Restoration of grasping has the highest priority for people with cervical spinal cord injury (SCI). This chapter describes the non-invasive brain–computer interface (BCI)-controlled grasp neuroprosthesis developed within the European Horizon 2020 project MoreGrasp. Based on former projects of the collaborators, several innovative technologies were developed within the MoreGrasp project with the aim to achieve an intuitive thought-controlled restoration of hand function in end users with tetraplegia for supporting activities of daily living. The end users in the focus of this project have been people with sufficiently preserved elbow and shoulder movements, but missing hand and finger functions. In particular, within MoreGrasp a novel, closed-loop upper limb grasp neuroprosthesis was developed which could be controlled by different multimodal control options, namely user-friendly BCIs based on gel-less electrodes and wireless electroencephalogram (EEG) amplifiers using natural movement attempt strategies, a shoulder joystick and instrumented objects. All these control modalities could be tailored to the end users’ needs and capabilities. Furthermore, a web-based service infrastructure for registration, assessment, and training of end users was developed. It assisted experimenters as well as end users in prototype assessment and operation. Finally, a clinical study involving end users with tetraplegia evaluating the MoreGrasp technology at their homes was initiated. The first results obtained and the lessons learned are provided at the end of the chapter.
