April, 2014    Diagnostic accuracy of microEEG®: A miniature, wireless EEG device: The results of a prospective clinical trial of microEEG® to measure its sensitivity and specificity compared to a “reference” EEG machine were published in the journal of Epilepsy and Behavior (link to full paper). The EEG recordings were acquired from Emergency Department (ED) patients with AMS, a population where the advantages of microEEG® are particularly valuable. Using the unblinded interpretation (abnormal or normal) of EEGs recorded from the reference system as a gold standard, the measured sensitivity and specificity of EEGs obtained from the microEEG® system did not differ significantly in either measurement condition including the use of unconventional electrodes with microEEG®. Thus, the diagnostic accuracy of microEEG® is comparable to that of the reference system in this clinical ED setting. (Link to Presentation)
March, 2014    Effect of microEEG® on Clinical Management and Outcomes of Emergency Department Patients With Altered Mental Status: A randomized controlled (RCT). The RCT results of the work up of Emergency Department (ED)/Altered Mental Status (AMS)patients with and without microEEG® have been published in Academic Emergency Medicine Journal (link to full paper). A total of 149 patients were enrolled (76 control and 73 receiving microEEG®). Using microEEG® was associated with change in diagnostic work-up in 49% (95% CI = 38% to 60%) of cases and therapeutic plan in 42% (95% CI = 31% to 53%) of cases immediately after the release of the EEG results. Electroencephalograms (EEGs) obtained by microEEG® can affect diagnostic and therapeutic management of AMS patients in the ED. These findings paired with the high incidence of electroencephalographic abnormalities in AMS patients, further support the need to incorporate EEG in the work-up of these patients in the ED.

December, 2013    microEEG® use by bedside Neonatal ICU (NICU) staff: Few NICUs are equipped with EEG machines or staffed with specialized technologists who can properly apply EEG electrodes and provide a technically adequate study. The microEEG® system provided high quality continuous EEG recordings in the NICU performed by bedside staff. This approach was presented at the American Epilepsy Society Annual Meeting- December 2013- Washington D.C. (Link to Presentation)

About BSG
Bio-Signal Group’s (BSG) mission is to enable functional brain monitoring anywhere at any time, for everyone. Our initial solution is the microEEG® System, a small, wireless, easy-to-use brain monitoring system designed specifically for use in the Emergency Department.

BSG was founded in 2002 by Dr. André Fenton to commercialize a proprietary digital telemetry (DT) technology. Since its founding, BSG has worked on developing new applications for DT, and in recognition of the strength of its technology and team, has been awarded multiple competitive NIH grants for developing DT technology for these applications. These include "Wireless Recording of Wideband Neuronal Activity in Freely Moving Humans". . . More About BSG
