Abstract Introduction Scapular dyskinesis is a condition responsible for alteration of the normal position and kinematics of the scapula rather than a disease. It can thus be found in healthy individuals or be responsible for a syndrome characterised by several symptoms and objective findings, called SICK, which indicates the main features of the disease. Our purpose is to describe the anatomic...

The purpose of this study was to test the hypothesis that shoulder rhythm is affected by rotator cuff pathology during arm elevation. We divided 42 subjects into 3 groups: those with full-thickness rotator cuff tears (RCTs) (n = 14), those with tendinopathy (n = 13), and control subjects (n = 15). Shoulder kinematics was recorded while subjects performed elevation in the sagittal and scapular p...

BACKGROUND AND PURPOSE Treatment of patients with impingement symptoms commonly includes exercises intended to restore "normal" movement patterns. Evidence that indicates the existence of abnormal patterns in people with shoulder pain is limited. The purpose of this investigation was to analyze glenohumeral and scapulothoracic kinematics and associated scapulothoracic muscle activity in a group...

This was the third research meeting focused on scapular function and dysfunction, following similar meetings in 2003 and 2006. The purpose of this meeting, hosted by the Shoulder Center of Kentucky, was to continue to examine the biomechanical and clinical factors thought to be associated with the role of the scapula in shoulder function and dysfunction. Since the last Summit, much more informa...

Assessment of scapulothoracic and glenohumeral contributions to shoulder function during baseball pitching are limited by challenges in accurately measuring dynamic scapular orientation. A recently validated individualized linear model approach that estimates orientation based on measurable humerothoracic has yet be adapted for may improve upon currently recommended methods such as the acromion...

The mobility of the shoulder girdle is a complex interaction of arthrology and neuromotor control[1]. Over 780,000 persons in the United States have a new or recurrent stroke each year. Residual, motor impairments such as weakness and incoordination can lead to changes in shoulder function and mobility. Alterations in shoulder elevation and scapular upward rotation are related to shoulder pain ...

INTRODUCTION In a healthy shoulder, as the humerus elevates, the scapula rotates upward and tilts posteriorly. Factors are known to influence the magnitude of this response such as the plane of elevation [1]; however, gender is rarely tested as a factor. This is remarkable, as gender is known to influence kinematic and injury outcomes at other joints, such as at the knee [2]. Therefore the purp...
