Range of motion or (ROM), as used in the medical and weightlifting communities, is the achievable distance between the flexed position and the extended position of a particular joint or muscle group, or more precisely, the measurement of that distance. Also, the act of attempting to increase this distance with therapeutic exercises (range of motion therapy -- stretching from flexion to extension for physiological gain) is sometimes called range of motion. See drugs, medication, and pharmacology for substances that are used to treat patients. ...

A person who uses a wheelchair would improve the range of motion in their spine, hips, knees & ankles by using a standing frame, if possible. It is necessary that the gain in joint range be accompanied by the gain in function of the muscles which control that particular range of motion. A standing frame (also known as a stand, stander, standing technology, standing aid, standing device, standing box, tilt table) is assistive technology used by a child or adult who uses a wheelchair for mobility. ...

Measuring range of motion

As measurement results will vary by the degree of resistance, two levels of range of motion results are recorded in most cases.

1. Passive range of motion, where another person, such as a caregiver or therapist, moves the joint.
2. Active (or manual) range of motion, where the individual moves the joint themselves.
