The EMG bar in the CSM cannot substitute a Train of Four (TOF) measurement. The reason for this is that the facial muscles are much more resistant to muscle relaxants than for example hypothenar (wrist) muscles. On the other hand, if the EMG in the CSM is 0 then the patient is most likely to be without muscular response.
