How to treat lumbar disc herniation with mechanical traction?

Mechanical traction refers to traction therapy with special mechanical traction bed. Traction is often controlled by electricity or even computers, and some physical therapy is carried out at the same time. Such as automatic pulse traction therapy bed, the bed surface is divided into upper body and lower body, which can control the sliding back and forth. The upper body bed mainly controls patients to do automatic intermittent reciprocating slow traction and continuous static traction; The lower body bed surface controls the patient's lower body for pulse traction. Another example is vibrating traction bed. After 5-8 minutes of static traction, you can lift the middle section of the bed board against the patient's lumbosacral region and vibrate for 2-3 minutes, then slowly relax the traction and let the patient rest for a few minutes. Some advanced computer-controlled traction devices can adjust the traction force at any time, give an alarm when the force is too great, and can also display the changes of back muscle tension.
