Electroacupuncture improves upper-limb motor function and modulates sensorimotor network connectivity in subacute stroke: a randomized controlled trial

Objective Electroacupuncture (EA) has been shown to facilitate post-stroke motor recovery; however, the underlying neurophysiological mechanisms remain insufficiently understood. This study aimed to investigate how EA modulates sensorimotor network (SMN) connectivity and to explore its relationship with upper-limb motor recovery in patients with subacute stroke. Methods Fifty patients with subacute stroke were randomly assigned to the EA group or sham EA (SEA) group. All participants received 18
