Effects of High-Frequency rTMS on Cortical Motor Mapping in Stroke Patients With Severe Upper Limb Impairment (MAP2024SJD)

The goal of this clinical trial is to learn if a single session of high-frequency repetitive transcranial magnetic stimulation (rTMS) can increase cortical motor activity in stroke patients with severe upper limb impairment. The main question it aims to answer is: Does one session of high-frequency rTMS increase the number of motor evoked potential (MEP)-positive points in the cortical motor map of the affected hemisphere compared to sham stimulation? Researchers will compare high-frequency rTMS (10 Hz, 600 pulses) applied over the affected motor cortex to sham stimulation to see if rTMS increases detectable cortical motor responses in patients who have little or no voluntary hand movement after stroke. Participants will: Undergo a cortical motor mapping assessment before the intervention. Receive either one session of real rTMS or sham stimulation, depending on their randomly assigned group. Undergo a second cortical motor mapping assessment immediately after the intervention.
