Water polo is an intense sport with extreme physical contact and repetitive shoulder motion that predisposes to injury. The continuous scapular motion and recruitment of the scapular stabilizers to maintain buoyancy expose water polo athletes to the risk of scapular stress fracture. Suspicion should arise when evaluating water polo athletes presenting with shoulder pain.

Study Design: Case control group study. Objectives: To compare scapular position and orientation between baseball players with and without pathologic internal impingement. Background: Scapular dysfunction has been implicated as a contributor to throwing-related pathologic internal impingement of the shoulder due to its role in increasing the contact between the greater tuberosity and posterior-...

BACKGROUND Scapular dyskinesis, or abnormal dynamic scapular control, is a condition that is commonly associated with shoulder pathology but is also present in asymptomatic individuals. Literature varies on whether it represents a cause or symptom of shoulder pathology, but it is believed to be a risk factor for further injury. Clinical identification focuses on visual observation and examinati...

UNLABELLED The impaired performance of the muscles of the scapular region may result in injuries, fatigue, weakness and pain. The main objective of this research was to analyze the scapular positioning during the abduction of the shoulder movement in the frontal, scapular and sagittal plans. METHOD This cross-sectional study comprised a convenience sample of 20 individuals. It was used the di...

Bones of the postcranial skeleton of higher vertebrates originate from either somitic mesoderm or somatopleural layer of the lateral plate mesoderm. Controversy surrounds the origin of the scapula, a major component of the shoulder girdle, with both somitic and lateral plate origins being proposed. Abnormal scapular development has been described in the naturally occurring undulated series of m...

[Purpose] The purpose of this study was to investigate the effects of thoracic extension exercise on scapular alignment and thoracic kyphosis angle. [Subjects and Methods] Ten subjects with a kyphosis angle ≥40° and aged between 20 and 26 years participated in this study. This study investigated the scapular forward distance and thoracic kyphosis angle before and after the thoracic extension ex...

Scapular winging, one of the more common scapulothoracic disorders, is caused by a number of pathologic conditions. It can be classified as primary, secondary, or voluntary. Primary scapular winging may be due to neurologic injury, pathologic changes in the bone, or periscapular soft-tissue abnormalities. Secondary scapular winging occurs as a result of glenohumeral and subacromial conditions a...

Forward head and rounded shoulder posture (FHRSP) is theorized to contribute to alterations in scapular kinematics and muscle activity leading to the development of shoulder pain. However, reported differences in scapular kinematics and muscle activity in those with forward head and rounded shoulder posture are confounded by the presence of shoulder pain. Therefore, the purpose of this study wa...

STUDY DESIGN Controlled laboratory study using a single-group, repeated-measures design. OBJECTIVES To investigate scapular kinematics during both constrained and functional shoulder movements. BACKGROUND Abnormal scapulothoracic joint motion has been associated with pathologies such as shoulder impingement. Constrained protocols are commonly used in the measurement of shoulder kinematics; ...

HYPOTHESIS In this study, we aim to test whether scapular winging results in a significant change in glenohumeral translation in the initial phase of the throwing motion. METHODS Six shoulders underwent an abbreviated throwing motion (ATM) from late cocking to the end of acceleration by use of a validated robotic system. The intact specimens were tested to establish a baseline. The position o...
