《养生方·导引法》云∶正倚壁，不息行气，从头至足止。愈疽、疝、大风、偏枯、诸
又云∶仰两足指，五息止。引腰背痹、偏枯，令人耳闻声。常行，眼耳诸根，无有挂碍
又云∶以背正倚，展两足及指，暝心，从头上引气，想以达足之十趾及足掌心，可三七
引，候掌心似受气止。盖谓上引泥丸，下达涌泉是也。
又云∶正住倚壁，不息行气，从口趣令气至头始止，治疽、痹、大风偏枯。
又云∶一足踏地，足不动，一足向侧相，转身欹势，并手尽急回，左右迭互二七，去脊
风冷、偏枯不通润。
气血两虚，风邪乘虚而入。若风邪侵犯阳分，则皮肤松弛；若侵犯阴分，则腹部拘急。柔风的症状表现为四肢无法收持控制，体内拘急且不能仰卧。
风痱的症状表现为身体没有疼痛感，四肢无法收持控制，神志清醒不乱，但一侧手臂活动不遂，这就是风痱病。如果患者还能说话，是可以治疗的；如果不能说话，则难以治愈。
风退的症状表现为四肢无法收持控制，身体疼痛，肌肉虚胀，骨节懈怠无力，腰脚软弱，感觉迟钝或丧失知觉。这是由于皮肉虚弱，不能抵御四时的虚风，导致风邪侵入分肉之间，流注于血脉之内，从而产生上述症状。如果经久不愈，就会演变成水肿病。
风偏枯（半身不遂）的成因是气血在一侧偏虚，导致腠理（皮肤毛孔及纹理）开张，受到风湿之邪侵袭。风湿客居于半身，停留在分腠之间，使气血凝滞涩少，不能滋润濡养肌肤。日久不愈，真气耗散，只有邪气独留，就形成了偏枯。其症状表现为一侧肢体不能活动，肌肉萎缩干枯，伴有轻微疼痛，言语正常，神志清醒不乱。当邪气初在分腠之间时，适宜采取温暖卧床并促使出汗的方法，补益不足的正气，削减有余的邪气，这样才可以恢复。诊察胃脉沉大、心脉小且牢急，都是偏枯病的脉象。男子发病多在左侧，女子发病多在右侧。如果不出现失音，舌头转动灵活者可以治疗，三十天后可痊愈。如果年龄不满二十岁，三年后会死亡。另外，左手尺部神门穴以后的足太阳经脉象虚弱的人，会患怕风、偏枯的病，这多由忧愁思虑所致。关于汤药热敷、针刺砭石的治疗，另有专门的方剂，此处附载补养和导引宣通的方法在后面。
《养生方·导引法》说：端正地背靠墙壁站立，闭息行气，从头部引导至足部为止。这种方法可以治愈疽病、疝气、大风病、偏枯以及诸……（原文此处似有缺漏）。
又说：仰起双脚脚趾，保持五个呼吸的时间后停止。这种方法可以牵引治疗腰背痹痛、偏枯，并能改善听力，使人耳聪目明。经常练习，可使眼、耳等感官通畅无碍。
又说：用背部端正地依靠墙壁，伸展双脚及其脚趾，静心凝神，从头部引导气息，想象将其送达足部的十个脚趾及足掌心，可连续做二十一次（三七二十一），等到感觉到掌心似乎接受了气息为止。这大概是指上引泥丸宫，下达涌泉穴的意思。
又说：端正站立背靠墙壁，闭息行气，从口部引导气息直至头部才停止，用于治疗疽病、痹证、大风病及偏枯。
又说：一只脚踏地，脚不动，另一只脚向侧面倾斜，转身呈现歪斜之势，配合双手尽量快速回旋，左右交替进行十四次（二七十四），可以去除脊背的风冷之气，治疗偏枯不通润。
When both blood and qi are deficient, wind pathogens invade simultaneously. If the wind pathogen affects the yang aspect, the skin becomes lax; if it affects the yin aspect, there is abdominal tension. The manifestation of *Roufeng* (Soft Wind) includes the inability to control the four limbs, internal tension, and an inability to lie on one's back.
The manifestation of *Fengfei* (Wind Paralysis) is characterized by a painless body, inability to control the four limbs, clear consciousness without confusion, but with unilateral arm paralysis; this condition is known as *Fengfei*. If the patient can still speak, the condition is treatable; if they cannot speak, it is untreatable.
The manifestation of *Fengtui* (Wind Retreat/Atrophy) involves the inability to control the four limbs, body pain, distension due to muscle deficiency, joint laxity, weakness in the waist and legs, and loss of sensation. This occurs because the skin and flesh are weak and unable to withstand the empty winds of the four seasons, allowing wind pathogens to invade between the muscle layers and flow into the blood vessels. If this persists without improvement, it may transform into edema (*Shuibing*).
*Fengpiangu* (Wind-induced Hemiplegia) arises from a unilateral deficiency of blood and qi, causing the *Couli* (pores and interstices) to open and become susceptible to wind-dampness. When wind-dampness lodges in half of the body, remaining between the muscle and skin layers, it causes blood and qi to stagnate and become sluggish, failing to nourish the tissues. If left untreated for a long time, the true qi dissipates, leaving only the pathogenic factor, resulting in hemiplegia. Symptoms include unilateral paralysis, atrophic and dry muscles, mild pain, normal speech, and clear consciousness. When the pathogen is initially located in the interstices, it is appropriate to lie in a warm bed to induce sweating, tonify the deficiency, and reduce the excess, thereby restoring health. Palpation revealing a deep and large stomach pulse or a small, firm, and rapid heart pulse indicates hemiplegia. In men, the onset is often on the left side; in women, on the right. If aphasia does not occur and tongue mobility is preserved, the condition is treatable, with recovery expected within thirty days. For patients under twenty years old, death may occur within three years. Furthermore, a deficiency in the pulse of the Foot Taiyang Meridian behind the *Shenmen* point at the left hand's *Cunchi* area indicates susceptibility to aversion to wind and hemiplegia, often caused by sorrow and worry. Regarding treatments using decoctions, hot compresses, acupuncture, and stone therapy, specific formulas exist separately; here, methods for nourishing and guiding/directing qi are appended below.
The *Yangsheng Fang* (Prescriptions for Nourishing Life) · *Daoyin Fa* (Guiding and Pulling Method) states: Stand upright leaning against a wall, hold the breath while circulating qi, leading it from the head down to the feet. This cures carbuncles, hernias, severe wind diseases, hemiplegia, and other... [text missing].
It also states: Extend the toes of both feet upward, holding for five breaths before stopping. This guides away bi-syndrome of the waist and back and hemiplegia, enhancing hearing so that one can hear sounds clearly. Regular practice ensures no obstruction in the sensory organs such as the eyes and ears.
It also states: Lean your back squarely against a wall, extend both feet and toes, calm the mind, and guide qi from the head, visualizing its arrival at the ten toes and the soles of the feet. Perform this seven times three (21 repetitions), stopping when the palms feel as though they have received qi. This refers to guiding qi up to the *Niwang* (Clay Pill Palace) and down to the *Yongquan* (Gushing Spring) acupoint.
It also states: Stand upright leaning against a wall, hold the breath while circulating qi, guiding it from the mouth until it reaches the head, then stop. This treats carbuncles, bi-syndrome, severe wind disease, and hemiplegia.
It also states: Place one foot flat on the ground without moving it, tilt the other foot sideways, turn the body into a slanted posture, and rotate the hands as quickly as possible. Repeat this alternating left and right fourteen times (seven times each). This dispels cold-wind from the spine and treats blockage and lack of lubrication in hemiplegia.
