A healthy shoulder joint is an important guarantee of upper limb function. Shoulder trauma and disease are often associated with pain, swelling, and limited movement, and in severe cases, secondary adhesions and rotator cuff injury may cause irreversible disability of the shoulder joint. The principle of rehabilitation training is to start early, from passive to active, step by step, and persistently. 1.Pendulum exercise: Stand with the trunk slightly bent forward, hold the table with the other hand, and move the affected limb back and forth, left and right, and in a circle. 2.Shoulder blade exercise: standing or sitting, hands hanging naturally, shrugging shoulders, retraction, internal and external activities bilaterally. 3.Tabletop sliding and stretching: sitting at the table, forearm on the edge of the table and elbow joint slightly flexed, bend over so that the forearm along the edge of the table sliding forward. 4.Squatting on the table: stand with your back to the table, grab the edge of the table with your fingers facing forward, and squat with your elbow flexed and shoulder extended back. 5.Side sliding extension: sitting on the edge of the table, arm on the table, palm facing up, sliding arm across the table, head towards the direction of arm movement. 6.Internal rotation exercise: lying down, shoulder joint forward flexion 90° elbow joint flexion 90°, one hand holding the affected wrist downward; external rotation exercise: standing, the affected upper arm clamping the body, elbow joint flexion 90° against the wall, moving forward. 7.Posterior extension to touch the back: standing or sitting, shoulder up to touch the back, then shoulder back to touch the back. 8.Isometric contraction exercise: standing facing the wall, shoulder joint forward flexion against the wall, continuous force, the joint remains immobile; affected side to the wall, shoulder joint abduction against the wall, continuous force, the joint remains immobile; affected side to the wall, arm clenching, elbow joint flexion 90°, pushing outward against the wall, keeping the joint immobile. 9, resistance training: standing, one end of the elastic band on the soles of the feet, hand holding the other end, for forward bending and abduction movements; double upper arm clamping body, double elbow flexion 90 °, hands holding the elastic band to pull; hands holding both sides of the elastic band for chest expansion exercise.
