Primary outcomePrimary: Change in Speech Intelligibility at 6 Months — 0.25; -4.78 score on a scale — p=0.13
Summary
Nearly 90% of people with Parkinson's disease have speech and voice disorders that negatively impact their ability to communicate effectively in daily life. This study will test the hypothesis that a combined speech and exercise intervention will improve speech intelligibility in people with Parkinson's disease and speech impairment. This approach would offer an affordable way to continue to both instruct and encourage training by Veterans virtually indefinitely through the remote access technology. These findings may help VA clinicians provide optimal care for the many Veterans with Parkinson's disease and speech impairment.
