Skeletal muscle injuries can generally be divided into two categories: acute injuries and chronic cumulative injuries, with acute injuries accounting for 70% and chronic injuries accounting for 30%. However, due to the limitations of the level of treatment and the lack of attention of patients, 50% of the 70% of acute injuries are transformed into chronic injuries. Acute musculoskeletal injuries are generally common in sports and people’s daily life, including muscle contusions, lacerations, fractures, joint dislocations and other impact injuries caused by sudden force on the skeleton and muscles. If improperly treated or not effectively rehabilitated after the injury, it can be transformed into a chronic cumulative injury. Skeletal muscle chronic cumulative injury in addition to acute injury transformation, often from the work environment, such as workers in order to complete production or other work tasks, in the labor process often need to overcome external gravity, resistance and cause chronic muscle injury. In addition, to engage in any work need to maintain a certain posture or position to overcome the gravity generated by various parts of the body, such as standing or sitting posture, the cervical spine needs to bear the load generated by the head, the lumbar spine needs to bear the load generated by various parts of the body above the waist, prolonged overload may lead to chronic cumulative skeletal muscle injury, mainly including tendonitis, nerve impingement, myofascial pain and other problems.
