While traction is effective in treating radiculopathy, it is less effective in treating vertebral artery, spinal cord and sympathetic cervical spondylosis. Cervical traction is a commonly used treatment for cervical spondylosis, which can stretch the narrowed cervical spinal space and reduce the pressure of intervertebral discs on the nerves and spinal canal, thus relieving the discomfort of cervical pain, radiating pain in the upper extremities, numbness, and sensory disturbances caused by neurogenic cervical spondylosis. In addition, cervical traction can rest the tense or spasmodic muscles in the neck, thus improving the discomfort symptoms such as muscle pain and stiffness on both sides of the neck. For vertebral artery-type cervical spondylosis, spinal cord-type cervical spondylosis or sympathetic cervical spondylosis, traction therapy is not very effective and can only alleviate some of the discomfort symptoms. Traction therapy for cervical spondylosis should be performed reasonably under the guidance of a physician.
