Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Individualized stimulation group
Patients receive five sessions of individualized stimulation obtained from brain image-based transcranial direct stimulation simulation. The simulator generates the electrode's location on the scalp.
Enhed: Transkraniel jævnstrømsstimulering
Transkraniel jævnstrømsstimulering er en form for ikke-invasiv neuromodulation, der bruger konstant og lav jævnstrøm leveret via elektroder i hovedbunden.
Aktiv komparator: Conventional stimulation group
Patients receive five sessions of conventional stimulation with electrodes over C3 and C4 based on the 10-20 system.
Enhed: Transkraniel jævnstrømsstimulering
Transkraniel jævnstrømsstimulering er en form for ikke-invasiv neuromodulation, der bruger konstant og lav jævnstrøm leveret via elektroder i hovedbunden.
Sham-komparator: Sham stimulation group
Patients receive five sessions of sham stimulation with electrodes over C3 and C4 based on the 10-20 system.

Hvad måler undersøgelsen?

Primære resultatmål

Resultatmål
Foranstaltningsbeskrivelse
Tidsramme
Changes in motor evoked potential
Tidsramme: Baseline, 1 day (immediately after one brain stimulation session) and about 14 days (immediately after five brain stimulation sessions)
Resting motor threshold (rMT), amplitude, and latency of motor evoked potential in the first dorsal interosseous muscle are measured. These outcomes are measured by transcranial magnetic stimulation over the motor hotspot. The rMT is defined as the minimum stimulus intensity that produced a minimal motor evoked response at rest. The amplitude means peak to peak of the muscle response. The latency is defined as the time point from the onset of the stimulus to the onset of MEP.
Baseline, 1 day (immediately after one brain stimulation session) and about 14 days (immediately after five brain stimulation sessions)
