To clarify therapeutic modulatory effects on brain activation in pain-related cortex of chronic lumbago using somatosensory stimulation with treatment for pain relief, twenty participants were divided into two groups, S1 activated (S1(+)) and S1 non-activated (S1(-)) group. There were no activated areas in pain-related cortex in S1 (-) group immediately after treatment for pain relief. Immediately after treatment, rs-fMRI of S1(-) group showed a significant signal decrease in contralateral S2 of pain-related network. It was suggested to diminish pain-related network activation by somatosensory stimulation on chronic lumbago immediately after treatment for pain relief.
