Development and validation of a robotic system for ankle joint testing

In vitro testing is widely used to assess the contribution of different soft tissues in joints kinematics. This is achieved by measuring the load –displacement relationship under load or displacement control. Typical load–displacement curves have low and high stiffness regions. In the low stiffness region, large displacements occur from small loading. Large loads occur with very small displacements in the high stiffness region. This impli es the need for high precision in measuring the loads and displacements for the low and high regions, respectively [1].
