BACKGROUND AND PURPOSE Several factors such as posture, muscle force, range of motion, and scapular dysfunction are commonly believed to contribute to shoulder impingement. The purpose of this study was to compare 3-dimensional scapular kinematics, shoulder range of motion, shoulder muscle force, and posture in subjects with and without primary shoulder impingement syndrome. SUBJECTS Forty-fi...

UNLABELLED There is a growing body of literature associating abnormal scapular positions and motions, and, to a lesser degree, clavicular kinematics with a variety of shoulder pathologies. The purpose of this manuscript is to (1) review the normal kinematics of the scapula and clavicle during arm elevation, (2) review the evidence for abnormal scapular and clavicular kinematics in glenohumeral ...

Abnormal scapular kinematics and associated muscle function presumably contribute to shoulder pain and pathology. An understanding of scapular kinematic and electromyographic profiles in asymptomatic individuals can provide a basis for evaluation of pathology. The purpose of this study was to describe normal three-dimensional scapular orientation and associated muscle activity during humeral el...

BACKGROUND Appropriate motion of the scapula is important for dynamic positioning of the glenoid during humeral elevation. A number of studies have described the typical scapular kinematics during humeral elevation in adults. However, children and adults may have differences in scapulothoracic musculature and scapular osteology. To our knowledge, no study has been performed examining scapular k...

The purpose of our study was to establish criterion-related validity and repeatability of a shoulder biomechanics testing protocol involving an electromagnetic tracking system (Flock of Birds [FoB]). Eleven subjects completed humeral elevation tasks in the sagittal, scapular, and frontal planes on two occasions. Shoulder kinematics were assessed with a digital inclinometer and the FoB. Intrases...

STUDY DESIGN A cross-sectional control-matched study in adolescents with idiopathic scoliosis (IS). OBJECTIVE To evaluate whether subjects with IS had shoulder dysfunction and associated impairment in shoulder kinematics and muscular activation. SUMMARY OF BACKGROUND DATA Evidence indicates that shoulder kinematics are related to shoulder pain and dysfunction. Despite the degree of morbidit...

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...

The scapula functions as a bridge between the shoulder complex and the cervical spine and plays a very important role in providing both mobility and stability of the neck/shoulder region. The association between abnormal scapular positions and motions and glenohumeral joint pathology has been well established in the literature, whereas studies investigating the relationship between neck pain an...

CONTEXT Proper scapulothoracic motion is critical for the health and function of the shoulder and represents a principal focus in the rehabilitation setting. Variants of the traditional push-up are used frequently to help restore proper scapular kinematics. To date, substantial research has focused on muscle activation levels of rotator cuff and scapular-stabilizing musculature, whereas a deart...
