Clinical Trail of Transcranial MR-guided Focused Ultrasound in the Treatment of Motor Symptoms in Patients With Parkinson' Disease

NCT06639945 | Completed

• 1 other identifier: XHEC-C-2024-125-2-1
• Study Type: interventional
• Target: 10
• Locations: 1 country
• Sites: 1

Brief Summary

Randomized, double-blind, self-cross-over control (After the first visit, patients are divided into two groups, randomly receiving real stimulation/placebo stimulation. 14 days later, during the second visit, a cross-over occurs: patients who received real stimulation in the first visit will receive placebo stimulation in the second visit, and vice versa. The grouping situation remains blinded for the patients, EEG analysis, and video analysis.)

Conditions

Parkinson Disease, Idiopathic

Outcome Measures

Primary Outcomes (1)

• UPDRS-III

  Change in Unified Parkinson's Disease Rating Scale (MDS-UPDRS) total score of part III. The part III of the MDS-UPDRS assess motor function in best on phase. The score range is 0-132, where a higher score means more severe motor impairment.

  Beginning and end of each experimental session

Secondary Outcomes (1)

• cortical activation detected by scalp EEG

  From baseline (pre-sonication) to 10 minutes post-sonication

Study Arms (2)

Verum stimulation followed by Sham stimulation

EXPERIMENTAL

Device: transcranial MR-guided focused ultrasound

Interventions

transcranial MR-guided focused ultrasound DEVICE

MRI-guided transcranial focused ultrasound (MRgFUS) combines magnetic resonance imaging (MRI) with focused ultrasound to target specific areas in the brain non-invasively. MRgFUS allows for treatment without surgical incisions, leading to fewer risks and a quicker recovery. MRI provides real-time imaging that helps precisely locate and treat affected brain regions, such as the thalamus or globus pallidus.The procedure allows for continuous monitoring of the treatment effects, enabling adjustments as needed.
