Figure 5.
Learning curves of digit center of pressure and forces: pregrip and postgrip type switch (long-term adaptation). From top to bottom, data shown are the dy, the dLF, and the FGF, respectively. For 3d, the center of pressure and forces exerted on the finger side of the device result from forces exerted by the index and middle fingers. Data on the left and right column are from the LCM and RCM, respectively. Each plot shows data from two-digit grip trials followed by three-digit grip trials (squares) and trials performed in the reverse order (circles). Data are averages of all subjects (±SE).
