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.
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…
-Presence of residual upper extremity hemiparesis, defined as any of the following: Fugl Meyer Upper Extremity Score \<66, Wolf Motor Function Test Score \<70, Affected hand performance on the 9-Hole Peg Test \>= 10% worse than unaffected hand, Affected hand pinch, key, or power grip performance \>= 10% worse than unaffected hand, * Occurrence of ischemic or hemorrhagic stroke \>= 6 months before participation * Mini Mental State Exam score \> 24 * Willingness and ability to provide informed consent * No history of neurological disease and/or neurological injury other than stroke * No TMS con…
Single-pulse TMS will be applied to the lesioned hemisphere during brain activity patterns associated with strong residual corticospinal tract activation and random brain activity patterns.
