The thoracolumbar spine DBQ is a measurement exam. Unlike the PTSD DBQ where the examiner interprets your symptoms into a tier, the back exam puts a number on the chart and the rater reads the schedule. The number that matters is forward flexion in degrees, taken with a goniometer. If the goniometer is not present, the measurement is invalid under Correia v. McDonald (2016) — this is one of the most-litigated points in the schedule, and a winnable appeal issue when it happens.
What the examiner is filling out
The DBQ (Back (Thoracolumbar Spine) Conditions Disability Benefits Questionnaire) has six sections:
- Diagnosis — the specific diagnosis (lumbar strain, IVDS, degenerative arthritis, etc.). The DC chosen depends on it (5237 / 5242 / 5243 / 5235).
- Range-of-motion measurements — forward flexion, extension, lateral flexion (left + right), rotation (left + right). All in degrees, taken with a goniometer.
- Functional loss — what causes pain, after repetitions, on flare-ups.
- Neurological component — radiculopathy in the legs (sciatica), bowel / bladder symptoms.
- Episodes of incapacitation — bed-rest prescribed by a physician. Only applies under DC 5243 (IVDS).
- Impact on occupational functioning — supports TDIU and § 4.10 functional loss.
The § 4.71a General Rating Formula for the Spine
The schedule is purely numeric. Forward flexion in degrees => tier:
Most common starting tier for service-connected back claims. Painful motion that does not limit flexion past 85° lands here.
This tier lists measured range-of-motion findings and qualifying muscle spasm or guarding.
This tier uses measured forward flexion of 30° or less or favorable ankylosis of the entire thoracolumbar spine.
The spine is fixed in flexion or extension and cannot move.
Cervical and thoracolumbar both fused. Rare.
The goniometer rule (Correia v. McDonald, 2016)
A goniometer is a hinged protractor used to measure joint angles. Range-of-motion measurements taken without one — estimated by eye, or just “ROM appears full” — are legally insufficient under Correia v. McDonald, 28 Vet. App. 158 (2016). The Court of Appeals for Veterans Claims held that:
- The exam must include both active and passive ROM.
- The exam must include weight-bearing and non-weight-bearing measurements.
- The opposite undamaged joint must be measured for comparison.
If your C&P examiner did not use a goniometer, did not test active + passive, or did not test the comparison joint, the exam is inadequate. That is grounds for a Supplemental Claim requesting a new exam under 38 CFR § 3.156(a). Mention it in your Supplemental.
The § 4.59 painful motion rule
38 CFR § 4.59 states that “the intent of the schedule is to recognize painful motion with joint or periarticular pathology as productive of disability... actually painful, unstable, or malaligned joints, due to healed injury, are entitled to at least the minimum compensable rating for the joint.”
For the spine, this means even if your flexion is full but painful, you should receive the 10% minimum compensable rating. If you have arthritis-related back pain that limits motion only slightly, do not let the examiner mark 0% — describe the pain explicitly.
Flare-ups — the DeLuca / Mitchell move
DeLuca v. Brown (1995) and Mitchell v. Shinseki (2011) require examiners to consider whether range of motion decreases during a flare-up, after repetitive use, or under weight-bearing. The DBQ specifically asks “is range of motion further limited during flare-ups?” — and if yes, by how much.
If your back gets significantly worse during flare-ups but the exam is on a good day, the examiner is supposed to estimate the flare-up flexion. If they do not, the rater is supposed to remand or seek clarification. Frame your symptoms with this in mind.
Use the criteria to understand the form
The rating schedule describes findings VA may consider. It is not a script. Describe only what is true in your own words, including frequency, duration, treatment, good and bad days, and effects on daily activities or work. Do not select or rehearse a rating tier.
The neurological component (radiculopathy)
The DBQ has a dedicated section for radiculopathy — nerve-root symptoms that travel down the leg (sciatica) from a lumbar spine condition. Radiculopathy of the lower extremities is rated separately under DC 8520 / 8521 / 8526 / 8527 per leg. You do NOT get just one rating for back + sciatica — you get the spine rating plus a separate left-leg radiculopathy rating plus a separate right-leg radiculopathy rating, all combining under § 4.25. This is one of the commonly overlooked considerations on a back claim.

DC 5243 (IVDS) — the alternative formula
If your diagnosis is intervertebral disc syndrome (IVDS, herniated / bulging disc with radiculopathy), there is a second rating path under DC 5243 based on incapacitating episodes — physician-prescribed bed rest. The rater chooses whichever formula gives the higher rating:
- 10% — at least 1 but less than 2 weeks of bed rest in past 12 months
- 20% — at least 2 but less than 4 weeks
- 40% — at least 4 but less than 6 weeks
- 60% — at least 6 weeks
The catch: the bed rest must be prescribed by a physician in the medical record. Self- imposed bed rest does not count. If you have documented prescriptions like “bed rest for 5 days” in your records, total them up across the year.

Accuracy reminder
Describe what is true in your own words, including frequency, duration, treatment, good and bad days, and effects on daily activities or work. Do not exaggerate, omit improvement, rehearse a rating tier, or guess. If something varies or you do not know, say that clearly.
