SPEAC System

The SPEAC surface electromyography (sEMG) monitor is worn on one arm at the belly of the biceps muscle. This lightweight, non-invasive monitor continuously senses and monitors sEMG signals which reflect the activity in the motor cortices of the brain. The sEMG monitor takes 1,000 sEMG samples every second. Brain Sentinel’s SparkSenseTM diagnostic algorithm analyzes those samples in real time, looking for tonic-clonic muscle activity that is indicative of a GTC seizure. Once recorded, the data are sent to and stored securely by Brain Sentinel where we begin analyzing all the hours of data. At the end of a monitoring period, the ordering physician will receive a summary report to help with clinical decisions.

Mike Girouard, our President and CEO, and Dr. José E. Cavazos, M.D., PhD, a renowned Epileptologist, founded Brain Sentinel in 2009. The team searched for a seizure signal to measure and monitor. After years of testing and developing, Brain Sentinel created a System that harness sEMG, a biomarker for seizure activity. In February 2017, the SPEAC® System became the first FDA-cleared, non-EEG, physiological, signal-based system for seizure monitoring.
