Abstract

Rapid eye movement (REM) sleep without atonia (RWA) is the polysomnographic hallmark of REM Sleep Behavior Disorder (RBD). The state-of-the-art methods to score RWA are visual-based. Recent international guidelines recommended the Sleep Innsbruck Barcelona (SINBAR) method for scoring RWA in 3-s mini-epochs. This method calls for scoring phasic EMG activity in the flexor digitorum superficialis (FDS) and “any” (i.e., tonic and/or phasic) EMG activity in the mentalis muscle. A semi-automatic algorithm scoring RWA according to this method is currently available in a commercial polysomnographic system (BrainRT, OSG, Belgium), however it still requires manual removal of EMG artifacts from expert scorers. This work proposes a novel method that, based on morphological aspects of EMG activity and machine learning (ML), discriminates activity from artifacts in the evaluation of RWA, thus allowing automatization for artifact correction.
