ROADFLEXION HP

Roadflexion walking foot is a highly dynamic foot for young and very active people, with a mobility level 3 (K-level). This is a new development of Roadwalking. The 3 laminate structure allows a foot’s response during all stance phases: in every moment at least 2 laminates work together to support the amputee user in his/her daily activities.
This prosthetic foot is composed of 3 main laminates: the inferior laminate defines the calcaneus and the forefoot; the posterior laminate defines the heel and has the function of cushioning; the superior laminates defines the instep and functions like an anterior tibialis muscle. A pyramid adapter closer to the ankle helps the pylon attachment. The inferior and posterior laminates start to work during Initial Contact: the durability and elasticity must allow load acceptance and storage with a shock absorption function to guarantee comfort to the user but at the same the balance and stability. Its function stops during the final phase of Toe-off when the forefoot gives the final propulsion. The posterior laminate works as a shock absorber during initial contact and stores energy that the laminate release after the mid-stance phase until toe-off during the propulsion phase; the superior laminates work like the anterior tibialis muscle permitting a gradual foot roll-over until forefoot contact to the ground; The Roadflexion foot has 60 % of efficiency (The ratio between the energy released and stored).
