[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...

Összefoglaló. Bevezetés: A megváltozott statikus és/vagy dinamikus lapockapozíciót, azaz a scapuladyskinesist gyakran vonják párhuzamba vállelváltozásokkal. Mindemellett lapocka kinematikai eltérései nagy számban jelen lehetnek tünetmentes egyéneknél is, melegágyat biztosítva későbbi vállelváltozások kialakulásának. Célkitűzés: Munkánk fő célja az volt, hogy felhívja figyelmet ezen problémakör ...

The biomechanical changes due to increased arm mass in individuals with high body mass index (BMI) may lead to altered scapular motions at the shoulder joint. Scapula kinematic alterations are often associated with shoulder pain and pathology, and if present in overweight or obese individuals could impact shoulder health. The purpose of this study was to examine if scapula biomechanics differ b...

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...

[Purpose] This study aimed to investigate the effect of trapezius muscle isometric strength on three-dimensional scapular kinematics in asymptomatic shoulders. [Subjects and Methods] Thirty asymptomatic subjects were included to the study. Isometric strengths of the upper, middle, and lower trapezius muscle were measured using a handheld dynamometer. Three-dimensional scapular kinematics was re...

Proper scapular motion is crucial for normal shoulder mechanics. Scapular motion affects glenohumeral joint function during throwing, yet little is known about this dynamic activity. Asymptomatic subjects (10 male and 10 female), ages 21 to 45, were analyzed. Electromagnetic surface sensors on the sternum, acromion, and humerus were used to collect 3-D motion data during three trials of low-vel...

AIM The aim of this retrospective study was to report the scapular fractures in patients with blunt chest trauma and to present the type and the frequency of associated thoracic injuries. MATERIAL AND METHODS Nine patients with fractures of the scapula were included in the study. The mechanisms of the injury, the type of scapular fractures and associated thoracic injuries were analysed. RES...
