Clinical Trial Summary

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.

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.

Intervention

Device:
• Expiratory Muscle Strength 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.
• Maintenance Training
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)
