Parkinson’s Disease

What is it?
​Parkinson’s disease is a progressive neurological disorder characterized by bradykinesia (slow movements), rigidity of movement, and a resting tremor.  Parkinson’s disease can also affect voice production as patients develop difficulty producing a loud voice due to incomplete closure of the vocal folds.

How is it treated?
Parkinson’s disease should be followed by a neurologists.  Lee Silverman Voice Treatment (LSVT) is an intensive 1-month voice therapy regimen that is shown to improve the loudness of patients’ voices with Parkinson’s disease.  Despite the successes of LSVT, some patient continue to worsen or fail to improve with therapy alone.  Such patients may be candidates for an office-based injection to improve voice, which, if successful, may suggest more permanent improvement with the use of a permanent implant.
