HD-sEMG acquisitions during highly dynamic tasks

It is in highly dynamic contractions that MEACS (Modular Electrophysiological Acquisition System) meets its true potential. Be it to assess the excitation of the many, abutting forearm muscles while pianists perform at rates over 10 keystrokes per second, or to study the mechanisms of injury protection in the lower limb during 80 m, on-field sprints: MEACS has unprecedented ability in rejecting movement artefacts, providing High-Density sEMG with unmatched quality.

In addition to featuring maximal suppression of movement artefacts, setup time and encumbrance are both drastically reduced when compared to traditional high-density systems. MEACS bridges the gap between laboratory testing and real-world contexts in which it is required to perform HD-sEMG and EEG evaluations. MEACS has been successfully used during piano playing [1], on-field sprint [2], and sport climbing [3].
