“…Rather than compressing the humeral head into the glenoid fossa, the scapula may be pulled in a lateral direction around the thoracic wall [19,36]. Additionally, the protracted scapula can increase strain on the anterior capsule and, when combined with GIRD, potentiates the risk for shoulder instability [13,16] and internal impingement [18,20] to develop by narrowing the subacromial space and allowing increased translation of the humeral head in relation to the glenoid [14,19,24,29,31,36,37]. Clinically, these results indicate baseball players with GIRD (15°or greater) have an associated increase of dominant arm scapular protraction, which may increase their risk of shoulder injuries.…”

Background Anecdotal evidence suggests an association between glenohumeral internal rotation deficits (GIRD) and scapular dysfunction, an observable alteration in the normal position or motion of the scapula in relation to the thoracic cage. Questions/purposes We therefore hypothesized players with GIRD (15°or greater) will have decreased dominant arm scapular upward rotation and increased scapular protraction compared with baseball players with GIRD (14°or less). Methods We studied 43 baseball players with no current shoulder or elbow symptoms; 22 had GIRD 15°or greater and 21 had GIRD 14°or less. We measured glenohumeral internal rotation supine with the scapula stabilized. Scapular upward rotation was tested at rest; 60°, 90°, and 120°a bduction in the scapular plane; and scapular protraction at 0°, hands on hips, and 90°abduction in the scapular plane.

“…In general, it is associated with factors such as health, longevity, occupational satisfaction, pleasure, salary, and disposition, and it can define vital aspects of life, such as status and personal identity 2 . Some studies indicate that nurses are at high risk of acquiring work-related musculoskeletal disorders as an increasing number of disabled workers can be seen due to compromised musculoskeletal function [3][4][5] . Some tasks, which require pulling or pushing hospital beds and stretchers with the arms at extension especially during patient transfers, are conducted with static postures and elevation maneuvers of the shoulders and have been associated with shoulder pain 6 .…”

“…During arm elevation, the scapula should have an upward rotation movement and posterior tilting, and during external shoulder rotation, protraction must occur with retraction and internal rotation 16) . The results of the present study show that internal and external shoulder rotation increased after scapular stabilizing exercise.…”

Abstract.[Purpose] The aim of this study was to compare pain, range of motion, isokinetic strength, and endurance in patients with partial-thickness rotator cuff tear, before and after scapular stabilizing exercise.[Subjects] The participants included 12 male patients diagnosed with partial-thickness rotator cuff tear after a magnetic resonance imaging examination in a metropolitan hospital in Korea.[Methods] All participants were tested for pain, range of motion, isokinetic strength, and endurance and were retested after 8 weeks of a scapular stabilizing exercise program in which they participated for 30 minutes a day, 3 days a week.[Results] The differences in visual analogue scale, range of motion, isokinetic strength, and endurance before and after the exercise program were significant.[Conclusion] Patients with partial-thickness rotator cuff tear showed improvements in the areas of pain, range of motion, isokinetic strength, and endurance after scapular stabilizing exercise. Thus, rehabilitation using scapular stabilization exercises improves shoulder function in patients with partial-thickness rotator cuff tear.
