OJECTIVE: Ultrasound guided central venous catheterization (CVC) is a common surgical procedure with complication rates ranging from 5 to 21 percent. Training is typically performed using manikins that do not simulate anatomical variations such as obesity and abnormal vessel positioning. The goal of this study was to develop and validate the effectiveness of a new virtual reality and force haptic based simulation platform for CVC of the right internal jugular vein. DESIGN: A CVC simulation platform was developed using a haptic robotic arm, 3D position tracker, and computer visualization...

Anna M Berger, Eddy J Davelaar
Two competing views about alpha oscillations suggest that cortical alpha reflect either cortical inactivity or cortical processing efficiency. We investigate the role of alpha oscillations in attentional control, as measured with a Stroop task. We use neurofeedback to train 22 participants to increase their level of alpha amplitude. Based on the conflict/control loop theory, we selected to train prefrontal alpha and focus on the Gratton effect as an index of deployment of attentional control. We expected an increase or a decrease in the Gratton effect with increase in neural learning depending on whether frontal alpha oscillations reflect cortical idling or enhanced processing efficiency, respectively...

BACKGROUND: The aim was to determine whether a simulation-based care pathway approach (CPA) curriculum could improve compliance for enhanced recovery programs (ERP), and residents' participation in laparoscopic colorectal surgery (LCS). Indeed, trainee surgeons have limited access to LCS as primary operator, and ERP have improved patients' outcomes in colorectal surgery (CS). METHODS: All residents of our department were trained in a simulation-based CPA: perioperative training consisted in virtual patients built according to guidelines in both ERP and CS, whilst intraoperative training involved a virtual reality simulator curriculum...

One of the biggest problems of upper limb transplantation is lack of certainty as to whether a patient will be able to control voluntary movements of transplanted hands. Based on findings of the recent research on brain cortex plasticity, a premise can be drawn that mental training supported with visual and sensory feedback can cause structural and functional reorganization of the sensorimotor cortex, which leads to recovery of function associated with the control of movements performed by the upper limbs. In this study, authors - based on the above observations - propose the computer-aided training (CAT) system, which generating visual and sensory stimuli, should enhance the effectiveness of mental training applied to humans before upper limb transplantation...

Simulation and planning of surgery using a virtual reality model is becoming common with advances in computer technology. In this study, we conducted a literature search to find trends in virtual simulation of surgery for brain tumors. A MEDLINE search for "neurosurgery AND (simulation OR virtual reality)" retrieved a total of 1,298 articles published in the past 10 years. After eliminating studies designed solely for education and training purposes, 28 articles about the clinical application remained. The finding that the vast majority of the articles were about education and training rather than clinical applications suggests that several issues need be addressed for clinical application of surgical simulation...

BACKGROUND: Hysteroscopy is performed often and in many indications but is challenging to learn. Hands-on training in live patients faces ethical, legal, and economic obstacles. Virtual reality simulation may hold promise as a hysteroscopy training tool. No validated curriculum specific in hysteroscopy exists. The aim of this study was to develop a hysteroscopy curriculum, using the Delphi method to identify skill requirements. METHODS: Based on a literature review using the key words "curriculum," "simulation," and "hysteroscopy," we identified five technical and non-technical areas in which skills were required...

BACKGROUND: Exposure therapy is an established learning-based intervention for the treatment of anxiety disorders with an average response rate of nearly 50%, leaving room for improvement. Emerging strategies to enhance exposure therapy in humans and fear extinction retention in animal models are primarily pharmacological. These approaches are limited as many patients report preferring non-pharmacological approaches in therapy. With general cognitive enhancement effects, exercise has emerged as a plausible non-pharmacological augmentation strategy...

BACKGROUND: Practice on virtual reality simulators (VRSs) has been shown to improve surgical performance. However, VRSs are expensive and usually housed in surgical skills centers that may be inaccessible at times convenient for surgical trainees to practice. Conversely, box trainers (BT) are inexpensive and can be used anywhere at anytime. This study assesses "take-home" BTs as an alternative to VRS. METHODS: After baseline assessments (two simulated laparoscopic cholecystectomies, one on a VRS and one on a BT), 25 surgical trainees were randomized to two groups...

BACKGROUND: Many studies have demonstrated the usefulness of repetitive task practice by using robotic-assisted gait training (RAGT) devices, including Lokomat, for the treatment of lower limb paresis. Virtual reality (VR) has proved to be a valuable tool to improve neurorehabilitation training. The aim of our pilot randomized clinical trial was to understand the neurophysiological basis of motor function recovery induced by the association between RAGT (by using Lokomat device) and VR (an animated avatar in a 2D VR) by studying electroencephalographic (EEG) oscillations...

Recently, virtual reality (VR) and augmented reality (AR) have received increasing attention, with the development of VR/AR devices such as head-mounted displays, haptic devices, and AR glasses. Medicine is considered to be one of the most effective applications of VR/AR. In this article, we describe a systematic literature review conducted to investigate the state-of-the-art VR/AR technology relevant to plastic surgery. The 35 studies that were ultimately selected were categorized into 3 representative topics: VR/AR-based preoperative planning, navigation, and training...

BACKGROUND: Historically, operating room (OR) has always been considered as a stand-alone trusted platform for surgical education and training. However, concerns about financial constraints, quality control, and patient safety have urged the surgical educators to develop more cost-effective, surgical educational platforms that can be employed outside the OR. Furthermore, trained surgeons need to regularly update their surgical skills to keep abreast with the emerging surgical technologies...

OBJECTIVE: Nontechnical skills are an essential component of surgical education and a major competency assessed by the ACGME milestones project. However, the optimal way to integrate nontechnical skills training into existing curricula and then objectively evaluate the outcome is still unknown. The aim of this study was to determine the effect laparoscopic team-based task training would have on the nontechnical skills needed for laparoscopic surgery. DESIGN: 9 PGY-1 residents underwent an established training curriculum for teaching the knowledge and technical skills involved in laparoscopic cholecystectomy...

A cephalosomatic anastomosis (CSA; also called HEAVEN: head anastomosis venture) has been proposed as an option for patients with neurological impairments, such as spinal cord injury (SCI), and terminal medical illnesses, for which medicine is currently powerless. Protocols to prepare a patient for life after CSA do not currently exist. However, methods used in conventional neurorehabilitation can be used as a reference for developing preparatory training. Studies on virtual reality (VR) technologies have documented VR's ability to enhance rehabilitation and improve the quality of recovery in patients with neurological disabilities...
