I. Traditional method: Breathing exercise rehabilitation method is a method inherited and developed in traditional sports therapy. Breathing exercise rehabilitation as health care and rehabilitation, in traditional Chinese medicine has a long history, the Eastern Han Dynasty famous doctor Hua Tuo created the “five birds play” for the first Chinese body therapy, and then developed into a variety of sports therapy schools in China, passed on to the present day, the fundamental role of improving the function of all parts of the body to achieve the dredging of the tendons and ligaments, and harmonization of blood and promote the metabolism, and thus achieve the purpose of disease prevention and treatment. Its fundamental function is to improve the functions of all parts of the body, to dredge the tendons and collaterals, harmonize the qi and blood, promote metabolism, and enhance the body’s ability to resist diseases, so as to achieve the purpose of preventing and curing diseases. Ancient sports rehabilitation therapy, called sports for the guide. Guide → means to guide qi and blood; lead → the original meaning of the open bow, stretching for stretching, stretching the limbs. Therefore, guiding is a method of promoting qi and blood, stretching the limbs, and treating diseases and strengthening the limbs. It is characterized by the combination of form, intention and qi. That is, the movement of the body limbs to refine the shape, exercise breathing to refine the gas, and the intention to guide the gas shape, rehabilitation limb function recovery. Breathing operation method: by regulating the body’s internal gas, so that it is gradually gathered, stored in a certain part of the body, and gradually run along the meridian routes, in order to dredge the meridians, blood and qi. The use of inhale → exhale → stop → inhale → exhale → stop cycle after cycle, week after week, action with, consciousness training (ideas) to exclude distractions, so that the spirit into a quiet, energetic, mobilize the body’s potential ability to play the function of self-regulation, the operation of the limbs to relax, the whole breath to have slowly suck, breathing should be light, can not be rough, to be subtle, and breathing should be even.

Second, the special method: after the brachial plexus nerve injury, the use of phrenic nerve or intercostal nerve as the power nerve to repair the damaged nerve is commonly used nerve transposition surgery. After these two nerve transposition procedures, since the power nerve was originally in charge of respiratory function, postoperative functional training needs to be assisted by deep breathing. Taking phrenic nerve transposition to repair the musculocutaneous nerve as an example, the postoperative functional training method is to support the forearm of the affected limb with the healthy limb, watch the movement of the affected limb with both eyes, and try to make the affected limb complete the elbow flexion movement when inhaling deeply, if the affected limb cannot complete the movement, then visualize the elbow flexion movement of the affected limb in the brain during deep inhalation and at the same time the healthy limb will drive the affected limb to complete the movement. Repeat this for more than 2,000 times a day.
