While deep brain stimulation (DBS) is effective, its invasive nature limits its application in early-stage patients. Temporal interference stimulation (TIS) is a novel non-invasive technique that can target deep brain structures like the globus pallidus internus (GPi) by using high-frequency electric fields.\n\nThis study aims to evaluate the clinical value and underlying mechanisms of TIS in PD patients. The research is divided into two phases: Phase A investigates the immediate regulatory effects of 130 Hz and 40 Hz TIS on brain networks using concurrent fMRI-TIS. Phase B is a randomized, double-blind, sham-controlled trial to assess the long-term efficacy and safety of a 2-week TIS intervention on both motor and non-motor symptoms. The results will help clarify how TIS modulates deep brain networks and its potential as a non-invasive therapy for PD.",[82],"PARKINSON DISEASE (Disorder)",[84,85,86,87],"Temporal Interference Stimulation (TIS)","Functional Magnetic Resonance Imaging (fMRI)","Non-invasive Brain Stimulation (NIBS)","Neuromodulation","NOT_YET_RECRUITING","2026-03-20",{"date":91,"type":92},"2026-03-24","ACTUAL",{"date":89,"type":76},{"date":95,"type":76},"2027-03-31",{"name":5,"class":6},1]
