Physicians seek a method to assess neuromuscular disease that is both non-invasive and quantifiable. Many patients do not tolerate standard current day assessment tools (such as needle electromyogram), and Electrical Impedance Myography (EIM) has the potential to serve as a non-invasive, quantifiable, diagnostic tool for neuromuscular disease. If successful, these devices will allow for improved ability to diagnose neuromuscular disease and to assess disease progression or remission, allowing for better care of individual patients as well as for use in clinical trials, where improved outcome measures for neuromuscular diseases is being sought.
