Summary

This trial tests if breathing exercises with a small device can help people with speech problems caused by a cleft palate or similar issues. The exercises aim to make the muscles stronger so that the soft palate can close better, improving speech.

Who is the study for?
This trial is for children aged 5-17 with a speech difference called velopharyngeal insufficiency, often due to cleft palate. They should have noticeable speech issues (score of 3 or higher on a specific scale) and must be able to do the exercises in the study. Kids who've had previous speech surgery or have one scheduled within two months can't join.
What is being tested?
The study tests if using a handheld breathing device for soft palate exercises can improve the closing function between throat and nose, potentially enhancing speech quality in kids with velopharyngeal insufficiency.
What are the potential side effects?
Potential side effects are not specified but may include discomfort from using the breathing device, fatigue from performing exercises, or soreness in muscles involved in training.

Trial Design

4Treatment groups
Experimental Treatment
Active Control
Group I: Expiratory Muscle Strength Training + No Maintenance TrainingExperimental Treatment1 Intervention
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.
Group II: Expiratory Muscle Strength Training + Maintenance TrainingExperimental Treatment2 Interventions
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.
Group III: Expiratory Muscle Strength TrainingExperimental Treatment1 Intervention
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.
Group IV: No ExercisesActive Control1 Intervention
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.

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
Velopharyngeal insufficiency (VPI) treatments often focus on strengthening the soft palate muscles to improve their ability to close the gap between the throat and nose during speech. Exercises using hand-held breathing devices are designed to enhance the strength and coordination of these muscles, which is essential for reducing hypernasal speech and improving speech clarity. This non-invasive approach directly targets the muscle weakness that causes VPI, offering a practical solution for patients to achieve better speech outcomes.
