Desenvolvimento de protótipo de produto para testes de resistência, força e agilidade com aplicação no domínio da fisioterapia

Mestrado de dupla diplomação com a UTFPR - Universidade Tecnológica Federal do ParanáA utilização de testes de mobilidade, resistência e força em tratamentos fisioterapêu-ticos traz uma melhoria contínua das condições de mobilidade e força dos indivíduos. A correta execução destes testes e análise de seus resultados podem ser primordiais na recuperação de pacientes, para isso é necessário que se faça uso de equipamentos certi-ficados, calibrados e adequados. Esses testes podem ser realizados com um sistema de cadeira instrumentada, o Instituto Politécnico de Bragança possui um protótipoo da ca-deira instrumentada. O conceito de cadeira instrumentada varia de acordo com os tipos de testes que a mesma realiza, para esse trabalho a cadeira instrumentada realiza testes de mobilidade, força e resistência e tem o auxílio de sensores além de software para armazenamento de dados. A partir do exposto o objetivo desse trabalho é desenvolver o protótipo em estudo como produto de consumo com aplicação na fisioterapia. Foi reali-zada uma revisão sistemática na literatura sobre como esses testes são realizados, bem como os públicos-alvo e sua evolução. Além de propor melhorias mecânicas, visuais e ergonômicas ao sistema existente de cadeira instrumentada que é foco de uma análise SWOT realizada. A análise SWOT foi desenvolvida com base em pesquisa de opinião realizada através de um questionário, visando comparação com sistemas similares do mercado e a viabilidade do protótipo em estudo tornar-se produto de consumo. Com o levantamento bibliográfico, a realização da pesquisa de opinião e a análise SWOT, me-lhorias foram propostas para o protótipo. Conclui-se que as tecnologias, como sensores, são benéficas para a qualidade dos resultados dos testes, mas nem todas as alterações contribuem para o protótipo tornar-se produto de consumo.The use of mobility, resistance and strength tests in physiotherapy treatments brings a continuous improvement of the conditions of mobility and strength of the individuals. The correct execution of these tests and analysis of their results can be paramount in the recovery of patients, for this, it is necessary to make use of certified, calibrated and ade-quate equipment. These tests can be performed with an instrumented chair system, the Polytechnic Institute of Bragança has a prototype of the instrumented chair. The concept of instrumented chair varies according to the type of tests that it performs, for this work the instrumented chair performs tests of mobility, strength and resistance and has the aid of sensors as well as software for data storage. From the above, the objective of this work is to develop the prototype under study as a consumer product with application in physiotherapy. A systematic review was carried in the literature on how these tests are performed, as well as the target audiences and their evolution. In addition to propose mechanical, visual and ergonomic improvements to the existing system of instrumented chair that is the focus of SWOT analysis. The SWOT analysis was developed based on an opinion survey conducted through a questionnaire, aiming to compare with similar market systems and the possibility of the prototype under study becomes consumer product. With the bibliographical survey, the survey of opinion and the SWOT analysis, improvements were proposed for the prototype. It was concluded that technologies, such as sensors, are benefical to the quality of test results, but not all changes contribute to the prototype become a consumer product

An Evaluation of Hand-Force Prediction Using Artificial Neural-Network Regression Models of Surface EMG Signals for Handwear Devices

Hand-force prediction is an important technology for hand-oriented user interface systems. Specifically, surface electromyography (sEMG) is a promising technique for hand-force prediction, which requires a sensor with a small design space and low hardware costs. In this study, we applied several artificial neural-network (ANN) regression models with different numbers of neurons and hidden layers and evaluated handgrip forces by using a dynamometer. A handwear with dry electrodes on the dorsal interosseous muscles was used for our evaluation. Eleven healthy subjects participated in our experiments. sEMG signals with six different levels of forces from 0 N to 200 N and maximum voluntary contraction (MVC) are measured to train and test our ANN regression models. We evaluated three different methods (intrasession, intrasubject, and intersubject evaluation), and our experimental results show a high correlation (0.840, 0.770, and 0.789 each) between the predicted forces and observed forces, which are normalized by the MVC for each subject. Our results also reveal that ANNs with deeper layers of up to four hidden layers show fewer errors in intrasession and intrasubject evaluations
