Estimulação Transcraniana de Interferência Temporal Domiciliar com Supervisão Remota sobre os Sintomas Motores na Doença de Parkinson

Estimulação Transcraniana de Interferência Temporal em Ambiente Domiciliário com Supervisão Remota sobre os Sintomas Motores na Doença de Parkinson: Protocolo para um Ensaio Randomizado Controlado Duplamente Cego

The goal of this clinical trial is to learn if home-based temporal interference stimulation (TIS) works to improve motor symptoms in people with Parkinson's disease (PD). It will also learn about the safety of this treatment. The main questions it aims to answer are:

  1. Does home-based TIS improve movement problems such as slow movement, stiffness, and walking difficulty?
  2. Are the effects maintained after the treatment ends?
  3. What medical problems (adverse events) occur during treatment? Researchers will compare active TIS to a sham treatment (a look-alike procedure that does not deliver active stimulation) to see if TIS works.

Participants will:

  1. Receive active TIS or sham stimulation once a day for 4 weeks at home under remote supervision
  2. Visit the clinic at specific time points for movement assessments
  3. Complete online questionnaires about symptoms and quality of life

Armas e Intervenções

Grupo de Participantes / Braço
Intervenção / Tratamento
Experimental: TIs-Group

Participants in this arm will receive active transcranial temporal interference stimulation targeting the internal globus pallidus over a four-week intervention period.

Transcranial temporal interference stimulation (TIS) is a noninvasive brain stimulation technique that delivers two high-frequency alternating currents through scalp electrodes to generate a low-frequency interference field in deep brain regions. In this study, TIS targets the internal globus pallidus (GPi) to modulate neural activity in people with Parkinson's disease. Participants will receive one stimulation session per day, seven days per week, for four weeks in a home-based setting under real-time remote supervision.

The electrode placement is based on a standard 10-10 electroencephalography (EEG) system. For stimulation targeting the right GPi, electrode pairs will be positioned at CP3-CP6 and F3-F6; for stimulation targeting the left GPi, electrode pairs will be positioned at CP4-CP5 and F4-F5.

The sham TIS condition uses the same setup and procedures but does not deliver effective stimulation, thereby maintaining blinding.

Comparador Falso: Sham-TIs Group

Participants in this arm will receive sham transcranial temporal interference stimulation using the same electrode placement and experimental setup as the active intervention. The sham procedure consists of 28 sessions delivered over a four-week period, without therapeutic stimulation.
