The repetitive ocular vestibular evoked myogenic potentials (RoVEMP) test can measure the neuromuscular transmission of extraocular muscles leading to a better and more accurate diagnosis of myasthenia gravis (MG).
Why this matters ?
Fatigable muscle weakness, particularly in ocular muscles, affects a large subset of patients with MG, an autoimmune disease. Accurately diagnosing patients with MG is challenging as current neurophysiological tests cannot measure extraocular muscles. The results of this study provide evidence for a new neurophysiological test to accurately diagnose individuals with MG.
