The neuromuscular system is a complex multiscale and multiphysic System of Systems (SoS) that is responsible in conveying the neural information into a generated force that will initiate motion of the musculoskeletal system. Classically, electromyography technique is related to the use of few electrodes with no standardized position in clinical applications. Usually, in clinical routine, the surface EMG (sEMG) amplitude is assessed using classical descriptors like ARV and RMS, but with possible meaningless interpretation due to electrode position variability.
A recent technique, High Density surface electromyography (HD-sEMG), overcomes this limitation by providing spatial activation maps or images of the muscle contraction using a surface electrode grid. It opens the door to more sophisticated signal analysis that takes into account this spatial representation and increases to robustness of the obtained results. Through the webinar, recent works will be presented to illustrate the poossibilities of this technique, using TMSi devices (REFA System), for deeper investigation of the neuromuscular system.
