Middle arm nerve group paralysis

Medical records and examination findings that document how much function you have lost in the affected arm are central to establishing the rating level. For a complete rating, records showing that you cannot or can barely perform arm adduction, abduction, rotation, elbow flexion, and wrist extension in your major or minor arm would support the highest levels. Range-of-motion measurements, muscle strength testing, and nerve conduction or electromyography studies can reflect whether the paralysis is complete or incomplete and, if incomplete, how severe it is.

For incomplete levels, objective findings such as measured weakness, reduced grip or wrist strength, and documented loss of specific movements help distinguish severe, moderate, and mild degrees. A VA or private examination that describes exactly which movements are affected and to what extent is particularly useful. Statements from you, your family, or your employer describing how arm weakness affects your ability to work, lift, carry, or perform daily tasks can help show the functional impact that corresponds to a given level of incomplete paralysis.
