We have developed a new Ankle foot orthosis of light weight, and control of the plantar flexion and the dorsiflexion. The orthosis has two C-shaped springs on the side and a solid damper on the back. We designed a C-Shape spring and solid damper with considering their mechanical properties and ranges of motion (ROM) of ankle. C-shape spring automatically fit to many user's because it does not have a fixed axis. We experimented and evaluated the prototype by EMG and ankle ROM. Ankle of motion and pretibial muscle of EMG decreased at initial contact, but they increase at other.
