Abstract

Purpose The purpose of this study was to determine whether LSVT LOUD (Lee Silverman Voice Treatment) would improve vocal features, communicative effectiveness, quality of life, and cognition for a multilingual participant with complex comorbidities seeking treatment for hypokinetic dysarthria.

Method This study used a case study design. The participant completed 16 one-hour sessions of LSVT LOUD treatment. Pre, post, and three-month maintenance data were collected.

Results This study found improvements in measures of vocal quality, vocal loudness, intelligibility, communicative effectiveness, quality of life, and increases in cognitive functioning immediately post treatment. Three months post treatment, improvements in vocal quality, intelligibility, and some measures of quality of life were maintained.

Conclusion The results indicate that LSVT LOUD was an appropriate treatment choice for the participant and resulted in some meaningful changes in vocal quality, intelligibility, and quality of life
