Sierra Summit EMG NCS EP NMUS for EDX electrodiagnostics

Sierra Summit is designed for the electromyographer who prioritizes reliability and efficiency for their EMG, NCS, EP, and Ultrasound needs

Cadwell offers cutting-edge neurodiagnostics with forward-thinking hardware and innovative software

The Sierra Summit is the brainchild of 40 years of research and development at Cadwell. We have responded to feature requests, new electrodiagnostic (EDX) 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 fully integrated ultrasound.

Today, Cadwell is working in tandem with some of the world’s leading  EDX physicians and teaching hospitals. We’re leading the charge in neurodiagnostic technology capabilities in EMGnerve conductionevoked potentialsultrasound, and chemodenervation. The Sierra Summit is a powerful tool for all of your neurodiagnostic monitoring.

Cadwell uses the highest quality components to deliver durable and reliable neurodiagnostics

  • Test fixtures and electrode tester for instant hardware diagnostics
  • Machined aluminum knobs and raised buttons rated for 100k+ uses

    Cadwell is dedicated to proactively contributing toward the advancement and promotion of Neuromuscular and Diagnostic Ultrasound

    We believe that by providing a fully integrated EDX/US diagnostic solution, and by driving the development of dedicated ultrasound-focused features, we will be able to help you help others even more efficiently in the future.

    An emerging diagnostic subspecialty, ultrasound is recognized as a complementary practice for neurodiagnostic testing in neurology and physical medicine and rehabilitation. High resolution US can study peripheral nerves, sensitively observe muscle disease, guide local anesthetic administration for nerve blocks, and enhance nerve localization. Ultrasound improves safety margins for injection needle procedures, EMG needle placement, and direct needle stimulation of deep nerves.

    Detect, confirm, and monitor problems with nervous system function with Sierra Summit Evoked Potentials

    Both Summit amplifiers can be configured for flexible, efficient, and smart somatosensory (SSEP), visual (VEP) and auditory (AEP) evoked potential studies. A variety of stimulators are available, as well as trigger inputs to connect to peripheral devices. Protocol-specific evoked potential functions on the Summit Base Unit are integrated into the software for ease of use.
