Low intensity focused ultrasound stimulation in stroke: A phase I safety & feasibility trial
Objective: We aimed to determine the maximum safe spatial-peak pulse-average intensity (ISPPA) of low-intensity focused ultrasound stimulation (LIFUS) in stroke patients and explore its effect on motor learning and corticospinal excitability.Methods: We adopted the classic 3 + 3 design to escalate ISPPA (estimated in-vivo transcranial value) from 0
