[Abstract] Delivering Remote Rehabilitation at Home: An Integrated Physio-Neuro Approach to Effective and User Friendly Wearable Devices – SpringerLink

Abstract

There is a global shortage of manpower and technology in rehabilitation to attend to the five million new patients who are left disabled every year with stroke. Neuroplasticity is increasingly recognized to be a primary mechanism to achieve significant motor recovery. However, most rehabilitation devices either limit themselves to mechanical repetitive movement practice at a limb level or focus only on cognitive tasks. This may result in improvements in impairment but seldom translates into effective limb and hand use in daily activities. This paper presents an easy-to-use, wearable upper limb system, SynPhNe (pronounced like “symphony”), which trains brain and muscle as one system employing neuroplasticity principles. A summary of clinical results with stroke patients is presented. A new, wireless, home-use version of the solution architecture has been proposed, which can make it possible for patients to do guided therapy at home and thus have access to more therapy hours.

[WEB SITE] RAPAEL Smart Glove Receives CES 2017 Innovation Award – Rehab Managment

The RAPAEL Smart Glove, a wearable device from NEOFECT, Burlingame, Calif, offers at-home game-based hand therapy for stroke patients who cannot visit a clinic due to economic or geographic reasons.

Simply wear the glove, connect to the “RAPAEL” app, and play the rehabilitation games.

The Smart Glove—a CES 2017 Innovation Awards Honoree for the hospital edition—leads the patient through games that stimulate daily activities, in one or two 30-minute sessions per day.

Built-in sensors capture the patient’s movement and positioning data, and transfer it via Bluetooth to a tablet, where it is analyzed. This analysis enables the games’ difficulty levels to be adjusted and the patient’s exercise schedule to be customized.

Training movements include forearm supination/pronation, wrist flexion/extension, wrist radial/ulnar deviation, and finger flexion/extension, per the company’s website.

[WEB SITE] “Virtual physiotherapist” helps paralysed patients exercise using computer games – Medical News Today

A simple device can improve the ability of patients with arm disability to play physiotherapy-like computer games, according to new research.

The low-cost invention, called gripAble™, consists of a lightweight electronic handgrip, which interacts wirelessly with a standard PC tablet to enable the user to play arm-training games. To use it, patients squeeze, turn or lift the handgrip, and it vibrates in response to their performance whilst playing. The device uses a novel mechanism, which can detect the tiny flicker movements of severely paralysed patients and channel them into controlling a computer game.

Special-training computer games, controlled by the device, have been designed for people with no previous experience of using computers. For example one computer game requires the user to squeeze repeatedly to slowly reveal a photograph.

In a new study published in PLOS ONE, researchers from Imperial College London have shown that using the device increased the proportion of paralysed stroke patients able to direct movements on a tablet screen by 50 per cent compared to standard methods. In addition, the device enabled more than half of the severely disabled patients in the study to engage with arm-training software, whereas none of the patients were able to use conventional control methods such as swiping and tapping on tablets and smartphones.

Over five million people in the UK live with arm weakness – approximately one million of them following a stroke, plus others who have neurological and musculoskeletal conditions. Arm weakness contributes to physical disability that requires expensive long-term care. For example, treatment for stroke costs the NHS £9 billion a year, which is five per cent of the total NHS budget. The only intervention shown to improve arm function is repetitive, task-specific exercise but this is limited by the cost and availability of physiotherapists.

The gripAble™ device is designed for patients to use unsupervised in hospital and at home. The research tested the gripAble™ device with stroke patients who had suffered successive strokes with arm paralysis at Imperial College Healthcare NHS Trust over six months. The researchers assessed their ability to use gripAble™ to control mobile gaming devices such as tablets that could be used for rehabilitation and compared this to their use of conventional methods such as swiping and tapping.

They found that 93 per cent of patients were able to make meaningful movements to direct the cursor as a result of using gripAble™. In contrast, 67 per cent of patients were able to use mobile gaming devices by swiping on a tablet. For other types of control over the tablet, such as tapping or using joysticks, the number of patients able to make meaningful movements was lower.

The success of the device was most apparent for patients with severe arm weakness: no patients in this group were able to use conventional controls to play training games, whereas 58% could use gripAble™.

In a smaller sub-group the trial also demonstrated that severely disabled patients could play computer games that involve tracking a target with almost as good accuracy as healthy people.

The clinical trial was carried out at Charing Cross Hospital, part of Imperial College Healthcare Trust, between 2014 and 2015. The team is now carrying out a feasibility study in North West London to test the use of the device in patients’ homes.

The potential of gripAble™ as a means of delivering cost-effective physiotherapy was recognised by a NHS England Innovation Challenge Prize in early 2016.

Lead researcher Dr Paul Bentley, who is a Clinical Senior Lecturer at Imperial College London and Honorary Consultant Neurologist at Imperial College Healthcare NHS Trust , said: “In the UK 100,000 new cases of arm weaknesses are diagnosed each year following a stroke. Often this impairs people’s ability to carry out daily activities, requiring long-term care. The use of mobile-gaming could provide a cost-effective and easily available means to improve the arm movements of stroke patients but in order to be effective patients of all levels of disability should be able to access it.

“We have developed the gripAble™ device to improve arm and cognitive function of patients who have mild to severe arm weaknesses. Unlike other therapies currently on the NHS, gripAble™ is a low cost device which can be used in hospitals and independently by patients at home. As such it could potentially help save the health service millions of pounds. We now intend to further develop the device so we can help more patients who are currently suffering from the effects of poor arm and upper body mobility.”

The researchers collaborated with Human Robotics Group at Imperial College London to develop the device. The research is funded by the Imperial Confidence in Concept Award, the NHS England Innovation Challenge Prize, and the EU 7th Framework Programme for Research and Technological Development grants.

The gripAble™ device is an example of the work of the Imperial Academic Health Science Centre (AHSC). This is a partnership between Imperial College London and three NHS Trusts, which aims to improve patient outcomes by harnessing scientific discoveries and translating them as quickly as possible into new diagnostics, devices and therapies, in the NHS and beyond. The researchers are working with Imperial Innovations, the College’s technology transfer partner, to spinout gripAble™ as a digital healthcare start-up to commercialise the device.

[ARTICLE] Use of NeuroEyeCoach™ to Improve Eye Movement Efficacy in Patients with Homonymous Visual Field Loss – Full Text

Abstract

Visual field deficits are common in patients with damaged retinogeniculostriate pathways. The patient’s eye movements are often affected leading to inefficient visual search. Systematic eye movement training also called compensatory therapy is needed to allow patients to develop effective coping strategies. There is a lack of evidence-based, clinical gold-standard registered medical device accessible to patients at home or in clinical settings and NeuroEyeCoach (NEC) is developed to address this need. In three experiments, we report on performance of patients on NEC compared to the data obtained previously on the earlier versions of the search task (); we assessed whether the self-administered computerised tasks can be used to monitor the progress () and compared the findings in a subgroup of patients to a healthy control group. Performance on cancellation tasks, simple visual search, and self-reported responses on activities of daily living was compared, before and after training. Patients performed similarly well on NEC as on previous versions of the therapy; the inbuilt functionality for pre- and postevaluation functions was sensitive to allowing assessment of improvements; and improvements in patients were significantly greater than those in a group of healthy adults. In conclusion, NeuroEyeCoach can be used as an effective rehabilitation tool to develop compensatory strategies in patients with visual field deficits after brain injury.

1. Introduction

We explore our surrounding environment by moving our eyes on average three times per second. The eye movement episodes are punctuated by brief periods (100–300 ms) of fixations. This pattern of activity ensures detailed image processing by the high density cone-receptor region of our central vision [1]. The resultant continuous perception of the stable world relies on amalgamation of lower resolution peripheral vision with high resolution central information in a spatiotopic frame of reference [2]. This dynamic process encompasses the suppression of noise or distractors and selective enhancement of target objects [3]. The selection of candidate targets for subsequent eye movements (saccades) is achieved through a combination of stimulus driven bottom-up and goal driven top-down mechanisms [4].

Visual field deficits often accompany lesions of the visual pathways which in turn disrupt the selection of targets falling within the impaired visual fields [5]. Abnormal patterns of eye movement are reported in approximately 60% of such cases [6]. One method for quantifying disturbances of visual processing is to make use of a visual search paradigm where the patient is required to report the presence or absence of a target amongst distractor items, often but not exclusively, presented on a computer screen [7]. The reaction times are then compared to those for target detection in the sighted field in the same individual or in a group of healthy individuals. The inverse of the slope for a linearly fitted plot of reaction times as a function of the number of distractor items reflects “search efficiency” [8]. In general, for healthy adults when targets and distractors are easily discriminable (pop-out search), the slope is shallow (high efficiency), but steeper slopes are expected when targets and distractors share features (complex or conjunction search).

Eye movement recordings of patients with visual field deficits following brain injury reveal a number of characteristics [9]. These include smaller saccade amplitudes, and, hence, a larger number of fixations; limited exploration of the contralesioned visual field; and more between-hemifield saccades often summarised as disorganised eye movements leading to slower reaction times for targets in contralesioned hemifields. Disturbances of eye movement dynamics are also reported in the sighted (ipsilesioned) hemifield [6, 10].

In clinical practice, the rehabilitation of patients with visual field deficits is often conducted by occupational therapists or low-vision experts. The aim of any intervention is to improve the patient’s interactions with their immediate surrounding and increasing their confidence in tasks such as shopping or commuting. The use of computerised visual search tasks as a rehabilitation tool to improve eye movements after brain injury was first reported in a group of 30 patients [11]. Patients were given systematic practice with large saccadic eye movements to search for targets presented at unpredictable positions in both the affected hemifield and the entire field of gaze. This class of treatment was later extended by use of a visual search paradigm to improve scanning strategy. Simultaneous recording of eye movements in a group of 60 patients provided further evidence for spatially disorganised pattern of eye movements in 60% of cases [6], with improved visual scanning in all 13 cases that underwent visual search training. With better use of the remaining sight as well as efficient search strategy, patients were able to compensate for their partial blindness; hence, the technique has been termed compensatory. This technique with various modifications has been used in 14 studies to date, with a total of 593 patients with homonymous visual field loss and persistent visual disabilities (see Table 1). Indeed a recent systematic review [12] has identified eye movement training as the most promising approach to visual rehabilitation in stroke patients.

[ARTICLE] Effect of home-based training using a slant board with dorsiflexed ankles on walking function in post-stroke hemiparetic patients – Full Text PDF

Abstract.

[Purpose] To investigate the effects of a 30-day rehabilitation program using a slant board on walking function in post-stroke hemiparetic patients.

[Subjects and Methods] Six hemiparetic patients with gait disturbance were studied. The patients were instructed to perform a home-based rehabilitation program using a slant board, thrice daily for 30 days, the exercise included standing on the slant board for 3 minutes, with both ankles dorsiflexed without backrest. For all patients, the Brunnstrom Recovery Stage, Barthel Index, range of motion of the ankle joint, modified Ashworth scale scole for calf muscle, sensory impairments with Numeral Rating Scale, maximum walking speed, number of steps, and Timed “Up and Go” test were serially evaluated at the beginning and end of the 30-day program.

[Results] The program significantly increased walking velocity, decreased the number of steps in the 10-m walking test, and decreased Timed “Up and Go” test performance time.

[Conclusion] This rehabilitation program using the slant board was safe and improved walking function in patients. The improvement in walking function could be due to a forward shift of the center of gravity, which can be an important part of motor learning for gait improvement.
INTRODUCTION

Fig. 1. The slant board used in this study The slant angle was set at 20 degrees

Stroke is a leading cause of long-term disability, and the absolute number of patients with stroke is increasing. Of the neurological sequelae that cause functional disability, hemiparesis is the most common. The incidence of gait disturbance due to hemiparesis is reportedly relatively high among chronic stroke patients1, 2). The occurrence of this disability leads to marked impairment of quality of life and the sense of well-being3, 4). In addition, the burden of caregivers is anticipated to increase when patients are in need of assistance for walking5). Improved walking ability is one of the most common goals for post-stroke hemiparetic patients6, 7). A slant board has been used as a therapeutic device for patients with spastic lower hemiparesis. Standing on the toe-up inclination surface stretches the calf muscles, which reduces the pathologically increased lower limb muscle tone in post-stroke hemiparetic patients. Standing without a back rest on the slant board can produce a forward shift in the center of pressure in healthy adults and hemiparetic patients, as reported in our previous study. Kluzak reported that standing on an inclined surface resulted in an after-effect of learning in healthy, blindfolded subjects when they returned to standing on a horizontal surface8). Subjects leaned forward after they stood on a toes-up inclination surface. Recent reports described other benefits of using the board in healthy adults and hemiparetic patients, such as movement of “center of pressure”9), and possible increase in the maximum range of “center of gravity” in the antero-posterior direction10).
Neurophysiological studies have also demonstrated increased contraction of the anterior tibialis muscle in healthy subjects standing on the slant board11). Daily home-based rehabilitation using the slant board was hypothesized to improve gait in post-stroke hemiparetic patients. To test the hypothesis, the present study investigated the effects of a 30-day home-based daily rehabilitation program using the slant board on walking function in post-stroke hemiparetic patients.

[ARTICLE] SCRIPT passive orthosis: design of interactive hand and wrist exoskeleton for rehabilitation at home after stroke – Full Text PDF

Abstract

Recovery of functional hand movements after stroke is directly linked to rehabilitation duration and intensity. Continued therapy at home has the potential to increase both. For many patients this requires a device that helps them overcome the hyperflexion of wrist and fingers that is limiting their ability to open and use their hand. We developed an interactive hand and wrist orthosis for post-stroke rehabilitation that provides compliant and adaptable extension assistance at the wrist and fingers, interfaces with motivational games based on activities of daily living, is integrated with an off-the-shelf mobile arm support and includes novel wrist and finger actuation mechanisms. During the iterative development, multiple prototypes have been evaluated by therapists in clinical settings and used intensively and independently by 33 patients at home. This paper details the final design of the SCRIPT passive orthosis resulting from these efforts.

[Final Report Summary] REHAB@HOME (Engaging Game-based Home Rehabilitation for Improved Quality of Life) – European Commission : CORDIS : Projects & Results Service  

Executive Summary:

The project was focussing on solutions for patients after a stroke to supply them with a sustainable progress in rehabilitation. The research refers to the upper part of the body, especially the movement of the arms, the grip and the wrists. As medical and technical partners are involved in this project as well as patients, an ongoing rehabilitation process can be evaluated in depth. The project’s aim was to design and develop an open- solution IT-device (concept, hardware/software) that allows the patient to exercise at home to reduce his disabilities. The device offers features and functionalities as a set of exercises based on personalised serious games adapted to the patient’s needs. The challenge on the one side was to develop games which are motivating for the patient and allow him to improve at the same time. The plan is to have the first training with the device during the patient’s stay at the hospital, enabling him to continue his training at home. The games used for a patient are selected individually by the physician and are calibrated to the patient’s needs and abilities, ensuring and optimum degree of exercise.. The player collects rewards as a real-time feedback during his training. As a socialisation component, the patient can also compete with friends or family members.

During the training with this user-friendly IT-device, information about the quality of the performance is provided to the medical personnel. The physical and medical parameters are monitored and evaluated by an on-line/off-line management at the medical centre. The rehabilitation protocol provides a good overview of the patient’s progress to the medical personnel and allows the challenges of the games to be adjusted to the patient’s condition.
The device consists of commercial products like Microsoft KinectTM and using Web2.0 social networks. In this way an effective, efficient and attractive virtual environment for a successful rehabilitation can be built at the patient’s home. Because of the individual handicaps of the game’s users, the challenge was to optimise the games in such way that the training is sufficient for the patient and has enough stimulation to keep the patient exercising. The components themselves are low-cost, robust, good to handle and easy to use. Also, the therapeutic data, physical as well as physiological, are collected via the sensors, and are evaluated with the software developed during the project In this way the medical care can be online as well as off-line. The result of this new kind of service model proposed by Rehab@Home targeting the new technology, coupled with training, demonstration and dissemination will be the integration in the existing public healthcare service.Project Context and Objectives:
In 1997 the number of over-65 year olds constituted 6.6%of the world’s population, and this is predicted to increase to 10% by 2025. It is expected that this will lead to a rise in demand for long-term residential care. Common elderly diseases and ailmentsinclude one or more of the following: arthritis, cancer, cardiovascular (e.g. blood pressure and heart disease), cerebrovascular (e.g. strokes), dementia, depression, diabetes, falls and injuries, gastrointestinal disorders, hearing impairment, memory, osteoporosis, Parkinson’s and Alzheimer’s diseases, respiratory disease, pressure ulcers, sleep problems, thyroid disease, urinary disorders and visual impairment. In many cases, considerable health gain, both from the physical and cognitive perspectives, can be achieved by successful rehabilitation, which is concerned with lessening the impact of specific disabling conditions.
Considering that the aforementioned set of diseases is very broad, to the Rehab@Home project focussed more on one specific indication, stroke. Stroke is the 2nd most common cause of death in Europe (1.24 million annual) and in the European Union (508,000 annual) and the 3rd cause of death in Canada (14,000 annual) and the United States (over 143,000 people each year). Meanwhile, 1.8% of Asians aged 18 years and older have had a stroke. In general, according to the World Health Organization, about 15 million people suffer from stroke worldwide each year. Of these, 5 million die, 10 million survive, though showing different degrees of disabilities. Accordingly, the costs of stroke are enormous. In Europe and the USA, 2-6% of all health care costs are spent on direct stroke care, including the costs of hospital and nursing home care, the services of physicians and other medical professionals, drugs, appliances, and rehabilitation. (Evers S, et. al., “International Comparison of Stroke Cost Studies,” Stroke 35:1209-15, 2004.) Indirect costs, defined as production losses, further increase the burden of the disease. In Europe, direct costs are in the range of 3.000-16.000 Euros per patient during the first year, whereas the lifetime direct cost may reach 30.000 Euros. Taken together, direct and indirect costs may be as high as 20.000-26.000 Euros per patient in the first year. In Europe, 22 billion Euros are spent on stroke annually (Truelsen T, et al., “Cost of stroke in Europe,” Eur. J. Neuro. 12, Suppl 1:78-84, 2005).
Stroke affects everybody differently, and it is difficult to say how much of a recovery is possible. Many stroke survivors experience the most dramatic recovery during their stay in hospital in the weeks after their stroke. But many stroke survivors continue to improve over a longer time, sometimes over a number of years. The goal of rehabilitation is to help survivors become as independent as possible and to attain the best possible quality of life. Rehabilitation does not “cure” stroke in that it does not reverse brain damage. High quality rehabilitation however is essential to regain many – if not all – of their capabilities.
The first stage of rehabilitation usually occurs within an acute-care hospital, as soon as the patient is stable and the (initially high) risk of recurrence is lower. 10% of the survivors can return home quickly, many need to be treated in some type of medical facility. For over half of the of stroke survivors, rehabilitation will be a long-term process requiring work with therapists and specialized equipment for months or (ideally) years after the stroke.
However, increasing cost pressure on the health system will lead to shorter periods of intensive rehabilitation at specialized facilities. Within this context the adoption of suitable technical aids at home, together with a proper training program, can help reducing the patient’s stay at the hospital as well as the need for moving him/her between home and a physiotherapy unit or a paramedical structure.
Rehabilitation, which may be effective in improving the physical and mental condition of older people in long-term care, is a complex set of procedures usually involving several professional disciplines and aimed at improving the quality of life of older people facing daily living difficulties caused by either temporary and/or chronic diseases. Comprehensive rehabilitation needs to address a number of different levels which may be contributing to loss of function: the damaged body part and other related body elements, psychological attitudes, immediate material environment (e.g. clothing items), the surrounding indoor environment (e.g. housing/equipment), external environment (e.g. shops, social outlets), social support networks.
In the specific case of stroke, rehabilitation is based on Neuroplasticity (also known as cortical re-mapping), which is the brain’s ability to reorganize itself by forming new connections, allowing nerve cells in the brain to compensate for defects. However, neuroplasticity is only happening when there is ‘right’ stimulus and sustainable motivation, which are the key factors of successful rehabilitation. Rehabilitation teaches new ways of performing tasks to circumvent or compensate for any residual disabilities. There is a strong consensus among rehabilitation experts that the most important element in any rehabilitation program is carefully directed, well-focused, repetitive practice – the same kind of practice used by all people when they learn any new skill, such as playing guitar or skating.

[Abstract] Stroke rehabilitation at home before and after discharge reduced disability and improved quality of life: a randomised controlled trial

Abstract

Objective: To evaluate if home-based rehabilitation of inpatients improved outcome compared to standard care.

Design: Interventional, randomised, safety/efficacy open-label trial.

Setting: University hospital stroke unit in collaboration with three municipalities.

Subjects: Seventy-one eligible stroke patients (41 women) with focal neurological deficits hospitalised in a stroke unit for more than three days and in need of rehabilitation.

Interventions: Thirty-eight patients were randomised to home-based rehabilitation during hospitalization and for up to four weeks after discharge to replace part of usual treatment and rehabilitation services. Thirty-three control patients received treatment and rehabilitation following usual guidelines for the treatment of stroke patients.

Main measures: Ninety days post-stroke the modified Rankin Scale score was the primary endpoint. Other outcome measures were the modified Barthel-100 Index, Motor Assessment Scale, CT-50 Cognitive Test, EuroQol-5D™, Body Mass Index and treatment-associated economy.

Results: Thirty-one intervention and 30 control patients completed the study. Patients in the intervention group achieved better modified Rankin Scale score (Intervention median = 2, IQR = 2-3; Control median = 3, IQR = 2–4; P=0.04). EuroQol-5D™ quality of life median scores were improved in intervention patients (Intervention median = 0.77, IQR = 0.66–0.79; Control median = 0.66, IQR = 0.56 – 0.72; P=0.03). The total amount of home-based training in minutes highly correlated with mRS, Barthel, Motor Assessment Scale and EuroQol-5D™ scores (P-values ranging fromP<0.00001 to P=0.01). Economical estimations of intervention costs were lower than total costs of standard treatment.

Conclusion: Early home-based rehabilitation reduced disability and increased quality of life. Compared to standard care, home-based stroke rehabilitation was more cost-effective.
