Effect of Pompage on Vocal and Respiratory Measurements from Female Teachers: A Randomized Clinical Trial

Abstract

Introduction: Teachers stand out among occupational groups due to their contribution to modern societies, and their voice is the main form of interaction. Objective: The aim of the study was to verify the changes in vocal and respiratory measurements from teachers with vocal and musculoskeletal complaints and with normal larynx after applying a musculoskeletal manipulation protocol of myofascial release using pompage. Methods: Controlled and randomized clinical trial with 56 participants: 28 teachers in the study group and 28 teachers in the control group. Anamnesis, videolaryngoscopy, hearing screening, sound pressure and maximum phonation time measurements, and manovacuometry were performed. The musculoskeletal manipulation protocol of myofascial release using pompage consisted of a total of 24 sessions, 40 min for each session, three times a week, for 8 weeks. Results: There was a significant improvement in the maximum respiratory pressure in the study group after the intervention. The sound pressure level and the maximum phonation time did not change significantly. Discussion and Conclusion: Musculoskeletal manipulation protocol of myofascial release using pompage had a direct effect on the respiratory measurements from female teachers, significantly increasing the maximum respiratory pressure but without affecting sound pressure level and the /a/ maximum phonation time.
