After a stroke, in addition to secondary prevention and psychological rehabilitation, emphasis should be placed on protecting the function of the affected limb and preventing comorbidities that can cause long-term limitation of the affected limb’s movement, such as misuse, disuse syndrome, and shoulder-hand syndrome. The key is to maintain the functional position of the affected limb and to perform appropriate passive movements. The functional position of the upper limb is the “salute position”, which means the shoulder joint is abducted 45 degrees and internally rotated 15 degrees, so that the elbow joint is level with the chest and the thumb is pointing to the nose, and the position is frequently changed to prevent deformity, and a long, light, soft object of 4-5 cm in diameter can be held in the hand. The functional position of the lower limbs is to straighten the hip joint, and a sandbag or pillow can be placed on the outside of the leg to prevent deformity of the lower limbs in abduction and external rotation; the knee joint is straightened and placed in flexion deformity; the foot should be 90 degrees from the calf to prevent foot prolapse; with the change of position, the hip joint also needs to be changed into a flexed or straightened position.
