What Is EMG (Electromyography) ?
Electromyography (EMG) measures muscle response or electrical activity in response to a nerve’s stimulation of the muscle. The test is used to help detect neuromuscular abnormalities.

How does it work?

Whenever a muscle contracts, a burst of electric activity is generated which propagates through adjacent tissue and bone and can be recorded from neighboring skin areas.

Acquire the raw EEG signal from the nerves via contact electrodes
Process the raw data to remove noise and enhance relevant signals.
Algorithm, we calculate the ‘Power Spectral Density’ ratio to classify and assign the set of features extracted from the signals
The processed signals are output as digital messages for the computer and/or interactive application

Why EMG(Electromyography)?

An EMG signal is the train of Motor Unit Action Potential (MUAP) showing the muscle response to neural stimulation.
