This book was released on 2022 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stroke is the leading cause of severe long-term disability worldwide. A commonly reported disability is hemiparesis. Impairments of the upper limb inhibit the individual's ability to perform activities of daily living; High-dose repetitive practice of functional tasks is important for recovery after stroke. This type of training is labor-intensive.Additionally, many stroke patients cannot complete traditional physical therapy due to the severity of their motor impairments. Robotics offers an alternative approach whereby assistance is provided via forces applied to the limb, allowing high dose and repetitive completion of movements that would otherwise be impossible to complete unassisted. However, even with the standardized rehabilitation programs that stakeholders implemented with robotic therapy, patients demonstrate variance in response to treatment due to the heterogeneous damage to the brain during the stroke. Subsequently, three studies investigated wearable robotics for stroke upper limb rehabilitation and the neural mechanisms of upper limb control and recovery. For the first study, 12 chronic stroke patients completed 8 weeks of at-home rehabilitation using a novel exoskeleton wearable robotic hand device that assisted with the opening of the hand-this enabled performance of therapeutic functional exercises. I examined the neural response to recovery using the neuroimaging technique electroencephalography. The study identified patients with the greatest operational hand improvements had the largest increase in interhemispheric sensorimotor communication. Additionally, neural biomarkers that could predict a patient's response to robotic therapy were identified. I performed biomechanic analysis using 3d motion capture and clinical evaluations without the device pre, post, and 3 months after completion of the study, which showed the novel device restored hand function. The second study saw the development of a new wearable robotic hand device that assists users with opening and closing motions. Additionally, an integrated Android app was developed, which could be used with the automated machine. The app has therapeutic video games and exercises to complement robotic therapy. The study gives a detailed evaluation of the mechanical and control system of the automated device and the responses of persons with the stroke that used the device. To better understand the neural process of upper limb recovery, the final study explored the neural pathways involved in grip force modulation and how robotics that offers upper limb gravity compensation alters the corticospinal path and neural activation. The studies show home-based robotic devices that can induce improvements in hand function after stroke and are well received by persons with stroke. Electroencephalography can be used to track the brain's plasticity during rehabilitation, identify biomarkers that predict response to therapy, and determine the influence of gravity compensation robotic devices on the corticospinal pathway. These findings may be of relevance for optimizing the design of rehabilitation robotics and neurorehabilitation programs.

Download or read book Exoskeletons in Rehabilitation Robotics written by Eduardo Rocon and published by Springer Science & Business Media. This book was released on 2011-01-19 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: Stroke is the major cause of disability in the world today, and it touches up to 110 000 persons every year, only in UK, and up to 70% of the survivors of a stroke suffer from a moderate to severe disabilities in their upper-limb motion control, caused by damages in the cerebral motor areas. The recovery of post-stroke impairments is a hard and long treatment, because the patient has to recover his physical strength and functionalities, but he also needs his affected neural area to reorganise, in order to make significant progresses. The rehabilitation techniques are many and all of them have their pros and cons, but the physiotherapists have more and more troubles in handling the growing number of patients. Indeed the majority of the patients suffering from a stroke are aged over 60, and the global ageing of the population implies an increase of those disabled people, creating a work load and a cost too great for the conventional rehabilitation techniques. The aim of this project is to investigate upper-limb rehabilitation techniques and in particular robot-assisted rehabilitation, to find out what could solve this major issue. The existing devices will be reviewed and robotic rehabilitation devices pointed as a solution for future post stroke recovery therapy. The concept of a soft robotic glove for hand rehabilitation, coupling a flexible structure with a cable-driven actuation will then be developed, and the methods of design of a prototype will be followed. Both the mechanical coupling between the hand and the glove, using vacuum and suctions cups, and the control interface of the prototype will be developed. Finally, despite the only partial achievement of the prototype, future prospective and use for this device will be discussed, concluding on the promising results obtained.

Available in PDF, EPUB and Kindle. Book excerpt: Current upper limb rehabilitation for stroke patients is based on a conventional physical therapy supervised by therapists. The most of the robot-based rehabilitation is developing under a bulky machine which is not suitable for home use. High rehabilitation fees and inconvenience in use lead patients from ordinary home to miss the suitable time in rehabilitation. This research explores an end-effector device which is light and suitable for the home environment. By balancing the contradiction of device function achievement and ordinary home use, this 3 DOF rehabilitation device is the appropriate choice for the current situation. Different with other low-cost devices in the markets, it can provide an assistant force in the recovery process. It makes severe patients can take passive rehabilitation exercises under totally device leading and minor stroke patients take active rehabilitation exercises by their own intention. After studying the upper limb motions in normal physical actions, the joint movement in those motions is discussed with details. Some effective recovery tasks are achieved by analyzing the conventional physical exercise for stroke. The research of human-machine interaction is conducted to reveal a method in interaction tasks design. The new version of device is designed and has the potential for better performance in structural stability, but the development in software and testing of new strategies are implemented on the old version because of funding issue. Different recovery patterns with different control strategies are exploited and compared in this article to select the appropriate training model in upper limb rehabilitation. The approach of novel human-machine interface, control strategy and upper limb recovery strategy built in this research offers a potential inspiration in upper limb rehabilitation device development.

Download or read book Robot assisted Therapy for Upper Limb Rehabilitation in Individuals with Stroke written by Nahid Norouzi Gheidari and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "In order to determine the effectiveness of robot-assisted therapy (RT) in upper limb (UL) rehabilitation of stroke patients, we first systematically reviewed and analyzed the literature. We found that when the duration/intensity of conventional therapy (CT) is matched with that of the RT, no difference exists between the intensive CT and RT groups in terms of motor recovery, activities of daily living, strength, and motor control. However, depending on the stage of recovery, extra sessions of RT in addition to regular CT are more beneficial than regular CT alone in motor recovery of the hemiparetic shoulder and elbow of patients with stroke; the gains are similar to those that have been observed in intensive CT. It has been shown that stroke patients with mild-to-moderate UL motor impairment benefit from training with a virtual reality rehabilitation system. However, during robot-assisted movements, it remains to be determined whether movements made in a virtual environment are similar to those made in a physical environment. Thus, we examined the role of training environment, whether virtual or physical, on robot-assisted reaching movements in chronic stroke and healthy individuals, within a single session. Fifteen subjects participated in this study divided into three groups: 5 chronic stroke individuals able to perform a reaching task with no need for the robot assistance, 5 chronic stroke individuals who needed the robot assistance to complete the reaching task, and 5 healthy individuals. The task was to reach for six target buttons in two identical physical and virtual environments. The outcomes consisted of kinematic measures and a custom questionnaire to assess how participants perceived and experienced the reaching task in both environments. We found no differences between the two environments in terms of the outcome measures in any of the groups. We concluded that the choice of environment, whether physical or virtual, is not a key factor in designing a robot-assisted reaching protocol for stroke survivors. Finally, we conducted a proof-of-concept study to identify clinical benefits and potential adverse effects of a novel, custom-developed RT protocol, named "Assist-As-Asked", aiming at improving arm function of chronic stroke subjects with moderate-to-severe UL motor impairment and to investigate whether practicing in a physical or virtual environment would make any difference in the outcomes of interest. Four chronic stroke subjects participated in 10 half-hour sessions to practice reaching six targets in both virtual and physical environments. The robotic arm provided gravity support, and with the "Assist-As-Asked" paradigm, helped subjects to complete movements when they requested it. Kinematics of the reaching movements and the subjects' perception about the reaching practice in both environments were the primary outcome measures of interest. Change in scores of FMA-UE was the secondary outcome measure. Following the RT sessions, all the subjects noticeably improved their reaching performance, which was accompanied by 3-5 points improvement in FMA-UE score. There were no differences between the two environments in terms of kinematic measures even though subjects had different opinions about environment preference. We concluded that moderate-to-severe chronic stroke survivors may benefit from RT using the "Assist-As-Asked" paradigm. In designing an RT platform for moderate-to-severe chronic stroke survivors, the choice of environment, either physical or virtual, does not necessarily influence the outcome of therapy sessions." --

Book excerpt: Robots have become an integral part of modern industrial manufacturing. In healthcare, the impact of robotic devices has not yet been established but there has been considerable discussion on their use as assistive devices and as products or systems that aid in rehabilitation of disabled people. I will technically investigate the current state-of-art wearable robotic devices in relation to physical rehabilitation and use of robots as assistive technology. Assistive technology is defined as use of a device to replace or to substitute function of missing limb of the user, and rehabilitation technology is the robotic device that should improve the individual's recovery of function. Wearable robots are generally electro-mechanical devices that are fitted to the user to facilitate rehabilitation or to allow the user to retrieve a lost or diminished capacity for purposeful movement. Wearable robots can be used either as an orthotic device; in case of dysfunction of limbs or as a prosthetic device that compensates for missing limbs following amputation. The challenges for the breakthrough of robotics into modern healthcare will be related to providing superior user interaction, ease of use and training and above all better functional outcome over that achievable by conventional rehabilitation methods or non-robotic assistive technologies. The project will review current commercial and disclosed research devices associated with upper limb and lower limb function. The field will be divided into functional categories related to reaching and grasping and standing and walking in exoskeleton and prosthetic devices. A key aspect of the review will focus on the mechanics and control approaches used to allow the user to train within a robotic system or control it to perform a task. The report will also critically look at solutions offered in relation to wearability, comfort and safety of use and the intended patient groups. Examples of the type of devices that will be included in the report are recent exoskeletons such as ReWalk from Argo Medical Technology, wearable walking robots such as KineAssist, MoonWalker as well as the more established body weight support treadmill training devices such as the Lokomat by Hocoma.

Download or read book Evaluating Robotic Assistance and Developing a Wearable Hand Activity Monitor to Improve Upper Extremity Movement Recovery After Stroke written by Justin Bradley Rowe and published by . This book was released on 2015 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: In their daily lives, stroke survivors must often choose between attempting upper-extremity activities using their impaired limb, or compensating with their less impaired limb. Choosing their impaired limb can be difficult and discouraging, but might elicit beneficial neuroplasticity that further reduces motor impairments, a phenomenon referred to as “the virtuous cycle”. In contrast, compensation is often quicker, easier, and more effective, but can reinforce maladaptive changes that limit motor recovery, a phenomenon referred to as “learned non-use”. This dissertation evaluated the role of robotic assistance in, and designed a wearable sensing system for, promoting the virtuous cycle. In the first half of the dissertation, we use the FINGER robot to test the hypothesis that robotic assistance during clinical movement training triggers the virtual cycle. FINGER consists of two singly-actuated mechanisms that assist individuated movement of the index and middle fingers. 30 chronic stroke participants trained in FINGER using a GuitarHero-like game for nine sessions. Half were guided by an adaptive impedance controller towards a success rate of 85%, while the other half were guided towards 50%. Increasing assistance to enable successful practice decreased effort, but primarily for less-impaired participants. Overall, however, high success practice was as effective (or more) as low success practice and even more effective for highly impaired individuals. Participants who received high assistance training were more motivated and reported using their impaired hand more at home. These results support the hypothesis that high assistance clinical movement training motivates impaired hand use, leading to greater use of the hand in daily life, resulting in a self-training effect that reduces motor impairment. The second half of the dissertation describes the development of the manumeter - a non-obtrusive wearable device for monitoring and incentivizing impaired hand use. Contrasted against wrist accelerometry (the most comparable technology), the manumeter uses a magnetic ring and a wristband with mangetometers to detect wrist and finger movement rather than gross arm movement. We describe 1) the inference of wrist and finger movement from differential magnetometer readings using a radial basis function network, 2) initial testing in which distance traveled estimates were within 94.7%±19.3 of their goniometricly measured values, 3) experiments with non-impaired participants in which the manumeter detected some functional activities better than wrist accelerometry, and 4) improvements to the hardware and data processing that allow both subject-independent tracking of the position of the finger relative to the wrist (RMS errors
Download or read book Wearable Robots written by José L. Pons and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: A wearable robot is a mechatronic system that is designed around the shape and function of the human body, with segments and joints corresponding to those of the person it is externally coupled with. Teleoperation and power amplification were the first applications, but after recent technological advances the range of application fields has widened. Increasing recognition from the scientific community means that this technology is now employed in telemanipulation, man-amplification, neuromotor control research and rehabilitation, and to assist with impaired human motor control. Logical in structure and original in its global orientation, this volume gives a full overview of wearable robotics, providing the reader with a complete understanding of the key applications and technologies suitable for its development. The main topics are demonstrated through two detailed case studies; one on a lower limb active orthosis for a human leg, and one on a wearable robot that suppresses upper limb tremor. These examples highlight the difficulties and potentialities in this area of technology, illustrating how design decisions should be made based on these. As well as discussing the cognitive interaction between human and robot, this comprehensive text also covers: the mechanics of the wearable robot and it’s biomechanical interaction with the user, including state-of-the-art technologies that enable sensory and motor interaction between human (biological) and wearable artificial (mechatronic) systems; the basis for bioinspiration and biomimetism, general rules for the development of biologically-inspired designs, and how these could serve recursively as biological models to explain biological systems; the study on the development of networks for wearable robotics. Wearable Robotics: Biomechatronic Exoskeletons will appeal to lecturers, senior undergraduate students, postgraduates and other researchers of medical, electrical and bio engineering who are interested in the area of assistive robotics. Active system developers in this sector of the engineering industry will also find it an informative and welcome resource.

Book excerpt: Physical rehabilitation for walking recovery after spinal cord injury is undergoing a paradigm shift. Therapy historically has focused on compensation for sensorimotor deficits after SCI using wheelchairs and bracing to achieve mobility. With locomotor training, the aim is to promote recovery via activation of the neuromuscular system below the level of the lesion. What basic scientists have shown us as the potential of the nervous system for plasticity, to learn, even after injury is being translated into a rehabilitation strategy by taking advantage of the intrinsic biology of the central nervous system. While spinal cord injury from basic and clinical perspectives was the gateway for developing locomotor training, its application has been extended to other populations with neurologic dysfunction resulting in loss of walking or walking disability.
