Muscular patterning can be a contributor of positional posterior shoulder instability. Failure to recognize this pattern may lead to unnecessary surgical treatment with high failure rate. We analyzed the results of a new simple clinical test (hand squeeze test). The test is regarded positive, if during squeezing with the contralateral hand and elevation of the involved arm, in pronation, no pos...

[Purpose] The purpose of this case study was to identify the effects of independent and intensive therapeutic exercise using Proprioceptive neuromuscular facilitation on the size of calcium deposits, pain self-awareness, and shoulder joint function in a patient with calcific tendonitis. [Subject and Methods] The subject was a 42-year-old female patient with calcific tendonitis and acute pain wh...

Superior labrum anterior-posterior lesions are a common cause of shoulder pain. The diagnosis, classification, and indications for surgical intervention remain controversial, and mixed outcomes are associated with primary repair. Given the increasing prevalence of primary superior labrum anterior-posterior repairs in the United States, more surgeons will need to treat patients with poor primary...

BACKGROUND The Western Ontario Shoulder Instability index (WOSI) is a patient-reported outcome measure for patients with shoulder instability. The purpose of this study was to validate the WOSI in a Dutch population by evaluating its structural validity, internal consistency, measurement error, reliability, and construct validity. Floor and ceiling effects were also addressed. METHODS Two coh...

BACKGROUND Numerous techniques for reconstruction of the coracoclavicular ligaments have been developed to treat acromioclavicular joint separations. A new, stronger method to reconstruct the coracoclavicular ligaments using semitendinosus tendon allografts has been previously described. No outcome studies have been published on this new procedure. HYPOTHESIS Reconstruction of the coracoclavi...

Surgical treatment of 3- and 4-part proximal humeral fractures remains challenging. This study retrospectively evaluated functional outcomes of locked plate fixation vs hemi-arthroplasty in 57 patients with 3- and 4-part proximal humerus fractures from 2003 to 2005 with a mean follow-up time of 35 months (range, 15.7-52.7 months). Mean patient age was 56.9 years (range, 29-81.7 years) for the o...

This study has investigated the feasibility of estimating chest acceleration from the pelvic acceleration and shoulder belt forces measured on a vehicle occupant exposed to a frontal crash. The method of estimating chest acceleration is based upon a simple two-mass one-dimensional model of a vehicle occupant in which pelvic acceleration and shoulder belt force are applied as forcing functions. ...

BACKGROUND Few studies have investigated the use of a 3-dimensional gyroscope for measuring the range of motion (ROM) in the impaired shoulder. Reproducibility of digital inclinometer and visual estimation is poor. This study aims to investigate the reproducibility of a tri axial gyroscope in measurement of anteflexion, abduction and related rotations in the impaired shoulder. METHODS Fifty-e...

objectives: the purpose of this study was to investigate the effect of 4-weeks rehabilitation, electrotherapy and kinesiotherapy programs on range of motion shoulder pain in men with idiopathic frozen shoulder. methods & materials: this was a semi experimental study on 18 patient (means±sd age 56.4±6.7 year, height 175.1±5.3 cm, weight 73.1±7.5 kg, history patient 9.2±5.1 month) who referred to...

purpose: altered kinematics of the scapula or scapular dyskinesis (downward rotation, anterior tilt, and protraction) contribute to impingement syndrome by decreasing the subacromial space. given the critical role of scapular position and movement in the function of the shoulder, the aim of this study was to compare scapular position and dyskinesis in individuals with and without rounded should...
