目前有3种已确定的技术常规用于确定糖尿病患者足部溃疡的风险。这些是对循环、神经病变和足部压力的评估。这些评估被广泛应用于临床和研究领域，目的是预防足部溃疡的发生。常规神经病理学评估包括使用Semmes Weinstein单丝和生物感受器评估足底皮肤的感觉丧失。对足部进行热学测量以评估对热刺激的反应和皮肤的热辨别阈值相对较少见。事实上，关于温度变化在足部溃疡发展中的重要性仍然存在不确定性。随着成像软件和传感器技术的改进，热像仪和温度计在下肢创伤、血管并发症和神经病理性并发症中的应用取得了进展。然而，与特定的热疗方式、成本和处理时间相关的不确定性使其适应于临床。因此，更广泛地采用热学测量受到了限制。本文综述了糖尿病足特有的热测量技术，如电接触测温法、皮肤热辨别阈值、红外热像仪和液晶热像仪。
There are currently 3 established techniques employed routinely to determine the risk of foot ulceration in the patient with diabetes mellitus. These are the assessment of circulation, neuropathy, and foot pressure. These assessments are widely used clinically as well as in the research domain with an aim to prevent the onset of foot ulceration. Routine neuropathic evaluation includes the assessment of sensory loss in the plantar skin of the foot using both the Semmes Weinstein monofilament and the biothesiometer. Thermological measurements of the foot to assess responses to thermal stimuli and cutaneous thermal discrimination threshold are relatively uncommon. Indeed, there remains uncertainty regarding the importance of thermal changes in the development of foot ulcers. Applications of thermography and thermometry in lower extremity wounds, vascular complications, and neuropathic complications have progressed as a result of improved imaging software and transducer technology. However, the uncertainty associated with the specific thermal modality, the costs, and processing times render its adaptation to the clinic. Therefore, wider adoption of thermological measurements has been limited. This article reviews thermal measurement techniques specific to diabetic foot such as electrical contact thermometry, cutaneous thermal discrimination thresholds, infrared thermography, and liquid crystal thermography.
