Index finger muscle-tendon locations, expressed in OpenSim frame (mm).

<p>The coordinate system of the OpenSim model is attached to metacarpal (secondmc), proximal (proxph2), middle (midph2) and distal (distph2) phalanges. x, y and z components indicate radioulnar (+ points out, perpendicular to the palm plan), axial (+ points from distal to proximal side) and dorsolar (+ points up, from palm to hand side), respectively. Optimized muscle-tendon locations of OpenSim are compared with those of experimental measurements (numbers in parentheses). ΔR is the Euclidean distance between OpenSim model and experimentally measured attachment sites [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0121712#pone.0121712.ref005" target="_blank">5</a>].</p><p>Index finger muscle-tendon locations, expressed in OpenSim frame (mm).
