Table 2.
Intra class correlation coefficient (ICC) of EEG absolute power in seated (sit) and walking (wlk) conditions for each EEG frequency band.
| Intra-class correlation coefficient (ICC) – Absolute power | ||||
|---|---|---|---|---|
| Theta | Alpha | Beta | Gamma | |
| Seated | ||||
| BSM | 0.63 | 0.99 | 0.99 | 0.49 |
| Cwet | 0.76 | 0.84 | 0.93 | 0.68 |
| Cdry | 0.47 | 0.84 | 0.86 | 0.82 |
| Walking | ||||
| BSM | 0.96 | 0.98 | 0.98 | 0.98 |
| Cwet | 0.93 | 0.99 | 0.99 | 0.95 |
Data was recorded from three EEG systems (Biosemi: BSM, Cognionics wet (Cwet) and Cognionics dry (Cdry)). No data from Cdry was included in the walking condition since the 75 μV amplitude threshold removed all epochs for this system and condition.
