EMST and LSVT in Patients with Parkinson Disease
Christine Carmichael, Christine Sapienza, Bari Ruddy, Lorraine Ramig

Parkinson disease (PD) affects multiple physiological processes associated with speech, voice and swallowing. The Lee Silverman Voice Treatment (LSVT) has proved to be an effective technique for improving vocal function with some evidence that swallow is enhanced post-treatment. Expiratory muscle strength training (EMST) shows promise for improving respiratory, cough and swallow functions with less impact on the loudness of speech than LSVT. This 13-week experimental protocol investigated the effects of EMST and LSVT in a small sample of patients with idiopathic PD. Preliminary results indicate that EMST with LSVT increases functions for breathing, cough magnitude, speech, and swallowing. Differences in LSVT and EMST techniques were determined by comparing the outcome measures following each training program. Outcomes after the combination of the two techniques were also examined.
