delivered dynamic support, which preserved pelvic kinematics along vertical and
antero- posterior axes, which were consistent with reduced ground reaction forces. The
preliminary experiment in control implementation showed that the electrical and
software architecture provided a stable platform for controlling the actuation
mechanisms.
