Interventional study with minimal risks and constraints, prospective, monocentric.
Many patients with stroke have a severe motor deficit in the upper limb impacting their independence. Electroencephalogram (EEG) Neurofeedback is a re-education technique that improves cerebral plasticity and motor gain in these people during the chronic phase of stroke. The visual feedback usually used tends to diminish the subject's attentional resources, while the proprioceptive feedbacks appear to be more effective on cortical excitability. Vibration feedback inducing movement illusion has been shown to be effective in healthy subjects, but has not been tested in people with stroke.

| Visual virtual Conditions | Other | 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. |

| 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 |

| Standard EEG | Other | 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. |

|
| Neurofeedback Training Stroke Patients | Other | 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. |
