Movement range (or ROM ), is the linear distance or moving angle of a moving object that is properly attached to another object. This is also called the travel span (or ROT ), especially when it talks about mechanical devices and in mechanical engineering. For example, the volume adjustment key (rotary fader) may have a 300 Â ° traveling range from the "off" or muted (fully attenuated) position in the lower left, clockwise right to the right.
As used in biomedicine and by weightlifting, the range of motion refers to the distance and direction of the joints can move between the flexion position and the extended position. The act of trying to increase this distance through therapeutic exercise (range of motion therapy - stretching from flexion to extension to physiological gain) is also sometimes called the range of motion.

Measuring the range of motion
Each specific joint has a normal range of motion expressed in degrees. The reference values ​​for normal ROMs in individuals differ slightly depending on age and gender. For example, as an individual age, they usually lose a small amount of ROM.
Analog and traditional devices to measure various movements in the body joint include goniometers and inclinometers that use stationary arms, protractor, pivot, and arm movements to measure the angle of the joint axis. Because the measurement results will vary based on resistance level, two levels of motion range are recorded in many cases.
The latest technological advances in motionless technology without 3D marking allow the measurement of 26 joints of the body simultaneously, at 30 measurements per connection per second. In addition to recording more information more quickly, motion capture technology allows easy measurement of the patient's active range of motion.

Restricted motion range
Limited range of motion refers to the joint that has a reduction in its ability to move. Reduced motion may be a mechanical problem with a specific joint or may be caused by an injury or disease such as osteoarthritis, rheumatoid arthritis, or other types of arthritis. Pain, swelling, and stiffness associated with arthritis can limit the range of certain joint motions and impair the function and ability to perform normal daily activities.
Motion range exercise
Physical and occupational therapy can help improve joint function by focusing on various motion exercises. The purpose of these exercises is to gradually increase the range of motions while reducing pain, swelling, and stiffness. There are three types of motion range exercises:
- passive range of motion (or PROM ) - The therapist or equipment moves the joint through the patient's unrestricted range of motion.
- active range of motion (or AAROM ) - Patients use the muscles around the joint to do the exercises but need help from a therapist or equipment (like a rope).
- active range of motion (or AROM ) - The patient does exercises to move the joints unaided to the muscles around the joint.
