5. Fig 4
Histograms of the effect of sham-operated and US treatment in animals with CFA-induced arthritis on numbers of nNOS-LI neurons of the L1-2 segments of rat spinal cord ipsilateral (IPSI) and contralateral (CONTRA) to the CFA-injected leg. Each value represents the average number of labeled neurons ± SEM in each group for each laminar distribution. *P<.05; **P<.01; ***P<.001.

6. Fig 5
The spatial distribution proportion (in percent) of nNOS-LI neurons in laminae I–II, III–IV, V–VI, and VII–X in CFA-induced arthritis animals sham-treated or treated with US ipsilateral and contralateral to the injected legs. Significant differences are shown between sham-treated rats and those treated with US in ipsilateral laminae III–IV and laminae V–VI. **P<.01; ***P<.001.
