| Abstract | Background: Understanding the biomechanics of vocal folds has significant clinical implications concerning the selection of therapeutic exercises in voice rehabilitation, and their impact on vocal fold vibratory patterns. It is essential to know the state-of-the-art of biomechanics before and after voice exercises to improve the effectiveness of therapies.
Objective: This systematic review focused on how modifications of voice performance through vocal exercises affect the vibratory patterns of the vocal fold.
Methods: To identify the most relevant literature, a search in PubMed, using the MESH terms “((vocal folds) AND (biomechanics)) OR (voice training)) OR (voice disorders)” was performed. Additionally, some articles not found by the initial search were included manually due to their scientific relevance to the biomechanics of vocal folds after specific therapies. Of the 227 articles reviewed, 220 were excluded during different stages of filtering because they did not address the question of the present review, and only seven met the inclusion criteria.
Results and Conclusions: These studies show the relationship between the biomechanics of vocal fold vibration and therapeutic vocal exercises. For instance, modifications of voice behavior through vocal exercises can indeed affect the vibratory patterns of the vocal fold. Vocal function exercises are more effective in muscle tension dysphonia, and resonant voice therapy is more effective in dysphonia related to nodules or polyps. Therefore, different types of pathologies require tailored therapeutic approaches. The study of vocal fold biomechanics is crucial in determining the effectiveness of therapeutic vocal exercises for improvement in voice performance.
