Exoskeletons with virtual reality, augmented reality and gamification for stroke patients' rehabilitation : systematic review

Background: Robot-assisted therapy has become a promising technology in the field of rehabilitation of post-stroke patients with motor disorders. Motivation during the rehabilitation process is a top priority for a majority of stroke survivors. With the advancement in technology, there has been the introduction of Virtual Reality, Augmented Reality, customizable games or a combination thereof that aid robotic therapy in retaining or increasing the interests of patients to keep performing the exercises. However, there are gaps in evidence regarding the transition from clinical rehabilitation to home-based therapy and it calls for an updated synthesis of literature showcasing this trend. The present review proposes a categorization of these studies according to technologies used by them and also details research in upper limb and lower limb applications. Objective: The goal of this work was to review the practices and technologies implemented for the rehabilitation of post-stroke patients. It aims to assess the effectiveness of exoskeleton robotics in conjunction with any of the three technologies, Virtual Reality, Augmented Reality or Gamification for improving activity and participation in post-stroke survivors. Methods: A systematic search of the literature on exoskeleton robotics applied with any of the three technologies, Virtual Reality, Augmented Reality or Gamification, was performed in the databases namely; MEDLINE (Medical Literature Analysis and Retrieval System Online, or MEDLARS Online), EMBASE (Excerpta Medica database), Science Direct & The Cochrane Library. Exoskeleton based studies that did not include any VR, AR or gamification elements were excluded and publications from the year 2010 to 2017 were included. Results in the form of improvements in patients were also recorded and taken into consideration in finding the effectiveness of therapy on patients. Results: Thirty studies were identified based on the inclusion criteria that included randomised controlled trials as well as explorative research pieces. There was a total of around 385 participants across the studies. Use of technologies such as Virtual Reality/Augmented Reality/Gamification based Exoskeletons are capable of filling the transition from clinical to home-based settings. Our analysis showed that there were in general improvements in the motor deficiency for patients using the novel interfacing techniques with exoskeletons. This categorization of studies helps in understanding the scope of rehabilitation therapies that can be successfully arranged for home-based rehabilitation. Conclusions: Future studies are necessary to explore various types of customizable games required to retain or increase the motivation of patients going through the therapy individually

This article presents a broad contextualization of robots in healthcare by identifying key stakeholders, care settings, and tasks; reviewing recent advances in healthcare robotics; and outlining major challenges and opportunities to their adoption.Comment: 8 pages, Communications of the ACM, 201

Robot Assisted Shoulder Rehabilitation: Biomechanical Modelling, Design and Performance Evaluation

The upper limb rehabilitation robots have made it possible to improve the motor recovery in stroke survivors while reducing the burden on physical therapists. Compared to manual arm training, robot-supported training can be more intensive, of longer duration, repetitive and task-oriented. To be aligned with the most biomechanically complex joint of human body, the shoulder, specific considerations have to be made in the design of robotic shoulder exoskeletons. It is important to assist all shoulder degrees-of-freedom (DOFs) when implementing robotic exoskeletons for rehabilitation purposes to increase the range of motion (ROM) and avoid any joint axes misalignments between the robot and human’s shoulder that cause undesirable interaction forces and discomfort to the user. The main objective of this work is to design a safe and a robotic exoskeleton for shoulder rehabilitation with physiologically correct movements, lightweight modules, self-alignment characteristics and large workspace. To achieve this goal a comprehensive review of the existing shoulder rehabilitation exoskeletons is conducted first to outline their main advantages and disadvantages, drawbacks and limitations. The research has then focused on biomechanics of the human shoulder which is studied in detail using robotic analysis techniques, i.e. the human shoulder is modelled as a mechanism. The coupled constrained structure of the robotic exoskeleton connected to a human shoulder is considered as a hybrid human-robot mechanism to solve the problem of joint axes misalignments. Finally, a real-scale prototype of the robotic shoulder rehabilitation exoskeleton was built to test its operation and its ability for shoulder rehabilitation

Then, I briefly speculate on how the field might make progress going forward, highlighting the need for new models of training and learning driven by big data, better personalization and targeting, and an increase in the quantity and quality of usability and uptake studies to improve translation

A flexible sensor technology for the distributed measurement of interaction pressure

We present a sensor technology for the measure of the physical human-robot interaction pressure developed in the last years at Scuola Superiore Sant'Anna. The system is composed of flexible matrices of opto-electronic sensors covered by a soft silicone cover. This sensory system is completely modular and scalable, allowing one to cover areas of any sizes and shapes, and to measure different pressure ranges. In this work we present the main application areas for this technology. A first generation of the system was used to monitor human-robot interaction in upper- (NEUROExos; Scuola Superiore Sant'Anna) and lower-limb (LOPES; University of Twente) exoskeletons for rehabilitation. A second generation, with increased resolution and wireless connection, was used to develop a pressure-sensitive foot insole and an improved human-robot interaction measurement systems. The experimental characterization of the latter system along with its validation on three healthy subjects is presented here for the first time. A perspective on future uses and development of the technology is finally drafted
