Fibromyalgia Patients Had Normal Distraction Related Pain Inhibition but Cognitive Impairment Reflected in Caudate Nucleus and Hippocampus during the Stroop Color Word Test
Figure 2
Average normalized PPTs ± SEM during a) congruent and b) incongruent SCWT in FM patients and HC.
PPTs increased in both groups alike during congruent as well as incongruent SCWT. There were no statistically significant differences between congruent and incongruent SCWT regarding the modulation of PPTs. * = p<0.05, ** = p<0.01, *** = p<0.001. The normalization was performed as follows: each PPT value was divided with the individual’s first PPT at baseline and the curves were adjusted (by adding a coefficient) so that the baseline value always corresponded to 1.
