<unk>  (or<unk> , is the linear or angular distance that a moving object may normally travel while properly attached to another. It is also called range of travel (or ROT), particularly when talking about mechanical devices and in mechanical engineering fields. For example, a sound volume control knob. As used in the biomedical field and by weightlifters,<unk>  refers to the distance and direction a joint can move between the flexed position and the extended position. The act of attempting to increase this distance through therapeutic exercises<unk>  therapy—stretching from flexion to extension for physiological gain) is also sometimes called<unk> .
