Abstract
The Lee Silverman Voice Treatment (LSVT) has been shown to be highly effective in treating the speech disorder in Parkinson's Disease (PD). However, patient access to this treatment remains limited in Australia, due to availability of speech pathologists, patient mobility and distance issues. We have investigated the feasibility and effectiveness of an Internet-based telerehabilitation application (eREHAB) for the delivery of the LSVT to persons with PD and disordered speech. Ten participants with PD and dysarthria were treated online with the LSVT for a total of 16 sessions. There were significant improvements in sound pressure levels for vowel prolongation, reading and conversational monologue (P<0.01), pitch range (P<0.05) and in perceptual features of pitch and loudness variability, loudness level (P<0.01) and breathiness (P<0.05). A participant satisfaction questionnaire indicated that 70% of participants expressed overall satisfaction with the online treatment. Telerehabilitation was feasible and effective in delivering the LSVT to people with PD.
