Materials and methods
This study was approved by the institutional review board at our institution. The study consisted of two subject groups.
Results
Group 1 consisted of 1046 male subjects and 573 female subjects. Age ranged from 11 to 87 years. The mean range of motion was as follows: forward flexion, 162° in male subjects and 161° in female subjects; abduction, 166° in male subjects and 166° in female subjects; external rotation, 63° in male subjects and 66° in female subjects; and internal rotation, 79° in male subjects and 82° in female subjects. The mean abduction strength was 8.6 ± 2.8 kg in male subjects and 4.6 ± 1.7 kg in female
Discussion
Outcomes scoring is valuable for assessing patients after surgical treatment. It must be clinically reliable and reproducible by different observers of varying experience levels. In our study, with the use of modern strength measurement techniques, there were no significant differences in examination results between an experienced tester in a research setting and trained residents in a clinical setting. This is consistent with the small interobserver differences (mean, 3%) reported by Constant5
