Balance chiropractic therapy for cervical spondylotic radiculopathy: a randomized controlled trial

Abstract Objective. To assess the clinical effectiveness of the balance chiropractic therapy (BCT) compared with traction therapy (TT) for patients with cervical spondylotic radiculopathy. Methods: Subjects were enrolled from four hospitals. Eligible patients will be randomized to one of the two arms: the treatment group and the control group. In the treatment group, patients received the BCT for 20 days, while patients in the control group received TT. Patients visited the physician at 1- and 3-month follow-up. The primary outcome was pain severity measured with a Visual Analog Scale (VAS). Secondary outcomes included cervical curvature measured using the Borden method, a composite of functional status measured by the Neck Disability Index (NDI), patient health status (evaluated by the SF-36 health survey) and adverse events (AEs) as reported in the trial. Results: Of the 240 randomly assigned patients, 120 participants were assigned to the BCT and 120 to the TT. 231 (96.3%) provided follow-up data at 1 and 3 months. There were no significant differences in baseline data between the two groups (P > 0.05), indicating good comparability. According to the results, after BCT and TT treatment, the pain VAS score, cervical curvature, NDI scores and SF-36 scores of two groups was significantly improved (P < 0.05). Furthermore, at 20 days of treatment and 1 and 3 months of follow-up, the participants in the BCT group showed superior treatment outcomes on both primary and secondary measures. Conclusion: The BCT may be a novel strategy for the treatment of the cervical spondylotic radiculopathy. Trial registration: Clinical Trials.gov Identifier: NCT02705131.
