In the simulation process, the \u0263 correlation coefficient of the Pearson difference between the ROMSS and the universal goniometer was 0.90, the standard deviations of the general goniometer measurements were between \u00b12 degrees and \u00b12.6 degrees, and the standard deviations between the ROMSS measurements were between \u00b10.5 degrees and \u00b11.6 degrees. With the ROMSS, a cloud database was also established; the data measured by the sensor could be uploaded to the cloud database in real-time to provide timely patient information for healthcare professionals. We also developed a mobile app for smartphones to enable patients and healthcare providers to easily trace the data in real-time. Historical data sets with joint activity angles could be retrieved to observe the progress or effectiveness of disease recovery so the quality of care could be properly assessed and maintained.<\/jats:p>","DOI":"10.3390\/s22134684","type":"journal-article","created":{"date-parts":[[2022,6,22]],"date-time":"2022-06-22T04:12:01Z","timestamp":1655871121000},"page":"4684","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Development of Joint Activity Angle Measurement and Cloud Data Storage System"],"prefix":"10.3390","volume":"22","author":[{"given":"Chiu-Ching","family":"Tuan","sequence":"first","affiliation":[{"name":"Department of Electronic Engineering, National Taipei University of Technology, Taipei 10608, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yi-Chao","family":"Wu","sequence":"additional","affiliation":[{"name":"Interdisciplinary Program of Green and Information Technology, National Taitung University, Taitung 95092, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2858-5552","authenticated-orcid":false,"given":"Wen-Ling","family":"Yeh","sequence":"additional","affiliation":[{"name":"Department of Orthopedics, Lotung Poh-Ai Hospital, Yilan 26546, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chun-Chieh","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology, Chang Gung Memorial Hospital at Linkou, Taoyuan 33305, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9348-0899","authenticated-orcid":false,"given":"Chi-Heng","family":"Lu","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology, Chang Gung Memorial Hospital at Linkou, Taoyuan 33305, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shao-Wei","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Electronic Engineering, National Taipei University of Technology, Taipei 10608, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jack","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology, RWJ Medical School, Monmouth Medical Center, Long Branch, NJ 07740, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3112-3594","authenticated-orcid":false,"given":"Tsair-Fwu","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Electronics Engineering, National Kaohsiung University of Science and Technology, Kaohsiung 80708, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hsuan-Kai","family":"Kao","sequence":"additional","affiliation":[{"name":"Bone and Joint Research Center, Chang Gung Memorial Hospital, Linkou 33305, Taiwan"},{"name":"College of Medicine, Chang Gung University, Taoyuan 33305, Taiwan"},{"name":"Department of Orthopedic Surgery, Chang Gung Memorial Hospital at Linkou, Taoyuan 33305, Taiwan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"215","DOI":"10.1177\/1758573217728711","article-title":"Normative values and affecting factors for the elbow range of motion","volume":"11","author":"Zwerus","year":"2019","journal-title":"Shoulder Elbow"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"88","DOI":"10.1007\/s12565-016-0376-4","article-title":"The significance of the supratrochlear aperture (STA) in elbow range of motion: An anatomical study","volume":"93","author":"Ndou","year":"2018","journal-title":"Anat.
