title: An automatic hinge system for leg orthoses.
abstract: This paper describes a new automatic hinge system for leg orthoses, which provides knee stability in stance, and allows knee-flexion during swing. Indications for the hinge system are a paresis or paralysis of the quadriceps muscles. Instrumented gait analysis was performed in three patients, fitted with this new hinge system in a knee orthosis. The orthosis proves to satisfy the patients allowing them to walk without a knee-lock system.
