Figure 5From: The reliability of three-dimensional scapular attitudes in healthy people and people with shoulder impingement syndrome Intersession intraclass correlation coefficients of 3D scapular attitudes for the two populations. The intersession intraclass correlation coefficients (ICCs) of 3D scapular attitudes (anterior/posterior tilting (A-PT), lateral/medial rotation (L-MR) and protraction/retraction (PRO-RET)) was measured in three static shoulder positions (arm at rest, 70° of flexion, 90° of abduction) using the method of calculation relative to the trunk in healthy subjects (n = 30 shoulders) and subjects with SIS (n = 8 shoulders for impaired shoulders and non-impaired shoulders).Back to article page
