Speech therapy effective for struggling Parkinson's patients

A trial found that an intensive speech therapy called Lee Silverman Voice Treatment (LSVT LOUD), which involves loudly repeating words and phrases, is an effective treatment for Parkinson’s disease. Nearly 90% of Parkinson’s patients experience hypokinetic dysarthria, a speech disorder that makes their speech quiet, slurred, monotone, or jumbled. The therapy helps re-train patients' brains to produce a loud, clear voice for everyday speech. In the UK, researchers discovered that LSVT LOUD was more effective than other forms of speech therapy. In a trial with 388 patients, those who received four 50-minute LSVT LOUD sessions per week, either online or in person, showed better results in speech tests and reported improved quality of life. Voice quality was measured on a scale from 0 to 120, and patients receiving LSVT LOUD scored eight points higher than those who did not receive any speech therapy and nearly 10 points higher than those who received standard NHS speech therapy. Some participants experienced minor vocal strain, but researchers considered the side effects worth the significant improvements. They emphasized the need for healthcare systems like the NHS to adopt this therapy despite resource limitations. LSVT LOUD, developed in the US in the 1980s and named after its first patient, aims to help Parkinson’s patients “rev up” their voices through daily practice, becoming a lifelong habit even after the 16-session treatment ends. The therapy addresses the issue where Parkinson’s patients perceive their quiet voice as adequately loud due to the brain’s inability to recognize volume correctly.
