Questions and Answers

What is the purpose of the Human Behavior Assessment System based on EMG signals?

To record the electrical activities of muscle tissue
To insert a needle with an electrode into the muscles for recording Intramuscular EMG
To apply electrodes on the skin for recording surface EMG
To measure the electrical behavior generated by neuromuscular activities (correct)

What does the Electromyogram (EMG) signal measure?

The insertion of a needle with an electrode into the muscles
The electrical activities of muscle tissue
The application of electrodes on the skin
The electrical behavior generated by neuromuscular activities (correct)

What are the two general methods of recording the electrical activities of muscle tissue?

Using EMG signals and measuring neuromuscular activities
Recording the signal referring to surface EMG and recording Intramuscular EMG
Applying electrodes on the skin and inserting a needle with an electrode into the muscles (correct)
Acquiring biomedical signals and measuring physical variables of interest
