Ischemic Stroke, Acute Clinical Trial
Official title:
Brain-Oscillation-Synchronized Stimulation to Enhance Motor Recovery in Early Subacute Stroke
We will investigate the therapeutic efficacy of EEG-synchronized noninvasive repetitive transcranial magnetic stimulation (rTMS) in the early subacute phase after ischemic stroke to improve upper limb motor rehabilitation. We hypothesize that synchronization of rTMS with the phase of the ongoing sensorimotor oscillation indicating high corticospinal excitability leads to significantly stronger improvement of paretic upper limb motor function than the same rTMS protocol non-synchronized to the ongoing sensorimotor oscillation or sham stimulation.
High-frequency rTMS will be applied to the ipsilesional motor cortex in 400 bursts of 100 Hz triplets with a mean inter-burst interval of 3 s (20 min treatment duration, 1,200 pulses per day) for 5 consecutive workdays (6,000 pulses total) at a stimulus intensity of 80% of resting motor threshold, in one of three conditions/arms, followed by 40 min task-specific hand/arm-physiotherapy. ;
