“…For all considered tasks, the most prominent motion efficiency metrics are time, path length and economy of movements [24,30,31,34]. They are especially important in the tasks which involve touching or grasping objects on the scenario, both with one or two instruments; and that require bi-manual coordination.…”

“…VR simulators allow quantifying tissue damage by collisions' detection, which can be seen as an indicator of the spatial perception of the environment [23]. Where present, this has generated positive validation results as a differentiating metric [24,36,40]. Another quality metricdetection of idle states-has not gained much attention.…”

Training and assessment paradigms for laparoscopic surgical skills are evolving from traditional mentortrainee tutorship towards structured, more objective and safer programs. Accreditation of surgeons requires reaching a consensus on metrics and tasks used to assess surgeons' psychomotor skills. Ongoing development of tracking systems and software Solutions has allowed for the expansión of novel training and assessment means in laparoscopy. The current challenge is to adapt and include these systems within training programs, and to exploit their possibilities for evaluation purposes. This paper describes the state of the art in research on measuring and assessing psychomotor laparoscopic skills. It gives an overview on tracking systems as well as on metrics and advanced statistical and machine learning techniques employed for evaluation purposes. The later ones have a potential to be used as an aid in deciding on the surgical competence level, which is an important aspect when accreditation of the surgeons in particular, and patient safety in general, are considered. The prospective of these methods and tools make them complementary means for surgical assessment of motor skills, especially in the early stages of training. Successful examples such as the Fundamentáis of Laparoscopic Surgery should help drive a paradigm change to structured curricula based on objective parameters. These may improve the accreditation of new surgeons, as 1 To whom correspondence and reprint requests should be addressed at Bioengineering and Telemedicine Centre (GBT), ETSI Telecomunicación, Universidad Politécnica de Madrid (UPM).

“…On the other hand, efficiency, both for the left and the right instruments, as well as Harms to the background are improved along the 8 repetitions and in our opinion they could be still improved with more training sessions. Comparing these results with the mean of experts obtained in [24], novices are not able to reach experts' level just with an 8-repetition training program. Trainees acquire confidence to handle instruments and move them faster, but they still are not able to move them efficiently without damaging the background.…”

Purpose Surgical simulators are currently essential within any laparoscopic training program because they provide a low-stakes, reproducible and reliable environment to acquire basic skills. The purpose of this study is to determine the training learning curve based on different metrics corresponding to Ave tasks included in SINERGIA laparoscopic virtual reality simulator. Methods Thirty medical students without surgical experience participated in the study. Five tasks of SINERGIA were included: Coordination, Navigation, Navigation and touch, Accurate grasping and Coordinated pulling. Each participant was trained in SINERGIA. This training consisted of eight sessions (R1-R8) of the Ave mentioned tasks and was carried out in two consecutive days with four sessions per day. A statistical analysis was made, and the results of Rl, R4 and R8 were pair-wise compared with Wilcoxon signed-rank test. Significance is considered at P value <0.005. Results In total, 84.38 % of the metrics provided by SINER-GIA and included in this study show significant differences when comparing Rl and R8. Metrics are mostly improved in the Arst session of training (75.00 % when Rl and R4 are compared vs. 37.50 % when R4 and R8 are compared). In tasks Coordination and Navigation and touch, all metrics psychomotor skills are improved. On the other hand, Navigation just improves 60 % of the analyzed metrics. Most learning curves show an improvement with better results in the fulfillment of the different tasks. Conclusions Learning curves of metrics that assess the basic psychomotor laparoscopic skills acquired in SINERGIA virtual reality simulator show a faster learning rate during the Arst part of the training. Nevertheless, eight repetitions of the tasks are not enough to acquire all psychomotor skills that can be trained in SINERGIA. Therefore, and based on these results together with previous works, SINERGIA could be used as training tool with a properly designed training program.
