To address these issues, expiratory muscle training (EMT) alone or in combination with postural techniques was tested to improve dysphagia in PD patients.
- The pharyngeal phase of swallowing is often affected in people with Parkinson’s disease (PD), contributing to dysphagia.
- Respiratory muscle strength is essential for swallowing.
- Respiratory muscle training (RMT) alone or in combination with postural techniques improves dysphagia in PD patients, confirmed by videofluoroscopic studies.
- The combination of the two methods is most effective.
- RMT effectively improves dysphagia in people with Parkinson’s disease.
Dysphagia was assessed by videofluoroscopic imaging (VFS) in PD patients before and after 4 weeks of EMT or EMT plus postural techniques, including chin tucking, head rotation, head tilting, bending head back, and lying down straight.
EMT alone and EMT plus postural techniques reduced the VFS score, with the combination of both techniques being more effective.
In conclusion, EMT, alone or in combination with postural techniques, was shown to improve dysphagia in PD patients.
