Summary: Using a case study, it is demonstrated that patients with weak plantar flexors need a dorsiflexion stop to restore a balanced gait. The forefoot lever is activated by limiting dorsiflexion with the aid of a defined dorsiflexion stop. At an orthosis without a defined dorsiflexion stop the forefoot lever remains inactive resulting in a prolonged stance phase and a delayed heel lift. By means of a video-supported gait analysis, it was established that a knee-ankle-foot orthosis (KAFO) with a defined dorsiflexion stop prevents an excessive dorsiflexion and enables a physiological heel lift. Thereby, the percentage of the stance phase can be reduced and the gait becomes more balanced.

Keywords: weak plantar flexors, orthoses, dorsiflexion stop, gait analysis, step symmetry
