How VA rates lower-back motion
The General Rating Formula for Diseases and Injuries of the Spine considers motion and other findings. The illustration above covers thoracolumbar forward flexion only, not the cervical spine or a complete claim evaluation.
Listed forward-flexion criteria
| Maximum forward bend | Listed rating criterion |
|---|---|
| 30° or less | 40% |
| More than 30°, up to 60° | 20% |
| More than 60°, up to 85° | 10% |
| 90° reference | No forward-flexion percentage shown; other findings may still matter. |
The schedule rounds measured motion to the nearest five degrees. Exactly 30° is in the 40% criterion; exactly 60° is in the 20% criterion. A zero endpoint is withheld from automatic classification here because a straight pose does not establish that no movement is possible. This teaching boundary is not an exception to the rating schedule.
Other findings remain separate
Combined motion includes all six directions. Ankylosis, neurologic findings, and IVDS require their own evidence and assessment; the slider cannot diagnose or classify them. There is no separate 30% thoracolumbar forward-flexion step. Percentages in this guide are criteria, not promised outcomes.
DBQ and symptom topics to review
- Initial motion, pain and its effect on function.
- Changes after repetitions, repeated use over time, and flare-ups.
- Weakness, fatigue, endurance, walking or standing limits, and treatment.
- Leg symptoms or other neurologic concerns for qualified assessment.
What may happen in the exam room
The examiner may assess several directions of motion, strength, sensation, reflexes, and repeated movement. Testing may be modified or omitted when medically inappropriate, with an explanation. Follow the examiner's instructions and explain any difficulty accurately; do not force movement to match this illustration.
Measurements and findings to understand
Upright is the zero reference, not a disability finding. The selected example means the farthest available forward bend from upright. This generated rigid-trunk illustration does not separate hip motion from spinal motion or reproduce clinical measurement.
Questions the examiner may cover
- When did the problem begin, and how has it changed?
- Which ordinary activities are affected, and how?
- How frequent and long are flare-ups, and what changes during them?
- What treatments or supports do you use?
Functional-impact details to organize
Use your own examples of lifting, sitting, walking, sleep, and work limitations. Distinguish typical days from flare-ups. Do not adopt a symptom script or select an angle to target a percentage.
Evidence to organize before the exam
Gather relevant treatment and imaging reports, medication information, and truthful descriptions of activity limits. Do not change prescribed treatment for an exam without guidance from your healthcare provider.
Pain, repetition, and flare-ups
Pain onset and the motion endpoint are not automatically the same. The DBQ distinguishes pain from associated functional loss and asks about repeated use and flare-ups. Describe your actual experience. A clinician evaluates the evidence, estimates additional limitation when supportable, or explains why an estimate cannot be provided. Pain alone does not automatically assign 20%, and resting at home is not the same as physician-prescribed bed rest for IVDS.
How secondary service connection works
A secondary condition is not automatic. The evidence must connect a current diagnosed disability to an already service-connected condition or its medically indicated treatment.
- Basic evidence: a current diagnosis, an already service-connected primary condition, and competent evidence linking the two.
- Two theories: the primary condition or its treatment caused the new disability under 38 CFR § 3.310(a), or aggravated a pre-existing non-service-connected disability under § 3.310(b). An opinion should address both when the record raises both; causation alone may be inadequate (El-Amin).
- Treatment pathway: service-connected condition → medically indicated medication or surgery → documented adverse effect → current diagnosis. Pharmacy records, start and stop dates, and a treating clinician’s reasoning matter; medication use alone does not establish the connection.
- Weight as an intermediate step: obesity or weight gain can be part of the causal chain under VAOPGCPREC 1-2017, but obesity itself is not a disability for a VA rating.
- Standard of proof: VA applies the “at least as likely as not” standard and reasonable-doubt rule under 38 CFR § 3.102. This guide identifies evidence questions; it does not tell you what to file.
- Avoid pyramiding: 38 CFR § 4.14 prohibits rating the same manifestation twice. Mental-health diagnoses generally use one § 4.130 evaluation for the same occupational and social impairment, and insomnia may be a symptom rather than a separate disability.
- Presumptives are different: qualifying service may make chronic rhinitis, chronic sinusitis, hypertension associated with herbicide exposure, or type 2 diabetes presumptive. OSA is not a PACT Act presumptive. Check current eligibility before seeking nexus evidence for a condition the law may already presume.
- DBQ is not a nexus: a DBQ documents diagnosis and severity; it does not necessarily establish service connection. A VA-accredited VSO can help with filing strategy at no charge.
Other medically indicated treatments for a service-connected condition may support a secondary theory when a clinician documents the adverse effect in this veteran.

Possible secondary conditions to discuss with a qualified reviewer
These are educational issue-spotting notes, not medical nexus opinions. VA decides service connection.
Distinct neurologic impairment associated with the spine may be evaluated separately under the appropriate nerve code without rating the same symptoms twice.
Each affected extremity may be evaluated separately when the record identifies distinct neurologic impairment.
Associated objective neurologic abnormalities may be evaluated separately when diagnosed and linked to the spine. New loss of bladder or bowel control requires urgent medical attention.
Review when records document altered gait or weight-bearing and a clinician supports causation or aggravation of a diagnosed joint disability.
Prescribed NSAID treatment for the service-connected back condition may support a treatment pathway when records and a clinician connect it to diagnosed GERD.
Review only with a distinct diagnosis and medical reasoning addressing chronic pain or functional loss.
Reduced activity and weight gain are not enough by themselves. A clinician must support the full individualized pathway to diagnosed OSA.
Prescribed opioid treatment may be an evidence path when pharmacy records and a clinician connect it to diagnosed ED.
