NCT05152108

Brief Summary

HYBIS project aims to develop an innovative and unique hybrid Brain-Computer Interface (BCI) system. This BCI system is envisioned as a novel tool for targeted reinforcement of sensory motor coupling, specifically dedicated for upper-limb post-stroke rehabilitation.

Outcome Measures

Primary Outcomes (2)

  • Electrotactile BCI system accuracy

    Electrotactile BCI system accuracy is a measure of feasibility of the prototype device. Accuracy \[0 -100 %\] of classification of user's mental strategy (tactile attention task towards one of the two electrical stimulation hotspots), where higher values of accuracy are related to better system control.

    within 30 minutes after experimental session

  • Motor Imagery BCI system accuracy

    Motor Imagery BCI system accuracy is a measure of feasibility of the prototype device. Accuracy \[0 - 100 %\] of classification between rest and imaginary movement in a cue-based manner, , where higher values of accuracy are related to better system control.

    within 30 minutes after experimental session

Secondary Outcomes (2)

  • Fugl Meyer sensory score for upper extremity

    immediately after experimental session

  • NASA-TLX

    within 30 minutes after experimental session

Study Arms (1)

Stroke patients

EXPERIMENTAL

Experimental group of stroke survivors for testing the feasibility of a BCI system

Device: BCI feasibility test

Interventions

Testing the feasibility of BCI device by determining the accuracy of BCI control

Stroke patients

Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • age over 18 years old at the time of enrolment
  • history of cerebrovascular insult verified by computerized tomography or magnetic resonance imaging;
  • stoke occurred not more than 6 months prior to study enrolment;
  • subject need to be medically and neurologically stable determined by medical history and documented neurological examination;

  • severe spasticity defined as Ashworth scale score of 4 in the affected arm;
  • contraindication to stimulation system placement;
  • nursing a child;
  • pregnancy.
