Aims
Determine the effects of EMST on expiratory pressure, cough, and swallowing in HNC survivors.
Background
Chronic radiation-associated dysphagia can be refractory to traditional therapy; EMST involves forceful expirations.
Methods
8-week EMST protocol with home practice and weekly in-clinic adjustments; outcomes included MEP, PEFR, FOIS, PSSHN, MDADI.
Results
MEP increased by 50%, but PEFR and QOL scores showed no significant improvement. FOIS median improvement was 1 point.
Conclusion
EMST for HNC-related dysphagia has mixed outcomes, requiring careful consideration of its commitment.
Lessons Learnt
Recruitment and data collection were challenging due to COVID-19 disruptions.
Additional Information
