The Effects of Adding Expiratory Muscle Strength Training in Voice Therapy

NCT03692494 · Status: WITHDRAWN · Phase: NA · Type: INTERVENTIONAL

Last updated 2025-02-07

No results posted yet for this study

Summary

Evaluate if adding expiratory muscle strength training to traditional voice therapy for individuals with dysphonia due to glottal insufficiency improves maximal expiratory pressure, acoustic and aerodynamic measures (i.e. amplitude, maximum phonation time, peak expiratory flow), and voice related quality of life.

Conditions

  • Dysphonia
  • Unilateral Vocal Cord Paralysis

Interventions

OTHER

Standard of care voice therapy

Exercises will include improved breath coordination, sustained humming and vowels, vocal glides, resonant voice therapy, and relaxation techniques to the neck and shoulder

OTHER

Expiratory muscle strength training (EMST)

EMST150 used at 75% of their maximum expiratory pressure. Participants will be directed to perform 5 sets of 5 breaths, 5 days per week, for 5 weeks, at the pressure threshold established in therapy. Maximum expiratory pressure will then be determined at the beginning of each therapy session and recalibration of the device will be performed if indicated.
