Participants will receive non-invasive electrotactile stimulation through electrodes attached to the skin of the upper limb, such as the fingertip, palm, elbow, or shoulder, depending on the stimulation condition. The study will assess discrimination thresholds for changes in stimulation frequency, stimulation amplitude, and temporal gaps in stimulation, together with task accuracy and reaction time.

This study is designed to test proprioceptive error compensation techniques in stroke patients.\n\nThe human nervous system often receives mismatched information from vision and proprioception during upper limb control, resulting in conflicting sensory inputs that limit the effectiveness of motor learning. In other words, real-time sensory feedback - a critical component of motor learning in the nervous system - is not reliably delivered. Therefore, this study seeks to resolve sensory conflicts by providing additional sensory information through electrical stimulation, with the goal of dramatically improving the effectiveness of motor learning.",[63,35],"Ischemic Stroke","RECRUITING","2026-06-10",{"date":67,"type":43},"2026-06-12",{"date":69,"type":23},"2026-09-01",{"date":71,"type":23},"2027-03-30",{"name":49,"class":50},1,""]
