Fig. 4From: Shoulder kinematics plus contextual target information enable control of multiple distal joints of a simulated prosthetic arm and handResults on performance metrics. Each grey line corresponds to a subject. Boxes show first and third quartiles, whiskers show min and max values. Left: approach time, lower is better. Center: approach speed, higher is better. Right: shoulder spread volume, lower is better. Blue: hybrid control with network C+; purple: hybrid control with network C−; red: natural control (N). Significant differences are indicated with stars: **\(\hbox {p} < 0.01\); ***\(\hbox {p} < 0.001\)Back to article page
