Metric | Stage | Correlation with clinical measures/findings [references] |
---|---|---|
Global Beta power Global Alpha power | Acute | First noticeable electrical changes during stroke [58], 105-day FIM FAM [53], 12-months NIHSS [96] |
Delta power, Theta power | Sub-Acute | |
Delta-Alpha Ratio (DAR) Delta-Theta Ratio (DTR) (Delta + Theta)/(Alpha + Beta) Ratio (DTABR) | Sub-Acute | cognitive deficit [53], 90-days MoCA [54], 6-months mRS [105], 12 months NIHSS[96], 6-months FIM FAM [97], NIHSS evolution 3 weeks to 6-months [120] |
Brain Symmetry Index (BSI) Pairwise derived brain symmetry index (pdBSI) | Sub-Acute | |
Global Delta | Chronic | motor therapy gains [122] |
Delta-Alpha Ratio (DAR) Power Ratio Index (PRI) | Chronic | FMA evolution [99] No relation with FM-UE [125] |
Brain Symmetry Index (BSI) | Chronic | FM-UE [125], directional BSI delta band correlated with FM-UE improvement and NIHSS evolution [120] |
