Most established journals require a submitted article of a study to went through IRB process if that study involve human. It is a compulsary process especially if the study involve experimental on human body such as the use of EMG and EEG. The use of IRB is to ensure the experimental procedure is safe to the human subjects and is ethical.
Therefore, I would suggest to have an internal IRB so that the researchers in UTM do not need to submit an external one which normally took a very long time.
