A method for using the postoperative rehabilitation training device for bone and joint surgery according to any one of claims 1 to 8, characterized in that: The following steps are involved: Step 1: Loosen the locking bolt (205), pull the adjustment rod (105) through the elbow support (104), and adjust the angle between the support frame (102) and the seat plate (101) and the angle between the seat plate (101) and the leg support (107); Step 2: The foot pedal (303) is stepped on to drive the first synchronous pulley (302) to rotate, and the centrifugal impeller (404) rotates to send air into the air diffuser (402), thereby promoting air flow at the second rotating shaft (501). At the same time, the second rotating shaft (501) drives the massage seat (502) to rotate, and the massage seat (502) intermittently squeezes the skin (110) to massage the patient's back.
