CUAFO (Custom Urethane Ankle Foot Orthosis) is a new concept in orthotics fabrication. It is used for compensation of insufficient muscle function of lower limb and correction of alignment of ankle and foot. The orthosis is made by wet lamination technique over a custom made plaster positive model. The matrix of the nylon brace is urethane which has not previously been used for manufacturing of orthoses. It has elastic, rubber-like features that make the orthosis very pleasant to wear.
