象沉而细，称为痉病，属于难治之证。痉病的脉象，按之感觉紧如弦状，上下直行。患痉病发汗后，其脉象变得像蛇行一样蜿蜒曲折。腹部突然胀大的是病情将要解除的表现；如果脉象依旧不变，反而出现伏弦的脉象，则是痉病。（出自《金匮要略》）痉病的脉象都是沉、伏、弦、紧，如果是阳缓阴急，就会长久地发生拘挛；如果是阴缓阳急，就会出现角弓反张、身体强直的症状。这两种病症表现不同，不可不加以辨别。（出自《三因极一病证方论》）

Taiyang disease (Disease of the Taiyang channel) presenting with fever, if the pulse is deep and fine, is termed Jing syndrome (Spasm), which is difficult to treat. The pulse of Jing syndrome feels tight like a string when pressed, running straight up and down. After inducing sweating in a patient with Jing syndrome, their pulse becomes winding like a snake. Sudden abdominal distension indicates that the condition is about to resolve; if the pulse remains unchanged but instead becomes hidden and wiry, it is Jing syndrome. (From *Jingui Yaolue*) The pulses of Jing syndrome are all deep, hidden, wiry, and tight. If Yang is relaxed and Yin is tense, chronic contracture occurs over time; if Yin is relaxed and Yang is tense, opisthotonos and rigidity occur. These two conditions differ in presentation and must be distinguished. (From *Sanyin Fang*)
