For kinematic studies of the shoulder, electromagnetic sensors are commonly placed on the humerus, scapula, and trunk. The trunk sensor is used to describe humeral and scapular kinematics with respect to the trunk. There are two common trunk sensor placements, the sternum or third thoracic vertebrae (T3). It is currently unclear if placement of the trunk sensor affects kinematics, making it difficult to compare data across studies. The purpose of this study was to compare two trunk sensor placements (T3 and sternum) on trunk and scapular kinematics during arm elevation...

Adult overhead athletes without a history of shoulder injury show scapular adaptations. There is a lack of detailed assessment of scapular kinematics in junior overhead athletes. This study aims to investigate three-dimensional scapular kinematics in junior overhead athletes. We recruited a total of 20 junior tennis players and 20 healthy children without participation in any overhead sports in this study. Bilateral scapular kinematic data were recorded using an electromagnetic tracking device for scapular plane glenohumeral elevation...

BACKGROUND: No clear trend has emerged from the literature regarding three-dimensional (3D) translations of the humerus relative to the scapula in shoulders with rotator cuff tears (RCTs). The purpose of this study was to evaluate the kinematics of RCT shoulders using 3D-to-two-dimensional (2D) model-to-image registration techniques. METHODS: Dynamic glenohumeral kinematics during scapular plane abduction and axial rotation were analyzed in 11 RCT patients and 10 healthy control subjects...

OBJECTIVES: To compare the kinematics and electromyography of the periscapular muscles in swimmers before and after a 3-min maximal effort test. PARTICIPANTS: 16 competitive swimmers. MAIN OUTCOME MEASUREMENTS: Infrared cameras were used to record kinematics in the scapular plane in synchronization with the electromyography system. RESULTS: There was an increase in internal rotation in all angles (p < 0.05), an increase of the anterior tilt, with 120° of elevation (p = 0...

BACKGROUND: Scapular dyskinesis is an alteration in normal scapular position and motion. Some researchers believe that altered kinematics of the scapula subsequent to dysfunction or weakness of scapular stabilizing muscles contributes to impingement syndrome. Scapular muscle exercises are included in the rehabilitation of patients with subacromial impingement syndrome and scapular dyskinesis because the muscular system is one of the major contributors of scapular positioning both at rest and during shoulder movement, but there is considerable uncertainty relating to the relative effectiveness of such approaches on changing scapular position and motion...

STUDY DESIGN: Crossover repeated-measure design. INTRODUCTION: Scapular dyskinesis rehabilitation programs that focus on inhibiting upper trapezius (UT) and activating the lower trapezius (LT) may assist in restoring scapular movements. We hypothesized that taping may be able to normalize scapular movements and associated muscular recruitment. PURPOSE OF THE STUDY: The purpose of this study was to investigate the immediate effects of kinesio taping over trapezius on scapular kinematics and muscular activation in different dyskinesis patterns...

BACKGROUND: Contractile tissue plays an important role in mobility deficits in frozen shoulder (FS). However, no study has assessed the effect of the muscle release technique on the muscle activation and kinematics in individuals with FS. The purposes of this study were to assess the differences in shoulder muscle activity and kinematics between the FS and asymptomatic groups; and to determine the immediate effects of muscle release intervention in the FS group. METHODS: Twenty patients with FS and 20 asymptomatic controls were recruited...

The purpose of this study is to evaluate scapular movements by the three-dimensional electromagnetic system during shoulder elevation in FSHMD patients, and to compare the results with healthy individuals. 10 patients with FSHMD and 10 healthy individuals were included in the study. Scapular anterior-posterior tilt, upward-downward rotation and internal-external rotation at 30°, 60° and 90° were evaluated using the three-dimensional electromagnetic system during the elevation of the upper limbs in the scapular plane...

CONTEXT: Previous literature has theorized that alterations in shoulder physical characteristics are present in wheelchair athletes and contribute to shoulder pain and injury. Limited empirical evidence is present that evaluates the effectiveness of a shoulder injury prevention program focusing on improving these altered characteristics. OBJECTIVE: To evaluate the effectiveness of a 6-week intervention program at improving characteristics that increases the risk of developing pain or shoulder injury...

Scapular kinematics are important indicators of dyskinesis, often suggesting underlying shoulder pathology, but the influence of sex is unknown. This study's objective was to examine scapular kinematics in healthy males and females. Positions of surface-mounted reflective markers were tracked during arm elevation movements in 0°/30°/40°/60°/90°/120° planes. Scapulothoracic rotations (protraction/retraction, medial/lateral rotation, posterior/anterior tilt) were calculated. ANOVA analysis evaluated main and interaction effects of sex, plane, phase, elevation angle...

OBJECTIVE: The purpose of this study was to describe the 3-dimensional deformities of midshaft clavicle fractures, which had been treated nonoperatively, using computed tomography (CT) surface matching. METHODS: Twenty-one patients with unilateral midshaft clavicle fracture, who had been treated nonoperatively, were enrolled and evaluated retrospectively. The 3-dimensional deformity of the fractured clavicle was evaluated by CT surface matching. CT scans of 21 age- and sex-matched patients with initial traumatic shoulder dislocation or proximal humeral fracture were enrolled as a control group, and the differences in 3-dimensional deformities and lengths of the clavicles between the fracture group and the control group were evaluated...

BACKGROUND: The global range of motion of the arm is the result of a coordinated motion of the shoulder complex including glenohumeral (GH), scapulothoracic, sternoclavicular and acromioclavicular joints. METHODS: This study is a non-systematic review of kinematic patterns in degenerated shoulders. It is a based on our own research on the kinematics of the shoulder complex and clinical experience. RESULTS: For patients with subacromial impingement syndrome without rotator-cuff tears, most kinematic studies showed a small superior humeral translation relative to the glenoid and decreased scapular lateral rotation and posterior tilt...

BACKGROUND: There is limited research to demonstrate how scapular kinematics and shoulder-related physical characteristics are affected in water-polo players, who undertake swimming and repetitive throwing activity. The aim of this study was to investigate possible adaptations in the three- dimensional scapular kinematics and in glenohumeral internal rotation, external rotation range of motion and shoulder posterior-capsule tightness in water-polo players. METHODS: Fourteen water-polo players and 14 asymptomatic volunteers participated in the study...

BACKGROUND: Although hydrotherapy is widely used to treat women with fibromyalgia, no studies have investigated the effects of this intervention on scapular kinematics in this population. This study verified the effectiveness of a hydrotherapy program on scapular kinematics, pain and quality of life in women with fibromyalgia. METHODS: Twenty women completed the study and performed three evaluations before treatment (to establish a baseline), and two other evaluations (after 8 and 16weeks of hydrotherapy) at the end of treatment...

OBJECTIVES: Water polo is a popular water-based contact sport that involves swimming, throwing and defending. Cumulatively, these repetitive overhead activities are thought to increase the risk of shoulder injury and, subsequently to affect players' physical conditioning as well as team performance. The purpose of this review was to examine available evidence relating to shoulder injury rates and risk factors for shoulder injury in water polo. DESIGN: Systematic review METHODS: CINAHL, AUSPORT, Pubmed, Pedro and SPORTDiscus databases were searched for original research papers using the predefined terms ("water polo") AND (shoulder OR glenohumeral* OR arm OR "upper limb")...
