Qualitative assessment of kymograms and open quotient (OQ) values were obtained from VSK examination of over 300 patients presenting with vocal fold (VF) immobility or dysmobility. Qualitative assessment showed reduced amplitude of VF vibrations in patients with VF immobility. The OQ values for the anterior, middle, and posterior areas of the VF were higher compared to the control group.
