Chronic pain is defined as pain that is more than three months in duration. The most common chronic pains include migraine, neck and shoulder pain, low back pain, and knee pain. The main causes of these pains are migraine, cervical spondylosis, frozen shoulder, herniated lumbar disc, knee osteoarthritis, etc. It is estimated that more than 100 million people in China are suffering from chronic pain, which seriously affects people’s quality of life and work. What causes so many people to suffer from chronic pain, especially the sharp increase in the incidence of cervical spondylosis, frozen shoulder, and herniated lumbar disc, is most often related to the reduction of human movement and abnormal body posture. Under normal circumstances, the four main weight-bearing joints of the human body: shoulder, hip, knee and ankle joints, the normal human posture is that the above joints are vertically aligned, bilaterally symmetrical and balanced, and the spine is S-shaped curved. In the modern lifestyle, people work long hours and exercise less and less. People are no longer able to maintain a straight posture, and a variety of postural obliquities have emerged as the cause of chronic pain. The traditional Chinese medicine theory considers chronic pain as a “tendon contraction”. Tendons are a concept in Chinese medicine, but in Western medicine they are collectively referred to as tendons, ligaments, tendon membranes, etc. Contraction means contraction and spasm. Simply put, tendon contraction is the shortening of the tendon, and therefore leads to the limitation of the function of the activity, when the tendon is injured and shortened, it will produce reflex contraction and spasm, long-term fixed sitting posture lack of stretching exercise, will also cause the contraction of the tendon, so that the tendon shortens day by day. Chinese medicine believes that the tendons in the human body outside the bones, muscles within; limbs and bones, contact the body, through the blood. Surrounding the body, the bones are correct tendons soft, blood to flow, couples to dense, careful way as the law, long have the life of heaven, tendons are the lifeline of our body. The biggest problem that occurs after the contraction of tendons is the deformation and misalignment of bones and joints and spine. It is often manifested as: head deviation to one side, both shoulders are not the same height, torso distortion, hip tilt, spine deflection (cervical, thoracic, lumbar vertebrae misalignment), hip joint, sacroiliac joint misalignment. Misalignment of cervical spine leads to headache, neck and shoulder pain, cervical spondylosis, frozen shoulder, etc.; misalignment of thoracic spine leads to difficulty in lifting, shoulder and back pain; misalignment of lumbar spine leads to low back pain, lumbar disc protrusion, etc.; misalignment of hip joint leads to knee pain, heel pain, etc. The tendon is one inch longer, the life span is ten years, the tendon is soft, the bone is correct, and the bone must be adjusted first. Mr. Egoscue, a famous American sports anatomist, took the lead in creating E therapy, which corrects postural abnormalities through different movements and has treated more than 18 million patients with an efficiency rate of over 90%. It is very effective in treating cervical spondylosis, frozen shoulder and herniated lumbar disc. To summarize, the effects of postural pain relief therapy are as follows: 1. Correcting bad posture; 2. Relieving and regulating chronic pain: especially pain caused by skeletal muscles, such as cervical spondylosis, herniated disc, lumbar strain, frozen shoulder and other diseases. 3, improve the function of internal organs, regulate chronic internal diseases, such as stomach pain, abdominal pain, pelvic pain, etc.
