【正文】 raction, massage instrument is the classification decline, such as ordinary traction beds are modified, the installation vibrator and heat resistance, they could achieve massage, hammering, heat treatment function。t do this. 6 Cervical vertebra traction of the main conservative therapy and curative effect of really a method, the treatment effect through the following aspects to achieve: 1 limit cervical activities, reduce the pressure of the spinal cord and the nerve roots rubbing and undesirable stimulation, help to spinal cord, nerve root, the joint capsule, muscle groups such as the swelling and inflammation subsidise. 2 and increase vertebral clearance and between vertebra hole, reduce or even remove nerve root by stimulating and oppression. 3 relieve muscle spasms, and restore the balance of cervical spine, reduce the pressure inside the intervertebral disc, buffer disc around to pressure. 4 small and open joint space, remove synovial embedded meal, and restore the normal sequence between vertebra and relationship. 5 make the distortion in the sudden between holes of vertebral artery to unbend, improve the vertebral artery blood supply. 6 and the longitudinal diameter cervical stretched, spinal cord extend, yellow ligament knit recruit flat, the spinal canal relative increase volume. The drawing of the right treatment not only remove muscle spasms, and at the same time also can improve the nerve root stimulating symptoms. But traction treatment of all of the cervical spine is not great benefit to no harm, it also has his range. 1. The traction is mainly used in the following types of cervical vertebra disease: (1) on cervical spondylosis of nerve root type: especially for vertebral instability caused by day spinal nerve root stimulating symptoms。t insist, in addition, when during the course of 9 treatment or when suddenly stop traction, some patients will appear giddy wait for a symptom aggravating, this may be influence the effects of a main reason. Lie a traction, because the patient supine is empty and traction than hard bed foot of the bed into a certain level Angle (about level 30 degrees) lie a position not easy change, the neck position and sleep position is consistent, neck good fixed difficult deformation, fortable fortable feeling. At the same time, this method except neck gravity traction outside, the body downwards gravity also have to drag the effect, therefore is twoway stretch form. Traction was finished, patients can be in bed for a little rest, reduce suddenly traction end vertebral tendon reply caused disfort, patients can insist to plete treatment time. The method to seat the effect of both traction, and reduce the traction of side effects of purpose. In the two groups were in horizontal contrast curative effect of up to %. Based on this, medical instruments, designed to horizontal will achieve better results.
