Here, we test the feasibility of using an inertial sensor fitted across the sacrum to measure change in pelvic tilt, and hence screen for patients with high pelvic mobility. Patients (n = 32, mean age: 57.4 years) due to receive THA surgery participated in the study. Measures of pelvic tilt were captured simultaneously using the device and radiograph in three functional positions: Standing, flexed-seated, and step-up. We found a strong correlation between the device and radiograph measures for the change in pelvic tilt measure from standing to flexed-seated position (R2 = 0.911); 75% of absolute errors were under 5 degrees. We demonstrated that the device can be used as a screening tool to rapidly identify patients who would benefit from more detailed surgical planning of implant positioning to reduce future risks of impingement and dislocation.<\/jats:p>","DOI":"10.3390\/s20216182","type":"journal-article","created":{"date-parts":[[2020,10,30]],"date-time":"2020-10-30T09:29:32Z","timestamp":1604050172000},"page":"6182","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["A Sensor-Based Screening Tool for Identifying High Pelvic Mobility in Patients Due to Undergo Total Hip Arthroplasty"],"prefix":"10.3390","volume":"20","author":[{"given":"Xueyang","family":"Wang","sequence":"first","affiliation":[{"name":"WMG, University of Warwick, Coventry CV4 7AL, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arham","family":"Qureshi","sequence":"additional","affiliation":[{"name":"University Hospitals Coventry &amp; Warwickshire NHS Trust, Coventry CV2 2DX, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5858-1109","authenticated-orcid":false,"given":"Abhinav","family":"Vepa","sequence":"additional","affiliation":[{"name":"University Hospitals Coventry &amp; Warwickshire NHS Trust, Coventry CV2 2DX, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Usama","family":"Rahman","sequence":"additional","affiliation":[{"name":"University Hospitals Coventry &amp; Warwickshire NHS Trust, Coventry CV2 2DX, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arnab","family":"Palit","sequence":"additional","affiliation":[{"name":"WMG, University of Warwick, Coventry CV4 7AL, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark A.","family":"Williams","sequence":"additional","affiliation":[{"name":"WMG, University of Warwick, Coventry CV4 7AL, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Richard","family":"King","sequence":"additional","affiliation":[{"name":"University Hospitals Coventry &amp; Warwickshire NHS Trust, Coventry CV2 2DX, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4000-0198","authenticated-orcid":false,"given":"Mark T.","family":"Elliott","sequence":"additional","affiliation":[{"name":"WMG, University of Warwick, Coventry CV4 7AL, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,10,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"635","DOI":"10.1007\/s00264-016-3345-6","article-title":"Total hip arthroplasty instability in Italy","volume":"41","author":"Falez","year":"2017","journal-title":"Int.
