Literature review of stroke assessment for upper-extremity physical function via EEG, EMG, kinematic, and kinetic measurements and their reliability

Table 6 Summary of metrics from EEG-EMG coherence and main findings related to motor function

Metric	Stage	Correlation with clinical measures/findings [reference]
Beta, Gamma CMC	Chronic	Flexion synergy [93], FMA [37]
Beta CMC	Sub-acute	Function recovery, FMA-UE [141]
Gamma interhemispheric disparity	Chronic	Compensation of healthy limb [145]
CMC frequency peak	Acute, chronic	Characterization of CMC from stage to stage [146], non-significant differences among stages [112], Beta peaks related to co-contraction [149]
CMC topographical patterns	Acute, sub-acute	FMA, FMA-UE [144], level of impairment [142]
