Abstract
The purpose of this study was to determine the efficacy of the Lee SilvermanVoice Treatment (LSVT) on improving the vocal loudness in patients with Parkinson's
disease when delivered via distance therapy. This study utilized a non-concurrent
multiple baseline across subjects research design. Subjects were recruited through local
Parkinson's Support Groups. A total of five subjects participated in the study and each
subject received the standard LSVT techniques which included focus on using correct
breath control to project voice, projecting a range of high to low notes, and speaking
written sentences and words as loud as possible.
Three subjects received traditional face to face treatment and two subjects
received distance treatment via web camera through Skype. Treatment in both conditions
utilized the recommended one hour per day, four days per week treatment for four weeks,
along with homework and carryover tasks completed all 30 days. All five subjects
reported being satisfied with the treatment and indicated they would complete the
treatment again if necessary. The three subjects who received face to face therapy
demonstrated improvement in sound pressure level for at least two tasks from pretreatment
to post-treatment. One subject who received distance therapy demonstrated
improvement in sound pressure level for three tasks from pre-treatment to post-treatment.
The second subject who received distance therapy did not demonstrate an improvement
in sound pressure level from pre-treatment to post-treatment. Those subjects who were
motivated to complete the therapy and who received positive feedback from family and
friends demonstrated greater improvement in speech gains.
