Fig. 3From: Neuromechanical response to spinal manipulation therapy: effects of a constant rate of force applicationNormalized RMS during (a) “Thrust phase” and (b) “Post-SMT1”, and (c) absolute vertebral displacements during “Thrust phase”. Muscular activity values (normalized RMS) are presented for the four applied SMT force-time profiles and all electrodes. Vertebral displacements are shown for all markers and SMT force-time profiles.* refers to p < .05Back to article page
