Towards Real-time Personalized Brain State-dependent TMS to Enhance Poststroke Hand Rehabilitation
Sara Hussain
Summary
Transcranial magnetic stimulation (TMS) interventions could feasibly strengthen residual corticospinal tract (CST) connections and enhance recovery of paretic upper extremity function after stroke. This project will test whether personalized brain state-dependent TMS can activate the residual corticospinal tract better than standard TMS, and evaluate the relationship between this activation and upper extremity motor impairment.
Description
Transcranial magnetic stimulation (TMS) interventions could feasibly strengthen residual corticospinal connections and enhance recovery of paretic upper extremity function after stroke. To maximize the therapeutic effects of such interventions, they must be delivered during poststroke brain activity patterns during which TMS best activates the residual corticospinal tract and enhances neural transmission within it (i.e., brain state-dependent TMS). In this study, the investigators will test the feasibility of real-time, personalized brain state-dependent TMS in chronic stroke survivors. The in…
