The bilateral loss of the grasp function associated with a complete lesion of the cervical spinal cord represents a severe handicap for social participation of the affected individuals. Any improvement of an impaired grasp function is highly desirable not only from the patients point of view but also for economic reasons. Motor neuroprostheses based on surface functional electrical stimulation (FES) provide a non-invasive option for generation of multiple grasp patterns. Closed-loop control of multi-pad FES electrodes allow for robust grasp pattern generation independent of wrist rotation.
EEG-based BCIs represent a valuable component of a neuroprosthetic user interface. A major advantage of BCIs is that they do not depend on residual motor functions. BCIs based on motor intention have enormous implications providing natural control of grasping neuroprostheses for individuals with a high spinal cord injury by relying on volitional signals recorded from the brain directly involved in upper extremity movements. This may also open up new avenues for using BCI-controlled neuroprosthesis as a tool in task-oriented, neurorestorative therapies. FES rehabilitation utilities similar technology as neuroprothesis but is only effective in patients that have some minimal residual movement and had recently been injured. It is aiming at restoration of sensory and motor pathways in both the brain and the spinal cord, thereby achieving restoration of motor functions.
This interdisciplinary workshop will give an update on the application of noninvasive BCI-controlled grasp neuroprostheses in end users and will include a combination of coordinated invited talks together with demonstrations and structured targeted discussions.
