Sierra Summit EMG NCS EP NMUS for EDX electrodiagnostics

Electrodiagnostic Systems for EMG, Nerve Conduction, Evoked Potentials, and Neurodiagnostic Ultrasound

Cadwell started with the world’s first microprocessor-controlled EMG, and has since invested more than 40 years of research and development into our electrodiagnostic solutions. We launched Sierra Summit in 2013, and this device is now one of Cadwell’s most dynamic pieces of neurophysiology diagnostic equipment. 

Today, we are working in tandem with some of the world’s leading  neurology and PM&R physicians and teaching hospitals. We’re leading the charge in neurodiagnostic technology capabilities. In 2018, Cadwell became the first company to offer fully integrated ultrasound. In response to feature requests, new technology, broader learning, and new clinical practices, we have evolved the diagnostic capabilities and features of Sierra Summit.
