1 (joint mobility) The ease with which an articulation, or series of articulations, is able to move before being restricted by surrounding structures. Mobility is difficult to measure. Sometimes measurements of the end-position achieved by the extremity of a limb or limb-segment are used to reflect mobility, but these measurements are dependent. on the positional relationships of other segments of the body. See also active mobility exercise, passive mobility exercise.
