基于红外热成像技术的膝骨性关节炎患者穴位体表温度规律研究＊

目的 观察膝骨性关节炎患者穴位体表温度分布规律。方法 以256例膝骨性关节炎患者和256例健康受试者为观察对象。使用Fotric 226红外热像仪检测患者和健康受试者腧穴的温度值，每名患者每周固定时间检测1次，共检测4次，健康人检测1次，比较患者组与健康受试者组穴位温度值的差异，比较不同时间点不同部位、经脉温度值的差异。结果 膝骨性关节炎患者血海穴、鹤顶穴、梁丘穴、曲泉穴、内膝眼穴、犊鼻穴、委阳穴、阴陵泉穴、膝关穴、阳陵泉穴、大杼穴、悬钟穴、足三里穴、命门穴、腰阳关穴温度值高于健康受试者（P < 0.05）；患者组胃经的4次皮温均较高（P < 0.05），腰背部的4次皮温均较高（P < 0.05）；KOA相关腧穴4次温度值变化趋势不显著（P > 0.05）。结论 膝关节骨性关节炎患者部分腧穴皮温升高；膝骨性关节炎患者的穴位升温现象具有规律性，与经络、部位相关；膝关节骨性关节炎相关穴位升温效应具有稳定性。     

Applications of thermal imaging with infrared thermography in Orthopaedics

BackgroundPathological conditions with ongoing inflammatory processes result in specific heat signatures at the affected body parts; infrared thermography (IRT) detects these changes and can be utilied in screening such conditions. The modern devices are advanced and their non contact, convenient and precise readings can aid in multiple medical sub fields. Orthopaedics as a broad entity has witnessed utilisation of this technology for different indications and the present scoping review was done to assess these established indications and further scope of its utility.Methodology: A Medline search was done on April 26, 2021 with specific keywords for studies of any design in English language discussing the usage of thermography in Orthopaedics. Animal studies, conference abstracts, systematic reviews, e-posters, case reports, book chapters, and studies describing the use of thermography in non-Orthopaedic patients were excluded.ResultsTotal number of hits were 1380. 43 studies including case series and case control studies were included in the review. The subfields or indications described were pain/arthritis, Charcot's foot/neuropathic ulcers, infections associated with diabetic feet and arthroplasties, reflex sympathetic dystrophy, carpal tunnel syndrome, sports medicine, paediatric orthopaedics, spine, ergonomics and compartment syndrome.ConclusionIRT has been described to be effective in orthopaedic conditions with specific heat signatures and this can assess the trend of the ongoing inflammatory process as well as response to a particular treatment. Additionally, it can specifically determine the exact loci of the pathology for targeted interventions.     

中药贴敷对社区冠心病患者红外热成像及抑郁量表影响的研究

目的通过患者背俞穴、募穴、原穴等特定穴位红外温度的组间比较研究与自身对照研究,观察贴敷法对冠心病的红外热成像及抑郁量表的影响。方法选取沈阳市皇姑区龙江社区冠心病志愿者20例和健康志愿者20名,分为治疗组与健康组。采用红外热成像技术分析治疗组的温度特异性穴位;采用红外热成像技术、抑郁量表(HAMD)分析治疗效应。结果与健康组相比,发现治疗组体表温度特异性穴位(P<0.05)心俞(左)、心俞(右)、大陵(左)、大陵(右)、膻中;在治疗后进行红外热成像的前后对照研究发现膻中、心俞穴有体表温度变化(P<0.05);治疗后,采用HAMD进行抑郁量表评分,治疗前和治疗后比较差异有统计学意义(P<0.05)。结论冠心病患者背俞穴、募穴、原穴有红外温度低温表现。本研究的贴敷治疗对冠心病患者穴位的刺激可以影响心区体表代谢,贴敷方法还可以缓解冠心病患者抑郁症状。     

软组织损伤红外热像图的诊断价值

目的 探讨软组织损伤颈、肩、腰、腿、肘、腕红外热像图的诊断价值。方法应用WP-95型红外热像仪，对221例常规军事训练1～5年的年轻干部及战士进行红外热像仪的全身检查，并与刚入伍未参加训练的新兵100例进行对照。结果221例经红外热像图检查发现颈、肩、腰、肘、腕出现异常热像图的有180例，占81．45％；而100例新战士仅有6例颈、肩、腰、肘、腕出现异常热像图，占6．00％，两者比较差异有显著性（P〈0．05）。186例异常热像图受检者全部做x线摄片检查，X线摄片异常者仅28例，占15．05％，两者检查比较差异有显著性（P〈0．05）。结论红外热像图对军事训练所致软组织损伤有其独特的异常热像图，为临床提供明确的诊断信息，正确的使用红外热像图，对保证部队广大指战员的健康水平有着重要作用。     

Stimulated infrared thermography applied to differentiate scar tissue from peri-scar tissue: a preliminary study

Every human injury leads to a scar formation. The healing process leads to the formation of new tissue: the scar, which is different from the original tissue. This process is influenced by mechanical strength and the local vasculature is modified. The purpose of this study is to show that there are various temperatures between the scar and the peri-scar area associated with the healing process that can be estimated using the thermal infrared camera. In the study, 12 scars were stimulated by cold. Several changes of temperature were observed between scar and peri-scar area for 10?min. Scars appeared significantly colder with a Wilcoxon test (p?=?0.01). Results showed that stimulated infrared thermography can be used to monitor the temperature difference between the scar and peri-scar tissue.
