Posterior shoulder tightness (PST) and glenohumeral internal rotation deficit (GIRD) are common physical impairments in overhead sports, such as baseball, cricket and tennis.(1-4)) PST is clinically measured by passive shoulder horizontal adduction with scapula stabilized in supine or side lying.(5),(6)) GIRD is generally characterised as concurrent deficits of internal rotation (IR) and total arc of motion in dominant side.(7),(8)) Although the mechanisms of PST and GIRD are not clear, it is speculated that they derive from tight posterior glenohumeral capsule and posterior muscles, such as posterior deltoid, infraspinatus and teres minor muscles...

BACKGROUND: Pectoralis minor (PM) tightness has been linked to pain and dysfunction of the shoulder joint secondary to anterior tilt and internal rotation of the scapula, thus causing secondary impingement of the subacromial space. PURPOSE: To describe outcomes pertaining to nonoperative and operative treatment via surgical release of the PM tendon for pathologic PM tightness in an active population. STUDY DESIGN: Case series; Level of evidence, 4...

BACKGROUND: High level throwing performance requires the development of effective muscle activation within shoulder girdle muscles particularly during forceful internal rotation (IR) motions. STUDY DESIGN: Controlled Laboratory Descriptive Study. PURPOSE: To investigate activation pattern of 16 shoulder girdle muscles/muscle sub-regions during three common shoulder IR exercises. METHODS: EMG was recorded in 30 healthy subjects from 16 shoulder girdle muscles/muscle sub-regions (surface electrode: anterior, middle and posterior deltoid, upper, middle and lower trapezius, serratus anterior, teres major, upper and lower latissimus dorsi, upper and lower pectoralis major; fine wire electrodes: supraspinatus, infraspinatus, subscapularis and rhomboid major) using a telemetric EMG system...

BACKGROUND: The ability of injection of corticosteroids into the subacromial space to relieve pain ascribed to rotator cuff tendinosis is debated. The number of patients who have an injection before one gets relief beyond what a placebo provides is uncertain. QUESTIONS/PURPOSES: We asked: (1) Do corticosteroid injections reduce pain in patients with rotator cuff tendinosis 3 months after injection, and if so, what is the number needed to treat (NNT)? (2) Are multiple injections better than one single injection with respect to pain reduction at 3 months? METHODS: We systematically searched seven electronic databases for randomized controlled trials of corticosteroid injection for rotator cuff tendinosis compared with a placebo injection...

OBJECTIVE: The aim was to assess diagnostic accuracy of 15 shoulder special tests for rotator cuff tears. DESIGN: From February 2011 to December 2012, 208 participants with shoulder pain were recruited in a cohort study. RESULTS: Among tests for supraspinatus tears, Jobe test had a sensitivity of 88% (95% confidence interval [CI], 80%-96%), specificity of 62% (95% CI, 53%-71%), and likelihood ratio of 2.30 (95% CI, 1.79-2.95). The full can test had a sensitivity of 70% (95% CI, 59%-82%) and a specificity of 81% (95% CI, 74%-88%)...

BACKGROUND: The exact role of platelet-rich plasma (PRP) in rotator cuff tendon reconstruction remains unclear. PURPOSE/HYPOTHESIS: This study investigated whether an intraoperative pure PRP injection, compared with a local anesthetic injection, improves patient-reported outcomes at 3 and 6 months after arthroscopic rotator cuff repair. The hypothesis was that pure PRP improves patient-reported outcomes (Oxford Shoulder Score [OSS]) at 3 and 6 months after surgery and has the same pain-reducing effect compared with a postoperative subacromial local anesthetic (ropivacaine) injection...

BACKGROUND: Several biomechanical studies have shown that the acromioclavicular (AC) ligament prevents posterior translation of the clavicle in the horizontal plane. In anatomy textbooks, however, the AC ligament is illustrated as running straight across the AC joint surface. HYPOTHESIS: The AC ligament does not run straight across the joint surface, and the configuration of the AC ligament may vary. STUDY DESIGN: Descriptive laboratory study...

UNLABELLED: The incidence of rotator cuff tears increases with age, with full-thickness rotator cuff tears present in approximately 25% of individuals in their sixties, and more than 50% of those in their eighties. While surgery is considered an effective treatment, recurrent tears at the insertion site are common, especially with degenerative tears, which are frequent in the older population. More recently, there has been increasing interest in exercise rehabilitation and physical therapy as a means to manage partial and full thickness tears of the rotator cuff by addressing weakness and functional deficits...

BACKGROUND: There are few level 1 or 2 evidence studies that examine rehabilitation after rotator cuff repair. Pulleys have been used in postoperative shoulder rehabilitation with the intention of improving range of motion and developing strength. There is a concern that the use of pulleys in rehabilitation of rotator cuff repairs may contribute to excessive scapular motion (scapular substitution) and potentially inferior outcomes. HYPOTHESIS: Rotator cuff repair patients treated with pulley exercises would have increased scapular substitution and inferior patient-determined outcome scores, range of motion, and strength compared with patients treated with an alternative rehabilitation program without pulleys...

BACKGROUND: Some patients with rotator cuff tears feel pain without functional limitation, whereas others show a decrease in range of motion. To investigate this distinction, the scapulohumeral rhythm was used to conduct a functional evaluation of shoulder joints' coordination. The objective was to characterize patients according to their active range of motion without pain and their scapulohumeral rhythm compared with healthy individuals. MATERIALS AND METHODS: Fourteen patients with rotator cuff tears and 14 healthy individuals were set up with 35 reflective markers on the trunk and upper limb tracked by an optoelectronic system to measure the scapulohumeral rhythm...
