Three-dimensional kinematic and kinetic analysis using photogrammetric techniques has been increasingly used in biomechanical studies of human movement (Allard, et al., 1995), as more complex morphology can be investigated than with simple 2D analyses. However, most 3D applications only focus on specific parts of the body, such as the lower limbs, where the structure of the multi-segment model is relatively simple, and the kinetic analysis is only conducted from distal to proximal segments sequentially. The SMAS methodology applies to general open-loop multi-segment systems, and makes best use of the available kinematic information. Moreover, unknown external forces and moments can be derived, as well as the internal joint forces and moments.
