Repetitive nerve stimulation is a simple and widely used technique to demonstrate neuromuscular transmission defect. A significant decremental response for repetitive hypoglossal nerve stimulation was obtained from the surface recordings in the tongue of a patient with dysarthria and dysphagia. Repetitive hypoglossal nerve stimulation test may be useful in diagnosis of myasthenia gravis with bulbar symptoms only. We utilized repetitive hypoglossal nerve stimulation with tongue recordings and diagnosed a case of myasthenia gravis.
Key words: Myasthenia gravis, Repetitive nerve stimulation, Hypoglossal nerve.
