Purpose: Surgeons' adaptability to robotic manipulation remains underexplored. This study evaluated the participants' first-touch robotic training skills using the hinotori surgical robot system and its simulator (hi-Sim) to assess adaptability. Methods: We enrolled 11 robotic surgeons (RS), 13 laparoscopic surgeons (LS), and 15 novices (N). After tutorial and training, participants performed pegboard tasks, camera and clutch operations, energizing operations, and suture sponge tasks on hi-Sim. They also completed a suture ligation task using the hinotori surgical robot system on a suture simulator. Median scores and task completion times were compared. Results: Pegboard task scores were 95.0%, 92.0%, and 91.5% for the RS, LS, and N groups, respectively, with differences between the RS group and LS and N groups. Camera and clutch operation scores were 93.1%, 49.7%, and 89.1%, respectively, showing differences between the RS group and LS and N groups. Energizing operation scores were 90.9%, 85.2%, and 95.0%, respectively, with a significant difference between the LS and N groups. Suture sponge task scores were 90.6%, 43.1%, and 46.2%, respectively, with differences between the RS group and LS and N groups. For the suture ligation task, completion times were 368 s, 666 s, and 1095 s, respectively, indicating differences among groups. Suture scores were 12, 10, and 7 points, respectively, with differences between the RS and N groups. Conclusion: First-touch simulator-based robotic skills were partially influenced by prior robotic surgical experience, while suturing skills were affected by overall surgical experience. Thus, robotic training programs should be tailored to individual adaptability. [ABSTRACT FROM AUTHOR]

Introduction: Surgical autonomy for trainees has remained elusive to quantify. Proportion of active control time (ACT) of a trainee during a robotic case can be used as a broad measure of autonomy. However, this metric lacks in the granular detail of quantifying at what specific steps trainees were actively participating. We aim to quantify trainee involvement during robotic-assisted hiatal hernia repair at a task-specific level. Methods: We performed a retrospective review of surgical performance data from robotic-assisted hiatal hernia repairs performed. These cases were segmented into 5 tasks by AI-assisted annotation with human review. The segmented tasks included: hiatal dissection, gastric fundus mobilization, mediastinal dissection, cruroplasty and fundoplication. Tasks were excluded if video segmentation of tasks was incorrect. During each task, ACT was recorded for resident, fellow and attending. Resident and fellow ACT per task was compared using the Mann–Whitney U test. Results: Residents had the highest %ACT in the hiatal dissection (53%), gastric fundus mobilization (84%) and fundoplication (57%) tasks. Fellows had greater than 80% ACT in all 5 tasks, with the highest %ACT in the gastric fundus mobilization (100%) and hiatal dissection (88%). There was a significant difference between resident and fellow ACT during mediastinal dissection and cruroplasty. Conclusions: This study demonstrates how objective performance metrics and automated case segmentation can quantify trainee participation at a task-specific level. By utilizing data afforded by a robotic surgery platform, we are able to provide an objective and automated form of assessment with minimal impact on the workflow of attendings and residents. Our findings can serve to inform residents on what steps they can expect to be involved in during the procedure, appropriate to their PGY level. With this task-level data, we can provide a roadmap for trainee progression to achieve full surgical autonomy. [ABSTRACT FROM AUTHOR]

Objectives: Robotic-assisted surgery (RAS) is a minimally invasive technique practiced in multiple specialties. Standard training is essential for the acquisition of RAS skills. The cost of RAS is considered to be high, which makes it a burden for institutes and unaffordable for patients. This systematic literature review (SLR) focused on the various RAS training methods applied in different surgical specialties, as well as the cost elements of RAS, and was to summarize the opportunities and challenges associated with scaling up RAS. Methods: An SLR was carried out based on the Preferred Reporting Items for Systematic reviews and Meta-Analyses reporting guidelines. The PubMed, EBSCO, and Scopus databases were searched for reports from January 2018 through January 2024. Full-text reviews and research articles in the English language from Asia-Pacific countries were included. Articles that outlined training and costs associated with RAS were chosen. Results: The most common training system is the da Vinci system. The simulation technique, which includes dry-lab, wet-lab, and virtual reality training, was found to be a common and important practice. The cost of RAS encompasses the installation and maintenance costs of the robotic system, the operation theatre rent, personnel cost, surgical instrument and material cost, and other miscellaneous charges. The synthesis of SLR revealed the challenges and opportunities regarding RAS training and cost. Conclusions: The results of this SLR will help stakeholders such as decision-makers, influencers, and end users of RAS to understand the significance of training and cost in scaling up RAS from a managerial perspective. For any healthcare innovation to reach a vast population, cost-effectiveness and standard training are crucial.

Background: Early phase research suggests that physiotherapy paired with use of robotic walking aids provides a novel opportunity for children with severe mobility challenges to experience active walking. The Trexo Plus is a pediatric lower limb exoskeleton mounted on a wheeled walker frame, and is adjustable to fit a child's positional and gait requirements. It guides and powers the child's leg movements in a way that is individualized to their movement potential and upright support needs, and can provide progressive challenges for walking within a physiotherapy-based motor learning treatment paradigm. Methods: This protocol outlines a single group mixed-methods study that assesses the feasibility of physiotherapy-assisted overground Trexo use in school and outpatient settings during a 6-week physiotherapy block. Children ages 3-6 years (n = 10; cerebral palsy or related disorder, Gross Motor Function Classification System level IV) will be recruited by circle of care invitations to participate. Study indicators/outcomes will focus on evaluation of: (i) clinical feasibility, safety, and acceptability of intervention; (ii) prepost intervention motor/functional outcomes; (iii) pre-post intervention brain structure characterization and resting state brain connectivity; (iv) muscle activity characterization during Trexo-assisted gait and natural assisted gait; (v) heart rate during Trexo-assisted gait and natural assisted gait; and (vi) user experience and perceptions of physiotherapists, children, and parents. Discussion: This will be the first study to investigate feasibility indicators, outcomes, and experiences of Trexo-based physiotherapy in a school and outpatient context with children who have mobility challenges. It will explore the possibility of experience-dependent neuroplasticity in the context of gait rehabilitation, as well as associated functional and muscular outcomes. Finally, the study will address important questions about clinical utility and future adoption of the device from the physiotherapists' perspective, comfort and engagement from the children's perspective, and the impressions of parents about the value of introducing this technology as an early intervention.

Understanding alignment and gap balancing in Total Knee Arthroplasty (TKA) can be challenging for trainee and experienced orthopedic surgeons. Traditional learning methods may not effectively translate to real-life scenarios. The advent of advanced technologies like robotic surgery and navigation systems has revolutionized intraoperative understanding of gap balancing techniques. This trial aims to investigate the effectiveness of robotic TKA planning software in educating trainees about alignment and ligament balancing. We hypothesize that a single session with the software will significantly enhance trainees' understanding of these techniques. This UK-based single-center, two-arm, group parallel randomized controlled trial was conducted during a national robotic arthroplasty symposium. It aims to evaluate the effect of robotic knee arthroplasty software training on understanding TKA alignment and gap balancing principles using Multiple Choice Questions (MCQs). The MCQ test was crafted based on established guidelines from a different institution with expert consensus in the field. Our study revealed that baseline knowledge of gap balancing and alignment principles was generally low among all participants. However, the intervention group, which received comprehensive robotic software training, demonstrated a significant improvement in their MCQ scores compared to the control group, which did not undergo the training. In conclusion, our study demonstrates that robotic arthroplasty software training significantly improves the understanding of TKA alignment and balancing principles among orthopedic trainees.

Background and objectivesRobotic approach in colorectal surgery is rapidly gaining interest, particularly in the context of rectal cancer resection. Despite economic barriers, substantial proliferation of robotic colorectal procedures has been observed throughout Latin America. However, there is a lack of data regarding intraoperative and early postoperative outcomes, as well as oncological and long-term results. This systematic review aims to provide an overview of the surgical outcomes of robotic-assisted colorectal approaches across Latin America.Material and methodsA systematic literature search of electronic databases, including PubMed, LILACS, Scopus, Cochrane Library and Scielo, was performed and reported in line with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The main target of the literature search was studies that reported outcomes of colorectal robotic surgery in Latin America.ResultsA total of 9,694 published articles were identified from the initial search. Nine thousand six hundred thirty-six publications were excluded after title and abstract review and removal of duplicates. Fifty-eight articles were thoroughly reviewed, and 11 studies met the inclusion criteria. The critical appraisal of study quality (biases risk assessment) was performed according to the Joanna Briggs Institute (JBI) Manual for Evidence Synthesis. In general, the overall study quality was poor. Of the 11 studies included in the analysis, ten addressed intraoperative and early postoperative outcomes, seven addressed oncological/pathological outcomes, and just one addressed long-term outcomes. Ten studies evaluated intraoperative and early postoperative outcomes, encompassing a total of 425 patients, the majority of whom were diagnosed with colorectal cancer. Morbidity rates exhibited a range between 0% and 45.9%, while mortality ranged from 0% to 2.5%.ConclusionFew studies have been published addressing intraoperative, postoperative, pathological, and oncological outcomes of robotic colorectal surgery in this region. Undoubtedly, there are unique challenges not encountered by developed countries, including economic obstacles in establishing structured training programmes and high-quality centres for the development of robotic surgery. Further studies are needed to assess the real extent of robotic surgery in the region and its results.Systematic Review Registrationhttps://www.crd.york.ac.uk/, PROSPERO (CRD42023494112).

Objectives: Transcranial direct current stimulation and robotic therapy (RT) are two modalities in neurorehabilitation for the improvement of upper limb function in stroke patients. However, the additional effects of the concurrent application of these two techniques compared to RT alone on upper limb function in stroke patients have not been studied yet. We analyzed the effectiveness of concurrent tDCS and RT compared to RT alone on upper limb motor function in stroke patients. Methods: A systematic search of PubMed, Scopus, Web of Science, CENTRAL, EMBASE, and Physiotherapy Evidence Database was performed from 2000 to January 1, 2021. The quality of the included studies was evaluated using the Cochrane risk-of-bias assessment tool. All statistical analyses were performed in STATA software, version 14, and the Mean±SD was used as the pooled statistics. Results: The result showed that concurrent tDCS and RT had moderate but non-significant pooled effect sizes for upper limb Fugl-Meyer assessment (SMD=0.31, 95% CI, -0.20%, 0.83%, I2=84.1%). Discussion: According to the results of this study, no difference was obtained in the efficacy of concurrent tDCS and RT compared to RT alone on upper limb function in stroke survivors.

Background: Evidence for how to best train surgical residents for robotic bariatric procedures is lacking. We developed targeted educational resources to promote progression on the robotic bariatric learning curve. This study aimed to characterize the effect of resources on resident participation in robotic bariatric procedures. Methods: Performance metrics from the da Vinci Surgical System were retrospectively reviewed for sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) cases involving general surgery trainees with a single robotic bariatric surgeon. Pictorial case guides and narrated operative videos were developed for these procedures and disseminated to trainees. Percent active control time (%ACT)—amount of trainee console time spent in active instrument manipulations over total active time from both consoles—was the primary outcome measure following dissemination. One-way ANOVA, Student's t-tests, and Pearson correlations were applied. Results: From September 2020 to July 2021, 50 cases (54% SG, 46% RYGB) involving 14 unique trainees (PGY1-PGY5) were included. From November 2021 to May 2022 following dissemination, 29 cases (34% SG, 66% RYGB) involving 8 unique trainees were included. Mean %ACT significantly increased across most trainee groups following resource distribution: 21% versus 38% for PGY3s (p = 0.087), 32% versus 45% for PGY4s (p = 0.0009), and 38% versus 57% for PGY5s (p = 0.0015) and remained significant when stratified by case type. Progressive trainee %ACT was not associated with total active time for SG cases before or after intervention (pre r = − 0.0019, p = 0.9; post r = − 0.039, p = 0.9). It was moderately positively associated with total active time for RYGB cases before dissemination (r = 0.46, p = 0.027) but lost this association following intervention (r = 0.16, p = 0.5). Conclusion: Use of targeted educational resources promoted increases in trainee participation in robotic bariatric procedures with more time spent actively operating at the console. As educators continue to develop robotic training curricula, efforts should include high-quality resource development for other sub-specialty procedures. Future work will examine the impact of increased trainee participation on clinical and patient outcomes. [ABSTRACT FROM AUTHOR]

While laparoscopic simulation-based training is a well-established component of general surgery training, no such requirement or standardized curriculum exists for robotic surgery. Furthermore, there is a lack of high-fidelity electrocautery simulation training exercises in the literature. Using Messick's validity framework, we sought to determine the content, response process, internal content and construct validity of a novel inanimate tissue model that utilizes electrocautery for potential incorporation in such curricula. A multi-institutional, prospective study involving medical students (MS) and general surgery residents (PGY1-3) was conducted. Participants performed an exercise using a biotissue bowel model on the da Vinci Xi robotic console during which they created an enterotomy using electrocautery, followed by approximation with interrupted sutures. Participant performance was recorded and then scored by crowd-sourced assessors of technical skill, along with three of the authors. Construct validity was determined via difference in Global Evaluative Assessment of Robotic Skills (GEARS) score, time to completion, and total number of errors between the two cohorts. Upon completion of the exercise, participants were surveyed on their perception of the exercise and its impact on their robotic training to determine content validity. 31 participants were enrolled and separated into two cohorts: MS + PGY1 vs. PGY2-3. Time spent on the robotic trainer (0.8 vs. 8.13 h, p = 0.002), number of bedside robotic assists (5.7 vs. 14.8, p < 0.001), and number of robotic cases as primary surgeon (0.3 vs. 13.1, p < 0.001) were statistically significant between the two groups. Differences in GEARS scores (18.5 vs. 19.9, p = 0.001), time to completion (26.1 vs. 14.4 min, p < 0.001), and total errors (21.5 vs. 11.9, p = 0.018) between the groups were statistically significant as well. Of the 23 participants that completed the post-exercise survey, 87% and 91.3% reported improvement in robotic surgical ability and confidence, respectively. On a 10-point Likert scale, respondents rated the realism of the exercise 7.5, educational benefit 9.1, and effectiveness in teaching robotic skills 8.7. Controlling for the upfront investment of certain training materials, each exercise iteration cost ~ $30. This study confirmed the content, response process, internal structure and construct validity of a novel, high-fidelity and cost-effective inanimate tissue exercise which successfully incorporates electrocautery. Consideration should be given to its addition to robotic surgery training programs. [ABSTRACT FROM AUTHOR]

Trainee participation and progression in robotic general surgery remain poorly defined. Computer-assisted technology offers the potential to provide and track objective performance metrics. In this study, we aimed to validate the use of a novel metric—active control time (ACT)—for assessing trainee participation in robotic-assisted cases. Performance data from da Vinci Surgical Systems was retrospectively analyzed for all robotic cases involving trainees with a single minimally invasive surgeon over 10 months. The primary outcome metric was percent ACT—the amount of trainee console time spent in active system manipulations over total active time from both consoles. Kruskal–Wallis and Mann–Whitney U statistical tests were applied in analyses. A total of 123 robotic cases with 18 general surgery residents and 1 fellow were included. Of these, 56 were categorized as complex. Median %ACT was statistically different between trainee levels for all case types taken in aggregate (PGY1s 3.0% [IQR 2–14%], PGY3s 32% [IQR 27–66%], PGY4s 42% [IQR 26–52%], PGY5s 50% [IQR 28–70%], and fellow 61% [IQR 41–85%], p = < 0.0001). When stratified by complexity, median %ACT was higher in standard versus complex cases for PGY5 (60% vs. 36%, p = 0.0002) and fellow groups (74% vs. 47%, p = 0.0045). In this study, we demonstrated an increase in %ACT with trainee level and with standard versus complex robotic cases. These findings are consistent with hypotheses, providing validity evidence for ACT as an objective measurement of trainee participation in robotic-assisted cases. Future studies will aim to define task-specific ACT to guide further robotic training and performance assessments. [ABSTRACT FROM AUTHOR]

Background and Objectives: Robotic surgical systems have rapidly become integrated into colorectal surgery practice in recent years, particularly for rectal resections, where the advantages of robotic platforms over conventional laparoscopy are more pronounced. However, as with any technological advancement, the initial high costs can be a limiting factor, leading to unequal health service access, especially in middle- and lower-income countries. Materials and Method: A narrative review was conducted with the objective of providing an overview of the escalating adoption, current training programmes, and certification process of robotic colorectal surgery in Brazil. Results: Brazil has witnessed a rapid increase in robotic platforms in recent years. Currently, there are 106 robotic systems installed nationwide. However, approximately 60% of the medical facilities which adopted robotic platforms are in the Southeast region, which is both the most populous and economically prosperous in the country. The Brazilian Society of Coloproctology recently established clear rules for the training programme and certification of colorectal surgeons in robotic surgery. The key components of the training encompass theoretical content, virtual robotic simulation, observation, assistance, and supervised procedures in colorectal surgery. Although the training parameters are well established, no colorectal surgery residency programme in Brazil has yet integrated the teaching and training of robotic surgery into its curriculum. Thus far, the training process has been led by private institutions and the industry. Conclusion: Despite the fast spread of robotic platforms across Brazil, several challenges still need to be addressed to democratise training and promote the widespread use of these platforms. It is crucial to tackle these obstacles to achieve greater integration of robotic technology in colorectal surgery throughout the country. [ABSTRACT FROM AUTHOR]

Video-based instructional tools are an important emerging component of robotic surgical education. However, there is a paucity of literature on the structure of video as an instructional tool in robotic surgery. This paper reviews the literature on video-based instructional tools and provides a series of recommendations for the structure of a video- based training tool in robotic surgery. Key educational aspects to consider in designing a video training tool are student engagement, content validity, cognitive load, and active learning. Key recommendations for structure of instructional videos are that videos should be short, presented in modular blocks with appropriate narration and engagement strategies. [ABSTRACT FROM AUTHOR]

There is currently no standardized robotic surgery training program in General Surgery Residency. RAST involves three modules: ergonomics, psychomotor, and procedural. This study aimed to report the results of module 1, which assessed the responsiveness of 27 PGY (postgraduate year) 1–5 general surgery residents (GSRs) to simulated patient cart docking, and to evaluate the residents' perception of the educational environment from 2021 to 2022. GSRs prepared with pre-training educational video and multiple-choice questions test (MCQs). Faculty provided one-on-one resident hands-on training and testing. Nine proficiency criteria (deploy cart; boom control; driving cart; docking camera port; targeting anatomy; flex joints; clearance joints; port nozzles; emergency undocking) were assessed with five-point Likert scale. A validated 50-item Dundee Ready Educational Environment Measure (DREEM) inventory was used by GSRs to assess the educational environment. Mean MCQ scores: (90.6 ± 16.1 PGY1), (80.2 ± 18.1PGY2), (91.7 ± 16.5 PGY3) and (PGY4, 86.8 ± 18.1 PGY5) (ANOVA test; p = 0.885). Hands-on docking time decreased at testing when compared to base line: median 17.5 (range 15–20) min vs. 9.5 (range 8–11). Mean hands-on testing score was 4.75 ± 0.29 PGY1; 5.0 ± 0 PGY2 and PGY3, 4.78 ± 0.13 PGY4, and 4.93 ± 0.1 PGY5 (ANOVA test; p = 0.095). No correlation was found between pre-course MCQ score and hands-on training score (Pearson correlation coefficient = − 0.359; p = 0.066). There was no difference in the hands-on scores stratified by PGY. The overall DREEM score was 167.1 ± 16.9 with CAC = 0.908 (excellent internal consistency). Patient cart training impacted the responsiveness of GSRs with 54% docking time reduction and no differences in hands-on testing scores among PGYs with a highly positive perception.

Children with cerebral palsy (CP) have sensorimotor impairments including weakness, spasticity, reduced motor control and sensory deficits. Proprioceptive dysfunction compounds the decreased motor control and mobility. The aims of this paper were to (1) examine proprioceptive deficit of lower extremities of children with CP; (2) study improvement in proprioception and clinical impairments through robotic ankle training (RAT). Eight children with CP participated in a 6-week RAT with pre and post ankle proprioception, clinical, biomechanical assessment compared to the assessment of eight typically developing children (TDC). The children with CP participated in passive stretching (20 min/session) and active movement training (20 to 30 min/session) using an ankle rehabilitation robot (3 sessions/week over 6 weeks, total of 18 sessions). Proprioceptive acuity measured as the plantar and dorsi-flexion motion at which the children recognized the movement was 3.60 ± 2.28° in dorsiflexion and −3.72 ± 2.38° in plantar flexion for the CP group, inferior to that of the TDC group's 0.94 ± 0.43° in dorsiflexion (p = 0.027) and −0.86 ± 0.48° in plantar flexion (p = 0.012). After training, ankle motor and sensory functions were improved in children with CP, with the dorsiflexion strength increased from 3.61 ± 3.75 Nm to 7.48 ± 2.75 Nm (p = 0.018) and plantar flexion strength increased from −11.89 ± 7.04 Nm to −17.61 ± 6.81 Nm after training (p = 0.043). The dorsiflexion AROM increased from 5.58 ± 13.18° to 15.97 ± 11.21° (p = 0.028). The proprioceptive acuity showed a trend of decline to 3.08 ± 2.07° in dorsiflexion and to −2.59 ± 1.94° in plantar flexion (p > 0.05). The RAT is a promising intervention for children with CP to improve sensorimotor functions of the lower extremities. It provided an interactive and motivating training to engage children with CP in rehabilitation to improve clinical and sensorimotor performance. [ABSTRACT FROM AUTHOR]

Background: Robot assisted laparoscopic abdominal wall surgery (RAWS) has seen a rapid adoption in recent years. The safe introduction of the robot platform in the treatment of abdominal wall hernias is important to safeguard the patient from harm during the learning curve. The scope of this paper is to describe the current European training curriculum in RAWS.Methods and Analysis: The pathway to competence in RAWS will depend on the robot platform, experience in other abdominal procedures (novice to expert) and experience in the abdominal wall repair techniques. An overview of the learning curve effect in the initial case series of several early adopters in RAWS was reviewed. In European centres, current training for surgeons wanting to adopt RAWS is managed by the specific technology-based training organized by the company providing the robot. It consists of four phases where phases I and II are preclinical, while phases III and IV focus on the introduction of the robotic platform into surgical practice.Conclusion: On behalf of the Robotic Surgery Task Force of the European Hernia Society (EHS) we believe that the EHS should play an important role in the clinical phases III and IV training. Courses organized in collaboration with the robot provider on relevant surgical anatomy of the abdominal wall and procedural steps in complex abdominal wall reconstruction like transversus abdominis release are essential. Whereas the robot provider should be responsible for the preclinical phases I and II to gain familiarity in the specific robot platform.

Since 2000, robotic-assisted surgery has rapidly expanded into almost every surgical sub-specialty. Despite the popularity of robotic surgery across the United States, a national consensus for standardized training and education of robotic surgeons or surgical teams remains absent. In this quality improvement initiative, a novel, stepwise iterative Robotic Assistant Surgical Training (RAST) curriculum was developed to broaden and standardize robotic bedside assistant training. Thirteen voluntary participants, capable of fulfilling the bedside assistant role, were evaluated to determine if RAST enhanced the learner's self-perceived level of confidence and comfort in their role as bedside assistant. A pre- and post-RAST training survey and a between-stages repeated-measures survey were conducted. All learner participants reported statistically significant increases in confidence and comfort after RAST training, (p = < 0.001), and between each stage, F (2, 24 = 60.47, p <.001; η p 2 = 0.834). Participant feedback regarding curriculum improvement was obtained, suggesting the desire for more training and practice, in smaller groups of 2–3 participants. One hundred percent of participants felt RAST was beneficial and that it should be implemented as standardized training during onboarding for all robotic bedside assistants. Thus, a standardized, stepwise iterative robotic bedside assistant curriculum increases learner preparedness, comfort, and confidence, safely away from the patient bedside. [ABSTRACT FROM AUTHOR]

Objective: Robot-assisted neuro-rehabilitation therapy plays a central role in upper extremity recovery of stroke. However, the efficacy of robotic training on the upper extremity is not yet well defined, and little attention has been devoted to its potential effect on the lower extremity. The aim of this study was to compare the efficacy of robot-assisted training and therapist-mediated enhanced upper extremity therapy on the upper and lower extremities. Methods: A randomized clinical trial involving 172 stroke survivors was conducted in China. All participants received either robot-assisted training or enhanced upper extremity therapy for 3 weeks. Fugl-Meyer assessment upper extremity subscale (FMA-UE), Fugl-Meyer assessment lower extremity subscale (FMA-LE), and Modified Barthel Index were administered at baseline, mid-treatment (1 week after treatment start), and post-treatment. Results: Participants in the robot-assisted training group showed a significant improvement in the hemiplegia extremity, which was non-inferior to the enhanced upper extremity therapy group in FMA-UE (p < 0.05), while suggesting greater motor recovery of lower extremity in FMA-LE (p < 0.05) compared with the enhanced upper extremity therapy group. A marked increase in Modified Barthel Index was observed within groups; however, no significant difference was found between groups. Conclusion: Robot-assisted training is non-inferior but not better in reducing impairment of the upper extremity and appears to be superior in reducing impairment of the lower extremity compared with enhanced upper extremity therapy for stroke survivors. LAY ABSTRACT Although post-stroke robot-assisted training of the upper extremity has been widely studied, its efficacy is not yet well defined, and its effects on the lower extremity are unknown. This study aimed to evaluate the effects of upper extremity robot-assisted training on the upper and lower extremities in stroke survivors. Robot-assisted training is non-inferior in improving the function of the upper extremity and superior in improving the function of the lower extremity compared with enhanced upper extremity therapy. Robot-assisted training can be used for functional recovery of the upper and lower extremities in stroke survivors.

Robotic Surgery is getting widely spread and applied to more and more clinical cases due to its advantages compared to open surgery, for both the patients and surgeons. However, Robotic Surgery requires a different set of skills and learning compared to open and also laparoscopic surgery. Tele-operation for a robotic system with hand controllers, the delay in the hand commands to be translated into robotic movements, slowness of the robotic movements, remote 2D or 3D vision of the actual operation, and lack of haptic feedback are some of the challenges that Robotic Surgery poses. Surgeons need to go through an intensive training for Robotic Surgery, and the learning and skill development continues throughout their early professional years. Despite the importance of training for Robotic Surgery, there are not yet dedicated, low-cost, and widespread training platforms; rather, surgeons mostly train with the same Robotic Surgery system they use in surgery; hence institutions need to invest on a separate surgical setup for training purposes. This is expensive for the institutions, it provides very limited access to the surgeons for training, and very limited, if any, access to researchers for experimentation. To address these, we have developed in our laboratory a low-cost, and experimental Robotic Surgery Trainer. This setup replicates the challenges that a Robotic Surgery system poses and further provides widespread access through internet connected control of the actual physical system. The overall system is composed of equipment that a standard engineering laboratory can afford. In this paper, we introduce the Robotic Surgery Training System and explain its development, parts, and functionality.

A virtual reality (VR) curriculum performed on the da Vinci Simulation System (DVSS) was previously shown to be effective in training fellows. The dV-Trainer is a separate platform with similar features to the da Vinci console, but its efficacy and utility versus the DVSS simulator are not well known. A mastery-based VR curriculum was completed by surgical fellows on the DVSS (2014-2016) and on the dV-Trainer (2016-2018) at a large academic center. Pre-test/post-test scores were used to evaluate performance between the two groups. Data was collected prospectively. Forty-six fellows enrolled in the curriculum: surgical oncology (n =31), hepatobiliary (n =5), head/neck (n =4), endocrine (n =2), cardiothoracic (n =2), gynecology (n =1) and transplant surgery (n =1). Twenty-four used the DVSS and twenty-two used the dV-Trainer. Compared to the DVSS, the dV-Trainer was associated with lower scores on 2 of 3 VR modules in the pre-test (P =0.027, P <0.001, respectively) and post-test (P =0.021, P <0.001, respectively). Fellows in the dV-Trainer era scored lower on inanimate drills as well. Average VR curriculum score was lower on the dV-Trainer (71.3% vs 83.34%, P <0.001). dV-Trainer users spent more time completing the pre-test and post-test; however, overall simulator time to complete the curriculum was not significantly different (297 vs 231 minutes, P =0.142). Both groups showed improvement in scores after completion of the VR curriculum. The dV-Trainer simulator allows for more usability outside the operating room to complete VR modules; however, the DVSS simulator group outperformed the dV-Trainer group on the post-test.

Robotic colorectal surgery has been touted as a possible way to overcome the limitations of laparoscopic surgery and has shown promise in rectal resections, thus shifting traditional open surgeons to a minimally invasive approach. The safety, efficacy, and learning curve have been established for most colorectal applications. With this and a robust sales and marketing model, utilization of the robot for colorectal surgery continues to grow steadily. However, this disruptive technology still requires standards for training, privileging and credentialing, and safe implementation into clinical practice. [ABSTRACT FROM AUTHOR]

Introduction: Trainees underestimate the amount of operative autonomy they receive, whereas faculty overestimate; this has not been studied in robotics. We aimed to assess the perceptions and expectations of our general surgery trainees and faculty on robotic console participation in academic surgery.Methods: A survey was administered to general surgery robotic faculty and trainees eligible to sit at the console. Participants estimated the average percentage of trainee console participation time (CPT) per case for robotic cholecystectomies (CCY) and inguinal hernia repairs (IHR) from January to June 2019. Trainees were additionally asked what CPT they expected according to their training level (novice or senior). Expected CPTs were compared to actual CPTs extracted from robotic console logs during the same time frame.Results: Survey response rate was 80% for faculty (4 of 5) and 65% for trainees (15 of 23). Novices expected a higher CPT than they perceived in CCY (42.8% ± 14.8% vs 19.0% ± 17.2%, p = 0.03) and IHR (36.1% ± 17.6% vs. 10.7% ± 13.7%, p = 0.01), but in actuality, they did more CPT than perceived (by 34.9% in CCY, p < 0.01; 14% in IHR, p = 0.10). Senior trainees accurately perceived their CPT in IHR, but expected a higher CPT by 15.9% (p = 0.04). In CCY, seniors perceived a 23.8% higher CPT than in reality (p = 0.04). Faculty generally overperceived trainee CPT by 12.8-16.3% (p > 0.05). Compared to faculty, novices perceived lower CPTs in both CCY by 29.9% (p = 0.16) and IHR by 26.8% (p = 0.07), but seniors tended to agree with the faculty-perceived CPTs (p > 0.05).Conclusion: Our robotic trainees expect to do more on the console than they perceive. Faculty think they allow their trainees more participation than in reality. Compared to faculty perception, novice trainees perceive a much lower level of trainee participation than senior trainees do. Expectation setting and standardizing learning curves are important for robotic surgery training. [ABSTRACT FROM AUTHOR]

Background and Objectives: Gait disorders represent one of the most disabling aspects in multiple sclerosis (MS) that strongly influence patient quality of life. The improvement of walking ability is a primary goal for rehabilitation treatment. The aim of this study is to evaluate the effectiveness of robot-assisted gait training (RAGT) in association with physiotherapy treatment in patients affected by MS in comparison with ground conventional gait training. Study design: Randomized controlled crossover trial. Materials and Methods: Twenty-seven participants affected by MS with EDSS scores between 3.5 and 7 were enrolled, of whom seventeen completed the study. They received five training sessions per week over five weeks of conventional gait training with (experimental group) or without (control group) the inclusion of RAGT. The patients were prospectively evaluated before and after the first treatment session and, after the crossover phase, before and after the second treatment session. The evaluation was based on the 25-foot walk test (25FW, main outcome), 6 min walk test (6MWT), Tinetti Test, Modified Ashworth Scale, and modified Motricity Index for lower limbs. We also measured disability parameters using Functional Independence Measure and Quality of Life Index, and instrumental kinematic and gait parameters: knee extensor strength, double-time support, step length ratio; 17 patients reached the final evaluation. Results: Both groups significantly improved on gait parameters, motor abilities, and autonomy recovery in daily living activities with generally better results of RAGT over control treatment. In particular, the RAGT group improved more than control group in the 25FW (p = 0.004) and the 6MWT (p = 0.022). Conclusions: RAGT is a valid treatment option that in association with physiotherapy could induce positive effects in MS-correlated gait disorders. Our results showed greater effectiveness in recovering gait speed and resistance than conventional gait training. [ABSTRACT FROM AUTHOR]

As robotic surgery has become more widespread, early exposure to the robotic platform is becoming increasingly important, not only to graduate medical education, but also for medical students pursuing surgical residency. In an effort to orient students to robotic technology and decrease the learning curve for what is likely to become an integral part of residency training, we created a formal, elective robotic surgery curriculum for senior medical students. Throughout this 2-week fourth year rotation, students completed online training modules and assessment; mastered exercises on the simulator system related to the console, camera, energy, dexterity, and suturing skills; attended didactics; utilized the dual console during one-on-one simulation lab sessions with attending robotic surgery experts; and translated new skills to biotissue anastomoses as well as bedside-assisting in the operating room. During cases, students were able to have more meaningful observation experiences, recognizing the significance of various robotic approaches employed and utilization of specific instruments. Future aims of this rotation will assess student experience as it impacts readiness for surgical residency. [ABSTRACT FROM AUTHOR]

Introduction: With increased demands on surgeon productivity and outcomes, residency robotics training increasingly relies on simulations. The objective of this study is to assess the validity and effectiveness of an ex vivo porcine training model as a useful tool to improve surgical skill and confidence with robot-assisted partial nephrectomy (RAPN) among urology residents. Methods: A 2.5 cm circular area of ex vivo porcine kidneys was marked as the area of the tumor. Tumor excision and renorrhaphy was performed by trainees using a da Vinci Si robot. All residents ranging from postgraduate year (PGY) 2 to 5 participated in four training sessions during the 2017 to 2018 academic year. Each session was videorecorded and scored using the global evaluative assessment of robotic skills (GEARS) by faculty members. Results: Twelve residents completed the program. Initial mean GEARS score was 16.7 and improved by +1.4 with each subsequent session (p = 0.008). Initial mean excision, renorrhaphy, and total times were 8.2, 13.9, and 22.1 minutes, which improved by 1.6, 2.0, and 3.6 minutes, respectively (all p < 0.001). Residents' confidence at performing RAPN and robotic surgery increased after completing the courses (p = 0.012 and p < 0.001, respectively). Overall, residents rated that this program has greatly contributed to their skill (4/5) and confidence (4.1/5) in robotic surgery. Conclusions: An ex vivo porcine simulation model for RAPN and robotic surgery provides measurable improvement in GEARS score and reduction in procedural time, although significant differences for all PGY levels need to be confirmed with larger study participation. Adoption of this simulation in a urology residency curriculum may improve residents' skill and confidence in robotic surgery. [ABSTRACT FROM AUTHOR]

Objective: The purpose of this study was to evaluate a new tissue model and to conduct a questionnaire survey to assess its feasibility for robot-assisted radical hysterectomy, colpotomy, and pelvic lymph node dissection training. Methods: Sixteen gynecologists (12 males, 4 females; mean age: 47.1 years; all attending doctors with an average experience of 9.3 robot-assisted surgeries) were trained in robot-assisted radical hysterectomy, colpotomy, and pelvic lymphadenectomy using a new uterine and pelvic lymph node model (mainly composed of PVA) from Fasotec Inc. The participants were trained by the author using a dual console. They performed all surgical procedures following the author's instructions. The time required for completion of the surgeries was measured. The surgical skills of the participants were evaluated by the author using the operative performance rating scale recommended by the American College of Surgeons. After training, the participants answered a questionnaire for the assessment of the model and the training using a 5-point Likert scale. Results: We found that the mean time taken for radical hysterectomy, colpotomy, and pelvic lymphadenectomy was 57.3 minutes (range: 45-75 minutes), 12.2 minutes (range: 8-17 minutes), and 60.7 minutes (range: 45-70 minutes), respectively; the total time taken was 136.5 minutes (range: 98-162 minutes). The questionnaire survey revealed that this model followed pelvic anatomy and was practically trainable. Conclusion: This is the first report of a tissue model relevant to the uterus and the pelvic lymph nodes, and robot-assisted training using this model was considered effective.

Background: The frequency of robotic-assisted bariatric surgery has been on the rise. An increasing number of fellowship programs have adopted robotic surgery as part of the curriculum. Our aim was to compare technical efficiency of a surgeon during the first year of practice after completing an advanced minimally invasive fellowship with a mentor surgeon. Methods: A systematic review of a prospectively maintained database was performed of consecutive patients undergoing robotic-assisted sleeve gastrectomy between 2015 and 2019 at a tertiary-care bariatric center (mentor group) and between 2018 and 2019 at a semi-academic community-based bariatric program (mentee 1 group) and 2019–2020 at a tertiary-care academic center (mentee 2 group). Results: 257 patients in the mentor group, 45 patients in the mentee 1 group, and 11 patients in the mentee 2 group were included. The mentee operative times during the first year in practice were significantly faster than the mentor's times in the first three (mentee 1 group) and two (mentee 2 group) years (P < 0.05) but remained significantly longer than the mentor's times in the last two (mentee 1 group) and one (mentee 2 group) years (P < 0.05). There was no significant difference in venothromboembolic events (P = 0.89) or readmission rates (P = 0.93). The mean length of stay was 1.8 ± 0.5 days, 1.3 ± 0.5 days, and 1.5 ± 0.5 days in the mentor, mentee 1, and mentee 2 groups, respectively (P < 0.0001). There were no reoperations, conversion to laparoscopy or open, no staple line leaks, strictures, or deaths in any group. Conclusions: This is one of the first series to show that the robotic platform can safely be taught and may translate into outcomes consistent with surgeons with more experience while mitigating the learning curve as early as the first year in practice. Long-term follow-up of mentees will be necessary to assess the evolution of fellowship training and outcomes. [ABSTRACT FROM AUTHOR]

While robotic surgery has grown in popularity and scope over the past decade, there is a persistent need for simulation-based training as surgeons adapt from the working at the bedside to the immersive and multisensory tasks at the console. From dry laboratory to virtual reality (VR) environments, simulation can be used to train surgeons in basic tasks, complex operative steps, and coordination of whole operations with members of the entire operating room (OR) staff. By integrating simulation into mentored training programs, surgeons can reduce the number of cases required to master a complex operation. Future VR based simulation will become essential to the adaptation of the surgical workforce to new technologies and adoption of emerging robotic platforms. Ultimately, robotic simulation will set standards for credentialing of new surgeons. [ABSTRACT FROM AUTHOR]

Abstract Background The use of robotic trainers has increased with the aim of improving gait function in patients with limitations. Nevertheless, there is an absence of studies that deeply describe detailed guidelines of how to correctly implement robot-based treatments for gait rehabilitation. This contribution proposes an accurate robot-based training program for gait rehabilitation of pediatric population with Cerebral Palsy (CP). Methods The program is focused on the achievement of some specifications defined by the International Classification of Functioning, Disability and Health framework, Children and Youth version (ICF-CY). It is framed on 16 non-consecutive sessions where motor control, strength and power exercises of lower limbs are performed in parallel with a postural control strategy. A clinical evaluation with four pediatric patients with CP using the CPWalker robotic platform is presented. Results The preliminary evaluation with patients with CP shows improvements in several aspects as strength (74.03 ± 40.20%), mean velocity (21.46 ± 33.79%), step length (17.95 ± 20.45%) or gait performance (e.g. 66 ± 63.54% in Gross Motor Function Measure-88 items, E and D dimensions). Conclusions The improvements achieved in the short term show the importance of working strength and power functions meanwhile over-ground training with postural control. This research could serve as preliminary support for future clinical implementations in any robotic device. Trial registration The study was carried out with the number R-0032/12 from Local Ethical Committee of the Hospital Infantil Niño Jesús. Public trial registered on March 23, 2017: ISRCTN18254257.
