Read our Parkinson Disease research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
The GEARS trial is testing whether high-intensity aerobic exercise—specifically cycling done three times a week in a community setting—can slow the progression of Parkinson's disease. Researchers also want to understand whether your genes affect how much the exercise helps you. This study will follow 200 people with Parkinson's disease over about 12 months to see if community-based exercise actually makes a real difference in slowing the disease.
While studies have shown that intensive exercise can help Parkinson's symptoms in controlled lab settings, we don't know if exercise works as well when people do it in their own communities, where most people actually live. This trial also aims to discover whether some people benefit more from exercise based on their genetic makeup, which could help doctors better tailor treatment plans.

You would visit Cleveland Clinic or University of Utah five times over about 12.5 months for assessments of how your Parkinson's symptoms are changing. Most importantly, you would exercise on a stationary bike three times per week in a community setting—not just in a lab—for the full 12 months. The researchers will ask you to stop taking your Parkinson's medication for some visits so they can see exercise's direct effect on your symptoms. They'll also take a genetic sample to understand your genetic risk for Parkinson's and track whether your genes affect how much the exercise helps you.
