Blood flow restriction to improve balance in Parkinson's
This study tests whether gently restricting blood flow to your legs during exercise can help improve balance for people with Parkinson's disease. You will do simple leg exercises while wearing a special cuff, which may strengthen muscles and improve steadiness.
San Antonio, TexasAges 40–85 - NCT05516732Recruiting
Testing serotonin activity in the brain in people with Parkinson’s
This study uses special scans to measure how serotonin is released in parts of the brain involved in movement in Parkinson’s disease. It may help researchers understand disease changes and the role of serotonin systems in movement problems.
Exeter, DevonAges 25–85 - NCT05516719Recruiting
Study tracking I2BS in Parkinson’s over time
This study follows people with Parkinson’s to see how “I2BS” changes over time using special brain scans and other tests. It may help researchers better understand Parkinson’s and improve how it’s measured in future trials.
Exeter, DevonAges 25 years+ - NCT05962489Recruiting
Sleep-focused DBS therapy study for Parkinson’s disease
This study looks at a sleep-focused approach to brain stimulation (DBS) in people with Parkinson’s disease. You may be able to join if you’re planning or scheduled for specific DBS surgery at the University of Minnesota and have the needed brain imaging.
Minneapolis, MinnesotaAges 21 years+ - NCT04735458Recruiting
Brain network study for Parkinson’s or essential tremor
This study looks at how “inhibitory control” brain networks work in people with Parkinson’s disease or essential tremor. If you are eligible for surgery and can do the study tasks, your results may help researchers better understand movement disorders and guide future treatments.
Birmingham, AlabamaAges 18 years+ - NCT05748028Recruiting
Testing treatment for pain and nerve symptoms in Parkinson’s
This study looks at pain and “autonomic” (automatic body) symptoms in people with Parkinson’s disease or a related condition called multiple system atrophy. It aims to understand what helps and to learn more about these symptoms in different types of Parkinson-like illnesses.
Telese Terme, BeneventoAges 18 years+ - NCT05568498RecruitingPhase 2
Probiotic trial for depression in Parkinson’s disease
This Phase 2 study tests whether taking probiotics can improve depression and mood symptoms in people with Parkinson’s disease. It’s meant for those with mild to moderate depression and stable Parkinson’s and mood treatments.
Vancouver, British ColumbiaAges 40–80 - NCT05065060Recruiting
Parkinson study tracking health online and long-term
This study aims to better understand Parkinson’s disease over time by collecting health information online. You may join if you have Parkinson’s, or if you don’t, to compare changes and help researchers find useful markers.
San Francisco, CaliforniaAges 18 years+ - NCT04566341Enrolling by invitation
Study gut problems in Parkinson’s and changes in gut nerves
This study looks at how digestive (gut) problems happen in people with Parkinson’s and whether there are related changes in the nerve tissue in the digestive tract. It may help researchers better understand the cause of these symptoms and find new ways to monitor or treat them.
Boston, MassachusettsAges 40–85 - NCT04616508Recruiting
Online arm movement training for people with Parkinson’s
This study uses online tasks to look at how people with Parkinson’s control reaching movements. You may benefit by contributing to research that could improve understanding and future treatments for movement problems.
Newark, DelawareAges 18–85 - NCT05025254Recruiting
Online thinking tests for people with Parkinson’s disease
This study tests online “thinking” (cognitive) abilities in people with Parkinson’s disease. It may help researchers better understand how thinking changes over time and how tests can be done from home.
Montreal, QuebecAges 45–90 - NCT05769699Recruiting
Blood test study for Parkinson’s stages
This study measures blood biomarkers (measurable substances in blood) in people with Parkinson’s at different stages. It may help doctors understand how Parkinson’s changes over time and could guide future testing or treatments.
RomaAges 18–80 - NCT05741151Recruiting
Testing a nerve target in Parkinson’s disease
This trial is studying the “superior cervical ganglion” as a possible treatment approach for Parkinson’s disease. It may help people whose symptoms are truly caused by Parkinson’s, not by another condition.
RomeAges 30–80 - NCT05752656Recruiting
Tracking outcomes after deep brain stimulation for Parkinson’s
This study follows people with Parkinson’s disease to see how their thinking, behavior, and movement change over time after deep brain stimulation. It may help doctors better understand what to expect from this treatment.
RomeAges 18 years+ - NCT05908266Recruiting
Training control for reaching in Parkinson disease
This study tests a way to help people control reaching movements during a task. You may be able to join if you can understand the instructions and successfully perform the reaching task during the experiment.
Louvain-la-NeuveAges 18–99 - NCT05908279Recruiting
Walking and gait study in people with Parkinson’s disease
This trial studies walking patterns and how walking is controlled in people with Parkinson’s disease. It may help researchers understand movement control and improve future therapies by comparing walking ability and patterns.
Louvain-la-NeuveAges 18–99 - NCT05981261Recruiting
Experimental pain study in Parkinson's and healthy adults
This study looks at how people with Parkinson’s, treated either with levodopa or deep brain stimulation (DBS), and healthy volunteers experience pain. The goal is to understand how Parkinson’s treatments affect pain perception.
AarhusAges Any age - NCT06090682Recruiting
Brain stimulation for Parkinson's with thinking problems
This trial tests a brain stimulation technique (deep brain stimulation) to see if it can help people with Parkinson's disease who also have mild cognitive problems. The goal is to understand how stimulation affects both movement and thinking.

Common questions
- Are there clinical trials for parkinsonism?
- Yes. Clin2 currently lists 732 recruiting parkinsonism studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a parkinsonism trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a parkinsonism trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
