The purpose of this pilot study was to determine the most efficient method to treat muscle tension dysphonia: semi-occluded vocal fold (SOVT) exercises as compared vocal hygiene education (VH) in an alternating treatment design. Previous research has documented a reduction in laryngeal tension with improved mean phonation time, airflow production, and improved Voice Handicap Index (VHI) scores using SOVT exercises. Additional studies have demonstrated improved vocal quality using VH. The results of this pilot study are based on a single female participant, recruited from Madigan Army Medical Center, with muscle tension dysphonia treated with SOVT exercises to the effects of VH alone using pre- and post-measures of perceived vocal effort through utilization of a visual self-rating analog scale. The data for this study are limited but could suggest the implementation of both direct and indirect treatment may improve vocal function. Keywords: Muscle tension dysphonia, semi-occluded vocal track exercises, vocal hygiene, visual analog scale.
