The paucity of easy-to-use, reliable objective neuromuscular monitors is an obstacle to universal adoption of routine neuromuscular monitoring. Electromyography (EMG) has been proposed as the optimal neuromuscular monitoring technology since it addresses several acceleromyography limitations. In this issue of Anesthesiology, Nemes et al. compared simultaneous neuromuscular responses recorded from induction of neuromuscular block until recovery using the acceleromyography-based and EMG-based monitors. In an accompanying editorial, Bowdle and Michaelsen discuss the limitations of both monitoring techniques and the need for further validation of currently commercially available EMG-based monitors.
