FES position control of forearm using EOG

Abstract

In recent years, the number of individuals with disabled motor functions has increased. However, restoring motor functions is possible by providing electrical stimulation to the peripheral nerves. Flexible operation methods are desirable for .people with central nerve disorders as they can be used in daily life despite limited residual motor functions. Various examples using electromyogram (EMG), joint movement or breathing to control functional electrical stimulation (FES) have been reported. The present work investigates eye direction recognition experiments and the possibility of controlling the angle of the forearm using electrical stimulation. The target angle for the forearm is determined using electrooculogram (EOG) to allow more natural operation. In addition, PD controller and disturbance observer are applied to realize forearm movement and controlled stimulation. © 2009 Springer Berlin Heidelberg.
