Stimulated single-fiber electromyography (sSFEMG) in Lambert-Eaton syndrome Vincenzo Todisco, Giovanni Cirillo, Rocco Capuano, Alessandro d'Ambrosio, Gioacchino Tedeschi, Antonio Gallo Clinical Neurophysiology Practice Volume 3, Pages 148-150 (January 2018) DOI: 10.1016/j.cnp.2018.07.001 Copyright © 2018 International Federation of Clinical Neurophysiology Terms and Conditions

Fig. 1 Neurophysiological tests in LEMS. Representative neurophysiological diagnostic approach in patients with LEMS. (A) the baseline low amplitude of the median nerve compound muscle action potential (CMAP) from right abductor pollicis brevis (APB) was significantly increased after brief isometric exercise; (B) in the same muscle, low- (LF) and C) high-frequency (HF) repetitive stimulation test (RST) showed significant decremental (B) and incremental response (C), respectively.

Fig. 2 Frequency-dependent neuromuscular jitter in LEMS. Stimulated single-fiber electromyography (sSFEMG) demonstrated a frequency-dependent reduction of the neuromuscular jitter values at the increase of the stimulation rate.
