For such tasks, mobile devices have several sensors, facilitating the acquisition of diverse data. This study focuses on the analysis of the data collected from the mobile devices sensors and a pressure sensor connected to a Bitalino device for the measurement of the Timed-Up and Go test. The data acquisition was performed within different environments from multiple individuals with distinct types of diseases. Then this data was analyzed to estimate the various parameters of the Timed-Up and Go test. Firstly, the pressure sensor is used to extract the reaction and total test time. Secondly, the magnetometer sensors are used to identify the total test time and different parameters related to turning around. Finally, the accelerometer sensor is used to extract the reaction time, total test time, duration of turning around, going time, return time, and many other derived metrics. Our experiments showed that these parameters could be automatically and reliably detected with a mobile device. Moreover, we identified that the time to perform the Timed-Up and Go test increases with age and the presence of diseases related to locomotion.<\/jats:p>","DOI":"10.3390\/s20123481","type":"journal-article","created":{"date-parts":[[2020,6,19]],"date-time":"2020-06-19T12:19:55Z","timestamp":1592569195000},"page":"3481","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["Mobile Computing Technologies for Health and Mobility Assessment: Research Design and Results of the Timed Up and Go Test in Older Adults"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9317-5250","authenticated-orcid":false,"given":"Vasco","family":"Ponciano","sequence":"first","affiliation":[{"name":"R&amp;D Unit in Digital Services, Applications and Content, Polytechnic Institute of Castelo Branco, 6000-767 Castelo Branco, Portugal"},{"name":"Altranportugal, 1990-096 Lisbon, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3394-6762","authenticated-orcid":false,"given":"Ivan Miguel","family":"Pires","sequence":"additional","affiliation":[{"name":"Instituto de Telecomunica\u00e7\u00f5es, Universidade da Beira Interior, 6200-001 Covilh\u00e3, Portugal"},{"name":"Department of Computer Science, Polytechnic Institute of Viseu, 3504-510 Viseu, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1225-3844","authenticated-orcid":false,"given":"Fernando Reinaldo","family":"Ribeiro","sequence":"additional","affiliation":[{"name":"R&amp;D Unit in Digital Services, Applications and Content, Polytechnic Institute of Castelo Branco, 6000-767 Castelo Branco, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4957-9477","authenticated-orcid":false,"given":"Mar\u00eda Vanessa","family":"Villasana","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Universidade da Beira Interior, 6200-506 Covilh\u00e3, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3009-0612","authenticated-orcid":false,"given":"Rute","family":"Cris\u00f3stomo","sequence":"additional","affiliation":[{"name":"Polytechnic Institute of Castelo Branco, 6000-084 Castelo Branco, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria","family":"Canavarro Teixeira","sequence":"additional","affiliation":[{"name":"UTC de Recursos Naturais e Desenvolvimento Sustent\u00e1vel, Polytechnique Institute of Castelo Branco, 6001-909 Castelo Branco, Portugal"},{"name":"CERNAS\u2014Research Centre for Natural Resources, Environment and Society, Polytechnique Institute of Castelo Branco, 6001-909 Castelo Branco, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7664-0168","authenticated-orcid":false,"given":"Eftim","family":"Zdravevski","sequence":"additional","affiliation":[{"name":"Faculty of Computer Science and Engineering, University Ss Cyril and Methodius, 1000 Skopje, North Macedonia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,6,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Marques, G., Pitarma, R., Garcia, N.M., and Pombo, N.
