Antecedent poliomyelitis was demonstrated in all patients by electromyography or muscle biopsy or both.
Evidence of remote denervation consistent with antecedent poliomyelitis was demonstrated in all patients by electromyography or muscle biopsy or both.
Nerve conduction testing may be combined with electromyography (EMG), an electrical test of the muscles.
Electromyography (EMG)-A diagnostic test that records the electrical activity of muscles.
Laboratory tests include electromyography (a measurement of the electrical activity of muscle cells) and nerve conduction velocity tests, which measure the speed that nerves transmit impulses.
