Figure 1From: Effects of robotic guidance on the coordination of locomotionDependence of muscular activation on the level of robotic GF and walking speed for each investigated muscle. Left panel: group average activation is represented for treadmill and robotic walking (free walking on a treadmill and walking with four levels of GF in the robot-aided condition) against speed. Right panel: the integral of the average EMG envelopes are represented in a contour plot with 20 levels; interpolation was done to represent walking speed with respect to the treadmill (unassisted) and robotic walking (four levels of GF) conditions.Back to article page
