(2) no evidence of infection with poliovirus
(3) neurological and functional disability
(4) exclusion of other explanations
(1) muscle weakness
(2) abnormal muscle fatigability
(3) segmental muscle atrophy
Nerve conduction studies may show:
(1) reduction in compound muscle action potential amplitudes
(2) normal sensory nerve action potential amplitudes
