Solução para classificação de posturas de pessoas acamadas baseada em mapas de ...
Fonseca, Luís Filipe RodriguesO campo das tecnologias de informação está em constante evolução, e é notável a sua expansão no campo da saúde. Esta dissertação foca-se em demonstrar como os métodos de classificação de posturas baseados em mapas de pressão de pessoas acamadas podem contribuir para melhorar não apenas os cuidados prestados aos pacientes, mas também aliviar a carga de trabalho dos profissionais de saúde. Este relatório descreve...
Pressure-based posture classification methods and algorithms: a systematic review
Fonseca, Luís Filipe Rodrigues; Ribeiro, Fernando Reinaldo; Metrôlho, J.C.M.M.There are many uses for machine learning in everyday life and there is a steady increase in the field of medicine; the use of such technologies facilitates the tiresome work of health professionals by either automating repetitive tasks or making them simpler. Bed-related disorders are a great example where tedious tasks could be facilitated by machine learning algorithms, as suggested by many authors, by provid...
Integrated system for pressure ulcers monitoring and prevention
Fonseca, Luís Filipe Rodrigues; Ribeiro, Fernando Reinaldo; Metrôlho, J.C.M.M.; Fidalgo, Filipe; Dionísio, Rogério Pais; Silva, Arlindo F.Pressure ulcers are a critical issue for patients and healthcare professionals, requiring their frequent monitoring, with a consequent impact on healthcare costs. This problem has been gaining attention and approaches have been proposed, using sensor-based systems, to facilitate this monitoring and help health caregivers to achieve greater effectiveness in the treatment of this type of ulcer. In this paper, the...
A novel elastic sensor sheet for pressure injury monitoring: design, integratio...
Mohammad Amini, Mohammad; Devin, Mohammad Ghassem Farajzadeh; Alves, Paulo; Sheikholeslami, Davood Fanaei; Hariri, Fatemeh; Dionísio, Rogério PaisThis study presents the SENSOMATT sensor sheet, a novel, non-invasive pressure monitoring technology intended for placement beneath a mattress. The development and design process of the sheet, which includes a novel sensor arrangement, material selection, and incorporation of an elastic rubber sheet, is investigated in depth. Highlighted features include the ability to adjust to varied mattress sizes and the in...
Effects of the number of classes and pressure map resolution on fine-grained in...
Fonseca, Luís Filipe Rodrigues; Ribeiro, Fernando Reinaldo; Metrôlho, J.C.M.M.In-bed posture classification has attracted considerable research interest and has significant potential to enhance healthcare applications. Recent works generally use approaches based on pressure maps, machine learning algorithms and focused mainly on finding solutions to obtain high accuracy in posture classification. Typically, these solutions use different datasets with varying numbers of sensors and classi...
PoPu-Data: a multilayered, simultaneously collected lying position dataset
Fonseca, Luís Filipe Rodrigues; Ribeiro, Fernando Reinaldo; Metrôlho, J.C.M.M.; Santos, Adriana; Dionísio, Rogério Pais; Amini, MohammadThis study presents a dataset containing three layers of data that are useful for body position classification and all uses related to it. The PoPu dataset contains simultaneously collected data from two different sensor sheets—one placed over and one placed under a mattress; furthermore, a segmentation data layer was added where different body parts are identified using the pressure data from the sensors over ...
Lying-people pressure-map datasets : a systematic review
Fonseca, Luís Filipe Rodrigues; Ribeiro, Fernando Reinaldo; Metrôlho, J.C.M.M.Bedded or lying-people pressure-map datasets can be used to identify patients’ in-bed postures and can be very useful in numerous healthcare applications. However, the construction of these datasets is not always easy, and many researchers often resort to existing datasets to carry out their experiments and validate their solutions. This systematic review aimed to identify and characterise pressure-map datasets...
Innovation and knowledge transfer for monitoring, predicting and preventing ulc...
Silva, Arlindo F.; Santos, Osvaldo; Ribeiro, Fernando Reinaldo; Fidalgo, Filipe; Metrôlho, J.C.M.M.; Amini, Mohammad; Fonseca, Luís Filipe RodriguesPressure ulcers are skin injuries that develop mainly over bony areas as the result of prolonged pressure caused by the immo- bility of bedridden patients. They constitute not only a source of additional suffering for these patients but also contribute to the burnout of healthcare professionals who must maintain continuous monitoring of these patients. Data from countries such as the UK or the USA allows the co...
