According to Baidu Health, cervical vertebra tractor is generally used for about 20 minutes every day for the best effect. Short time can not play an auxiliary treatment role, and long time may lead to aggravated injury. If the time is too long, it may aggravate the fatigue of the neck or reduce the stability of the cervical spine, which is unfavorable to the condition. Cervical tractor can relieve cervical muscle spasm, relieve pain symptoms and increase the height of intervertebral space and intervertebral foramen.
It should be noted that cervical traction is dangerous for patients with severe stenosis of cervical spinal canal and severe compression of spinal cord. Therefore, the cervical vertebra tractor can be used, but it needs the guidance of a professional doctor.
