EMG and Nerve Conduction Studies in Clinical Practice

WitrynaNow, we have two kind of “EMG” tests used for Myasthenia Gravis (MG). The repetitive nerve stimulation (RNS) and Single fiber electromyography (SFEMG). If you had the RNS, then it is positive in about 55-77%, but I must say it correlates very well with the severity of MG. The other test the SFEMG is more sensitive 77-100%.
