Temporalisen interferenssistimulaation vaikutus motorisiin oireisiin Parkinsonin taudissa

torstai 28. toukokuuta 2026 päivittänyt: Yu Liu, Shanghai University of Sport

Ei-invasiivisen syvän aivostimulaation vaikutukset ja mekanismit Parkinsonin tautia sairastavilla potilailla

Tämän kliinisen tutkimuksen tavoitteena on selvittää, voiko aivostimulaatiotyyppi, jota kutsutaan transkraniaaliseksi temporaaliseksi interferenssistimulaatioksi (TIS) sisemmässä pallidumissa (GPi), auttaa parantamaan Parkinsonin tautia sairastavien ihmisten liikeoireita. Tutkimus tarkastelee myös, miten TIS muuttaa näihin parannuksiin liittyvää aivoaktiivisuutta.

Tutkimuksen pääkysymykset ovat:

  • Kuinka paljon toistuvat TIS-sessiot voivat parantaa Parkinsonin tautia sairastavien ihmisten liikeoireita?
  • Voivatko nämä parannukset kestää jopa kahden kuukauden ajan hoidon päätyttyä?
  • Mitkä muutokset aivoaktiivisuudessa tapahtuvat parannusten myötä?

Tutkijat vertailevat aktiivista TIS:ää saaneita henkilöitä niihin, jotka saavat sham (plasebomainen) stimulaatiota, nähdäkseen, johtaako aktiivinen TIS parempiin liiketuloksiin.

Osallistujat:

  • Saavat 10 aktiivisen tai sham-TIS-sessiota kahden viikon aikana
  • Suorittavat liike-arvioinnit kahden viikon hoidon aikana sekä uudelleen 2, 4 ja 8 viikon kuluttua
  • Suorittavat aivoaktiivisuusarvioinnit ennen kahden viikon hoitojaksoa ja sen jälkeen

Aseet ja interventiot

Osallistujaryhmä / Arm
Interventio / Hoito
Kokeellinen: TIS-ryhmä
Tämän ryhmän osallistujat saavat aktiivista transkraniaalista temporaalista interferenssistimulaatiota, joka kohdistuu sisäiseen pallidum-palloseen kahden viikon interventiojakson aikana.
Laite: Transkraniaalinen temporaalinen interferenssistimulaatio (TIS)
Transkraniaalinen temporaalinen interferenssistimulaatio (TIS) on ei-invasiivinen aivostimulaatiotekniikka, joka välittää kaksi korkeataajuista vaihtovirtaa päänahkaelektrodien kautta luodakseen matalataajuisen interferenssikentän syvissä aivoalueissa. Tässä tutkimuksessa TIS kohdistuu sisäiseen pallidum-globukseen (GPi) moduloidakseen hermostollista aktiivisuutta Parkinsonin tautia sairastavilla henkilöillä. Osallistujat saavat 10 stimulaatiosessiota kahden viikon aikana. Valetutkimus-TIS-kunto käyttää samaa asetusta, mutta soveltaa matalataajuisia virtoja luomatta interferenssikuviota.
Huijausvertailija: 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.

Aikaikkuna
Change From Baseline in the Home Diary Assessment of Motor States (Medication-ON Without Dyskinesia)
Aikaikkuna: 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.
