Biomechanical Analysis of Force Distribution in Human Finger Extensor Mechanisms

Figure 2

The movement constraint applied to each node in the tendon network. Each node is constrained to move along the line between the node itself (𝑃₀) and one vertex (𝑃_𝑉) of the bone facet containing the node to a new position (𝑃₁). The vertex chosen is the one which leads to the direction of node movement being closest to the direction of the tendon force.
