Painful Motion & Functional Loss

Where a joint is actually painful, § 4.59 can support the minimum compensable rating under the diagnostic code that applies to that joint, even if your measured range of motion is technically "normal." (see 38 CFR § 4.59)

This is one of the most overlooked regulations in the rating system, and also one of the most over-promised. Two limits matter. First, § 4.59 is applied together with the assigned diagnostic code: it can bring you up to that code's minimum compensable level when the measured motion would not get you there on its own, but it does not create a free-standing 10 percent rating, and where a code provides no compensable evaluation there is no minimum for it to unlock (Sowers v. McDonald, 2016). Second, pain matters because of what it does: under Mitchell v. Shinseki (2011), pain can cause functional loss, but pain by itself is not functional loss. So "my joint hurts" is the beginning of the analysis, not the end of it.

When rating musculoskeletal conditions, the VA must consider these factors, collectively known as the "DeLuca factors" (DeLuca v. Brown, 1995):

Disability ratings for musculoskeletal conditions must reflect the actual functional impairment, not just the diagnostic label or range of motion measurement. (see 38 CFR § 4.40)

Functional loss includes:

• Inability to perform normal working movements with normal excursion, strength, speed, coordination, and endurance
• Loss of power, weakness, lowered threshold of fatigue, and pain
• Less movement than normal, more movement than normal (instability), weakened movement, excess fatigability, incoordination
• Swelling, deformity, atrophy of disuse
• Disturbance of locomotion and interference with sitting, standing, and weight-bearing

The VA has specific requirements for how ROM must be tested. If these aren't followed, the exam may be inadequate:

• Active and passive ROM: The examiner must test both. Active = you move the joint yourself. Passive = the examiner moves it. The difference matters. Passive ROM is often better than active, and both should be recorded.
• Weight-bearing and non-weight-bearing: For applicable joints (knees, ankles, hips), ROM must be tested both with and without weight-bearing. Walking ROM is different from sitting ROM.
• Pain onset notation: The examiner should note the degree at which pain begins during motion, not just the endpoint, because that is where the analysis of functional loss starts under §§ 4.40, 4.45 and 4.59.
• Repetitive use testing: At least 3 repetitions must be performed and any additional loss noted. If additional loss can't be tested during the exam (e.g., because flare-ups aren't occurring), the examiner must provide an estimate.
• Opposite (undamaged) joint: For comparison purposes, the examiner should test the opposite joint when applicable.

Flare-ups are periods when your condition is significantly worse than baseline. The VA must consider flare-ups when assigning your rating.

What the Examiner Must Do

• Ask about flare-ups, frequency, duration, severity, and what triggers them
• Estimate additional functional loss during flare-ups, expressed in degrees of additional ROM loss if possible
• An inability to estimate has to be explained. Under Sharp v. Shulkin (2017), before concluding that flare-up loss cannot be estimated without speculation, the examiner must elicit the relevant information from the veteran and consider the procurable medical evidence, and the explanation must rest on the limits of medical knowledge generally rather than on the flare-up not happening during the appointment or on the examiner's own reluctance.

How to Document Flare-Ups

• Keep a symptom diary. Track good days vs bad days, what triggers flare-ups, how long they last, and what you can't do during them.
• Photograph swelling or visible changes during flare-ups if applicable.
• Get medical records during flare-ups. If possible, see your doctor during an actual flare-up so there's a contemporaneous medical record documenting the severity.
• Buddy statements. Have family or coworkers describe what you're like during flare-ups vs normal days.

A 2017 Court of Appeals for Veterans Claims decision changed flare-up evaluations significantly (Sharp v. Shulkin):

• Examiners can't dodge the flare-up question. Before Sharp, many examiners wrote "I can't estimate additional loss during flare-ups without resorting to mere speculation." The court ruled this is not acceptable without a thorough explanation of why.
• The examiner must do their best to estimate. They should consider the veteran's description, frequency, severity, and functional impact of flare-ups and provide their best medical estimate of additional ROM loss.
• If the exam doesn't happen during a flare-up (most don't), the examiner must still account for flare-ups based on all available evidence.

• Report your movement honestly, in both directions. Move as far as you actually can and stop where pain actually stops you. Do not force past that point to look stoic, and do not hold back short of it. An accurate measurement is the goal; the record is only as good as what it reflects.
• Describe your typical day and your worst periods. Both matter, and specifics beat adjectives: "on bad days I cannot bend the knee past about 45 degrees and I use a cane" tells the examiner more than "it hurts sometimes."
• Say how often flare-ups happen and how long they last, and what you cannot do during them. This is the information the examiner is required to gather under Sharp, and you are the only source for it.
• Describe what happens with repeated use. "Fine for the first few steps, but after about ten minutes of walking the knee buckles" is the kind of detail the §§ 4.40 and 4.45 analysis turns on.
• Bring and mention assistive devices. If you use a brace, cane, or walker, even only sometimes, bring it and say when you use it.
• Tell the examiner about treatment and medication truthfully, including anything you took that day. Whether you are measured medicated or unmedicated changes what the numbers mean, so the examiner needs to know which one they recorded.
• Answer questions about other causes truthfully too. If you do not know why something hurts, saying so is accurate and is better than guessing.
• It is fair to ask what was tested, such as whether motion was measured actively and passively, or with weight-bearing where that applies. Knowing what the report will and will not contain helps you see what evidence is still missing.

A C&P exam that does not fully capture painful motion, flare-ups, and repetitive-use loss creates a record that can work against a veteran at a future rating action. Under 38 CFR § 4.59, the compensable rating standard is tied to painful motion, not just measurable motion. If an exam records a range of motion number without noting the degree at which pain begins, that number becomes part of the claims file under 38 CFR § 4.2, which directs every subsequent rater to reconcile the "whole recorded history."

The Reduction Standard

VA may propose a rating reduction when evidence shows "material improvement" under actual working or living conditions. The comparison baseline is the prior exam. A prior exam that recorded full or near-full range of motion without documenting pain onset, flare-up loss, or repetitive-use loss under the DeLuca factors (DeLuca v. Brown, 8 Vet. App. 202 (1995)) and Correia v. McDonald, 28 Vet. App. 158 (2016) establishes a baseline that may not reflect the veteran's actual functional level at the time it was taken.

If a later exam is conducted by an examiner following the full 38 CFR §§ 4.40 and 4.45 standard and records a different picture, the two exams may appear inconsistent in ways the record does not explain.

Flare-Up Loss Must Be a Number

An examination that happens on a good day is still expected to address flare-ups. Sharp v. Shulkin (2017) requires the examiner to elicit the veteran's own description of flare-ups and to consider the procurable medical evidence, and to estimate additional functional loss where that evidence allows, using clinical judgment rather than declining simply because the flare-up was not observable at the appointment. Where an estimate genuinely cannot be made, the reason has to be explained on that basis. A report that records only "veteran reports flare-ups" and stops has not done that work.
