Precautions: Accidents that may occur during rehabilitation training include cardiovascular and cerebrovascular accidents, peripheral tissue injuries, delayed healing or non-healing, heterotopic ossification, unsatisfactory functional improvement, and adjustment of the treatment plan according to the specific situation. The healthy side of the program refers to the healthy side of the limb, and the affected side refers to the operated side of the limb. Joint mobility exercises should be performed once a day, and only passive exercises should be performed within 3 weeks after the surgery. Ice packs should be applied immediately after the exercises, and the ice packs should be applied for 20 minutes, and it is forbidden to repeat the exercises several times. If the swelling and pain are obvious and the fever is obvious, the ice time can be increased, and the ice can be applied every 2 hours. Under the premise of protecting the affected side of the limb, the healthy side of the limb and lower limb exercises can be carried out appropriately to prevent the body function from decreasing, accelerate the circulation of the body, and promote the recovery of the surgical localization, and the athletes should be more active in practicing. Swelling of the joints will accompany the entire exercise process, until the affected limb function is basically restored, if the pain is relieved within 30 minutes after the exercise, then the activity is tolerable range. If the swelling does not subside or increases suddenly, stop practicing immediately, increase the duration of ice packs, and seek medical advice as soon as possible. If you do not see any improvement in your exercises for 1 week after surgery, please consult your doctor immediately so as not to delay the best time for your recovery. The brace should be worn continuously for 4 weeks after surgery, placed in the 20 degree abduction, external rotation neutral position, with the affected shoulder relaxed and not dropping; it should be removed during sleep for 5-6 weeks after surgery, and worn during weekday activities. After that, the brace is gradually removed according to the review, and the shoulder is supported by sleeping in the supine position and placing a pillow or towel behind the upper arm. active activities such as excessive posterior extension, abduction touching the back and horizontal abduction are not allowed for 6-8 weeks. Progress through shrugging is not allowed (detrimental to rotator cuff healing). Active abduction and flexion are allowed only once the shoulder external rotators are adequately strengthened. at 8 weeks, low load isotonic strength training and flexibility training are performed to improve endurance. at 3 months, basic shoulder function exercises are progressively performed (anterior shoulder flexion with the aid of a pulley or an L-bar, internal and external rotation in the plane of the scapula, internal and external rotational impedance muscle exercises, abduction to 90 degrees, and horizontal abduction in a prone position). Do not over-extend the shoulder joint, do not support the weight with the affected hand, and do not move the affected shoulder suddenly for 6 weeks after surgery; avoid shrugging the shoulder and forbid lifting heavy objects during activities and exercises within 3 months after surgery. Shoulder joint activity process: 1. Lie down on the bed 2. Undo the brace 3. Move under the protection of family members 4. Wear the brace 5. Apply ice at the end of the exercise. Stage 1 (1-10 days) 1 1-6 days 1, support or triangular towel suspension 2, swinging exercises: the healthy side of the arm to support the affected elbow, bending 90 degrees back parallel to the ground, the affected side of the arm relaxation, the affected shoulder before and after the left and right passive swing, each direction of the activities to the angle of the micro-pain can be changed to the direction of the direction. 10/group, 2-3 groups/day. 3. Passive ROM a Forward flexion (tolerable range). b External/internal rotation (slight) in the plane of the scapula at an anterior inclination of 30 degrees to the coronal plane. 4, Elbow joint activity. 5, Fist clenching exercise: active slow fist clenching to the limit, slow to five fingers open, do as much as possible every day. 6, Shoulder anterior flexion, abduction, external/internal rotation, elbow flexion and other long muscle strength exercises (sub-extreme, non-painful). 7.Active assisted L-bar exercise ROM (external/internal rotation in the plane of the scapula at 30 degrees anterior to the coronal plane). 8, Cold therapy (ice every 3 hours).
