Safety and Efficacy of Early Brain-Computer Interface Training After Reperfusion Therapy in Acute Ischemic Stroke (RT-BCI)

8 maggio 2026 aggiornato da: Shandong Provincial Hospital

This is a multicenter, prospective, randomized controlled trial designed to evaluate the efficacy, safety, and feasibility of early EEG-based non-invasive brain-computer interface (EEG-BCI) training as an add-on to standard early rehabilitation in patients with acute ischemic stroke (AIS) after reperfusion therapy. Eligible participants are adults aged 18 to 80 years with unilateral limb motor dysfunction after intravenous thrombolysis (IVT) and/or mechanical thrombectomy (MT). Participants will be randomized to receive either standard early rehabilitation plus closed-loop EEG-BCI dual-module virtual hand and gait training, or standard early rehabilitation alone.

The EEG-BCI intervention includes upper-limb virtual hand training and lower-limb gait/ankle dorsiflexion training, delivered twice daily for approximately 20 minutes per session over 5 consecutive days. The primary outcome is the change in Fugl-Meyer Assessment for Upper Extremity (FMA-UE) score from baseline (T0) to Day 30. Secondary outcomes include upper- and lower-limb motor function, ambulation, neurological status, disability, and activities of daily living. Safety and feasibility outcomes will also be assessed.

Descrizione

Inclusion Criteria:

  • 1. Age 18 to 80 years.
  • 2. Acute ischemic stroke (AIS) treated with reperfusion therapy, including intravenous thrombolysis (IVT) and/or mechanical thrombectomy (MT); for participants undergoing MT, successful recanalization during the procedure defined as eTICI 2b-3.
  • 3. Meets the protocol-defined clinical stability criteria for the corresponding treatment pathway (see Section 4.3).
  • 4. Unilateral limb motor dysfunction on the same side as the dominant hand.
  • 5. Fugl-Meyer Assessment for Upper Extremity (FMA-UE) score of 10 to 50 at T0.
  • 6. Pre-stroke modified Rankin Scale (mRS) score <= 2.
  • 7. Written informed consent provided by the participant and ability to comply with training and follow-up; if necessary, consent may be provided by a legally authorized representative.

Exclusion Criteria:

  • 1. Imaging-confirmed symptomatic intracranial hemorrhage (sICH), or bleeding risk considered unacceptable by the investigator and requiring a change in treatment strategy.
  • 2. Overt progressive neurological deterioration or need for urgent intervention, making training inappropriate, such as an increase in National Institutes of Health Stroke Scale (NIHSS) score of >=4 from a prior assessment with cause not yet clarified or stabilized.
  • 3. Severe disturbance of consciousness, severe aphasia or neglect, or significant cognitive impairment that would prevent completion of BCI training tasks or primary outcome assessment.
  • 4. Bilateral significant motor impairment, such as brainstem or bilateral lesions, or pre-existing moderate-to-severe disability of the contralateral upper or lower limb, which would interfere with training or interpretation of assessments under the unilateral impairment framework.
  • 5. Severe comorbidity or unstable vital signs, including but not limited to unstable arrhythmia, severe heart failure or respiratory failure, active severe infection or sepsis, or severe hepatic or renal failure, such that the investigator judges the participant unable to safely complete training and follow-up.
  • 6. Severe scalp skin damage or infection, or any other condition preventing safe use of the EEG electrode cap.
  • 7. Frequent seizures within 7 days before randomization, or seizure risk considered unacceptable by the investigator.
  • 8. Pregnancy or breastfeeding.
  • 9. Participation in another interventional clinical study that may affect the outcomes of this study, or any other condition that, in the investigator's judgment, makes the participant unsuitable for enrollment.

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Change in Fugl-Meyer Assessment for Upper Extremity (FMA-UE) score
Lasso di tempo: Baseline (T0), Day 30
Change is calculated as the Day 30 FMA-UE score minus the baseline (T0) FMA-UE score. Higher positive values indicate greater improvement in upper-extremity motor function. T0 is defined as 48 hours after IVT for the IVT-only pathway, and Day 5 (120 ± 24 hours) after MT for the MT ± IVT pathway.
