About Us
Our Mission
Emerge Diagnostics provides global medical services to assist in the diagnosis and treatment of soft tissue injuries, helping people get back to work and life faster.
The company's Electrodiagnostic Functional Assessment (EFA) programs have been used by dozens of the world's largest employers over the past 10 years, enabling dramatically improved outcomes for workplace injuries. Recent enhancements to the program make it possible to deliver the full extent of testing and ongoing monitoring via objective telemedicine evaluations.
Our EFA technology combines five American Medical Association-accepted diagnostic tests into one comprehensive, objective, and reliable test to help patients, employers, and healthcare providers get accurate results and get better faster.
