[Abstract] Design and Development of a Robot Guided Rehabilitation Scheme for Upper Extremity Rehabilitation
To rehabilitate individuals with impaired upper-limb function, we have designed and developed a robot guided rehabilitation scheme. A humanoid robot, NAO was used for this purpose. NAO has 25 degrees of freedom. With its sensors and actuators, it can walk forward and backward, can sit down and stand up, can wave his hand, can speak to the audience, can feel the touch sensation, and can recognize the person he is meeting. All these qualities have made NAO a perfect coach to guide the subjects to perform rehabilitation exercises. To demonstrate rehabilitation exercises with NAO, a library of recommended rehabilitation exercises involving shoulder (i.e., abduction/adduction, vertical flexion/extension, and internal/external rotation), and elbow (i.e., flexion/extension) joint movements was formed in Choregraphe (graphical programming interface). In experiments, NAO was maneuvered to instruct and demonstrate the exercises from the NRL. A complex ‘touch and play’ game was also developed where NAO plays with the subject that represents a multi-joint movement’s exercise. To develop the proposed tele-rehabilitation scheme, kinematic model of human upper-extremity was developed based modified Denavit-Hartenberg notations. A complete geometric solution was developed to find a unique inverse kinematic solution of human upper-extremity from the Kinect data. In tele-rehabilitation scheme, a therapist can remotely tele-operate the NAO in real-time to instruct and demonstrate subjects different arm movement exercises. Kinect sensor was used in this scheme to get tele-operator’s kinematics data. Experiments results reveals that NAO can be tele-operated successfully to instruct and demonstrate subjects to perform different arm movement exercises. A control algorithm was developed in MATLAB for the proposed robot guided supervised rehabilitation scheme. Experimental results show that the NAO and Kinect sensor can effectively be used to supervise and guide the subjects in performing active rehabilitation exercises for shoulder and elbow joint movements.

[Abstract + References] Virtual System Using Haptic Device for Real-Time Tele-Rehabilitation of Upper Limbs – Conference paper
This paper proposes a tool to support the rehabilitation of upper limbs assisted remotely, which makes it possible for the physiotherapist to be able to assist and supervise the therapy to patients who can not go to rehabilitation centers. This virtual system for real-time tele-rehabilitation is non-invasive and focuses on involving the patient with mild or moderate mobility alterations within a dynamic therapy based on virtual games; Haptics Devices are used to reeducate and stimulate the movement of the upper extremities, at the same time that both motor skills and Visual-Motor Integration skills are developed. The system contains a virtual interface that emulates real-world environments and activities. The functionality of the Novint Falcon device is exploited to send a feedback response that corrects and stimulates the patient to perform the therapy session correctly. In addition, the therapy session can vary in intensity through the levels presented by the application, and the amount of time, successes and mistakes made by the patient are registered in a database. The first results show the acceptance of the virtual system designed for real-time tele-rehabilitation.

[Abstract] Home-based tele-rehabilitation presents comparable and positive impact on self-reported functional outcomes as center-based rehabilitation: Singapore tele-technology aided rehabilitation in stroke (STARS) trial
Stroke is a leading cause of disability worldwide. Functional, financial and social barriers commonly prevent individuals with acute stroke and disabilities from receiving rehabilitation following their hospital discharge. Home-based rehabilitation is an alternative to center-based rehabilitation but it is often costlier. Tele-rehabilitation is a promising solution for optimizing rehabilitation utilization, as it can enable clinicians to supervise patients and conversely, patients to receive the recommended care remotely. Our team therefore developed a novel tele-rehabilitation, with the primary aim to estimate the extent to which the proposed tele-rehabilitation resulted in an improvement in function during the first three-months after stroke in comparison to usual rehabilitation.
Material and method
This was a randomized controlled trial. We used the Late-Life Function and Disability Instrument (FDI) to assess our primary outcome (with adjustment made for baseline covariate).
We recruited 124 participants and randomized them to receive either 12-week home-based tele-rehabilitation or usual rehabilitation.
Over the 12-week rehabilitation period, the intervention group spent 2246-minutes on their rehabilitation whereas the control group spent 2565-minutes. The median difference between the two groups was not statistically significant (P = 0.649).
Primary Outcome (FDI)
The mean FDI frequency score post-rehabilitation for the intervention and control groups were 39.7 (SD 11.7) and 43.0 (SD 10.6) respectively. The mean FDI limitation score post-rehabilitation for the intervention group was 78.5 (SD 20.6) and that for the control group was 85.4 (SD 19.6). The unadjusted and adjusted differences in both FDI scores between the two groups were not statistically significant (Models 1 and 2).
Both groups reported comparable amount of time spent on rehabilitation and similarly positive impact on the primary outcome. Home-based tele-rehabilitation can be an effective strategy for minimizing or eliminating rehabilitation utilization barriers while achieving the same functional outcome as center-based rehabilitation.

The impairment of finger movements after a stroke results in a significant deficit in hands everyday performances. To face this kind of problems different rehabilitation techniques have been developed, nevertheless, they require the presence of a therapist to be executed. To overcome this issue have been designed several apparatuses that allow the patient to perform the training by itself. Thus, an easy to use and effective device is needed to provide the right training and complete the rehabilitation techniques in the best way. In this paper, a review of state of the art in this field is provided, along with an introduction to the problems caused by a stroke and the consequences for the mobility of the hand. Then follows a complete review of the low cost home based exoskeleton project design. The objective is to design a device that can be used at home, with a lightweight and affordable structure and a fast mounting system. For implementing all these features, many aspects have been analysed, starting from the rehabilitation requirements and the ergonomic issues. This device should be able to reproduce the training movements on an injured hand without the need for assistance by an external tutor.
Instead of grappling with limited mobility to attend physical therapy sessions, recovering patients can don VR gear as part of rehab, potentially enabling remote therapy and treatment from the privacy of their homes thanks to Verizon’s latest lab project
Most patients who are recovering from serious surgery must go through some form of rehabilitation. These patients are often hindered in their mobility, making getting to and from places a challenge. Professor Steven Feiner and his students at Verizon‘s incubator lab Alley are working on a potential virtual rehab program that could make life easier for both those patients and their therapists.
The program works by “creating a collaborate virtual environment in which the therapist and patient use virtual reality to perform exercises focused on motor rehabilitation when they’re both in different locations.” While this ability would have been unthinkable just a few years ago, the advances in both VR as well as the incredible speed of a 5G connection have made it something possible to test out.
The potential benefits are obvious for both the patient and therapist. Rather than having to leave the home with limited mobility, patients could perform their rehab in their home by simply donning VR eyewear. Doctors and therapists also would be able to take on more patients, as their sessions become more streamlined. While this idea is still in the testing stage, it has the potential to optimize—if not—revolutionize a crucial aspect of healthcare.

Tele-rehabilitation for stroke survivors has emerged as a promising intervention for remotely supervised administration of physical, occupational, speech, and other forms of therapies aimed at improving motor, cognitive, and neuropsychiatric deficits from stroke.
We aimed to provide an updated systematic review on the efficacy of tele-rehabilitation interventions for recovery from motor, higher cortical dysfunction, and poststroke depression among stroke survivors.
We searched PubMed and Cochrane library from January 1, 1980 to July 15, 2017 using the following keywords: “Telerehabilitation stroke,” “Mobile health rehabilitation,” “Telemedicine stroke rehabilitation,” and “Telerehabilitation.” Our inclusion criteria were randomized controlled trials, pilot trials, or feasibility trials that included an intervention group that received any tele-rehabilitation therapy for stroke survivors compared with a control group on usual or standard of care.
This search yielded 49 abstracts. By consensus between 2 investigators, 22 publications met the criteria for inclusion and further review. Tele-rehabilitation interventions focused on motor recovery (n = 18), depression, or caregiver strain (n = 2) and higher cortical dysfunction (n = 2). Overall, tele-rehabilitation interventions were associated with significant improvements in recovery from motor deficits, higher cortical dysfunction, and depression in the intervention groups in all studies assessed, but significant differences between intervention versus control groups were reported in 8 of 22 studies in favor of tele-rehabilitation group while the remaining studies reported nonsignificant differences.
This updated systematic review provides evidence to suggest that tele-rehabilitation interventions have either better or equal salutary effects on motor, higher cortical, and mood disorders compared with conventional face-to-face therapy.
