Patient-specific 3D action observation in immersive virtual reality for Parkinson's
Official title: Examining the Effect of Action Observation Training Using Patient-Specific 3D Records in Parkinson's Patients
Run by Abant Izzet Baysal University · NCT07250672 · Data updated 2026-11-12
This project will test whether watching your own 3D-recorded movements in an immersive virtual-reality headset can speed up movements and reduce bradykinesia in people with Parkinson's disease.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are people with a neurologist-confirmed Parkinson's diagnosis who can walk independently, are on stable antiparkinsonian medication, and have Hoehn and Yahr stage 3 or lower.
✕Probably not a fit
Patients with additional neurological disorders, recent changes in Parkinson medication, significant 3D vision impairments, high simulator sickness scores, or inability to walk independently may not benefit or be eligible.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
Participants will wear fully immersive virtual-reality headsets and observe rhythmic movements captured from their own 3D motion recordings, with a comparison group viewing healthy-model recordings. The intervention delivers repeated action-observation sessions aimed at improving bradykinesia and rhythmic motor control, with assessments over time to gauge lasting effects. Primary outcomes focus on changes in bradykinesia and spontaneous finger movement speed, while secondary outcomes include other motor and functional disease-related measures. The protocol excludes people with significant 3D-vision problems, high simulator sickness scores, other neurological disorders, or recent medication changes to ensure safety and reliable VR exposure.
Why it matters
Potential benefit: If successful, personalized immersive VR action-observation could help people with Parkinson's move faster and perform daily tasks with less slowness.
How similar studies have gone: Single-session action-observation studies have shown short-term improvements in bradykinesia, but long-term use of patient-specific immersive VR is novel and less tested.
