Abstract

Objectives Background

Social isolation is probably one of the most affected health outcomes in the elderly people, particularly those living alone, due to the COVID-19 pandemic. Therefore, we try to identify it by detecting changes in the elderly such as malnutrition and lack of mobility.

Material and methods

The system consists of two types of sensors installed at various locations in the user's home: Passive infrared (PIR) sensors and reed switch sensors. It was implemented for 15 days in the home of a 26-year-old student living alone, as a first step to later be deployed in the home of elderly people.

Results

Our study showed strong similarities between the activities detected by the algorithm and the real activity pattern of the interviewed individual. In addition, the system was able to identify two daily patterns (weekday and weekend) of the person as he is a student and is present in class during the week.

Conclusion

A system composed of low-cost, unobtrusive, non-intrusive and miniaturized sensors is able to detect meal-taking activity and mobility. These results are an intermediate step in assessing the potential risk of social isolation in older people living alone based on these ADLs.

基于进餐活动和活动能力的独居老年人社会隔离检测

背景由于新冠肺炎大流行，社会隔离可能是老年人，特别是那些独自生活的人，最受影响的健康结果之一。因此，我们试图通过检测老年人的变化来识别它，如营养不良和行动不便。材料和方法该系统由安装在用户家中不同位置的两种类型的传感器组成：无源红外（PIR）传感器和簧片开关传感器。它在一名26岁独居学生的家中实施了15天，这是后来在老人家中实施的第一步。结果我们的研究表明，该算法检测到的活动与受访个体的真实活动模式有很强的相似性。此外，该系统能够识别该人的两种日常模式（工作日和周末），因为他是一名学生，并且在一周内上课。结论由低成本、不引人注目、非侵入性和小型化传感器组成的系统能够检测用餐活动和移动性。这些结果是基于这些ADL评估独居老年人社交孤立潜在风险的中间步骤。

期刊介绍： IRBM is the journal of the AGBM (Alliance for engineering in Biology an Medicine / Alliance pour le génie biologique et médical) and the SFGBM (BioMedical Engineering French Society / Société française de génie biologique médical) and the AFIB (French Association of Biomedical Engineers / Association française des ingénieurs biomédicaux). As a vehicle of information and knowledge in the field of biomedical technologies, IRBM is devoted to fundamental as well as clinical research. Biomedical engineering and use of new technologies are the cornerstones of IRBM, providing authors and users with the latest information. Its six issues per year propose reviews (state-of-the-art and current knowledge), original articles directed at fundamental research and articles focusing on biomedical engineering. All articles are submitted to peer reviewers acting as guarantors for IRBM''s scientific and medical content. The field covered by IRBM includes all the discipline of Biomedical engineering. Thereby, the type of papers published include those that cover the technological and methodological development in: -Physiological and Biological Signal processing (EEG, MEG, ECG…)- Medical Image processing- Biomechanics- Biomaterials- Medical Physics- Biophysics- Physiological and Biological Sensors- Information technologies in healthcare- Disability research- Computational physiology- …
