In Vivo Analysis of Trapeziometacarpal Joint Kinematics during Pinch Tasks
Figure 3
The distribution of the reference points at different pinching locations with three forces. The resting reference points are green, the points without force are red, the points with 50% maximum force are blue, and the points with 80% maximum force are black. The distribution of all subjects (left) and average trajectory of reference point movement (right) are shown above. The figures for when the MP joint, PIP joint, and DP are pinched are labeled (a), (b), and (c), respectively.
