Book Description
This book provides a comprehensive overview of the current state of the art of practical applications of neuroprosthesis based on functional electrical stimulation for restoration of motor functions lost by spinal cord injury and discusses the use of brain-computer interfaces for their control. The book covers numerous topics starting with basics about spinal cord injury, electrical stimulation, electrical brain signals and brain-computer interfaces. It continues with an overview of neuroprosthetic solutions for different purposes and non-invasive and invasive brain-computer interface implementations and presents clinical use cases and practical applications of BCIs. Finally, the authors give an outlook on cutting edge research with a high potential for clinical translation in the near future. All authors committed themselves to use easy-to-understand language and to avoid very specific information, focusing instead on the essential aspects. This makes this book an ideal choice not only for researchers and clinicians at all stages of their education interested in the topic of brain-computer interface-controlled neuroprostheses, but also for end users and their caregivers who want to inform themselves about the current technological possibilities to improve paralyzed motor functions.

Book Description
Stroke and spinal cord injury often result in paralysis with serious negative consequences to the independence and quality of life of those who sustain them. For these individuals, rehabilitation provides the means to regain lost function. Rehabilitation following neurological injuries has undergone revolutionary changes, enriched by neuroplasticity. Neuroplastic-based interventions enhance the efficacy and continue to guide the development of new rehabilitation strategies. This book presents three important technology-based rehabilitation interventions that follow the concepts of neuroplasticity. The book also discusses clinical results related to their efficacy. These interventions are: functional electrical stimulation therapy, which produces coordinated muscle contractions allowing people with paralysis to perform functional movements with rich sensory feedback; robot-assisted therapy, which uses robots to assist, resist, and guide movements with increased intensity while also reducing the physical burden on therapists; and brain–computer interfaces, which make it possible to verify the presence of motor-related brain activity during rehabilitation. Further, the book presents the combined use of these three technologies to illustrate some of the emerging approaches to the neurorehabilitation of voluntary movement. The authors share their practical experiences obtained during the development and clinical testing of functional electrical stimulation therapy controlled by a brain–computer interface as an intervention to restore reaching and grasping.

Book Description
This book showcases recent trends in brain-computer interface development. It highlights fascinating results in areas such as language decoding, spinal cord stimulation to enable gait and to restore hand functions. The contributions are based on the 12 nominated brain-computer interface projects of the BCI Award 2022. Every year an international jury selects the most innovate BCI projects and nominates 12 projects before selecting the 1st, 2nd and 3rd place winners. In the book, each project is described in detail by the team of scientists behind it, and the editors provide a concluding discussion of the highlights and overall progress in the field.

Book Description
Approximately 285,000 people are living with a Spinal Cord Injury (SCI) in the United States alone and there are about 17,500 additional cases each year. Over half of these SCI cases result in tetraplegia, which impairs quality of life and requires the need for self-care assistance. Individuals with tetraplegia identify restoration of hand function as a critical, unmet need to regain their independence and improve quality of life. Brain-Computer Interface (BCI)-controlled Functional Electrical Stimulation (FES) technology addresses this need by reconnecting the brain with paralyzed limbs to restore function. There are multiple groups working to develop BCIs for SCI applications and incredible progress has been accomplished. However, there is still a substantial amount of research and development required to optimize the technology in order for people with tetraplegia to integrate the neurorehabilitation devices into their daily lives. The work presented in this thesis aims to (I) translate BCI- FES technology from research devices to clinical neuroprosthetics, (II) enhance decoder performance through optimal selection of neurally separable hand functions, and (III) improve neurorehabilitation BCI-FES systems through integration of error-based feedback. Three studies were conducted with a tetraplegic participant using an intracortically-controlled, transcutaneous FES system designed for motor recovery to address each aim. We demonstrate that (I) our BCI-FES system can enable seven functional, skilled hand grasps that can generate adequate force to manipulate everyday objects with high-precision and naturalist speed, (II) stable representations of different hand movements can form in a very small area of the motor cortex and discriminability between these neural representations can affect decoder performance, and (III) information regarding mismatches between motor intention and muscle activation in a tetraplegic participant using a BCI-FES is expressed through single unit activity in the hand region of the motor cortex and is detectable with machine learning algorithms. This work improves upon the state-of-the-art for neurorehabilitation assistive devices and provides insight for developing methods to further optimize BCI performance.

Book Description
This dissertation seeks to develop novel neurorehabilitative therapies and neuroprostheses for restorative treatments in stroke and spinal cord injury (SCI) individuals. Since standard physiotherapies and substitutive solutions only provide a limited degree of restoration of the lost motor behavior in these individuals, novel brain-computer interfaces (BCI) have been sought. To develop BCI systems for stroke and SCI individuals, a high-performance electroencephalogram (EEG) based BCI system was developed and tested under several conditions. This system utilized data-driven decoding methodologies to obtain real-time control of several external devices. The external devices that were integrated and tested with this BCI system include a hand orthosis for stroke individuals with hand weakness, a noninvasive functional electrical stimulation (FES) system for the treatment of post-stroke foot drop, a virtual reality training environment to assess attempted or kinesthetic motor imagery of walking control strategies, a robotic gait orthosis mounted on a treadmill for ambulation training after SCI, and a noninvasive FES device for overground walking for those with paraplegia due to SCI. The BCI systems directed towards the treatment of stroke individuals focused on elementary motor behaviors common in chronic stroke individuals: foot drop and hand weakness (i.e. grasping and extension of the hand). On the other hand, the BCI systems for SCI individuals focused on ambulation after paraplegia. Finally, all systems were tested in both able-bodied individuals and those with stroke or SCI to assess the performance, safety, and applicability of these devices. All BCI systems allowed individuals to control the external devices purposefully in real time. Furthermore, the BCI driven neurorehabilitative therapies and neuroprostheses presented here allowed for stroke and SCI individuals to obtain real-time control of the desired motor behavior using intuitive control strategies after only minimal training, and individuals were able to maintain this high level of control after several days to months. This provides preliminary evidence that neurorehabilitative therapies and implantable neuroprostheses in stroke and SCI individuals are feasible. If future studies are successful, these systems may provide noninvasive training platforms for implantable neuroprostheses or noninvasive neurorehabilitative therapies for stroke and SCI individuals, thus becoming novel restorative treatments.
