Overview

Systematic review and meta-analysis reveals increased resting-state theta power in patients with traumatic brain injury, highlighting altered neural oscillations across injury etiologies.

Key Points

Systematically review and quantify resting-state EEG spectral power alterations following traumatic brain injury and examine whether clinical and injury-related variables moderate these effects.
Followed PRISMA guidelines to identify case-control and longitudinal studies assessing resting-state EEG spectral power metrics after traumatic brain injury.
Identified 24 eligible studies comprising 1,236 participants (713 with traumatic brain injury and 523 controls), with 14 studies contributing 39 effect sizes to meta-regression models examining etiology, sex, age, time since injury, and injury severity.
Traumatic brain injury was associated with significantly increased theta power relative to controls (Hedges' g = 0.50, p = 0.03), alongside general patterns of slow-wave increases and fast-wave suppression.
Injury etiology and biological sex initially moderated theta power alterations (p = 0.03 for each), though neither effect remained statistically significant following false discovery rate correction.
