Joint-pair coordination plots for an unimpaired subject. Plots display the 1st digit (A) CMC-MCP pair (B) MCP-IP pair and 3rd digit (C) MCP-PIP pair and (D) PIP-DIP pair (mean ± standard error). Paired t-tests indicate no significant differences between trajectories performed inside and outside of the exoskeleton. All joint angles are measured relative to the initial fully flexed posture of the hand.
