Expiratory Muscle Strength Training for Hypernasal Speech in Children

February 2, 2024 updated by: Noel Jabbour

Expiratory Muscle Strength Training as a Non-surgical Option for Velopharyngeal Dysfunction: A Randomized-controlled Trial

When the soft palate does not move enough because of a cleft palate or for unknown reasons, this can lead to a speech difference called velopharyngeal insufficiency. The purpose of this research study is to test if soft palate exercises using a hand help breathing device will help improve the ability of the soft palate to close the area between the throat and nose and help improve speech.

Study Overview

Detailed Description

The objective of this study is to examine the feasibility and efficacy of expiratory muscle strength training to improve velopharyngeal closure in patients with velopharyngeal dysfunction and nasal air emissions. A randomized, controlled trial will be conducted at a cleft craniofacial center at a tertiary children's hospital. Patients will be block randomized based on Pittsburgh Weighted Speech Scale (PWSS) score (3-6 or 7+) to Expiratory Muscle Strength Training for 6 to 8 weeks or no exercises. Patients with reductions in PWSS during this time will be further randomized to EMST maintenance training for 6 months or no exercises.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Expiratory Muscle Strength Training + No Maintenance Training
These participants were initially randomized to complete 6-8 weeks of exercises with EMST-150. They had improvement in their speech score of 2 points or more and were randomized to complete 6 months of no maintenance training.
At visit 1, participants will be block randomized based on PWSS score (3-6 or 7+) to Expiratory Muscle Strength Training (EMST) for 6 to 8 weeks or no exercises. Participants in the EMST-150 group will perform 5 sets of 5 resistive expirations once a day with a 10-15 second rest between each repetition and a 1-2 minute rest between each set of 5 repetitions.
Other Names:
  • EMST-150
No Intervention: No Exercises
These participants were initially randomized to 6-8 weeks of no exercises. They ended active study participation after the initial 6-8 weeks of no exercises. They were not eligible to be randomized to maintenance training or no maintenance training.
Experimental: Expiratory Muscle Strength Training + Maintenance Training
These participants were initially randomized to complete 6-8 weeks of exercises with EMST-150. They had improvement in their speech score of 2 points or more and were randomized to complete 6 months of maintenance training.
At visit 1, participants will be block randomized based on PWSS score (3-6 or 7+) to Expiratory Muscle Strength Training (EMST) for 6 to 8 weeks or no exercises. Participants in the EMST-150 group will perform 5 sets of 5 resistive expirations once a day with a 10-15 second rest between each repetition and a 1-2 minute rest between each set of 5 repetitions.
Other Names:
  • EMST-150
At visit 2, participants with improved (decreased) PWSS of 2 or more points, for whom the family and/or surgeon is not currently considering surgical intervention for VPI, will be further randomized to continue "maintenance" EMST exercises or no exercises for 6 months. Participants in the "maintenance" group will complete 3-5 sessions exercise sessions each week (rather than daily training), with 2 sets of 5 resistive expirations (rather than 5 sets)
Experimental: Expiratory Muscle Strength Training
These participants were initially randomized to complete 6-8 weeks of exercises with EMST-150. They did not have improvement in their speech score of 2 points or more and ended active study participation after the initial 6-8 weeks of exercises.
At visit 1, participants will be block randomized based on PWSS score (3-6 or 7+) to Expiratory Muscle Strength Training (EMST) for 6 to 8 weeks or no exercises. Participants in the EMST-150 group will perform 5 sets of 5 resistive expirations once a day with a 10-15 second rest between each repetition and a 1-2 minute rest between each set of 5 repetitions.
