The "adV PowerSpring®" spiral orthosis made from the lightweight and flexible material carbon is developed, designed and manufactured for individual requirements in the workshops of adViva orthopaedic technology mechanics and gait analysis specialists. The production of the orthosis illustrates the complex requirements that adViva places on the subject of "dynamic movement". The spiral orthosis uses muscles, tendons and muscle fibers in the same way as "normal" walking. It supports natural movement and helps patients to achieve the goals they have set themselves faster and better.
