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.

MEP and swallowing safety measured: – Pre-EMST (baseline). – Post-EMST (predetraining). – 3 mo postdetraining.

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.
