High Abnormal Rate in the Repetitive Nerve Stimulation Test in Acute Onset Myasthenia Gravis

Liik and Punga (2016) reported > 10% decremental response in the repetitive nerve stimulation (RNS) in 1 of 9 patients in the acute onset (AO) group (duration < 4 weeks) of generalized myasthenia gravis (MG). This finding is rather unexpected and contradictory to our common experience of a high rate of abnormal RNS findings in AO MG patients. Because this issue has not been adequately addressed in the literature, we are reporting our findings on this issue.
