Manipulation
Manipulation is a treatment technique within the practice of manual therapy. A manipulation is a passive, high velocity, low amplitude thrust applied to a joint beyond its physiological limit of motion, but within its anatomical limit, with the intent to restore optimal motion, function and /or reduce pain.

Mobilization
Mobilizations are passive movements performed by the physiotherapist on a joint in such a way that at all times these movements are within the control of the client so that he can prevent the movements if he so chooses. These movements are usually oscillatory in nature can be performed anywhere within the normal range of motion of the joint.
