Summary: Plantar flexors that are too weak or prolonged are responsible for the forefoot lever remaining inactive. An active forefoot lever generates a stable balance. It ensures the required safety when standing and causes the heel to lift from the ground at the right moment when walking. Thus, it is crucial for a balanced step length. If the plantar flexors are inactive, the forefoot lever is activated by a dorsiflexion stop. Therefore, AFOs and KAFOs should always be produced with ankle joints that have an adjustable dorsiflexion stop. The constructive difference lies between a static and a dynamic dorsiflexion stop. The correct position of the dorsiflexion stop is checked on the workbench and on the patient by means of various tests.
Keywords: biomechanics, weak plantar flexors, pathological gait, orthoses, dorsiflexion stop
