EMG Electromyography

See it how you want to

Custom views give you full control of displays, colors, tables, and test protocols. User-defined roles mean that you get your unique settings every time, even if one’s acquisition preferences are different than another’s review settings.


Total control over how it sounds

Audio is important in EMG, and we aced it. Our two HD-quality speakers are loud with instant signal processing. Use the Audio Equalizer to customize your audio so EMG activity sounds familiar.

Use it how you want to

Customize your workflow with user-defined studies and tests that can be adjusted on the fly.

Custom Reports

Several professional report templates are included with the Sierra Summit, however you have full control to modify or create your own report templates. Ultrasound images and measurements can also be included.

Anatomy View

Anatomical images illustrating results can be included within the report to better communicate neurodiagnostic findings.

EMR integration and Data Management

Reports can be automatically sent to the patient’s EMR as embedded data or as an attachment when using CadLink with HL7. Reports can also be emailed, printed, or saved locally or to a remote server. Multiple formats are available including PDF, .DOCX, and .RTF.
