AbstractTo study the usefulness of virtual reality (VR)-based training for diagnosing strabismus. Fourteen residents in ophthalmology performed at least 30 VR training sessions to diagnose esotropia and exotropia. Examinations of real patients with esotropia or exotropia before and after the VR training were video-recorded and presented to a strabismus expert to assess accuracy and performance scores for measuring the deviation angle and diagnosing strabismus with anonymization. A feedback survey regarding the usefulness and ease of use of the VR application was conducted for participants. The mean age of the 14 ophthalmology residents (10 men and 4 women), was 29.7 years. Before VR training, participants showed a mean accuracy score of 14.50 ± 5.45 and a performance score of 9.64 ± 4.67 for measuring the deviation angle and diagnosing strabismus in real patients with strabismus. After VR training, they showed a significantly improved accuracy score of 22.14 ± 4.37 (p = 0.012) and a performance score of 15.50 ± 1.99 (p = 0.011). According to the survey, most participants agreed on the usefulness of VR applications. This study suggests that VR-based training improved ophthalmology residents’ clinical diagnostic skills for strabismus in a short period.

Objectives: Cardiopulmonary resuscitation (CPR) is lifesaving. Yet, cardiac arrest survival remains low despite CPR intervention. Education has been highlighted as a strategy to overcome this issue. Virtual Reality technology has been gaining momentum in the field of clinical education. Published studies report benefits of virtual reality for CPR education; yet, perceptions of CPR instructors towards virtual reality remain unexplored. CPR instructors are key stakeholders in CPR education and their perceptions are valuable for the design and adoption of virtual reality-enhanced learning. The purpose of this study is therefore to understand the perceptions of CPR instructors towards using virtual reality for health professionals’ CPR education. The aim was addressed via three research questions: (1) What are the perceptions of CPR instructors towards current health professionals’ CPR education? (2) What are the perceptions of CPR instructors towards features of virtual reality ideal for health professionals’ CPR education? (3) What are the perceptions of CPR instructors towards the potential role of virtual reality in health professionals’ CPR education? Methods: A total of 30 CPR instructors were surveyed on their views towards current health professionals’ CPR education and the use of virtual reality for health professionals’ CPR education, before and after interacting with a CPR virtual reality simulation. Responses were analysed using interpretative thematic analysis. Results: CPR instructors perceived current health professionals’ CPR education as limited due to unideal test preparation (resources, practice, motivation, and frame of mind) and performance. They perceived fidelity, engagement, resource conservation, and memory enhancement as features of virtual reality ideal for health professionals’ CPR education. Virtual reality was viewed by CPR instructors as having potential as a blended learning tool, targeting both ‘novice’ and ‘experienced’ health professionals. Conclusion: The study highlighted the gaps in current health professionals’ CPR education that can be addressed using virtual-reality-enabled learning. Future research could investigate virtual reality simulations with features desirable for CPR education of target populations.

Background: Despite an alarming rise in the global prevalence of dementia, the available modalities for improving cognition and mental wellbeing of dementia patients remain limited. Environmental enrichment is an experimental paradigm that has shown promising anti-depressive and memory-enhancing effects in pre-clinical studies. However, its clinical utility has remained limited due to the lack of effective implementation strategies. Objective: The primary objective of this study was to evaluate the usability (tolerability and interactivity) of a long-term virtual reality (VR)- based environmental enrichment training program in older adults with mild cognitive impairment (MCI) and mild dementia. A secondary objective was to assess the effect of VR-based environmental enrichment on stabilization of cognitive functioning and improvement of mental wellbeing in older adults with MCI and mild dementia. Methods: A total of seven participants (four patients with MCI and three with mild dementia) received biweekly VR-based environmental enrichment over a course of 6 months. The tolerability and interactivity of the participants in the VR training was serially assessed via virtual reality sickness questionnaire (VRSQ) and recording of input-error ratio. Cognitive functioning was assessed through Montreal cognitive assessment (MoCA) before and after the study. Mental wellbeing was assessed through Warwick-Edinburgh Mental Well Being Scale (WEMWBS). Results: VR-based environmental enrichment was well-tolerated by the patients with significant decrease in VRSQ scores (p < 0.01) and input-error ratio (p < 0.001) overtime. VR training was also effective in stabilization of MoCA scores over the course of therapy (non-significant difference in the MoCA scores before and after the therapy) and was associated with a trend (p < 0.1) towards improvement in WEMWBS scores between the first and the last assessments. Qualitative observations by the care-givers further corroborated a noticeable improvement in mental wellbeing of patients. Conclusions: This pilot study shows that VR can be a feasible, tolerable, and potentially effective tool in long-term support of older adults with MCI and mild dementia.

Virtual reality (VR) offers the potential to train medical students on high-risk situations. The current study investigated VR training of medical students to diagnose and treat a patient avatar experiencing a serious head injury. The user interface was investigated, including use of tools, comfort and VR locomotion, and found to be sufficiently high to warrant training within a medical curriculum. In addition, actual learning as a function of VR training was assessed by comparing medical students' knowledge structures to an expert knowledge structure before and after training. Students' knowledge structures became more similar to an expert's knowledge structure indicating that their conceptual understanding of core head-injury concepts increased as a result of VR training. The study was carried out under the auspices of Project TOUCH (Telehealth Outreach for Unified Community Health), a multi-year collaboration between The University of Hawaii (UH) and The University of New Mexico (UNM).

BACKGROUND Cardiac arrest after cardiac surgery commonly has a reversible cause, where often emergency re-sternotomy is required for treatment, as recommended by international guidelines. We have developed a virtual reality (VR) simulation for training of CPR and emergency re-sternotomy procedures after cardiac surgery, the CardioPulmonary resuscitation VR-simulator (CPVR-sim). In this prospective study, we researched face validity and content validity of this CPVR-sim. OBJECTIVE We designed a prospective study to assess the feasibility and to establish the face and content validity of CPVR-sim in a group of novices and experts in performing CPR and emergency re-sternotomies in patients after cardiac surgery. METHODS Thirty clinicians (staff cardiothoracic surgeons, physicians, surgical residents, and nurse practitioners) participated as either an expert or novice, based on experience with emergency re-sternotomy. All performed the simulation and completed the questionnaire rating the simulator’s usefulness, satisfaction, ease of use, effectiveness, and immersiveness to assess face validity and content validity. RESULTS Responses towards face validity and content validity were predominantly positive in both groups. Most participants felt actively involved (97%), in charge of the situation (73%), it was easy to learn how to interact with the software (80%), and the software responded well (70%). Almost all expert-participants preferred VR training as a substitute to conventional (100%) and digital (60% agreed and 40% was neutral) training. Moreover, 86% of the expert-participants would recommend VR training to other colleagues, and 93% found that CPVR-sim is a useful method to train infrequent CPR-cases after cardiac surgery. CONCLUSIONS We developed a proof-of-concept of a VR simulation for CPR training after cardiac surgery, which participants found was immersive and useful. By proving the face validity and content validity of CPVR-sim, we present a first step towards a cardiothoracic surgery VR training platform.

Oxidative Stress Indicators

This study was conducted to explore the effect of hyperbaric oxygen (HBO) therapy combined with virtual reality (VR) training on oxidative stress indicators (OSIs) and inflammatory factors (IFs) in swimming athletes with depression. 88 swimming athletes suffering from depression were grouped into a control group (group C) and a research group (group R). The patients in group C were given HBO therapy, and the group R was given HBO therapy combined with VR training. The Physical Health Questionnaire (PHQ-9) and the Symptom Checklist (SCL-90) were adopted to assess the depression status of patients. The differences between the two groups of serum OSIs and IFs before and after the intervention were compared and analyzed. The results disclosed that the PHQ-9 score and SCL-90 score in group R were not different from those in group C before the intervention, but those in group R were greatly decreased in contrast to group C after the intervention ( P < 0.05 ). Before the intervention, there was no obvious difference in the OSIs and the IFs between the two groups. The levels of interleukin-1β (IL-1β), interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor-α (TNF-α) in the two groups were decreased greatly after intervention, and those in the group R were much lower than those in group C ( P < 0.05 ). Compared with the preintervention, the levels of malondialdehyde (MDA) in both groups were reduced observably, and the levels of superoxide dismutase (SOD), nitric oxide (NO), and glutathione peroxidase (GSH-Px) were dramatically increased. The MDA in group R was much lower, while the SOD, NO, and GSH-Px were much higher in contrast to group C ( P < 0.05 ). It indicated that HBO combined with VR training had a good clinical effect for swimming athletes suffering from depression, and it could reduce the oxidative stress and inflammation, thereby helping patients recover quickly.

OBJECTIVE: We aimed to determine whether the posture control training in the sitting posture using virtual reality (VR) training program affects sitting balance and trunk stability in children with spastic cerebral palsy (CP). METHODS: The experiment was conducted for 4 weeks by randomly allocating 20 children with CP. The experimental group (n = 10) performed balance training in the sitting position using a VR training program, and the control group (n = 10) performed arm reach training in the sitting position. To evaluate static and dynamic sitting balance and trunk stability, the Wii Balance Board and Balancia software, the modified functional reach test, and the Korean version of the Trunk Control Measurement Scale were used. RESULTS: There were significant differences between the two groups in the changes in speed and postural swing distance before and after training (p < 0.05). The mFRT measurement showed significant differences in all directions before and after training between the two groups (p < 0.05). However, there was no significant difference between the two groups in the K-TCMS score. CONCLUSIONS: Posture control training in the sitting position using a VR training program was found to be more effective in improving the sitting balance and trunk stability of children with CP.

Abstract This study was conducted to evaluate whether cooled floor pads combined with chilled drinking water could alleviate negative impacts of heat stress on lactating sows. Thirty sows (Landrace × Yorkshire, Parity = 1 to 6) were housed in individual farrowing stalls in two rooms with temperatures being controlled at 29.4°C (0700–1900 hours) and 23.9°C (1900–0700 hours). Sows in one room (Cool), but not in the other room (Control) were provided cooled floor pads (21–22°C) and chilled drinking water (13–15°C). Behavior of sows (15 sows/treatment) was video recorded during farrowing, and days 1, 3, 7, 14, and 21 after farrowing. Videos were viewed continuously to register the birth time of each piglet, from which total farrowing duration and birth intervals were calculated. The number of drinking bouts and the duration of each drinking bout were registered for each sow through viewing videos continuously for 2 h (1530–1730 hours) each video-recording day. Postures (lying laterally, lying ventrally, sitting, and standing) were recorded by scanning video recordings at 5-min intervals for 24 h each video-recording day, and time budget for each posture was calculated. Rectal temperature and respiration rate were measured for all sows the day before and after farrowing, and then once weekly. Sow and litter performance was recorded. Data were analyzed using the Glimmix procedure of SAS. The cooling treatment did not affect sow behavior or litter performance. Sows in the Cool room had lower rectal temperature (P = 0.03) and lower respiration rate (P &lt; 0.001), consumed more feed (P = 0.03), tended to have reduced weight loss (P = 0.07), and backfat loss (P = 0.07) during lactation than sows in the Control room. As lactation progressed, sows increased drinking frequency (P &lt; 0.001) and time spent lying ventrally (P &lt; 0.0001), standing (P &lt; 0.001), and sitting (P &lt; 0.0001), and decreased time spent lying laterally (P &lt; 0.0001) in both Cool and Control rooms. While cooled floor pads combined with chilled drinking water did not affect sow behavior, they did alleviate heat stress partially, as indicated by decreased rectal temperature, respiration rate, weight, and backfat loss, and increased feed intake in lactating sows.

Check-in/Check-Out (CICO) has a long line of research evidence demonstrating its effectiveness in increasing prosocial behavior. The current paper demonstrated an electronic application of CICO utilizing Google Sheets® with teacher feedback. Google Sheets® offers an inexpensive, collaborative, and remote method for tracking behaviors. In the first study, 2,322 teacher ratings (from 38 teachers) were compared between traditional paper CICO forms or electronic Google Sheets®. Results found that teacher ratings were significantly more complete with the use of the electronic forms. In the second study, an electronic CICO form was used for progress monitoring and performance feedback with a middle school student. Through the form we were able to successfully track our participant’s behavior change in response to CICO with the combination of feedback and a differential reinforcement intervention. Social validity showed that overall teacher ratings were high with respect to ease of use, usefulness, cost-effectiveness, and convenience of the electronic Google Sheets®.
