Table 2 AROM reproducibility. SD = between-subject standard deviation, CI = confidence interval, sw = within-subject standard deviation, SDD = smallest detectable difference, ICC = intraclass correlation coefficient.

From: Range of shoulder motion in patients with adhesive capsulitis; Intra-tester reproducibility is acceptable for group comparisons
