Effect of body position and external ankle load on the pendulum test in adults

The Wartenberg pendulum test has been commonly used to evaluate the passive stiffness of the knee in healthy and clinical populations. A joint is considered stiff if there is reduced passive motion. This reduction in passive motion occurs when intrinsic mechanical properties of the tissue about the joint resist deformation [1]. Passive stiffness for the pendulum test is often measured through kinematic variables including the number of leg swings, a relaxation index, and damping and stiffness coefficients, as among others.
