Pedunculopontine Nucleus Transcranial Ultrasound Stimulation as a Treatment of Freezing of Gait in Parkinson's Disease (NCT07695233)

๐ŸŸข Recruiting Observational / Diagnostic โš™๏ธ Medical Device Protocol Sponsor: Robert Chen

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

This study is investigating the use of transcranial ultrasound stimulation (TUS) on the Pedunculopontine nucleus (PPN) in changing freezing of gait in people with Parkinson's disease. The PPN is noted to be involved in voluntary movements, locomotion, and muscle tone. This will be assessed by patient-reported outcomes and analyzing the gait. The study will also investigate the effects of the stimulation on the PPN and surrounding connectivity by using magnetic resonance imaging (MRI).
