热成像是一种众所周知的糖尿病足溃疡风险评估工具，但由于复杂的家庭环境对热成像图像的影响，在家庭环境中并未广泛使用。本研究调查了复杂家庭环境中热成像图像的变化，以确定基于智能手机的热成像在家庭环境中的可行性。招募健康志愿者（年龄> 20岁），并要求他们在一天的不同时间使用附着在自拍杆上的基于智能手机的热成像仪拍摄足底热图像，持续4天。然后使用内容分析法对热图像和相关活动以及环境因素进行分析。对足底热图像上温度最高的区域进行了描述和分类。使用10分Likert量表评价器械可用性，10分代表最高满意度。共分析了10名参与者的140个足底热图像。在12个分类中，基于最高温度位置的三种最常见的模式是内侧足弓（42.1%）、整个足底（10.7%）和前足和内侧足弓（7.9%）。与其他时间点相比，内侧弓模式在觉醒后最常见（67.5%）。器械可用性平均评分为7.5（满分10分）。这项研究是第一个调查在家庭环境中的足底热模式，内侧足弓模式是最常见的热区，这与之前在控制良好的临床环境中的发现相匹配。因此，基于智能手机的热成像作为家庭环境中的自我评估工具可能是可行的。
Thermography is a well-known risk-assessment tool for diabetic foot ulcers but is not widely used in the home setting due to the influence of the complicated home environment on thermographic images. This study investigated changes in thermographic images in complicated home environments to determine the feasibility of smartphone-based thermography in home settings. Healthy volunteers (age > 20 years) were recruited and required to take plantar thermal images using smartphone-based thermography attached to a selfie stick at different times of the day for 4 days. The thermal images and associated activities and environmental factors were then analyzed using content analysis. Areas with the highest temperature on the plantar thermal images were described and categorized. Device usability was evaluated using 10-point Likert scales, with 10 representing the highest satisfaction. A total of 140 plantar thermal images from 10 participants were analyzed. In 12 classifications, the three commonest patterns based on the highest temperature location were medial arch (42.1%), whole plantar (10.7%), and forefoot and medial arch (7.9%). The medial arch pattern is most frequently seen after awakening (67.5%) compared to other time points. Device usability was rated 7.5 out of 10 on average. This study was the first to investigate the plantar thermal patterns in the home settings, and the medial arch pattern was the most common hot area, which matches previous findings in well-controlled clinical settings. Therefore, smartphone-based thermography may be feasible as a self-assessment tool in the home setting.
