PURPOSE: Scapular dyskinesis is a recognized cause of shoulder pain in the throwing shoulder of baseball pitchers and athletes who participate in overhead sports. Past studies have assessed scapular kinematics using electromagnetic tracking devices and have shown a correlation between posterior shoulder tightness and forward scapular posture. The purpose of our study is to evaluate the scapular kinematics, before and after a 4-week posterior stretching protocol in asymptomatic pitchers...

Scapular dyskinesis describes the altered position of the scapula and/or abnormal movements of the scapulothoracic joint. It is caused by bony anatomical variations, bursitis, tumors, and muscular pathological conditions including loss of innervation and fibrosis. Scapular dyskinesis is just as often subclinical as it is symptomatic, and as the periscapular anatomical changes may not result in patient symptoms, a precise diagnosis of the etiology and pathophysiology has been a challenge. Scapular bony prominence is a common etiology of scapular dyskinesis, but does not always result in morbidity...

OBJECTIVES: The function of the scapula is important in normal neck function and might be disturbed in patients with neck pain. The surrounding muscular system is important for the function of the scapula. To date, it is not clear if patients with idiopathic neck pain show altered activity of these scapulothoracic muscles. Therefore, the objective of this study was to investigate differences in deeper and superficial lying scapulothoracic muscle activity between patients with idiopathic neck pain and healthy controls during arm elevation, and to identify the influence of scapular dyskinesis on muscle activity...

The scapula fulfils many roles to facilitate optimal function of the shoulder. Normal function of the shoulder joint requires a scapula that can be properly aligned in multiple planes of motion of the upper extremity. Scapular dyskinesis, meaning abnormal motion of the scapula during shoulder movement, is a clinical finding commonly encountered by shoulder surgeons. It is best considered an impairment of optimal shoulder function. As such, it may be the underlying cause or the accompanying result of many forms of shoulder pain and dysfunction...

A 70-year-old woman had pain and fatigability of her left shoulder with asymmetric scapular position. The medial border of the scapula was more prominent in the left side compared to the right scapula, and scapular motion was different between sides. Magnetic resonance imaging showed a mass on the ventral surface of the scapula. Tumour resection was performed through the medial approach, and the tissue samples were found to be a lipoma with a pathological examination. Post-operatively, her pain immediately disappeared...

BACKGROUND: Scapular orientation and movements can affect the function of the shoulder. However, evidence is limited on whether symptomatic subjects can actively maintain the scapula in a neutral position through conscious control. OBJECTIVE: To investigate whether symptomatic subjects with scapular dyskinesis can achieve optimal scapular movements and associated muscle activities through conscious control. DESIGN: A cross-sectional study...

In this paper, the principal aspects of kinematic and electromyographic (EMG) analysis of the shoulder and their potential for the every-day clinical practice are described. The text reports a brief description of standard recommendations for movement assessment, an overview of the main quantitative motion analysis protocols and a description of the most commonly investigated scapulothoracic muscles. To assess the possibility of using these protocols for clinical applications, reliability and repeatability of kinematic and EMG measures were investigated and reference data for scapulohumeral joint kinematics were provided...

BACKGROUND: Shoulder problems are highly prevalent among elite handball players. Reduced glenohumeral rotation, external rotation weakness and scapula dyskinesis have been identified as risk factors. AIM: Evaluate the effect of an exercise programme designed to reduce the prevalence of shoulder problems in elite handball. METHODS: 45 elite handball teams (22 female teams, 23 male teams, 660 players) were cluster randomised (22 teams, 331 players in the intervention group, 23 teams, 329 players in the control group) and followed for 1 competitive season (7 months)...

Snapping scapula syndrome is a rare condition caused by the disruption of the gliding articulation between the anterior scapula and the posterior chest wall. The etiology of snapping scapula syndrome is multifactorial, and contributing factors include scapular dyskinesis, bursitis from repetitive use or trauma, and periscapular lesions. Although the majority of cases are initially treated with nonoperative modalities, recalcitrant snapping scapula syndrome can warrant surgical management. This report describes a 34-year-old amateur weight lifter with a 1-year history of increasing pain and fullness over his posterior shoulder region...

OBJECTIVE: To compare quantitative muscle activation between erect and slouched sitting postures in the muscles around the scapula, and to investigate the correlation between the angle of thoracic kyphosis and the alteration of muscle activity depending on two different sitting postures. METHODS: Ten healthy males participated in the study. Unilateral surface electromyography (SEMG) was performed for serratus anterior, middle trapezius (MT), and lower trapezius (LT), which are scapular stabilizer muscles, as well as latissimus dorsi...

Scapular dyskinesis in pitchers can potentially lead to impairments in the optimal performance of muscles of the shoulder complex. The purpose of this prospective study was to evaluate whether the use of a scapula stabilizing t-shirt can decrease stress and discomfort in over-head baseball pitchers. Thirty-two semi-professional baseball pitchers were divided into 2 groups. Group A dressed the scapula stabilizing t-shirt during the weekly practice while group B (control group) continued to follow their training program without the t-shirt...

Stabilization exercises have been a focus and mainstay of many therapeutic and performance training programs in the past decade. Whether the focus is core stabilization for the spine or scapular stabilization, clinicians and trainers alike have endorsed these programs, largely on the basis of conceptual theory and anecdotal experience. The notion that an unstable scapula is related to shoulder dysfunction and pathology is well accepted, but is it accurate? The aim of this perspective article is to challenge the concept of scapular stabilization through the application of biomechanical and motor control constructs...

Scapular dyskinesis, characterized by scapular downward rotation syndrome (SDRS) affects scapula-humeral rhythm and results in shoulder dysfunction. Previous study has led to the recommendation of standard shrug exercise to contend with SDRS and strengthen the upper trapezius (UT) muscle. However, few researchers have examined which shrug exercise is most effective. The aim of this research was to compare scapular kinematic changes and scapular rotator muscles activity across three different shrug exercises in SDRS...

BACKGROUND: Because of detachment of the pectoralis minor and variation of the vector of the conjoint tendons, we hypothesized that the Latarjet procedure may alter scapular position and motion. The purpose of this study was to evaluate scapular position and motion in patients who underwent a Latarjet or a modified iliac crest bone graft transfer (ICBGT) procedure (J-bone graft). METHODS: Forty-six consecutive patients treated for recurrent anterior shoulder dislocation between 2010 and 2012 were retrospectively enrolled...

BACKGROUND: The role of the scapula during high-velocity baseball pitching has been described without 3-dimensional kinematic data. It has been speculated that the scapula functions to align the humerus with the spine of the scapula on both the transverse and scapular planes at the end of the arm-cocking phase. HYPOTHESIS: Two hypotheses were formulated: (1) the scapulothoracic protraction angle correlates with the humerothoracic horizontal adduction angle among participants, and (2) the scapulohumeral rhythm of the humerothoracic elevation is not the same as the normal ratio (2:1) observed widely in controlled abductions...
