Test-retest of wireless dry-electrode EEG during a dynamic psychomotor virtual reality task.

The study used an immersive VR boxing focus ball protocol as the dynamic psychomotor task, whereby EEG was collected pre, post, and during an immersive VR exergame (VRex) 11 minute task-active interval.

Baseline Folder: Test-Retest EEG data collected during resting EEG pre (B1 = test, B3 = retest) and post (B2 = test, B4 = retest) VRex.

Test Folder: Task active intervals involved a 3x3-minute focus ball protocol with a one-min rest in between each subsequent round (T1= Test and T2 = Retest).

EEG: A wireless dry-electrode 7-sensor DSI-7 EEG system (DSI-7 SN:2449, Wearable Sensing, LLC, USA) was used. Data was collected at a sampling rate of 300 Hz with the electrode setup (F3, F4, C3, C4, Pz, P3, P4) abiding by the 10-20 International System. Data were pre-filtered by the DSI-7 system, which involved pass of a high-pass filter of 1 Hz and a low-pass filter of 50 Hz. Upon collection, data was referenced against an electrode located on electrode site LE.
