Figure 4From: A pilot study of sensory feedback by transcutaneous electrical nerve stimulation to improve manipulation deficit caused by severe sensory loss after strokeConceptual diagram of sensory feedback by transcutaneous electrical nerve stimulation (SENS). a) Schematic overview of SENS. b) Upper panel is an example of the temporal profile of the output voltage. Lower panel represents the cutaneous stimulation sequence modulated in real time according to the output voltage shown in the upper panel.Back to article page
