Systematic review of randomized controlled trials on the effectiveness of virtual reality training for laparoscopic surgery.
TLDR
The aim of this review was to determine whether virtual reality (VR) training can supplement and/or replace conventional laparoscopic training in surgical trainees with limited or no Laparoscopic experience.Abstract:
Background: Surgical training has traditionally been one of apprenticeship. The aim of this review was to determine whether virtual reality (VR) training can supplement and/or replace conventional laparoscopic training in surgical trainees with limited or no laparoscopic experience. Methods: Randomized clinical trials addressing this issue were identified from The Cochrane Library trials register, Medline, Embase, Science Citation Index Expanded, grey literature and reference lists. Standardized mean difference was calculated with 95 per cent confidence intervals based on available case analysis. Results: Twenty-three trials (mostly with a high risk of bias) involving 622 participants were included in this review. In trainees without surgical experience, VR training decreased the time taken to complete a task, increased accuracy and decreased errors compared with no training. In the same participants, VR training was more accurate than video trainer (VT) training. In participants with limited laparoscopic experience, VR training resulted in a greater reduction in operating time, error and unnecessary movements than standard laparoscopic training. In these participants, the composite performance score was better in the VR group than the VT group. Conclusion: VR training can supplement standard laparoscopic surgical training. It is at least as effective as video training in supplementing standard laparoscopic training.read more

Virtual reality in orthopaedics: is it a reality?
TL;DR: In this article, virtual reality (VR) simulation has been a requirement for airline and military pilots for decades and is only now being integrated into surgical training programs, thus far, orthopaedic training programs have been slow to adopt VR training.

Adaptive virtual reality-based training: a systematic literature review and framework
TL;DR: Adaptive VR-based training can be improved by using real-time kinematic/kinetic data and physiological measures from the user, incorporating offline measures such as trainee’s profile information, providing adaptations on controlled elements in the simulation, adjusting feedback content, type, and timing, and using reinforcement learning algorithms.

Perceptual impairment and psychomotor control in virtual laparoscopic surgery

TL;DR: The findings of the study provide further support for the utility of examining strategic gaze behaviour and eye-hand coordination measures to help further the authors' understanding of how experienced surgeons attempt to overcome the perceptual difficulties inherent in the laparoscopic environment.

Development of Expertise in Surgical Training
TL;DR: The attributes of expert surgeons are reviewed, as well as the role of deliberate practice, contextual interference, and distributed practice in the development of expertise, which have direct relevance to surgical training and continuing medical educational courses.

Virtually the same? How impaired sensory information in virtual reality may disrupt vision for action.
TL;DR: The novel perceptual environment of VR may affect vision for action, by shifting users away from a dorsal mode of control, which may create a fundamental disparity between virtual and real-world skills that has important consequences for how the authors understand perception and action in the virtual world.

Bias in meta-analysis detected by a simple, graphical test
TL;DR: Funnel plots, plots of the trials' effect estimates against sample size, are skewed and asymmetrical in the presence of publication bias and other biases Funnel plot asymmetry, measured by regression analysis, predicts discordance of results when meta-analyses are compared with single large trials.

Meta-Analysis in Clinical Trials*
TL;DR: This paper examines eight published reviews each reporting results from several related trials in order to evaluate the efficacy of a certain treatment for a specified medical condition and suggests a simple noniterative procedure for characterizing the distribution of treatment effects in a series of studies.

Quantifying heterogeneity in a meta‐analysis
TL;DR: It is concluded that H and I2, which can usually be calculated for published meta-analyses, are particularly useful summaries of the impact of heterogeneity, and one or both should be presented in publishedMeta-an analyses in preference to the test for heterogeneity.

Empirical evidence of bias. Dimensions of methodological quality associated with estimates of treatment effects in controlled trials.
TL;DR: Empirical evidence is provided that inadequate methodological approaches in controlled trials, particularly those representing poor allocation concealment, are associated with bias.

TL;DR: Study of low methodological quality in which the estimate of quality is incorporated into the meta-analyses can alter the interpretation of the benefit of intervention, whether a scale or component approach is used in the assessment of trial quality.
