Lumbosacral Strain is rated by the U.S. Department of Veterans Affairs under DC 5237 of 38 CFR § 4.71a, DC 5237 across 10 severity tiers (10% / 20% / 30% / 40% / 50%…). Service connection requires (1) a current diagnosis, (2) an in-service event, injury, or exposure, and (3) a medical nexus opinion linking the two under 38 C.F.R. § 3.303. This condition is frequently rated as secondary to Lumbar Radiculopathy or Sciatica under 38 C.F.R. § 3.310.
Lumbosacral strain is a soft-tissue injury of the lower back involving the muscles, tendons, and ligaments that support the lumbar and lumbosacral spine, producing pain, stiffness, paraspinal muscle spasm, and reduced range of motion. It is one of the most common service-connected back disabilities and frequently arises from acute overload (heavy lifting, a fall, a vehicle or parachute impact) or cumulative repetitive loading over a military career. Although the underlying strain is mechanical rather than neurologic, chronic lumbosacral strain often coexists with degenerative changes and can produce or aggravate radiculopathy that is rated separately.
Rating criteria reference 38 C.F.R. Part 4 (Schedule for Rating Disabilities). This entry has not yet undergone editorial review against the live regulation text — consult the authoritative source directly before relying on the criteria shown.
Veterans in these roles frequently file lumbar strain claims.
