Book excerpt: Here I present several approaches to applying engineering design principles to the central nervous system with the goal of using closed-loop approaches to enhance rehabilitative processes. These approaches cover invasive access to the brain and spinal cord, as well as physical rehabilitation techniques that employ closed loop principles for direct clinical utility. Targeted plasticity in the motor cortex was induced in a nonhuman primate model using paired electrical stimulation. This stimulation produced robust changes in a subset of tested sites and conformed to the predicted changes following Hebb’s framework of spike-timing dependent plasticity. Novel electrode access to the cervical spinal cord allows for targeting of hand and arm motor pools. I designed, fabricated, tested, and iterated on two approaches to access the ventral aspect of the spinal cord to directly stimulate arm movement using targeted electrical stimulation with the goal of creating robust, de-fatiguing motor outputs from a stable stimulation site. Finally, I architected a closed-loop rehabilitation platform that directly measures hand and arm function, uses those measurements to control engaging gameplay in a digital environment, and quantify the quality of movement created by the user with the goal of making long term rehabilitation fun, accurate, and engaging for the end user. These approaches taken together represent a comprehensive approach to closed-loop motor rehabilitation.

Book excerpt: Millions of people worldwide are affected by neurological disorders which disrupt the connections within the brain and between brain and body causing impairments of primary functions and paralysis. Such a number is likely to increase in the next years and current assistive technology is yet limited. A possible response to such disabilities, offered by the neuroscience community, is given by Brain-Machine Interfaces (BMIs) and neuroprostheses. The latter field of research is highly multidisciplinary, since it involves very different and disperse scientific communities, making it fundamental to create connections and to join research efforts. Indeed, the design and development of neuroprosthetic devices span/involve different research topics such as: interfacing of neural systems at different levels of architectural complexity (from in vitro neuronal ensembles to human brain), bio-artificial interfaces for stimulation (e.g. micro-stimulation, DBS: Deep Brain Stimulation) and recording (e.g. EMG: Electromyography, EEG: Electroencephalography, LFP: Local Field Potential), innovative signal processing tools for coding and decoding of neural activity, biomimetic artificial Spiking Neural Networks (SNN) and neural network modeling. In order to develop functional communication with the nervous system and to create a new generation of neuroprostheses, the study of closed-loop systems is mandatory. It has been widely recognized that closed-loop neuroprosthetic systems achieve more favorable outcomes for users then equivalent open-loop devices. Improvements in task performance, usability, and embodiment have all been reported in systems utilizing some form of feedback. The bi-directional communication between living neurons and artificial devices is the main final goal of those studies. However, closed-loop systems are still uncommon in the literature, mostly due to requirement of multidisciplinary effort. Therefore, through eBook on closed-loop systems for next-generation neuroprostheses, we encourage an active discussion among neurobiologists, electrophysiologists, bioengineers, computational neuroscientists and neuromorphic engineers. This eBook aims to facilitate this process by ordering the 25 contributions of this research in which we highlighted in three different parts: (A) Optimization of different blocks composing the closed-loop system, (B) Systems for neuromodulation based on DBS, EMG and SNN and (C) Closed-loop BMIs for rehabilitation.

Book Synopsis New approaches for central nervous system rehabilitation by : Pawel Kiper

Download or read book New approaches for central nervous system rehabilitation written by Pawel Kiper. This book was released on 2024-02-09. Available in PDF, EPUB and Kindle. Book excerpt: Neurorehabilitation is a complex and growing field of motor rehabilitation. It is specifically directed to apply restorative techniques to stimulate neural plasticity of the central nervous system (CNS). Considering that neuroplasticity is maintained for the whole human life and can be stimulated through specific learning or exposure to enriched environments, we can hypothesize that applying specific treatments can be beneficial for people with CNS injury. Because the plateau of neuroplasticity can be observed after about 12 weeks from stroke onset it is vital to capitalize on this high level of brain reorganization by providing well-timed and well-designed treatments. Here we can distinguish a wide range of approaches developed for CNS recovery in acute, subacute, or chronic stage of injury. These approaches comprise priming or augmentation techniques, including innovative technologies like end-effector robots, exoskeletons, or virtual reality. Many of them have been confirmed as effective, but so far in clinical practice, we can still experience a lack of specific indications i.e., which therapy for how long time and for which patient’s impairment can be applied.

Download or read book Converging Clinical and Engineering Research on Neurorehabilitation written by José L Pons. This book was released on 2013-02-19. Available in PDF, EPUB and Kindle. Book excerpt: Restoring human motor and cognitive function has been a fascinating research area during the last century. Interfacing the human nervous system with electro-mechanical rehabilitation machines is facing its crucial passage from research to clinical practice, enhancing the potentiality of therapists, clinicians and researchers to rehabilitate, diagnose and generate knowledge. The 2012 International Conference on Neurorehabilitation (ICNR2012) brings together researchers and students from the fields of Clinical Rehabilitation, Applied Neurophysiology and Biomedical Engineering, covering a wide range of research topics: · Clinical Impact of Technology · Brain-Computer Interface in Rehabilitation · Neuromotor & Neurosensory modeling and processing · Biomechanics in Rehabilitation · Neural Prostheses in Rehabilitation · Neuro-Robotics in Rehabilitation · Neuromodulation This Proceedings book includes general contributions (2-page extended abstracts) from oral and poster sessions, as well as from special sessions. A section is also dedicated to pre-post conference workshops, including invited contributions from internationally recognized researchers. A selection of most relevant papers have been considered for publication in international journals (e.g. JNER, JACCES, ...)., therefore they will appear soon in their extended versions in Special Issues. These Proceedings also contain brief descriptions of keynote lectures from invited world-class professors, and a number of thematic round tables covering technological and institutional issues.
