Table 2 Mean, standard deviation (SD) and range of the glenohumeral abduction and the external rotation according to observer A and B, followed by the mean differences between both observers, and the frequency of agreement within 5 and 10 degrees.
Tested movements | Observer A (in degrees) | Observer B (in degrees) | Observer A-B (in degrees) | Upper and lower limit of agreement | Agreement (%) within 5° and 10° | |
