Official title
Biomechanical Effects of Expiratory Muscle Strength Training (EMST®) on Swallowing Function in Parkinson's Disease - a Prospective High-resolution Manometry Study
Overview
The aim of this non-randomized intervention study is to investigate the detailed effects of a structured four-week EMST® training program on the biomechanics of swallowing function in dysphagic Parkinson's patients. A combination of fiberoptic endoscopic evaluation of swallowing (FEES) and pharyngeal high-resolution manometry (HRM) will be employed to comprehensively evaluate the neuromuscular changes in swallowing.
Interventions
- Device exspiratory muscle strength training
5 sets of 5 breaths with EMST per day, 5 days a week for 1 month
Primary outcome measures
- Effect on swallowing biomechanics in pharyngeal high-resolution manometry as assessed by measurement of e.g. Pharyngeal contractile Integral (PhcI) [Time frame: 1 month and 3 months]
Secondary outcome measures (1)
- Pharyngeal swallowing safety and efficiency as assessed with fiberoptic endoscopic evaluation of swallowing (FEES) applying DIGEST-FEES scoring [Time frame: 1 month and 3 months]
Eligibility 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
Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
