Expiratory muscle strength training (EMST) is efficacious for improving maximum
expiratory pressure (MEP), cough function, and swallowing safety in Parkinson
disease (PD). However, there are no published reports describing detraining
effects following EMST in persons with PD. Moreover, there are no published
reports describing detraining effects following any behavioral swallowing
intervention. Ten participants with PD underwent 3 mo of detraining following
EMST. Measures of MEP and swallowing safety were made prior to beginning EMST
(baseline), posttreatment (predetraining), and 3 mo postdetraining. Participants
demonstrated, on average, a 19% improvement in MEP from pre- to post-EMST.
Following the 3 mo detraining period, MEP declined by 2% yet remained 17% above
the baseline value. No statistically significant changes were found in swallowing
safety from post-EMST to postdetraining period. Following the 3 mo detraining
period, seven participants demonstrated no change in swallowing safety, one
worsened, and two had improvements. This preliminary study highlights the need
for the design of maintenance programs to sustain function following intensive
periods of training.
