Electromyographic approach to neuromuscular junction disorders repetitive nerve stimulation and single-fiber electromyography.

Understanding the physiology of the NMJ aids the electromyographer in understanding how NMJ testing was developed. Practicing the RNS protocol on healthy subjects helps the electromyographer gain greater comfort with the implementation of a test that is not performed daily. The practice parameter proposed by the AAEM has established guidelines for testing and for diagnosing NMJ disorders using RNS and single-fiber EMG.
