Abstract
An ankle foot orthosis having a lower leg element, a foot element being pivotably coupled to the lower leg element around a pivot axis, and a first energy storing unit being adapted such that moving the foot element relative to the lower leg element in dorsiflexion direction from a position in which the amount of energy stored in the first energy storing unit is minimal loads the first energy storing unit with energy. The first energy storing unit is adapted such that the amount of energy stored in the first energy storing unit is increased by moving the foot element relative to the lower leg element in a plantar flexion direction from a first position in which the amount of energy stored in the first energy storing unit is minimal into a second position and moving the foot element relative to the lower leg element in dorsiflexion direction from the second position back into the first position.
