The muscle that makes you hunchback with chest and head forward – trapezius muscle

The trapezius muscle is located in the upper back, originating from the external occipital prominence, the upper nuchal line, the nuchal ligament, the seventh cervical vertebra and all the spinous processes of the thoracic vertebrae. The fibers are divided into upper, middle, and lower parts, which end at the lateral 1/3 of the clavicle, the spine of the scapula, and the acromion respectively. When near fixation, the upper fibers contract to lift, rotate, and retract the scapula; the middle fibers contract to retract and rotate the scapula; the lower fibers contract to lower and rotate the scapula. When far fixed, one side is contracted to make the head bend to the same side and turn to the opposite side; both sides are contracted to make the head and spine straight. The trapezius muscle is innervated by the 11th pair of cranial nerve accessory nerves and the anterior branches of the third and fourth cervical nerves.

2. Headache, the trapezius muscle originates from the external occipital prominence, upper nuchal line, etc., especially the tension of the upper trapezius muscle will affect the fascia tension in the head area, and the activity of the trapezius muscle will affect the occipital Tissues such as nerves and accessory nerves. Therefore, when the trapezius muscle is tense, it will increase the tension of the head, compress the nerves, and cause headaches.

3. Shoulder and neck pain. When the middle trapezius muscle is injured, there will be pain in the joint between the spine and scapula, shoulder pain and weakness, and even nerve stimulation symptoms such as arm numbness and fear of cold.

4. Shoulder pain, the trapezius muscle can retract the scapula and rotate up and down during exercise, assisting the movement of the shoulder joint. When the trapezius muscle is injured, the scapula cannot be activated in time during exercise, which will cause mechanical disorder of the shoulder joint and impingement damage.

1. Trapezius muscle training, WYT activity exercises, standing position, bend your arms into a WYT shape, do the action of clamping the scapula backwards, do not extend the head forward, do each action 30 times, do 3 groups.

2. Sitting, take the left cervical spine pain as an example, sit on a stool, grasp the edge of the chair with your left hand, sink your shoulder joint, put your right hand next to your left ear, pull your head and cervical spine to the right, and feel the left side of the cervical spine Just feel stretched in the soft tissue, hold on for 30 seconds.
