• Conditions: Hemiparetic Stroke

• Registration Number: NCT06931509
• Lead Sponsor: Centre Hospitalier Universitaire de Saint Etienne

Brief Summary

Mental imagery is a rehabilitation technique for stroke patients, involving the mental representation of movement. Recent technical advancements have enabled the use of visual, proprioceptive, and mixed feedback to enhance motor stimulation. Currently, all post-stroke patients receive these techniques indiscriminately. This study aims to demonstrate differences in the integration of visual and proprioceptive feedback in stroke patients and understand the determinants based on the affected brain area.

Patients with motor disabilities will perform motor imagery tasks with various feedback types while their cortical activity is recorded using EEG. EEG data for each type of feedback will be correlated with the lesion area in order to better understand the ongoing mechanisms.
