The surface electrode for EEG was cleared by the FDA via the 510(k) pathway on August 13, 2002. It is manufactured by The Electrode Store and classified as a Class 2 device.

What It Is

The surface electrode for EEG is a device used to record electrical activity from the brain's surface. It is primarily used in clinical settings to diagnose and monitor neurological conditions such as epilepsy.

FDA-Cleared Indications

  • Recording electrical activity from the brain through scalp electrodes during an electroencephalogram (EEG).

Clinical Applications

  • Routine or prolonged EEG recording in clinical settings
  • Monitoring brain-wave activity during neurological evaluation
  • Use as part of EEG-based assessment when directed by a qualified clinician

Reported off-label uses

  • Research recording of high-frequency EEG oscillations as potential biomarkers in epilepsy
  • Research and clinical monitoring applications involving quantitative EEG analysis

Off-label use: these uses are reported in practice or the literature but are not part of the FDA-cleared indications. Physicians may use a cleared device off-label based on their medical judgment; the manufacturer may not promote off-label uses.

Evidence Summary

The literature includes 15 studies, comprising randomized controlled trials, prospective, and retrospective studies, published between 2021 and 2024. These studies explore various aspects of electrode design and its impact on EEG measurements.

Reported Outcomes

Published studies report that electrode surface area significantly impacts the measurement of high-frequency oscillations in EEG, which are crucial for assessing surgical outcomes in epilepsy. The design and placement of electrodes also affect signal quality and diagnostic accuracy.

Safety Profile

Reported complications include potential skin irritation at the electrode site and signal interference due to improper electrode placement. No severe adverse events have been documented in the reviewed studies.

Evidence Limitations

Evidence gaps include a lack of large-scale studies directly comparing different electrode designs. Further research is needed to standardize electrode placement and improve signal accuracy across diverse patient populations.

Practical Considerations

  • The electrode must be applied to the scalp with appropriate conductive material and securely connected to compatible EEG recording equipment.
  • Skin preparation may be needed to reduce impedance and improve signal quality; the skin should be checked for irritation after removal.
  • This is an external recording electrode and does not penetrate the skull or brain.
  • MRI compatibility depends on the specific electrode construction, lead wires, and connected EEG system; verify labeling before MRI exposure.
  • Avoid use on damaged or infected scalp skin unless specifically directed by a clinician.
