The human shoulder complex is perhaps the most complicated joint in the human body being comprised of a set of three bones, muscles, tendons, and ligaments. Despite this anatomical complexity, computer graphics models for motion capture most often represent this joint as a simple ball and socket. In this paper, we present a method to determine a shoulder skeletal model that, when combined with ...

T he glenohumeral joint is the most mobile and one of the most frequently dislocated joints in the human body. Before skeletal maturity, shoulder dislocations are less frequent, and shoulder trauma more often results in fracture through the proximal humeral physis. In a recent epidemiologic study, Zacchilli and Owens found that shoulder dislocations follow a bimodal distribution, with 46.8% occ...

results totally, 20 patients completed the study. the cms and pain scores significantly improved after the block. conclusions the use of the modified lateral ssnb of feigl significantly reduces pain and increases shoulder function, in chronic shoulder pain. patients and methods patients were evaluated using the constant-murley score (cms) and number rating scale values for pain. the ssn was blo...

Touch is the most intimate and inherently private human sense and provides the potential for discrete, low social weight human computer interaction. This paper presents initial research findings on issues of integrating a vibrotatcitle display and support electronics into a standard clothing insert, the shoulder pad. Research on construction methods is presented along with a discussion of the m...

displaced fracture of the acromion without associated shoulder injury occurs rarely. a 31-year-old gentleman presented with an isolated acromion fracture resulting from a direct trauma to the top of his left shoulder. open reduction and internal fixation using multiple pins was performed and the fracture was closed without complications. the patient achieved excellent shoulder function and rank...

–In virtual human modeling, the shoulder is usually composed of clavicular, scapular and arm segments related by rotational joints. Although the model is improved, the realistic animation of the shoulder is hardly achieved. This is due to the fact that it is difficult to coordinate the simultaneous motion of the shoulder components in a consistent way. Also, the common use of independent 1-DOF ...

During multijoint limb movements such as reaching, rotational forces arise at one joint due to the motions of limb segments about other joints. We report the results of three experiments in which we assessed the extent to which control signals to muscles are adjusted to counteract these "interaction torques." Human subjects performed single- and multijoint pointing movements involving shoulder ...

This paper presents the state-of-the-art on the 3D functional modelling of the hip and shoulder, and analyses critical aspects on this subject. For the accurate human hip and shoulder model, we need to pay a careful consideration to the correct material properties about organs (bones, cartilages, ligaments, muscles, and skins) and joint mechanics. The survey of functional modelling and our prop...

The shoulder is the most unstable joint in the human body. Traumatic anterior instability of the shoulder is a common condition, which, especially in young patients, is associated with high recurrence rates. The effectiveness of non-surgical treatments when compared to surgical ones is still controversial. The purpose of this study was to review the literature for current concepts and updates r...

BACKGROUND Shoulder pain and dysfunction are common after oncologic neck dissection for head and neck cancer (HNC), due to traction, compression, and devascularization injuries to the spinal accessory nerve (SAN). Shoulder pain and dysfunction can hinder postoperative rehabilitation and hygiene, activities of daily living (ADLs), and return to work after treatment for HNC. Due to the rising inc...
