Figure 4From: The kinematics of upper extremity reaching: a reliability study on people with and without shoulder impingement syndrome Intrasession standardized error of measurement (SEM). The SEM and its 95% confidence interval are presented for the first two trials, the first five trials and the last five trials out of ten in healthy subjects (n = 20) and for the last five trials in subjects with SIS (n = 30). The SEM are only presented for the last five trials in the SIS groups since the SEM were similar for most joints in subjects with and without SIS. * Significant differences (P < 0.05) for the first two trials and the first five trials compared to the last five trials for healthy subjects. ¶Significant differences (P < 0.05) between healthy subjects and the subjects with SIS.Back to article page
