Jitter measurement using a concentric needle in 133 patients with myasthenia gravis: A retrospective analysis

Abstract

Objectives: Single-fiber electromyography is being used in the diagnosis of patients with myasthenia gravis (MG) and is more sensitive, although less specific, than repetitive nerve stimulation (RNS). For the past two decades, concentric needle electrodes (CN) have been used in calculating jitter. In this retrospective study, we aimed to reveal the sensitivity of CN-jitter in patients with MG.
