Functional exercise after breast cancer The speed of recovery from breast cancer, the implementation of further treatment and the quality of life in the long term are all related to the postoperative rehabilitation exercise and proper psychological care. Reasonable post-operative rehabilitation exercises and proper psychological care can help patients recover their physiological functions and self-confidence to the greatest extent possible, so that they can come out from the physical and psychological blows of cancer as soon as possible and devote themselves to a new life. However, modified radical surgery and breast preservation surgery will not cause dysfunction of the affected upper limb, but only the limitation of activity caused by the reduction of the affected chest and axillary skin area and scar contracture, and the obstruction of venous and lymphatic return caused by the removal of axillary vein branches and axillary lymph node dissection. These symptoms can be restored by functional exercise. The method of functional exercise is to climb the wall: stand straight with your feet apart facing the wall, put your hands on the wall at shoulder level and climb upwards, then repeat. Practice several times a day, mark the height you can climb each time, and strive to improve each exercise compared to the last. Upper limb rotation method: put the healthy arm on the backrest of the chair, put the forehead on the arm, put the affected upper limb down naturally, swing back and forth or draw a circle. When you feel the arms loosen up, you can increase the swinging amplitude or the radius of the circle until the arms loosen up. Tie the bra method: Both upper limbs are stretched out flat, then bend the elbow joints to place the hands on the back to tie the bra level. Upper limb movement method: Lie flat on the bed or floor, use a cushion or pillow at the head and shoulders, hold hands together, elbows straight, lift the upper limbs near the head, slowly lower, repeat. Shoulder Rotation: While in seated position, place your hands relaxed on your thighs, shrug your shoulders up close to your ears, then rotate your shoulders backwards and downwards while taking deep breaths. Repeat forwards and backwards the same number of times. The following exercises are slightly more complex and not mandatory. You must be sure you can do them before doing them. Pulley exercise: Put a rope on an open door, hold the door between your legs, hold the lower end of the rope with the operated hand and the higher end with the non-operated hand, pull down slowly with force on the set hand and raise the affected hand with it, repeat the exercise and try to raise the affected hand gradually until you can stretch it freely. Rope exercise: Tie a rope to the closed door handle. Grasp the end of the rope with the operated hand and rotate the entire upper extremity from the shoulder down. Vary the radius of rotation, making sure to do the same number of exercises at each radius. The radius of rotation can be changed by moving closer or further away from the door and repeating the exercise, gradually increasing the radius and number of rotations.
