Range of Motion: The Numbers That Determine Your Back, Neck, and Joint Ratings

If you've filed a claim for a joint condition, your rating likely comes down to range of motion (ROM) - how many degrees you can move. The VA uses ROM as the primary measurement for musculoskeletal disabilities under 38 CFR Part 4. A few degrees can mean the difference between a 10% and 20% rating.

How Range of Motion Testing Works at a C&P Exam

During your C&P exam, the examiner uses a goniometer to measure active range of motion (how far you can move) and passive range of motion (how far the examiner can move your joint). They'll also test for pain on movement, perform repetitive-use testing to see if ROM decreases with repeated activity, and document any flare-ups you report.

The Thoracolumbar Spine (Lower and Mid Back)

The VA measures forward flexion (bending forward), extension (leaning back), lateral flexion (side bending), and rotation (twisting). Normal forward flexion is 90 degrees.

• 10% - Forward flexion greater than 60° but not greater than 85°, or combined ROM greater than 120° but not greater than 235°
• 20% - Forward flexion greater than 30° but not greater than 60°, or combined ROM not greater than 120°
• 40% - Forward flexion of 30° or less, or favorable ankylosis of the entire thoracolumbar spine
• 50% - Unfavorable ankylosis of the entire thoracolumbar spine
• 100% - Unfavorable ankylosis of the entire spine

Combined ROM for the thoracolumbar spine means adding up all six directions of movement. Normal combined ROM is 240°. If your forward flexion doesn't hit the next threshold, your combined ROM might still get you a higher rating.

The Cervical Spine (Neck)

The cervical spine uses the same rating formula but with different thresholds. Normal forward flexion of the cervical spine is 45 degrees, and normal combined ROM is 340 degrees.

• 10% - Forward flexion greater than 30° but not greater than 40°, or combined ROM greater than 170° but not greater than 335°
• 20% - Forward flexion greater than 15° but not greater than 30°, or combined ROM not greater than 170°
• 30% - Forward flexion of 15° or less, or favorable ankylosis of the entire cervical spine
• 40% - Unfavorable ankylosis of the entire cervical spine
• 100% - Unfavorable ankylosis of the entire spine

If your spine condition involves radiculopathy - pain, numbness, or weakness radiating into a limb - that's rated separately under peripheral nerve diagnostic codes. Multiple ratings stack together, potentially resulting in a much higher overall number.

Intervertebral Disc Syndrome (IVDS)

If you have IVDS, the VA rates you under either the General Rating Formula or the Formula for Rating IVDS Based on Incapacitating Episodes - whichever is higher. An "incapacitating episode" means acute signs and symptoms requiring bed rest prescribed by a physician.

• 10% - Incapacitating episodes totaling at least 1 week but less than 2 weeks in the past 12 months
• 20% - At least 2 weeks but less than 4 weeks
• 40% - At least 4 weeks but less than 6 weeks
• 60% - At least 6 weeks in the past 12 months

The Knee

Knee claims are among the most common because the VA can rate the same knee under multiple diagnostic codes simultaneously. The two primary ROM-based codes are limitation of flexion (bending) and limitation of extension (straightening).

Limitation of Flexion (Diagnostic Code 5260):

• 0% (noncompensable) - Flexion limited to 60°
• 10% - Flexion limited to 45°
• 20% - Flexion limited to 30°
• 30% - Flexion limited to 15°

Limitation of Extension (Diagnostic Code 5261):

• 0% (noncompensable) - Extension limited to 5°
• 10% - Extension limited to 10°
• 20% - Extension limited to 15°
• 30% - Extension limited to 20°
• 40% - Extension limited to 30°
• 50% - Extension limited to 45°

A veteran can receive separate ratings for limitation of flexion and limitation of extension in the same knee. If your knee doesn't fully bend and doesn't fully straighten, make sure the examiner measures and records both.

The knee can also be rated for instability separately from any ROM limitation. If your knee gives way or you wear a brace for stability, that's rated as slight (10%), moderate (20%), or severe (30%) - and stacks with your ROM rating.

The Shoulder

Shoulder claims are rated under limitation of arm motion. The VA distinguishes between your dominant (major) and non-dominant (minor) arm. Normal shoulder flexion and abduction are both 180 degrees.

• 20% - Arm motion limited to shoulder level (90°)
• 30% (major) / 20% (minor) - Arm motion limited to roughly 45°
• 40% (major) / 30% (minor) - Arm motion limited to 25° from the side

If your shoulder ROM doesn't meet the 20% threshold, you might still qualify for 10% under a different diagnostic code if you have painful motion or documented functional loss.

The Ankle

Ankle limitation of motion uses subjective terms rather than specific degree cutoffs: 10% for moderate limitation and 20% for marked limitation. Generally, losing about half your normal ROM is moderate, and more than half is marked.

The DeLuca Factors: Why Degrees Aren't Everything

Under DeLuca v. Brown, the VA must consider functional loss beyond raw ROM numbers, including pain on movement, weakness, flare-ups, and additional loss with repetitive use.

• Pain on movement and when pain begins
• Weakened or fatiguing movement
• Additional loss of motion after repetitive use
• Flare-ups that further reduce function

Section 4.59 states that joints with documented painful motion or instability are entitled to at least the minimum compensable rating. If your ROM is technically noncompensable but you have painful motion, 4.59 can get you to 10%.

How to Prepare for Your C&P Exam

• Don't push through pain. If a movement hurts, say so and stop when pain stops you.
• Go on a bad day if you can. Your ROM varies naturally; the exam captures one snapshot.
• Describe flare-ups in detail. Frequency, duration, and functional impact matter more than vague descriptions.
• Mention repetitive-use limitations. Tell the examiner if your ROM worsens throughout the day or after activity.
• Bring a personal statement. Describe your worst days and activities you can no longer perform.

Don't Forget Secondary Conditions

Musculoskeletal conditions rarely exist alone. A service-connected back condition commonly leads to radiculopathy, hip problems from altered gait, or pain-related depression. File claims for secondary conditions with medical evidence connecting them to your primary condition.

Check What Your Rating Unlocks

Your combined rating determines which federal and state benefits you qualify for. Crossing thresholds like 30%, 50%, or 70% opens up new benefits. Use the Combined Rating Calculator to see how your rating changes, then run results through the Benefits Finder to see every benefit you qualify for.
