Joint manipulation is the passive mobilization of synovial joints in an effort to achieve a therapeutic effect. Effects include temporary relaxation of surrounding muscle and intra-joint pressure. This consequently can increase passive range of motion of the targeted synovial joints. With a high-velocity low-amplitude force, the capsule of a joint (containing synovial fluid) can be deformed causing a change in pressure within the joint space. The effects are temporary though positive and can allow for freer less painful motion during therapeutic exercise.
