Neck, shoulder, lumbar and leg pain is a common and frequent disease in the middle-aged and elderly population, seriously troubling the life of middle-aged and elderly people. The most common causes are degenerative changes in the body with age, long-term ambulatory work and improper work-life posture, and untimely or inappropriate treatment after acute injury. After the onset of the disease, the patient’s condition often recurs and is difficult to heal, causing great inconvenience and pain to the patient’s working life. At present, there are various clinical treatments for neck, shoulder, back and leg pain, including Chinese and Western medicine, physical therapy, acupuncture, cupping, gua sha, and even surgery, all of which are effective but prone to recurrence. Acupuncture, which was born in the 1970s, has the advantages of being less painful, more effective and less prone to recurrence, and has become a latecomer in the clinical treatment of neck, shoulder, waist and leg pain. The emergence of acupuncture has changed the previous understanding and treatment of neck, shoulder, back and leg pain, and has relieved the pain of most patients suffering from neck, shoulder, back and leg pain. It not only inherits the advantages of traditional acupuncture therapy, such as minimally invasive, less painful and economical, but also absorbs the latest research progress of modern medicine, and cleverly grafted the scalpel of modern medicine onto the acupuncture needles, so that the “scalpel”, with the help of acupuncture needles, can be used to treat neck, shoulder, back and leg pain. With the help of acupuncture needles, the “scalpel” can penetrate deeper into the body through the needle holes of less than 1mm on the body surface to carry out targeted relaxation treatment, which improves the precision and targeting of treatment and achieves good clinical treatment results. Acupuncture and knife therapy is a new treatment combining Chinese and Western medicine, which integrates acupuncture and moxibustion “needle” and western medicine “knife”. The famous acupuncturist Professor Wang Xuedai has praised the acupuncture knife therapy: acupuncture knife medicine is the product of the interpenetration of the two kinds of medicine, is one of the successful examples of modernization of Chinese medicine. For neck, shoulder, waist and leg pain, acupuncture medicine creatively put forward the theory of soft tissue dynamic and static balance imbalance. As we all know, the reason why our human body can complete various complex movements depends on the normal function structure of our muscles, ligaments and their attached bursa, tendon sheath, fascia and other soft tissues, and the normal function structure of all soft tissues to maintain the normal functional activities of the human body under static and dynamic conditions is called dynamic and static balance. Once the soft tissues of the human body become diseased for various reasons, such as inflammation, adhesions, contractures, scarring, and local circulation disorders, resulting in the soft tissues not being able to play their normal physiological role, it is called dynamic and static balance disorders. Acupuncture treatment focuses on these soft tissue lesions, loosens local adhesions, scars and contractures, and through minimally invasive stimulation, promotes the improvement of local circulation, accelerates the metabolism of local pathological products and the dissipation and absorption of inflammation, thus restoring the dynamic and static balance of soft tissues and achieving the purpose of treating neck, shoulder, back and leg pain. After more than 40 years of clinical verification, the efficiency of acupuncture treatment for neck, shoulder, lumbar and leg pain can reach more than 80-90%, and the recurrence rate is low, so it is a new choice for patients with neck, shoulder, lumbar and leg pain.
