Improvement After Chiropractic Care in Cervicocephalic Kinesthetic Sensibility and Subjective Pain Intensity in Patients with Nontraumatic Chronic Neck Pain

ObjectiveThe objective of this study was to examine alteration in head repositioning accuracy (HRA), range of motion, and pain intensity in patients with chronic cervical pain syndrome without a history of cervical trauma.MethodsThe study was a prospective, randomized, controlled trial. Forty-one patients with chronic cervical pain were randomly assigned to either a control group or a chiropractic treatment group. All patients were clinically examined, given general information on cervical pain, and provided with training instructions based on the clinical evaluation. The treatment included sessions with high-velocity and low-amplitude manipulation, proprioceptive neuromuscular facilitation, ischemic compression of myofascial trigger points, and spinal rehabilitation exercises aiming to normalize cervical range of motion (CROM) and HRA. Subjective pain intensity, cervical kinesthetic sensibility, and CROM were recorded before and after the study period.ResultsThere was no difference between the treatment patients and the control subjects at the beginning with regard to age, sex, subjective pain intensity, range of motion, and HRA. At the 5-week follow-up, the treatment patients showed significant reductions in pain and improvement of all HRA aspects measured whereas the control subjects did not show any reduction in pain and improvement in only one HRA aspect. No significant difference was detected in CROM.ConclusionsThe results of this study suggest that chiropractic care can be effective in influencing the complex process of proprioceptive sensibility and pain of cervical origin. Short, specific chiropractic treatment programs with proper patient information may alter the course of chronic cervical pain.
