Voice studies in Parkinson and other neurologic diseases

Past and Present Research: Through research funded by the National Institutes of Health (NIH-NIDCD), the Office of Education (OE-NIDRR), and numerous private foundations (Davis Phinney Foundation, Parkinson's Alliance) , past and present members of the Parkinson's Team have studied the effects of behavioral, surgical and pharmaceutical interventions on speech and voice disorders in Parkinson's disease and other neurological disorders. Much of this research has centered around the effectiveness of intensive voice therapy (LSVT®) for improving speech and voice in PD. However, current efforts also extend to the study of non-speech behaviors, including swallow function and nonverbal communication.

Current projects include:

• The study of alternate speech therapies for Parkinson's disease
• Voice treatment for individuals with Parkinson's disease following Deep Brain Stimulation surgery (STN-DBS)
• The effects of early speech intervention on neuroplasticity
• Examination of acoustical markers of PD for earlier detection of the disease
• Applying principles of intensive voice therapy to physical therapy in Parkinson's disease.
