Functional outcomes associated with expiratory muscle strengthtraining: Narrative review

Helena Laciuga, MA; John C. Rosenbek, PhD; Paul W. Davenport, PhD; Christine M. Sapienza, PhD



• Aim– Review available evidence for effects of expiratory

muscle strength training (EMST) with use of pressure threshold device.

• Relevance– Reduced expiratory muscle strength may decrease

ability to generate adequate expiratory pressure for voice production or airway clearance during cough.



Method• Searched for articles published after 1994 in

PubMed, Cochrane, and Google Scholar databases.– Used phrases “expiratory muscle training” and “expiratory

muscle strength training.”

• Further reviewed articles uncovered after initial search to determine use of expiratory pressure threshold device.

• Selected 24 articles based on predetermined criteria.



Results

• EMST has been successfully applied to increase maximum expiratory pressure, with potential to improve some aspects of speech, swallow, respiration, and physical performance requiring adequate expiratory pressure.

• EMST could be future therapeutic approach to voice impairments or dysphagia.



Conclusion

• Further research should assess supportive function for EMST in combination with task-specific exercise programs targeting voice loudness, cough effectiveness, and swallow safety.
