BACKGROUND It is important to deal with the scapula when developing rehabilitation strategies for the shoulder complex. This requires clinical measurement tools that are readily available and easy to apply and which provide a reliable evaluation of scapula motion. AIM To determine the reliability of the Plurimeter-V gravity inclinometer for the measurement of scapular upward rotation position...

BACKGROUND Many prior studies have evaluated shoulder motion, yet no three-dimensional analysis comparing the combined clavicular, scapular, and humeral motion during arm elevation has been done. We aimed to describe and compare dynamic three-dimensional motion of the shoulder complex during raising and lowering the arm across three distinct elevation planes (flexion, scapular plane abduction, ...

BACKGROUND Pain and loss of function are cardinal symptoms associated with Subacromial impingement syndrome (SIS), while the presence and magnitude of deficits in strength and range of motion (ROM) are largely undescribed in non-athletic patients with SIS. Moreover, the relevance of impairments in strength and ROM to patient-reported shoulder function is not well described, even though testing ...

BACKGROUND Dysfunction in the kinetic chain caused by poor scapula stabilization can contribute to shoulder injuries and Shoulder Impingement Syndrome (SIS). The purpose of this study was to compare the effectiveness of two treatment approaches scapular stabilization based exercise therapy and physical therapy in patients with SIS. METHODS The study is a randomized clinical trial in which 68 ...

OBJECTIVE This study compares the effect of wrist immobilization with non-immobilization on shoulder abduction, shoulder flexion, and shoulder rotation during feeding. METHOD Twenty right-hand-dominant participants with no upper-extremity dysfunction performed a controlled feeding activity under 2 separate wrist conditions: (1) while wearing a static wrist orthosis and (2) with the wrist not ...

BACKGROUND Supraspinatus deficiency is the most frequent and important problem associated to rotator cuff pathologies. It reduces shoulder stability and can lead to osteoarthritis. The goal of this study was to develop a numerical model of the shoulder to analyse the biomechanical consequences of this pathology. METHODS A 3D finite element model of the shoulder was developed from a normal cad...

Shoulder abduction fatiguability has been measured using a hand held myometer in normal subjects and patients with peripheral neuromuscular diseases. An index of fatiguability was based on the decline in force over a series of ten maximum voluntary contractions performed in under a minute. The technique was repeatable and well tolerated. Patients with myasthenia, mitochondrial myopathy and moto...

Focal posttraumatic shoulder dystonia is a rare and not easily identifiable entity. Its true pathophysiologic nature, predisposing factors, and disease course remain debatable.This article describes a rare case of a 40-year-old man with late symptoms of focal shoulder dystonia after peripheral trauma of his left shoulder girdle. The shoulder was indirectly injured from the impact of a fall off ...

UNLABELLED The purpose of the current study was to investigate the relation between shoulder morbidity (pain and range of motion), and the function of the spinal accessory nerve after neck dissection. Identifying dysfunction of the nerve gives insight in the mechanisms of post-operative shoulder complaints. In total 112 patients after neck dissection (73 males/39 females), mean (SD) age 61 (13)...

OBJECTIVE To evaluate the outcome of modified Quad procedure in preteen and teen patients with brachial plexus birth palsy. BACKGROUND We have previously demonstrated a significant improvement in shoulder abduction, resulting from the modified Quad procedure in children (mean age 2.5 years; range, 0.5-9 years) with obstetric brachial plexus injury. METHODS We describe in this report the out...
