Typical result of feedback perturbation rejection control experiment with Subject S4. (a) Pull magnitude = 35%BW; flexion threshold = 0.70 where saturation pulse-width was not attained and (b) Pull magnitude = 45%BW; flexion threshold = 0.75 where saturation pulse-width was attained. The thick lines in the plots represent response means over 6 pull cycles ±1 standard deviation (thin lines). The trunk angles in the middle subplots were calculated using the marker positions captured with the Vicon cameras.
