基于中医体质和红外热成像技术对腰椎间盘突出症(Lumbar Disc Herniation, LDH)人群进行流行病学调查，并分析了该人群的体质及红外皮温分布特点。对符合LDH纳入标准的243例人员采用标准化的中医体质量表判别和分析其体质类型;利用红外热成像技术观察腰骶椎投影区和双下肢神经支配区的皮温分布特点。LDH人群以兼夹体质类型为主，占70.7%。单一体质占26.3%。LDH人群的红外皮温特点表现为在腰骶部正中呈现热偏离，形状呈长条形、片状或小团状。双下肢神经支配区的红外皮温呈现冷偏离。结果表明，LDH人群的优势体质类型为阳虚血瘀质;其红外皮温呈规律性分布。红外热成像技术对LDH具有一定的诊断价值。

An epidemiological survey was conducted on the patients with lumbar disc herniation (LDH) based on traditional Chinese medicine (TCM) constitution and infrared thermal imaging technology. The physical and infrared skin temperature distribution characteristics of the population were analyzed and described. A standardized TCM constitution scale was used to discriminate and analyze the constitution types of 243 patients who met the LDH inclusion criteria. Infrared imaging technology was used to observe the distribution of skin temperature in the lumbar sacral projection area and the nerve innervation area of double lower limbs. The LDH population is dominated by the type of physique, accounting for 70.7%. The single constitution accounts for 26.3%. The infrared skin temperature of the LDH population is characterized by a thermal deviation in the middle of the lumbosacral region. The shape is of long strip, flake or small clumps. Infrared skin temperature in the nerve innervation area of double lower limbs shows a cold deviation. The results show that the dominant constitution type of LDH population is Yang deficiency and blood stasis, its infrared skin temperature is regularly distributed. Infrared thermal imaging technology has certain diagnostic value for LDH.
