[ARTICLE] A Systematic Review of Usability and Accessibility in Tele-Rehabilitation Systems – Full Text

Abstract

The appropriate development of tele-rehabilitation platforms requires the involvement and iterative assessments of potential users and experts in usability. Usability consists of measuring the degree to which an interactive system can be used by specified final users to achieve quantified objectives with effectiveness, efficiency, and satisfaction in a quantified context of use. Usability studies need to be complemented by an accessibility assessment. Accessibility indicates how easy it is for a person to access any content, regardless of their physical, educational, social, psychological, or cultural conditions. This chapter intends to conduct a systematic review of the literature on usability and accessibility in tele-rehabilitation platforms carried out through the PRISMA method. To do so, we searched in ACM, IEEE Xplore, Google Scholar, and Scopus databases for the most relevant papers of the last decade. The main result of the usability shows that the user experience predominates over the heuristic studies, and the usability questionnaire most used in user experience is the SUS. The main result of the accessibility reveals that the topic is only marginally studied. In addition, it is observed that Web applications do not apply the physical and cognitive accessibility standards defined by the WCAG 2.1.

1. Introduction

Innovation and technological advances involve the offering of valuable products and services to improve the quality of life of citizens. In recent decades, the domain of telemedicine has reported advances in the control, monitoring and evaluation of various clinical conditions [1]. In the field of rehabilitation, numerous studies and state-of-the-arts from informatics perspective [2] and different areas of application [34], show the effectiveness and advantages of the use of remote rehabilitation (or tele-rehabilitation) [56]. Tele-rehabilitation aims to reduce the time and costs of offering rehabilitation services. The main objective is to improve the quality of life of patients [7]. Tele-rehabilitation cannot replace traditional neurological rehabilitation [8]. It is considered as a partial replacement of face-to-face physical rehabilitation [9]. Tele-rehabilitation uses mainly two groups of technologies: (1) wearable devices and (2) vision-based systems based on depth cameras and intelligent algorithms [10]. In [5], the authors describe and analyze some characteristics and typical requirements tele-rehabilitation systems.

Design and conception of tele-rehabilitations platforms that do not consider guidelines, metrics, patterns, principles, or practice success factors can affect the access to the service, the effectiveness, quality, and usefulness. It can cause problems of confusion, error, stress, and abandonment of the rehabilitation plan. Therefore, guaranteeing the correct use of these applications implies to incorporate different studies of usability in the life cycle of the interactive system. For this reason, aspects of human factors engineering in tele-rehabilitation systems have been studied with the aim of providing accessible, efficient, usable and understandable systems [1112].

User-centered agile development (UCD) approaches allows developers to specify and design the set of interfaces of any interactive system in a flexible and effective way [1314]. The agile development life cycle centered on user experience (UX-ADLC) allows iteratively evaluating system interfaces based on the results of the previous iteration. The evaluation also includes the errors and usability problems encountered [15]. Thus, usability studies are an essential aspect of technology development [16]. This is the reason why designers need to meet usability and user experience objectives while adhering to agile principles of software development. Formative and summative usability tests are methods of evaluating software products widely adopted in user-centered design (UCD) [15] and agile UX development lifecycle. Both approaches are frequently used in the development of software applications. Rapid formative usability should be carried out so as to fulfill UX goals while satisfying end users’ needs. Formative usability is used as an iterative test-and-refine method performed in the early steps of a design process, in order to detect and fix usability problems [15]. Summative usability allows for assuring, in later phases of the design, the quality of the user experience (UX) for a software product in development. The focus is on short work periods (or iterations) where usability tests (formative and summative) must be contemplated. This means that quick formative usability tests should be carried out to fulfill UX goals [17].

The ISO 9241-11 standard [18] is a framework for understanding and applying the concept of usability to situations in which people use interactive systems and other types of systems (including built environments), products (including industrial and consumer products) and services (including technical and personal services). Likewise, the usability standard ISO 9241-11 facilitates the measurement of the use of a product with the aim of achieving specific objectives with effectiveness, efficiency and satisfaction in a context of specific use [18].

Usability can be studied through software evaluation methods widely accepted in user centered design (UCD) [15]. It can be formative or summative [8]. Formative usability consists of a set of iterative tests carried out in the early stages of the design process. The aim of the tests is to refine and improve the software product, as well as to detect and solve potential usability problems. As a complement, the summative usability allows to obtain an evaluation of the user experience (UX) for a software product in development. Formative usability facilitates decision making during the design and development of the product, while summative usability is useful when studying user experience (UX).

Tullis and Stetson [19] evaluated the effectiveness of the most used questionnaires to measure the summative usability. The authors found that the System Usability Scale (SUS) [20] and the IBM Computer System Usability Questionnaire (CSUQ) [21] are the most effective. SUS provides a quick way for measuring the usability through user experience. It consists of a 10-item questionnaire with 5-likert scale range from “Strong Agree” to “Strongly Disagree.” The CSUQ focuses on three main aspects: (1) the utility, which refers to the opinion of users regarding the ease of use, the ease of learning, the speed to perform the operations, the efficiency in completing tasks and subjective feeling; (2) the quality of the information which studies the subjectivity of the user regarding the management of system errors, the clarity of the information and the intelligibility; and finally, (3) the quality of the interface which measures the affective component of the user’s attitude in the use of the system.

Large part of the tasks in the tele-rehabilitation systems are carried out by patients who require to treat a temporary disability. Considering the special needs of these users, usability evaluations alone cannot guarantee an appropriate design of the system. On the contrary, accessibility studies can provide the mechanisms to offer the same means of use to all users of any interactive system. A study combining usability and accessibility was presented in [22]. The study analyzes how remote and/or video monitoring technologies affect the accessibility, effectiveness, quality and usefulness of the services offered by tele-rehabilitation systems. To do this, the authors provide an overview of the fundamentals necessary for the analysis of usability, in addition to analyzing the strengths and limitations of various tele-rehabilitation technologies, considering how technologies interact with the clinical needs of end users such as accessibility, effectiveness, quality and utility of the service [22].

For many people, the Web is a fundamental part of everyday life. Therefore, a fundamental aspect to ensure the inclusivity of a Website is its accessibility. For example, people who cannot use their arms to write on their computer can use a mouth pencil [23]. Or someone who cannot listen well can use subtitles to understand a video. Also, a person who has a low vision can use a screen reader to listen what is written on the screen [24]. Therefore, Web accessibility means that people with disabilities can use the Web without any type of barriers [24]. There are several standards related to accessibility that provide guidelines and recommendations [25]. Some of the most important, according to the International Organization for Standardization (ISO), are the following ones:

  • ISO 9241: covers ergonomics of human-computer interaction.

  • ISO 14915 (software ergonomics for multimedia user interfaces): multimedia controls and navigation structure.

  • ISO CD 9241-151 (software ergonomics for World Wide Web user interfaces): designs of Web user interfaces.

  • ISO TS 16071 (guidance on accessibility for human-computer interface): recommendations for the design of systems and software applications that allows a greater accessibility to computer systems for users with disabilities.

  • ISO CD 9241-20: accessibility guideline for information communication, equipment and services.

The Web Accessibility Initiative (WAI) [26] from the World Wide Web Consortium (W3C) [27] develops Web Content Accessibility Guidelines (WCAG) [28] 2.0 (at present 2.1) that covers a wide range of recommendations for making Web contents more accessible. These guidelines were considered a standard in 2012, the ISO/IEC 40500. Complementary to these guidelines are the W3C User Agent Accessibility guidelines [29] (UAAG) and Authoring tool Accessibility guidelines [30] (ATAG), which addresses the current technological capabilities to modify the presentation based on the device capabilities and the preferences of the user.

The World Wide Web Consortium (W3C) provides international standards to make the Web as accessible as possible. It comprises the Web 2.0 Content Accessibility Guidelines (WCAG 2.0) [31], also known as the ISO 40500 [32], which are adapted to the European Standard called EN 301549 [33].

The current version of the accessibility guidelines is “Web Content Accessibility Guidelines 2.1” (WCAG 2.1) [23]. WCAG 2.1 consists of 4 principles, 13 guidelines and 76 compliance criteria. The four principles refer to [34].

Principle 1—perceptibility: refers to the good practices regarding the presentation of information and user interface components. It consists of 4 guidelines and 29 compliance criteria.

Principle 2—operability: the components of the user interface and navigation must be operable. It includes 5 guidelines and 29 compliance criteria.

Principle 3—comprehensibility: the information and user interface management must be understandable. It has 3 guidelines and 17 compliance criteria.

Principle 4—robustness: the content must be robust enough to rely on the interpretation of a wide variety of user agents, including assistive technologies. It includes a guideline and three compliance criteria.

Usability and accessibility can be combined to achieve the development of more accessible, efficient, equitable and universal tele-rehabilitation systems. This chapter presents a systematic literature review of summative and formative usability studies as well as accessibility studies in the context of tele-rehabilitation systems. The remaining of the manuscript is composed of four sections. Section 2 presents the method used to proceed with the systematic review. Section 3 is a description of the most relevant papers in usability applied to tele-rehabilitation. Section 4 describes the results regarding the accessibility. And Section 5 draws conclusions on the main findings of this literature review.[…]

[Abstract + References] Virtual System Using Haptic Device for Real-Time Tele-Rehabilitation of Upper Limbs

Abstract

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 + References] Upper-Limb Tele-Rehabilitation System with Force Sensorless Dynamic Gravity Compensation

Abstract

Tele-rehabilitation provides remote physiotherapy services for patients who have limited access to hospitals. This paper proposes a sensorless tele-rehabilitation system for the upper-limb using two robots in master–slave configuration. The system provides a transparent haptic feeling between the therapist and the patient by simultaneous tracking of both position and torque. The torque is measured using the reaction torque observer. Furthermore, an online recursive numerical parameter estimation method is proposed to identify the gravity disturbance in bilateral teleoperation. The system automatically estimates the parameters using the reaction torque observer output’s data while the therapist is delivering remote physiotherapy services. The estimated gravity torque is compensated in the system as an improvement of the transparency of the teleoperated system. Therefore the therapist would feel only the abnormalities of the patient’s arm. Estimated parameters automatically update the system and enhance the performance. The proposed method was practically verified with a master slave tele-rehabilitation system. Results suggest the applicability of the proposed method.

[Abstract] Acceptance of Tele-Rehabilitation by Stroke Patients: Perceived Barriers and Facilitators

Abstract

Objective

To explore the perceived barriers and facilitators of tele-rehabilitation (TR) by stroke patients, caregivers and rehabilitation therapists in an Asian setting.

Design

Qualitative study involving semi-structured in-depth interviews and focus group discussions.

Setting

General community.

Participants

Participants (N=37) including stroke patients, their caregivers, and tele-therapists selected by purposive sampling.

Interventions

Singapore Tele-technology Aided Rehabilitation in Stroke trial.

Main Outcome Measures

Perceived barriers and facilitators for TR uptake, as reported by patients, their caregivers, and tele-therapists.

Results

Thematic analysis was used to inductively identify the following themes: facilitators identified by patients were affordability and accessibility; by tele-therapists, was filling a service gap and common to both was unexpected benefits such as detection of uncontrolled hypertension. Barriers identified by patients were equipment setup–related difficulties and limited scope of exercises; barriers identified by tele-therapists were patient assessments, interface problems and limited scope of exercises; and common to both were connectivity barriers. Patient characteristics like age, stroke severity, caregiver support, and cultural influence modified patient perceptions and choice of rehabilitation.

Conclusions

Patient attributes and context are significant determinants in adoption and compliance of stroke patients to technology driven interventions like TR. Policy recommendations from our work are inclusion of introductory videos in TR programs, provision of technical support to older patients, longer FaceTime sessions as re-enforcement for severely disabled stroke patients, and training of tele-therapists in assessment methods suitable for virtual platforms.

[SHORT ARTICLE] Tele rehabilitation: two-year experience in conducting medical assessments via tele link

by Nalinda Andraweera, Consultant Physician in Rehabilitation Medicine,
Modbury Public Hospital, Adelaide, Australia.

Introduction

Telemedicine has been practised for many
decades since initial documentation in 1940s when
radiology images were sent between two townships
in Pennsylvania via telephone lines. Bioinstrumentation and transmission of astronauts’ vital parameters to ground based flight surgeons came to
forefront during NASA’s space programme in 1960s.
During following decades, telemedicine was used in
multiple medical specialties as a mode of patient
assessment. Use of telemedicine in Rehabilitation
Medicine is relatively recent. As multidisciplinary
coordinated care led by rehabilitation physicians and
allied clinicians is required, proformas are used in
tele rehabilitation assessments. Proformas help to
generate a clinical document with medical and allied
health assessments in one clinical record. Currently,
delivery of rehabilitation services is further empowered, enhanced and in evolution with the installation of dedicated software programmes for use by
allied health clinicians. Most units operating tele
medicine for rehabilitation medical services use
trained proctor with the client/patient to enable
more comprehensive examination to aid clinical
decision when the physician is stationed in a distant
site.

Evidence

Current evidence based on multi centre trials
suggest that well conducted tele rehabilitation enable
clinical outcomes similar to face to face rehabilitation.
Advantages of tele rehabilitation being low cost and
the ability to provide an increased volume of therapy
[1]. Drawbacks include limitations in detailed examination and negative implications in rehabilitation goal setting. If patients are reviewed early, frequent
and active communication is carried out during tele
rehabilitation, patient centred goal setting can be
improved [2].

Methodology

Client assessments were from a city Hospital in
Adelaide (Modbury Hospital) linked via a video link
to a regional general hospital (Riverland General
Hospital in Berri) 241 kilometres from Adelaide.
Period assessed is from May 2016 to September 2018.
Fortnightly tele ward rounds and additional initial
inpatient and outpatient assessments were conducted via a video link. Both inpatient and outpatientclients were informed and educated about method of
tele medicine and tele rehabilitation and consent was
obtained for video-based assessments with the
physician. A trained proctor was present at each
assessment.
Tele rehabilitation services were provided using
a secure, encrypted platform with privacy and
confidentiality maintained. Video link was established via a licenced communication provider enabling an uninterrupted video connection linking
patient and proctor with the physician. Electronic
transfer of clinical records was done using a secure
health email platform.
Trained proctor was a clinical nurse practitioner,
physiotherapist or an occupational therapist trained
to aid in clinical examinations required for musculoskeletal and neurological examination. Proformas were emailed to the physician prior to patient
assessment with medical history, current vital
parameters, medications and initial allied health
assessments. Video based clinical assessments were
recorded in a client proforma and a clinical report
was generated. Radiology and haematology/
biochemistry investigations were reviewed using a
medial investigation software used in South
Australian Health Service (Oasis). Urgent images
requested by the physician were done locally or at a
private service provider and snip tooled using a
licenced health imaging access pathway. Allied
health clinicians recorded initial functional levels
using FIM (Functional Independent Measure).
Following patient assessment, patient centred
realistic goals were discussed with the patient and
the multi-disciplinary team via video link.

Results

Assessments done from 18 May 2016 to 17
September 2018 were assessed. A total of 236 Tele
medicine assessments were completed for patients/
clients admitted for rehabilitation. Average duration
for an assessment was 26 minutes. Patient satisfaction
on telemedicine assessments was 100%.

Conclusion

Tele medical assessments of patients admitted
for rehabilitation is currently gaining momentum and
more health funding is allocated for further expansion
of tele medicine and tele rehabilitation. Carrying out
medical assessments via a licenced video linkage
allows clients/patients to be reviewed with minimal
delay, closer to their homes and without the need to
travel to a specialist centre in a city. Tele medical
assessments save time for physicians as no travel time
is required, objective assessments can be done
effectively with the help of a trained proctor. Assessment reports can be generated with minimal delay using proformas and electronically transferred to
local GPs and multidisciplinary rehabilitation team
members comprising physiotherapists, occupational
therapists, nurse practitioners, social workers and
nutritionists/dieticians. Tele medical assessments in
rehabilitation aid uninterrupted rehabilitation service
provision in a distant site. Patient satisfaction is high.

[WEB SITE] HOMEREHAB – Development of Robotic Technology for Post-Stroke Home Tele-Rehabilitation – The European Coordination Hub for Open Robotics Development

homerehab1

Rehabilitation can help hemiparetic patients to learn new ways of using and moving their weak arms and legs. With immediate therapy it is also possible that people who suffer from hemiparesis may eventually regain movement. However, reductions in healthcare reimbursement place constant demands on rehabilitation specialists to reduce the cost of care and improve productivity. Service providers have responded by shortening the length of patient hospitalisation.

The HOMEREHAB project will develop a new tele-rehabilitation robotic system for delivering therapy to stroke patients at home. It will research on the complex trade-off between robotic design requirements for in home systems and the performance required for optimal rehabilitation therapies, which current commercial systems designed for laboratories and hospitals do not take into account. Additionally, the new home scenario also demands for the smart monitoring of the patient’s physiological state, and the adaptation of the rehabilitation therapy for an optimal service.

[Abstract] Tele-Rehabilitation after Stroke: An Updated Systematic Review of the Literature

Abstract

BACKGROUND:

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.

OBJECTIVE:

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.

METHODS:

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.

RESULTS:

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.

CONCLUSION:

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.

[BLOG POST] Advantages of incorporating tele-rehabilitation into healthcare

The technology applied to the field of rehabilitation provides multiple benefits for both the health system and the patient.  Next, we explain why tele-rehabilitation will help optimize healthcare resources and improve patients’ quality of life.

A better picture: lack of specialists and long waiting lists in rehabilitation

“The Spanish health system is not prepared to respond to the advance of medical rehabilitation and the epidemic of disability due to ageing,” concluded the Spanish Society for Rehabilitation and Physical Medicine (Sermef) in its latest edition held from 30 May to 1 June in Gijón (Asturias).

This shortage throughout the country requires incorporating tele-rehabilitation into the Spanish health system.  However, Manuel Rodríguez-Piñero, from Sermef’s board of directors, stated, “the Rehabilitation services suffer from technological obsolescence, which, if not taken care of, will become obsolete and out of the 21st century”. Such as this news from ABC in Seville underlines, the director added: “The integration of robotics or virtual reality systems into rehabilitation assistance, to give two examples, are common to all European rehabilitation centers and is, unfortunately, the story of our hospitals”.

Sermef calls for unified action to improve the detection and treatment of disability situations and to promote a reorganization of rehabilitation for rational care, as well as an adequate definition of portfolios of services and procedures that allow efficient management. 

Recently, La Sexta Noticias also announced that the lack of physiotherapists, the number of chronically ill, and the current model of care contribute to the congestion of the centers and, consequently, a delay of more than two months for rehabilitation in public health care. Professionals stress the importance of receiving physical therapy on time, and more so after an operation. Failure to do so can have lifelong consequences.

How to solve it: distance rehabilitation therapies

Remote rehabilitation or tele-rehabilitation consists, in the first place, of diagnosing possible musculoskeletal pathologies through wearable sensors that record movements in real time and in a very precise way. The medical report is then shared with the physical therapist to determine the type of exercises the patient should follow. Through the internet connection, the patient can access a space, where he can easily find the exercises so he can do them whenever and wherever he wants, and he can consult with the doctor whenever the need.

DyCare wanted to bet on ReHub, a new solution based on an online platform that allows connecting the patient, the physiotherapist and the doctor. It facilitates the execution of the rehabilitation treatment from home, and it is always monitored by the rehabilitation professional.

Silvia Raga, CEO of the company, comments: “Our goal is to offer products of value to the patient. We want to show objective data to offer more personalized treatments for the patient, and, at the same time, contribute to savings in the health system”. With this in mind, DyCare does not lose focus on transforming the future of rehabilitation by developing the first digital solution for distance physical rehabilitation therapies.

Eight advantages of tele-rehabilitation

  1. Storage of and access to the patient’s medical records from any location
  2. A personalized program of the rehabilitation exercises, specifically adapted to the patient’s physical condition
  3. Real-time control and monitoring of the patient by the expert
  4. Remote adaptation of the exercises
  5. Continuous interaction between doctor, physiotherapist and patient
  6. Patient empowerment and adherence to treatment thanks to the biofeedback they receive in real time during the execution of the exercises
  7. Comfort when performing the exercises as they can be done where and when the patient wants
  8. Savings in travel costs and waiting time

If you have any questions or if you would like to receive more information from DyCare ReHub, please do not hesitate to contact us, we will be happy to contact you.

[ARTICLE] Low Cost Device for ”At Home” Rehabilitation After a Stroke Event – Full Text PDF

Abstract

The paper proposes a design solution for a low cost device with feedback for upper extremity rehabilitation after a stroke event. Cerebral vascular accident (CVA) or stroke is one of the leading causes of morbidity and mortality worldwide. CVA is the most important cause of long-term disability in Europe, and demographic changes have led to an increase in both incidence and prevalence of this. Most secondary stroke disability is recovered in a few months, but others may persist for life. The rehabilitation should be started as soon as there is a greater chance of recovery in this early stage. Disabilities get worse and remain permanent over time, which is why is recommended the establishment of a rehabilitation program as soon as possible. Today, the use of virtual reality environments allow patients to perform tasks that mimic real life in rehabilitation clinics, but it tends increasingly more in the future these tasks can be done at home, sending data and receiving feedback from doctors. The devices presented in this paper are not only mechanical devices that allow the movement on a certain direction with predetermined effort degree for the patient, possibly controlled by the force of the muscle activity (EMG), but are innovative devices with the possibility to record a full set of biomedical signals. The patient device can record one or more biomedical parameters such as electrocardiography (ECG), heart rate (HR), electromyography (EMG), non-invasive blood pressure (NIBP), oxygen concentration in the blood (SpO2), movement speed and acceleration, angle of motion of a body extremity, torsion, s.a. according to the physician’s prescription and the patient needs. This means that the patient device will be very flexible and can communicate with other medical devices for home use.

[Abstract + References] Virtual System Using Haptic Device for Real-Time Tele-Rehabilitation of Upper Limbs – Conference paper

Abstract

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.
