Özet:

 Objective: This research offers a comprehensive analysis of Myasthenia Gravis MG, uncovering the remarkable accuracy of spinal accessory, ulnar, and facial nerve repetitive nerve stimulation RNS, along with the precision of single fiber electromyography SF-EMG in MG diagnosis. We also embark on an exploration of clinical features and autoantibody test results in generalized MG patients. Methods: In this prospective study, we welcomed 31 individuals definitively diagnosed with generalized MG into our quest. The categorization of patients was conducted in accordance with the criteria set by the Myasthenia Gravis Foundation of America MGFA. We examined patients trapezius, nasalis, and abductor digiti minimi ADM muscles using RNS. We meticulously recorded the presence of MG autoantibodies, clinical subtypes based on affected muscle groups, and SF-EMG jitter rates. Results: The mean age of the 31 patients of whom 19 61.3 were male, was 64  13.9 years. Among them, 20 showed positivity in the Anti-AChR antibody test. In 28 patients, accounting for 90.3 of the study group, single fiber electromyography EMG displayed increased jitter. There were 4 12.9, 24 77.4 and 12 38.7 patients featuring a decremental response of exceeding 10 in ADM, trapezius and nasalis muscles, respectivelyOur investigation revealed notable findings, such as the absence of substantial correlations between decremental response rates and age, gender, duration of complaints, antibody test results, thymus abnormalities, affected muscle types, familial history, or increased jitter rates in SF-EMG p0.05. Conclusion: As our findings clearly show, we can confidently attest to the remarkable sensitivity of RNS in MG diagnosis when muscle selection is precise. A gem discovered on our study is the high sensitivity of the spinal accessory nerve, a revelation that should guide the course of routine RNS studies, particularly for those facing ocular-onset myasthenia.
