This study evaluates the reliability and validity of the smartphone \u201cClinometer\u201d app in measuring scapular upward rotation (UR) and anteroposterior tilt. Design<\/jats:bold>:<\/jats:italic> Psychometric analysis. Methods<\/jats:bold>:<\/jats:italic> We recruited 57 participants\u201410 with and 47 without shoulder pain. Two physical therapists consecutively measured both scapular movements using the Clinometer app at the arm by the side (rest), 30\u00b0, 60\u00b0, 90\u00b0, and 120\u00b0 of humeral elevation in the scapular plane; one therapist measured again after 2\u00a0days. For evaluating concurrent validity, we compared the Clinometer scores with those measured using an electromagnetic motion capture system in 10 healthy participants. Intraclass correlation coefficients (ICC) with standard error of measurement (SEM) and minimal detectable difference at 90% confidence intervals (MDD90<\/jats:sub>) were calculated. Concurrent validity was evaluated using repeated-measures analysis of variance followed by post hoc testing with Tukey\u2013Kramer test (P<\/jats:italic>\u2009<\u2009.05). Results<\/jats:bold>:<\/jats:italic> We observed good intrarater reliability (ICC: UR\u2009=\u2009.76\u2013.85, tilt\u2009=\u2009.69\u2013.9; SEM: 2.2\u00b0\u20133.5\u00b0; MDD90<\/jats:sub>: \u223c5\u00b0\u20138\u00b0) and moderate to good interrater reliability (ICC: UR\u2009=\u2009.66\u2013.78, tilt\u2009=\u2009.66\u2013.76; SEM: 3.6\u00b0\u20138\u00b0; MDD90<\/jats:sub>: \u223c9\u00b0\u201318\u00b0) for both rotations. The Clinometer scores for UR were comparable to electromagnetic motion capture system at all angles except 90\u00b0 (difference \u223c8\u00b0); for scapular tilt, the scores were comparable only at rest and 30\u00b0 elevation. Conclusion<\/jats:bold>:<\/jats:italic> The Clinometer app is reliable and valid for measuring scapular UR throughout and for scapular tilt at lower humeral elevation angles. The MDD90<\/jats:sub> values for scapular rotations computed in this study can be helpful in rehabilitation planning and future research.<\/jats:p>","DOI":"10.1123\/jsr.2023-0005","type":"journal-article","created":{"date-parts":[[2023,8,29]],"date-time":"2023-08-29T08:34:18Z","timestamp":1693298058000},"page":"926-931","source":"Crossref","is-referenced-by-count":3,"title":["Reliability and Concurrent Validity of Smartphone Clinometer Application for Measuring Scapular Rotations in Subjects With and Without Shoulder Pain"],"prefix":"10.1123","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6901-7618","authenticated-orcid":true,"given":"Varmeet","family":"Kaur","sequence":"first","affiliation":[{"name":"Indian Spinal Injuries Centre, Institute of Rehabilitation Sciences, New Delhi, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3395-2214","authenticated-orcid":true,"given":"Meena","family":"Makhija","sequence":"additional","affiliation":[{"name":"Indian Spinal Injuries Centre, Institute of Rehabilitation Sciences, New Delhi, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8840-1487","authenticated-orcid":true,"given":"Vandana","family":"Phadke","sequence":"additional","affiliation":[{"name":"Department of Research, Indian Spinal Injuries Centre, New Delhi, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"100","reference":[{"key":"r1","series-title":"Phys Ther","first-page":"1162","article-title":"Critical and theoretical perspective on scapular stabilization: what does it really mean, and are we on the right track?","volume":"96","author":"Mcquade KJ","year":"2016","unstructured":"Mcquade KJ, Borstad J, Siriani De Oliveira A, Mcquade KJ, Borstad J, De Oliveira AS.
