Manipulation is very effective at dealing with conditions where there is a component of joint stiffness or restriction.
Manipulation involves the application of a thrust to a specific joint of the spine or extremity. An audible crack may or may not occur with such techniques & these noises occur due to the release of gases from the capsule of the joint. In some cases of back pain or neck pain, this can result in immediate relief of symptoms.
Manipulation is a powerful tool in helping to reduce pain and increase range of motion.
