Electromyography (EMG) Analysis add-on for OpenSignals (r)evolution

plux biosignals, OpenSignals, Electromyography (EMG) Analysis add-on

This add-on is designed to extract useful statistical temporal and spectral information from electromyography data acquired with the Electromyography (EMG) sensor. Its own automatic onset detection algorithm is designed to detect muscle activations in the EMG signal, allowing the user to select and derive activation-specific parameters for further analysis of the EMG signal.

The onset detection algorithm can be fine-tuned for application-specific muscle activation detection by defining the frequency ranges of interest using the available low pass, high pass, and band pass filters. This add-on can also be used for muscle activation order analysis and to conduct a Maximum Voluntary Contraction-dependent statistical analysis.
