Quick Abstract

This article presents the development of a wearable and portable system, the Ortho-Monitorizer, which allows an objective, continuous and simultaneous monitoration of the temperature and pressure exerted on the skin on the 3 main pressure points derived from the use of a hand and wrist orthosis. It also allows the monitorization of the patient’s compliance to the orthosis, providing its time of use. This way, adjustments to the orthosis can be optimized, reducing the discomfort felt by the patient, increasing compliance, reducing the risk of pressure sores’ formation derived from inadequate levels of pressure applied, and consequently, increasing the effectiveness of orthosis’ use. Therefore, an Arduino Uno, powered by a powerbank, is used as microcontroller. Three force sensors and three temperature sensors are controlled by the microcontroller to detect the pressure and temperature. A Bluetooth Low Energy module is used to send data from the Arduino to an android application under development, which will allow healthcare professionals to consult all the information and clinical history relating to each patient, as well as allowing the patient to develop a greater awareness and sense of responsibility regarding their performance in relation to the guidelines provided by the health professional.

Quick Abstract

Currently, pain analysis in a clinical environment is not common and is at fault for being subjective and always dependent on a personal response. Therefore, it is imperative to use physiological signals to quantify pain and make diagnosis more objective. This article aims to study the relationship between pain, through its analog scale, with the electrodermal and cardiac signals of individuals characterized by having a shoulder pathology that gives rise to recurrent pain. This study was carried out on 21 patients from Hospital Curry Cabral, who were part of the Occupational Therapy department’s care in the area of Physical Medicine and Rehabilitation, and 18 individuals without any pathology, thus serving as a control group. All participants followed an experimental protocol consisting in the measurement of electrodermal and cardiac signals and pain level when performing two different movements. The results suggest that there is indeed a relationship between the two measured signals and pain. The greater the pain experienced by the individual, the greater the amplitude of the electrodermic signal and heart rate appears to be.

Quick Abstract

Visual impairments affect the life of millions of people. Some of these impairments can be corrected or diminished. Visual stimulation is one way of visual rehabilitation, that has produced better results when used in the early years of life. As there is nothing standardized in this field, a platform named RehabVisual was developed (Machado et al., 2018; Santos, 2018). This platform has the objective of creating an individual visuomotor rehabilitation for children under two years old, that were born prematurely. In order to reach a therapists' need, a video analysis tool was developed. This tool should be capable of following the motion of the patients' eyes, with the purpose of facilitating and making the analysis of their reactions to the stimuli more objective. The solution developed on this paper consists on the creation of an eye tracker system, that does not need to be pre-calibrated and is low-cost. The eye tracker was tested in healthy individuals and the results show that is very effective in detecting horizontal eye variations.

Quick Abstract

Spinal cord injuries are one of the most traumatic situations with a major impact on a person's quality of life. This type of injury have a extremely impact in the performance of daily life activities not only due to motor alterations but also due to the appearance of neuropathic pain Throughout the rehabilitation process the evaluation and intervention methodologies are not very systematic and are not personalized. Thus, to bridge this gap, the VR4NeuroPain was developed a technology that associates virtual reality with a glove "GNeuroPathy". The glove "GNeuroPathy" allows the collection of physiological parameters, namely to identify the electrodermic activity (EDA) while the patient carries out activities in an immersive environment. The main objective of this article is to present the validation process of the "GNeuroPathy" in clinical context. "GNeuroPathy" was applied to a group of 17 individuals with incomplete spinal cord injury. The results showed that "GNeuroPathy" is easy to apply and is suitable for comfort and texture. Data were also collected from EDA and it was found that there is a significant difference in signal amplitude in patients with low and high functionality.

Quick Abstract

With the increase of evidence-based practice, the registration and dissemination of the assessment data, became more and more important. In paediatric rehabilitation those procedures are particularly important since they allow for an initial characterization of the clinical situation, to compare results in different assessment moments and to disseminate the evaluation outcomes. However, in several kinds of evaluation, data registration is a complex and slow process. Similarly, the comparison of raw score to standard score can be very time consuming. To minimize that challenge it is important to develop a digital system that makes the registration fast and objective. The main purpose of this paper is to present VMSReport: an application to registrate visuomotor performance data, visual perception, as well as and motor coordination, in children aged 2 years and older. That digital tool allows also to compare results between various moments of assessment and can automatically generate a report for each evaluation. It also builds a database, which facilitates the process of global data analysis and modelling. This tool was developed in a clinical environment, giving clear answers to requests from rehabilitation caregivers. A pilot study, with 10 children, has already been carried out. The VMSReport can now be used.

Quick Abstract

Technology has played an increasingly important role in the health sector, with new devices allowing for better real-time monitoring of patients’ biosignals. Among those, the ones developed with perfusion in mind are extremely useful, during cardiothoracic surgery, since they provide detailed information about the vital signs of the patient. However, doctors and technicians have often to calculate several physiological parameters, which help them make clinical decision during such surgical interventions. In this context, the authors present a software tool – BioMEP: Perfusion Calculator Application, built in a partnership between the Department of Cardiothoracic Surgery of Santa Marta Hospital and the Department of Physics of the Faculty of Sciences and Technology of the NOVA University of Lisbon, and which fulfils the needs of the surgical team. BioMEP - Perfusion Calculator Application is a safe, intuitive and user-friendly tool that incorporates and integrates department-specific perfusion parameters and calculations, in a single platform, and allows for higher intervention efficiency, while minimizing the errors of the required calculation, with the concomitant improvement in patient safety.

Quick Abstract

The stimulation of visuomotor skills has a relevant role in the rehabilitation of children with neurological dysfunctions / pathologies. However, the methods of evaluation and intervention for children under the age of 18 months are few systematic and not directed to the problem of each one. For this reason it was important to develop a system that will fill this gap. Therefore, the main purpose of this paper is to present the development process of a tool called RehabVisual - evaluation and stimulation of visuomotor competences. RehabVisual has the objective to promote the evaluation and the stimulations of visuomotor skills in children between the ages of 0 and 18 months. The platform has two sessions: database that records all the clinical information of the child and protocol with stimuli according to the development of the child. This plataform it was realized with physicians and occupations therapists from the Service of Physical Medicine and Rehabilitation (PMR) of the Hospital D. Estefânica of the Hospital Center of Lisbon Central and it was approved by the Portuguese Ethics Committees of this Hospital. The RehabVisual can be used by physicians, occupational therapists, and caregivers and is characterized for being a tool user-friendly, versatile and adaptable to the needs of each child.
