The patient pulls on the iron bar or door frame of suitable height with both hands and hangs with both feet off the ground, using his own falling weight to produce traction, and his body can be swung back and forth. If the body is strong, strong upper limbs of patients, you can also hang the right amount of weights on both lower limbs to increase the traction. This method can be carried out 2 to 3 times a day, each time traction can be carried out for a few minutes, and then rest in bed for a few minutes, so intermittent traction 15 to 20 minutes. It is suitable for patients with lumbar spondylolisthesis such as lumbar disc herniation, lumbar slippage, acute lumbar sprain, lumbar small joint disorder and lumbar scoliosis.
