Optimal number of active sites for TIME. TIME models with 12 and 20 ASs are represented in panel (a). Highlighted insets represent the fascicles selectively stimulated. The elicited voltage distributions are plotted in the planes orthogonal to the center of stimulating AS. Two sciatic nerve’s anatomies were used to create hybrid models for the estimation of electrode’s performance proximal and distal cross-section. b) A bar graph presents percentage recruitment of fascicles for TIME with varying number of active sites, from 12 up to 24. The increase from 16 to 20 ASs yields a significant augmentation in the number of selectively stimulated fascicles (* p < 0.001), while when passing from 20 to 24 ASs there was no statistical difference (p > 0.05), for both anatomies
