Research has been conducted in order to determine whether or not it is possible to improve vital functions like coughing and swallowing. The study discussed in this post exploers expiratory muscle strength training (EMST) as a potential method of improving the cough and swallow functions.
- Cough is important for airway clearance in patients with dysphagia who are at risk of penetration/aspiration, such as people with Parkinson’s disease.
- Aspiration can occur during swallowing, and can lead to pneumonia and death.
- Expiratory muscle training (EMT) improved cough volume acceleration and decreases in the penetration/aspiration score.
RMT effectively improves cough and swallowing function in Parkinsons’ patients with dysphagia.
A variety of parameters from an airflow waveform produced during voluntary cough were measured in this study both pre-EMST and post-EMST. These include:
inspiratory phase duration.
The study found that there was a significant decrease in the duration of the CPD and EPRT after EMST. The decrease in EPRT resulted in a significant increase in cough VA. Significant decrease in the P/A scores were found to persist post training.
The results demonstrate that EMST is a viable treatment modality for a population of participants with PD who are at risk of aspiration.
