Table 3 Pre-treatment CNV data for migraine patients vs. healthy controls

From: Progressive muscle relaxation reduces migraine frequency and normalizes amplitudes of contingent negative variation (CNV)

  M migraine patients (n = 35) (SD) M healthy controls (n = 46) (SD) t-value (p)
iCNV amplitude (μV) −11.65 (5.65) −8.62 (4.37) −2.63 (0.006**)
oCNV amplitude (μV) −8.66 (2.65) −6.7 (2.51) −3.39 (<0.001***)
Habituation coefficient −0.05 (1.08) 0.13 (1.11) −0.72 (0.22)
