background and objectives: scapular stabilization and neuromuscular control provide an important parameter to characterize shoulder function during dynamic activities. many studies have confirmed the effect of the loading on scapular position and scapulohumeral rhythm. therefore, the evaluation of stabilizer muscles involvement in scapular asymmetry may assist in the development of clinical exa...

Duplay (1896) was the first investigator to recognize pathologic disorders of extra-articular tissues as possible factors responsible for stiff and painful shoulders. It was his belief that an inflammatory process of the subacromial bursa was the causative agent producing this syndrome. He designated the entity ‘‘scapulohumeral periarthritis.’’ Soon this term came to include a host of heterogen...

BACKGROUND Clinical scapulohumeral tests are lacking post-stroke. OBJECTIVE To test reliability and discriminant validity of clinical scapulohumeral assessments post-stroke. METHODS Following tests were assessed in 57 individuals with stroke (IwS) (subdivided in a low, moderate, high proximal arm function (PAF) group) and 15 healthy controls: (1) Observation of tilting/winging; (2) shoulder...

The present study aimed to compare the shoulder kinematics (3D scapular orientation, scapular angular displacement and scapulohumeral rhythm) of asymptomatic participants under unloaded and loaded conditions during unilateral shoulder elevation in the scapular plane. We utilized a repeated measures design with a convenience sample. Eleven male participants with an age range of 21 to 28 years wi...

Abnormal scapulothoracic mechanics and scapulohumeral rhythm are implicated in shoulder pathologies, including glenohumeral impingement and rotator cuff tears. Upward scapula rotation, specifically asymmetry of scapula motion and associations of patterns through range with injury, was investigated in dominant and non-dominant limbs of nationally ranked junior and Paralympic swimmers during comp...

We assessed the intermediate functional results of eight patients after wide resection of the proximal humerus for malignant bone tumour. We used a free vascularised fibular graft as a functional spacer and a sling procedure to preserve passive scapulohumeral movement. Scapulohumeral arthrodesis was not carried out. Five patients had osteosarcoma, two achondrosarcoma and one a malignant fibrous...

The majority of terrestrial locomotion studies have focused on parasagittal motion and paid less attention to forces or movement in the frontal plane. Our previous research has shown that grizzly bears produce higher medial ground reaction forces (lateral pushing from the animal) than would be expected for an upright mammal, suggesting frontal plane movement may be an important aspect of their ...

The current study aimed to compare the shoulder kinematics (3D scapular orientation, scapular angular displacement and scapulohumeral rhythm) of asymptomatic participants under unloaded and loaded conditions during unilateral shoulder elevation in the scapular plane. We used a repeated-measures design with a convenience sample. Eleven male participants with an age range of 21-28 years with no r...
