Range of motion testing is the backbone of most musculoskeletal VA disability ratings. The numbers measured at your compensation and pension exam determine which rating level applies under the VA Schedule for Rating Disabilities, and those numbers are only as accurate as the exam that produces them. Understanding how this testing works puts you in a position to ensure it's done correctly.
Every joint in the body has a normal range of motion defined in degrees. The VA uses these reference ranges to evaluate disability. For commonly claimed joints:
Limitation in any of these directions corresponds to a specific rating under the applicable diagnostic code.
The goniometer is a hinged angle-measuring instrument, essentially a protractor with two arms. One arm is aligned with the fixed segment (the thigh for knee measurements, the trunk for shoulder), and the other arm follows the moving segment (the lower leg, the arm) through its range.
The examiner takes measurements in active range of motion (you move the joint yourself) and sometimes passive range of motion (the examiner moves it for you). The rating is based on active range of motion, but passive motion is useful for documenting the physiological capacity of the joint independent of muscle strength or pain-limited effort.
This regulation is one of the most important and most frequently misapplied rules in VA musculoskeletal ratings. Under 38 CFR 4.59, the VA must consider painful motion as functional limitation of the joint.
In practice, this means:
If the examiner only documents your maximum range and doesn't ask about or record pain onset, the examination is incomplete. This is a common deficiency that veterans can identify and address on appeal.
Under VA regulations and M21 manual guidance, examiners are expected to assess range of motion after repetitive use, not just at initial measurement. The reason: with musculoskeletal conditions, range of motion often decreases after repeated movement (fatigability), and this worsening is part of the disability.
A complete examination includes:
If the examination report only contains a single measurement without noting whether repetitive testing was performed, and if your condition causes significant fatigability, the incomplete exam may underrate the actual disability.
Many joint conditions are characterized by flares: periods of significantly worse pain and function interspersed with more manageable baseline periods. The VA is required to account for the impact of flares on range of motion even if the veteran is not in a flare at the time of the exam.
If you're having a moderate day at your C&P exam but typically experience severe days with dramatically limited motion, say so explicitly. The examiner should document your reported worst-day range of motion limitations, and the rating should reflect that information.
When both sides of a paired joint are rated, the examiner should document each side separately with goniometric measurements. The right knee and left knee each get independent measurements. Bilateral conditions with separate ratings then benefit from the bilateral factor in combined rating calculations.
Many contracted examiners (from QTC, LHI, VES, and similar vendors) skip required exam components despite regulatory requirements. The most commonly omitted elements are painful motion documentation and repetitive use testing.
An incomplete examination is grounds for a supplemental claim or direct appeal. Specifically:
After any C&P exam, veterans have the right to request a copy of the DBQ that was completed. Compare the DBQ against the requirements described in this article. If required fields are blank or required tests are marked as "not performed," document those deficiencies in writing and reference them in any supplemental claim or Notice of Disagreement.
A thorough C&P exam for knee conditions goes beyond range of motion to include stability and meniscus testing. For shoulder conditions, strength testing and impingement signs supplement the range of motion measurements.
Flat Rate Nexus offers a free C&P exam preparation resource at flatratenexus.com/cp-exam-prep.html that covers joint exams specifically. The site also provides physician-signed independent medical opinions and a nexus letter grader to help ensure your claim documentation is complete before and after the exam.
