About this trial

This is an interventional device feasibility trial for Stroke

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  • 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;
  • ability to understand, communicate and cooperate with the research team;
  • ability to sit for at least 45 minutes and the ability to adhere to the study rehabilitation protocol.

Exclusion Criteria:

  • any neurologic condition (beyond the stroke) or physical condition that impaired function of the affected arm
  • a substantial cardiopulmonary or metabolic disorder or other major medical complication;
  • history of seizures;
  • moderate to severe hemispatial neglect or anosognosia involving the affected arm;
  • severe sensory deficit;
  • inability to understand, cooperate, and adhere to the study procedures;
  • severe spasticity defined as Ashworth scale score of 4 in the affected arm;
  • contraindication to stimulation system placement;
  • nursing a child;
  • pregnancy.

Arm Description

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

Outcomes

Primary Outcome Measures

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.
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.

Secondary Outcome Measures

Fugl Meyer sensory score for upper extremity
Fugl Meyer sensory score for upper extremity assesses the degree of sensory impairment in the upper arm. Sensation score ranges from 0 to 12 points, divided into 4 points for light touch and 12 points for position sense. Individual items pertaining to the light touch sensation of the upper arm/ forearm and palmary surface of the hand and to the position of the shoulder/ elbow/ wrist/ thumb (IP-joint) are scored on a 3-point ordinal scale and summed for a maximum possible score of 12. The higher score is considered to represent a less sensory deficit of the subject
NASA-TLX
NASA Task Load Index (NASA-TLX) method assesses workload on six scales for different aspects: mental demand, physical demand, temporal demand, performance, effort, and frustration on a 21-point scale. A higher rating represents higher workload.
