Using a smartphone app to increase exercise in people at risk for Parkinson's

This trial is testing whether a smartphone app can help you move more and stay more active in your daily life over two years. You'll be part of a study designed for people who have been diagnosed with REM sleep behavior disorder (a sleep condition where people act out their dreams), which puts you at higher risk of developing Parkinson's disease later. The study wants to see if increasing your physical activity early on—before any Parkinson's symptoms appear—might slow down or even prevent the disease from developing.

Parkinson's disease is growing faster than other brain diseases, and current treatments haven't been able to slow it down once it's fully developed. This trial is testing whether starting an exercise program much earlier—in people who show early warning signs but don't have Parkinson's yet—could be more effective at preventing the disease altogether.
