Evoked Potential Clinical Solutions

Use Sierra Summit® Evoked Potentials (EP) tests to help evaluate the integrity and function of the central nervous system and detect disease or dysfunction. Sierra® software offers a full suite of pre-configured VEP, AEP, SSEP, and MEP protocols for capturing quality EP signals and comprehensively assessing patients.

Sierra Summit EP Testing

Sierra Summit for Evoked Potential (EP) testing

  • With the Sierra Summit, you can scale from 1-12 channels and easily add or re-montage channels during acquisition
  • A variety of stimulators are available, as well as trigger inputs to connect to peripheral devices
  • The inexpensive Remote Input Box helps protect amplifiers, access tight spaces, and ensure strong electrode connections during EP studies

Smart EPs

  • Use advanced stimulation and acquisition modes
  • Take advantage of advanced post processing: Compare, combine, average, grand average, smooth, and invert trials
  • Use custom cursors and calculations: Latency, amplitude, inter-latency, inter-amplitude, percentages, ratios, and side-by-side comparisons
  • Live Test Edit: Easily adjust parameters, protocols and channel count during acquisition

Efficient EPs

  • Auto Cursors: Auto place cursors on any trial with the click of a button
  • Custom Protocols: Preset protocols reduce testing time and ensure consistency
  • Custom Reports: Create unique report templates for protocols
  • Auto-Findings: Automatically generate findings paragraphs based on reference values
Median SEP 4-channel

With Sierra Summit Evoked Potentials, you can:

  • Detect, confirm, and monitor problems with nervous system function
  • Assess hearing, sight, and brain activity
  • Detect lesions or tumors
  • Identify nerve damage
  • Complement your other tests, including EMG and MRI scans

Sierra Summit includes four trigger-in and four trigger-out TTL ports for interfacing with external devices and applications, including magnetic stimulators, flash stimulators, research amplifiers, and a variety of other third-party devices. You can customize your Sierra Summit hardware and Sierra software to fit the specific needs of every patient in your practice.

Sierra software offers the following Evoked Potential protocols:


SEP Protocols: SEP, Dermatomal SEP, Interleave SEP, Trigger-In and Trigger-Out.


VEP Protocols: Pattern VEP, Flash, ERG, Goggle, Trigger-In and Trigger-Out (ERG requires an external flash stimulator).


AEP, MLR, VEMP, ECochG, P300 with Headphone, Bone Transducer and Insert Earphones.

Sierra software EP protocols can help diagnose and track these neurodegenerative disorders:

  • Parkinson’s disease
  • Alzheimer’s disease
  • Cortical or peripheral impaired pain perception
  • Multiple sclerosis and other demyelinating disorders
