Study suggests new approach for evaluating muscle coordination, fatigue

Chiba [Japan], January 4 (ANI): Surface electromyography (sEMG) is a conventional technique for measuring muscle electrical activity during exercise..

The first uses a pair of electrodes (metals that transmit electricity through non-metals) to record from a specific muscle, whereas the second uses a grid of electrodes placed in a tiny rectangular pattern to assess the potential distribution of intra-muscular activity..

In a new study published in the Journal of Physiological Anthropology on 27 October 2023, Professor Yoshihiro Shimomura of the Design Research Institute, Chiba University, along with a team of researchers, demonstrated the use of bulls-eye electrodes to evaluate the activity of multiple muscles at the same time and investigated its ability to assess fatigue and develop visuals of muscle coordination during a grasping task..

Thus, the study forms a base for further development of a multichannel sEMG system to increase the scope of measuring muscle activity..

Although our bulls-eye electrode system has some limitations such as electric gain, it is a robust system that illustrates the muscle activity due to fatigue, elaborates Dr. Dr. Shimomura concludes, Having access to an electromyogram can aid in the treatment of muscle disorders of people working in urban lifestyles and improve the health of elderly people..
