Lumbosacral Strain (Lower Back)

1. What This Condition Is

Lumbosacral strain is chronic pain, stiffness, and functional limitation in the lower back caused by injury or overuse of the muscles, ligaments, and soft tissue supporting the lumbar and sacral spine. Military service is hard on the lower back: rucking, heavy lifts, parachute landings, vehicle operations over rough terrain, and sustained physical demands over years add up to lasting spinal damage. The VA rates lower back conditions based primarily on how far you can move your spine, measured at a C&P exam. If you have been told your back pain is "just strain," do not let that framing stop you from filing. Lumbosacral strain is a legitimate VA-ratable condition under Diagnostic Code 5237, and the rating criteria are tied to measurable functional loss, not a diagnosis of disc herniation or spinal stenosis.

2. VA Rating Criteria

Lumbosacral strain is rated under 38 CFR Part 4, § 4.71a, Diagnostic Code 5237. The rating follows the General Rating Formula for Diseases and Injuries of the Spine. This formula applies to both the thoracolumbar and cervical spine, but the degree measurements listed below apply specifically to the thoracolumbar (lower back) segment.

Two legal standards matter here and must be on your radar before any C&P exam.

Under DeLuca v. Brown (8 Vet. App. 202 (1995)), the VA is required to consider pain, weakness, fatigue, and incoordination on repetition when rating musculoskeletal conditions. If your range of motion worsens after you perform the movement repeatedly, the examiner must document that and factor it into the rating.

Under Mitchell v. Shinseki (25 Vet. App. 32 (2011)), flare-up severity must be considered in the rating analysis even if no flare-up occurs during the exam. If your range of motion is reduced during flares, describe this to the examiner and in your personal statement.

3. What to Expect at Your C&P Exam

The C&P examiner will measure your range of motion using a goniometer. For the thoracolumbar spine, this includes forward flexion, extension, lateral flexion (left and right), and rotation (left and right). The examiner is looking for both the total degrees of movement and whether pain occurs on movement and at what point.

After the initial range of motion measurement, the examiner should ask you to repeat the movements to test for painful motion on repetition under the DeLuca standard. If they do not do this, ask: "Are you going to test range of motion after repetition?" The answer goes in the record.

The examiner will also check for muscle spasms, tenderness, abnormal gait, and neurological symptoms including numbness, tingling, or weakness in the legs. If you have radiculopathy (nerve pain radiating down your leg), tell the examiner. Radiculopathy is separately ratable as a peripheral nerve condition and can add significant rating points.

Your job at this exam is to move only as far as you can move without pain, not as far as you think you should be able to move. Do not push through pain to appear tougher. The measurement stops where the pain stops.

Describe your worst days and your flare-up frequency. If your back locks up two days a week and you cannot get out of bed, say that specifically. The examiner rates the full range of your condition, not just what they observe in the exam room on one day.

4. Evidence You Need to Win

Service Records and STRs. Sick call visits, physical therapy referrals, limited duty assignments, and medical evacuation records from service are the foundation of the in-service incurrence element. Request your complete STRs through the National Personnel Records Center. If your back was never formally treated in service but your MOS involved sustained heavy labor or physical demands, that occupational exposure supports the nexus.

Current Medical Imaging. MRI and X-ray findings documenting the current structural condition of the lumbar spine. Degenerative disc disease, disc herniation, facet arthropathy, and spondylosis are common findings that support the diagnosis. The imaging does not need to show catastrophic damage. It needs to show current pathology consistent with your symptoms.

Nexus Letter. A letter from an orthopedic surgeon, physiatrist, or primary care physician stating "at least as likely as not" that your lumbosacral condition was caused or aggravated by military service. The letter must review your records, describe your current condition, and provide a clear rationale (Barr v. Nicholson, 21 Vet. App. 303 (2007)). The physician should address the DeLuca factors: how pain and functional loss present on repetition and during flare-ups.

DBQ Form. The relevant VA examination form is the "Spine" DBQ (VA Form 21-0960M-14). If you obtain a private orthopedic or physiatry evaluation, ask the provider to complete this DBQ. It covers all range of motion measurements, neurological findings, and functional impairment language the VA rater needs.

Personal Statement. Describe specifically how your lower back affects your daily life: inability to sit or stand for extended periods, difficulty with stairs, disrupted sleep from pain, inability to lift or carry, and how flare-ups affect your functioning. Submit as a written statement with your 21-526EZ or on VA Form 21-10210.

Buddy Statements (VA Form 21-10210). Family members, coworkers, or fellow service members who have witnessed your functional limitations can submit statements. These are especially useful if your STRs lack formal back treatment documentation.

5. Secondary Conditions to Consider

Radiculopathy (DC 8520/8620). If your lower back condition compresses or irritates the nerve roots of the sciatic or femoral nerve, the resulting leg pain, numbness, or weakness is separately ratable under the peripheral nerve schedule at 38 CFR § 4.124a. Under 38 CFR § 4.124a, DC 8521, a mild incomplete paralysis of the sciatic nerve is 10%; moderate is 20%; moderately severe is 40%; severe is 60%. File this simultaneously with the back claim. File this simultaneously with the back claim.

Hip Conditions (DC 5250-5255). Altered gait from chronic back pain places abnormal stress on the hips. Secondary hip conditions including bursitis, labral tears, and degenerative arthritis are ratable under 38 CFR § 3.310 with a medical nexus opinion.

Knee Conditions (DC 5260-5262). The same biomechanical chain applies to the knees. Abnormal load-bearing from back pain and altered gait pattern can cause or accelerate knee deterioration.

Depression and Anxiety (DC 9434/9400). Chronic pain is one of the strongest predictors of secondary depression and anxiety. A treating mental health provider can write a nexus connecting depression to the chronic pain of service-connected lumbosacral strain under 38 CFR § 3.310.

Sleep Disorders. Chronic back pain frequently disrupts sleep. If you have documented insomnia or sleep disturbance driven by your back condition, this can support a secondary claim or contribute to a sleep study for obstructive sleep apnea.

Erectile Dysfunction. For male veterans, lumbar nerve root compression at L1-S3 can directly cause erectile dysfunction. This is a neurological secondary condition, not just pain-related, and is ratable under DC 7522 with a neurological or urological nexus opinion.

6. Common Mistakes That Kill Claims

1. Moving beyond your pain limit during range of motion testing. The exam measures where pain stops your movement. If you push through pain to show you can do it, you understate your impairment and receive a lower rating. Move only to the point of pain and stop there.

2. Not describing flare-ups in your personal statement. The examiner measures you on one day. If your worst days are dramatically worse than your best day, the examiner will not know that unless you tell them. Write out your flare-up frequency, how long they last, and exactly what you cannot do during a flare. Mitchell v. Shinseki requires the VA to consider this in the rating.

3. Filing the back claim without the radiculopathy claim. If you have any leg numbness, tingling, weakness, or radiating pain, you likely have a secondary radiculopathy claim available that adds 10-40 rating points. Many veterans file only the back and leave the nerve condition on the table.

4. Not documenting in-service physical demands when there are no STR treatment records. A veteran who never went to sick call but spent four years in a physically demanding MOS still has a viable claim. Nexus letters can speak to the cumulative effect of occupational physical stress on spinal health even without contemporaneous treatment records.

5. Treating a C&P exam denial as final. If your C&P examiner's opinion is negative or inadequately reasoned, obtain a private independent medical opinion (IMO) from an orthopedic surgeon or physiatrist and file a Supplemental Claim (VA Form 20-0995). A well-reasoned IMO that addresses the negative exam's specific findings is the standard counter-strategy.

7. FWD Assist Resources

The FWD Assist HQ Back, Knee, and Joint Claims guide covers the spine rating formula in full detail, DeLuca and Mitchell documentation strategy, and how to build the evidence package for both the back condition and associated secondary nerve claims. If your back claim is part of a broader orthopedic picture, the Secondary Conditions guide covers how connected musculoskeletal claims stack under the combined ratings formula.

8. Get Help Without a Claim Shark

Free, accredited help is available through Veterans Service Organizations (VSOs) like the DAV, VFW, and American Legion, county veterans service officers, and VA-accredited agents and attorneys. Anyone charging upfront fees to help you file a VA claim violates 38 USC § 5905 and is committing a federal crime. VA-accredited attorneys and agents may only charge fees after an initial VA decision, and those fees are capped at 20% of past-due benefits. Find free accredited help at va.gov/ogc/accreditation.asp.
