Frozen shoulder, known as periarthritis, is a chronic aseptic inflammation of the joint capsule and soft tissues surrounding the shoulder joint caused by injury and degeneration of the muscles, ligaments, tendons, bursa, and joint capsule (rotator cuff). It starts slowly and has a long course. Since women around 50 years old are prone to this disease, it is also called “fifty shoulder”; “frozen shoulder” is an image of shoulder joint pain, followed by movement disorders; in patients with frozen shoulder, they feel cold air entering and leaving their shoulders, so they are also called In patients with frozen shoulder, they feel cold air coming in and out of their shoulders, so they are also called “Leaky shoulder wind”; there are also patients who call it “combing head wind” and so on. Frozen shoulder is characterized by widespread pain, functional limitation and pressure pain. The pain in the shoulder can be paroxysmal or persistent. In the acute stage, the pain is severe, aggravated at night, and can occur with activity and rest. In some patients, the pain may radiate to the forearm or neck (cervical cervical spondylosis). The shoulder joint movement is limited, especially abduction, external rotation, and posterior extension, and in severe cases, the patient cannot brush his teeth, wash his face, comb his hair, take off his clothes, or insert his coat pocket, and even local muscle atrophy. The formation of frozen shoulder has two factors: internal and external. Internal factors are old age and weakness, liver and kidney deficiency, deficiency of qi and blood, i.e. aging and degeneration of the rotator cuff resulting in the accumulation of local metabolites, which stimulate the peripheral nerves and produce pain and muscle contracture (aseptic inflammation). External causes are wind, cold and dampness, trauma and chronic strain injury. In addition, fractures and dislocations of the shoulder, fractures of the arm or forearm, which are fixed for too long or during the fixation period without paying attention to the functional exercise of the shoulder joint, result in pain and functional limitation of the shoulder joint. At present, a large amount of data and statistics show that the risk factors leading to frozen shoulder are related to cold/injury/static/old/. The aseptic inflammation and edema produced by frozen shoulder can be absorbed and the pain relieved by medication and other methods. However, adhesions of the surrounding tissues can only be loosened by functional exercises after the acute phase. Therefore, medication and functional exercise are equally important in the treatment of frozen shoulder. Functional exercise for frozen shoulder: 1. Front and back swing exercise: Bend your torso forward (i.e. bend over), drop your upper limbs, try to relax the muscles and ligaments around the shoulder joint, and then do the front and back swing exercise, the amplitude can be gradually increased, 30-50 times. At this point, record the swing time, then straighten the waist and take a short rest. After resting, do the swinging exercise holding a heavy object (0.5-2 kg) and swing it back and forth for the same amount of time (30-50 times), so as not to produce pain or induce muscle spasm. At the beginning, the weights held should not be too heavy. You can start with 0.5 kg, then gradually add up to 1 kg, and slowly add up to 2 kg. 2.Circle exercise: The patient bends down and hangs his arm, flings the affected arm, and does a circle exercise from the inside to the outside or from the outside to the inside with the shoulder as the center, using the flinging of the arm to drive the shoulder joint activity. Repeat from small to large amplitude for 30 to 50 times. 3. Climb the wall with both hands: stand facing the wall, lift both hands upward, hold them on the wall, and slowly climb upward along the wall with both fingers, so that both upper limbs are raised as high as possible, and when the maximum is reached, make a mark on the wall, and then slowly return downward to the original place. Repeatedly, gradually increase the height. 4.Lateral one-handed wall climbing: The patient stands sideways to the wall and slowly climbs upward along the wall with the fingers of the affected side to raise the upper limbs as high as possible to the maximum, make a mark on the wall, and then slowly go back down to the original place, repeatedly, gradually increasing the height. 5.Shoulder induction and abduction: The patient lies on his back, crosses the fingers of both hands, palms up, puts them on the back of the head (occipital), first makes the two elbows inward as much as possible, and then abducts them as much as possible. 6.Pull the slide. 7, combing the hair: the patient can stand or lie on his back, with the affected elbow flexed, and make combing movements. 8.Towel pulling behind: take a long towel, pull one end with each hand, put it behind the body, one hand on top, one hand on the bottom, and pull it like rubbing. At the beginning of the activity, the patient may have some restrictions, but do not rush, the action slowly from small to large, and feel better and better. If you keep doing this several times a day, the condition of frozen shoulder will gradually improve. See above 9. Functional exercise with the help of apparatus: With the help of general apparatus is beneficial to strengthen the intensity of functional exercise. However, you should not use violence to avoid unnecessary soft tissue injury. Auxiliary equipment available household items or sports equipment, of course, can also be artificial help. Posterior hand pulling exercise: hands backward, from the healthy side of the hand pulling the affected wrist, gradually pulling upward, repeatedly. This exercise helps the affected limb to recover from internal rotation. 10.Drawing circles on the wall: Patients face the wall, straighten their arms and symbolically make circles on the wall. Repeat it often, it will be very beneficial to the recovery of frozen shoulder.
