- Most common artifact
- Frequency 20 to 100 Hz
- High amplitude
- Most common muscles: frontalis and temporalis muscles (eg, tightening of the jaw muscles)
- Muscle artifacts represent motor unit potentials as typically observed on needle electrode examination during electromyogram
- A high frequency filter can reduce this artifact
