Résumé :

While great progress has been made in understanding the complex kinematic motion of articulating human joints using techniques such as motion capture, less is understood about contact mechanics within the joints. Pressure sensitive film can be used to record joint stresses under static loading conditions, and there are methods to measure cartilage-on-cartilage contact through activities of daily living (ADLs) using open MRI and dual X-ray spectroscopy. While these methods provide some insight into understanding joint contact mechanics, they do not provide direct measurement of the contact mechanics. However, Tekscan sensors permit direct measurement of interfacial contact area and stress, and they are being used for a variety of robotic, automotive, ergonomic, and biomedical applications. In particular, Tekscan sensors can be used to measure changes in joint contact mechanics in healthy, pathologic, and artificial joints under quasi-static and dynamic loading conditions. Therefore, this chapter explains how to perform Tekscan testing, as well as how to analyze, present, and interpret results.
