Objective: To evaluate the effect of scapular stabilization during horizontal adduction stretching (cross-body) on posterior shoulder tightness (PST) and passive internal rotation (ER). Design: Randomized controlled trial with single blinding. Setting: Athletic club. Participants: Asymptomatic volleyball players who are women with glenohumeral internal rotation deficit (N=60). Interventions: Subjects were randomly assigned to either horizontal adduction stretching with manual scapular stabilization (n=30) or horizontal adduction stretching without stabilization (n=30). Passive stretching was performed for 3- to 30-second holds in both groups. Main Outcome Measures: Range of motion measurements of PST and IR were performed on the athlete's dominant shoulder prior to and immediately after the intervention. Results: Baseline mean angular measurements of PST and IR for all athletes involved in the study were 62 degrees+/-14 degrees and 40 degrees+/-10 degrees, respectively, with no significant difference between groups (P =.598 and P=.734, respectively). Mean PST measurements were significantly different between groups after the horizontal adduction stretch, with a mean angle of 83 degrees+/-17 degrees among the scapular stabilization group and 65 degrees+/-113 degrees among the nonstabilization group (P < .001). Measurements of IR were also significantly different between groups, with a mean angle of 51 degrees+/-14 degrees among the scapular stabilization group and 43 degrees+/-9 degrees among the nonstabilization group (P=.006). Conclusions: Horizontal adduction stretches performed with scapular stabilization produced significantly greater improvements in IR and PST than horizontal adduction stretching without scapular stabilization.
