Visual 3d lower body3/10/2024 ![]() ![]() Concurrent validity was analyzed using Pearson Correlation Coefficient ( r). Intrarater reliability was analyzed by ICC (2,k) with a 95% CI using two repeated trials for each shoulder movement (flexion, abduction, external rotation, internal rotation) that were recorded simultaneously via two methods: a standard goniometer and a 3D motion capture system. Methods/materialsįorty healthy volunteers (mean ± SD, age 27.4 ± 12.4 years, height 173.4 ± 11.1 cm, weight 72.1 ± 16.2 kg) participated in this study. Quasi-experimental reliability, convenience sampling. ![]() The purpose of this study was to investigate the reliability and concurrent validity of this 3D motion capture system compared to a goniometer in assessing ROM of the glenohumeral joint. However, the reliability and validity of a markerless 3D motion capture system that uses a single camera has not been established. One such advancement has been the implementation of a single camera, markerless, and portable 3D motion capture system designed to obtain ROM measurements for multiple body parts simultaneously. Recent technological advancements have enabled medical, sport, and fitness professionals to utilize digital tools that assist with conducting movement examinations and screenings. ![]()
