Adaptive Dorsiflexion and Plantar flexion in Active Ankle Foot Orthosis

Abstract: Impairments of Ankle foot is caused by spinal cord injuries, multiple sclerosis, cerebral palsy, and polio. Foot slap and foot drag during swing movement of leg are the problem faced during gait. To support such ankle foot impairments orthotic devices are used to achieve the proper gait movements. Currently there are Ankle Foot Orthosis (AFO) which provide assistance for gait which are majorly of passive type. Active AFO is current trend of research. There are many Active AFOs which are recently developed which provide fix dorsiflexion and plantar flexion movement. This paper propose methodology to achieve adaptive dorsiflexion and planter flexion movement of impaired ankle foot depending upon the healthy ankle foot movements.

Keywords: Adaptive Dorsiflexion, Planter flexion, Active Ankle Foot Orthosis, untethered.
