Abstract

Estimating the Knee Functional Axis (KFA) is crucial to both correctly implanting the prosthesis and accessing the joint kinematics. Researchers have mainly reported KFA by manual management of flexion extension movements, which are passively performed without any voluntary movements. Active touch and movement refers to what is ordinarily called as touching, which is defined as variations in skin stimulation caused by variations in a person’s motor activity.

The difference is very important for the individual. However, it has not been emphasized in the biomechanical literatures. This study aims to confirm the distinction between touching and being touched. We are particularly interested in measuring the Instantaneous Axes of the Knee (IAK) during locomotion. This geometrical “pattern” of the IAK is altered along with the touch pattern by the mechanical necessities of terrestrial movement.
