The diversified manipulation/adjustment entails a high-velocity, low-amplitude thrust that usually results in a cavitation of a joint. These techniques attempt to use the normal biomechanics of the spine and extremities in order to create motion in spinal or extremity joints, with the goal of restoring function and structure to the joint.
These quick, shallow thrusts may cause a popping noise often associated with the release of nitrous oxide or carbon dioxide gas within the joint.
Chiropractic doctors use only their hands to palpate specific subluxations or joint restrictions and administer precise adjustments to joints that are subluxated (fixed or hypo-mobile). By correcting these subluxations, a chiropractic physician can have a positive effect on the muscular, nervous, and immune systems.
The focus is on restoration of normal biomechanical function and correction of subluxations. In addition, diversified methods have been developed to adjust extremity joints, allowing for beneficial applications in treating sports injuries as well as numerous others.
