Abstract

The development and a preliminary evaluation of a new active ankle-foot orthosis for gait assistance called T-FLEX are presented in this paper. The purpose of this device is to support patients with locomotion disabilities during rehabilitation treatment of the ankle joint. This device is based on bio-inspired actuation, in which the stiffness can be adjusted according to a gait phase detection, thereby reproducing the behavior of antagonistic muscles. A preliminary trial with a healthy subject (kinematic analysis) reveals an increase in the range of motion in ankle kinematics, which is desirable for ankle rehabilitation and assistance.
