Depending on the indication, a different effect of the leg orthosis is the goal of the fitting. In the case of partial or even complete paralysis of the leg muscles, for example, we want to achieve a supporting or stabilizing effect. This means that own impulses are stimulated by the orthosis fitting, and the affected leg is thus activated in the best possible way. As a result, a physiological gait pattern can be achieved, which would not be possible without a leg orthosis.
Furthermore, corrective thigh orthoses are frequently used, especially in pediatric and adolescent medicine. Malpositions of the leg caused by disease can be corrected by a leg orthosis. In addition, a suitable leg orthosis prevents secondary complaints such as back or shoulder pain. The reason for such complaints is often a relieving posture or an uneven gait pattern, which is corrected by a leg orthosis.
The design and the choice of the knee and ankle joint systems used are decisive for the implementation of the fitting objective.
