Many people with Parkinson's report problems with their voice or speech but there is little evidence as to what is a clinical and cost effective therapy to help people.
In this study participants were randomised to the Lee Silverman Voice Treatment (LSVT), standard NHS speech and language therapy, or no therapy for at least 12 months. LSVT is an intensive programme of voice exercises for people with Parkinson's.
The study is assessing if any of the therapies are maximising the speech intelligibility and communication of those taking part, and improving their quality of life.
Participants were assessed when they joined the trial and then by post at 3, 6 and 12 months.
