Robotic devices are being increasingly used in motor rehabilitation programs, leading to very promising results and presenting some advantages over therapist-assisted training. Nevertheless, little is known regarding the kinetic patterns and electromyographic patterns exhibited by humans under the application of different robotic guidance forces. The main goal of this study was to evaluate the obtained joint mechanical performance and muscular response during robotic-aiding walking with modifications of the guidance force provided to healthy subjects. EMG and kinetic patterns were recorded in ten healthy subjects while they walked with body weight support and assisted by an exoskeleton. Different muscular activation patterns were obtained according to the demand. In general, subjects exerted lower forces on Lokomat with the decrease of guidance force and the increase of speed. This study gave us the basis to compare future biomechanical data of post-stroke patients during robotic-aided walking, in comparison with healthy subjects.
