Figure 2: Schematic showing the experimental protocols. The protocol for a cat in the 55% body weight (BW) cohort is depicted. Contact load applied prior to the HVLA-SM removed slack from the soft tissues and engaged the L6 vertebra. The high-velocity low-amplitude spinal manipulations (HVLA-SM) were applied at the spinous process of the L6 vertebra. The 7 thrust durations were presented in random order. Duration of the contact load not drawn to scale. BW: body weight.
