Sierra Summit proves we know electromyography

John Cadwell, MD, BSEE, built his first EMG machine in his Seattle basement during his medical school residency in 1977. His goal was to create an EMG machine that was simple to learn and easy to use.

The Sierra Summit, first released in 2013, is the brainchild of 40 years of EMG research and development at Cadwell. We have responded to feature requests, new technology, and broader learning to bring you one of our most dynamic pieces of neurophysiology diagnostic equipment. In 2018, Cadwell became the first EMG company to offer a fully integrated ultrasound.

Today, Cadwell is working in tandem with some of the world’s leading physicians and teaching hospitals. We’re leading the charge in neurodiagnostic technology capabilities in EMG, nerve conduction, evoked potentials, ultrasound, and chemodenervation.
