Fracture Toughness of Vocal Fold Tissue: A Preliminary Study
Journal of Voice (2016) Vol. 30, No. 3, pp. 251-254

A customized mechanical tester that slices thin, soft samples was used to measure the fracture toughness of vocal fold tissue. Porcine vocal fold lamina propria was subjected to quasi-static, guillotine-like tests at three equally distanced regions along the anterior-posterior direction. ...

Electroglottography in Fasting Subjects
Journal of Voice (2015) Vol. 29, No. 2, pp. 165-169

Objective: To make a comparative analysis on the closed quotient (CQ) of the sustained vowel /e/ while fasting and nonfasting. A total of 20 male subjects were enrolled. The mean age was 30.45 ± 8.79 years with a range of ...

Homeostasis of Hyaluronic Acid in Normal and Scarred Vocal Folds
Journal of Voice (2015) Vol. 29, No. 2, pp. 133-139

Vocal fold scarring is one of the most challenging laryngeal disorders to treat. Hyaluronic acid (HA) is the main component of lamina propria, and it plays an important role in proper vocal fold vibration and is also thought to be ...

Effect of Transcranial Direct Current Stimulation on Neurorehabilitation of Task-Specific Dystonia: A Double-Blind, Randomized Clinical Trial
Medical Problems of Performing Artists (2015) Vol. 30, No. 3, pp. np

Task-specific focal hand dystonia can disable affected individuals. Although neurorehabilitation techniques such as sensory motor retuning can result in complete recovery in some patients, it requires many months of treatment. Combining transcranial direct current stimulation (tDCS) with neurorehabilitation is a ...

Time-Dependent Pressure and Flow Behavior of a Self-oscillating Laryngeal Model With Ventricular Folds
Journal of Voice (2015) Vol. 29, No. 6, pp. 649-659

The purpose of the study was to better understand the pressure-flow behavior of a self-oscillating vocal fold model at various stages of the glottal cycle. An established self-oscillating vocal fold model was extended to include the false vocal folds (FVFs) ...

Vibrato Changes Following Imagery
Journal of Voice (2015) Vol. 29, No. 2, pp. 182-190

This study investigated acoustic change in singers' vibrato following imagery and non-imagery tasks. The study used a fully randomized cross-over (six conditions * two times) block design, in which each singer received each intervention in random order. Data were analyzed ...
