Spinal Intervention Efficacy on Correcting Cervical Vertebral Axes of Rotation and the Resulting Improvements in Pain, Disability and Psychsocial Measures

Abstract

ObjectivesMean axes of rotation [MAR] of cervical joints are an effective measure of spine pathology. Khan Kinetic Treatment [KKT] is known to relieve symptoms, but its biomechanical effects have not been quantified. This study assesses KKT efficacy using MAR correction and its associated effects.MethodsThe intervention applies vibrations via stylus to a bony landmark of the spine. Using saggital plane cervical X-rays, pre-post intervention MARs were computed for 44 patients with chronic neck pain. The study was randomized, single blinded, and sham controlled for outcome measure comparisons. Mechanical input was assessed using a load cell and vertebral acceleration and the outcome measures were: 1. cervical MARs, 2. self-reported neck pain, 3. neck disability index scores, and 4. psycho-social assessments.Results1. Average peak force on vertebrae during treatment was 10.3 N and the average peak acceleration was 2.19G, 2. KKT improved pain and neck disability scores significantly over shams, 3. KKT correct...
