[Electromyography in the evaluation of the functional state of the internal neuromuscular apparatus of the larynx in myasthenia].

Using needle transcutaneous electromyography of internal laryngeal muscles and kalymin tests, 40 patients with myasthenia of different forms were examined. It was found that patients with generalized and local pharyngeal-facial forms of the disease developed latent generalization of myasthenic injury. Characteristic changes can be used to determine the degree of disorders in the internal nervous-muscular apparatus of the larynx.
