# Improve diagnostic imaging for tremor

**Goal (in five words):** Improve diagnostic imaging for tremor

**Official Title:** Preparation and Feasibility of Exams for Expected Studies (PRELUDE)

**Trial ID:** [NCT05698810](https://clinicaltrials.gov/study/NCT05698810)

## Key Facts

- **Phase:** NA
- **Status:** RECRUITING
- **Study Type:** INTERVENTIONAL
- **Sponsor:** University Hospital, Grenoble
- **Target Enrollment:** 150 participants
- **Start Date:** 2023-03-20
- **Completion Date:** 2033-03-20
- **Conditions:** Healthy Volunteers, Parkinson's Disease Patients, Para/Tetraplegic Patients
- **Interventions:** CE marked Medical Device MagnetoEncephaloGraphy (MEG) usability, CE marked Medical Device Magnetic Resonance Imaging (MRI) usability, CE marked Medical Device ElectroEncephaloGraphy (EEG) usability, CE marked Medical Device ElectroCardioGraphy (ECG) usability
- **Intervention Types:** OTHER

## Summary For Families

PRELUDE wants to make sure standard brain and heart exams can be done comfortably and reliably in people with Parkinson's, healthy volunteers, and people with para- or tetraplegia before larger studies. Volunteers will complete CE marked MEG, MRI, EEG and ECG sessions so the team can test usability, tolerability and data quality; MEG records tiny magnetic fields from brain activity, EEG records electrical brain waves, MRI gives detailed images of brain structure and function, and ECG tracks heart rhythm. The trial is enrolling adults 18 and older who can give informed consent and are affiliated with a social security scheme, while pregnant or breastfeeding people, those under legal protection, or otherwise excluded by the protocol are not eligible.

## Eligibility

- **Minimum age:** 18 Years
