Temporale Interferenzstimulation bei motorischen Symptomen der Parkinson-Krankheit
Wirkungen und Mechanismen der nicht-invasiven tiefen Hirnstimulation bei Patienten mit Parkinson-Krankheit
Ziel dieser klinischen Studie ist es herauszufinden, ob eine Art der Gehirnstimulation namens transkranielle zeitliche Interferenzstimulation (TIS) des inneren Globus pallidus (GPi) helfen kann, Bewegungssymptome bei Menschen mit Parkinson-Krankheit zu verbessern. Die Studie wird auch untersuchen, wie TIS die mit diesen Verbesserungen verbundene Gehirnaktivität verändert.
Die Hauptfragen, die diese Studie beantworten soll, sind:
- Wie stark können wiederholte TIS-Sitzungen Bewegungssymptome bei Menschen mit Parkinson-Krankheit verbessern?
- Können diese Verbesserungen bis zu zwei Monate nach Beendigung der Behandlung anhalten?
- Welche Veränderungen der Gehirnaktivität treten zusammen mit den Verbesserungen auf?
Die Forscher werden Personen, die aktive TIS erhalten, mit denen vergleichen, die Schein- (placeboähnliche) Stimulation erhalten, um festzustellen, ob aktive TIS zu besseren Bewegungsergebnissen führt.
Die Teilnehmer werden:
- 10 Sitzungen aktiver oder scheinbarer TIS über zwei Wochen erhalten
- Bewegungsbewertungen während der zweiwöchigen Behandlung und erneut 2, 4 und 8 Wochen danach durchführen
- Gehirnaktivitätsbewertungen vor und nach der zweiwöchigen Behandlung durchführen

Intervention / Behandlung |
|---|---|
|
Experimental: TIS Gruppe
Die Teilnehmer in diesem Arm erhalten über einen zweiwöchigen Interventionszeitraum eine aktive transkranielle temporale Interferenzstimulation, die auf den inneren Globus pallidus abzielt.
|
Transkranielle temporale Interferenzstimulation (TIS) ist eine nicht-invasive Hirnstimulationstechnik, bei der zwei hochfrequente Wechselströme durch Skalpelektroden geleitet werden, um ein niederfrequentes Interferenzfeld in tiefen Hirnregionen zu erzeugen.
In dieser Studie zielt TIS auf den inneren Globus pallidus (GPi) ab, um die neuronale Aktivität bei Menschen mit Parkinson-Krankheit zu modulieren.
Die Teilnehmer erhalten über zwei Wochen hinweg 10 Stimulationssitzungen.
Die Schein-TIS-Bedingung verwendet denselben Aufbau, wendet jedoch niederfrequente Ströme an, ohne ein Interferenzmuster zu erzeugen.
|
|
Schein-Komparator: Sham Group
Participants in this arm will receive sham transcranial temporal interference stimulation using the same electrode placement and experimental setup as the active intervention.
However, both electrode pairs delivered currents at 2000 Hz without a frequency offset, resulting in a flat interference envelope while maintaining similar scalp sensations.
The sham procedure consists of 10 sessions delivered over a two-week period, without therapeutic stimulation.

Change From Baseline in the Home Diary Assessment of Motor States (Medication-ON Without Dyskinesia)
Zeitfenster: Baseline, weekly averages during weeks 1 and 2 of the intervention
|
The motor state will be recorded by participants using a self-completed home diary during waking hours in 30-minute intervals from awakening until bedtime. For each interval, participants will record one of the following motor states: ON with good control, ON with mild dyskinesia, ON with severe dyskinesia, or OFF. Baseline assessment will be defined as the average percentage of waking time spent in ON states over three consecutive days immediately prior to the intervention. The 1-week assessment will be defined as the average percentage of waking time spent in ON states over the five intervention days of the first intervention week, and the 2-week assessment as the average over the five intervention days of the second intervention week. The outcome measure is defined as the percentage of total recorded waking time spent in ON states, calculated from the home diary data. A higher percentage of time spent in ON states indicates milder motor symptoms and better motor control. |
