Experimental condition (personalized stimulation)
Each 100 Hz triplet is triggered by the real-time digital signal processor, when it detects a EEG‐defined state of high corticospinal excitability (the trough of the ongoing sensorimotor μ‐oscillation). The stimulation intensity will be set to 80% of the resting (or active, see below) motor threshold in the first dorsal interosseus muscle of the paretic hand. A mean interburst interval of 3 s will be targeted by adjusting the power threshold of the μ‐oscillation in the EEG, leading to 20 min treatment duration.
