  1. Greetings, Thank you for your important question. Your model of seeking the research evidence behind treatments that you share with your group members should be commended. In this age of information, it can be overwhelming for us to navigate through all of the information we receive to determine which treatments, whether it be therapies, surgeries, medications, or non-traditional methods, have the most research to support their effectiveness. Given our limited time and resources, it is essential that our time be spent on treatments and activities that are effective in the most efficient way. In response to your specific question regarding a Comparison of Research between the speech treatments of LSVT LOUD and Speak Out: LSVT LOUD LSVT LOUD has over 20 years of published research data resulting from over 8 million dollars in funding from the National Institutes of Health (NIH). Thus, the research has been rigorously reviewed and controlled by the scientific and clinical communities. Research includes 3 large randomized control trials (considered the ‘gold standard’ of treatment effectiveness) as well as numerous other pre-post studies on over one hundred people with PD. These studies have been conducted by clinical researchers nationally and internationally, as well as our LSVT team. Results from these studies demonstrate positive treatment effects after one month of treatment which last for two years. Research results indicate a spreading of effects beyond increased loudness to improvements in articulation, respiration, vocal fold function, and intelligibility. Additionally, research indicates a positive impact of LSVT LOUD on facial expression, swallowing and brain function (PET imaging). Research demonstrates that LSVT LOUD has been successfully utilized with people with Parkinson Plus, post DBS surgery as well as other neurological disorders LSVT LOUD research documents changes in loudness during a variety of tasks following treatment, including, conversational speech, which is an indicator of a positive impact on functional daily communication in the life of people with PD! I have included a link here to a reference list that contains a list of the extensive studies: https://blog.lsvtglobal.com/research/ Because of the years of study and research support, LSVT LOUD is successfully reimbursed by Medicare and other insurance carriers. While personalizing the treatment to each person’s individual goals, LSVT LOUD therapists are trained to deliver LSVT LOUD according to how it has been researched, in order to maintain fidelity of treatment effects. There are now over 20,000 trained LSVT LOUD therapists in 72 countries. If your group members want to know more about LSVT LOUD, LSVT Global offers free monthly webinars, as well as on demand webinars on topics related to voice/speech and movement in PD. A list of these webinars can be found here: https://www.lsvtglobal.com/LSVTPublicWebinars Furthermore information can be obtained about finding LSVT LOUD trained therapists in members’ locations https://www.lsvtglobal.com/LSVTFindClinicians Speak Out Prospective pre-post publications listed on the Speak Out website include one small group study, and one case study: The studies were not randomized control trials Increases in loudness were only reported for single vowels, not the conversational level and did not include long term data Some improvements were noted on a voice related quality of life scale Thank you for your important question comparing the research base of LSVT LOUD and Speak Out. The ability to communicate is essential to quality of life for people with PD! Improving quality of life in individuals with PD through the power of communication is the mission of our team. We would be happy to help you and your group! Best wishes, Lorraine Ramig, Ph.D., CCC-SLP
