The blade needle therapy is a unique method of treating chronic neck, arm, and leg pain developed on the basis of the traditional nine needles combined with acupuncture. It is a modification of the traditional acupuncture apparatus, based on Chinese medicine meridian tendon theory and modern anatomy and modern biomechanics, with soft tissue injury as the main pathological changes, the main treatment means is cutting and pulling treatment with sharp needles. In clinical practice, the use of sharpened needles for the treatment of various pain conditions has shown very satisfactory results. Theoretical basis and mechanism of action of sharpened needle therapy Combined Chinese and Western medicine sharpened needle therapy, based on Chinese medicine theory and modern medical theory of anatomy, biomechanics, spinal etiology, software tissue surgery, information medicine, peripheral nerve compression and muscle inherent peripheral mechanism as a theoretical basis with the mechanism of action of sharpened needle therapy to regulate the physiological environment of the affected area, restore the normal force balance of the fibers and improve the pain. The normal force balance of the affected area is restored and the local microcirculation is improved, so that the diseased soft tissue is reconstructed and adjusted, and the pain is then resolved. 1.Theoretical basis of acupuncture therapy 1.1 Anatomical basis Anatomy is the basis of all clinical disciplines. In acupuncture therapy, the anatomy of body surface (body markings, body projections, etc.), soft tissue level anatomy (muscle level anatomy, acupuncture level anatomy, etc.), nerve, artery and vein paths, muscle starts, stops and travels, fascia starts, stops and travels, etc. are the key contents. 1.2 Biomechanics Biomechanics is a marginal discipline that intersects and interpenetrates with biology, medicine and biomedical engineering in the last 20 to 30 years. Biomechanics is widely used in basic medical research and clinical practice of various disciplines. At the same time, it is also an important theoretical basis for acupuncture therapy, especially the biomechanics of the skeletal system, the biomechanics of joint movement, the biomechanics of soft tissues, etc., which plays an important role in solving some problems that are “known but not understood” and in improving and innovating therapeutic methods. 1.3 Spinal Etiology Spinal Etiology is a new discipline that studies a series of conditions caused by damage to the spinal cord, peripheral nerves, blood vessels and visceral nerves after damage to the spine, and treats them with chiropractic treatment. The main theoretical basis of chiropractic is the disruption of the anatomical position of the posterior spinal joints causing functional symptoms in the internal organs. Spine etiology believes that a number of disorders in combination with anatomical disorders of the posterior spinal joints can cause and aggravate symptoms, which is an important guideline for the treatment of spine-related diseases with acupuncture. 1.4 Soft Tissue Surgery Soft tissue surgery is the study of soft tissue damage (formerly called soft tissue strain) of the human motor system, such as extravertebral skeletal muscles, fascia, ligaments, joint capsule, synovial membrane, extravertebral fat or intravertebral fat, which causes pain and related signs, and is studied by surgical procedures such as extravertebral or intravertebral soft tissue release or silver needle acupuncture at intensive pressure points outside the spinal canal, or pressure points outside the spinal canal. It is a new clinical discipline that uses non-surgical treatments such as strong stimulation massage as a means of pain management (completely different from analgesic means). It is believed that the pathological basis of intra- and extradural soft tissue pain is aseptic inflammation of soft tissues due to acute injury or chronic strain; the principle of soft tissue release surgery is to release skeletal muscles and tendons outside the spinal canal, or release soft tissues with aseptic inflammation such as extradural and nerve root sheath fat inside the spinal canal. Completely blocking the conduction of their chemical stimulation to the nerve endings to achieve painlessness, as well as signs such as pain and limitation of movement caused by damaging soft tissues in the head, neck, back, shoulder, arm, lumbar, sacral, hip and leg, etc., but also complicating headache, vertigo and more than 50 other signs involving some diseases exactly similar to internal medicine, etc. 1.5 Theory of peripheral nerve entrapment Peripheral nerve entrapment is one of the main causes of pain and other discomfort in the trunk, extremities, joints and other areas. It is believed that the skeletal muscle is strengthened in both the quality and structure of the bone in order to bear a greater load in the direction of the main stress, resulting in the formation of osteophytes, as well as soft tissues in the stress concentration or the starting limit of the load, the muscle and fascia produce compensatory hyperplasia, hypertrophy or hypertrophy, in addition to tissue and functional changes, or the potential factors or direct factors causing the dermal nerve entrapment syndrome. According to the “stress concentration theory”, various factors (such as inflammatory exudation, muscle spasm, fascial contracture, etc.) cause an increase in intrafascial pressure, which, before causing ischemic contracture of the muscle, produces pathological stimulation of various nerve endings, and both the increase in fascial surface tension and the increase in intrafascial pressure can have an effect on the nerves distributed on their surface or in the interfascicular space. The theoretical basis of sharp-edged needle therapy is the “interfascial intraventricular hypertension theory”, which produces tension or compression of the dermal nerves distributed on the surface or through it. 2.1.1 Stress relief 2.1.1 Pulling stress: By cutting off a small amount of overly tense tendon fibers or cutting open the overly tense muscle membrane or tendon membrane, the abnormal attachment between tendon and bone tissue or between muscle fibers can be loosened, and the local blood vessels or nerve bundles can be isolated from the lesioned tendon fibers, so that the excessive pulling stress can be relieved and the normal force balance can be restored. 2.1.2 Extrusion stress: by cutting and releasing the soft tissues such as the injured spastic muscles around the joint, cutting the fibrous nodules of the injured muscles, cutting and releasing the nerve outlet of the tense fascia, cutting and releasing the overly tense fibers of the bone fiber canal of the tissue, relieving the excessive extrusion stress and restoring the normal force equilibrium state. 2.1.3 Internal stress: by cutting the soft tissue of sexual aseptic inflammation, cutting the fascial wax of high-pressure interfascial compartment, cutting the joint capsule of high-pressure concern cavity or high-pressure synovial bursa, decompressing and eliminating excessive internal stress, restoring the normal force balance state and improving local microcirculation. 2.1.4 Tension: tension compression of the nerve has two forms: pulling force and squeezing force. The release of excessive tension is restricted by cutting the deep fascia of tension release, fibrous connective tissue, etc.; or through the adjustment of local hydrostatic pressure and other effects, the compression of the nerve is relieved and the dynamic balance is restored, and the pain is then resolved. 2.2 Information regulating effect Fascia is a “porous medium space structure channel”, by cutting it, eliminating excessive internal stress, thus affecting the various information transmission systems and their networking effects (i.e. meridian system), so that the information transmission function of this vital information channel is restored to normal, and material and energy can be transported and utilized, so that The diseased soft tissues are reconfigured and adjusted.
