Abstract

Purpose: to identify and describe wearable electronic devices used for monitoring mastication and swallowing in adults.

Methods: two independent researchers searched the PubMed and MEDLINE engines via Ovid®. Primary studies were selected using Rayyan®, with analysis of titles, abstracts, and full texts. The information extracted followed a study protocol.

Literature Review: 243 studies, of which 25 were selected for analysis after applying the inclusion and exclusion criteria, were identified. Data about the participants, devices, sensors, location, and analyses performed, were extracted.

Conclusions: wearable devices for monitoring mastication have been used primarily in healthy adults, assessing the number of bites, cycles per bite and per meal, and mastication speed, rate, and time. For swallowing, these devices have been applied to both healthy adults and individuals with dysphagia, focusing on detecting swallowing activities and differentiating them from other muscle activities. However, there is a gap in the development of devices that fully integrate the phases of ingestion, processing, and swallowing, with greater clinical support to improve monitoring and application in different health conditions.

Resumo

Objetivo: identificar e descrever dispositivos eletrônicos vestíveis usados para o monitoramento da mastigação e deglutição em adultos.

Métodos: a pesquisa foi realizada nos motores PubMed e MedLine via Ovid®, por dois pesquisadores independentes. Foram selecionados estudos primários utilizando o Rayyan®, com análise de títulos, resumos e textos completos. As informações extraídas seguiram um protocolo de estudo.

Revisão da Literatura: foram identificados 243 estudos, dos quais após a aplicação dos critérios de inclusão e exclusão, 25 foram selecionados para análise. Os dados extraídos incluíram informações sobre participantes, dispositivos, sensores, localização e análises realizadas.

Conclusões: os dispositivos vestíveis para monitoramento da mastigação foram utilizados principalmente em adultos saudáveis, nos quais se avaliou o número de mordidas, ciclos por mordida e por refeição, além da velocidade, taxa e tempo de mastigação. Para a deglutição, os dispositivos foram aplicados tanto em adultos saudáveis quanto em indivíduos com disfagia, com foco na detecção de atividades de deglutição e na diferenciação de outras atividades musculares. Contudo, há uma lacuna no desenvolvimento de dispositivos que integrem de forma completa as fases de ingestão, processamento e deglutição, com maior suporte clínico para melhorar o monitoramento e a aplicação em diferentes condições de saúde.
