Table 2 Comparison between the trigeminal and the peripheral pain measurement in migraine subjects
Trigeminal | Peripheral | Significance | |
|---|---|---|---|
Sensory threshold (mA) | 1.0 ± 0.3 | 1.1 ± 0.6 | p = 0.391 |
Pain threshold (mA) | 3.3 ± 2.0 | 6.7 ± 4.8 | p < 0.001 |
Threefold pain threshold stimulation (VAS in mm) | 4.8 ± 1.6 | 2.9 ± 1.8 | p < 0.001 |
1. Train with 1.5-fold pain threshold stimulation (VAS in mm) | 4.1 ± 1.4 | 2.8 ± 1.8 | p = 0.002 |
2. Train with 1.5-fold pain threshold stimulation (VAS in mm) | 4.3 ± 1.7 | 3.0 ± 1.6 | p < 0.001 |
Difference between 2. train and 1. train | 0.2 ± 1.3 | 0.2 ± 1.0 | p = 0.641 |
