The present technology is an assembly for providing a highly repeatable, and accurate repetitive impulse with a force of about 0.5 N to about 16 N with a Z-axis of acceleration (shear acceleration) of about .5 g to about 5g at about 5 Hertz (Hz) to about 200 Hertz. This can be exerted in the vicinity of a spinal vertebrae, including an intervertebral dise. The assembly allows for precise alignment of the patient, precise alignment of the treatment stylus and precise treatment, thereby ensuring a highly accurate and repeatable treatment.Treatment conditions can be varied depending upon the size of the patient, which includes human and veterinary patients. The method is non-invasive.
