(1) Background: Actigraphic methods allow prolonged monitoring of human physical activity (PA) by wearable sensors in a real-life unsupervised context. They generally do not characterize the social context, and nearby persons can have a modulating effect on the performed PA. The present study aims to apply an existing method for bimanual actigraphy to both components of a marital dyad to verify the level of association between the two PA profiles. Other dyad comparisons complete the overall figure. (2) Methods: Seven-day actigraphic recordings collected from both components of 20 married couples of retired, cohabiting, healthy subjects (age ranging from 58 to 87 years) were considered. (3) Results: PA profiles of a marital dyad are significantly more correlated (coefficient: 0.444) than unrelated couples (0.278). Interestingly, participants' profiles compared with their own recording shifted by 24 h, evidencing an intermediate level of association (0.335). Data from the literature, the high association (0.875) of individual right and left wrist profiles, enforce the analysis. (4) Conclusions: The proposed method, called "social actigraphy", confirmed that the partner has a relevant effect on one's PA profile, thus suggesting involving the partner in programs concerning lifestyle changes and patient rehabilitation.
(1) 背景：活动记录仪方法允许通过可穿戴传感器在真实的非监督环境中对人体的身体活动（PA）进行长时间监测。它们通常无法描述社会环境，并且附近的人可能会对所进行的 PA 产生调节作用。本研究旨在将现有的双手活动记录仪方法应用于婚姻伴侣的两个组成部分，以验证两个 PA 谱之间的关联程度。其他的对偶比较完成了整体情况。
(2) 方法：考虑了来自 20 对已退休、同居、健康的已婚夫妇（年龄在 58 至 87 岁之间）的两个组成部分的为期 7 天的活动记录仪记录。
(3) 结果：婚姻伴侣的 PA 谱显著更相关（系数：0.444），而无关的夫妇（0.278）。有趣的是，与参与者自己的记录相比，他们的记录移动了 24 小时，表明存在中等水平的关联（0.335）。来自文献的数据，个体右手和左手腕谱的高度关联（0.875），加强了分析。
(4) 结论：所提出的方法称为“社会活动记录仪”，证实了伴侣对一个人的 PA 谱有相关影响，因此建议在涉及生活方式改变和患者康复的计划中涉及伴侣。
