Not recognising the presence of decreased excitability may give rise to a seemingly low compound muscle action potential, which may lead erroneously to the conclusion of conduction block. To quantify decreased electrical excitability, stimulation-response curves and the current needed to achieve 90% of the maximal compound muscle action potential amplitude, i90, were obtained in 17 healthy controls, eight patients with Guillain-Barre syndrome, 14 with chronic inflammatory demyelinating… CONTINUE READING
