探讨了红外热成像与骨关节炎中医证型之间的关系。采用前瞻性研究方法观察了90例骨关节炎患者，按肾虚髓亏、阳虚寒凝、瘀血阻滞将患者分为3组，每组30例。以30例健康人为对照组，使用HIR-2000A型红外热像仪对四组人进行扫描检查。扫描位置为手掌、手背、膝部和腘窝，并对相应区域的体表温度值进行记录。阳虚寒凝患者与健康人对照组之间的体表温度值差有显著的统计学意义(P<0.01)，瘀血阻滞患者与对照组之间的体表温度值差有统计学意义(P<0.05)；而肾虚髓亏患者的体表温度值与对照组相比，差异无统计学意义(P>0.05)。结果表明，红外热成像可用于骨关节炎中医证型的辅助诊断，对骨关节炎的早诊断、早治疗有重要的临床意义。

The relationship between infrared thermography and traditional Chinese medicine syndrome of osteoarthritis is discussed. 90 patients with osteoarthritis were observed by using a prospective research method. The patients were divided into three groups of kidney vacuity and marrow depletion (Shenxu Suikui), Yang deficiency and cold coagulation (Yangxu Hanning) and Blood stasis (Yuxue Zuzhi). Each group had 30 patients. By taking 30 healthy volunteers as a contrast group, a HIR-2000A medical infrared thermograher was used to scan four groups of people. The scanned range included the palm of the hand, the back of the hand, knee and popliteal. The surface temperature values of the corresponding areas were recorded. The surface temperature difference between the group of patients with Yangxu Hanning and the contrast group was of remarkable statistical significance (P<0.01);that between the group of patients of Yuxue Zuzhi and the contrast group was of statistical significance (P<0.05); that between the group of patients of Shenxu Suikui and the contrat group was of no statistical significance (P>0.05). The results showed that infrared thermography could be used for the auxiliary diagnosis of traditional Chinese medicine syndrome of osteoarthritis. It was of important clinical significance in the early diagnosis and treatment of osteoarthritis.
