Classification of Hand Grasp Kinetics and Types Using Movement-Related Cortical Potentials and EEG Rhythms

Table 2

Classification accuracies obtained for different motor execution kinetic profiles. F20: fast 20% MVC, F60: fast 60% MVC, S20: slow 20% MVC, and S60: slow 60% MVC. SFS: sequential forward selection, and PCA: principal component analysis. The classification accuracies obtained without and with SFS and PCA are presented in the top and bottom part, respectively.
