Abstract

Systems and methods for controlling an orthopedic joint device of a lower extremity, the orthopedic joint device comprising an upper part, a lower part mounted in articulated fashion to the upper part, and a conversion device arranged between the upper and lower parts. The conversion device provides for, during pivoting of the upper part relative to the lower part, mechanical work from a relative movement between the upper and lower parts to be converted and stored in at least one energy store and supplied back to the joint device with a time offset in order to assist the relative movement. The stored energy is converted back and the supply of mechanical work takes place in a controlled manner during the assistance of the relative movement.
