Effects of Chiropractic Care on Cytokine Levels in Multiple Sclerosis

Diversified (i.e. crossed bilateral hypothenar contact) chiropractic technique will be administered at levels of identified spinal joint restriction/dysfunction (derived from thoracic spine x-rays, static and motion palpation, and confirmed or provoked localized tenderness in paraspinal soft tissues).

Sham-SM will be delivered by setting the expansion control knob on an Activator II (Activator Methods®, Phoenix AZ) device to the zero position (off; no thrust) and placed onto the dorsal thumb surface of the clinician (no actual instrument contact with study participant). At a setting of zero, no excursion of the Activator II stylus occurs, despite the device delivering an audible clicking sound, with no biomechanical force being imparted to the participant.
