Primary outcomePrimary: Treatment-related Changes in Vocal Intensity Will be Assessed Using Acoustic Analysis. — 3; 3; 0.26 Decibels
Summary
This study addresses several issues related to the clinical management of speech and voice disorders associated with Parkinson's disease. Two behavioral treatment programs, Lee Silverman Voice Treatment and SpeechVive, are assessed in their ability to improve communication in persons with Parkinson's disease.
