I. Wearing of protective gear 1. 2 weeks after surgery, wear shoulder and elbow sling or shoulder joint protective gear 2. 2 weeks after surgery, lift the protective gear for activities as appropriate II. Basic muscle strength exercises 1. Fist clenching exercise: active slow clenching to the limit, slow to five fingers open, do as much as possible every day. 2, deltoid isometric exercises (exercise intensity is not to cause pain): (1) isometric contraction of the anterior deltoid: the patient lies flat on the bed, under the elbow pillow. Make a fist with the affected hand, bend the elbow 90 degrees and place it immediately on the side of the body or on the plane of the scapula. While keeping the shoulder joint position immobile, the affected hand is pressed downward by the healthy hand and the affected hand is pressed upward against the healthy hand. The dorsal side of the affected elbow joint should not leave the bed. 10 seconds/each, 10-20/group. (2) Central deltoid isometric contraction exercise: The patient lies flat on the bed with a pillow under the elbow. Make a fist with the affected hand, bend the elbow 90 degrees and place it immediately on the side of the body or on the plane of the scapula. While keeping the shoulder joint position immobile, use the outer side of the affected upper arm against the wall or the healthy side to provide load to lift the affected limb outward. 10 seconds/each, 10-20 sets/group. (3) Posterior deltoid isometric contraction exercise: the patient lies flat on the bed with a pillow under the elbow. Make a fist with the affected hand, bend the elbow 90 degrees and place it immediately on the side of the body or on the plane of the scapula. While keeping the shoulder joint position immobile, hold the affected forearm with the healthy hand and press down the bed with force on the dorsal side of the affected elbow joint. 10 seconds/each, 10-20 units/group. C. Joint activities 1. 1 week after surgery (1) After 3 days after surgery, start swinging exercises, i.e. hold the affected elbow by the arm on the healthy side, bend at 90° with the back parallel to the ground, relax the arm on the affected side, and perform passive swinging of the affected shoulder back and forth and left and right, and change the direction for each direction until the angle of slight pain. 10 units/group, 2-3 groups/day. (2) In the supine position, passively move the shoulder joint in the scapular plane, with forward flexion, internal rotation and external rotation in the slightly painful range (3) Move the elbow joint and wrist joint in the full range of motion. 2. 2 weeks after surgery, start active shoulder joint movement as appropriate, with 140° of forward flexion, 40° of external rotation and 60° of abduction at 4 weeks, 160° of forward flexion, 60° of external rotation, 80° of abduction and 45° of internal rotation at 8 weeks, and basically return to normal at 12 weeks. Return to normal. Take care to avoid rotation of the upper arm in the external shoulder booth, and do not perform activities against resistance for 4 weeks after surgery.
