Main grasping features analyzed.

<p>Representative MCP angle in normalized units (bottom) and its time derivative (normalized angular velocity, top) profiles from subject S₉ in the T₁Z₁ condition. Solid black lines indicate the time of the impact event. Vertical dashed red lines indicate the onset of the grasping movement (TOnClose). Cyan dashed lines represent the time of peak hand closing velocity. TPvClose is the duration of the time interval between the occurrence of the peak of closing velocity and the IT. Green dashed lines represent the end of the hand closing movement (THClose). The hand closing time (CT) is the duration of the time interval between TOnclose and THClose. Horizontal dashed lines indicate the maximum and minimum of MCP angle and define the closing excursion or distance (CD).
