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

Figure 1

(a) Visual cues presented to the subjects performing movements with different kinetic profiles (A1) and grasp types (A2), (b) grand average across trials and subjects for imaginary movements with different kinetic profiles in channel C3, (c) grand average across trials and subjects for executed movements with different kinetic profiles in channel C3, and (d) grand average across trials and subjects for different executed grasp types in channel C3. F20: fast (0.5 s) 20% MVC, F60: fast (0.5 s) 60% MVC, S20: slow (3 s) 20% MVC, and S60: slow (3 s) 60% MVC. Note the difference in amplitude on the -axis in (b). MVC: maximum voluntary contraction.
