“…The scapula alone can move in various ways. Many studies have measured and analyzed shoulder motion with a variety of methods [2][3][4][5][6][7][8] . Scapulohumeral rhythm changes with load or velocity and with the phase of the elevation angle, and thus its value is not constant [8][9][10] .…”

It is commonly thought that the collapse of scapulohumeral rhythm may predict glenohumeral dysfunction 3,5,11) . Upward rotation, posterior tilt, and internal rotation of the scapula reportedly increase with glenohumeral elevation, and the internal and external rotation angles differ significantly between the planes of elevation during glenohumeral flexion, scapular plane elevation, and abduction 4) .…”

The aim of this study was to compare scapular kinematics between men and women during shoulder flexion, scapular plane elevation, and shoulder abduction. Eleven healthy men and 11 healthy women participated in this study. As participants performed shoulder flexion, scapular plane elevation, and abduction at a consistent speed, an electromagnetic motion capture system was used to analyze scapular motion. The change in scapular orientation from its resting position was calculated at 30°, 60°, 90° and 120° of humeral elevation. The study found that scapular upward rotation and posterior tilt angles increased significantly with each successive humeral elevation angle, but less so in women than in men. Scapular internal or external rotation differed significantly according to the plane of elevation, that is the scapula was internally rotated during flexion, with no change during scapular plane elevation, and it was externally rotated during abduction. This variation was more marked in women. This study revealed gender differences in scapular kinematics during shoulder motion. During shoulder elevation, the scapulothoracic joint played a greater role in men than in women, whereas the glenohumeral joint played a greater role in women.

“…The reduced clavicular elevation and increased protraction found in this study in females is similar to findings in clavicular posture in previous studies Sobush et al, 1996). The reduced scapular upward rotation on the right side reported for the whole population has also been reported in other studies reporting a more downward rotated scapula on the dominant side in rightdominant people (Greenfield et al, (1995); Raine and Twomey (1997), Schwartz et al, (2014), Matsuki et al, (2011). Other studies in contrast reported a more retracted clavicle and upwardly rotated scapula (Morais and Pascoal 2013) (Table 6.4-1).…”

Refining scapulothoracic kinematic measurement and characterising scapulothoracic resting posture in those with and without chronic non-specific neck pain

Neck pain is a common and recurrent condition affecting between 30 to 50% of adults in any given year. People experiencing neck pain commonly report difficulties in performing activities involving the upper extremity. Furthermore, clinical trials that have included exercises that target the shoulder girdle have shown beneficial effects in reducing neck pain. These observations are feasible based on the biomechanical dependence of the cervical spine and shoulder girdle, which includes common muscle attachments. However, to date there has been a paucity of studies investigating underlying movement disorders of the shoulder girdle in people with neck pain. This is in part due to the challenges of kinematic measurement in this region. The aim of this thesis is to contribute to the literature concerning the role of the shoulder girdle and thorax complex in neck pain from three perspectives. First, the thesis has further refined and informed measurement methods of shoulder girdle and thoracic kinematics (Studies 1-3). Secondly, the thesis further defined normative kinematics of the region with a focus on upright resting posture (Study 4). Thirdly, the thesis explored differences in shoulder girdle and thoracic resting posture in upright standing in those with and without neck pain (Study 5).Advancement in knowledge concerning normal and impaired function of the shoulder girdle has been hindered by challenges related to 3D motion capture of the shoulder girdle and thorax due to skin movement and the complexity of measuring multiple joints and axes of rotation. Therefore, Study1 focused on refining and validating an acromion marker cluster (AMC) method to track scapular movement with the intent of minimising skin movement error. Although the findings of Study 1 indicated that the refined AMC design did not appear to lessen skin movement error compared to previous designs, it was found to be of comparable accuracy (max RMSE 4.45°) and reliability to previous designs (within-session test-retest ICC 0.79-0.99) and appropriate for use in the subsequent thesis studies. In Study 2 the reliability and validity of the AMC method was further evaluated in its capacity to track the scapula at end range clavicular movements (protraction/retraction, elevation/depression). Establishing its measurement accuracy and reliability (max RMSE 6.6°) in these common directions of scapula motion was necessary as it had been previously unstudied. While Studies 1 and 2 focused on optimising the measurement of scapulothoracic kinematics by ensuring the scapula could be tracked accurately, Study 3 focused on refining the measurement of the relationship between the shoulder girdle and the underlying thorax. This study compared thoracic and shoulder girdle postural relationships expressed in the external reference frame to that expressed in the traditionally used ISB recommended thorax reference frame. Using these different frames of iii reference Study 3 also compared measures of thoracic inclination and thoracic curvature. The findings sho...

“…Hand dominance also has been reported to affect the minimum clinically important difference in patient-reported VAS for rotator cuff disease [22]. In addition, hand dominance affects scapular and clavicular kinematics in nonthrowing patients and kinematics and kinetics in throwing athletes [12,13,23]. There are limited and conflicting data available in the shoulder arthroplasty literature regarding the effect of hand dominance on outcome after TSA [2,4,16,18,20,21].…”

Background Total shoulder arthroplasty (TSA) provides excellent functional outcomes and pain relief in appropriately selected patients. Although it is known to affect other shoulder conditions, the role of hand dominance after TSA has not been reported, to our knowledge. Questions/Purposes We asked: (1) Does TSA of the dominant arm result in greater postoperative ROM compared with TSA of the nondominant arm? (2) Does hand dominance affect validated outcome scores after TSA? Methods We performed a review of all patients who underwent primary TSAs between 2008 and 2011 with a minimum of 12 months followup. During that time, one surgeon performed 156 primary TSAs. One hundred twenty-seven patients met the minimum followup requirement for this analysis (81%), whereas 29 (19%) were lost to followup. Seven patients were excluded for surgical indications other than glenohumeral osteoarthritis. A total of 58 patients underwent TSA of the dominant upper extremity and 62 underwent TSA of the nondominant upper extremity. Patient demographics, preoperative and postoperative ROM, and preoperative and postoperative outcome scores, were collected from the medical records. Student's t-tests and chi-square tests were used for analysis. Demographics and preoperative ROM did not differ between patients undergoing TSA on the dominant or the nondominant upper extremity.Results Dominant-arm TSAs showed greater postoperative forward elevation and external rotation. Postoperative active forward elevation in the dominant group was 151°v ersus 141°in the nondominant group (mean difference, 10°; 95% CI, 1°-18°; p = 0.033). Postoperative active external rotation was 61°in the dominant group, versus 51°i n the nondominant group (mean difference, 10°; 95% CI, 5°-15°; p \ 0.001). Active internal rotation did not differ (dominant, 52°, nondominant, 50°; mean difference, 2°;
