What is the accuracy of the surgical guide in the planning of orthognathic surgeries? A systematic review.
2021
BACKGROUND To investigate the true accuracy of the surgical guide in the planning of orthognathic surgeries, which are performed worldwide. MATERIAL AND METHODS A systematic search was conducted in the PubMed database, Web of science, Scopus and Embase, covering August 2020 to January 2021. Studies that included patients with dentofacial deformity including anteroposterior, vertical and asymmetry problems who were undergoing an orthognathic surgery procedure were included; QUADAS-2 was used to determine the risk of bias by analyzing the quality of the studies. A PRISMA (flowchart) was created to show the study selection, keywords, nomination processes, and inclusion and exclusion criteria. …
Stereoscopic Viewing Enhances Visually Induced Motion Sickness but Sound Does Not
2012
Optic flow in visual displays or virtual environments often induces motion sickness (MS). We conducted two studies to analyze the effects of stereopsis, background sound, and realism (video vs. simulation) on the severity of MS and related feelings of immersion and vection. In Experiment 1, 79 participants watched either a 15-min-long video clip taken during a real roller coaster ride, or a precise simulation of the same ride. Additionally, half of the participants watched the movie in 2D, and the other half in 3D. MS was measured using the Simulator Sickness Questionnaire (SSQ) and the Fast Motion Sickness Scale (FMS). Results showed a significant interaction for both variables, indicatin…
Innovative Educational Pathways in Spine Surgery: Advanced Virtual Reality–Based Training
2020
Background Over the past few years, a reorganization of the educational pathways has been promoted with the purpose of optimizing the acquisition of competences and their assessment, so as to reduce the risks to both health care professionals and end users. Virtual reality (VR) has been repeatedly tested, initially as a positive reinforcement for more traditional educational pathways and, more recently, as their potential substitute. The aim of this study was to demonstrate the potentiality of VR simulation training in spine surgery. Methods The VR simulator reproduced the lateral lumbar access to the spine. The simulation included a tutorial, the preoperative settings, and the surgical ses…
A multiparametric magnetic resonance imaging-based virtual reality surgical navigation tool for robotic-assisted radical prostatectomy
2019
Objective Increased computational power and improved visualization hardware have generated more opportunities for virtual reality (VR) applications in healthcare. In this study, we test the feasibility of a VR-assisted surgical navigation system for robotic-assisted radical prostatectomy. Material and methods The prostate, all magnetic resonance imaging (MRI) visible tumors, and important anatomic structures like the neurovascular bundles, seminal vesicles, bladder, and rectum were contoured on a multiparametric MRI using an in-house segmentation software. Three-dimensional (3-D) VR models were rendered and evaluated in a side room of the operating room. While interacting with the VR platfo…

Commentary: Preliminary Evidence for Training-Induced Changes of Morphology and Phantom Limb Pain
2019
The aim of this study was to investigate whether a special prosthetic training in phantom limb pain patients aimed at increasing the functional use of the prosthesis leads to neural morphological plasticity of brain structures and a reduction in phantom limb pain. For chronic pain disorders, it was shown that morphological alterations due to pain might become at least partially reversed by pain therapies. Phantom limb pain is a chronic pain disorder that is frequently followed by neural plasticity of anatomical brain structures. In our study, 10 patients with amputation of the upper limb participated in a two-week training with a myoelectric prosthesis with somatosensory feedback. Grip stre…
Cómo crear una actividad H5P de juego de memoria en el Aula Virtual
2022
En este videotutorial se muestra cómo crear una actividad H5P de juego de memoria (memory game) en el Aula Virtual (Moodle 3.11). Este trabajo forma parte del Proyecto de Innovación Docente Multimedia learning objects in Moodle: Sustainable Development Goals (Ref: UV-SFPIE_PID-1640789) financiado por el Vicerrectorado de Ocupación y Programas Formativos de la Universitat de València en el curso académico 2021/2022.
Designing for virtual mobility: Potentials and caveats
2019
This paper reflects on the joint pilot development and implementation of an international master level online course in Educational Design by three universities from different European countries. The pilot targeted curriculum internationalization and provision of international learning experiences to students with less mobility opportunities through online learning and use of technology. The key focus was on connecting students from different countries by collaborative learning and working on an authentic task in the professional domain of their study - educational media design - via a joint platform and digital media. In small international groups, students collaboratively developed mobile…
“Ihmisiltä poissa” – away from people : language learning spaces in Finnish as a foreign language students’ chat during the covid-19 pandemic
2020
Smart phones enable learners to practice language use in different spaces and environments beyond the classroom. Finnish language students in two North American universities participated in a collaborative chat project as part of their second-year language course. In this article we analyze how students' chat entries reflected their learning in different domestic spaces during the global covid-19 pandemic in spring 2020. nonPeerReviewed
Il padiglione siciliano all’esposizione di Roma del 1911: dai disegni di Ernesto Basile alla ricostruzione virtuale
2022
A partire dalla rilettura di disegni originali di progetto, rare foto e riproduzioni grafiche d’epoca, il contributo indaga il Padiglione Siciliano, progettato da Ernesto Basile per l’Esposizione di Roma del 1911, attraverso strumenti e metodi della rappresentazione, per giungere alla realizzazione di ricostruzioni tridimensionali digitali che descrivono l’architettura perduta in maniera filologica e quanto più fedele. La prima fase di studio è stata dedicata all’analisi critica delle testimonianze iconografiche rintracciate. La seconda fase ha riguardato il confronto geometrico-dimensionale con le architetture del XII secolo individuate quale riferimento per il progetto di Basile. La terza…
