Abstract
Background:
Previous research has established a close relationship between the glottis, located at the top of the thoracic cavity, and the pelvic floor, which forms the base of the abdominal cavity. Fascial connections and pressure-regulating mechanisms interconnect these structures both anatomically and functionally. Their interplay is crucial for activities requiring thoracoabdominal pressure modulation, including breathing, phonation, and continence. Recent practices among pelvic floor physical therapists have introduced phonation and vocalization cues to influence pelvic floor movements. However, a significant gap remains in understanding the precise coordination and movement patterns between the pelvic floor and glottis during speech and phonation.
Aims: This study reviewed the existing literature on the relationship between pelvic floor muscles (PFMs) and various phonation patterns to highlight the potential clinical benefits of understanding this interaction.
Methods: A literature search was conducted in PubMed, the Cochrane Library, and Google Scholar databases using the keywords "pelvic floor muscles," "glottis,” phonation,” "larynx," “epiglottis," “vocal folds,” and “thoracoabdominal pressure." The reviewed literature was descriptively analyzed and summarized.
Results: Most studies demonstrate a relationship between PFMs and phonation patterns, highlighting significant clinical implications.
Conclusion: The dynamics of PFMs and phonation patterns are intricately connected through shared physiological mechanisms and biomechanical interactions. Emerging therapeutic approaches leveraging phonation cues hold significant promise for improving pelvic floor function. Further research is needed to enable the development of targeted, effective rehabilitation strategies, ultimately enhancing patient outcomes in both vocal and pelvic health.
