Human movement analysis: The soft tissue artefact issue

This Special Issue of the Journal of Biomechanics reports an overview of the innovative research being conducted on a problem which every researcher reporting on the kinematics of humans and animals must cope with. The problem is rooted in our inability to directly observe the bones of our participants during the activities of interest and it represents a critical challenge since it is the motion of these underlying bones that is generally the nexus of our research.
