EEG (electroencephalograph) and EMG (electromyograph) systems are functional diagnostic platforms that record bioelectric activity from the brain and from skeletal muscle/peripheral nerves, respectively. Buyers typically include neurology departments, epilepsy monitoring units (EMUs), ICUs/EDs, sleep labs, physiatry/PM&R clinics, neuromuscular and pain practices, and ASCs offering intraoperative neuromonitoring (IOM). Most modern systems are modular — the same amplifier platform may run routine EEG, ambulatory/LTM, EMG/NCS, evoked potentials (EP), and IOM with software licenses determining capability.
