Figure 1
Sensor placement and experimental setup. (A) Diagram of the 17 sensors and their location on the suit. (B) A close-up view of the sensors on the shoulders, trunk and hip. (C) The orientation of the axes on the sensor. Using the right-hand Cartesian coordinate system, the y-axis line is aligned along the length of the inertial sensor while the x-axis is aligned along the width of the sensor. (D) Spatial schematic of the RAM task. (E) Spatial schematic of the “counting money” task.
Figure 2
RAM performance comparison between controls and ET. (A) Mean duration of pronation–supination cycles±SE. (B) Mean angular velocity of pronation–supination cycles±SE (left); maximal angular velocity of pronation–supination cycles±SE (center); maximal instantaneous angular velocity over the pronation–supination task±SE (right). (C) Mean angular displacement of pronation–supination cycles±SE for control participants (white) and participants with ET (black). The stars indicate a significant difference.
