Abstract:

Both clinical and biomechanical problems affecting the shoulder joint suggest that investigators should study force transmission into and out from the scapula. To analyze force transmission between the humeral head and the glenoid, one must know the position of the glenoid. Studies have analyzed the position of the scapula from the positions of three palpable points, but the position of the glenoid relative to three palpable points has not been studied. Dry scapulae () were subjected to X-rays and a critical angle, (which relates the plane determined by the three palpable points on the scapula

Abstract:

The scapula plays a critical role in the association between the upper extremity and the axial skeleton. Fractures of the scapula account for 0.4% to 1% of all fractures and have an annual incidence of approximately 10 per 100,000 inhabitants. Scapular fractures typically result from a high-energy blunt-force mechanism and are often associated with other traumatic injuries. The present review focuses on the presentation, diagnosis, and treatment of fractures of the scapula. Indications for surgical treatment of glenoid fossa, scapular neck, and scapular body fractures are presented in detail.

Abstract:

The scapulothoracic articulation is a sliding junction between the deep aspect of the scapula and thoracic rib cage at the levels of ribs 2 through 7. Motion at this articulation is dynamically stabilized by a variety of muscular attachments, allowing for controlled positioning of the glenoid to assist in glenohumeral joint function. A thorough understanding of the complex anatomic relationships, including the various muscles, and bursa, is critical to the evaluation of patients presenting with scapulothoracic disorders. The snapping scapula syndrome is caused by either osseous lesions or scap

Acromion marker cluster (AMC) methods have been shown to accurately track scapula motion during humeral elevation below 90°, however, their accuracy has not been assessed in shoulder girdle motion such as clavicle protraction, retraction, elevation, and depression independent of humeral movement. The aim of this study was to examine the reliability and validity of the AMC method to record scapula orientation at end range clavicle protraction, retraction, elevation, and depression.

Scapular abduction and upward tilt of the scapula were measured with a ruler and a beveled prOTRactor in four test positions. The data showed that multiple measurements were needed due to the high variability of scapular positioning across subjects. The most reliable and least variable of the four test positions was the quadruped position.

More importantly, we discover that not only user orientations but also smartphone carrying positions may affect signal attenuations caused by human body greatly. Therefore, we propos

Abstract:

Baikal-GVD is a cubic kilometer-scale neutrino telescope currently under construction in Lake Baikal. The detector’s components are mobile and may drift from their initial coordinates or change their spatial orientation. This introduces a reconstruction error, particularly a timing error for PMT hits. This problem is mitigated by a combination of a hydroacoustic positioning system and per-component acceleration and orientation sensors. Under regular conditions, the average positioning accuracy for a GVD component is estimated to be less than 13 cm.

Abstract:

Category: Bunion Introduction/Purpose: Studies have demonstrated that patients with hallux valgus (HV) deformities have increased mobility in the first tarsometatarsal (TMT) joint. Anatomical factors widely considered to play a role in the instability are shape and frontal plane orientation of the joint. An oblique rather than horizontal orientation of the articular surfaces and a round shape, rather than a flat shape, are believed to predispose to the deformity. The purpose of this study was to assess whether the shape and angulation of the first TMT joint are affected by the positioning of t

Abstract:

Introduction: An important skill for orientation and mobility (O&M) specialists to have is to monitor clients appropriately when they are learning to cross intersections. Techniques books provide some suggestions for positioning during street crossings, but no research has been conducted about consensus or priorities for making appropriate decisions on positioning. The purpose of this study was to investigate general positioning decisions using visual monitoring techniques. Method: A total of 234 participants (practicing O&M specialists, preservice O&M students, and O&M univers

Abstract:

Purpose – The purpose of this paper is to revise the concept of positioning to differentiate between fundamental approaches to it and chart a scheme of schools of positioning. Design/methodology/approach – An extensive literature review traces the roots and evolution of the concept. Two approaches to positioning are explored and related to the paradigms of market and brand orientation. Based on current theory and practice, different schools of positioning are identified and categorized along a market- and brand-orientation spectrum. Metaphors differentiate schools of positioning, illustrated b
