What does ROM stand for?

• A. Radius of Motion
• B. Range of Motion
• C. Range of Mobility
• D. Rate of Movement

Answer: (B)

ROM stands for Range of Motion—the amount a joint can move through its available arc, usually measured in degrees. In therapy and rehab, ROM describes how far a joint can flex, extend, abduct, adduct, and rotate, and it helps identify restrictions caused by swelling, pain, stiffness, or injury. Clinicians assess ROM to set goals, monitor progress, and decide on interventions to restore function. ROM can be active (the person moves the joint) or passive (the clinician moves it for the person). Why the other ideas don’t fit: radius of motion would imply a geometric distance from a center, not joint movement; range of mobility is a broader concept referring to overall ability to move rather than the specific angular extent of a joint; rate of movement describes how quickly a movement occurs, not how much movement is possible.
