Conventional education results in unsatisfactory morphological understanding of acetabular fractures due to lack of three-dimensional (3D) details and tactile feedback of real fractures. Virtual reality (VR) and 3D printing (3DP) techniques are widely applied in teaching. The purpose of this study was to identify the effect of physical model (PM), VR and 3DP models in education of morphological understanding of acetabular fractures. 141 students were invited to participate in this study. Participants were equally and randomly assigned to the PM, VR and 3DP learning groups...

Visualization of sensor networks, data, and metadata is becoming one of the most pivotal aspects of the structural health monitoring (SHM) process. Without the ability to communicate efficiently and effectively between disparate groups working on a project, an SHM system can be underused, misunderstood, or even abandoned. For this reason, this work seeks to evaluate visualization techniques in the field, identify flaws in current practices, and devise a new method for visualizing and accessing SHM data and metadata in 3D...

Health-related emerging technologies are growing fast. The use of virtual reality in diabetes outpatient care still remains unprecedented, notably in Switzerland. Thus, the Programme cantonal Diabète led a pilot study to assess the feasibility of an immersive application in such an outpatient setting. Results emphasize that this device is practicable and useful in diabetes care. Patients and their relatives overall appreciate the game, each of them for specific reasons: playful quality, opportunity to « learn differently » or to exchange about the subjective experience...

The last 25 years have brought about revolutionary changes for medicine and in particular for urology: internet was only in its infancy, medical records were written on paper, searches for medical information were done in the hospital library, medical articles were photocopied and our relationship with patients only existed face to face. Social networks had not yet appeared and even Google did not exist. Just imagine what might happen during the next 25 years, we're going to see even more radical changes. The urologist of the future is going to see the arrival of artificial intelligence, collaborative medicine, telemedicine, machine learning, the Internet of Things and personalized robotics; in the meantime, social media will continue to transform the interaction between physician and patient...

Andrew J J Smith, Edward D Lemaire
This study assessed the relationship between walking speed and common temporal-spatial stride-parameters to determine if a change in gait strategy occurs at extremely slow walking speeds. Stride-parameter models that represent slow walking can act as a reference for lower extremity exoskeleton and powered orthosis controls since these devices typically operate at walking speeds less than 0.4 m/s. Full-body motion capture data were collected from 30 health adults while walking on a self-paced treadmill, within a CAREN-Extended virtual reality environment...

We demonstrate a novel phase-only modulation mode based on the pre-transitional effect of the antiferroelectric liquid crystal. 2π phase modulation without changing the polarization state of the incident light is achieved with a low field (1.8 V/μm). This phase modulation mode also shows an ultrafast response time (less than 300 μs) and a uniform optical texture with an easy fabrication process. This phase modulator can be applied to laser beam steering, virtual reality, and holograms, etc., in the future...

Visually induced motion sickness (VIMS) is a common discomfort response associated with vection-provoking stimuli. It is suggested that VIMS susceptibility depends on the ability to regulate visual performance during vection. To test this, in total 29 participants, with VIMS susceptibility assessed by Motion Sickness Susceptibility Questionnaire, were recruited in three successive experiments to perform sustained attention to response tests (SARTs) while watching dot pattern stimuli known to provoke roll-vection...

Embodiment and agency are key aspects of how we perceive ourselves that have typically been associated with independent mechanisms. Recent work, however, has suggested that these mechanisms are related. The sense of agency arises from recognising a causal influence on the external world. This influence is typically realised through bodily movements and thus the perception of the bodily self could also be crucial for agency. We investigated whether a key index of agency - intentional binding - was modulated by body-specific information...

INTRODUCTION: Preoperative anxiety may lead to medical and surgical complications, behavioral problems and emotional distress. The most common means of prevention are based on using medication and, more recently, hypnosis. The aim of our study was to determine whether a virtual reality (VR) program presenting natural scenes could be part of a new therapy to reduce patients' preoperative anxiety. MATERIALS AND METHODS: Our prospective pilot study consisted of a single-blind trial in skin cancer surgery at the Henri Mondor Teaching Hospital in France...

Over recent decades many researchers and clinicians have started to use Virtual Reality (VR) as a new technology for implementing innovative rehabilitation treatments in cognitive and motor domains. However, the expression "VR" has often also been improperly used to refer to video games. Further, VR efficacy, often confused with that of video-game exercises, is still debated. Areas covered: In this review, we provide the scientific rationale for the advantages of using VR systems in rehabilitation and investigate whether the VR could really be a promising technique for the future of rehabilitation of patients, or if it is just an entertainment for scientists...

BACKGROUND: The demonstration of competency in endoscopy is required prior to obtaining American Board of Surgery Certification. To demonstrate competency, the resident must pass a national high-stakes cognitive test and a technical skills exam on a virtual reality simulator. The purpose of this preliminary study was to design a proficiency-based endoscopy simulation curriculum to meet this competency requirement. METHODS: This is a mixed methods prospective cohort study at a single academic medical institution...

Burn care often involves procedures that result in significant pain experiences for patients which, in turn, can lead to poorer physical and psychological health outcomes. Distraction and virtual reality (VR) are an effective adjunct to pharmacological interventions in reducing pain. Much of the research that has demonstrated efficacy for VR in burn care has involved expensive and extensive technology. Thus, identifying cost-effective, feasible, acceptable, and effective approaches to apply distraction within routine burn care is important...

BACKGROUND: Recovery of voluntary movement is a main rehabilitation goal. Efforts to identify effective upper limb (UL) interventions after stroke have been unsatisfactory. This study includes personalized impairment-based UL reaching training in virtual reality (VR) combined with non-invasive brain stimulation to enhance motor learning. The approach is guided by limiting reaching training to the angular zone in which active control is preserved ("active control zone") after identification of a "spasticity zone"...

Despite growing interest in the use of bystander education programs to address the problems of sexual and relationship violence on college campuses, little knowledge exists on adverse consequences experienced by students intervening as a bystander. The current study examined the prevalence and correlates of adverse consequences of bystander intervention in two samples of first-year college students. In Study 1, 281 students completed a measure of negative consequences experienced when acting as a bystander to help someone at risk of sexual assault, relationship abuse, or stalking...

BACKGROUND: Psychotic disorders are characterized by a deranged immune system, including altered number and function of Natural Killer (NK) and T cells. Psychotic disorders arise from an interaction between genetic vulnerability and exposure to environmental risk factors. Exposure to social adversity during early life is particularly relevant to psychosis risk and is thought to increase reactivity to subsequent minor daily social stressors. Virtual reality allows controlled experimental exposure to virtual social stressors...

Post-traumatic stress disorder (PTSD) is characterized by impairments in mnestic functions, especially in the domain of episodic memory. These alterations might affect different aspects of episodic memory functioning. Here we tested PTSD patients and healthy controls (matched for age, sex and education) in a newly developed virtual reality episodic memory test (VR-EMT), a test for mental time travel, episodic future thinking, and prospective memory (M3xT). In a cross-validation experiment, their performance was further evaluated in the Rivermead Behavioral Memory Test (RBMT)...
