Book excerpt: This book presents a new framework to improve the integration of exoskeletons in hemiparetic patients. The idea is to reduce potentially damaging compensatory strategies in the non-paretic leg, by ensuring a proper technology embodiment of the robotic exoskeletons in the nervous system. Upon reviewing control strategies for partial robotic exoskeletons applied to human gait, the book introduces robotic exoskeletons control algorithms, which were developed with the intention to promote gait symmetry by assisting the affected limb of hemiparetic patients according to the movement of the non-paretic leg. This new paradigm aimed at promoting the device's embodiment was expected to counteract the compensation mechanisms, which would become unnecessary and thus disappear. The control strategy relies on the gait phase estimation of the sound leg calculated using an adaptive frequency oscillator and was evaluated on post-stroke patients affected by hemiparetic gait, and the results are described in this book. All in all, this book offers a timely snapshot on control strategies for post-stroke robotic gait assistance. It also presents new findings concerning the role of robotic controllers in the embodiment of such devices, and their implications for new assistance paradigms for people with neurological gait disorders.

Book excerpt: The concepts represented in this textbook are explored for the first time in assistive and rehabilitation robotics, which is the combination of physical, cognitive, and social human-robot interaction to empower gait rehabilitation and assist human mobility. The aim is to consolidate the methodologies, modules, and technologies implemented in lower-limb exoskeletons, smart walkers, and social robots when human gait assistance and rehabilitation are the primary targets. This book presents the combination of emergent technologies in healthcare applications and robotics science, such as soft robotics, force control, novel sensing methods, brain-computer interfaces, serious games, automatic learning, and motion planning. From the clinical perspective, case studies are presented for testing and evaluating how those robots interact with humans, analyzing acceptance, perception, biomechanics factors, and physiological mechanisms of recovery during the robotic assistance or therapy. Interfacing Humans and Robots for Gait Assistance and Rehabilitation will enable undergraduate and graduate students of biomedical engineering, rehabilitation engineering, robotics, and health sciences to understand the clinical needs, technology, and science of human-robot interaction behind robotic devices for rehabilitation, and the evidence and implications related to the implementation of those devices in actual therapy and daily life applications.

Available in PDF, EPUB and Kindle. Book excerpt: This open access book focuses on practical clinical problems that are frequently encountered in stroke rehabilitation. Consequences of diseases, e.g. impairments and activity limitations, are addressed in rehabilitation with the overall goal to reduce disability and promote participation. Based on the available best external evidence, clinical pathways are described for stroke rehabilitation bridging the gap between clinical evidence and clinical decision-making. The clinical pathways answer the questions which rehabilitation treatment options are beneficial to overcome specific impairment constellations and activity limitations and are well acceptable to stroke survivors, as well as when and in which settings to provide rehabilitation over the course of recovery post stroke. Each chapter starts with a description of the clinical problem encountered. This is followed by a systematic, but concise review of the evidence (RCTs, systematic reviews and meta-analyses) that is relevant for clinical decision-making, and comments on assessment, therapy (training, technology, medication), and the use of technical aids as appropriate. Based on these summaries, clinical algorithms / pathways are provided and the main clinical-decision situations are portrayed. The book is invaluable for all neurorehabilitation team members, clinicians, nurses, and therapists in neurology, physical medicine and rehabilitation, and related fields. It is a World Federation for NeuroRehabilitation (WFNR) educational initiative, bridging the gap between the rapidly expanding clinical research in stroke rehabilitation and clinical practice across societies and continents. It can be used for both clinical decision-making for individuals and as well as clinical background knowledge for stroke rehabilitation service development initiatives.

Available in PDF, EPUB and Kindle. Book excerpt: Rehabilitation Robotics gives an introduction and overview of all areas of rehabilitation robotics, perfect for anyone new to the field. It also summarizes available robot technologies and their application to different pathologies for skilled researchers and clinicians. The editors have been involved in the development and application of robotic devices for neurorehabilitation for more than 15 years. This experience using several commercial devices for robotic rehabilitation has enabled them to develop the know-how and expertise necessary to guide those seeking comprehensive understanding of this topic. Each chapter is written by an expert in the respective field, pulling in perspectives from both engineers and clinicians to present a multi-disciplinary view. The book targets the implementation of efficient robot strategies to facilitate the re-acquisition of motor skills. This technology incorporates the outcomes of behavioral studies on motor learning and its neural correlates into the design, implementation and validation of robot agents that behave as ‘optimal’ trainers, efficiently exploiting the structure and plasticity of the human sensorimotor systems. In this context, human-robot interaction plays a paramount role, at both the physical and cognitive level, toward achieving a symbiotic interaction where the human body and the robot can benefit from each other’s dynamics. Provides a comprehensive review of recent developments in the area of rehabilitation robotics Includes information on both therapeutic and assistive robots Focuses on the state-of-the-art and representative advancements in the design, control, analysis, implementation and validation of rehabilitation robotic systems

This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Robotic rehabilitation for physical therapy has several advantages over conventional manual rehabilitation, especially in the aspects of accuracy and repeatability. Initial attempts at robotic rehabilitation focused on training muscles by moving limbs in a fixed repetitive pattern. Later it was realized that such an approach could be suboptimal. Better approach would be the use of 'assist-as-needed' paradigm, where an orthotic device provides just enough assistance to enable the patient to move his leg under his own control. However, at this time, lower extremity devices which can apply appropriate forces to implement this paradigm are still in research and not commercially available. The goal of this work is to develop lower extremity orthotic devices using assist-as-needed paradigm for robotic rehabilitation. To achieve this goal two orthotic devices were developed. They are Gravity Balancing leg Orthosis (GBO) and Active Leg EXoskeleton (ALEX). GBO assists persons with hemiparesis to walk by reducing or eliminating the effects of gravity on the affected limb. The amount of assistance provided can be tuned by the therapist from 0% to 100% gravity balancing. For a quantitative evaluation of the performance of the device several experiments were conducted. These experiments were performed on five healthy subjects and three stroke patients. The results showed that with the GBO set to 100% balancing the EMG activity from the rectus femoris and hamstring muscles was reduced by 75%, during static hip and knee flexion, respectively. For leg-raising tasks the average torque for static positioning reduced by 66.8% at hip joint and 47.3% at knee joint, however if transient portion of the leg raising task is included, the average torque at hip reduced by 61.3% and at knee increased by 2.7% at knee joints. In the walking experiment there was a positive impact on the range of movement at the hip and knee joints, especially for stroke patients, the range of movement increased by more than 57% at hip joint and by more than 73% at the knee joint. These results show that the GBO provides assistance which can be used for rehabilitation. An intensive training of a stroke patient was performed to study the long term effects of GBO, the training lasting for six weeks. The training started out with maximum assistance of 100% gravity balancing and gradually reduced to 0% by the end of training. Patient is also shown visual display of his gait pattern in real time and summary performance after individual sessions. Some of the effects of the training were, increase in patients preferred speed of treadmill walking from 2.72 km/h to 3.04 km/h, patient's preferred overground speed increased from 3.38 km/h to 3.86 km/h by the last evaluation. An improvement of gait pattern was seen where the patients gait pattern became more like a healthy subject's pattern. The patient was able to increase weight bearing on the hemiparetic leg and was more symmetric in his walk. ALEX, on the other hand, is a motorized orthotic device. To achieve the goal of 'assist-as-needed' paradigm for ALEX, Force-Field controller was developed. This controller generates "virtual walls'' in the plane containing human thigh and shank segments. These virtual walls guide and assist the subject's foot along the prescribed trajectory. Linear actuators were used at hip and knee joints of the device. To make the actuators back-drivable, friction compensation was used. Gait training studies with healthy subjects were conducted to measure the effectiveness of ALEX in retraining modified gait pattern. The results show that a healthy human leg muscles can be trained in about 45 to 60 minutes to a modified pattern of foot trajectory. A 15-day long gait training was conducted with a stroke patient using ALEX, the results indicate that using ALEX and force-field controller, the patient's gait pattern improved significantly in many aspects. His gait speed improved both on treadmill from 1.45 km/h to 2.57 km/h and overground from 1.82 km/h to 2.50 km/h. His foot trajectory increased and got about 85% closer to a healthy subject's foot trajectory. Knee flexion increased from 27.2 deg to 47.5 deg and ankle dorsi-flexion increased from 1.9 deg to 5.9 deg by the end of the training. All these results indicate that by using these devices suitably and implementing a long term gait training can help patients with walking disability in a speedy recovery.
