“…Instead, gradually increasing difficulty, termed 'shaping' in the behavioural literature, has been suggested as one methodology of training (Gallagher et al 2005). On the other hand, the increments have to be sufficiently large to be enough challenging to give an efficient training (Ali et al 2002). As is noticed in our material, skills at baseline vary between individuals and we could see that some individuals with bad stereoacuity had difficulties in improving their performance score.…”

Abstract.Purpose: To investigate initial learning curves on a virtual reality (VR) eye surgery simulator and whether achieved skills are transferable between tasks.Methods: Thirty‐five medical students were randomized to complete ten iterations on either the VR Caspulorhexis module (group A) or the Cataract navigation training module (group B) and then two iterations on the other module. Learning curves were compared between groups. The second Capsulorhexis video was saved and evaluated with the performance rating tool Objective Structured Assessment of Cataract Surgical Skill (OSACSS). The students’ stereoacuity was examined.Results: Both groups demonstrated significant improvements in performance over the 10 iterations: group A for all parameters analysed including score (p < 0.0001), time (p < 0.0001) and corneal damage (p = 0.0003), group B for time (p < 0.0001), corneal damage (p < 0.0001) but not for score (p = 0.752). Training on one module did not improve performance on the other. Capsulorhexis score correlated significantly with evaluation of the videos using the OSACSS performance rating tool. For stereoacuity < and ≥120 seconds of arc, sum of both modules’ second iteration score was 73.5 and 41.0, respectively (p = 0.062).Conclusion: An initial rapid improvement in performance on a simulator with repeated practice was shown. For capsulorhexis, 10 iterations with only simulator feedback are not enough to reach a plateau for overall score. Skills transfer between modules was not found suggesting benefits from training on both modules. Stereoacuity may be of importance in the recruitment and training of new cataract surgeons. Additional studies are needed to investigate this further. Concurrent validity was found for Capsulorhexis module.

“…To utilize this kind of feedback in VR training, a hand-held stylus is usually attached to the robotic arm, and the forces are translated to the participant through the stylus. This type of set-up has been used to train surgical techniques, 11,12 but has not been used to date in rehabilitation. To feel more realistic force feedback on different fingers and thumb, or throughout the arm, an exoskeleton type device is required.…”

In this paper, the current "state of the art" for virtual reality (VR) applications in the field of motor rehabilitation is reviewed. The paper begins with a brief overview of available equipment options. Next, a discussion of the scientific rationale for use of VR in motor rehabilitation is provided. Finally, the major portion of the paper describes the various VR systems that have been developed for use with patients, and the results of clinical studies reported to date in the literature. Areas covered include stroke rehabilitation (upper and lower extremity training, spatial and perceptual-motor training), acquired brain injury, Parkinson's disease, orthopedic rehabilitation, balance training, wheelchair mobility and functional activities of daily living training, and the newly developing field of telerehabilitation. Four major findings emerge from these studies: (1) people with disabilities appear capable of motor learning within virtual environments; (2) movements learned by people with disabilities in VR transfer to real world equivalent motor tasks in most cases, and in some cases even generalize to other untrained tasks; (3) in the few studies (n = 5) that have compared motor learning in real versus virtual environments, some advantage for VR training has been found in all cases; and (4) no occurrences of cybersickness in impaired populations have been reported to date in experiments where VR has been used to train motor abilities.

“…The 24 influential articles reviewed in this article are organized by year of publication, listed by first author, and described individually below. This study 5 evaluated the impact of training novices to perform a laparoscopic cholecystectomy by using either simple or more complex skills training. After a pretest of basic laparoscopy skills, high-school students were randomly assigned to either low-level or medium-level skills training on a Minimally Invasive Surgical Training-Virtual Reality System.…”

Background Exploring the trends in surgical education research offers insight into concerns, developments, and questions researchers are exploring that are relevant to teaching and learning in surgical specialties. Objective We conducted a review of the surgical education literature published between 2002 and 2012. The purpose was 2-fold: to provide an overview of the most frequently cited articles in the field of surgical education during the last decade and to describe the study designs and themes featured in these articles. Methods Articles were identified through Web of Science by using “surgical education” and “English language” as search terms. Using a feature in Web of Science, we tracked the number of citations of any publication. Of the 800 articles produced by the initial search, we initially selected 23 articles with 45 or more citations, and ultimately chose the 20 articles that were most frequently cited for our analysis. Results Analysis of the most frequently cited articles published in US journals between the years 2002–2012 identified 7 research themes and presented them in order of frequency with which they appear: use of simulation, issues in student/resident assessment, specialty choice, patient safety, team training, clinical competence assessment, and teaching the clinical sciences, with surgical simulation being the central theme. Researchers primarily used descriptive methods. Conclusions Popular themes in surgical education research illuminate the information needs of surgical educators as well as topics of high interest to the surgical community.

Training the novice in laparoscopy

Abstract: Virtual simulation is an effective laparoscopic training method for the novice, providing significant improvement in skill levels over a relatively short period. More challenging training seems to predict greater improvement over time and better final skill levels.
