Depending on the indication, the goal of the fitting can be a different effect of the leg orthosis. In the case of partial or even complete paralysis of the leg muscles, for example, we want to achieve a supporting or stabilising effect. This means that the orthosis stimulates the patient’s own impulses and thus activates the affected leg in the best possible way. This makes it possible to achieve a physiological gait pattern, which would not be possible without a leg orthosis.
Furthermore, corrective thigh orthoses are often used, especially in paediatrics and adolescent medicine. A leg orthosis can be used to correct malpositions of the leg caused by disease. 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 can be remedied 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 goal.
