Nerve damage in limbs (tingling, numbness, weakness) manifesting shortly after exposure
Medical records that document the degree of nerve and muscle involvement are central to supporting a rating. Nerve conduction studies and electromyography results showing the extent of nerve damage, muscle weakness, or atrophy directly tie to the criteria separating each rating level. Physical examination findings that describe whether you have any active movement below the knee, how much strength remains in the foot and lower leg, and whether muscular atrophy is present help establish whether paralysis is complete or incomplete and at what degree. For ratings in the moderate to severe incomplete range, records showing measurable muscle wasting are particularly relevant. Because wholly sensory involvement is capped at mild or moderate under the regulation, records that document motor findings alongside sensory symptoms carry more weight at the higher levels. Statements from you or people who know you describing how weakness, foot drop, or other functional losses affect your ability to walk, work, or carry out daily tasks can help show real-world impact that corresponds to the criteria at each level.
