Guidelines for single fiber EMG
These guidelines express the consensus of international experts on the current status of Single Fiber EMG (SFEMG) and the measurement of neuromuscular jitter with concentric needle electrodes (CNE–CN jitter).1 The authors describe methods for evaluating fiber density (FD) and define the criteria for acceptable signals (spikes with amplitude >200 µV and rise time <300 µs, constant shape at consecutive discharges and absence of notches or inflections).
