On the use of Non-Invasive Brain-Computer Interface Technology in Neurorehabilitation

Abstract

The prosthesis alignment is of central importance for a harmonic gait, especially for upper limb amputees. Today alignment optimization is based on static measuring and the experience of the orthopaedic technician. To objec- tify the alignment process a mobile gait analysis system based on 10 inertial sensors and a 6 DOF force and moment sensor was developed at the TU Berlin. The dedicated soft- ware adds dynamic gait parameters into the optimization process and guides the necessary changes in the prosthesis alignment. Therefore 19 common alignment changes were analysed based on measurements with 2 subjects fitted with the C-Leg knee. The anterior and posterior displacement of the knee will be the focus of an additional study with 6 subjects. Keywords:
