We used the GENEActiv smartwatch to passively collect actigraphy, wrist temperature, and ambient light data from 27 participants after stroke or probable brain transient ischemic attack (TIA) over 42 periods of device wear. We computed 323 features using established algorithms and proposed 25 novel features to characterize sleep and temperature. We investigated statistical associations between the extracted features and clinical outcomes evaluated using clinically validated questionnaires to gain insight into post-stroke recovery. We subsequently fitted logistic regression models to replicate clinical diagnosis (stroke or TIA) and disability due to stroke. The model generalization performance was assessed using a leave-one-subject-out cross validation method with the selected feature subsets, reporting the area under the curve (AUC). We found that several novel features were strongly correlated (|r|&gt;0.3) with stroke symptoms and mental health measures. Using selected novel features, we obtained an AUC of 0.766 to estimate diagnosis and an AUC of 0.749 to estimate whether disability due to stroke was present. Collectively, these findings suggest that features extracted from the temperature smartwatch sensor may reveal additional clinically useful information over and above existing actigraphy-based features.<\/jats:p>","DOI":"10.3390\/s23031069","type":"journal-article","created":{"date-parts":[[2023,1,17]],"date-time":"2023-01-17T05:40:02Z","timestamp":1673934002000},"page":"1069","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["New Insights into Stroke from Continuous Passively Collected Temperature and Sleep Data Using Wrist-Worn Wearables"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2465-5808","authenticated-orcid":false,"given":"Katherine","family":"Edgley","sequence":"first","affiliation":[{"name":"MRC Centre for Reproductive Health, University of Edinburgh, Edinburgh EH16 4TJ, UK"}]},{"given":"Ho-Yan Yvonne","family":"Chun","sequence":"additional","affiliation":[{"name":"Centre for Clinical Brain Sciences, University of Edinburgh, Edinburgh EH16 4SB, UK"}]},{"given":"William N.","family":"Whiteley","sequence":"additional","affiliation":[{"name":"Centre for Clinical Brain Sciences, University of Edinburgh, Edinburgh EH16 4SB, UK"},{"name":"Usher Institute, Edinburgh Medical School, University of Edinburgh, Edinburgh EH16 4UX, UK"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0994-8100","authenticated-orcid":false,"given":"Athanasios","family":"Tsanas","sequence":"additional","affiliation":[{"name":"Usher Institute, Edinburgh Medical School, University of Edinburgh, Edinburgh EH16 4UX, UK"},{"name":"Alan Turing Institute, London NW1 2DB, UK"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"8409","DOI":"10.1038\/s41598-018-26630-y","article-title":"Post-stroke insomnia in community-dwelling patients with chronic motor stroke: Physiological evidence and implications for stroke care","volume":"8","author":"Sterr","year":"2018","journal-title":"Sci.
