A review of motion related EEG artifact removal techniques

The traditional EEG (electroencephalograph) system requires the subject to stay still when acquiring bio-signals. There have been mobile EEG units, for instance ambulatory electroencephalography (AEEG), a portable device designed for recording ictal events or interictal epileptiform discharge. However, these were never intended for motion related EEG recordings. Such techniques constrain motion related brain potential tests. A number of papers have considered this issue and as a result a new research area was established. This paper is a review on the different aspects of this problem, such as algorithms and hardware design, for the reduction of motion related EEG artifacts. Finally, this paper recommends several proper strategies on EEG artifact reduction.
