This thesis will explore the use of implanted brain-computer interfaces (BCIs) for motor rehabilitation in stroke patients. The project leverages Clinatecapos;s WIMAGINE technology, which measures brain activity through electrocorticography (ECoG) to accurately decode patientsapos; motor intentions. Integrating this technology into a rehabilitation protocol is expected to enhance residual motor abilities through neural plasticity. In this context, the thesis aims to implement the rehabilitation protocol with Clinatecapos;s technical and clinical teams and to characterize motor recovery in patients during training sessions, both behaviorally and neurally. The study will include a review of current BCI-assisted rehabilitation approaches, the development of tools to monitor motor progress and measure neural plasticity indicators, as well as the optimization of rehabilitation sessions based on patientsapos; motor performance. Motor and neural progression will be studied longitudinally over nine months, with an extended two-year follow-up to assess the durability of the benefits. Supported by the French Ministry of Research and the EU, this project offers a unique opportunity to establish the foundations of a new post-stroke rehabilitation paradigm using implanted BCIs.
