Detraining outcomes with expiratory muscle strength training in Parkinson disease. J Rehabil Res Dev. 2014;51(2):305– Slideshow Project DOI: /JRRD JSP Aim – Examine changes in maximum expiratory pressure (MEP) and swallowing safety after 3 mo of expiratory muscle strength training (EMST) detraining in persons with Parkinson disease (PD). Relevance – EMST improves MEP, cough function, and swallowing safety in PD. However, no published reports describe detraining effects after EMST in persons with PD or after any behavioral swallowing intervention.

J Rehabil Res Dev. 2014;51(2):305– Slideshow Project DOI: /JRRD JSP Method 10 participants with PD underwent 3 mo of detraining following EMST. MEP and swallowing safety measured: – Pre-EMST (baseline). – Post-EMST (predetraining). – 3 mo postdetraining.

Detraining outcomes with expiratory muscle strength training in Parkinson disease. J Rehabil Res Dev. 2014;51(2):305– Slideshow Project DOI: /JRRD JSP Results Participants demonstrated 19% improvement in MEP from pre- to post-EMST. Following 3 mo detraining period: – MEP declined by 2% yet remained 17% above baseline. – 7 participants demonstrated no change in swallowing safety, 1 worsened, and 2 improved. Swallowing safety did not significantly change from post-EMST to postdetraining.
