Previous studies testing the effects of 3-point bending types of cervical traction, have not clarified exactly what impact the sagittal cervical curve correction has on nerve root function and pain responses associated with improving an abnormal cervical lordosis in cervical spondylotic patients. The present randomized controlled trial will be undertaken to investigate the neurophysiological and pain response outcomes of 3-point bending (2-way) traction compared to standard care in patient cases with lower cervical spine CSR, chronic pain, and with a verified hypo-lordosis of the cervical spine. The primary hypothesis of this study will be that cervical lordosis restoration will have short- and long-term effects on DSSEPs and pain outcomes in CSR patients.
To test the hypothesis that improvement of cervical lordosis (CL) in cervical spondylotic radiculopathy (CSR) will improve clinical features in a population suffering from CSR. Thirty chronic lower CSR patients with CL < 25° will be included. Patients will be assigned randomly into two equal groups, study and control . Both groups will receive neck stretching and exercises and infrared; additionally the study group will receive cervical extension traction. Treatments will be applied 3 time per week for 10 weeks after which groups will be followed for 3-months and 2-years. Amplitude of dermatomal somatosensory evoked potentials (DSSEPS), Cervical lordosis, and pain scales (NRS) will be measured.
