Summary

Range of motion (ROM) describes how far and in what direction a joint can move. Understanding ROM helps clinicians and patients assess movement, recognize limitations, and choose appropriate exercises to support joint function.

Range of motion, or ROM, is the distance a moving object can normally travel while attached to another object. In biomechanics and strength training, ROM usually means the angular distance and direction a joint can move between flexion and extension. Flexion generally refers to bending a joint, while extension refers to straightening it.

What is joint range of motion (ROM)?
It is the angular distance and direction through which a joint can move, commonly described between positions such as flexion and extension.
What tools are traditionally used to measure joint ROM?
A goniometer or inclinometer can measure joint angles using components such as a stationary arm, protractor, fulcrum, and movement arm.
What does limited ROM mean, and what may cause it?
Limited ROM is a reduction in a joint's ability to move. It may result from a joint problem, injury, or disease such as osteoarthritis or rheumatoid arthritis; pain, swelling, and stiffness can also restrict movement.
How do PROM, AAROM, and AROM differ?
For PROM, a therapist or equipment moves the joint without patient effort. For AAROM, the patient moves using their muscles with some help. For AROM, the patient moves the joint independently using their muscles.
What is the goal of ROM exercises in therapy?
They aim to gently increase joint movement while decreasing pain, swelling, and stiffness, helping support joint function.

Quiz questions

  1. In biomechanics, what does a joint's range of motion describe?Answer: The angular distance and direction through which a joint can move.
  2. In what units is the normal range of motion for a joint typically expressed?Answer: Degrees.
  3. When measuring joint ROM, which factor can influence the value recorded?Answer: The amount of resistance applied during measurement.
  4. A patient moves a joint using their own muscles while a therapist provides some help. Which exercise type is this?Answer: Active assisted range of motion (AAROM), with patient effort and some help.
  5. Which paired terms describe restricted extension at a joint?Answer: Flexion contracture or flexion deformity.
