Figure 2

Example of a paraspinal muscle spindle response to an Activator V mechanically-assisted manipulation (MAM) at magnitude setting of 2. Note the increase in discharge during preload and thrust delivery followed by a period of discharge cessation and subsequent return to resting discharge frequency. Time required for spindle discharge to return to 95% of baseline MIF/MF for a minimum period of 1s was 4.5 and 10.5s respectively.
