The purpose of this study is to evaluate the therapeutic effect and safety of the Balance Chiropractic Therapy(BCT) on Cervical Spondylotic Radiculopathy and to investigate the mechanism of which this efficacy is achieved.

The investigators propose a multi center randomized, parallel-controlled trial to evaluate the efficacy and safety of the balance chiropractic therapy for CSR. Participants aged 18 to 65, who are in conformity with the diagnostic criteria of CSR and the pain score regarding visual analog scales is more than 4 points and less than 8 points, will be included and randomly allocated into two groups: test group and control group. Participants in the test group will be treated with the balance chiropractic therapy, while the control group will receive the traction therapy. The primary outcome is pain severity (measured with a visual analogue scale (VAS)). Secondary outcomes will include cervical curvature (measured by Borden index), a composite of functional status(measured by Neck Disability Index ,NDI), individual patients health status(evaluated by SF-36 health survey ), and adverse events as reported in the trial.

Inclusion Criteria:

• Subjects who are in conformity with the diagnostic criteria of CSR;
• Aged between18 and 65 years old;
• The pain score regarding visual analog scales is more than 4 points and less than 8 points;
• sign the informed consent.

Exclusion Criteria:

• Subjects will be excluded if they have disorders such as vague diagnosis of acute spinal cord injury or acute spinal cord inflammation,or cervical vertigo symptom and checking for abnormal changes on transcranial doppler(TCD).
• Subjects will also be excluded if they have combined liver, kidney, hematopoietic system, endocrine system, cardiovascular system, nervous system and other severe primary disease,or fractures,osteoarticular tuberculosis, osteomyelitis, bone tumor, severe osteoporosis,or mental disabilities,
• A weak body can not withstand the stimulation of the balance chiropractic therapy .
• Individuals who have acute infectious disease, stomach or duodenal ulcer with acute perforation,or treated areas with severe skin damage or skin diseases.
• Subjects that have received surgical treatment or neck injury, or radiofrequency of cervical intervertebral disc, or minimally invasive, or ozone, or acupuncture and moxibustion, or other manipulations or block therapy within two weeks
• Lactating or pregnant patients.
• Subjects who are participating in other clinical trials related to cervical spondylosis.
