This is a quick video x-ray of a patient with and without the Denneroll traction orthotic device.  As you can clearly see, when the patient has no support, her lordosis (neck curvature) is completely lost.  While on the orthotic, significant curvature is achieved.  Overtime, with proper use as directed by your Doctor of Chiropractic, your spine should improve using this device along with in office rehabilitative care.  This unit is suggested as an augmentation of your care, not a replacement for in office rehabilitative methods.
