Background

The upper limbs bear most functions of the human body in various kinds of labor and sports, and are the parts with the highest motion fineness in a human motion system, so that fracture occurring on the upper limbs has great influence on the ability of the individual to perform labor and daily life. Moreover, once the fracture accumulates the wrist and elbow joints, the difficulty of the operation and the postoperative functional recovery increases in geometric grade. The early activity after the clinical fracture operation has very important significance, and the prognosis of the limb function in the later period of rehabilitation can be directly determined. However, after the internal fixation of the fracture is completed, the patient cannot normally perform the limb and joint movement for a long time, and in addition, the tissue is hyperplastic and sticky due to the operation trauma, the internal fixation instrument and the local inflammatory reaction, so that the muscle disuse atrophy and the joint stiffness often occur after the patient is taken out for internal fixation or the fracture is healed, the limb function is reduced, the joint mobility is reduced, the life quality of the patient is greatly reduced, and the rehabilitation exercise after the fracture of the upper limb is very important.
