An Overview of Robotic Colorectal Surgery Adoption and Training in Brazil. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1675. [PMID: 37763794 PMCID: PMC10535775 DOI: 10.3390/medicina59091675] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/30/2023] [Revised: 09/06/2023] [Accepted: 09/15/2023] [Indexed: 09/29/2023]
Abstract
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.

Robotic Ankle Training Improves Sensorimotor Functions in Children with Cerebral Palsy-A Pilot Study. J Clin Med 2023; 12:jcm12041475. [PMID: 36836010 PMCID: PMC9965715 DOI: 10.3390/jcm12041475] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2022] [Revised: 01/29/2023] [Accepted: 02/10/2023] [Indexed: 02/15/2023] Open
Abstract
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.

Description of the Current Da Vinci ® Training Pathway for Robotic Abdominal Wall Surgery by the European Hernia Society. JOURNAL OF ABDOMINAL WALL SURGERY : JAWS 2022; 1:10914. [PMID: 38314150 PMCID: PMC10831684 DOI: 10.3389/jaws.2022.10914] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/19/2022] [Accepted: 11/14/2022] [Indexed: 02/06/2024]
Abstract
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.

Abstract
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.

Development of a Two-Week Dedicated Robotic Surgery Curriculum for General Surgery Residents. JOURNAL OF SURGICAL EDUCATION 2022; 79:861-866. [PMID: 35351431 DOI: 10.1016/j.jsurg.2022.02.015] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/20/2021] [Revised: 01/24/2022] [Accepted: 02/28/2022] [Indexed: 06/14/2023]
Abstract
BACKGROUND Robotic surgery has seen exponential growth over the past several years. However, there is no standardized training program implemented nationwide. Thus, there is a challenge in how to measure surgical proficiency and how to train future surgeons. METHODS In this study, all PGY3 general surgery residents from the University of Chicago residency program were assigned the curriculum. The curriculum consisted of seven sections: instrument mastery, simulation curriculum, suturing, inanimate drills, laparoscopic/open comparisons, surveys, mentor sessions, and exposure in the operating room. It was administered via a 2-week dedicated robotic rotation. CONCLUSIONS With the inevitable integration of robotic surgery in the operating room, it has become imperative to prepare future surgeons. However, learning curves and a resistance to voluntary compliance have halted progress. Thus, providing mastery-based training and protected time away from clinic duties is paramount. This curriculum aims to reduce these barriers and provide a standardizable training curriculum.

The Effects of Over-Ground Robot-Assisted Gait Training for Children with Ataxic Cerebral Palsy: A Case Report. SENSORS 2021; 21:s21237875. [PMID: 34883877 PMCID: PMC8659941 DOI: 10.3390/s21237875] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/12/2021] [Revised: 11/15/2021] [Accepted: 11/24/2021] [Indexed: 11/17/2022]
Abstract
Poor balance and ataxic gait are major impediments to independent living in ataxic cerebral palsy (CP). Robot assisted-gait training (RAGT) has been shown to improve the postural balance and gait function in children with CP. However, there is no report on the application of RAGT for children with ataxic CP. Here, we report two cases of children with ataxic CP who underwent over-ground RAGT along with conventional therapy for 4 weeks. Outcome measures including the gross motor function measure (GMFM), pediatric balance scale, pediatric reach scale, one-minute walk test, and Timed Up and Go test were assessed before and after the 4-week intervention. Both cases were well adapted to the RAGT system without any significant adverse event. Improvements in the GMFM after RAGT, compared with that in the GMFM, after intensive conventional therapy have been reported previously. It is noteworthy that over-ground RAGT improved areas of the GMFM that did not improve with conventional therapy. In addition, over-ground RAGT with conventional therapy led to improvements in functional balance and walking capacity. These findings suggest that over-ground RAGT is feasible and may be a potential option for enhancing balance and functional walking capacity in children with ataxic CP.

Handlebar Robotic System for Bimanual Motor Control and Learning Research. SENSORS (BASEL, SWITZERLAND) 2021; 21:5991.

Abstract
Robotic devices can be used for motor control and learning research. In this work, we present the construction, modeling and experimental validation of a bimanual robotic device. We tested some hypotheses that may help to better understand the motor learning processes involved in the interlimb coordination function. The system emulates a bicycle handlebar with rotational motion, thus requiring bilateral upper limb control and a coordinated sequence of joint sub-movements. The robotic handlebar is compact and portable and can register in a fast rate both position and forces independently from arms, including prehension forces. An impedance control system was implemented in order to promote a safer environment for human interaction and the system is able to generate force fields, suitable for implementing motor learning paradigms. The novelty of the system is the decoupling of prehension and manipulation forces of each hand, thus paving the way for the investigation of hand dominance function in a bimanual task. Experiments were conducted with ten healthy subjects, kinematic and dynamic variables were measured during a rotational set of movements. Statistical analyses showed that movement velocity decreased with practice along with an increase in reaction time. This suggests an increase of the task planning time. Prehension force decreased with practice. However, an unexpected result was that the dominant hand did not lead the bimanual task, but helped to correct the movement, suggesting different roles for each hand during a cooperative bimanual task.

Abstract
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
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
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
The untethered exoskeletal robot provides patients with the freest and realistic walking experience by assisting them based on their intended movement. However, few previous studies have reported the effect of robot-assisted gait training (RAGT) using wearable exoskeleton in children with cerebral palsy (CP). This pilot study evaluated the effect of overground RAGT using an untethered torque-assisted exoskeletal wearable robot for children with CP. Three children with bilateral spastic CP were recruited. The robot generates assistive torques according to gait phases automatically detected by force sensors: flexion torque during the swing phase and extension torque during the stance phase at hip and knee joints. The overground RAGT was conducted for 17~20 sessions (60 min per session) in each child. The evaluation was performed without wearing a robot before and after the training to measure (1) the motor functions using the gross motor function measure and the pediatric balance scale and (2) the gait performance using instrumented gait analysis, the 6-min walk test, and oxygen consumption measurement. All three participants showed improvement in gross motor function measure after training. Spatiotemporal parameters of gait analysis improved in participant P1 (9-year-old girl, GMFCS II) and participant P2 (13-year-old boy, GMFCS III). In addition, they walked faster and farther with lower oxygen consumption during the 6-min walk test after the training. Although participant P3 (16-year-old girl, GMFCS IV) needed the continuous help of a therapist for stepping at baseline, she was able to walk with the platform walker independently after the training. Overground RAGT using a torque-assisted exoskeletal wearable robot seems to be promising for improving gross motor function, walking speed, gait endurance, and gait efficiency in children with CP. In addition, it was safe and feasible even for children with severe motor impairment (GMFCS IV).

Abstract
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
INTRODUCTION The learning curve associated with robotic pancreatoduodenectomy (RPD) is a hurdle for new programs to achieve optimal results. Since early analysis, robotic training has recently expanded, and the RPD approach has been refined. The purpose of this study is to examine RPD outcomes for surgeons who implemented a new program after receiving formal RPD training to determine if such training reduces the learning curve. METHODS Outcomes for consecutive patients undergoing RPD at a single tertiary institution were compared to optimal RPD benchmarks from a previously reported learning curve analysis. Two surgical oncologists with formal RPD training performed all operations with one surgeon as bedside assistant and the other at the console. RESULTS Forty consecutive RPD operations were evaluated. Mean operative time was 354 ± 54 min, and blood loss was 300 ml. Length of stay was 7 days. Three patients (7.5%) underwent conversion to open. Pancreatic fistula affected five patients (12.5%). Operative time was stable over the study and lower than the reported benchmark. These RPD operative outcomes were similar to reported surgeon outcomes after the learning curve. CONCLUSION This study suggests formal robotic training facilitates safe and efficient adoption of RPD for new programs, reducing or eliminating the learning curve.

Abstract
RATIONALE Myotonic dystrophy type 1 (DM1) is a slowly progressive multisystem neuromuscular disease characterized by myotonia and muscle weakness and wasting of distal and axial muscles. People with DM1, due to the disease progression, are often concerned about their ability to carry out and participate in the activities of daily living. Rehabilitation approaches in DM1, including moderate-to-intense strength training, have shown not univocal efficacy to face such difficulties. Aim of this case-study was to demonstrate the effects of a combined approach by using conventional plus robotic training in rare neuromuscular diseases, such as DM1. PATIENT CONCERNS A 46-year-old woman came to our observation complaining of difficulty in opening fist after strong voluntary muscle contraction for about 20 years. Over the years, she referred swallowing difficulties for solid foods, balance impairment complicated by tendency to stumble and falls, fatigability, hand muscle weakness with difficulty to open bottles and lifting weights, and daytime sleepiness DIAGNOSIS:: Paraparesis in DM1. INTERVENTIONS The patient underwent 2 different trainings. The first period of treatment was carried out by using conventional physiotherapy, 6 times a week (twice a day) for 4 weeks. Then, she underwent a two-month specific task-oriented robotic rehabilitation training for the gait impairment using an overground exoskeleton, namely Ekso-GT, combined to the conventional therapy. OUTCOMES The patient, after the EKSO training, gained a significant improvement in walking, balance and lower limbs muscle strength, as per 10-meter walking test and Left Lower Limb Motricity Index. Neurophysiological data (electroencephalography and surface electromyography) were also collected to more objectively assess the functional outcomes. LESSONS Rehabilitation approaches in DM1, including moderate-to-intense strength training, have shown not univocal efficacy. Emerging and advancing robotic technologies can enhance clinical therapeutic outcomes by allowing therapists to activate and/or modulate neural networks to maximize motor and functional recovery.

Abstract
The best way to teach robotic thoracic surgery is still being decided. New trainees, experienced video-assisted thoracoscopic surgery (VATS) surgeons, and predominantly open surgeons each have different needs when it comes to learning robotic surgery. The data shows that the learning curve and ability to learn robotics initially appears to be shorter and easier than surgeons learning VATS. Though the absolute best method for teaching is still under investigation, multiple centers have started to create systematic methods of teaching robotic surgery that increases resident autonomy while still protecting the patient.

Abstract
OBJECTIVES To investigate operators' performance quality, mental stress, and ergonomic habits through a training curriculum on robotic simulators. DESIGN Forty volunteers without robotic surgery experience were recruited to practice 2 exercises on a dV-Trainer (dVT) for 14 hours. The simulator software (M-scorea) provided an automatic evaluation of the overall score for the surgeons' performance. Each participant provided a subjective difficulty score (validity to be proven) for each exercise. Their ergonomic habits were evaluated based on the workspace range and armrest load-validated criteria for evaluating the proficiency of using the armrest. They then repeated the same tasks on a da Vinci Surgical Skill Simulator for a final-level test. Their final scores were compared with their initial scores and the scores of 5 experts on the da Vinci Surgical Skill Simulator. RESULTS A total of 14 hours of training on the dVT significantly improved the surgeons' performance scores to the expert level with a significantly reduced workload, but their ergonomic score was still far from the expert level. CONCLUSION Sufficient training on the dVT improves novices' performance, reduces psychological stress, and inculcates better ergonomic habits. Among the evaluated criteria, novices had the most difficulty in achieving expert levels of ergonomic skills. The training benefits of robotic surgery simulators should be determined with quantified variables. The detection of the limitations during robotic training curricula could guide the targeted training and improve the training effect.

[PMID: 27488814 DOI: 10.1016/j.jsurg.2016.06.006] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/10/2016] [Revised: 05/11/2016] [Accepted: 06/07/2016] [Indexed: 06/06/2023]
Abstract
OBJECTIVE To investigate whether propagation of robotic technology into urologic practice and training programs has improved baseline urology resident trainee robotic skills. DESIGN Questionnaires were completed by each urology resident trainee participating in a training course and asked about access to robotic simulation, robot experience, and console time. Baseline resident trainee scores on the Mimic Robotic Simulator (Mimic Technologies, Inc., Seattle, WA) from 27 participants of 2012 course were compared with the 2015 scores of 34 trainees on 4 standard Mimic exercises using Wilcoxon rank-sum tests. p = 0.05 or less were considered statistically significant. PARTICIPANTS AND SETTING Totally, 34 resident trainees from 17 programs in the Southeast Section of the American Urological Association participated in an annual 2-day robotic training course. RESULTS Overall score, economy of motion score, and time to complete exercise were all significantly better in the 2015 trainee group compared with the 2012 trainee group (p < 0.001) for the Peg Board 1, Camera Targeting 2, and Energy Dissection exercises. Overall scores for needle targeting improved between 2012 and 2015 (p = 0.04). Trainee access to a simulator was not associated with overall score on any of the 4 exercises in the 2015 group. In the 2015 group, actual robotic console time was associated with better overall scores in Camera Targeting 2 (p = 0.02) and Peg Board 1 (p = 0.04). CONCLUSIONS Baseline resident trainee performance on basic robotic simulator exercises has improved over the past 3 years irrespective of robotic simulator access or console time.

Abstract
BACKGROUND Robotic training is commonly used to assist walking training in patients affected by multiple sclerosis (MS) with non-conclusive results. OBJECTIVE To compare the effect of robot-assisted gait training (RAGT) with that of conventional walking training (CWT) on gait competencies, global ability, fatigue and spasticity in a group of severely affected patients with MS. METHODS A pilot, single-blind randomized controlled trial was conducted in 43 severe (Expanded Disability Status Scale (EDSS) score of 6-7.5) and non-autonomous ambulant in-patients with MS. Experimental group performed 12 sessions of RAGT, whereas control group performed the same amount of CWT. Primary outcome measures were gait ability assessed by 2 minutes walking test and Functional Ambulatory Category; secondary outcomes were global ability (modified Barthel Index), global mobility (Rivermead Mobility Index), severity of disease (EDSS) and subjectively perceived fatigue (Fatigue Severity Scale). RESULTS The number of subjects who achieved a clinical significant improvement was significantly higher in RAGT than in CWT ( p < 0.05 for both primary outcome measures). RAGT also led to an improvement in all the other clinical parameters (global ability: p < 0.001, global mobility: p < 0.001, EDSS: p = 0.014 and fatigue: p = 0.001). CONCLUSIONS RAGT improved the walking competencies in non-autonomous ambulant patients with MS, with benefits in terms of perceived fatigue.

Conventional Laparoscopic vs Robotic Training: Which is Better for Naive Users? A Randomized Prospective Crossover Study. JOURNAL OF SURGICAL EDUCATION 2015; 72:592-599. [PMID: 25687957 DOI: 10.1016/j.jsurg.2014.12.008] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/17/2014] [Revised: 11/18/2014] [Accepted: 12/16/2014] [Indexed: 06/04/2023]
Abstract
OBJECTIVE Robotic training (RT) using the da Vinci skills simulator and conventional training (CT) using a laparoscopic "training box" are both used to augment operative skills in minimally invasive surgery. The current study tests the hypothesis that skill acquisition is more rapid using RT than using CT among naive learners. DESIGN AND PARTICIPANTS A total of 40 subjects without laparoscopic or robotic surgical experience were enrolled and randomized to begin with either RT or CT. Then, 2 specific RT tasks were reproduced for CT and repeated 5 times each with RT and CT. Time and quality indicators were measured quantitatively. A crossover technique was used to control for in-study experience bias. RESULTS The tasks "pick and place jacks" (PP) and "thread the rings" (TR) were achieved faster with RT than with CT despite crossover (p < 0.0001). An RT-favoring difference was observed in speed for both tasks when changing modality. Percentage improvement with increasing trials was similar for RT and CT: RT completion time averaged 39 seconds and 211 seconds (PP and TR, respectively), compared with 65 seconds and 362 seconds when using CT (p < 0.0001); final improvement averaged 26% and 46% for RT (PP and TR, respectively) vs 31% and 47% for CT (p was 0.76 for PP and 0.20 for TR). Within the PP task, RT times averaged 41 seconds without previous CT experience vs 35 seconds with previous CT experience (p = 0.20); CT times averaged 61 seconds without and 69 seconds with previous RT experience (p = 0.48). Comparable times for the TR task were 212 seconds vs 216 seconds (p = 0.66) and 388 seconds vs 334 seconds (p = 0.17). Both instrument collisions and excessive force occurred more commonly for RT than for CT within the TR task (p < 0.0001). CONCLUSIONS Speeds were faster overall with RT than with CT, but the percentage of speed improvement with trials was similar, suggesting similar learning curves, with minimal transfer effect appreciated.

Effects of robotically modulating kinematic variability on motor skill learning and motivation. J Neurophysiol 2015; 113:2682-91. [PMID: 25673732 DOI: 10.1152/jn.00163.2014] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2014] [Accepted: 02/09/2015] [Indexed: 11/22/2022] Open
Abstract
It is unclear how the variability of kinematic errors experienced during motor training affects skill retention and motivation. We used force fields produced by a haptic robot to modulate the kinematic errors of 30 healthy adults during a period of practice in a virtual simulation of golf putting. On day 1, participants became relatively skilled at putting to a near and far target by first practicing without force fields. On day 2, they warmed up at the task without force fields, then practiced with force fields that either reduced or augmented their kinematic errors and were finally assessed without the force fields active. On day 3, they returned for a long-term assessment, again without force fields. A control group practiced without force fields. We quantified motor skill as the variability in impact velocity at which participants putted the ball. We quantified motivation using a self-reported, standardized scale. Only individuals who were initially less skilled benefited from training; for these people, practicing with reduced kinematic variability improved skill more than practicing in the control condition. This reduced kinematic variability also improved self-reports of competence and satisfaction. Practice with increased kinematic variability worsened these self-reports as well as enjoyment. These negative motivational effects persisted on day 3 in a way that was uncorrelated with actual skill. In summary, robotically reducing kinematic errors in a golf putting training session improved putting skill more for less skilled putters. Robotically increasing kinematic errors had no performance effect, but decreased motivation in a persistent way.

Abstract
We seek to provide a background of the current state of pediatric urologic surgery including a brief history, procedural outcomes, cost considerations, future directions, and the state of robotic surgery in India. Pediatric robotic urology has been shown to be safe and effective in cases ranging from pyeloplasty to bladder augmentation with continent urinary diversion. Complication rates are in line with other methods of performing the same procedures. The cost of robotic surgery continues to decrease, but setting up pediatric robotic urology programs can be costly in terms of both monetary investment and the training of robotic surgeons. The future directions of robot surgery include instrument and system refinements, augmented reality and haptics, and telesurgery. Given the large number of children in India, there is huge potential for growth of pediatric robotic urology in India. Pediatric robotic urologic surgery has been established as safe and effective, and it will be an important tool in the future of pediatric urologic surgery worldwide.

Assessment of virtual reality robotic simulation performance by urology resident trainees. JOURNAL OF SURGICAL EDUCATION 2014; 71:302-308. [PMID: 24797844 DOI: 10.1016/j.jsurg.2013.09.009] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/26/2013] [Accepted: 09/05/2013] [Indexed: 06/03/2023]
Abstract
OBJECTIVES To examine resident performance on the Mimic dV-Trainer (MdVT; Mimic Technologies, Inc., Seattle, WA) for correlation with resident trainee level (postgraduate year [PGY]), console experience (CE), and simulator exposure in their training program to assess for internal bias with the simulator. DESIGN Residents from programs of the Southeastern Section of the American Urologic Association participated. Each resident was scored on 4 simulator tasks (peg board, camera targeting, energy dissection [ED], and needle targeting) with 3 different outcomes (final score, economy of motion score, and time to complete exercise) measured for each task. These scores were evaluated for association with PGY, CE, and simulator exposure. SETTING Robotic skills training laboratory. PARTICIPANTS A total of 27 residents from 14 programs of the Southeastern Section of the American Urologic Association participated. RESULTS Time to complete the ED exercise was significantly shorter for residents who had logged live robotic console compared with those who had not (p = 0.003). There were no other associations with live robotic console time that approached significance (all p ≥ 0.21). The only measure that was significantly associated with PGY was time to complete ED exercise (p = 0.009). No associations with previous utilization of a robotic simulator in the resident's home training program were statistically significant. CONCLUSIONS The ED exercise on the MdVT is most associated with CE and PGY compared with other exercises. Exposure of trainees to the MdVT in training programs does not appear to alter performance scores compared with trainees who do not have the simulator.

Assessment of robotic simulation by trainees in residency programs of the Southeastern Section of the American Urologic Association. JOURNAL OF SURGICAL EDUCATION 2013; 70:571-577. [PMID: 24016366 DOI: 10.1016/j.jsurg.2013.04.014] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/27/2013] [Revised: 04/17/2013] [Accepted: 04/28/2013] [Indexed: 06/02/2023]
Abstract
OBJECTIVES To assess the Southeast Section of the American Urological Association (SESAUA) trainee exposure to and thoughts on robotic simulation. DESIGN Questionnaire-based study of SESAUA residency trainees to determine their access to robotic simulation, live robotic experience to date, and opinion regarding the adequacy of current robotic training. SETTING Three trainees from each SESAUA training program were invited to Orlando, Florida for a formal 2-day robotic training course. Day 1 was a 3-component didactic session. Day 2 involved faculty directing the trainees in set tasks on a live porcine model for 4 hours and another 4 hours on the Mimic dV-Trainer (Mimic Technologies, Inc, Seattle, WA) for directed exercises. PARTICIPANTS Thirty-two trainees from 14 programs in the SESAUA participated in the course and filled out a 1-page, 8-item questionnaire following their simulator exposure. RESULTS Seventeen (53.1%) trainees, including 5 urology year-3 trainees, reported never having had robotic console time. Of the trainees, 65.6% (21 of 32) had access to the Mimic dV-Trainer or Mimic "backpack" whereas 10 had no exposure to robotic simulation; 84.4% (27 of 32) felt that the simulator replicated real-life robotic console surgery and 90.6% (29 of 32) felt the simulator was helpful or would be helpful for training in their program. Trainees felt the "tubes 2" drill, which mimics a vesicourethral anastomosis, was the most difficult drill to perform. CONCLUSIONS A majority of trainees in the SESAUA have had limited to no robotic console time. A high number of resident trainees in the SESAUA have exposure to virtual reality robotic simulation. Trainees believe that the simulator replicates real-life robotic console movements and almost all believe they would be benefit from having access to robotic simulation.
