Fig. 3From: Passive, yet not inactive: robotic exoskeleton walking increases cortical activation dependent on taskfNIRS results. Panels a (oxyHb results) and b (deoxyHb results) indicate the mean concentration (y axis) for each significant channel (x axis) after the first step of analysis. Error bars indicate standard error. Stars indicate significant differences between passive and active conditions after the second step of analysis. Panel c indicates the source/detector optode configuration with significant channels after the first step of analysis in black. Red oval indicates significant difference between passive and active conditions after the second step of analysis for oxyHb. Blue oval indicates significant difference between passive and active conditions after the second step of analysis for deoxyHbBack to article page
