  1. Abbreviations: A-PT, anterior-posterior tilting; L-MR, lateral-medial rotation; PRO-RET, protraction-retraction; SIS, shoulder impingement syndrome; SEM, standard errors of measurement; 95%CI; 95% confidence interval.
  2. The method of calculation relative to the trunk was used to calculate the 3D scapular attitudes. The SEM were calculated using the mean of the two first trials of each session.
