The dynamic changes of the pain thresholds (Heat-Withdrawal Latency, HWL and Stimulation-Vocalization Threshold, Voc) in the adjuvant-induced arthritic rats and the effects of EA on the pain thresholds, skin temperature and the circumference of the diseased ankle were observed. Both pain thresholds were obviously decreased in affected limbs in EA and control groups. But in the normal limbs, HWL decreased and Voc, no changed. In EA group, the ankle circumference and skin temperature were markedly lower than that in control group. The increase of the body weight was much more obvious than that in control group. Our experiment revealed that EA could not only increase the pain threshold, but also improve the pathological changes in the inflammation of the ankle, the mechanisms of the changes of the pain thresholds and the effects of EA in the arthritic rats were discussed.
观察佐剂诱导的关节炎大鼠疼痛阈值（热退缩潜伏期，HWL和刺激发声阈值，Voc）的动态变化以及电针对疼痛阈值、皮肤温度和患病踝关节周长的影响。电针组和对照组患侧肢体的两种疼痛阈值均明显降低。但在正常肢体中，HWL降低而Voc无变化。电针组踝关节周长和皮肤温度明显低于对照组。体重增加比对照组明显得多。我们的实验表明，电针不仅可以提高疼痛阈值，还可以改善踝关节炎症的病理变化，并讨论了疼痛阈值变化的机制以及电针在关节炎大鼠中的作用。
