Desenvolvimento de um sistema para aquisição de biossinais utilizando um cicloergômetro para membros superiores

Abstract

By combining the execution of controlled physical activities and the collection of biological data, it is possible to obtain information that can be used to diagnose diseases and prescribe treatments. Physical activity for people who have difficulties or are unable to move is very restricted, which is why the cycle ergometer for upper limbs has proven to be important for this group, mainly for physiotherapeutic purposes. In physiotherapy, the electromyography technique is a very useful tool for diagnosing musculoskeletal disorders and determining fatigue and muscle activation. In view of this, this work aims to develop an experimental prototype with the purpose of integrating a cycle ergometer for upper limbs with sensors capable of collecting biological information, such as myographic signal and heart rate, as well as rotations per minute and execution time. For this, platforms for acquiring myographic and heart rate signals were used. A microcontrolled platform was responsible for collecting, processing and storing signals from the sensors. The tests carried out demonstrated the possibility of using this system to determine muscle activation and fatigue. Using this data, health professionals will be able to evaluate and estimate diagnoses related to their area of study. [resumo fornecido pelo autor]
