Anterior Crural (Femoral) Nerve Paralysis
✓ VERIFIED AGAINST 38 C.F.R.§ 4.124a (Neurological conditions and convulsive disorders) · reviewed 2026-05-15 · ClaimRecon Editorial Team
Anterior Crural (Femoral) Nerve Paralysis is rated by the U.S. Department of Veterans Affairs under DC 8526 of 38 CFR § 4.124a, DC 8526 across 4 severity tiers (10% / 20% / 30% / 40%). 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.
OVERVIEW
Paralysis of the femoral nerve causing quadriceps weakness, knee extension difficulty, and anterior thigh numbness.
RATING CRITERIA (4 LEVELS)
10%
Mild incomplete paralysis of the femoral nerve — intermittent thigh paresthesia, minimal quadriceps weakness.
20%
Moderate incomplete paralysis — moderate knee-extension weakness, partial quadriceps loss.
30%
Severe incomplete paralysis — marked knee-extension weakness, frequent buckling, requires brace or cane.
40%
Complete paralysis. Verbatim § 4.124a: "paralysis of quadriceps extensor muscles."
KEY EVIDENCE TO GATHER
-Service treatment records showing injury or complaints
-Imaging (X-ray, MRI, CT)
-Range of motion measurements
-Flare-up documentation per Sharp v. Shulkin
-Buddy statements describing limitations
-Prescription history
-Physical therapy records
-Employment impact documentation
C&P EXAM TIPS (6)
1.Do NOT stretch, warm up, or take pain medication before your exam. The VA needs your baseline limitation.
2.Report your WORST day. DeLuca v. Brown requires documentation of functional loss during flare-ups.
3.Tell the examiner about flare-ups: frequency, duration, estimated ROM loss. Sharp v. Shulkin (2017) requires estimates.
4.Request active, passive, weight-bearing, and non-weight-bearing ROM testing per Correia v. McDonald (2016).
5.If you use assistive devices (brace, cane), bring them.
6.Describe daily activity impact: work, sleep, household tasks.
