In this respect, sensorized insoles also have a great potential for extracting gait information. This, combined with mathematical techniques based on machine learning (ML), can potentialize biomechanical analyses. The present study proposes a proof-of-concept of a system based on vertical ground reaction force (vGRF) acquisition with a sensorized insole that uses an ML algorithm to identify different patterns of vGRF and extract biomechanical characteristics that can help during clinical evaluation. The acquired data from the system was clustered by an immunological algorithm (IA) based on vGRF during gait. These clusters underwent a data mining process using the classification and regression tree algorithm (CART), where the main characteristics of each group were extracted, and some rules for gait classification were created. As a result, the system proposed was able to collect and process the biomechanical behavior of gait. After the application of IA and CART algorithms, six groups were found. The characteristics of each of these groups were extracted and verified the capability of the system to collect and process the biomechanical behavior of gait, offering verification points that can help focus during a clinical evaluation.A análise da marcha humana pode fornecer uma excelente fonte para identificar e prever patologias e lesões. Nesse aspecto, palmilhas sensorizadas também apresentam grande potencial para extrair informações da marcha.

O presente estudo propõe uma prova de conceito de um sistema baseado na aquisição de força de reação vertical do solo (vGRF) com palmilha sensorizada que utiliza um algoritmo ML para identificar diferentes padrões de vGRF e extrair características biomecânicas que podem auxiliar durante a avaliação clínica. Os dados adquiridos do sistema foram agrupados por um algoritmo imunológico (IA) baseado em vGRF durante a marcha. Esses clusters passaram por um processo de mineração de dados utilizando o algoritmo de árvore de classificação e regressão (CART), onde foram extraídas as principais características de cada grupo e criadas algumas regras para classificação da marcha. Como resultado, o sistema proposto foi capaz de coletar e processar o comportamento biomecânico da marcha. Após a aplicação dos algoritmos IA e CART, foram encontrados seis grupos. As características de cada um desses grupos foram extraídas e verificada a capacidade do sistema em coletar e processar o comportamento biomecânico da marcha, oferecendo pontos de verificação que podem auxiliar no foco durante uma avaliação clínica.CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorengUniversidade Federal de Minas GeraisUFMGBrasilEEF - DEPARTAMENTO DE FISIOTERAPIAENG - DEPARTAMENTO DE ENGENHARIA MECÂNICAInventionsFenômenos biomecânicosMarchaAnálise da marchaAprendizado de máquinaBiomechanics on gaitData miningGait analysisMachine learningSmart insoleDevelopment of a human motion analysis system based on sensorized insoles and machine learning algorithms for gait evaluationDesenvolvimento de um sistema de análise do movimento humano baseado em palmilhas sensorizadas e algoritmos de aprendizado de máquina para avaliação da marchainfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://www.mdpi.com/2411-5134/7/4/98Diego Henrique Antunes NascimentoFabrício Anicio MagalhãesGeorge Schayer SabinoRenan Alves ResendeMaria Lúcia Machado DuarteClaysson Bruno Santos Vimieiroapplication/pdfinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain;
