Internal rotation (bold font) is significantly improved after arthroscopic capsular release. The 2nd ER and IR and the 3rd ER and IR (italic font) were measured at the maximum range of motion of elevation.

AE: anterior elevation; LE: lateral elevation; 1st ER: external rotation in adduction of the shoulder joint; HBB: the highest posterior spinal level reached when hand is behind back; HF: horizontal flexion; 2nd ER: external rotation in 90 degrees of lateral elevation; 2nd IR: internal rotation in 90 degrees of anterior elevation; 3rd ER: external rotation in 90 degrees of anterior flexion; 3rd IR: internal rotation in 90 degrees of anterior elevation; VAS: visual analogue scale.
