“…Pain could also be affected by musculoskeletal factors, such as a slouched sitting posture. In sedentary young adult males, it has been demonstrated that changing a specific position may influence pain level [31,32]. Altered scapular kinematics could be linked to pain in the region of the neck [33].…”

Background: This study intends to summarize the causes, clinical examination, and treatments of scapular dyskinesis (SD) and to briefly investigate whether alteration can be managed by a precision rehabilitation protocol planned on the basis of features derived from clinical tests. Methods: We performed a comprehensive search of PubMed, Cochrane, CINAHL and EMBASE databases using various combinations of the keywords “Rotator cuff”, “Scapula”, “Scapular Dyskinesis”, “Shoulder”, “Biomechanics” and “Arthroscopy”. Results: SD incidence is growing in patients with shoulder pathologies, even if it is not a specific injury or directly related to a particular injury. SD can be caused by multiple factors or can be the trigger of shoulder-degenerative pathologies. In both cases, SD results in a protracted scapula with the arm at rest or in motion. Conclusions: A clinical evaluation of altered shoulder kinematics is still complicated. Limitations in observing scapular motion are mainly related to the anatomical position and function of the scapula itself and the absence of a tool for quantitative SD clinical assessment. High-quality clinical trials are needed to establish whether there is a possible correlation between SD patterns and the specific findings of shoulder pathologies with altered scapular kinematics.

“…Willmore et al [5] showed that a decrease in scapula upward rotation and posterior tilting occur when there is an increase in the compressing and shearing force under the surface of the acromion. Sanchez et al [6] found that the ratio of scapular dyskinesia in the shoulder pain group was higher than that in the pain-free group. The reported scapular dyskinesia is related to an increase in mechanical stress or shoulder injuries.…”

Previous studies have reported that shoulder fatigue leads to scapular dyskinesia and increased mechanical stress. However, none reported the effect of fatigue resistance. To investigate the effect of fatigue resistance on scapular kinematics during repeated arm elevation. Seventeen healthy participants carried out repeated arm elevation with a dumbbell in the scapular plane at the elbow extension position. Using an electromagnetic tracking device, the angle of the scapular upward rotation, scapular posterior tilting, and scapular external rotation were measured. Arm elevation data were interpolated into 100 frames; the first elevation (0%), 25% of iteration count, 50%, 75%, and the final elevation (100%) were analyzed. There was a significant increase in the scapular upward rotation angle between the 100% and 0% iteration count, and a decrease in the scapular posterior tilting angle at 75% and 100%, compared with 0%. There was no significant effect of the condition on the scapular external rotation angle. Muscle fatigue by repeated arm elevation increased the upward rotation angle, which was maintained until just before complete exhaustion. The decrease in the posterior tilting angle was observed before (when the iteration count exceeded 50%) the increase in the upward rotation angle.
