Book Description
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.

Book Description
Stroke is the second highest cause of death worldwide and the third leading cause of adult disability across all age brackets. Recovering gait following stroke is a major goal of patients, and hence rehabilitation, as it is central to many activities of daily living. Of the different treatment modalities, robotic assisted gait training is growing in popularity, but is still considered complementary to, and not substitute for conventional therapies comprising physiotherapy, overground walking and body weight supported treadmill training. The potential advantages that lower limb robotics bring to neurorehabilitation over conventional therapies include, higher dosage, specificity, improved consistency, and duration, though these benefits have been slow to manifest. Exoskeletons are well placed to provide these benefits, as well as environmental variation and task salience if they can be used away from outpatient settings. Control strategies that may be enhancing of recovery are often confined to stationary exoskeletons, and the control of mobile exoskeletons is only loosely related to gait, if at all, which limits rehabilitation outcomes. -- The primary aim of this PhD thesis was to develop an adaptive, user-initiated gait Controller that aims to target a novel neural recovery pathway. The Controller would use a robotic exoskeleton, with the intention of developing novel neuroplasticity that is beneficial for gait and would be permissive of simultaneous control of hip and knee posture. A theoretical framework based on the principles of neuroplasticity was proposed that seeks to bring higher engagement, task variance, and volition to gait rehabilitation. This framework considers stroke and rehabilitation timelines and the interaction of the proposal with existing theory, how beneficial neuroplasticity may manifest, and how the proposal may be detrimental. A comprehensive survey of candidate lower limb devices followed (164 devices), to understand exactly what features are compatible, complementary, or contradictory to the proposed control method, and to understand the implications the various specifications have. Specifically, it was found that ambulating exoskeletons that can move around the environment were preferred for their ability to be used in the community and the home, and that extended joint range of motion will be permissive of activities that are supportive of gait such as sit-to-stand and stair ascent/descent. Of the various control systems that have been implemented with exoskeleton devices, trajectory control, where motion is enforced on the limb by the exoskeleton, is preferred. -- The method of control was assessed for suitability as a gait controller through a participant study (n = 21). Participants were asked to reproduce the motion required for the controller, and with minor modification to participant motion it was shown that reliable control signals can be obtained. The remainder of the thesis applies the learnings of the previous stages in the development of the Controller and an accompanying Sensor. The custom Sensor was designed with a small form factor to be applied on the Controller. The thesis concludes with an implementation of the Controller and a successful demonstration of the proposed concept, where the control signals are reproduced on a scale lower limb exoskeleton. The full technical detail and specification of the Controller, and the custom position Sensor developed specific for this application, are presented as part of this work. -- This work has added a new theoretical framework for gait control following stroke and has added technological capability to implement the proposal. It is the primary recommendation of this PhD that the novel control method be tested further with participant studies and that the component hardware be developed further. Therapies targeting novel recovery mechanisms breathe fresh air into rehabilitation and may inspire other new treatments, and future funded work originating from this PhD will see the concept tested with a chronic stroke population, using an ambulating exoskeleton and the Controller.

Book Description
The mobility of the lower extremities may be affected by neurological conditions such as stroke or spinal cord injury. When, motor function, gait coordination and muscle strength are impaired. Rehabilitation can improve the autonomy of legs movement in order to carry out everyday tasks such as walking or stand up, also known as a Sit-To-stand. Sit-To-Stand is a task that requires considerable effort for those who have suffered a stroke or other type of injury. To perform the Sit-To-stand movement there are variables such as force, velocities, position angles, among others that can be modeled with the use of robotic exoskeletons. This project develops a Sit-To-Stand control strategy implemented in a robotic exoskeleton. This is based on previous work on the development of control strategies for the rehabilitation of the Sit-ToStand. Where Sit-To-Stand transition phases combined with position and admittance control strategies are used. The objectives of this project are to find optimal values of the angles of the joints involved in the transition of the phases and to propose an improvement in the control strategy to assist people with lower extremities movements.

Book Description
The new technological advances opened widely the application field of robots. Robots are moving from the classical application scenario with structured industrial environments and tedious repetitive tasks to new application environments that require more interaction with the humans. It is in this context that the concept of Wearable Robots (WRs) has emerged. One of the most exciting and challenging aspects in the design of biomechatronics wearable robots is that the human takes a place in the design, this fact imposes several restrictions and requirements in the design of this sort of devices. The key distinctive aspect in wearable robots is their intrinsic dual cognitive and physical interaction with humans. The key role of a robot in a physical human–robot interaction (pHRI) is the generation of supplementary forces to empower and overcome human physical limits. The crucial role of a cognitive human–robot interaction (cHRI) is to make the human aware of the possibilities of the robot while allowing them to maintain control of the robot at all times. This book gives a general overview of the robotics exoskeletons and introduces the reader to this robotic field. Moreover, it describes the development of an upper limb exoskeleton for tremor suppression in order to illustrate the influence of a specific application in the designs decisions.

Book Description
Stroke is the leading cause of neurological disability in the US and stroke patients typically require an extensive rehabilitation therapy to regain some of their lost neuromuscular functionality. Various robotic devices have been developed for post-stoke rehabilitation to reduce the labor intensity of therapists and rehabilitation cost and provide therapists with quantitative information about rehabilitation procedure and patients recovery. The robot-patient interaction plays an important role in effectiveness of robotic therapy. Different strategies have therefore been proposed and employed to control rehabilitation robots in order to improve the therapy outcome. However, since the underlying neural mechanisms of motor recovery after stroke are not completely understood, and the effect of each stroke is unique and can be very different from that of other strokes, it is not clear what control strategy is the best. Adaptive assist-as-needed (AAN) control is a movement training methodology with very desirable characteristics for rehabilitation robotic applications. It can adaptively modulate the level of robotic assistance to promote patient active involvement in therapy. In this research, the evolution of two robotic devices for stroke rehabilitation is presented. The FINGER (Finger Individuating Grasp Exercise Robot) rehabilitation robot was designed to assist with hand and finger rehabilitation. A discrete performance-based adaptive control was implementer on FINGER that could provide patients with a suitable assistance level in order to modulate success during therapy game play. In a separate experiment, an inertial and directionally dependent AAN controller was implemented and tested on the FINGER robot. Additionally, the design and development of a 4-DOF parallel robot for upper extremity impairment rehabilitation is presented. This end-effector type rehabilitation robot has low end-effector inertia, is very backdrivable, and is designed to counter-balance a significant portion of its own weight in order to reduce the need for the robot's actuators to overcome gravitational forces. Finally, an inertial adaptive AAN controller is proposed and tested using dynamic simulations.
