Brief Summary:
This research project will investigate neurofeedback training in stroke rehabilitation during which patients receive feedback in real time from their brain activity measured with ElectroEncephaloGraphy (EEG). The investigators hypothesize that the feedback training allows to internally stimulate brain motor networks in order to promote functional recovery of the hand.

Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: EEG-based Mental Imagery Feedback in Stroke Patients With Severe Hand Dysfunction
Actual Study Start Date : August 5, 2019
Actual Primary Completion Date : January 17, 2020
Actual Study Completion Date : January 17, 2020

Arm Intervention/treatment
Experimental: Mental imagery neurofeedback training
Complete intervention with mental imagery neurofeedback training. Patients recruited by physioterapists who underwent baseline evaluations with clinical tests, fMRI and EEG measurements. Patients will after intervention perform clinical tests, fMRI, and EEG measurements to evaluate outcomes of intervention.
Device: Mental imagery neurofeedback training
Mental Imagery (MI)-neurofeedback training, 2-3 hours, 3 times/week for 4 weeks.

  2. Change of EEG alpha and beta activity [ Time Frame: Up to 7 weeks ]
    Brain motor network activity reflected in neurofeedback signal

  3. Change of fMRI BOLD activity [ Time Frame: Up to 7 weeks ]
    Brain motor network activity

Secondary Outcome Measures :
  1. Change of monofilament test score [ Time Frame: Up to 10 weeks ]
    Two point discrimination and monofilament test for sensory function

  2. Change of box and block test score (0-150) [ Time Frame: Up to 10 weeks ]
    Gross manual dexterity

  3. Change of JAMAR® digital Hand Dynamometer scores (0-90) [ Time Frame: Up to 10 weeks ]
    Grip strength

  4. Change of visuomotor force-tracking task scores [ Time Frame: Up to 10 weeks ]
    Quantification of timing and precision aspects of force grip modulation

  5. Change of stroke Impact Scale 16 scores (15-80 points) [ Time Frame: Up to 10 weeks ]
    Activity limitations related to physical function
