Electro-Luminescent System for Detection and Classification of Muscle Movements
摘要
Electromyography (EMG) has long been the technique of choice for recording the electrical activity of muscles. An alternative method, the optical technique, which detects changes in muscle oxygenation levels, has not been widely employed despite its potential. In this study, we combined EMG with optical methods, such as infrared (IR) and red light (R), in an effort to develop an advanced system for recording muscle activity that will have applications in prosthetic control. The optical technique provides an additional layer of information, translating oxygenation changes into muscle activation data, giving us a more complete view of muscle dynamics. This complementary approach allows for better control and understanding of muscle activity, improving the accuracy and effectiveness of prosthetic devices. The study involved five subjects in an experimental protocol that consisted of a sequence of specific hand movements recorded by means of both EMG and optical methods. Recordings were taken at 3 points on the forearm to obtain 9 signals that corresponded to 3 channels: infrared (IR), red light (R), and EMG. Performance accuracy was 91.6.
