Understanding deltoid muscles in Chinese medicine with bare hands.
1. Overview of deltoid muscles.
The deltoid muscle is one of the important muscle tissues of the human shoulder, which plays a vital role in the movement and stability of the shoulder joint, and it occupies an important position in the understanding of muscles and bones in traditional Chinese medicine. Traditional Chinese medicine believes that the deltoid muscle belongs to the hand Taiyin lung meridian, which is closely related to the functions of human respiration, propaganda and other functions. In TCM freehand**, the understanding and conditioning of the deltoid muscles is also a very important part.
The deltoid muscle, commonly known as the tiger head muscle, is a deltoid muscle located under the skin of the shoulder, wrapping the shoulder joint from the front, back and outside, and is a multi-pinnate muscle. The bulging shape of the shoulder is formed by this muscle. The muscle bundle is divided into three parts: anterior, middle and posterior.
Second, the deltoid position.
Starting point: the anterior fascicle arises from the lateral half of the clavicle, the middle fascicle arises from the acromion, and the posterior fascicle arises from the scapula;
Insertion: cartoidal tuberosity of the humerus.
3. Deltoid innervation and blood supply.
Innervated nerves: innervated by axillary nerves (C4 C6) originating from the spinal brachial plexus. The axillary nerve originates from the posterior tract of the brachial plexus, passes through the quadrilateral foramen, and travels deep into the deltoid muscle around the humeral surgical neck, thus innervating deltoid activity.
Blood supply: the deltoid branch of the anterior circumflex humeral artery, the posterior circumflex brachial artery, and the thoracoacromial artery.
Fourth, deltoid function.
Contraction of the near-fixed anterior fibers allows the upper arm to flex and pronate at the shoulder joint. The contraction of the middle fibers abducts the upper arm. Posterior fibrous contraction causes the upper arm to extend and pronate at the shoulder joint. The overall contraction allows the upper arm to be abducted. In addition, this muscle has a role in strengthening and stabilizing the shoulder joint. This muscle abduction efficiency is quite low when the arm is at an angle less than 60°, while it shows the greatest contraction at angles between 90° and 180°.
5. The method of TCM freehand conditioning and understanding of deltoid muscles.
1.Visits.
In TCM manual conditioning, visiting is a very important part. By observing the shape, color, texture and other aspects of the deltoid muscle, the health of the deltoid muscle can be preliminarily judged. For example, the deltoid muscles are full and elastic, indicating healthy muscles; If you have muscle atrophy or weakened elasticity, you may have shoulder problems.
2.Palpation.
Palpation is one of the commonly used methods in Chinese medicine for freehand conditioning. Through palpation, you can understand the tension, temperature, elasticity and other indicators of the deltoid muscle, and further judge the health of the muscle. For example, if the deltoid muscle is highly tense, there may be problems such as muscle stiffness and pain; If the temperature is low, there may be problems such as poor blood circulation.
6. Abnormal appearance of non-physical and physical injury of deltoid muscle.
1.Non-physical injury: usually caused by lesions of other tissues such as nerves, blood vessels, or connective tissue. Such injuries include frozen shoulder, rotator cuff calcification, and adhesive capsulitis; As we age, muscle mass decreases, degenerative atrophy, and muscle strength deteriorates, which may lead to shoulder pain, limited mobility, and muscle weakness.
2.Physical injury: usually caused by external trauma or overuse. Such injuries include muscle strains, muscle tears, and rotator cuff injuries.
Through the understanding of deltoid muscle anatomy, you can understand that the axillary nerve is next to the quadrilateral foramen and the humeral surgical neck, so when there is quadrilateral foramen syndrome, such as edema and adhesion of the surrounding tissues of the quadrilateral foramen, shoulder dislocation and fracture of the upper end of the humerus, or even external force damage to these parts, it will cause axillary nerve injury, resulting in deltoid weakness, numbness and atrophy, and limited movement of the shoulder joint.
Regardless of the symptoms caused by physical and non-physical injuries of the deltoid muscle, the cause is often related to factors such as disharmony of qi and blood, poor meridians, etc., and there will be physical manifestations of local qi and blood stasis.
7. Daily maintenance and conditioning.
1.Maintain correct posture and avoid holding the same posture or repeating the same movement for long periods of time;
2.Pay attention to the intensity of the activity, pay attention to the weather temperature, and avoid discomfort caused by cold shoulders;
3.Moderate exercises of the shoulders and arms:
1) Stability training of the shoulder girdle: It is best to exercise the deltoid muscle first for the stability training of the entire shoulder girdle, which can avoid injury to the greatest extent during shoulder training, you can first practice doing push-ups on the wall, the feet are the same width as the shoulders, the shoulders are an arm's length away from the wall, the hands are supported on the wall, and the wall is push-ups, which can enhance the stability and control of the entire shoulder;
2) Straight arm forward raise: It is the basic action of exercising the anterior deltoid muscle, the feet are the same width as the shoulders, in a standing position, the straight arm is raised forward for 10 seconds, and repeated training;
3) Elastic band training method: stand with both feet and shoulders at the same width, step on the lower end of the elastic band, hold the upper end in your hands, pull your arms up as much as possible, and abduct 90-120 degrees is appropriate, so that the middle deltoid tract can be better trained;
4) Reverse chest clamping exercise: feet are the same width as the shoulders, arms are stretched forward 90 degrees, small dumbbells with appropriate weight are held in the hands, and both arms are horizontally abducted horizontally, so that the posterior deltoid tract can be more activated and help improve the nerve recruitment ability of the posterior deltoid tract.
It is important to pay attention during training and try to be as slow as possible to avoid injury.
4.Arrange work and rest time reasonably, avoid overwork, etc.
5.If deltoid weakness, limited shoulder joint movement, and local pain are found, joint movement should be minimized to avoid aggravating joint and muscle damage. Severe cases should go to the hospital for examination in time, and carry out joint traction, acupuncture, etc. under the guidance of a professional masseur according to the actual situation.

Complement: In Chinese medicine and modern medicine, the concept and importance of muscles and bones are different. Traditional Chinese medicine believes that muscles and bones are an important part of the human body and play a vital role in the movement and health of the body. Modern medicine, on the other hand, studies muscles and bones from the perspective of anatomy and physiology, focusing on their structure and function.
In the theory of traditional Chinese medicine, muscles and bones are one of the basic substances of the body, which are closely related to meridians, qi and blood. The main functions of muscles and bones are to support the body, maintain posture, protect internal organs, and participate in body movements. Traditional Chinese medicine believes that the health of the muscles and bones is closely related to the function of the liver, kidneys and other viscera, therefore, the method of traditional Chinese medicine to improve the muscles and bones often involves the overall conditioning.
In contrast, modern medicine has a more in-depth and scientific understanding of muscles and bones. From an anatomical point of view, muscles and bones include muscles, ligaments, joints, and other parts that work together to enable the body to perform a variety of complex movements. Modern medicine uses advanced medical imaging technology and physiological and biochemical detection methods to accurately diagnose and improve the lesions of muscles and bones. At the same time, modern medicine also pays attention to the prevention of musculoskeletal diseases, and advocates a healthy lifestyle and exercise mode to reduce the occurrence of musculoskeletal diseases.
In the manual conditioning of traditional Chinese medicine, whether it is modern medicine or traditional Chinese medicine muscles and bones, we need to conduct basic research. Dialectical treatment, flexible mastery and application, as long as it can alleviate the pain of patients, we all need to study and learn, and integrate it for our own use.
The understanding of muscles and bones in traditional Chinese medicine is of great significance for in-depth understanding of the anatomical position of the body's musculoskeletal and its physiological functions, pathological changes, and health care methods. Through acupuncture**, massage, medication**, exercise** and daily health care, it can effectively relieve the pain and discomfort of the body's muscles and bones, and restore the normal function and health of the muscles. At the same time, you can also know how to prevent and protect the muscles and bones of the body in daily life to avoid damage and pain.
