About Us Banner

Founded in 2002, Impulse Monitoring, Inc. (IMI) was among the first companies to provide onsite and Web-based monitoring of the neurological systems of patients undergoing spinal and brain-related surgeries. Known as intraoperative neurophysiological monitoring, or IONM, it is a technique that changed the standards of care for these patients by reducing the risk of permanent neurological damage.

At the time IMI was founded, the prevailing model for neuromonitoring was technologist-based without physician oversight. Any contracting with physicians was to provide post-surgery review of neuromonitoring records. However, this approach provided no clinical benefit to the surgeon or the patient. It was this lack of physician oversight that drove IMI's founders to offer an IONM service that would deliver tangible benefits during surgery by providing an onsite neurophysiologist who is supported by real-time physician oversight.

Today, IMI employs certified neurophysiologists and partners with highly experienced physicians who use state-of-the-art-monitoring equipment to provide surgeons, hospitals and medical centers with a complete outsourced IONM solution. IMI neurophysiologists located in the operating room work as a team with supervising physicians who oversee the interpretation of the neurophysiological data gathered during surgery via broadband, real-time transmission of signals and instant communication. Additional remote technical and senior expertise is available as needed, as well as access to a broad range of on-line knowledge resources.

Over the years, we have established ourselves among the nation's leading IONM companies, serving more than 200 leading hospitals and over 800 surgeons in 24 states and the District of Columbia. And we continue to grow through recent acquisitions that have brought our brand of IONM to new areas of the country and through our recent acquisition by NuVasive, Inc. (Nasdaq: “NUVA”).


“This group has effectively incorporated our outstanding long-term neuromonitoring technicians into an improved backup system coupled with increased breadth of coverage to provide a nearly ideal system of neuromonitoring service.”
