Dispositivo wearable para avaliação de tremores com perspectiva de uso em indivíduos com Parkinson

Abstract

Parkinson's Disease (PD) is a chronic neurodegenerative disorder that affects movement, characterized by tremors, rigidity, slowness of movement, and issues with balance and posture. With increasing prevalence with age, PD affects about 7 million people worldwide. The objective of the study was to develop a wearable device for monitoring tremors in PD patients, establishing an innovative tool to assess disease progression and optimize treatment methods. The methodology was divided into three main stages: the electronic part, the application, and the bracelet. In the first stage, a systematic review on PD and wearable devices was conducted. Subsequently, the electronic part was developed using an accelerometer, a gyroscope, and the ESP32 microcontroller, tested in software such as Multisim and Wokwi. The sleeve modeling was done using a wrist specification glove and the components were attached to a custom PCB board. The software simulation and physical assembly of the electronic components showed that the device is capable of capturing and processing tremors at different levels effectively. The application design was designed to facilitate patient integration via Wi-Fi.Tests demonstrated that the device is effective in detecting and quantifying tremors of different intensities, providing important data for monitoring disease progression and adjusting treatments. The developed interface made the device more accessible and intuitive, facilitating remote provisioning for healthcare professionals. Analysis of tremor frequency data (in Hz) makes it possible to assess the intensity and regularity of symptoms. During development, limitations arose in the stages of the electronics, external design and device interface. These limitations were overcome by applying the technical knowledge acquired throughout the course, providing a solid basis for solving the project's challenges
