OBJECTIVES To establish the test-retest reliability of ultrasound measurements on acromio-humeral distance (AHD) and supraspinatus tendon thickness; and to explore their relationships with shoulder rotational strengths. DESIGN Test-retest observational study. METHODS Thirty-seven individuals (age: 21.5±1.4 years) participated in this study. Twenty-four were University volleyball players wit...

BACKGROUND Archery related injuries, such as shoulder impingement syndrome are caused by repeated motion of the shoulder. The aim of this study was to analyze differences in the shoulder kinematics and the associated muscle activity between archers with shoulder impingement and uninjured archery players. METHODS Thirty male archers, who were divided into an impingement group and an uninjured ...

OBJECTIVE To critically summarize the effectiveness of physio-therapy in patients presenting clinical signs of shoulder impingement syndrome. DESIGN Systematic review. METHODS Randomized controlled trials were searched electronically and manually from 1966 to December 2007. Study quality was independently assessed by 2 reviewers using the Physiotherapy Evidence Database (PEDro) scale. If po...

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...

Subacromial impingement syndrome (SIS) represents a spectrum of pathology ranging from subacromial bursitis to rotator cuff tendinopathy and full-thickness rotator cuff tears. The relationship between subacromial impingement and rotator cuff disease in the etiology of rotator cuff injury is a matter of debate. Both extrinsic compression and intrinsic degeneration may play a role. Management inc...

Down-sloped or hooked acromion morphologies may cause bony encroachment on the soft tissues of the subacromial space, predisposing to shoulder impingement syndrome. Of the latter, a hooked or Type III acromion (T3A) has also been linked to rotator cuff (RC) pathology. However, as bony acromial impingement is typically thought to occur over the age of 40, its occurrence in younger shoulder athle...

Purpose: Sub-acromial impingement syndrome (SAIS) is one of the most common causes shoulder pain and affects joint proprioception. The closed kinetic chain (CKC) exercises with sling are more effective safer than open (OKC) exercises. This study aimed to compare effectiveness OKC total-body resistance (TRX) training on position sense (JPS) in overhead athletes (SIS). Methods: article was a rand...

BACKGROUND Shoulder pain is the third most common musculoskeletal disorder, often affecting people's daily living and work capacity. The most common shoulder disorder is the subacromial impingement syndrome (SIS) which, among other pathophysiological changes, is often characterised by rotator cuff tendinopathy. Exercise is often considered the primary treatment option for rotator cuff tendinopa...
