Low back and neck and shoulder pain in members and non-members of adolescents' sports clubs : the Finnish Health Promoting Sports Club (FHPSC) study

2016

Background The objective of this study was to investigate the prevalence of self-reported low back pain (LBP) and neck and shoulder pain (NSP), and the related factors in members and non-members of adolescents’ sports clubs. Methods This cross-sectional study was based on surveys of 14–16-year-olds as a part of the Finnish Health Promoting Sports Club (FHPSC) Study. The surveys on self-reported health behaviours, injuries, and musculoskeletal health were conducted among sports club members (n = 962) and non-members (n = 675). Binary logistic regression analysis was applied to study the associations between dependent variables of LBP and NSP, and the independent factors. Results The prevalen…

A new method to evaluate the influence of the glenosphere positioning on stability and range of motion of a reverse shoulder prosthesis

2019

Abstract Purpose Shoulder instability and reduced range of motion are two common complications of a total reverse shoulder arthroplasty. In this work, a new approach is proposed to estimate how the glenoid component positioning can influence the stability and the range of motion of a reverse shoulder prosthesis. Materials and methods A standard reverse shoulder prosthesis has been analysed. To perform virtual simulation of the shoulder-prosthesis assembly, all the components of the prosthesis have been acquired via a 3D laser scanner and the solid models of the shoulder bones have been reconstructed through CT images. Loads on the shoulder joint have been estimated using anatomical models d…

Redesign of a reverse shoulder prosthesis: Kinematic and mechanical study

2014

In this work a commercial reverse shoulder prosthesis has been redesigned to improve performances in terms of range of movements of the implant and stability to dislocation. A kinematic and mechanic study has been performed using a realistic solid model of the prothesised shoulder: in particular, all the components of the prosthesis have been acquired via a 3D laser scanner and inserted in a virtual humerus-glenoid system by reproducing the common surgical procedure. The final model has been used to measure the maximum angles of abduction and rotation of the arm and the shear forces that cause dislocation. Modifications proposed to the commercial prosthesis are: a different orientation of t…

Approccio integrato tra il trattamento riabilitativo e farmacologico nella frozen shoulder

2007

La struttura del complesso anatomico della spalla è caratterizzata da un'ampia escursione articolare. LA nostra esperienza si è basata su uno studio preliminare di 21 pazienti; tutti prsentavano una stadiaizone di patologia di grado lieve/ moderata. Dall'analisi dei dati si evince come il trattamento combinato farmacologico/ riabilitativo possa fornire risultati migliori rispetto al solo trattamento farmacologico.

Comments to the paper "do we really need new medical information about the Turin Shroud?".

2015

Abstract Following the interesting arguments raised in a recent letter to the editor, about a paper recently published in this journal, the authors are happy to take a cue from them to clarify some facts that have not been sufficiently treated for space. After a description of the methods used, arguments regarding a blunt trauma on the right shoulder with consequent dislocation, the position of the hands on the pubis with brachial plexus injury, and the wrist nailing that caused retracted thumbs are discussed in detail.

Numerical study of the components positioning influence on the stability of a reverse shoulder prosthesis

2014

Aim of this paper is to setup a novel procedure able to analyze performances of a reverse shoulder prosthesis when different geometrical configurations are assumed. Nowadays, such a prosthesis is widely used but, because of its novelty, data in literature give poor information about performances and limits to its applicability. The activity has been divided into the following steps. At the beginning the shape of the prosthesis has been digitally acquired via a 3D scanner. Then, CAD models of all prosthetic components have been geometrically optimized in a way to obtain final entities suitable for numerical simulations. After that, CAD assemblies have been created between prosthetic componen…

Adhesive capsulitis of the shoulder: laser CO2 vs intra-articular injections

2012

Analysis of our data shows that the functional rehabilitation associated with the CO2 laser causes a greater reduction in pain, better recovery of joint ROM and increase in muscle strength compared to treatment associated with injections of corticosteriods

Rehabilitation following injury of the rotator cuff

2003

The main aim of this paper is to compare two diffrent rehabilitation tecniques for treatment of the shoulder joint following injury of the rotator cuff. The seriousness of the pathology means patients generally have to endure a considerable period during wich use of the joint in question is impossible

On the history of torsional stress concentrations in shafts: From electrical analogies to numerical methods

2014

This article proposes a retrospective on experimental and numerical methods developed throughout the past century to solve the torsion problem in shafts, with particular emphasis on the determination of shear stress concentration factors in discontinuities of typical use in shaft design. This article, in particular, presents the theory and related solutions distinguishing between two classes of geometries: shafts with constant cross section and axisymmetric shafts with variable diameter. Emphasis is given to approaches based on physical analog methods and, in particular, those based on electrical analogies proposed since about 1925. Experimental methods based on structural physical models …
