躁狂抑郁症，也被称为双相情感障碍，是一种常见而严重的精神障碍。欧洲研究项目MONARCA旨在开发和验证移动技术，用于多参数、长期监测与双相情感障碍相关的生理和行为信息。MONARCA的一个方面是研究皮肤电活动（EDA）的长期监测，以支持双相情感障碍患者的诊断和治疗。EDA被认为是一个人的情绪状态和压力水平的指示器。为了实现对EDA的长期监测，将传感器系统集成到鞋子或袜子中是一种很有前途的方法。本文介绍了迈向这种传感器系统的第一步。在一项包括8名受试者的可行性研究中，我们研究了手指（最成熟的传感部位）的EDA测量与足部EDA测量之间的相关性。结果表明，88%的诱发皮肤电导反应（SCRs）发生在两个感应位点。当使用动作电影作为心理生理激活刺激时，我们发现足部EDA的反应性弱于手部EDA。结果还表明，适度的体育活动对EDA测量的影响很低，并且在两个记录地点具有相似的效果。这说明足部记录位置适合在日常生活中，即使在有适度运动的情况下进行记录。
Manic depression, also known as bipolar disorder, is a common and severe form of mental disorder. The European research project MONARCA aims at developing and validating mobile technologies for multi-parametric, long term monitoring of physiological and behavioral information relevant to bipolar disorder. One aspect of MONARCA is to investigate the long term monitoring of Electrodermal activity (EDA) to support the diagnosis and treatment of bipolar disorder patients. EDA is known as an indicator of the emotional state and the stress level of a person. To realize a long-term monitoring of the EDA, the integration of the sensor system in the shoe or sock is a promising approach. This paper presents a first step towards such a sensor system. In a feasibility study including 8 subjects, we investigate the correlation between EDA measurements at the fingers, which is the most established sensing site, with measurements of the EDA at the feet. The results indicate that 88% of the evoked skin conductance responses (SCRs) occur at both sensing sites. When using an action movie as psychophysiologically activating stimulus, we have found weaker reactivity in the foot than in the hand EDA. The results also suggest that the influence of moderate physical activity on EDA measurements is low and has a similar effect for both recording sites. This suggests that the foot recording location is suitable for recordings in daily life even in the presence of moderate movement.
