Unimpaired subjects' ROM. The mean values of the unimpaired subjects' (A) MCP, (B) PIP and (C) DIP joints for digits 2-5 under 3 conditions: passive stretch, active-unassisted movements inside HEXORR and active movement outside of the exoskeleton. For the first digit, the joints are the (A) CMC, (B) MCP and (C) IP. Twelve of the fifteen tested joints showed no significant ROM differences between active movements outside and inside HEXORR.
