Clinical features and electrodiagnostic tests can help differentiate poliomyelitislike syndrome from Guillain-Barre syndrome by localizing damage primarily to motor axons, anterior horn cells, or both, with relative sparing of sensory nerves in the former, as opposed to localizing the damage to peripheral myelin or muscle in the latter (18,31,32,34).
