To evaluate a novel stereoelectroencephalography (sEEG) headband designed to reduce artifacts during sEEG recordings in patients with drug-resistant epilepsy.

sEEG is a diagnostic method used to localize seizure foci in patients with drug-resistant epilepsy when non-invasive approaches fail. A challenge during recording is motion and electrical artifacts, which can obscure true brain activity. These artifacts arise from patient movement, shifting electrode leads, and external electrical interference. Traditionally the leads are bundled in a tail behind the patient’s head, which is prone to motion artifacts. Over time, degradation of electrodes can also introduce noise into the recordings. 

This novel sEEG headband was utilized at our institution over the past four years. In contrast to bundling leads in a tail, the headband immobilizes the leads by threading them through sleeves, securing them to the skull. This method prevents motion-induced artifact and reduces tension on the leads. The headband was applied post implantation, and recordings from patients were compared to those using traditional electrode bundling. Recordings were analyzed for artifact frequency, type, and overall signal clarity.

The use of the sEEG headband led to a reduction in artifacts, including those caused by motion, external interference, and electrode degradation. Patients reported increased comfort due to the elimination of the electrode tail, and less maintenance was required. sEEG recordings had improved signal quality, facilitating better localization of seizure activity. Overall, the use of the headband across patients reduced artifacts while incurring minimal additional costs and causing no adverse effects.

By securing electrode leads on the skull, the sEEG headband minimizes interference, resulting in more reliable recordings for seizure localization. Beyond enhancing accuracy, the headband improves patient comfort and streamlines workflow by reducing maintenance. Its simplicity, cost-effectiveness, and efficacy offer value to both patients and healthcare providers.
