The venous thrombosis of the limbs has more causes, and active stopping, passive stopping, little or no movement of the limbs and the like are common. Active immobilization, e.g., after various surgeries, patients take active immobilization measures due to pain; passive immobilization, such as limb fracture or trauma, requires immobilization of the patient's limb to prevent aggravation of the condition; in addition, patients with severe illness, old age, weakness, and long-term bed rest often have venous thrombosis in their limbs due to little or no exercise. Therefore, in the clinical treatment process, the limbs of the patient need to be massaged to promote the venous return of the limbs and prevent the venous thrombosis of the limbs. However, improper timing of the four-limb massage, inaccurate control of massage intensity and massage cycle rhythm can lead to the formation of venous thrombosis in the four limbs.
