Abstract
Laparoscopic surgeons are at high risk of experiencing musculoskeletal discomfort, which is considered the result of long-lasting static and awkward body postures. We primarily aimed to evaluate whether passive and active work breaks can reduce ratings of perceived discomfort among laparoscopic surgeons compared with no work breaks. We secondarily aimed to examine potential differences in performance and workload across work break conditions and requested the surgeons evaluate working with passive or active work breaks. Following a balanced, randomized cross-over design, laparoscopic surgeons performed three 90 min laparoscopic simulations without and with 2.5 min passive or active work breaks after 30 min work blocks on separate days. The simulation included the following tasks: a hot wire, peg transfer, pick-and-place, pick-and-tighten, pick-and-thread, and pull-and-stick tasks. Ratings of perceived discomfort (CR10 Borg Scale), performance per subtask, and perceived workload (NASA-TLX) were recorded, and the break interventions were evaluated (self-developed questionnaire). Statistical analyses were performed on the rating of perceived discomfort and a selection of the performance outcomes. Twenty-one participants (9F) were included, with a mean age of 36.6 years (SD 9.7) and an average experience in laparoscopies of 8.5 years (SD 5.6). Ratings of perceived musculoskeletal discomfort slightly increased over time from a mean level of 0.1 to 0.9 but did not statistically significantly differ between conditions (p = 0.439). Performance outcomes of the hot wire and peg transfer tasks did not statistically significantly differ between conditions. The overall evaluation by the participants was slightly in favor regarding the duration and content of active breaks and showed a 65% likelihood of implementing them on their own initiative in ≥90 min-lasting laparoscopic surgeries, compared with passive breaks. Both passive and active breaks did not statistically significantly influence ratings of perceived discomfort or perceived workload in a 90 min simulation of laparoscopic surgery, with an overall low mean level of perceived discomfort of 0.9 (SD 1.4). As work breaks do not lead to performance losses, rest breaks should be tested in real-life situations across a complete working shift, where perceived discomfort may differ from this laboratory situation. However, in this respect, it is crucial to investigate the acceptance and practicality of intraoperative work breaks in feasibility studies in advance of assessing their effectiveness in follow-up longitudinal trials.

Abstract
Surgeons have a high rate of work-related musculoskeletal injuries; an area that has received little attention. These injuries result in surgeons performing less efficiently, needing to take time off work, suffering higher rates of burnout, and may ultimately lead surgeons to retire earlier than planned. Otorhinolaryngologists are at particular risk for work-related musculoskeletal injuries. Beyond the clinician, sustaining such injuries can negatively impact patient safety. Ergonomic interventions have been used effectively to reduce work-related musculoskeletal injuries in other professions, yet not in surgery. With traditional teachings of ideal body postures to avoid injury and manual handling training being re-evaluated, it is important to explore evidence based interventions for reducing work-related musculoskeletal injuries in otorhinolaryngologists. New research encourages us to shift the focus away from the traditional one-size-fits-all approach to ergonomics and toward postural recommendations and education that promote a dynamic, individualized approach to avoiding sustained, static and awkward postures.

Abstract
BACKGROUND Work-related musculoskeletal disorders (WMSDs), also referred to as work-related musculoskeletal injuries (MSKIs), cause surgeons pain and discomfort. Implementing ergonomics in the operating room has helped reduce such symptoms. However, there are still many issues that surgeons face when dealing with medical instruments, especially among female surgeons or surgeons with smaller hands. METHODS The Cochrane methodology for performing a systematic review was utilized to search five databases for pertinent literature based on the study question "Do female surgeons or surgeons with smaller hand size, who use surgical instruments have an increased risk of musculoskeletal disorders and discomfort compared to male or larger handed surgeons?". The literature search strategy was designed around the three conceptual domains of surgeons/surgery, smaller hand size, and instrumentation. We searched PubMed, Embase.com, CINAHL Plus with Full Text (EBSCOhost), Scopus, and Web of Science Core Collection. This exploration identified 2165 research publications, and after specific inclusion and exclusion criteria, 19 studies were included in the systematic review. Risk of bias analysis was conducted to assess the quality of the included studies. After conducting a heterogeneity test, a meta-analysis was not performed due to high heterogeneity. RESULTS Using certain surgical instruments presents challenges in the form of MSKIs for female and smaller-handed surgeons. Studies showed that 77% of females and 73% of surgeons who wear < 6.5 glove size report musculoskeletal issues ranging from difficulty of use to pain. Difficulties using surgical instruments and reported injuries have a greater impact on surgical trainees which might deter interest in surgical fields for future proceduralists. Recommendations for improved ergonomic tool design are suggested by some of the included studies to help tackle the MSKIs that surgeons face when performing operations. CONCLUSIONS The number of female surgeons has increased substantially in the last decade. Hence, there exists an urgent need to address the major challenges they encounter by focusing on this specific aspect of workplace safety and health to mitigate injury. Doing so will yield a productive environment while simultaneously protecting the health and safety of both surgeons and patients. SYSTEMATIC REVIEW REGISTRATION The study protocol was registered on PROSPERO (ID: CRD42022283378).

Abstract
Robotic surgery has revolutionized surgical procedures and has provided many advantages over traditional laparoscopic and open surgeries. Despite the benefits, there are concerns about the physical discomfort and injuries that may be experienced by surgeons during robotic surgeries. This study aimed to identify the most common muscle groups implicated in robotic surgeons' physical pain and discomfort. A questionnaire was created and sent to 1000 robotic surgeons worldwide, with a response rate of 30.9%. The questionnaire consisted of thirty-seven multiple-choice questions, three short answer questions, and one multiple-option question pertaining to the surgeon's workload as well as their level of discomfort while and after performing surgery. The primary endpoint was to identify the most common muscle groups implicated in robotic surgeons' physical pain and discomfort. Secondary endpoints were to highlight any correlation between age group, BMI, hours of operation, workout regimen, and significant pain levels. The results showed that the most common muscle groups implicated in physical pain and discomfort were the neck, shoulders, and back, with many of the surgeons attributing their muscular fatigue and discomfort to the ergonomic design of the surgeon console. Despite the level of surgeon comfort the robotic console provides when compared to other conventional forms of surgery, the findings suggest the need for better ergonomic practices during robotic surgeries to minimize physical discomfort and injuries for surgeons.

Abstract
BACKGROUND Fluid leakage through the glove-protective clothing interface is an area of concern for many health care personnel, including emergency medical service providers, who may wear coveralls to protect themselves from multiple types of hazards. There is currently no established standard test method to specifically evaluate the barrier performance of the glove-protective clothing interface region for any personal protective equipment ensemble. OBJECTIVE This study quantifies the fluid leakage at the coverall and glove interface using single and double gloving. METHODS A robotic arm, which can simulate upper extremity movements of health care personnel, was used to test 5 coverall models and an extended examination glove model in single and double glove conditions. RESULTS The results show that there was a significant difference in fluid leakage amounts between some of the coverall models and the number of glove layers studied. Findings also highlight that there is a high correlation between basis weight and stiffness of the coverall fabrics and the fluid leakage amounts. CONCLUSIONS These results underline that coverall constructed from thin and less stiff fabrics can result in lower fluid leakage levels. Also, there was no significant difference in fluid leakage amounts between single and double gloves when tested with each of the coverall models, with the exception of the coveralls with the highest basis weight and stiffness.

Abstract
BACKGROUND Ergonomic development and awareness are critical to the long-term health and well-being of surgeons. Work-related musculoskeletal disorders affect an overwhelming majority of surgeons, and various operative modalities (open, laparoscopic, and robotic surgery) differentially affect the musculoskeletal system. Previous reviews have addressed various aspects of surgical ergonomic history or methods of ergonomic assessment, but the purpose of this study is to synthesize ergonomic analysis by surgical modality while discussing future directions of the field based on current perioperative interventions. METHODS pubmed was queried for "ergonomics," "work-related musculoskeletal disorders," and "surgery," which returned 124 results. From the 122 English-language papers, a further search was conducted via the articles' sources for relevant literature. RESULTS Ninety-nine sources were ultimately included. Work-related musculoskeletal disorders culminate in detrimental effects ranging from chronic pain and paresthesias to reduced operative time and consideration for early retirement. Underreporting symptoms and a lack of awareness of proper ergonomic principles substantially hinder the widespread utilization of ergonomic techniques in the operating room, reducing the quality of life and career longevity. Therapeutic interventions exist at some institutions but require further research and development for necessary widespread implementation. CONCLUSION Awareness of proper ergonomic principles and the detrimental effects of musculoskeletal disorders is the first step in protecting against this universal problem. Implementing ergonomic practices in the operating room is at a crossroads, and incorporating these principles into everyday life must be a priority for all surgeons.

Abstract
OBJECTIVE Investigate the effect of passive, active or no intra-operative work breaks on static, median and peak muscular activity, muscular fatigue, upper body postures, heart rate, and heart rate variability. BACKGROUND Although laparoscopic surgery is preferred over open surgery for the benefit of the patient, it puts the surgeons at higher risk for developing musculoskeletal disorders especially due to the less dynamic and awkward working posture. The organizational intervention intraoperative work break is a workplace strategy that has previously demonstrated positive effects in small-scale intervention studies. METHODS Twenty-one surgeons were exposed to three 90-min conditions: no breaks, 2.5-min passive (standing rest) or active (targeted stretching and mobilization exercises) breaks after 30-min work blocks. Muscular activity and fatigue of back, shoulder and forearm muscles were assessed by surface electromyography; upper body posture, i.e., spinal curvature, by inclination sensors; and heart rate and variability (HRV) by electrocardiography. Generalized estimating equations were used for statistical analyses. This study (NCT03715816) was conducted from March 2019 to October 2020. RESULTS The HRV-metric SDNN tended to be higher, but not statistically significantly, in the intervention conditions compared to the control condition. No statistically significant effects of both interventions were detected for muscular activity, joint angles or heart rate. CONCLUSION Intraoperative work breaks, whether passive or active, may counteract shoulder muscular fatigue and increase heart rate variability. This tendency may play a role in a reduced risk for developing work-related musculoskeletal disorders and acute physical stress responses.

Abstract
OBJECTIVE Musculoskeletal discomfort is associated with repetitive movements and constrained body positions. The current meta-analysis was performed to determine the global prevalence of musculoskeletal symptoms among gynecologic surgeons who perform laparoscopy. METHODS Sources included Embase, MEDLINE, PubMed, CINAHL, Web of Science Core Collection, Cochrane Central Register of Controlled Clinical Trials, and Google Scholar. Articles published between 1980 and 2022 were considered. Studies that assessed self-reported musculoskeletal symptoms were included. Relevant data were extracted and tabulated. RESULTS Twelve studies met the inclusion criteria. In a pooled sample of 1619 surgeons, the estimated prevalence of musculoskeletal symptoms was 82% (95% confidence interval [CI], 70%-89%; I2 , 92%). Female sex was a risk factor, as identified by a pooled odds ratio of 4.64 (95% CI, 2.63-8.19; I2 , 0%) compared with male surgeons. Among surgeons who reported musculoskeletal symptoms, 30% (95% CI, 14%-52%; I2 , 95%) sought treatment and 3% (95% CI, 2%-6%; I2 , 0%) required work hour modifications. CONCLUSION The current meta-analysis provides preliminary evidence of a high prevalence of musculoskeletal symptoms among gynecologic laparoscopic surgeons. Future research is needed to explore the underlying risk factors and interventional strategies to mitigate this risk.

Abstract
PURPOSE OF REVIEW This paper aims to discuss the various work-related musculoskeletal disorders (WRMDs) among urologists and provide an overview of the latest recommendations to improve awareness of ergonomic principles that can be applied in the operating room, with special consideration of challenges faced during pregnancy. RECENT FINDINGS Urologists suffer from a large burden of WRMDs. The main drivers of pain associated with the various surgical approaches include repetitive movements, static and awkward body positions, and the use of burdensome equipment. Pregnant surgeons are at an even greater risk of WRMDs and face high rates of pregnancy complications. Laparoscopy, endoscopy, robot-assisted surgeries, and open surgeries present unique ergonomic challenges for the practicing urologist. Proper posture and equipment use, optimal operating room setup, intraoperative stretching breaks, and an emphasis on teaching ergonomic principles can reduce the risk of WRMDs. Surgeons are also at increased risk of WRMDs during pregnancy but may continue to operate while taking measures to limit physical exertion and fatigue. Improving awareness of and incorporating ergonomic principles early in a urologist's career may reduce the risk of injury and improve operative performance and longevity.

Abstract
BACKGROUND Standard laparoscopy (SL) is responsible for musculoskeletal disorders in surgeons because of poor ergonomic positions, which could be reduced by robot-assisted laparoscopy (RAL) owing to the surgeons' seated position. One of the aims of the ROBOGYN-1004 study (NCT01247779) was to evaluate surgeons' workloads during real-time procedures of gynecological oncological surgery. METHODS Patients with gynecological cancer eligible for minimally invasive surgery were recruited from 13 French centers between December 2010 and December 2015. Physical workload was evaluated using the Borg scale every hour over the surgery duration and the perception of workload evaluated using NASA-TLX at the end of surgery. RESULTS A total of 369 patients were recruited, of whom 176 underwent RAL and 193 underwent SL (per-protocol analysis). Posture during SL was significantly more challenging for all body parts except the back. There was an increase in discomfort over time (up to 4 h) for the hands and arms, neck, and legs in SL compared with RAL. Perceived physical activity and abilities were rated higher in SL than in RAL (p < 0.01), whereas perceived personal performance was higher in SL (p < 0.01). Perceived physical effort during surgery was lower in RAL than in SL. CONCLUSIONS RAL improves the perception of physical workload. Compared with SL, the perceived effort is lower in RAL regardless of the complexity of the surgery.

Abstract
Laparoscopic surgery (LS) has been shown to provide great benefits to patients compared with open surgery. However, surgeons experience discomfort, low-efficiency, and even musculoskeletal disorders (MSDs) because of the poor ergonomic design of laparoscopic instruments. A methodology for the ergonomic design of laparoscopic dissector handles considering three-dimensional (3D) hand anthropometry and dynamic hand positions was addressed in this research. Two types of hand positions for grasping and stretching were scanned from 21 volunteers using a high-resolution 3D scanner. The 3D anthropometric data were extracted from these 3D hand pose models and used to design an improved handle (IH) that provides additional support for the thumb, a better fit to the purlicue, and a more flexible grasp for the index finger. Thirty subjects were invited to evaluate the IH in terms of muscular effort, goniometric study of motion, and efficiency and effectiveness during four trials of a laparoscopic training task. Questionnaires provided subjective parameters for ergonomic assessment. Positive results included less muscle load in the trapezius as well as significant but small angular differences in the upper limb. No significant reduction in the trial time and no increased percentage of the achievement were observed between the IH and the commercial handle (CH). Improved intuitiveness, comfort, precision, stability, and overall satisfaction were reported. IH provides significant ergonomic advantages in laparoscopic training tasks, demonstrating that the proposed methodology based on 3D anthropometry is a powerful tool for the handle design of laparoscopic dissectors and other surgical instruments.

Abstract
STUDY DESIGN Cross-sectional survey. OBJECTIVES This study aimed to investigate work-related neck pain among AO spine surgeons in different regions by estimating its prevalence, predictors, consequences, and management methods. METHODS A cross-sectional survey of 411 spine surgeon members of AO spine was conducted during March-May 2021, using the Modified Nordic Questionnaire and the Neck Disability Index. Data on neck pain experience during the last 12 months and its consequences and risk factors were collected. Logistic regression analysis was done to identify significant predictors of neck pain. Significance was set at P < .05. RESULTS The 1-year neck pain was experienced by 66.7% of surgeons. According to the Neck Disability Index, more than one-half (52.8%) experienced disability due to neck pain of mild (45.5%), moderate (6.5%), and severe (.8%) grades. Neck pain was responsible for stopping work in 17.5% of surgeons, with a median of 3.5 (IQR, 2-7.8) days off work. One-half of the participants (56.3%) were treated by medical care, 31.5% by physiotherapy, and 16.5% requested rest days and sick leave. Physical stress (P < .001) and non-exercising (P = .04) were the significant predictors of neck pain. CONCLUSION The 12-month prevalence of neck pain was high among spine surgeons, with an impact on activities of daily living, mainly of a mild degree, reported by one-half of surgeons. Physical stress was the only significant predictor, while sports practice was a protective factor against neck pain. Medication was the primary management adopted-an increased focus on pain prevention through improved workplace ergonomics and sports activity programs is recommended.

Abstract
The Senhance Surgical System allows for infrared eye tracking, haptic feedback, and an adjustable upright seat allowing for improved ergonomics. This systematic review was designed with the aim of reviewing the current literature pertaining to the use of the Senhance Surgical System in colorectal surgery. Medline, EMBASE, and CENTRAL were searched. Articles were eligible for inclusion if they evaluated adults undergoing colorectal surgery with the Senhance Surgical System. The primary outcome was intraoperative efficacy; as defined by operative time, estimated blood loss (EBL), and conversion. A DerSimonian and Laird inverse variance random-effects meta-analysis was used to generate overall effect size estimates and narrative review was provided for each outcome. Six observational studies with 223 patients (mean age: 63.7, 41.2% female, mean BMI: 24.4 kg/m2) were included. The most common indication for surgery was colorectal cancer (n = 180, 80.7%) and the most common operation was anterior resection (n = 72, 32.3%). Meta-analyses demonstrated a pooled total operative time of 229.8 min (95% CI 189.3-270.4, I2 = 0%), console time of 141.3 min (95% CI 106.5-176.1, I2 = 0%), and docking time of 10.8 min (95% CI 6.4-15.2, I2 = 0%). The pooled EBL was 37.0 mL (95% CI 24.7-49.2, I2 = 20%). Overall, there were nine (4.0%) conversions to laparoscopy/laparotomy. The Senhance Surgical System has an acceptable safety profile, reasonable docking and console times, low conversion rates, and an affordable case cost across a variety of colorectal surgeries. Further prospective, comparative trials with other robotic surgical platforms are warranted.

Abstract
BACKGROUND Cumulative musculoskeletal stress during operative procedures can contribute to the development of chronic musculoskeletal injury among surgeons. This is a concern in laparoscopic specialties where trainees may incur greater risk by learning poor operative posture or technique early in training. This study conducted an initial investigation of the physical stress encountered during the conduct of foregut laparoscopic surgery. METHODS Subjects were divided into two groups based on their surgical experience level, high experience (HE), consisting of two attending surgeons, and low experience (LE), consisting of two fellow surgeons and a surgical chief resident. Nine distinct foregut laparoscopic procedures were observed for data collection within these groups. Electromyographic (EMG) activity was collected at the bilateral neck, shoulders, biceps, triceps, and lower back for each procedure. Physical workload was measured using percent reference voluntary contractions (%RVC) for each surgeon's muscle activities. Fatigue development was assessed using the median frequency of EMG data between two consecutive cases. Subjects completed a NASA-TLX survey when surgery concluded. RESULTS LE surgeons experienced higher levels of %RVC in the lower back muscles compared to HE surgeons. LE fatigue level was also higher than HE surgeons across most muscle groups. A decrease in median frequency in six of the ten muscle groups after performing two consecutive cases, the largest decrements being in the biceps and triceps indicated fatigue development across consecutive cases for both surgeon groups. CONCLUSION Surgeons developed fatigue in consecutive cases while performing minimally invasive surgery (MIS). HE surgeons demonstrated a lower overall physical workload while also demonstrating different patterns in muscle work. The findings from this study can be used to inform further ergonomic studies and the data from this study can be used to develop surgical training programs focused on the importance of surgeon ergonomics and minimizing occupational injury risk.

Abstract
OBJECTIVE Work-related musculoskeletal disorders are widespread among surgeons, causing significant disability and career modification. Gender plays a role, as female surgeons have a two-fold greater risk for discomfort during certain operations due to generally smaller hand sizes and height as compared to male surgeons. There is a lack of appropriate surgical instrumentation geared toward smaller hand sizes. Maintaining a neutral position while operating, frequent changes in position, and increased awareness can contribute to decreasing the detrimental impact on surgeons' bodies from performing operations.

Abstract
Laparoscopy is a cornerstone of modern surgical care, with clear advantages for the patients. However, it has also been associated with inducing upper body musculoskeletal disorders amongst surgeons due to their propensity to assume non-neutral postures. Further, there is a perception that patients with high body mass indexes (BMI) exacerbate these factors. Therefore, surgeon upper body postures were objectively quantified using inertial measurement units and the LUBA ergonomic framework was used to assess posture during laparoscopic training on patient models that simulated BMIs of 20, 30, 40 and 50 kg/m2. In all surgeons the posture of the upper body significantly worsened during simulated laparoscopic surgery on the BMI 50 kg/m2 model as compared to the baseline BMI model of 20 kg/m2. These findings suggest that performing laparoscopic surgery on patients with high BMIs increases the prevalence of non-neutral posture and may further increase the risk of musculoskeletal disorders in surgeons.

Abstract
PURPOSE Pediatric surgeons are exposed to intense work-related activities, depending on their profession, including residency training. This study aims to investigate the musculoskeletal symptoms and analyze the relationship between musculoskeletal symptoms and the demographics, physical activity levels, and body mass index (BMI) of pediatric surgeons. METHODS A total of 82 pediatric surgeons (female, 20; male, 62) were included in this study. The musculoskeletal symptoms were determined using the Cornell Musculoskeletal Discomfort Questionnaire. The levels of physical activity were determined using the International Physical Activity Questionnaire. RESULTS The mean age of the participants was 48.97 ± 8.894 years, the mean BMI was 26.72 ± 4.12 kg/m2, and the mean working time after acquiring their specialty was 18.65 ± 9.83 years. The average surgery counts per week were 15.22 ± 12.17. Pediatric surgeons mostly complained from lower back pain, upper back pain, neck pain, and right and left shoulder pain. Surgeons with higher BMI had higher pain scores and received more treatment sessions. CONCLUSIONS Pediatric surgeons' complaints are related to their total numbers of surgery. Higher BMI and lower physical activity seem to be the major contributing factors for developing musculoskeletal symptoms. The study results indicated that surgeons should keep their BMI levels to the optimum and increase their physical activity levels.

Abstract
Purpose Laparoscopy is used in many surgical specialties. Subjective reports have suggested that performing laparoscopic surgery in patients with a high body mass index (BMI) is leading to increased prevalence of musculoskeletal symptoms in surgeons. The aim of this study was to objectively quantify the impact on surgeon upper body kinematics and dynamic workload when performing simulated laparoscopy at different BMI levels. Methods Upper body kinematics and dynamic workload of novice, intermediate and expert surgeons were calculated based on measurements from inertial measurement units positioned on upper body segments. Varying thicknesses of foam were used to simulate patient BMIs of 20, 30, 40 and 50 kg/m2 during laparoscopic training. Results Significant increases in the jerkiness, angular speed and cumulative displacement of the head, torso and upper arms were found within all experience groups when subject to the 40 and 50 kg/m2 models. Novice surgeons were found to have less controlled kinematics and larger dynamic workloads compared to the more experienced surgeons. Conclusions Our findings indicate that performing laparoscopic surgery on a high BMI model worsens upper body motion efficiency and efficacy, and increases dynamic workload, producing conditions that are more physically demanding when compared to operating on a 20 kg/m2 model. These findings also suggest that the head, torso, and upper arm segments are especially affected by high BMI models and therefore exposure to patients with high BMIs may increase the risk of musculoskeletal injury when performing laparoscopic surgery.

Abstract
Poor ergonomics in the operating room can have detrimental effects on a surgeon's physical, psychological and economic well-being. This problem is of particular importance to urologists who are trained in nearly all operative approaches (open, laparoscopic, robotic-assisted, microscopic and endoscopic surgery), each with their own ergonomic considerations. The vast majority of urologists have experienced work-related musculoskeletal pain or injury at some point in their career, which can result in leaves of absence, medical and/or surgical treatment, burnout, changes of specialty and even early retirement. Surgical ergonomics in urology has been understudied and underemphasized. In this Review, we characterize the burden of musculoskeletal injury in urologists and focus on various ergonomic considerations relevant to the urology surgeon. Although the strength of evidence remains limited in this space, we highlight several practical recommendations stratified by operative approach that can be incorporated into practice without interrupting workflow whilst minimizing injury to the surgeon. These recommendations might also serve as the foundation for ergonomics training curricula in residency and continuing medical education programmes. With improved awareness of ergonomic principles and the sequelae of injury related to urological surgery, urologists can be more mindful of their operating room environment and identify ways of reducing their own symptoms and risk of injury.

Abstract
BACKGROUND There is a paucity of prospective data related to surgeon ergonomics, which affects career longevity. Robotic surgical systems may mitigate pain and workload. We hypothesized that ergonomic outcomes would vary based on surgeon height and gender, and the relative benefit of robotic surgery would vary based on these demographics. METHODS Surgeons received questionnaires to fill out immediately before and after surgery to enable calculation of pain scores and task load. Surgeons who were ≤ 66 inches tall were considered "short". Univariable and multivariable regression analyses were performed where appropriate using Stata-MP version 14.2 (StataCorp LLC, College Station, TX). RESULTS There were 124 questionnaires given to 20 surgeons; 97 (78%) were returned, and 12 (12%) laparoscopic operations were excluded, leaving 85 (69%) questionnaires for further analysis: 33 (38%) from short surgeons, and 24 (28%) from women, for 30 (35%) robotic and 55 (65%) open operations. There were 44/85 (52%) surgeons who reported worse pain after surgery. Overall pain scores (1.1 ± 2.6 vs 1.5 ± 2.6, p = 0.70) were similar for robotic and open operations. In multivariable analysis, greater surgeon pain scores were significantly associated with short surgeons (p < 0.001), male surgeons (p < 0.001), and long operative times (p = 0.03). Physical demand was lower for robot vs open operations (median 10 vs 13, p = 0.03). When short surgeons (p = 0.04) and male surgeons (p = 0.03) were examined as sub-groups, lower physical demand during robotic operations persisted, but was lost when only examining tall surgeons (p = 0.07) and female surgeons (p = 0.13). CONCLUSIONS Short surgeons and male surgeons reported significantly more pain after both open and robotic operations but had less physical demand when using the robotic system. Future work should focus on mitigation of surgeon height-related factors and seek to understand ergonomic gender differences beyond height.

Abstract
Surgeons have increased physical stress during laparoscopic surgery due to operative site constraints. We developed a wearable device to reduce the physical stress on surgeons' lower extremities. The device mechanically facilitates maintaining a near-upright posture. The surgeon's knees are gently bent by a knee-joint locking mechanism, and fixing and releasing are performed independently on each side. The subjects were one female and two male surgeons, who wore the device during laparoscopic inguinal hernia repair or high anterior resection. Surface electromyogram (EMG) was conducted for both iliopsoas muscles. Control values were determined with the subject not wearing the device. Participants completed a post-procedure questionnaire. With the device, EMG activity had a tendency to decrease in the left iliopsoas muscle (P = .055), but it changed little on the right (P = .406). The post-procedure questionnaire showed an overall positive impression, although subjects reported some difficulty walking. This device decreases EMG activity and may improve a surgeon's work environment.

Abstract
The aim of this systematic review was to summarise the effects of ergonomics interventions on work-related upper limb musculoskeletal pain and dysfunction, and on productivity in sonographers, surgeons and dentists. A total of 31 studies were included. All studies reported effects on upper limb pain. Nine studies reported effects on dysfunction and only two studies reported effects on productivity. Moderately strong evidence in reducing upper limb pain was found for instigation of microbreaks into long duration surgical procedures, and the use of wider, lighter handles in dental instruments. Moderate evidence was also found for use of prismatic glasses and favourable positioning in reducing upper limb pain. Weak, inconsistent or no evidence was found for all other ergonomics interventions in reducing upper limb pain and dysfunction and increasing productivity. The lack of high quality research, particularly in sonographers and in the outcome of productivity, should be addressed.

Abstract
INTRODUCTION Laparoscopy has partially replaced open surgery due to the lower infection rate for the patient and hence better and shorter recovery. However, the surgeon's physical load is higher due to longer duration static and awkward body postures, increasing the risk for developing work-related musculoskeletal disorders. Interventions of an organisational nature are work breaks, being either passive or active. The primary objectives of this study are to determine whether passive and active work breaks lead to less discomfort than no work breaks and whether active work breaks lead to less discomfort than passive work breaks. METHODS AND ANALYSIS A controlled, randomised cross-over trial will be performed in the laboratory, of which its protocol is described here according to the Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) 2013 Statement. Recruitment of 21 laparoscopic surgeons started in April 2019 and the study is ongoing. The participating surgeons will perform three 1.5 hour experimental conditions, one without work breaks, one with 2.5 min passive work breaks including rest, and one with 2.5 min active work breaks including mobility and stretching exercises. The work breaks will be taken after 30 and 60 min of work. During the experiments, outcomes will be recorded. The primary outcome is rating of perceived discomfort measured on an 11-point numeric rating scale. The secondary outcomes are performance, muscle activity of selected muscles, upper body angles, heart rate, workload and subjective evaluation of both interventions. The collected data will be tested using a one-way or two-factorial repeated-measures analysis of variance. ETHICS AND DISSEMINATION Ethical approval of the study protocol was received by the local medical ethical committee of the University of Tübingen in February 2019 (no 618/2018BO2). The results of this study will be presented at national and international conferences, submitted for publications in peer-reviewed journals and serve as the starting point for a feasibility study. TRIAL REGISTRATION NUMBER NCT03715816.

Abstract
Plastic surgeons report the highest prevalence of chronic musculoskeletal pain and fatigue among surgical subspecialties. Musculoskeletal pain impacts daily life, career longevity, and economic burden secondary to occupational injury. Poor postural awareness and ergonomic set up in the operating room represent the most common etiology. Methods A literature review was performed to highlight the ergonomic set-up, postural pitfalls, occupational injuries, and musculoskeletal pain in the operating room. An institutional survey was administered among resident and attending surgeons regarding musculoskeletal pain, posture, ergonomic education, and future improvements. Literature results, survey data, and intraoperative photographs were analyzed in collaboration with physical therapists and personal trainers. Results Survey results demonstrated that 97% of resident and attending respondents experienced musculoskeletal pain and 83% reported a lack of education in posture and ergonomics. The main postural pitfalls included head forward and flexed positioning, abduction and internal arm rotation, and kyphosis of the thoracic spine. The collaborators developed instructional videos to assess posture and biomechanics and demonstrate targeted stretching and strength exercises to address specific neck, back, and shoulder pain. Conclusions Poor posture is unavoidable in the operating room at times. These educational videos should be utilized for self-motivated and prophylactic conditioning outside of the operating room to maintain physical well-being throughout a career in plastic surgery. Future focus should be aimed at implementing dedicated ergonomic education and physical wellness programs early in surgical resident training.

Abstract
BACKGROUND Surgeon workload is significant both mentally and physically and may differ by procedure type. When comparing laparoscopic surgery and open surgery, studies have reported contrasting results on the physical and mental workload assessed. METHODS Wearable posture sensors and pre-/post-surgical questionnaires were employed to assess intraoperative workload and to identify risk factors for surgeons using objective and subjective measures. RESULTS Data from 49 cases (27 open and 22 laparoscopic surgeries performed by 13 male and 11 female surgeons) were assessed. More than half the surgeons reported a clinically relevant post-surgical fatigue score. The surgeons also self-reported a significant increase in pain for the neck, upper back, and lower back during/after surgery. Procedural time had significant impacts on fatigue, body part pain, and subjective (NASA-TLX) workload. The objectively assessed intraoperative work postures using wearable sensors showed a high musculoskeletal risk for neck and lower back based on their posture overall. Open surgeries had significantly larger neck angles (median [IQR]: 40 [28-47]°) compared with laparoscopic surgeries (median [IQR]: 23 [16-29]°), p < 0.001) and torso (median [IQR]: 17 [14-22]° vs. 13 [10-17]°, p = 0.006). CONCLUSION Surgeons reported significantly higher levels of fatigue and pain in the neck and lower back during or after performing a surgical case. Longer procedural time resulted in more self-rated fatigue, pain, and subjective workload. Open surgery had higher postural risk. Overall, surgeons spent a disturbingly high percentage of time during surgery in high-risk musculoskeletal postures, especially the neck. These results show that intraoperative postural risk is very high and that interventions are necessary to protect surgeon musculoskeletal health for optimal surgeon performance and career longevity.

Abstract
BACKGROUND Minimal access surgery has fast become the standard of care for many operative procedures, but is associated with lot of ergonomic stress to the surgeons performing these procedures, which may result in reduction in surgeon's performance and work capacity. In this study, we evaluated the impact of structured training program in improving the ergonomic stress in trainee laparoscopic surgeons. METHODS Laparoscopic surgeons were divided in 2 groups: trainee surgeons (ten) and expert surgeons (three). Baseline surface electromyography (sEMG) data were collected from bilateral deltoid, biceps brachii, forearm extensors, and pronator teres during a predefined suturing task on Tuebingen trainer with integrated porcine organs in both the groups. Trainee surgeons underwent 20 h of laparoscopic intra-corporeal suturing training and surface electromyography data were recorded at the end of training again and compared with baseline. RESULTS Experts were found to have lower muscle activation (p < 0.05) and muscle work (p < 0.05) and better bimanual dexterity than the trainee surgeons at baseline. After training, the trainee surgeons showed significant improvement (p = 0.01), but still did not reach the values of the expert surgeons (p = 0.01). Right deltoid and pronator teres muscles were found to have maximal activity while performing intra-corporeal suturing. CONCLUSION Structured and focused training outside operation theater can significantly reduce unnecessary muscle activation of trainee laparoscopic surgeons and better dexterity leading on to lesser ergonomic stress and thus possibly may reduce the risk of development of future musculo-skeletal disorders.

Abstract
BACKGROUND Musculoskeletal pain is commonly described in surgeons. Research suggests that 21-60% of at-risk physicians may experience significant work-related pain in their back, shoulders, neck or upper extremity and the consequences of this may impact negatively on patient care. Laparoscopic surgery in particular has become increasingly associated with musculoskeletal pain, especially in the cervical spine. Due to a number of constraints, however, it is difficult to evaluate musculoskeletal movement (particularly cervical spine motion) in the operating room environment. STUDY DESIGN Three consultant general surgeons were fitted with an ambulatory strain gauge in an attempt to accurately measure and compare cervical motility during open and laparoscopic surgeries. Intraoperative figures pertaining to neck flexion, extension and rotation during forty surgical procedures were collected. The completed data consisted of twenty open and twenty laparoscopic procedures, and the results were compared. RESULTS There was a statistically significant reduction (21.38%) in measured neck movement in laparoscopic surgery when compared with open surgery p = 0.004 (Table 2). A standard deviation of 18.97 was computed for open surgery indicating a larger variability in results deviation from the mean when compared with a value of 8.92 for laparoscopic surgery. Mean rotational neck movement was also reduced during laparoscopic procedures (23.5%) when compared with open procedures (87.9%). CONCLUSION Based on our results, we believe that laparoscopic surgery requires more prolonged periods of static neck posture when compared with open surgery. This difference may assist in understanding the contributing factors for musculoskeletal (in particular cervical) pain encountered in minimally invasive surgeons. Further investigation of static posture in the operating surgeon is warranted.

Abstract
OBJECTIVE The goal of this work is to determine whether muscular fatigue concurrently reduces cognitive attentional resources in technical tasks for healthy adults. BACKGROUND Muscular fatigue is common in the workplace but often dissociated with cognitive performance. A corpus of literature demonstrates a link between muscular fatigue and cognitive function, but few investigations demonstrate that the instigation of the former degrades the latter in a way that may affect technical task completion. For example, laparoscopic surgery increases muscular fatigue, which may risk attentional capacity reduction and undermine surgical outcomes. METHOD A total of 26 healthy participants completed a dual-task cognitive assessment of attentional resources while concurrently statically fatiguing their shoulder musculature until volitional failure, in a similar loading pattern observed in laparoscopic procedures. Continuous and discrete monitoring task performance was recorded to reflect attentional resources. RESULTS Electromyography of the anterior deltoid and descending trapezius, as well as self-assessment surveys indicated fatigue occurrence; continuous tracking error, tracking velocity, and response time significantly increased with muscular fatigue. CONCLUSION Muscular fatigue concurrently degrades cognitive attentional resources. APPLICATION Complex tasks that rely on muscular and cognitive performance should consider interventions to reduce muscular fatigue to also preserve cognitive performance.

Abstract
BACKGROUND In urology, the health implications of open pelvic surgery (OPS) on the patient have been the subject of numerous studies. However, health effects on the surgeon have not yet been sufficiently considered. The present study investigates the relationship between musculoskeletal disorders in urological surgeons and their activity in OPS. MATERIALS AND METHODS From the point of view of occupational physiology, exemplary operations in OPS were examined using the key indicator method (KIM). In addition, a web-based survey among German clinicians was carried out. From the collected variables, models for the prediction of the endpoints pain and disc herniation (DH) were generated by multivariate logistic regression. RESULTS Risk assessment of the operations with KIM could show that OPS presents a significantly increased physical workload and thus potential physical overstraining. Of the 605 participants in the survey, 35.4% were urologists performing OPS, 32.0% were urologists not performing OPS and 32.6% were gastroenterologists (control groups). Activity in OPS had an odds ratio (OR) of 1.09 (confidence interval [CI]: 0.72-1.66, p = 0.69) for predicting pain, and an OR of 1.14 for prediction of DH CI: 0.66-1.94; p = 0.64). Statistically significant factors influencing the perception of pain were BMI, gender and work ability index (WAI), whereas age and WAI were significant for the occurrence of DH. CONCLUSION Our survey could not show that surgeons practicing OPS have a significantly increased rate of musculoskeletal disorders or, in particular, an increased rate of DH in comparison to the control groups. Nevertheless, the rate of reported complaints among all clinicians surveyed is high, and the random risk assessment of the examplary OPS operations could also demonstrate the risk of physical overstraining. Further considerations should therefore be made as to how reduce the strain on the musculoskeletal system.

Abstract
BACKGROUND Laparoscopy is the gold standard approach in numerous surgical procedures. A new generation of robotized instruments has been developed to compensate for the ergonomic constraints of conventional instruments. The main objective was to compare the learning curves of novices for intracorporeal suturing on a laparoscopy pelvitrainer, using either a robotized needle holder or conventional needle holders. The post-training performances under ergonomically difficult conditions were also analyzed. MATERIALS AND METHODS Fifth-year medical students were randomized in group A using a robotized needle holder (JAIMY; Endocontrol, Grenoble, France) and group B using straight conventional needle holders. They undertook four training sessions (intracorporeal knot-tying task) followed by an evaluation session (intracorporeal knots-tying task, frontal suture, and hexagonal suture). RESULTS Twenty participants were included. The performances of the two groups (n = 10) were not significantly different at baseline. During the training sessions, there was a learning curve with a plateau at the third session for both the groups. At the final evaluation session, there was no significant difference between group A and group B for the intracorporeal knot-tying task (median fundamentals of laparoscopic surgery score: 468 versus 474.5 respectively; P = 0.762). There was a significant difference between group A and group B for the frontal suture (median global score: 15.75 versus 3.75 respectively; P = 0.005) but not for the hexagonal suture (median global score: 18 versus 15 respectively; P = 0.284). CONCLUSIONS Learning curves were equally fast using the robotized needle holder versus conventional instruments and led to equivalent performances. Under ergonomically difficult conditions, the robotized needle holder provided an advantage relative to conventional instruments.

Abstract
Introduction: Musculoskeletal (MSK) manifestations represent a common work-related physical complication that affect surgeons and impacts their life and the healthcare service negatively. Aim: The aim of this study was to determine the prevalence of work related MSK manifestations among surgeons in a tertiary care hospital and to identify the possible associated risk factors. Methods: A Web-based self-administered cross-sectional survey was conducted. This study targeted all surgeons regardless of their nationalities, ages, genders, and marital statuses. The questionnaire assessed the participants’ demographic data as well as musculoskeletal manifestations. Results: Most respondents (80%) suffered from MSK manifestations that were related to performing surgeries. Back and neck areas represented the most affected body parts (71.1% and 59.8%, respectively). A significantly higher percentage of those with musculoskeletal manifestations practiced for 5-10 years (28.9%) (p = 0.006). Conclusion: MSK pain is common among Saudi surgeons in different specialties. More attention should be directed to improving the physical environments in which the surgeons are operating. Moreover, surgeons should be educated about the recommended ergonomic positions that can prevent or decrease their work related MSK manifestations.

Abstract
BACKGROUND Manipulation of the endoscope during minimally invasive surgery is a major source of inconvenience and discomfort. This report elucidates the architecture of a novel one-hand controlled endoscope positioning device and presents a practicability evaluation. METHODS AND MATERIALS Setup time and total surgery time, number and duration of the manipulations, side effects of three-dimensional (3D) imaging, and ergonomic complaints were assessed by three surgeons during cadaveric and in vivo porcine trials. RESULTS Setup was accomplished in an average (SD) of 230 (120) seconds. The manipulation time was 3.87 (1.77) seconds for angular movements and 0.83 (0.24) seconds for zooming, with an average (SD) of 30.5 (16.3) manipulations per procedure. No side effects of 3D imaging or ergonomic complaints were reported. CONCLUSIONS The integration of an active zoom into a passive endoscope holder delivers a convenient synergy between a human and a machine-controlled holding device. It is shown to be safe, simple, and intuitive to use and allows unrestrained autonomic control of the endoscope by the surgeon.

Abstract
INTRODUCTION A Minnesota union identified to researchers at the University of Minnesota a concern relevant to a possible relation between their daily workload and outcome of occupational injuries among a population of janitors. OBJECTIVE To assess if the ergonomic workload is related to injuries among janitors. METHODS Following an initial group discussion among janitors, which identified common and hazardous tasks potentially leading to occupational injuries, a questionnaire was developed, pre-tested, and distributed to the janitors. Questions addressed various exposures, including workload, and comprehensive information regarding injury occurrence over two six-month sequential periods (May 2016-October 2016, November 2016-April 2017). Quantitative ergonomic analyses were performed on a sub-group of janitors (n = 30); these included data collection to identify Borg Perceived Exertion (Borg) and Rapid Entire Body Assessment (REBA) scores. Descriptive, multivariable with bias adjustment analyses were conducted on the resulting data. RESULTS Eight tasks were found to be common for janitors. All average REBA scores for the tasks were identified in the high-risk category. The task of repeatedly emptying small trash cans (<25lb) was significantly related to injuries. Average Borg scores fell between the very light perceived exertion and somewhat difficult perceived exertion categories. Multivariable regression analyses indicated that age-sex-standardized ergonomic workload, measured by task frequencies and REBA or Borg scores, was positively related to injury occurrence. CONCLUSIONS Standardized ergonomic workload was positively related to injury occurrence. This information serves as a basis for further research and potential intervention efforts.

Abstract
Surgeons face hazardous working conditions due to ergonomic deficiencies found throughout the operating room. More than 80% of surgeons have succumbed to a work-related injury or illness as a consequence of sustaining awkward or static positions throughout lengthy operations over a career. While the focus of the procedure is directed to the patient, there is little concurrent regard for proper posture or spinal stability. Even when symptoms of discomfort are experienced, they are often ignored. This results in decreased production and may ultimately threaten surgical careers. Surgeons are often unaware of recommendations or guidelines designed to improve their comfort while operating. Furthermore, there is a significant lack of any formal ergonomic education, especially for minimally invasive procedures. Several modifiable risk factors can be adjusted in the operating room to provide a safer working environment. In addition, strengthening, stability, and exercise programs directed by a trained therapist may be employed to improve the surgeon's musculoskeletal health.

Abstract
PURPOSE OF REVIEW Work-related musculoskeletal disorders (WMSDs) are prevalent among surgeons and result in significant disability. We aimed to review the English-language literature regarding ergonomic risk, prevalence of WMSDs, and unique ergonomic considerations of gynecologic surgery. RECENT FINDINGS Surgeon WMSDs are prevalent, with rates ranging from 66 to 94% for open surgery, 73-100% for conventional laparoscopy, 54-87% for vaginal surgery, and 23-80% for robotic-assisted surgery. Risk factors for injury in open surgery include use of loupes, headlamps, and microscopes. Unique risks in laparoscopic surgery include table and monitor position, long-shafted instruments, and poor instrument handle design. In vaginal surgery, improper table height and twisted trunk position create injury risk. Although robotic surgery offers some advantages in neck and shoulder strain, it remains associated with trunk, wrist, and finger strain. SUMMARY WMSDs are prevalent among surgeons but have received little attention because of under-reporting of injury and logistical constraints of studying surgical ergonomics. Future research must aim to develop objective surgical ergonomics instruments and guidelines and to correlate ergonomics assessments with pain and tissue-level damage in surgeons with WMSDs. Ergonomics training should be developed and implemented in order to protect surgeons from preventable, potentially career-altering injuries.

Abstract
Surgeons work in awkward work postures and have high precision demands - well-known risk factors for musculoskeletal pain. Robotic-assisted laparoscopy is expected to be less demanding compared to conventional laparoscopy; however, studies indicate that robotic-assisted laparoscopy is also associated with poor ergonomics and musculoskeletal pain. The ergonomic condition in the robotic console is partially dependent upon the chair provided, which often is a regular office chair. Our study quantified and compared the muscular load during robotic-assisted laparoscopy using one of two custom built ergonomic chairs and a regular office chair. The results demonstrated no differences that could be considered clinically relevant. Overall, the study showed high levels of static and mean muscular activity, increased perceived physical exertion from pre-to-post surgery, and moderate to high risk for musculoskeletal injuries measured by the Rapid Upper Limb Assessment worksheet. Authors advocate for further investigation in surgeons' ergonomics and physical work demands in robotic surgery.

Abstract
The barrier properties of personal protective equipment are vital to healthcare personnel to protect themselves from possible infectious body fluids. Intraoperative exposure of healthcare personnel to body fluids can be substantial in both inpatient and outpatient settings. The glove-gown interface is known as one of the weakest points of the whole personal protective equipment system. However, there is a lack of scientific research designed to investigate the problem. This paper reports the results of experiments using a new testing methodology developed to quantify fluid leakage through the glove-gown interface while simulating surgical settings in terms of operating room personnel activities, exposure types, exposure durations, and physical stresses applied on the interface. This study represents one of the first efforts investigating the amount of fluid leakage through the glove-gown interface for a number of surgical gown and glove models while considering glove material differences and single vs. double gloving. The test results showed that there is a significant difference in fluid leakage amounts between three gown models and four glove models studied. The results also demonstrated that double gloving significantly reduced the fluid leakage compared to single glove use. The mean fluid leakage was lower in the double synthetic glove configurations (M = 2.76g) compared with all other configurations (3GLV, M = 8.3g; 4GLV, M = 9.49g; 5GLV, M = 3.08g; 6GLV, M = 20.03g; double latex, M = 5.22g). Findings highlighted a significant interaction between glove and gown designs, which suggests that gown and gloves should be designed together as a system to minimize or eliminate the fluid leakage.

Abstract
Background Laparoscopic surgery potentially increases the physical burden to operating theater personnel and can cause physical discomfort. This study aims to evaluate if a robotic camera holder (AutoLap™ system) can improve ergonomics for the surgeon and the camera assistant during laparoscopic procedures. Methods A total of thirty cases were included and randomized (15 AutoLap™, 15 control). Five types of surgery were included: right hemicolectomy, fundoplication, sigmoid resection, rectopexy, and low anterior resection. The posture of the surgeon and assistant was photographed during predefined steps of the procedure. MATLAB was used to calculate angles relevant for the RULA score. The RULA score is a validated method to evaluate body posture, force and repetition of the upper extremities. Two investigators assessed the RULA score independently. Three subjective questionnaires (SMEQ, NASA TLX, and LED) were used to assess mental and physical discomfort. Results No differences in patient characteristics were observed. Sixteen fundoplications, seven right hemicolectomies, five sigmoid resections, one rectopexy, and one low anterior resection were included. The mean RULA score of the surgeon was comparable in both groups, 2.58 (AutoLap™) versus 2.72 (control). The mean RULA score of the assistant was significantly different in both groups, with 2.55 (AutoLap™) versus 3.70 (control) (p = 0.001). The inter-observer variability (ICC) was excellent with 0.93 (surgeon) and 0.97 (assistant). The questionnaires showed a significant difference in physical discomfort for the assistant. The LED and SMEQ score were significantly lower in the robotic group. The NASA TLX demonstrated a significant reduction in scores in all domains when using robotics with the exception of the mental domain. Conclusion Use of the AutoLap™ system shows improvement in ergonomics and posture of the first assistant, and ergonomics of the surgeon are not affected. Furthermore, the subjective work load is significantly reduced by using a robotic camera holder.

Abstract
BACKGROUND Exposure to patients' blood/body fluids could be life-affecting, when providing care to patients with infectious diseases. Although the glove-gown interface is considered one of the weakest points of the protective ensemble system, there is a lack of research, and existing standards do not provide much guidance on strategies to minimize gaps between the gowns and gloves. Currently, there is no known standard test method to evaluate fluid leakage or assess performance improvements with new gowns/gloves. STUDY DESIGN A novel test method with a robotic arm, which has the capability to simulate health care personnel's arm movements during fluid exposure, was developed to determine the leakage at the glove-gown interface. This article explains the test method and investigates the effect of movement, exposure type, exposure duration, procedure duration, and existence of pressure on the amount of leaked fluid at the glove-gown interface. RESULTS Test results suggest that, with the exception of procedure duration, all parameters significantly affected the amount of fluid leaked at the glove-gown interface. Leakage was higher for soaking when compared to spraying, increased as the exposure duration increased, and was greater with the application of pressure. CONCLUSIONS The novel method developed in this study could be used by manufacturers of personal protective equipment to evaluate their products. Standard development organizations could adapt this test method in their specifications, testing standards, and guidelines.

Abstract
OBJECTIVE Work-related musculoskeletal disorders (WMSDs) are prevalent among surgeons and may result in practice modification. We aimed to perform a comprehensive review of the English-language literature regarding ergonomic risk, prevalence of WMSDs, and unique ergonomic considerations by route of surgery. METHODS Multiple searches were performed of PubMed and University library resources to access English-language publications related to surgeon ergonomics. Combinations of keywords were used for each mode of surgery, including the following: "ergonomics," "guidelines," "injury," "operating room," "safety," "surgeon," and "work-related musculoskeletal disorders." Each citation was read in detail, and references were reviewed. RESULTS Surgeon WMSDs are prevalent, with rates ranging from 66% to 94% for open surgery, 73% to 100% for conventional laparoscopy, 54% to 87% for vaginal surgery, and 23% to 80% for robotic-assisted surgery. Risk factors for injury in open surgery include use of loupes, headlamps, and microscopes. Unique risks in laparoscopic surgery include table and monitor position, long-shafted instruments, and poor instrument handle design. In vaginal surgery, improper table height and twisted trunk position create injury risk. Although robotic surgery offers some advantages, it remains associated with trunk, wrist, and finger strain. Surgeon WMSDs often result in disability but are under-reported to institutions. Additionally, existing research tools face limitations in the operating room environment. CONCLUSIONS Work-related musculoskeletal disorders are prevalent among surgeons but have received little attention owing to under-reporting of injury and logistical constraints of studying surgical ergonomics. Future research must aim to develop objective surgical ergonomics instruments and guidelines and to correlate ergonomics assessments with pain and tissue-level damage in surgeons with WMSDs.

Abstract
Minimally invasive surgery has made a profound impact on how urologists approach the challenges in reconstruction of the urinary tract. The advent of laparoscopic approaches to reconstructive urology have demonstrated comparable outcomes to open surgery with improved morbidity. The recent adoption of robotic surgery has seen further advancements such as improved visibility and, freedom of movement, and an easier technical learning curve. With these advantages, more reconstructive urology procedures are being performed robotically. Herein, we review reconstructive urology procedures for which robotics have been applied.

Abstract
PURPOSE With reference to four minimally invasive surgery (MIS) cholecystectomies, the aims were (a) to recognize the factors influencing dominant wrist postures manifested by the surgeon; (b) to detect risk factors involved in maintaining deviated wrist postures; (c) to compare the wrist postures of surgeons while using laparoscopic tools. METHODS Video films were recorded during live surgeries. The films were synchronized with wrist joint angles obtained from wireless electrogoniometers placed on the surgeon's hand. The analysis was conducted for five laparoscopic tools used during all surgical techniques. RESULTS The most common wrist posture was extension. In the case of one laparoscopic tool, the mean values defining extended wrist posture were distinct in all four surgical techniques. For one type of surgical technique, considered the most beneficial for patients, more extreme postures were noticed regarding all laparoscopic tools. We recognized a new factor, apart from the tool's handle design, that influences extreme and deviated wrist postures. It involves three areas of task specification including the type of action, type of motion patterns and motion dynamism. CONCLUSIONS The outcomes proved that the surgical technique which is best for the patient imposes the greatest strain on the surgeon's wrist. .

Abstract
BACKGROUND Musculoskeletal injuries are more common among surgeons than among the general population. However, little is known about these types of injuries among plastic surgeons specifically. The authors' goals were to evaluate the prevalence, nature, causes, and potential solutions of these musculoskeletal injuries among plastic surgeons in three different countries: the United States, Canada, and Norway. METHODS A survey was e-mailed to plastic surgeons in the United States, Canada, and Norway, soliciting their demographics, practice description, history of musculoskeletal issues, potential causes of these symptoms, and proposed suggestions to address these injuries. The prevalence of various musculoskeletal symptoms was calculated, and predictors of these symptoms were evaluated using multivariate logistic regression. RESULTS The survey was sent to 3314 plastic surgeons, with 865 responses (response rate, 26.1 percent); 78.3 percent of plastic surgeons had musculoskeletal symptoms, most commonly in the neck, shoulders, and lower back. U.S. surgeons were significantly more likely to have musculoskeletal symptoms than Norwegian surgeons (79.5 percent versus 69.3 percent; p < 0.05); 6.7 percent of all respondents required surgical intervention for their symptoms. The most common causative factors were long surgery duration, tissue retraction, and prolonged neck flexion. The most common solutions cited were core-strengthening exercises, stretching exercises, and frequent adjustment of table height during surgery. CONCLUSIONS Plastic surgeons are at high risk for work-related musculoskeletal injuries. Ergonomic principles can be applied in the operating room to decrease the incidence and severity of those injuries, and to avoid downstream sequelae, including the need for surgery.

Abstract
Background Many surgeons experience work-related pain and musculoskeletal symptoms; however, comprehensive reporting of surgeon ailments is lacking in the literature. We sought to evaluate surgeons' work-related symptoms, possible causes of these symptoms, and to report outcomes associated with those symptoms. Materials and methods Five major medical indices were queried for articles published between 1980 and 2014. Included articles evaluated musculoskeletal symptoms and ergonomic outcomes in surgeons. A meta-analysis using a fixed-effect model was used to report pooled results. Results Forty articles with 5152 surveyed surgeons were included. Sixty-eight percent of surgeons surveyed reported generalized pain. Site-specific pain included pain in the back (50%), neck (48%), and arm or shoulder (43%). Fatigue was reported by 71% of surgeons, numbness by 37%, and stiffness by 45%. Compared with surgeons performing open surgery, surgeons performing minimally invasive surgery (MIS) were significantly more likely to experience pain in the neck (OR 2.77 [95% CI 1.30–5.93]), arm or shoulder (OR 4.59 [2.19–9.61]), hands (OR 2.99 [1.33–6.71], and legs (OR 12.34 [5.43–28.06]) and experience higher odds of fatigue (8.09 [5.60–11.70]) and numbness (6.82 [1.75–26.65]). Operating exacerbated pain in 61% of surgeons, but only 29% sought treatment for their symptoms. We found no direct association between muscles strained and symptoms. Conclusions Most surgeons report work-related symptoms but are unlikely to seek medical attention. MIS surgeons are significantly more likely to experience musculoskeletal symptoms than surgeons performing open surgery. Symptoms experienced do not necessarily correlate with strain. 68% of surveyed surgeons reported experiencing generalized pain from operating. Minimally-invasive surgeons were more likely to report pain, fatigue, and numbness. Only 29% of surgeons reported seeking treatment for symptoms. No association between objective strain on muscles and reported symptoms was found.

Abstract
INTRODUCTION Minimally invasive surgery (MIS) has shown significant benefits for patients and healthcare systems. However, due to the poor ergonomic adaptation of operating rooms and surgical instruments, most surgeons suffer from pain caused by musculoskeletal disorders (MSDs). METHODS A descriptive survey on MIS surgeons working in different surgical specialties has been carried out in Hospital Valdecilla (Spain). The aim is to determine the prevalence of MSDs using a personal interview and the standardized Nordic questionnaire. The study determines the prevalence of MSDs in different parts of the body and their relationship with epidemiological and labor variables. A questionnaire was filled out by 129 surgeons. RESULTS 90% of surgeons reported MSDs. The higher prevalence appears in the most experienced surgeons. The most affected zones are the lower back (54%), neck (51%), upper back (44%), lower extremities (42%), right shoulder (29%) and right hand (28%). CONCLUSIONS The prevalence of MSDs is higher in MIS surgeons than in any other occupational group. The most vulnerable group is experienced surgeons and there is a potential risk that symptoms will be increased in the future. Muscle strength is revealed as a protective factor against MSDs.

Abstract
Minimally invasive surgery (MIS) offers cosmetic benefits to patients; however, surgeons often experience pain during MIS. We administered an ergonomic questionnaire to 176 Korean laparoscopic gynecological surgeons to determine potential sources of pain during surgery. Logistic regression analysis was used to identify factors that had a significant impact on gynecological surgeons’ pain. Operating table height at the beginning of surgery and during the operation were significantly associated with neck and shoulder discomfort (P <0.001). The ability to control the operating table height was the single factor most significantly associated with neck (P <0.001) and shoulder discomfort (P <0.001). Discomfort of the hand/digits was significantly associated with the trocar site (P = 0.035). The type of electrocautery activation switch and foot pedal were significantly related to surgeons’ foot and leg discomfort (P <0.001). In evaluating the co-occurrence of pain in 4 different sites (neck, shoulder, back, hand/digits), the neck and shoulder were determined to have the highest co-occurrence of pain (Spearman’s ρ = 0.64, P <0.001). These results provide guidance for identifying ergonomic solutions to reduce gynecological laparoscopic surgeons’ pain. Based on our results, we propose the use of an ergonomic surgical step stool to reduce physical pain related to performing laparoscopic operations.

Abstract
STUDY OBJECTIVE To investigate work-related musculoskeletal disorders (WRMSD) in gynaecological minimal access surgery (MAS), including bariatric (plus size) patients DESIGN: Mixed methods (Canadian Task Force classification III). SETTING Teaching hospital in the United Kingdom. MEASUREMENTS Survey, observations (anthropometry, postural analysis), and interviews. RESULTS Work-related musculoskeletal disorders (WRMSDs) were present in 63% of the survey respondents (n = 67). The pilot study (n = 11) identified contributory factors, including workplace layout, equipment design, and preference of port use (relative to patient size). Statistically significant differences for WRMSD-related posture risks were found within groups (average-size mannequin and plus-size mannequin) but not between patient size groups, suggesting that port preference may be driven by surgeon preference (and experience) rather than by patient size. CONCLUSION Some of the challenges identified in this project need new engineering solutions to allow flexibility to support surgeon choice of operating approach (open, laparoscopic or robotic) with a workplace that supports adaptation to the task, the surgeon, and the patient.
