BACKGROUND Arm elevation is composed of glenohumeral and scapulothoracic motion. Many reports have addressed changes of scapular position across a spectrum of shoulder disease. However, no study has examined changes in scapular position after reverse total shoulder arthroplasty (RTSA). The purpose of this study was to evaluate the changes in scapular position after RTSA compared to patients' co...

We investigated the relationship between free-throw accuracy and performance variables among fourteen elite male wheelchair basketball players. Participants performed 20 free-throws. Basketball were phases of pre-shoot routine: (a) time taken, (b) minimum angle when taking ball back, (c) at release, (d) angular displacement during forward arm swing, (e) velocity release on elbow, shoulder, hip....

Estimating the elbow angle using shoulder data is very important and valuable in Functional Electrical Stimulation (FES) systems which can be useful in assisting C5/C6 SCI patients. Much research has been conducted based on the elbow-shoulder synergies.The aim of this study was the online estimation of elbow flexion/extension angle from the upper arm acceleration signals during ADLs. For this, ...

purpose: to evaluate ophthalmologists’ sitting position during ocular examination and surgery and to evaluate any correlation between musculoskeletal disorders and mean work time.   methods: this cross-sectional study was performed on ophthalmologists in isfahan, iran in different occupational positions including the office, during slitlamp examination and in the operating room. the evaluation ...

K e y w o r d s Sprengel’s deformity, Congenital elevation of the scapula, Surgery, Grading system INTRODUCTION Congenital elevation of the scapula, i.e., scapula alta is characterised by a various degree of scapular dysplasia, smaller size of the affected scapula as compared to the healthy side, rotation of the distal angle medially and active elevation of the arm is more or less reduced . The...

[Purpose] The purpose of this study was to investigate the effect of the shoulder flexion angle on the muscle activities of the upper extremities when performing the push-up plus exercise (PUPE) on an unstable surface with the forearm in the external rotation position. [Subjects] The subjects were conducted on 15 normal male adults. [Methods] A sling device was used for the unstable surface, an...

[Purpose] The purpose of this study was to compare the upper, middle, and lower trapezius muscles' activity in the different planes of shoulder elevation. [Subjects] Twenty male subjects volunteered for this study. [Methods] Surface electromyographic (EMG) activity for each of the three regions of the trapezius muscles in the three different planes of elevation were collected while the particip...

Diabetes metabolic disorders can lead to changes in connective tissue and adhesive capsulitis (AC) is one of the most common complications that occour with diabetes where it defined as pain restriction glenohumeral joint capsule causes limitation ROM shoulder. Physiotherapy has many modalities proved their role improving symptoms AC so this study was aiming Know which more effective symptoms: (...

BACKGROUND The etiology of rotator cuff disease is age related, as documented by prevalence data. Despite conflicting results, growing evidence suggests that distinct scapular morphologies may accelerate the underlying degenerative process. The purpose of the present study was to evaluate the predictive power of 5 commonly used radiologic parameters of scapular morphology to discriminate betwee...
