Range of motion (or ROM) is the linear or angular distance that a moving object may normally travel while properly attached to another.
The reference values for the normal ROM in individuals differ slightly depending on age and sex.
Pain, swelling, and stiffness associated with arthritis can limit the range of motion of a particular joint and impair function and the ability to perform usual daily activities.
Physical and occupational therapy can help to improve joint function by focusing on range of motion exercises.
The goal of these exercises is to gently increase range of motion while decreasing pain, swelling, and stiffness.
