An electromyogram (EMG) consists of examining the electrical activity of a muscle at rest and in contraction under the action of a spontaneous command from the patient. Our range of EMG & ENMG devices includes 2 to 8 acquisition channels. They also have additional functionalities such as : motor unit number estimation (MUNE), somatosensory evoked potentials (SEP), visual evoked potentials (VEP), auditory evoked potentials (AEP), vestibular myogenic potentials (VEMP), cognitive evoked potentials (CEP), transcranial magnetic stimulation (TMS), intraoperative monitoring (IOM), cardiac rhythm variability (HRV), objective audiometry (OA), electroretinography (ERG), electrooculography (EOG).
