Therefore, to analyse falls it is relevant to understand recovery patterns, including successful and failed attempts to get up from the floor in general. This study analysed different kinematic features of standing up from the floor. We used inertial sensors to describe the kinematics of lie-to-stand transfer patterns of younger and healthy older adults. Fourteen younger (20\u201350 years of age, 50% men) and 10 healthy older community dwellers (\u226560 years; 50% men) conducted four lie-to-stand transfers from different initial lying postures. The analysed temporal, kinematic, and elliptic fitting complexity measures of transfer performance were significantly different between younger and older subjects (i.e., transfer duration, angular velocity (RMS), maximum vertical acceleration, maximum vertical velocity, smoothness, fluency, ellipse width, angle between ellipses). These results show the feasibility and potential of analysing kinematic features to describe the lie-to-stand transfer performance, to help design interventions and detection approaches to prevent long lies after falls. It is possible to describe age-related differences in lie-to-stand transfer performance using inertial sensors. The kinematic analysis remains to be tested on patterns after real-world falls.<\/jats:p>","DOI":"10.3390\/s16081277","type":"journal-article","created":{"date-parts":[[2016,8,12]],"date-time":"2016-08-12T10:05:06Z","timestamp":1470996306000},"page":"1277","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Inertial Sensor Based Analysis of Lie-to-Stand Transfers in Younger and Older Adults"],"prefix":"10.3390","volume":"16","author":[{"given":"Lars","family":"Schwickert","sequence":"first","affiliation":[{"name":"Department of Clinical Gerontology, Robert-Bosch Hospital, Stuttgart 70376, Germany"}]},{"given":"Ronald","family":"Boos","sequence":"additional","affiliation":[{"name":"Department of Clinical Gerontology, Robert-Bosch Hospital, Stuttgart 70376, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5987-447X","authenticated-orcid":false,"given":"Jochen","family":"Klenk","sequence":"additional","affiliation":[{"name":"Department of Clinical Gerontology, Robert-Bosch Hospital, Stuttgart 70376, Germany"},{"name":"Institute of Epidemiology and Medical Biometry, Ulm University, Ulm 89081, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7111-422X","authenticated-orcid":false,"given":"Alan","family":"Bourke","sequence":"additional","affiliation":[{"name":"Department of Neuroscience, Norwegian University of Science and Technology, Trondheim NO-7491, Norway"}]},{"given":"Clemens","family":"Becker","sequence":"additional","affiliation":[{"name":"Department of Clinical Gerontology, Robert-Bosch Hospital, Stuttgart 70376, Germany"}]},{"given":"Wiebren","family":"Zijlstra","sequence":"additional","affiliation":[{"name":"Institute of Movement and Sport Gerontology, German Sport University Cologne, Cologne 50933, Germany"}]}],"member":"1968","published-online":{"date-parts":[[2016,8,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1710","DOI":"10.1056\/NEJM199606273342606","article-title":"Persons found in their homes helpless or dead","volume":"334","author":"Gurley","year":"1996","journal-title":"N.
