Cross-cultural adaptation and validation of the French version of the Knee injury and Osteoarthritis Outcome Score (KOOS) in knee osteoarthritis pati…
2008
Udgivelsesdato: 2008-Apr OBJECTIVE: To adapt the Knee injury and Osteoarthritis Outcome Score (KOOS) into French and to evaluate the psychometric properties of this new version. METHODS: The French version of the KOOS was developed according to cross-cultural guidelines by using the "translation-back translation" method to ensure content validity. KOOS data were then obtained in patients with symptomatic knee osteoarthritis (OA). The translated questionnaire was evaluated in two knee OA population groups, one with no indication for joint replacement (medicine), and the other waiting for joint replacement (surgery). The psychometric properties evaluated were feasibility: percentage of respon…
Generation of narrowband antisymmetric lamb waves using a formed laser source in the ablative regime
2007
A formed laser source, using a four-element lenticular array, is used in the ablative regime to generate select, narrowband, acoustic plate waves. The arrangement of the array produces acoustical signals that have frequencies compatible with the response of the broadband capacitive air-coupled transducer used in this study. A simplified concept is presented to explain the effect of a line array source on the frequency content of acoustic waves. The analytical model for a point pulse surface displacement is derived from the point load solution to Lamb's problem. The point pulse displacement elements of a line array source are summed mathematically, taking into account all applicable propagat…
Patients' narratives of patient education in physiotherapy after total hip arthroplasty.
2019
Abstract Objective The aim of this study was to explore patients' narratives of patient education in physiotherapy after a total hip arthroplasty (THA). Method The data was collected via open thematic interviews from ten patients who had had a primary THA. The interviews were analysed using a qualitative, narrative method. Results Three story models of patient education in physiotherapy were identified: Supportive patient education in physiotherapy, Co-operative patient education in physiotherapy and Contradictory patient education in physiotherapy. The emphasis of narration in the first story model was on the trust in the guidance, functioning interaction in the second and insufficient pat…
Les réseaux de transport à grande vitesse en France : construction et apports d'un système d'information géo-historique
2016
The originality of this Historical Geographic Information System (SIGH) is that it is focuses on various transport networks (road and railway) at several temporal scale (from 1975 to 2010). The corresponding spatial network offers the possibility to generate spatial and temporal matrices across France, at different dates. These possibilities open important spatial analysis perspectives. They allow for example to assess the effect of investments in high-speed transport supply on the durations of intercity trips, also multiple opportunity in the field of Regional Science and Complex Systems analysis.
Joint image and motion reconstruction for PET using a B-spline motion model.
2012
We present a novel joint image and motion reconstruction method for PET. The method is based on gated data and reconstructs an image together with a motion function. The motion function can be used to transform the reconstructed image to any of the input gates. All available events (from all gates) are used in the reconstruction. The presented method uses a B-spline motion model, together with a novel motion regularization procedure that does not need a regularization parameter (which is usually extremely difficult to adjust). Several image and motion grid levels are used in order to reduce the reconstruction time. In a simulation study, the presented method is compared to a recently propos…
Displacement Evolution of a Large Landslide in a Highly Fissured Clay
2019
The paper presents an analysis and modelling of the reactivation mechanism of a large landslide caused by rainfall, located in Cerda (Sicily, Italy). The study is based on data collected by means of a field investigation, carried out in order to assess the geotechnical properties of the involved material, and a three-year monitoring programme implemented to measure rain and pore water pressures as well as deep and superficial displacements. Three distinct landslides, evolving at variable rates in different directions, were recognized within the overall landslide area. The data clearly show the mechanical role of pore water pressures in the stability of the slope and point out the dependence…
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…

Long-term results after operative treatment of femoral neck fractures with ceramic head prostheses.
2001
ABSTRACT From 1 985-1 990, a total of 277 elderly patients underwent hemiarthroplasty using a ceramic head prosthesis. Average patient age was 81.7 years. Of these, 77 patients were available for follow-up examination in 1993. A standardized score was calculated assessing activity, gait, and hip pain; the average score was 58 out of 78 possible points. Three patients had hip pain, and in 4 patients, radiographic examination revealed protrusio acetabuli. Two of 4 patients underwent revision surgery for replacement of the cup, leaving the stem in situ. Because of the small number of prosthetic-related complications, hemiarthroplasty using a ceramic head prosthesis is the recommended surgical …
