In HVLA, the aim is to deliver a quick, controlled thrust that overcomes the restrictive barrier—this is the limit to motion caused by soft tissue tension and joint mechanics in a dysfunction. By moving through that restrictive barrier, the joint can regain its normal, more accessible range of motion. You don’t push to the anatomic barrier, which is the hard end of the true anatomical motion, and you don’t stop at the barrier itself. Moving through the restrictive barrier restores mobility without crossing into unsafe end ranges. That’s why the best choice is to move through the restrictive barrier.
