Videophone-Delivered Voice Therapy: A Comparative Analysis of Outcomes to Traditional Delivery for Adults with Parkinson's Disease

Individuals with idiopathic Parkinson's disease (IPD) usually develop a speech disorder characterized by reduced loudness, hoarse and breathy voice, monotony of pitch, short rushes of speech, and imprecise consonants. The inability to effectively communicate impairs their ability to function in society and quality of life. A successful program developed to improve speech in these individuals is the Lee Silverman Voice Treatment (LSVT)(R). A critical component of this treatment is intense daily therapy for 4 weeks, a regimen that is difficult for many elderly patients to complete. Treatment delivered through videophones placed in the homes of individuals with IPD offers an alternative and could improve accessibility of treatment if the results were the same. This study compared the outcomes of LSVT (R) delivered via videophones to the outcomes of traditional treatment delivered face-to-face.
