After the humerus fracture surgery, in the early stage that is to say after the surgery, local ice is applied, and on the same day you can do hand movements, such as hand ball grip, and also forearm movements, and then a small range of motion of the shoulder joint under protection. After three days, active isometric contraction of the biceps and triceps muscles of the upper arm can be performed, with the help of the elbow shoulder and elbow joint movements can be slightly larger, and then continue with the previous hand and forearm movements. After one week, the upper limbs can be active functional exercises, active isotonic exercises and autonomous movements of the shoulder and elbow joints on their own, but the range cannot be too large. From the second week to the fourth week, the range of activities can be increased, such as shoulder shrugging, arm raising, arm abduction and washing, brushing teeth and eating. However, it is important to note that the upper arm cannot be rotated, and back scratching and bathing are not allowed. From the fourth week to the eighth week, you can do resistance training of the muscles in the axial direction to reach a completely normal range of mobility, and at the same time, you can do a little resistance. After eight weeks, that is, the recovery period, you can enter into weight-bearing exercises and resistance exercises. Of course, if there is a special case of slow healing of the fracture, it is necessary to follow the instructions of the doctor.
