Abstract
Background: Video stroboscopy has been the only way to visualize vocal fold movement for more than 50 years. Now we can capture the true movement of the vocal folds with high-speed recordings. Objective: A prospective randomized study was made to show if high speed films gave supplementary information that was better than video stroboscopy for diseases of the laryngeal function. Method: Randomized treatments planned on high speed films compared with treatment plans based on video stroboscopy were made. Results: There were interesting differences between the treatments in the way that video stroboscopy indicated voice training and cortisone where on high speed films such indications was not found. Conclusion: As in other fields, evidence based focus is on the genetic – mucosal - vocal function. Correction of behavior models was found only to be supplementary.
