此由体虚腠理开，风邪在于筋故也。春遇痹，为筋痹，则筋屈，邪客关机，则使筋挛。
邪客于足太阳之络，令人肩背拘急也。足厥阴，肝之经也。肝通主诸筋，王在春。其经络虚
，遇风邪则伤于筋，使四肢拘挛，不得屈伸。
诊其脉，急细如弦者，筋急足挛也。若筋屈不已，又遇于邪，则移变入肝。其病状，夜
卧则惊，小便数。其汤熨针石，别有正方，补养宣导，今附于后。
《养生方·导引法》云∶手前后递互拓，极势三七，手掌向下，头低面心，气向下至涌
泉、仓门，却努一时取势，散气，放纵。身气平，头动，膊前后欹侧，柔膊二七。
去膊井冷血。筋急，渐渐如消。
又云∶两手抱左膝，伸腰，鼻纳气七息，展右足，除难屈伸拜起，胫中痛萎。
又云∶两手抱右膝着膺，除下重难屈伸。
又云∶踞坐，伸右脚，两手抱左膝头，伸腰，以鼻纳气，自极七息，展右足着外。除难
屈伸拜起，胫中疼痹。
又云∶立身，上下正直，一手上拓，仰手如似推物势，一手向下如捺物，极势，上下来
去，换易四七。去膊内风，两膊井内冷血，两掖筋脉挛急。
又云∶踞坐，伸左脚，两手抱右膝，伸腰，以鼻纳气，自极七息，展左足着外。除难屈
伸拜起，胫中疼痹。
风身体手足不随者，由体虚腠理开，风气伤于脾胃之经络也。足太阴为脾之经，脾与胃
合。足阳明为胃之经，胃为水谷之海也。脾候身之肌肉，主为胃消行水谷之气，以养身体四
肢。脾气弱，即肌肉虚，受风邪所侵，故不能为胃通行水谷之气，致四肢肌肉无所禀受；而
风邪在经络，搏于阳经，气行则迟，机关缓纵，故令身体手足不随也。
诊脾脉缓者，为风痿，四肢不用。又心脉、肾脉俱至，则难以言，九窍不通，四肢不举
。肾脉来多，即死也。其汤熨针石，别有正方，补养宣导，今附于后。
《养生方·导引法》云∶极力左右振两臀，不息九通，愈臀痛劳倦，风气不随。振两臀
者，更互 ，犹言厥，九通中间，偃伏皆为之，名虾蟆行气，久行不已，愈臀痛
劳倦，风气不随，不觉痛痒，作种种形状。
又云∶偃卧，合两膝，布两足，伸腰，口纳气，振腹自极七息。除壮热疼痛，两胫不随
又云∶治四肢疼闷及不随，腹内积气，床席必须平稳，正身仰卧，缓解衣带，枕高三寸

之，为一息；一息数至十息，渐渐增益，得至百息、二百息，病即除愈。不用食生菜及鱼肥
肉。大饱食后，喜怒忧恚，悉不得辄行气。惟须向晓清静时行气，大佳，能愈万病。
这是因为人体正气虚弱，腠理（皮肤纹理及汗孔）疏松敞开，风邪侵入筋脉所致。春季遇到痹证，称为筋痹，会导致筋脉收缩；邪气客居关节，就会使筋脉拘挛。
邪气侵犯足太阳膀胱经的络脉，使人肩背部拘急僵硬。足厥阴肝经是肝脏的经脉。肝主管全身的筋脉，在春季当令。如果其经络气血虚弱，遇到风邪就会损伤筋脉，导致四肢拘挛，无法屈伸。
诊察患者的脉象，如果脉象紧急、细弱且如琴弦般紧绷，这是筋脉拘急、足部挛缩的表现。如果筋脉收缩不止，又再次遭受邪气侵袭，病邪就会传入肝脏。此时的病症表现为夜间睡眠时易受惊吓，小便频数。关于汤药外敷、熨烫、针刺和砭石治疗，另有专门的方剂，补益调养和导引宣通的方法，现在附在后面。
《养生方·导引法》说：双手前后交替用力推拓，达到极限共二十一次（三七二十一），手掌向下，头部低垂面向心窝，气息下沉至涌泉穴、仓门穴，然后暂时憋气努劲片刻以调整姿势，随后散气放松，舒展身体。待身体气息平稳，头部转动，双肩前后倾斜侧动，柔缓地做十四次（二七十四）。这样可以去除肩部井穴处的冷血。筋脉拘急的症状会逐渐消除。
又说：双手抱住左膝，伸直腰背，用鼻子吸气七次呼吸（七息），伸展右腿。这可以治疗难以屈伸、拜起困难以及小腿疼痛萎软的症状。
又说：双手抱住右膝贴近胸膺，可以治疗下肢沉重、难以屈伸的症状。
又说：蹲坐，伸出右脚，双手抱住左膝盖，伸直腰背，用鼻子吸气，尽力做到七次呼吸，将右腿向外伸展。这可以治疗难以屈伸、拜起困难以及小腿疼痛麻木的症状。
又说：站立，身体上下正直，一只手向上推拓，手掌仰起如同推物的姿势，另一只手向下按压如同捺物，达到极限，上下往复运动，更换动作共三十二次（四七三十二）。这可以去除肩部内的风邪和两肩井穴内的冷血，缓解两腋下筋脉的拘挛急迫。
又说：蹲坐，伸出左脚，双手抱住右膝，伸直腰背，用鼻子吸气，尽力做到七次呼吸，将左腿向外伸展。这可以治疗难以屈伸、拜起困难以及小腿疼痛麻木的症状。
风邪导致身体手足不能随意运动（不随），是因为人体正气虚弱，腠理疏松，风气伤害了脾胃的经络。足太阴脾经是脾脏的经脉，脾与胃相表里。足阳明胃经是胃的经脉，胃被称为水谷之海。脾对应身体的肌肉，主要协助胃消化运输水谷的精微之气，以滋养身体四肢。脾气虚弱，肌肉就会空虚，受到风邪侵袭，因此不能帮助胃通行水谷的精微之气，导致四肢肌肉得不到滋养；而风邪停留在经络中，搏结于阳经，气机运行迟缓，关节松弛放纵，所以导致身体和手足不能随意运动。
诊察脾脉，如果脉象缓弱，这是风痿症，表现为四肢不能使用。如果心脉和肾脉同时出现异常，则说话困难，九窍不通，四肢无法抬起。如果肾脉来势过盛，则预后不良，可能导致死亡。关于汤药外敷、熨烫、针刺和砭石治疗，另有专门的方剂，补益调养和导引宣通的方法，现在附在后面。
《养生方·导引法》说：极力左右振动两臀部，憋气九次（九通），可以治愈臀部疼痛和劳倦，以及风气导致的手足不遂。所谓振动两臀部，是交替震动，就像“厥”的意思一样，在九次憋气的过程中，俯卧伏地都要这样做，名叫“虾蟆行气”，长期练习不止，可以治愈臀部疼痛和劳倦，以及风气导致的手足不遂、感觉不到痛痒，并做出各种形状的动作。
又说：仰卧，双膝并拢，双脚分开，伸直腰背，用口吸气，振动腹部直到极限，进行七次呼吸。这可以治疗高热疼痛和小腿不能随意运动的症状。
又说：治疗四肢疼痛烦闷及不能随意运动，腹内积气，床席必须平稳，身体正仰卧，解开衣带，枕头高三寸，手握固（握固是一种手势，即拇指被其余四指握住）。所谓握固，是用两手各自将四指包裹住拇指，舒展手臂，使手臂离开身体各五寸，两脚竖起脚趾，两脚相距五寸，安心定意，调和气息，不要思考其他事情，专心意念引导气息，慢慢地漱口生津（漱醴泉）。所谓漱醴泉，是用舌头舔舐嘴唇、口腔和牙齿，然后吞咽唾液，慢慢地用口呼气，用鼻吸气进入喉咙。需要微微缓慢地进行，不可突然急促强行操作，等待气息完全调和。引导气息和呼出气息，不要让自己听到进出气的声音。每次引导气息时，心中意念随之送气，从脚趾头让气排出。引导气息五次或六次后，呼出一口气，算作一次呼吸；一次呼吸的次数增加到十次，逐渐增加，直到达到一百次、二百次，疾病即可消除痊愈。期间不吃生菜以及鱼和肥腻的肉。在大饱食之后，以及处于喜怒忧恚等情绪波动中，都不得立即进行行气练习。只须在清晨清静之时进行行气练习，非常好，能够治愈万病。
This condition arises because the body's healthy qi is deficient, causing the cou li (the texture of the skin and interstices, including sweat pores) to open, allowing wind pathogenic factors to invade the sinews. In spring, encountering bi syndrome results in sinew-bi, leading to sinew contraction; when pathogens lodge in the joints, they cause sinew spasm.
When pathogens invade the collaterals of the Foot-Taiyang Bladder Meridian, it causes stiffness and tightness in the shoulder and back. The Foot-Jueyin Liver Meridian is the meridian of the Liver. The Liver governs all sinews and is predominant in Spring. If its meridians are deficient and wind pathogens are encountered, the sinews are damaged, resulting in spasms and contractures of the four limbs, preventing flexion and extension.
Upon pulse diagnosis, if the pulse is rapid, thin, and taut like a string, it indicates sinew tension and foot contracture. If the sinew contraction persists and is further exposed to pathogens, the disease may transmit into the Liver. The symptoms include being startled during sleep at night and frequent urination. Treatments involving decoctions, hot compresses, acupuncture, and stone therapy have separate specific formulas. Methods for tonification, nourishment, and guiding/dispersing qi are attached below.
The "Health Preservation Formulas · Daoyin Methods" states: Push and pull alternately with both hands forward and backward to the utmost extent, repeating this twenty-one times (3 x 7). Palms face downward, head lowered facing the heart, directing qi down to Yongquan (KI1) and Cangmen (ST10) acupoints. Then, hold breath and exert force briefly to adjust posture, then release the qi and relax. When body qi is calm, move the head, tilting shoulders forward and backward obliquely, performing fourteen gentle repetitions (2 x 7). This removes cold blood from the Jing (Well) points of the shoulders. Sinew tension will gradually dissipate.
It also states: Embrace the left knee with both hands, extend the waist, inhale through the nose for seven breaths, and extend the right leg. This treats difficulty in flexion and extension, difficulty in bowing and rising, and pain or atrophy in the shins.
It also states: Embrace the right knee against the chest/epigastrium. This treats heaviness in the lower body and difficulty in flexion and extension.
It also states: Sit in a squatting position, extend the right foot, embrace the left knee with both hands, extend the waist, inhale through the nose, and strive for seven breaths. Extend the right foot outward. This treats difficulty in flexion and extension, difficulty in bowing and rising, and pain or numbness in the shins.
It also states: Stand upright, straightening the body from top to bottom. One hand pushes upward, palm up as if pushing an object; the other hand presses downward as if pressing on something. Perform this to the utmost extent, moving up and down repeatedly, switching positions thirty-two times (4 x 7). This expels wind from the shoulders, removes cold blood from the Jing (Well) points of both shoulders, and relieves spasm of the sinews and vessels in both axillae.
It also states: Sit in a squatting position, extend the left foot, embrace the right knee with both hands, extend the waist, inhale through the nose, and strive for seven breaths. Extend the left foot outward. This treats difficulty in flexion and extension, difficulty in bowing and rising, and pain or numbness in the shins.
Wind causing the body and extremities to be unresponsive (bu sui) occurs because body qi is deficient, cou li are open, and wind pathogenic factors injure the meridians of the Spleen and Stomach. The Foot-Taiyin Spleen Meridian is the meridian of the Spleen, which pairs with the Stomach. The Foot-Yangming Stomach Meridian is the meridian of the Stomach, known as the Sea of Water and Grain. The Spleen corresponds to the muscles of the body and assists the Stomach in digesting and transporting the essence of water and grain to nourish the body and four limbs. When Spleen qi is weak, muscles become deficient. Invaded by wind pathogens, the Spleen cannot assist the Stomach in transporting water and grain essence, leaving the four limbs and muscles without nourishment. Wind pathogens remain in the meridians, battling in the Yang meridians. Qi movement becomes sluggish, joints become lax and relaxed, causing the body and extremities to be unresponsive.
Diagnosing the Spleen pulse, if it is slow and weak, it indicates Feng Wei (Wind Atrophy), characterized by non-use of the four limbs. If the Heart and Kidney pulses are also abnormal, speech becomes difficult, the nine orifices are blocked, and the four limbs cannot be lifted. If the Kidney pulse comes excessively strong, death ensues. Treatments involving decoctions, hot compresses, acupuncture, and stone therapy have separate specific formulas. Methods for tonification, nourishment, and guiding/dispersing qi are attached below.
The "Health Preservation Formulas · Daoyin Methods" states: Vigorously shake both buttocks left and right, holding breath for nine cycles (jiu tong). This cures buttock pain and fatigue, and wind-induced unresponsiveness. Shaking the buttocks involves alternating vibrations, similar to the meaning of "Jue." During the nine breath-holding cycles, one lies prone and performs these movements, named "Toad Qi Circulation." Long-term practice cures buttock pain, fatigue, wind-induced unresponsiveness, loss of pain and itch sensation, and allows assuming various postures.
It also states: Lie supine, bring knees together, spread feet, extend the waist, inhale through the mouth, and vibrate the abdomen to the utmost extent for seven breaths. This treats high fever, pain, and unresponsiveness of the calves.
It also states: To treat pain, oppression in the four limbs, unresponsiveness, and accumulated qi in the abdomen, the bed must be flat. Lie supine with the body straight, loosen clothing belts, use a pillow three cun high, and perform Wo Gu (firm grip). Wo Gu means wrapping the thumb inside the other four fingers with each hand. Extend arms so they are five cun away from the body. Point toes upward, keeping feet five cun apart. Calm the mind and intent, harmonize the breath, do not think of other matters, focus intention on qi, and slowly perform Shu Li Quan (rinsing sweet spring/saliva). Shu Li Quan means licking lips, oral cavity, and teeth with the tongue, then swallowing saliva. Slowly exhale through the mouth and inhale through the nose into the throat. Perform gently and slowly; do not rush or force it until breath is fully harmonized. When guiding and exhaling qi, do not hear the sound of inhalation or exhalation. With each guidance of qi, mentally send it out from the toe tips. Guide qi for five or six breaths, then exhale once, counting as one respiration cycle. Gradually increase from ten breaths per cycle up to one hundred or two hundred cycles; the illness will be cured. Avoid raw vegetables, fish, and fatty meats. Do not practice qi circulation immediately after full meals or while experiencing anger, joy, worry, or resentment. Practice only in the quiet morning hours, which is excellent and can cure myriad diseases.
