Application of electrode matrix to locate stimulation sites for hand functions of SCI patients

Abstract

The main topic of this work is to investigate the applicability of electrode matrices for stimulating hand function. Of particular interest is the optimal positioning of electrodes that will elicit some lost hand functions in SCI patients with spinal cord injury at level C6-C7. For this purpose electrode matrices are used. They allow relocation of stimulating sites without moving the electrodes. Various forms are made from different combinations of electrodes in the matrix. Results show that the location of the stimulating site is quicker and the function more selective using electrode matrices with small electrodes. © 2009 Springer-Verlag.
