Optimisation of a combined ARGO-FES system: adaptation of the knee mechanism to allow flexion of the knee during the swing phase

Abstract: 1 2 ABSTRACT:The knee mechanism of an Advanced Reciprocating Gait Orthosis is adapted to allow flexion of the knee during the swing phase. The new knee mechanism is electrically controlled and consist!? of a mini DC motor with gearbox, a cam and a follower. Preliminary tests with the system are positive, but they show that it should not be used without FES.

“…These cables could be completely omitted by the construction of an electronic unlocking mechanism at the knee joint. 12 The substantial e ort necessary for rising could be diminished to a reasonable level by combining the ARGO with FES, as stimulation of the quadriceps assists in extending the knees.…”

“…We are currently involved in the development of such a hybrid ARGO-FES system. 12,13 Such further technological developments should take into account the experience obtained with the previously used systems. Therefore, investigation of the functional outcome of ARGO use, in patients ®tted for more than 1 year, was taken as the objective for the present study.…”
