# Improve swallowing through breath training

**Goal (in five words):** Improve swallowing through breath training

**Official Title:** Biomechanical Effects of Expiratory Muscle Strength Training (EMST®) on Swallowing Function in Parkinson's Disease - a Prospective High-resolution Manometry Study

**Trial ID:** [NCT07606547](https://clinicaltrials.gov/study/NCT07606547)

## Key Facts

- **Phase:** NA
- **Status:** RECRUITING
- **Study Type:** INTERVENTIONAL
- **Sponsor:** University Hospital Muenster
- **Target Enrollment:** 30 participants
- **Start Date:** 2026-06
- **Completion Date:** 2028-05
- **Conditions:** Parkinson's Disease (PD), Dysphagia
- **Interventions:** exspiratory muscle strength training
- **Intervention Types:** DEVICE

## Summary For Families

The goal is to see whether strengthening the muscles you use to blow out forcefully can improve swallowing safety and reduce aspiration in people with Parkinson's who have dysphagia. The approach uses expiratory muscle strength training, a resistance breathing exercise that makes expiratory and airway-protecting muscles work harder so cough strength and the pressure patterns during swallowing improve, and the team will use high-resolution manometry to measure those pressure changes precisely. Adults 18 and older with Parkinson's whose dysphagia has been confirmed by FEES are eligible, people with severe dementia or dysphagia from other causes are excluded, and about 30 participants are planned starting June 2026.

## Eligibility

- **Minimum age:** 18 Years
- **Sex:** ALL

### Full Criteria

```
Inclusion Criteria:

* diagnosis of Parkinson's disease,
* PD-related dysphagia as objectively diagnosed with FEES

Exclusion Criteria:

* severe dementia, not able to give consent
* dysphagia related to other diagnoses
```
