The difference from traditional cervical traction: Traditional traction treatment is carried out in hospitals through traction beds or straps, which is expensive and has significant limitations on us during the treatment process. The new generation triple cervical traction device, equipped with airbag support, can watch TV, do household chores, and work from home. Difference 2 from traditional cervical traction devices: Working principle: By pushing upwards with a 20 degree arc, the intervertebral space is opened to restore the intervertebral disc that protrudes and compresses the nerve to its original position, relieving compression. It is not traditional reverse traction or straight traction. This is opposite to cervical curvature. You may feel a bit of pain, which is normal.
