All arm nerve groups paralysis

Medical records and examination findings that document the degree of lost or impaired function in the affected arm are central to this rating. For complete paralysis, records showing total loss of motor and sensory function across all nerve groups of the arm would reflect that level. For severe incomplete paralysis, findings might include marked weakness, significantly reduced grip and arm movement, and measurable sensory loss on nerve conduction or electromyography studies. Moderate incomplete paralysis might be shown by objective findings of reduced but not near-total loss of strength or sensation, along with functional limitations in daily tasks. Mild incomplete paralysis is typically shown by modest deficits on clinical exam or testing, with limited impact on function.

Statements from you or people who know you describing how the condition affects your ability to use your arm at work and in daily life can help show functional impact at each level. If the condition is purely sensory, the evidence would reflect that, and VA would limit the rating to mild or moderate. Records noting which arm is your dominant arm are also relevant, since the rating differs between the major and minor extremity.
