Abstract

Active ankle foot orthosis is used as a supporting aid to restore the complex ankle foot movements of the subjects with neurological or muscular pathologies. This paper aims at designing an embedded control system for an active ankle foot orthosis, which can be used in the case of hemiparesis subjects as a rehabilitation aid. The designed orthosis can aid both dorsiflexion and plantar flexion movements. Fuzzy logic is used in the controller design by getting the real time gait data and implementing on National Instruments MyRIO hardware. Force sensors are used for gait analysis. Results obtained through various simulation and hardware modules shows that the rule base closely mimics the human gait pattern. The fuzzy controller output are tabulated which shows the force values and corresponding angular movement provided for the active AFO.
