Muscles and ligaments are the power base for various activities in the body, and their end devices are the skeletal attachments of the muscles, which are the hubs for the transmission of force to the bones and joints, as well as the areas of stress concentration and intersection, so myofasciitis can easily develop. Myofasciitis, also known as “low back muscle injury”, “low back fibrositis”, “low back fascial pain syndrome”, etc., refers to the aseptic inflammatory reaction of muscles and fascia when the body is subjected to The acute onset of myofasciitis can be triggered when the body is stimulated by external factors such as wind and cold, fatigue, trauma or improper sleep position, etc. Acute or chronic injury or strain to the muscles, ligaments and joint capsule of the shoulder, neck and lumbar region is the basic cause of the disease. Due to the lack of thorough treatment in the acute stage and the transition to chronic; or due to repeated strain, wind and cold and other adverse stimuli, the patient can repeatedly experience chronic muscle pain, soreness and weakness, and other symptoms. Ma Hui of the Department of Orthopedics of Shanghai First Rehabilitation Hospital repeatedly injures local muscles, and when the injury heals, scars or adhesions can be left behind, and scar tissue can reduce the number or diameter of local blood vessels, resulting in a decrease in the ability to regulate local microcirculatory blood flow, which can easily lead to insufficient blood supply to the muscles and loss of anaerobic work capacity. The local ischemia of the muscles causes pain due to peripheral nerve stimulation, and the patient cannot tolerate prolonged physical activity or even sedentary activities. For example, long-term incorrect posture or psychological depression can cause physiological contracture at the level of local muscle joints, long-term repeated muscle spasm causes muscle ischemia, sterile exudation, scar formation, local myofascia is often subjected to postural load and extreme tension, fatigue causes postural injury, repeated exertion causes muscle micro-tear injury, and pain-causing substances appear around the microvascular reaction zone of myofascia. Long-term pain-sensitive points or painful myofascial nodules may form, undergoing a complex intertwined reaction process of long-term local irritation, inflammation, healing, hyperplasia or scarring, with local tissue pain and calcification of inflammatory exudate deposits and development of myoclonus. Hypoxia or lack of energy metabolism may be secondary to a decrease in local blood flow and is an important mechanism of CMPS painfulness that can cause muscle dysfunction and tissue destruction, therefore any means of improving microcirculation to the muscles and nerves even local massage or walking can provide some relief from the painful symptoms of CMPS. Pathological features of myofasciitis painful nodules: 1. a bundle of muscle fibers in a muscle surrounded by aseptic inflammatory myofibrils, stiffer. 2, A lesioned dermal nerve. 3, Hyperplastic inflammatory fatty connective tissue, closely associated with deep fascia. 4, The site where the motor nerve enters the muscle. Painful nodules mostly occur in the supraspinous ligament, interspinous ligament, posterior laminae, supraspinous muscle group, intertransverse muscle group, occipital ring fascia, levator scapulae, trapezius, rhomboid, psoas, sacrospinous, and so on. The release of local adhesions of myofascia is the basic technique to eradicate the tenderness point of MPS. The key is the mechanical destruction of the pain trigger point and not in what potion is injected, and it is advocated to let the needle tip explore repeatedly in the local area to separate the tissues and mechanically destroy the pain trigger point during injection. At present, the following can be used for MPS: saline injection at the pain point (Kawasaki therapy), which plays a role in hydrodynamic separation, steroid injection (closure therapy), which can play a role in lysing local nodal tissue, microethanol or phenol glycerin injection to separate myofascial adhesions by destroying local tissue cellular proteins, small needle knife therapy to directly cut or peel myofascial scar points, and burning of moxa on the pierced needle bar to make the needle channel The intensive warm needle therapy with the coagulation of cellular proteins and the growth of capillaries. Radiofrequency thermal coagulation therapy, which is being explored, is also similar to the intensive warm needle therapy mechanism, and is particularly suitable for myofascial release therapy in areas containing important nerves such as the neck or buttocks. Eighty-five percent of patients with chronic pain disorders have primary or secondary CMPS, such as osteoporosis, disc herniation, cervical spondylosis, posterior branch syndrome, osteoarthritis, or ankylosing spondylitis. Relief of pain in the myofascial component is an important part of the overall treatment plan, so it is important to clarify the diagnosis and plan and understand the patient before treatment begins. Elderly people or people with myofasciitis in multiple parts of the body or frail people, often accompanied by hypertension, diabetes, cardiopulmonary, cerebrovascular, mental or psychological diseases, should be planned for comprehensive treatment Radiofrequency thermal coagulation: the instrument will pass a beam of high frequency current of about 300KHZ through the electrode, so that the ionic oscillating masses in the tissue around the electrode rub against each other to generate heat, forming the required range of protein coagulation foci in the tissue and local cell destruction. destruction. We apply RF needles to reach and thermally coagulate the tender points of myofasciitis to achieve separation of tissue adhesions, release contractures and promote local tissue blood flow supply similar to intensive warm mass needles without their environmental pollution disadvantages. The radiofrequency instrument can also adjust the size and time of radiofrequency output power, precisely control the temperature, time, degree and range of thermal coagulation of local tissue heating, and can cauterize the local hyperplastic peripheral nerves. The instrument has a nerve stimulation function that can identify the nature of the tissue where the needle tip is located and the important nerves within at least 3 CM of the needle tip, which is especially suitable for treatment in myofascial areas containing important nerves such as the pear-shaped muscle area, near the intervertebral foramen and the root of the thigh. Radiofrequency thermocoagulation has some local pain after puncture, heating and treatment, and the application of analgesics is advocated for prevention and treatment. After rehabilitation, attention should be paid to educating patients to correct poor posture and strengthen muscle exercise to reduce MPS recurrence. The radiofrequency relaxation technique is flexible and controllable and can be better adapted to the specific situation of each patient, and the operation can be discontinued at any time when discomfort occurs during treatment. Therefore, radiofrequency treatment of CMPS, with the advantages of good analgesia and controllability, has shown good efficacy without serious side effects. Radiographic shock wave therapy is the current high-tech non-invasive treatment for myofasciitis pain. This technology uses the collision of high speed projectiles shot by pneumatic ballistics to produce low and medium energy shock waves, which impact the affected area several times to achieve the purpose of loosening adhesions, getting rid of calcification points, eliminating trigger points, promoting local metabolism, activating the body’s self-repair and treating chronic soft tissue pain with exact effect. Extracorporeal shock wave treatment system is a treatment device that can replace closure, injection therapy and acupuncture, with both the symptoms and the root cause, with immediate effect. This technology has the advantages of dispensing with surgery, no anesthesia, no imaging positioning, exact efficacy of 80%-95%, wide range of indications, non-invasive, easy for patients to accept, no other therapies can replace, etc., can effectively dispel the patient’s pain.
