   Sammanfattning : The overall aim of the thesis was to develop new methods for analysis of vocal fold vibrations and viscoelasticity and to test them in human subjects. In Study I the onset of vibration and irregular vocal fold vibration was examined with laryngoscopy using a high-speed camera at a frame rate of about 2000 images/sec. LÄS MER

   Sammanfattning : Tissue injury/scarring of the vocal folds (VFs) can be caused by various factors including external trauma, cancer treatment or inflammation, leading to damage within the vibrating layers and a decrease in viscoelastic functions. These effects ultimately result in severe voice problems. This condition leads to significant morbidity for patients. LÄS MER
