Can cycling unlock brain secrets in Parkinson's?
NCT ID NCT07442747
First seen Jun 27, 2026 · Last updated Jul 29, 2026 · Updated 2 times
Summary
This study looks at people with advanced Parkinson's disease who already have a brain device (deep brain stimulation). Researchers want to understand how aerobic exercise—specifically cycling—changes movement, thinking, and brain activity. Thirty-six participants will do an eight-week cycling program, and the team will measure symptoms and brain signals to uncover the mechanisms behind exercise benefits.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- aerobic exercise (cycling)
- What this could lead to
- If it works, this could reveal how exercise improves Parkinson's symptoms, pointing toward better exercise-based therapies.
- What could go wrong
- This is a small, early-stage study (36 people) focused on understanding mechanisms, not testing a treatment. Results may not apply to all Parkinson's patients.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Clinical diagnosis of Parkinson's disease * Previous placement of bilateral Medtronic Percept DBS as standard of care treatment for PD * Clinically optimized DBS parameters for one month prior to enrollment * Ability to ambulate with or without an assistive device for 5 continuous minutes * Willingness to withhold antiparkinsonian medication and DBS stimulation for outcomes assessments Exclusion Criteria: * Neurocognitive impairment that compromises the ability to provide informed consent * Neurological disease other than Parkinson's disease (i.e. multiple sclerosis, stroke) * Recommendation for medical clearance using the American College of Sports Medicine (ACSM) Preparticipation Health Screen: 1. If the ACSM screen recommends medical clearance, the subject must obtain medical clearance by their health care provided prior to participation. 2. Those who choose not to obtain physician clearance will not be eligible for participation. Those who do not receive physician clearance for high intensity exercise will not be eligible. * A musculoskeletal issue (arthritis, osteoporosis, back problem) that would limit one's ability to engage in exercise * Current cardiac arrhythmia
