Range of motion: The full movement potential of a joint, usually its range of flexion and extension. For example, a knee might lack 10 degrees of full extension due to an injury.
Range of motion (ROM)is a measurement of the distance and direction a joint can move to its full potential. A joint is a location in the body where bones connect.The amount of movement through a normal range of motion is commonly measured in degrees using an instrument called a goniometer
