Training of laparoscopic surgery in Virtual Reality (VR) environment has been proved as an effective step before clinical practice. Tracking the position of instruments in realtime is an essential part of developing a VR trainer. In this study, we used Microsoft Kinect and color markers instead of using similar traditional means such as mechanical sensors. The orientation and position of instruments were determined and compared with the results obtained using the SinaSim commercial laparoscopic surgery trainer, which measures these values using encoders...

Emergency Cricothyroidotomy (CCT) is a surgical procedure performed to secure a patient's airway. This high-stakes, but seldom-performed procedure is an ideal candidate for a virtual reality simulator to enhance physician training. For the first time, this study characterizes the force/torque characteristics of the cricothyroidotomy procedure, to guide development of a virtual reality CCT simulator for use in medical training. We analyze the upper force and torque thresholds experienced at the human-scalpel interface...

BACKGROUND: Virtual reality (VR) has recently been explored as a tool for neurorehabilitation to enable individuals with Parkinson's disease (PD) to practice challenging skills in a safe environment. Current technological advances have enabled the use of affordable, fully immersive head-mounted displays (HMDs) for potential therapeutic applications. However, while previous studies have used HMDs in individuals with PD, these were only used for short bouts of walking. Clinical applications of VR for gait training would likely involve an extended exposure to the virtual environment, which has the potential to cause individuals with PD to experience simulator-related adverse effects due to their age or pathology...

Stroke patients usually suffer from asymmetric posture due to hemi-paresis that can result in reduced postural controllability leading to a balance deficit. This deficit increases the risk of falls, which often makes them dependent on caregivers for community ambulation, thus deteriorating their quality of life. Conventional balance training involves rehabilitation exercises performed under physiotherapist's supervision where the scarcity of trained professionals as well as the cost of clinic-based rehabilitation programs can deter stroke survivors from undergoing regular balance training...

BACKGROUND: Linear endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) represents a pivotal innovation in interventional pulmonology; determining the best approach to guarantee systematic and efficient training is expected to become a main issue in the forthcoming years. Virtual reality simulators have been proposed as potential EBUS-TBNA training instruments, to avoid unskilled beginners practicing directly in real-life settings. A validated and perfected simulation program could be used before allowing beginners to practice on patients...

BACKGROUND/OBJECTIVES: Universal screening for elder abuse and neglect is a current controversy in geriatrics, fueled by the lack of evidence on valid and reliable instruments. Since each U.S. State and many other countries have their own legal definitions of what constitutes elder abuse and neglect, this further complicates instrument development and clinical assessment. The purpose of this paper is to present data on the sensitivity and specificity of the QualCare Scale, an instrument with utility in detecting clinically significant elder abuse and neglect among older adults receiving care at home...

BACKGROUND: Simulation in medicine is an indispensable tool to improve doctors' responses to different situations, enhancing their performance. However, simulation in ophthalmology is a very recent trend, mainly because of the high complexity of developing newer teaching tools, with the need for highly realistic models, mostly in surgical ophthalmic simulation. DISCUSSION: The whole development of simulation in ophthalmology, from the very first attempts that used basic models, to the newer virtual reality models, allows for a comprehensive, faster, and more efficient development of skills necessary in basic and advance procedures in ophthalmology, creating a better learning environment, improving costs, and developing a very promising panorama, in which simulation can be incorporated in teaching programs all around the globe...

BACKGROUND: Children with attention-deficit/hyperactivity disorder (ADHD) suffer from attention deficits, motor hyperactivity, and impulsive behaviour. These impairments are experienced at home, at school, and with friends. Functional imaging studies show that ADHD behaviour and impairments in executive functions (EFs) are mirrored by aberrant neurophysiological functioning. Moreover, several studies show that ADHD behaviour, impairments in EFs, and a lack of self-control contribute to poor school performance...

BACKGROUND: Acquired brain injury (ABI) may result in lifelong impairment of physical, cognitive, and psychosocial functions. Several rehabilitative treatments are often needed to support walking recovery, thus participants' engagement becomes a crucial aspect, especially when patients are children. In the last few years, traditional physiotherapy (PT) has been flanked by innovative technologies for rehabilitation in the fields of robotics and Virtual Reality (VR). Preliminary results have shown interesting perspectives in the use of a VR system, the GRAIL (Gait Real-time Analysis Interactive Lab), in improving walking abilities in a small group of children with ABI, although further insights are needed about its use as rehabilitative tool in the pediatric population...

V Mitrousia, O Giotakos
During the last decade a number of studies have been conducted in order to examine if virtual reality exposure therapy can be an alternative form of therapy for the treatment of mental disorders and particularly for the treatment of anxiety disorders. Imaginal exposure therapy, which is one of the components of Cognitive Behavioral Therapy, cannot be easily applied to all patients and in cases like those virtual reality can be used as an alternative or a supportive psychotherapeutic technique. Most studies using virtual reality have focused on anxiety disorders, mainly in specific phobias, but some extend to other disorders such as eating disorders, drug dependence, pain control and palliative care and rehabilitation...

Kwang-Ryeol Lee, Won-Du Chang, Sungkean Kim, Chang-Hwan Im
Eye movements can be used as alternative inputs for human-computer interface (HCI) systems such as virtual or augmented reality systems as well as new communication ways for patients with locked-in syndrome. In this study, we developed a real-time electrooculogram (EOG)-based eye-writing recognition system, with which users can write predefined symbolic patterns with their volitional eye movements. For the 'eye-writing' recognition, the proposed system first reconstructs the eye-written traces from EOG waveforms in real-time; then, the system recognizes the intended symbolic inputs with a reliable recognition rate by matching the input traces with the trained eye-written traces of diverse input patterns...

Many types of virtual reality (VR) systems allow users to use natural, physical head movements to view a 3D environment. In some situations, such as when using systems that lack a fully surrounding display or when opting for convenient low-effort interaction, view control can be enabled through a combination of physical and virtual turns to view the environment, but the reduced realism could potentially interfere with the ability to maintain spatial orientation. One solution to this problem is to amplify head rotations such that smaller physical turns are mapped to larger virtual turns, allowing trainees to view the entire surrounding environment with small head movements...
