Why Perform NCV Studies and EMG Test?

• Required AMA Guides to the evaluation of permanent impairment, 6th edition:
• “The diagnosis of a focal neuropathy syndrome must be documented by sensory and motor nerve conduction studies (NCV) and/or needle EMG in order to be ratable as impairment.”
• At Present, only the needle EMG is considered diagnostic of radiculopathy.”
• NCV/EMG Evidence can add 9% whole body impairment rating on top of the residual impairment rating.
• All extremity tingling/numbness can yield Positive NCV findings coupled with EMG finding.
• Muscle weakness, etc.
