Abstract
The purpose of this study was to determine the efficacy of the Lee Silverman Voice 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.
