Summary: Orthoses contribute greatly to the gait rehabilitation of patients with neurological disorders. The negative cast is the basis for the alignment of the orthosis and a successful orthotic treatment. The load on the leg during the making the negative cast determines the biomechanical properties of the finished orthosis. A dynamic pressure distribution measurement was performed at a patient who is suffering from hemiplegia after a stroke. Two different ankle-foot orthoses (AFOs) were tested during walking. The results show that the gait is significantly more balanced during walking when the cast of the AFO has been produced in a gait-related normal posture as opposed to a stance-related normal posture. Accordingly, the gait-related normal posture is well suited to produce orthoses for actively walking patients, whereas the stance-related normal posture is aimed at patients with an increased need for safety.
