Abstract

This research project aims to develop an adaptive strategy based on variable impedance for walking rehabilitation of pos-stroke patients. The proposed strategy will be evaluated in two different robotic devices. The first device is the lower limb exoskeleton Exo-Kanguera, designed and built by the proposer in previous project. The device has three degrees of freedom, acting at hip, knee, ankle joints using series elastic actuators. The second device, named Anklebot, has active actuation in two ankle joints (dorsi/plantarflexion and inversion/eversion) by controlling the impedance of the interface between the device and the user. The proposed adaptive strategy considers the variation of the mechanical impedance of the robotic device's joint based on performance and participation of the patient during the therapy session. It will be proposed cost functions that seek to optimize the interaction between patient and robot, aiming a faster recovery. The performance and participation of patients will be evaluated by means of the data from motion and force, and myoelectric signals captured from the main muscles of walking. The evaluation of the proposed strategy will initially be held in volunteers. (AU)
