中文摘要：

目的：比较艾灸阳陵泉对慢性背部肌筋膜疼痛综合征（MPS）患者和健康者体表热像的即刻影响。方法：将35例MPS患者作为观察组，将15例健康者作为对照组，采用ATIR-M301医用红外热成像仪对两组艾灸阳陵泉15min前后的体表热像变化进行观察。采用图像定性分析和温度定量分析相结合，比较两组体表热像差异。结果：观察组MPS患者背部红外热像图表现，88。6％有异常热区，分布在上段的最多，其次是下段；有约一半左右的患者脊柱热力线中断或消失；71．4％的患者主诉的疼痛部位和红外热像图表现部位一致。观察组背部上段异常热区的左右侧温差与对照组相比差异有统计学意义（P〈0．001）。艾灸阳陵泉对MPS患者以及健康者的背部体表热像均有影响，以上段和菱形窝最为显著；艾灸阳陵泉对MPS患者背部上段的升温程度较健康者更为明显（P〈0．05）。结论：艾灸阳陵泉可对慢性背部MPS患者背部热像有即刻改善作用。

英文摘要：

Objective To compare the immediate effect of moxibustion on Yanglingquan （GB 34） on body surface thermograph between the patients with myofascial pain syndrome （MPS） and healthy people. Methods Thirty-five cases of MPS were selected in observation group and 15 cases of healthy people were in control group. ATIR-M301 medical infrared imaging device was used to observe the changes in body surface thermograph before and 15 min after moxibustion on Yanglingquan （GB 34）. The qualitative analysis of picture pattern and the quantitative analysis of temperature were integrated to compare the differences between two groups. Results Concerning to the infrared thermograph expression on the back of MPS cases in observation group, the abnormal thermal zone presented in 88. 6% of the cases, mostly distributed in the upper and secondly in the lower back. The spinal thermal line was broken or disappeared in about 50% of cases. The location of pain complained by 71.4% of cases was coincident with the zone of infrared thermograph expression. There was statistical significant difference in the temperature difference of the two sides in the upper abnormal thermal zone on the back in observation group as compared with control group （P（0. 001）. Body surface thermograpb on the back were impacted by moxibustion on Yanglingquan （GB 34） for either MPS patients or healthy people, especially in upper back and rhomboid fossa. Moxibustion on Yanglingquan （GB 34） increased much more apparently the temperature on the upper back in MPS patients as compared with healthy people （P〈0. 05）. Conclusion Moxibustion on Yanglingquan （GB 34） brings the immediate improvements in the back thermograph for MPS patients.
