INTRODUCTION Neck injuries are common in high performance combat pilots and have been attributed to high gravitational forces and the non-neutral head postures adopted during aerial combat maneuvers. There is still little known about the pathomechanics of these injuries. METHODS Six Royal Australian Air Force Hawk pilots flew a sortie that included combinations of three +Gz levels (1, 3, and ...

Background: To retrospectively review surgical outcomes of prospectively collected data on a series of patients whounderwent revision of a type II SLAP repair to arthroscopic biceps tenodesis due to an unsuccessful outcome.Methods: A retrospective review was performed on a cohort of patients who underwent arthroscopic biceps tenodesisfor a failed type II SLAP repair from 2010 ...

Everyday actions invariably consist of a combination of discrete and rhythmic elements within or across joints. The study investigated constraints arising from the co-occurrence of the two actions in a two-joint task and how endpoint trajectories are shaped due to these action elements at the joint level. The task consisted of an elbow oscillation in the plane that was to be merged with a fast ...

The purpose of this study was to examine kinesthesia in normal (uninjured) shoulders and in shoulders with a history of glenohumeral joint dislocations. Both shoulders of 10 healthy subjects and 8 subjects with a history of unilateral anterior dislocation were tested for accuracy of angular reproduction, threshold to sensation of movement, and end-range reproduction using a motor-driven shoulde...

The high prevalence of shoulder-related dysfunction has focused increased attention on functional activity assessment. This study (1) tested the reliability of three-dimensional shoulder complex movements during four functional tasks representing different levels of task difficulty, (2) characterized the four functional tasks, and (3) examined the relationships between age and shoulder movement...

BACKGROUND Following shoulder arthroplasty, any well-planned rehabilitation program should include muscle strengthening. However, it is not always clear how different external loads influence shoulder kinematics in patients with shoulder prostheses. The objective of this study was to describe shoulder kinematics and determine the contribution of the scapulothoracic joint to total shoulder motio...

INTRODUCTION Extended manual wheelchair use has been associated with repetitive strain injuries in the shoulder and has been identified as a contributing factor to upper limb pain experienced by manual wheelchair users with spinal cord injury (SCI) [1]. Due to the nature of their SCI, individuals with tetraplegia (formerly quadriplegia) may be at an even greater risk for developing shoulder inj...

OBJECTIVE To evaluate the effect of linearly polarized near-infrared irradiation (Super Lizer) combined with aerothermotherapy in the treatment of patients with frozen shoulder and diabetes. METHODS Eighty-four diabetic patients with frozen shoulder were randomized into 3 groups to receive a 20-day treatment with drug therapy and shoulder exercise (control group), daily linearly polarized nea...
