Abstract

A method and apparatus allows for simple correction of restricted spinal motion. The clinician applies a uniform low-energy diagnostic impulse to each vertebral segment of interest and the resulting force waveform is recorded. The force waveforms of each diagnostic impulse are compared to determine the relative compliance of each vertebral segment. The clinician then selects the vertebral segment to be adjusted on the basis of identification of fixated or hypo-mobile segments and high compliance or hyper-mobile segments. Adjusting thrusts are applied in the region of the hypo-mobile segments. The last step may or may not include a comparison of the post-adjustment compliance of the spinal system under analysis with the compliance before adjustments were performed on the spine.
