Intramuscular EMGs were recorded from FDP, FDS, EDC, EDM, EIP, EPL, APL, FPL and FDI. Surface EMGs were recorded from TE (consisting of the intrinsic thumb muscles APB, FPB and OPP) and HTE (consisting of the intrinsic pinky finger muscles ADM, FDM and ODM). Needle electrode placements were verified using low current electrical stimulation. Subjects formed and held the instructed postures for 8 s, but only the steady state portion from t = 2.5 s to t = 5 s was analyzed (highlighted in gray).
