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-...

The shoulder is a complex joint comprised of many moving parts [1]. Accurately measuring shoulder rhythm is difficult, but imperative due to the shoulders susceptibility to numerous chronic and acute injuries. To identify pathological movement and risk for injury, clinicians typically assess shoulder motion dynamically through observation of humeral raising and lowering phases. However, static ...

[Purpose] This study investigated the changes in acromion and scapular position after short-term overhead work. [Subjects] Twelve males aged 20-27 years, were recruited. [Methods] We measured the acromial angle and scapular inferior distance using a palpation meter before and after overhead work. [Results] The acromion angle was significantly decreased after the overhead work compared to before...

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...

Introduction: Scapular dyskinesis is an abnormality in scapula static or dynamic position. There are several techniques for scapular conservative treatment, including Kinesio Tape application, which used to promote and support joint alignment, decrease pain improve local muscle control. Objective. To investigate the effect of kinesio tape on kinematics subjects with dyskinesis. Methods. Fourtee...

Purpose: Scapular dyskinesia is a change in position or movement of scapula, which is highly prevalent in athletes with overhead activities. In addition to biomechanical changes in shoulder complex, neurocognitive impairments can have a significant role in its creation. Thus, this study aimed to compare neurocognitive scores between athletes with and without scapular dyskinesia. Methods: I...

INTRODUCTION Shoulder injuries are common in baseball players, which may be related to scapular malposition (Burkhart 2003). Although a few studies demonstrated scapular malposition in baseball players using clinical measurement (Laudner 2010, Thomas 2010), no data currently exist that demonstrated 3-dimentional (3D) scapular position and orientation using a technique that eliminates skin artif...

Knowledge of three-dimensional scapular movements is essential to understand post-stroke shoulder pain. The goal of the present work is to determine the feasibility and the within and between session reliability of a movement protocol for three-dimensional scapular movement analysis in stroke patients with mild to moderate impairment, using an optoelectronic measurement system. Scapular kinemat...
