Official title
Reliability and Validity of Goniometric iPhone Applications for the Assessment of Active Shoulder External Rotation
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to determine the test-retest and inter-rater reliability and concurrent validity of two iPhone goniometric applications in the measurement of active shoulder external rotation as compared to a standard manual goniometer. The scientific hypotheses for this study are as follows: 1. There will be significant Pearson correlations (\>.8) to demonstrate test-retest reliability for each of the tools between the 1st and 2nd round of testing as assessed by novice testers. 2. There will be significant intra-class correlation coefficients (\>.8) to demonstrate inter-rater reliability between the novice tester and the experienced tester for each of the three tools. 3. There will be significant Pearson correlations (\>.8) to demonstrate concurrent validity between the standard goniometer and the photo capture application, the standard goniometer and the accelerometer-based application and the photo capture application with the accelerometer-based app. as assessed by novice testers.
