Specific adjustments or manipulations are skillful manual techniques for targeted treatment of joints. They are characterized by impulses precisely controlled in terms of force, direction and location. These manoeuvres, which can be applied directly to the joint or remotely through the use of longer lever arm, are designed to be completely painless. The main goal of these techniques is to trigger a reflex effect, allowing the muscle to relax, reduce pain and restore the normal biomechanics of the joint, which can be altered by pain and pathology.
