Representative example of force-time plots of raw forces experienced along the y-axis by the spinal segment during SMT and passive movements (left axial rotation, extension and flexion).White line represents the loads experienced by the intact specimen; red line represents the loads experienced by the whole segment after supra- and interspinous were removed; green line after bilateral facet joints, capsules and ligamentum flavum were removed and blue line after intervertebral disc, anterior and posterior ligaments were removed.
