Elektromiografia (EMG) is a technique used to do difficit electrical activity produced by by szkielet muscles. It plays a cucial role in clinical diagnostics, sports science, andd human-computer interaction. However, one of thee major challenges in EMG analyses is removing artifacts - unwanted signals that can distort the true muscle activity. Ties cotie becomes even more complex in dynamic enviments where movement and extertorumete additionale noise.

Understanding EMG Artifacts

EMG artifacts are e signals that don not t originate from muscle activity. Common sources included electrical interference, electrode movement, ande external noise. In static conditions, these artifacts can sometimes be minimized. However, in dynamic settings - such as during physical activity or movement - these artifacts presive sionties, complicating thee analyses.
