Abbreviation: SAB, scapular plane abduction.

^*Values are intraclass correlation coefficient (standard error of measurement in degrees for position and mm for translations). Values represent the average reliability across all phases (raising/lowering) and angles of humerothoracic elevation for joint position (30°, 60°, 90°, 110°/120°) or intervals of humerothoracic elevation for translations (30°–60°, 60°–90°, 90°–110°/120°).
