title: [Electromyography of the external muscles of the larynx in the combined diagnosis of hypokinetic dysphonia].
abstract: Bioelectric activity of elevators and depressor of the thyroid cartilage were studied in 135 patients with hypokinetic dysphonia versus 30 healthy subjects. At the primary diagnosis and in controls this activity for the inferior muscles exceeded that for the superior ones 1.2-1.4-fold. One year after the diagnosis the superior muscles were 1.2-1.6-fold more active, whereas in later terms both activities correlated or the increase was less than 1.2-fold. Basing on the studies, early clinical signs of functional dysphonias are suggested promoting more precise diagnosis and decision on the voice problem treatment.
