2 Fig. 1 Evaluation for mechanism of chronic low back pain using fMRI. a) Blood oxygenation level-dependent (BOLD) signals (orange area) due to pain stimulation are apparent. b, c) Time-course analyses of BOLD signals in the NAc compared with low back pain patients. BOLD amplitude showing NAc activation was significantly smaller in psychiatric problem patients (b) than in non-psychiatric problem patients (c).

3 Fig. 2 Default mode network by resting-state fMRI. Analysis of BOLD signals in the resting state. In the default mode network, positive BOLD activation (orange area) is present in the resting state, while BOLD signal is deactivated (blue area) according to task.

4 Fig. 3 Cerebral blood flow scintigraphy. a) Before treatment. Cerebral blood flow is reduced in each slice. b) Two months after treatment. Red color has spread in all slices of imaging, indicating that cerebral blood flow has increased.
