Myofascial injury occurs at least once in a person’s life, and the long-term pain caused by local adhesion contracture of the injured myofascia is named Myofascial Pain Syndrome (MPS). The main symptoms of MPS are neck and shoulder pain, low back and leg pain, and the unique signs of MPS are fixed pressure points and muscle tension, with a reported incidence of 30-93%. Knees, soles, neck, shoulders, elbows or wrists, etc. can occur. 2. Ischemic pain: Pain can be triggered by local cold or general fatigue, cold weather, waking up with pain during late night sleep, stiffness and pain in the morning, relieved after activity but often aggravated after long working hours or in the evening, or aggravated when inactive or overactive for a long time or even when emotionally upset. 3.Fixed pressure pain point: During physical examination, the patient is found to have tension, spasm, bulge, contracture or stiffness in one side or local muscles. The location of the pressure point is often fixed near the starting point of the muscle or the intersection of two groups of muscles in different directions, and painful hard nodes or painful muscle cords can be felt in the deep part of the pressure point. 4. There may be a history of local or adjacent injury, and the incidence is more frequent in women than in men. The diagnostic criteria for MPS in the United States are: 1. There are fixed painful areas and pressure points on the attachment points of tendons or the muscle belly. Pressing on the painful point may cause regional dispersed pain that is not distributed according to the nerve root sensation. 2.The pain worsens when the temperature decreases or when fatigue is present. 3.Treatment to increase blood flow to the muscles may reduce pain. 4.Exclude local occupying or destructive lesions. The treatment principles of MPS are: 1. de-cause: loosen soft tissue spasm and improve microcirculatory disorders; 2. improve blood supply: exercise, massage, heat therapy (infrared, laser, cupping, acupuncture) are effective but not healing, and the recurrence rate is high; 3. anti-inflammatory and analgesic: can reduce symptoms and improve the quality of life; 4. eliminate tenderness points: the application of minimally invasive techniques to loosen local adhesions can prevent recurrence and aggravation of MPS, with long term The effect is good. Minimally invasive treatment techniques include Kawasaki block for acute pain, small needle separation for those with limited pain in the chronic phase, intensive warm mass needle loosening for those with widespread pain, radiofrequency thermal coagulation loosening for dangerous areas, and so on. 5.Physical exercise: anti-gravitational muscle exercise. 6.Anti-depressant treatment: for patients who have been suffering from chronic soft tissue pain for a long time, which can lead to plant nerve dysfunction, accompanied by corresponding somatic mental symptoms.
