Sierra Summit® Electrodiagnostic Platform

Sierra Summit®

Scalable EMG • NCS • EP • NMUS in a Single, Rugged System

The Sierra Summit is Cadwell’s flagship neuro‑ and electro‑diagnostic workstation. From a compact 2‑channel portable to a 12‑channel cart‑based lab with integrated ultrasound, Summit adapts to every practice—delivering crystal‑clear signals, protocol‑aware workflow, and durability that stands up to years of daily testing.

Key Features
  • 1 – 12‑Channel Smart Amplifiers: Choice of 1–2 CH or 3–12 CH amplifiers with sophisticated filtering, very low noise, RF immunity, and fast artifact recovery. Channel count can be changed or remapped on‑the‑fly during acquisition—no reboot required.
  • StimTroller Plus™ Handheld Remote: Perform an entire NCS from the palm of your hand: intensity, pulse width, nerve & site selection, trace select, distance, and more—reducing chair‑time and cabling clutter.
  • Protocol‑Driven Sierra Software: Pre‑loaded EMG, NCS, EP and SFEMG+ protocols with live MUP, jitter, firing‑rate and interference‑pattern analysis. Combination strategies display motor, sensory, F‑wave and H‑reflex traces side‑by‑side; auto cursors, Hold‑Max and Improve buttons speed acquisition and interpretation.
  • Integrated Ultrasound (NMUS1® Option): Switch between ultrasound and electrodiagnostics with one button; include images and measurements directly in EMG reports.
  • Durable, Service‑Friendly Hardware: Machined‑aluminium knobs, raised buttons and electrode connectors rated for 100 k+ actuations; industrial locking cables and internal test fixtures ensure years of reliable use.
  • Portable or Cart‑Based Configurations: Laptop or mini‑PC versions travel easily for outreach clinics; ergonomic EMG and Fuzion carts offer height‑adjustable, all‑in‑one lab setups with optional NMUS and video.

Why Choose Sierra Summit?
  • : Scales with your practice—start with two channels for routine studies, expand to twelve for comprehensive EP or research without replacing hardware.
  • : Workflow that thinks like you do—protocol‑specific keys, smart software, and StimTroller Plus™ keep tests fast, consistent and accurate.
  • : Integrated multimodality—add ultrasound, trigger devices, cameras or even EEG/IOM to the same cart for true one‑station neurodiagnostics.
  • : Built to last—industrial‑grade components, self‑test fixtures and electrode continuity checks reduce downtime and service costs.
  • : Future‑ready analytics—API access, CSV/export, and compatibility with Cadwell’s AI‑assisted Synopsis® trends position your lab for upcoming data‑driven care.

Sierra Summit equips neurophysiology teams with the signal quality, versatility and rugged reliability needed to diagnose nerve and muscle disorders confidently—today and as technology evolves.
