Design and model a novel ankle foot orthosis

A lower limb orthosis is a type of external supporting devices that are used to support the patients who have problems due to trauma, incomplete spinal cord injury, stroke, etc. in the process of treatment and recovery. In the three articulations of lower extremity, ankle joint bears more weight than the other joints. Almost the current active, passive ankle orthosis systems focus on controlling dorsiflexion, plantar flexion around ankle joint or both of them. In reality, however, the locomotion of human is continuous movement of Center of Pressure (CoP) points underneath the foot. This paper suggests a novel ankle orthosis system based on CoP. This new model can control dorsiflexion, plantarflextion to prevent foot from foot slap and foot drop effect for patients who have trouble with their ankle. This paper will demonstrate the design and the model of the novel orthosis system.
