NCT07361250

Brief Summary

This is a single-center, prospective, double-blind, randomized controlled trial to evaluate the efficacy and safety of transcranial temporal interference stimulation targeting the subthalamic nucleus in patients with Parkinson's disease. It plans to enroll 20 eligible participants who will be randomly assigned in a 1:1 ratio to either the active TIS stimulation group or the sham stimulation group.

Outcome Measures

Primary Outcomes (1)

  • Change in Score on Part III (Motor Examination) of the Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS)

    The motor function of patients was assessed using Part III of the Movement Disorder Society-Unified Parkinson's Disease Rating Scale (MDS-UPDRS-III), which has a total score range of 0 to 132. In this scale, a higher score indicates greater severity of motor symptoms and therefore a worse outcome, with 0 representing no impairment and 132 representing the most severe impairment. Changes in the score reflect the degree of improvement in motor function.

    Baseline (before treatment), immediately after the 1st(day1), 5th(day3), and 9th(day5) stimulation sessions (each session lasts for 30 min), and at the two-week and four-week follow-ups after the completion of treatment.

Secondary Outcomes (9)

  • MDS-UPDRS Scale Part I Non-Motor Function Score Changes

    Baseline (before treatment), immediately after the 9th(day5) stimulation sessions (each session lasts for 30 min), and at the two-week and four-week follow-ups after the completion of treatment.

  • MDS-UPDRS Scale Part II: Activities of Daily Living Score Changes

    Baseline (before treatment), immediately after the 9th(day5) stimulation sessions (each session lasts for 30 min), and at the two-week and four-week follow-ups after the completion of treatment.

  • MDS-UPDRS Scale Part IV: Motor Fluctuations, Dyskinesias, and Dystonia Score Changes

    Baseline (before treatment), immediately after the 9th(day5) stimulation sessions (each session lasts for 30 min), and at the two-week and four-week follow-ups after the completion of treatment.

  • Change in Score on the 39-item Parkinson's Disease Questionnaire (PDQ-39)

    Baseline (before treatment), immediately after the 9th(day5) stimulation sessions (each session lasts for 30 min), and at the two-week and four-week follow-ups after the completion of treatment.

  • Change in Score on the Hamilton Depression Rating Scale (HAMD)

    Baseline (before treatment), immediately after the 9th(day5) stimulation sessions (each session lasts for 30 min), and at the two-week and four-week follow-ups after the completion of treatment.

  • +4 more secondary outcomes

Other Outcomes (2)

  • The incidence of SAE

    From the first stimulation session until the end of the study follow-up period (each stimulation session lasts for 30 minutes; total study duration including follow-up is 5 weeks). SAEs will be monitored and recorded continuously throughout this period.

  • All-cause mortality

    1month after randomization

Study Arms (2)

Active TIS stimulation

EXPERIMENTAL

Participants in this group will receive transcranial temporal interference stimulation targeting the subthalamic nucleus using a frequency pair of 2000 Hz and 2130 Hz. Stimulation will be delivered twice daily at the same time for 30 minutes per session over five consecutive days(only once on the 5th day). Stimulation intensity will be individually titrated starting from a low level and gradually increased to the maximum tolerable level. All treatments will be administered during the participant's medication "on" state.

Device: NervioX-1000

Sham stimulation

SHAM COMPARATOR

Participants in this group will receive sham stimulation using a frequency pair of 2000 Hz and 2000 Hz. Stimulation will be administered twice daily for 30 minutes per session over five consecutive days(only once on the 5th day) during the participant's medication "on" state, with current intensity individually titrated in the same manner as the active group. The sham protocol includes cutaneous sensation simulation during a 30-second ramp-up and ramp-down phase to maintain participant blinding, but does not generate an effective interference field in the deep brain target.

Device: NervioX-1000

Interventions

All participants will receive individualized T1-weighted MRI scans for computational modeling to determine optimized electrode placement and stimulation parameters for transcranial temporal interference stimulation targeting the subthalamic nucleus. The stimulation protocol is designed to generate a focal 130 Hz interference field in the target region while minimizing cortical activation. Parameters including electrode positions and current intensity are customized based on each participant's unique neuroanatomy to ensure precise and tailored neuromodulation.

Masking Details
This is a double-blind trial where participants, investigators administering the intervention, and outcome assessors are blinded. Due to the operation of the Temporal Interference Stimulation device, only the instrument operator administering the experimental stimulation in this experiment is non-blinded. Identical stimulation procedures are used for both groups, with the sham group receiving a non-effective frequency pair.
