Understanding the effect of postherpetic neuralgia (PHN)
pain on brain activity is important for clinic
strategies. This is the first study, to our knowledge,
to relate PHN pain to small-world properties of brain
functional networks. Functional magnetic resonance
imaging was used to construct brain functional networks
during the resting state. Sixteen patients with PHN pain
and sixteen age-matched controls were analyzed (8 males,
8 females for both groups). Decreased local efficiency
for PHN in comparison with the healthy controls was
found. Moreover, regional nodal efficiency was found to
be profoundly affected for PHN.
