Change of paw volume and paw withdrawal thresholds at base, 5 h, 6 h, and 25 h after NS/CFA injection in control group, model group, and TENS group. A) Paw volumes were measured by a water plethysmometer. B) PWTs were assessed by using dynamic plantar aesthesiometer. Values represent mean ± SEM; n = 10 for per group. **P < 0.01 versus control group at the corresponding time point. ▲▲ P < 0.01 versus model group at the corresponding time point.
