Relationship between the proximity of each receptive field to the 4 HVLA-SM contact sites and the magnitude of paraspinal muscle spindle discharge during the manipulative thrust. Each symbol represents the mean of 16 afferents and their standard deviations. Notice that the standard deviation of the discharge for only the L7 spinous process contact site crosses 0 indicating that only this site, one segment away from the segment innervating the muscle spindles, unloaded the spindles. See Data Analysis section the Methods for description of ΔMIFduring.
