Technology-supported delivery of effective speech treatment for Parkinson disease
What is it about?
The majority of individuals with Parkinson disease (PD) have speech and voice disorders. LSVT®LOUD (Lee Silverman Voice Treatment) is an evidence-based treatment that currently is being delivered in 60 countries to help individuals with PD improve their ability to communicate. However, access to this treatment may be challenging for individuals who have mobility constraints or who do not have contact with clinicians who are trained in this method. This study evaluated an interactive, customized software-based program, the LSVTCompanion® to deliver LSVT LOUD as an independent “at-home” clinician for a portion of the treatment sessions. Results supported the use of this system in treating speech and voice disorders in PD. See Resources Video LSVTCompanion Client Edition Demonstration.
Why is it important?
This study provided the first evidence that individuals with PD who used the LSVTCompanion had treatment gains comparable to individuals who received the standard in-person LSVT LOUD. Furthermore, these individuals were able to use the LSVTCompanion independently at home and reported that it was very helpful. Outcomes on sound pressure level (reflecting vocal loudness) and listener and significant other ratings supported a positive post-treatment impact on speech and voice.
