凡筋中于风热则弛纵，中于风冷则挛急。十二经之筋皆起于手足指，而络于身也。体虚
者，风冷之气中之，冷气停积，故结聚，谓之结筋也。
中恶者，是人精神衰弱，为鬼神之气卒中之也。夫人阴阳顺理，荣卫调平，神守则强，
邪不干正。若将摄失宜，精神衰弱，便中鬼毒之气。其状∶卒然心腹刺痛，闷乱欲死。
凡卒中恶，腹大而满者，诊其脉，紧大而浮者死，紧细而微者生。
又，中恶吐血数升，脉沉数细者死，浮焱如疾者生。
中恶者瘥后，余势停滞，发作则变成注。
中鬼邪之气，卒然心腹绞痛闷绝，此是客邪暴盛，阴阳为之难绝，上下不通，故气暴厥
绝如死；良久，其真气复，生也。而有乘年之衰，逢月之空，失时之和，谓之三虚；三虚而
腑脏衰弱，精神微羸，中之则真气竭绝，则死。其得瘥者，若余势停滞，发作则变成注。
尸厥者，阴气逆也。此由阳脉卒下坠，阴脉卒上升，阴阳离居，荣卫不通，真气厥乱，
客邪乘之，其状如死，犹微有息而不恒，脉尚动而形无知也。听其耳内，循循有如啸之声，
而股间暖是也。耳内虽无啸声，而脉动者，故当以尸厥治之。
诊其寸口脉，沉大而滑，沉即为实，滑即为气，实气相搏，身温而汗，此为入腑，虽卒
厥不知人，气复则自愈也。若唇正青，身冷，此为入脏，亦卒厥不知人，即死。候其左手关
上脉，阴阳俱虚者，足厥阴、足少阳俱虚也，病苦恍惚，尸厥不知人，妄有所见。
凡是筋脉受到风热邪气侵袭，就会松弛纵缓；受到风冷邪气侵袭，就会拘挛紧急。十二经之筋都起始于手足的指端，并联络全身。身体虚弱的人，风冷之气侵入体内，冷气停滞积聚，从而形成结聚，这被称为“结筋”。
所谓“中恶”，是指人的精神衰弱，被鬼神之类的气突然袭击所致。人如果阴阳顺理，营卫调和平衡，神志守持则身体强健，邪气不能侵犯正气。如果调养失当，精神衰弱，就会遭受鬼毒之气的侵袭。其症状表现为：突然心腹刺痛，烦闷混乱，痛苦欲死。凡是突发中恶，腹部胀大且满实的，诊察其脉搏，若脉象紧大而浮的预后不良（主死），若脉象紧细而微弱的则有生机（主生）。
另外，中恶导致吐血数升的，若脉象沉、数、细的预后不良（主死），若脉象浮浅且快速有力的则有生机（主生）。
中恶病痊愈后，若余留的病势停滞不去，再次发作时就会转变为“注病”（一种具有传染性或迁延难愈的疾病）。
遭受鬼邪之气侵袭，突然发生心腹绞痛、昏厥窒息，这是因为客邪暴盛，导致阴阳之气难以接续，上下不通，所以气机突然厥逆闭塞，状如死亡；经过较长时间，真气恢复，就能存活。但是，如果遇到年运衰退（岁气不及）、月亮亏空之时（月廓空）、以及四时气候失调的情况，这就称为“三虚”；在三虚的情况下，脏腑功能衰弱，精神轻微亏损，此时再受邪气侵袭，就会导致真气竭绝，从而死亡。那些能够痊愈的人，如果余留的病势停滞不去，再次发作时也会转变为注病。
尸厥证，是由于阴气上逆所致。这是由于阳脉突然下陷，阴脉突然上升，导致阴阳分离，营卫之气不通，真气厥乱，客邪乘虚而入。其症状表现如同死亡，但仍有微弱的呼吸且不规律，脉搏尚且跳动而形体无知觉。在耳内倾听，能听到类似呼啸的声音，且大腿内侧温暖，这就是尸厥的表现。即使耳内没有呼啸声，只要脉搏跳动，就应当按尸厥来治疗。
诊察寸口脉，若脉象沉大而滑，沉代表实邪，滑代表气滞，实邪与气滞相互搏结，身体温热且有汗出，这是病邪入腑，虽然突然厥逆不知人事，但气机恢复后就能自愈。如果嘴唇正青色，身体冰冷，这是病邪入脏，同样是突然厥逆不知人事，但会立即死亡。诊察左手关部脉，若阴阳两虚，说明足厥阴肝经和足少阳胆经都虚弱，病人苦于神志恍惚，出现尸厥不知人事，甚至产生幻觉妄见。
Whenever sinews are invaded by wind-heat pathogenic factors, they become flaccid and lax; when invaded by wind-cold pathogenic factors, they become spasmodic and tight. The sinews of the twelve meridians all originate from the fingers and toes of the hands and feet, and network throughout the body. In individuals with a weak constitution, wind-cold qi invades the interior, where cold qi stagnates and accumulates, forming knots, which is termed "Jiejin" (Sinew Knots).
The condition known as "Zhong'e" (Sudden Attack by Evil) occurs when a person's spirit is depleted and suddenly assaulted by the qi of ghosts or evil spirits. When a person's yin and yang are in harmony, and Ying (Nutritive) and Wei (Defensive) qi are balanced, the spirit remains steadfast, making the body strong so that pathogenic factors cannot invade the healthy qi. However, if proper care is neglected and the spirit becomes depleted, one may be struck by the toxic qi of ghosts. The manifestations include sudden stabbing pain in the heart and abdomen, severe distress, confusion, and a sensation of impending death. In cases of sudden Zhong'e with abdominal distension and fullness, if the pulse is tight, large, and floating, it indicates a fatal prognosis; if the pulse is tight, fine, and faint, it indicates survival.
Furthermore, in Zhong'e accompanied by hematemesis of several sheng, if the pulse is deep, rapid, and fine, it indicates a fatal prognosis; if the pulse is superficial, blazing, and rapid, it indicates survival. After recovering from Zhong'e, if residual pathogenic factors remain stagnant, subsequent attacks may transform into "Zhu" (Peripatetic Disease/Contagious Disease).
When attacked by the qi of ghostly pathogens, sudden severe cramping pain in the heart and abdomen with syncope and suffocation occurs. This is due to the violent excess of exogenous pathogens, causing difficulty in the connection of yin and yang, obstruction of upper and lower communication, leading to sudden rebellion and closure of qi, resembling death; after a long period, if true qi recovers, life is preserved. However, if one encounters the decline of the annual climate (Year of Decline), the emptiness of the lunar phase (Moon Emptiness), and disharmony of seasonal conditions, this is called "Sanxu" (Three Deficiencies). Under these three deficiencies, with weakened zang-fu organs and slightly emaciated spirit, invasion by pathogens leads to exhaustion of true qi and death. Those who recover, if residual pathogenic factors remain stagnant, may also transform into Zhu upon recurrence.
Shijue (Corpse-like Syncope) is caused by the rebellion of yin qi. It arises because yang meridians suddenly sink downward while yin meridians suddenly rise upward, causing separation of yin and yang, obstruction of Ying and Wei qi, disorder of true qi, and invasion by exogenous pathogens. The condition resembles death, yet there is still faint, irregular respiration, and although the pulse beats, the body is insensible. Listening near the ear reveals a whistling sound, and warmth in the groin area characterizes Shijue. Even without the whistling sound, if the pulse beats, it should be treated as Shijue.
Palpating the Cun Kou (Radial Pulse), if the pulse is deep, large, and slippery: deep indicates excess, slippery indicates qi stagnation; the struggle between excess and qi stagnation results in a warm body with sweating. This indicates the pathogen has entered the Fu organs; although sudden syncope with loss of consciousness occurs, self-recovery follows upon restoration of qi. If the lips are cyanotic and the body is cold, this indicates the pathogen has entered the Zang organs; similarly involving sudden syncope and loss of consciousness, but resulting in immediate death. Palpating the Guan position on the left hand: if both yin and yang pulses are deficient, it indicates deficiency of the Foot Jueyin Liver Meridian and Foot Shaoyang Gallbladder Meridian. The patient suffers from mental confusion, Shijue with loss of consciousness, and visual hallucinations.
