Femoral nerve paralysis

Medical records that document the degree of paralysis are central to this rating. For a 40% rating, records would need to show complete paralysis of the quadriceps extensor muscles. For the incomplete levels, exam findings that describe how severely muscle strength, sensation, or function is reduced — and how that compares to full, complete paralysis — help establish whether the picture fits severe, moderate, or mild.

Nerve conduction studies, electromyography (EMG), and physical examination findings that measure quadriceps strength and reflexes directly reflect the rating criteria. If your nerve damage affects sensation only, the regulation limits the rating to mild or, at most, moderate. Statements from you or people who know you about how the weakness or sensory loss affects your ability to walk, climb stairs, stand for periods of time, or perform work duties can help show the functional impact. If both legs are involved, records confirming bilateral involvement support combining the ratings with the bilateral factor.
