The shoulder joint is one of the most flexible joints in the human body, with a range of motion close to that of the “sphere” and almost omnidirectional movement. In daily life, most of the movements need to be done with the shoulder joint, and once the shoulder joint is injured, the slight joint dysfunction may cause great inconvenience in life. 1. Shoulder anterior flexion: relax the shoulder, lift the right hand upwards with a long stick on the affected palm; 2. Shoulder abduction Take the left side as an example: relax the shoulder, lift the right hand upwards with a long stick on the affected palm. Note: When the abduction exceeds 90° and continues upward, the posture should be changed to palms upward; 3. Shoulder joint posterior extension Take the left affected side as an example: relax the shoulder, push the right hand backward with the top of the baguette on the affected side; 4. Shoulder joint external rotation Take the left affected side as an example: relax the shoulder, press the left upper arm against the side of the body while bending the elbow at 90°, hold the end of the baguette with the left hand and push the baguette to the left with the right hand. In Figure 4b, the upper arm on the affected side leaves the torso, which is a wrong posture; 5. “Behind the hand” Take the left affected side as an example: relax the shoulder, hold the end of the long stick with the left hand, and pull the stick upward with the right hand; 6. The above are some simple methods suitable for self-practice, using these methods of practice, you can achieve close to the normal level of effect, more in-depth practice methods, can only be turned to professional rehabilitation therapists.
