Outcome Measures

Primary Outcomes (1)

  • Relative Power of Event Related Desynchronization in µ et beta EEG bands of healthy controls and stroke participants

    The relative increase of Event Related Desynchronization (ERD) relative power sensorimotor rhythms (µ et beta bands) in EEG during the last session of NeuroFeedBack in the motor cortex, between motor imagery and rest, measured in microvolt

    throught study completion, in the 5th week after the onset of the experiment for each participant

Study Arms (3)

TEST 1: Visual virtual Conditions

OTHER

* 50 subjects (30 healthy volunteers and 20 patients after stroke) * 3 different situations of vibration applications, without EGG neurofeedback session

Other: Visual virtual Conditions

TEST 2: Standard EEG

OTHER

* 20 subjects (healthy volunteers) * 3 separate electroencephalographic recording conditions without Neurofeedback

Other: Standard EEG

TEST 3: Neurofeedback Training Stroke Patients

OTHER

* 26 patients after stroke * 12 neurofeedback sessions spread over 6 weeks according to the feedback modality that will be drawn (visual or visuo-vibratory)

Other: Neurofeedback Training Stroke Patients

Interventions

The objective is to evaluate if certain virtual visual conditions can increase the illusion of movement induced by the tendon vibration of the upper limb. Thirty healthy volunteers and 20 post-stroke subjects will test 3 different situations of vibration applications, with no EEG Neurofeedback session. It will be applied to the subject (healthy and post-stroke) according to a randomized order a vibrator for a few minutes on his non-dominant (or deficit) hand hidden from view, with a screen representing a static virtual hand, then a vibrator on his hand hidden with a screen representing an animated virtual hand, then a vibrator on his hand hidden with a screen representing an empty background.

Also known as: 3 different situations of vibration applications, without EGG neurofeedback session
TEST 1: Visual virtual Conditions

Twenty healthy volunteers test 3 separate electroencephalographic recording conditions without Neurofeedback. It will be applied to the subject an EEG headset recording brain activity during the application of vibration stimulation producing the illusion of movement on the non-dominant hand or during a task Mental imagery of the upper limb, or during the joint application of vibratory stimulation and a mental imaging task on the affected upper limb in a randomized order.

Also known as: 3 separate electroencephalographic recording conditions without Neurofeedback
TEST 2: Standard EEG

The post-stroke subject is evaluated on clinical tests (FMA, ARAT, MAL, NHPT, Finger Tapping test) during the first visit. Then, he performs 12 sessions of NFB (on his deficit member) lasting 45 minutes, spread over 6 weeks, depending on the feedback modality that has been drawn randomly (visual or visuo-vibratory). A second visit after the first NFB session and a third visit after the last NFB session evaluates the motor skills of the trained upper limb (FMA, ARAT, MAL, NHPT, Finger Tapping test) and a satisfaction questionnaire is given to the subject for evaluate tolerance and satisfaction with the feedback modality assigned. Evaluation of changes of EEG sensorimotor rhythms at the end of the program.

Also known as: 12 neurofeedback sessions spread over 6 weeks according to the feedback modality that will be drawn (visual or visuo-vibratory)
TEST 3: Neurofeedback Training Stroke Patients

Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Healthy Volunteers : Major (age greater than or equal to 18 years) and under 80 years; Free, informed and written consent signed by the volunteer; Absence of clinical neurological antecedents that can interact with the achievement of the motor task or with the EEG signal.
  • Patients after stroke : Major (age greater than or equal to 18 years) and under 80 years;Ischemic or unilateral cerebral hemorrhagic hemorrhagic attack;Stroke dating back more than 6 months (considered as a delay where recovery of the upper limb to wait is less with conventional rehabilitation);Mild to severe upper limb deficiency: FMA-EU score ≤ 60; Free, informed and written consent signed by the patient or a member of his entourage (in the case of a patient able to understand the information and to express his / her consent but presenting motor difficulties leading to an invalid signature).

You may not qualify if:

  • Healthy Volunteers : major persons subject to legal protection, persons deprived of their liberty
  • Patients after stroke : Ischemic or hemorrhagic involvement of posterior fossa (brainstem, cerebellum);Complete motor deficiency of the upper limb (FMA-UE = 0);Epicritic and proprioceptive anesthesia;Understanding difficulties limiting participation in the study;Major persons subject to legal protection, persons deprived of their liberty
