Feasibility and Usability of Home-Based Visual Evoked Potential Electroencephalogram in Neurological Telemonitoring...

Background: Telemedicine offers promising tools for migraine care and research. A home-based visual evoked potential electroencephalogram (VEP-EEG) system was developed to help predict migraine attacks. Objective: To evaluate the usability and user-friendliness of a home-based VEP-EEG setup for research purposes. Methods: One group of 20 participants evaluated the first VEP-EEG setup. Another group of 20 participants evaluated the second setup. Setup 2 was modified based on feedback from group 1. Each participant completed 2 measurement days on separate occasions. Usability was assessed using the System Usability Scale (SUS), task completion time, number of successfully connected electrodes, and overall user experience. Results: Both setups scored high on usability: Setup 1 had a median SUS of 91.2 [interquartile range 86.2 to 95.0], setup 2 scored 81.2 [70.6 to 90.6]. Group 1 showed a significant reduction in task time between sessions (-3.3 min, P < 0.001); no significant change was observed for group 2. Successful electrode connection rates were similar (median 6/7). Overall experience was rated highly by participants (median 4/5). Conclusion: Home-based VEP-EEG telemonitoring is feasible and user-friendly. Significance: These results support its use in remote research and broader applications in studying paroxysmal brain disorders; however, further studies are needed to validate EEG signal quality.
