Sleep disturbances occur in 30-70% of individuals following traumatic brain injury (TBI).1 When chronic sleep disruption occurs it may exacerbate other symptoms, impair recovery and lead to cognitive decline.2 As progression and/or treatment of sleep disturbances can indicate lessening or worsening secondary affects, many researchers incorporate the assessment of sleep into their studies.
A common method of incorporating sleep assessment involves monitoring both EEG and EMG via either implantable telemetry or a tethered hardwired system. EEG is used to identify the type of sleep that is occurring and EMG is used to identify the presence or absence of rapid eye movement (REM).3,4 Some researchers also use skeletal muscle EMG, activity measurements, and/or video to differentiate between REM sleep and wakefulness.
DSI’s NeuroScore software automatically scores the type of sleep during each epoch based on EEG, EMG, and activity data. Stages scored include REM sleep (paradoxical), slow wave sleep (with option to distinguish between SWS-1 and SWS-2), wake, and active wake.
