Table 3 Features that discriminate Pre-tremor condition from Tremor and Control conditions (multiple comparisons corrected p-value < 0.01)
From: Parkinson’s disease tremor prediction using EEG data analysis-A preliminary and feasibility study
Condition | Feature | EEG frequency band | EEG channel | Description |
|---|---|---|---|---|
Off-medication, eyes-closed | Form factor | Delta | F7, FC5, FC1, PZ, O1, P4, P8, CP6, CP2, C4, CP3, P1, P5, PO3, POZ, PO8, P2, CP4, TP8, FT8 | The feature value for pre-tremor is significantly higher compared with tremor and control conditions (p < 0.01) in 3-s window. |
Peak frequency | Gamma | FC6 | ||
ON-medication, eyes-closed | Form factor | Delta | F4, P4 | Significantly larger value for 3-s pre-tremor segment compared with the same duration of tremor and control conditions (p < 0.01). |
