These new designs of AFO can be rigid, semi-rigid, or dynamic. They must be customised with a full mould of the foot and ankle taken before the device is made and prescribed. As the device has more technical areas to take into consideration than a traditional foot orthotic, it requires closer follow-up monitoring. The base of the AFO incorporates a full custom foot orthotic, which then extends up the leg. It is designed to take into consideration a patient’s static and dynamic biomechanics, while being easy and comfortable to wear due to its lightweight, low-profile design.
