Potential of robots as next-Generation Technology for clinical assessment of neurological disorders and upper-limb therapy
The Journal of Rehabilitation Research and Development, 2011Co-Authors: Stephen H. Scott, Sean P. DukelowAbstract:Robotic technologies have profoundly affected the identification of fundamental properties of brain function. This success is attributable to robots being able to control the position of or forces applied to limbs, and their inherent ability to easily, objectively, and reliably quantify sensorimotor behavior. Our general hypothesis is that these same attributes make robotic technologies ideal for clinically assessing sensory, motor, and cognitive impairments in stroke and other neurological disorders. Further, they provide opportunities for novel therapeutic strategies. The present opinionated review describes how robotic technologies combined with virtual/augmented reality systems can support a broad range of behavioral tasks to objectively quantify brain function. This information could potentially be used to provide more accurate diagnostic and prognostic information than is available from current clinical assessment techniques. The review also highlights the potential benefits of robots to provide upper-limb therapy. Although the capital cost of these technologies is substantial, it pales in comparison with the potential cost reductions to the overall healthcare system that improved assessment and therapeutic interventions offer.

potential of robots as next Generation Technology for clinical assessment of neurological disorders and upper limb therapy
Journal of Rehabilitation Research and Development, 2011Co-Authors: Stephen Scott, Sean P. DukelowAbstract:INTRODUCTION Over the last 100 years, radical changes have occurred in the assessment and treatment of disease. Blood tests now provide a wealth of information on the function of many organs, genetic testing can predict some diseases, and imaging techniques provide detailed quantitative information on the anatomical structure of the body. Substantial changes have also occurred in the treatment of disease. These include advances in pharmacological interventions and biomedical devices such as cardiac pacemakers, prosthetic limbs, and cochlear implants to ameliorate the effects of dysfunction. These advances reflect the transfer of knowledge and increased use of Technology from basic research to clinical practice. Not all fields of medicine have been equally influenced by Technology. With the exception of advances in structural and functional imaging, neurological assessment is still largely based on a clinician's perceptual decisions when monitoring the behavioral performance of the patient, such as testing the briskness of the muscle stretch reflex with a hammer tap or observing the range of motion and movement of a joint. This reliance on subjective assessment tools reflects the keen ability of the human perceptual system to observe even subtle differences between normal and abnormal behavior and the difficulty to develop technologies to replicate this ability of human observation. Although assessment tools have evolved to quantify sensory, motor, and cognitive deficits using clinician-based measurement systems, these approaches remain inherently subjective. Correspondingly, rehabilitation approaches for neurological disorders such as for stroke or traumatic brain injury remain largely based on one-on-one interactions between patient and therapist. Rehabilitation approaches vary widely across practitioners with little evidence to support why one approach is better than another [1-3]. The result is a vicious circle between neurological assessment and neurorehabilitation: the lack of sensitive tools to quantify dysfunction makes demonstrating the effectiveness of novel therapeutic approaches difficult, and limited improvement by existing treatments as measured by current assessments implies no need for better assessment tools. Our purpose with this review is to suggest that the time may be right for a profound change in neurological assessment and neurorehabilitation, particularly related to stroke and traumatic brain injury. Our hypothesis is that robotic technologies can provide a radically new and effective approach to clinical assessment of brain function and rehabilitation. This approach also takes advantage of advances in our understanding of brain function to develop a range of behavioral tasks to assess the various brain circuits that support sensory, motor, and cognitive function. As well, it highlights how these same technologies can be used for rehabilitation in subjects following stroke. Over the last 40 years, our understanding of how the brain supports sensory, motor, and cognitive function has substantially increased [4-5]. Behavioral studies on humans have identified how we use sensory input to the brain to perceive the world around us, make decisions, and guide our highly skilled and flexible motor actions. Anatomical tracing techniques highlight the anatomical connectivity among different brain regions. Neurophysiological studies in awake, behaving animals have uncovered how neural activity in various brain regions correlates with various sensory, motor, and cognitive functions. In turn, clinical research on various patient groups have highlighted how damage in even small portions of the brain can have a profound impact on brain processing. The culmination of these studies forms several basic principles about brain function. First, sensory and motor systems work together to permit us to move and interact in the environment and create our perception of the world. …

power situation and renewable energy potentials in nigeria a case for integrated multi Generation Technology
Renewable Energy, 2021Co-Authors: K Owebor, E O Diemuodeke, T A Briggs, M ImranAbstract:Abstract Globally, demand for electricity has seen a steady increase, with nations striving to meet the demand. However, Nigeria is abysmally struggling to meet the increasing demand with the meagre per capita electricity consumption of 151 kWh, which is lower than the average of per capita electricity in Africa. Presently, the grid-tied electricity installed capacity in Nigeria, estimated at 13,435 MW is primarily generated by fossil and hydro-power plants at approximate distribution of 82.3% and 17.7%, respectively. This work presents single capsule that shows a holistic narrative of the energy access sector in view of energy penetration, sustainability, Technology advancement and energy policy evolution. From available records, renewable energy sources in Nigeria are equitably distributed throughout the country, unlike the fossil reserves that are mostly concentrated in the south-south geopolitical zone. Also, there are huge potentials buried within untapped renewable energy in the country, namely wind, small-scale hydropower, geothermal, tidal and biomass energy. Furthermore, cutting edge power Generation technologies that incorporate fuel cell, gas-, steam-, and low grade-turbine with carbon capture and fired by dual fuel of natural gas and biomass is promising for both energy access and climate action. The Federal Government of Nigeria's friendly energy policies, coupled with political will to excite implementation are panacea to significantly drive energy access for sustainable socio-economic development.
