Abstract
Introduction Prolonged standing during surgery is a cause of musculoskeletal disorders in surgeons. Wearable chairs have reportedly reduced musculoskeletal strain effectively when used in industry. However, discomfort and instability issues may remain. This study examines whether using a wearable chair for surgical procedures imposes negative effects, such as mental or physical strain on surgeons prior to its clinical implementation. Methods This prospective cross-over study compared mental strain and subjective sensations in simulated suturing tasks with and without using Archelis®, a wearable chair (Archelis Inc, Yokohama, Japan). Six surgeons participated in the study. Mental strain was examined using heart rate variations calculated during tasks. Four subjective sensations (fatigue, comfort, balance, and workability) after each task and differences in body localized pain pre- and post-task were compared using a 10 centimetres (cm)-visual analog scale (VAS) score questionnaire. Results Results showed no significant differences in mental strain nor subjective sensations with or without the wearable chair. The mean VAS scores for all four subjective sensations with the wearable chair were relatively positive. There was a slight yet insignificant post-task increase in VAS mean scores for body-localized pain in the lower legs. Conclusions Significant negative effects on surgeons from the wearable chair were not observed during simulated suturing procedures. This demonstrates no major barriers in the initial phases of wearable chairs integration into the surgery environment.

Abstract
This document presents the ergonomic assessments carried out by Spanish surgeons on the materials used within an operating room. With the objective of disseminating and raising awareness of the importance of ergonomics, this working group has compiled information from a previously conducted survey on musculoskeletal disorders associated with surgical work from the year 2022, obtaining feedback from 131 surgeons from 17 distinct specialties. A noteworthy 80.2 % of surveyed surgeons reported having experienced forced postures during surgery, and 96.9 % believe that their physical discomfort is a result of the posture adopted during operations. Such postures can result in the development of pathologies and may have a direct impact on work performance and even in extreme cases, it can lead to sick leave or early retirement. By providing their insights on electronic devices, surgical furniture, and instrumentation, surgeons can help identify areas for improvement in the practice of their profession.

Zadeh SM, MacDermid J, Johnson J, Birmingham TB, Shafiee E. Applications of wearable sensors in upper extremity MSK conditions: a scoping review. J Neuroeng Rehabil 2023; 20:158. [PMID: 37980497 PMCID: PMC10656914 DOI: 10.1186/s12984-023-01274-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2023] [Accepted: 10/30/2023] [Indexed: 11/20/2023] Open
Abstract
PURPOSE This scoping review uniquely aims to map the current state of the literature on the applications of wearable sensors in people with or at risk of developing upper extremity musculoskeletal (UE-MSK) conditions, considering that MSK conditions or disorders have the highest rate of prevalence among other types of conditions or disorders that contribute to the need for rehabilitation services. MATERIALS AND METHODS The preferred reporting items for systematic reviews and meta-analysis (PRISMA) extension for scoping reviews guideline was followed in this scoping review. Two independent authors conducted a systematic search of four databases, including PubMed, Embase, Scopus, and IEEEXplore. We included studies that have applied wearable sensors on people with or at risk of developing UE-MSK condition published after 2010. We extracted study designs, aims, number of participants, sensor placement locations, sensor types, and number, and outcome(s) of interest from the included studies. The overall findings of our scoping review are presented in tables and diagrams to map an overview of the existing applications. RESULTS The final review encompassed 80 studies categorized into clinical population (31 studies), workers' population (31 studies), and general wearable design/performance studies (18 studies). Most were observational, with 2 RCTs in workers' studies. Clinical studies focused on UE-MSK conditions like rotator cuff tear and arthritis. Workers' studies involved industrial workers, surgeons, farmers, and at-risk healthy individuals. Wearable sensors were utilized for objective motion assessment, home-based rehabilitation monitoring, daily activity recording, physical risk characterization, and ergonomic assessments. IMU sensors were prevalent in designs (84%), with a minority including sEMG sensors (16%). Assessment applications dominated (80%), while treatment-focused studies constituted 20%. Home-based applicability was noted in 21% of the studies. CONCLUSION Wearable sensor technologies have been increasingly applied to the health care field. These applications include clinical assessments, home-based treatments of MSK disorders, and monitoring of workers' population in non-standardized areas such as work environments. Assessment-focused studies predominate over treatment studies. Additionally, wearable sensor designs predominantly use IMU sensors, with a subset of studies incorporating sEMG and other sensor types in wearable platforms to capture muscle activity and inertial data for the assessment or rehabilitation of MSK conditions.

Ergonomic Assessment of the Surgeon's Physical Workload During Robot-Assisted Versus Standard Laparoscopy in a French Multicenter Randomized Trial (ROBOGYN-1004 Trial). Ann Surg Oncol 2023; 30:916-923. [PMID: 36175710 DOI: 10.1245/s10434-022-12548-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2022] [Accepted: 08/11/2022] [Indexed: 01/06/2023]
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
Work-related musculoskeletal disorders (WMSDs) are common amongst neurosurgeons and can affect a surgeon's ability to operate. Performing surgical ergonomics research is important to minimize the prevalence and effect of WMSDs on the surgeons. The aim of this review is to highlight some of the most important objective and subjective tools available for surgical ergonomics research. Subjective tools can be divided into three categories: (1) questionnaires (either validated or non-validated) filled out by the participants, (2) survey assessments/standardized scoring systems filled out by the researchers, and (3) video analysis. Subjective tools have the drawbacks of recall bias and intra-rater and inter-rater variability. Some of the most important objective tools available are surface electromyography, force plate/pressure sensors analysis, inertial measurement units (IMUs) and kinematics data capturing using reflective markers. Although these modalities do not have the drawbacks that hinder the use of subjective tools, using most of them in the real-life operating theatre, with the exception of IMUs, is challenging. Conducting surgical ergonomics research is important to optimize the performance of neurosurgeons. The advancements towards wearable, wireless technologies will make it easier for surgeons to perform ergonomics research in the operating room.

Abstract
Objectives To investigate the characteristics of neck-shoulder pain (NSP) and explore the potentional relationship between the NSP and the individual and work organizational variables. Methods A cross-sectional study was performed in the tertiary general hospitals in Hunan Province, China between May 2019 and July 2019. A total of 2,030 healthcare workers were enrolled randomly in this study based on a three-stage stratified sampling method. The Neck Disability Index (NDI) was used to measure disability in subjects with neck pain. A self-administered questionnaire was used to assess the characteristics of individual and work organizational variables. The Mann-Whitney U test and the Kruskal-Wallis H test were applied to analyze the prevalence of pain intensity among groups. Multivariate linear regression analysis was performed to explore the potentional relationship between NSP and individual and work organizational variables using the NDI score as the dependent variable. Results 2,008 of 2,030 healthcare workers filled out the survey questionnaires online. In the past 12 months, 1,489 participants (74.2%) complained of pain in the cervical-shoulder region. NDI score increased by 0.10 for each year of age, with healthcare workers working in Obstetrics and Gynecology, and the Operating Room less likely to have NSP than those working in other departments. In contrast, female healthcare workers with a history of pregnancy were more likely to have NSP. In terms of organizational factors, workers who received concern from their supervisor about their health, who had the choice to change their shift status to off duty when they were not feeling well, or who were informed about WMSDs were less likely to have NSP. Conclusion The prevalence of NSP within the previous year was high in this population. Individual factors including history of neck-shoulder diseases, age, and history of pregnancy and organizational factors including being adequately informed regarding WMSDs, concern from supervisors about workers' health, and the ability of workers to change their shift status to off duty when they were not feeling well were shown to induce significant effects to NSP.

Abstract
In the pelvis, anatomic complexity and difficulty in visualization and access make surgery a formidable task. Surgeons are prone to work-related musculoskeletal injuries from the frequently poor design and flow of their work environment. This is exacerbated by the strain of surgery in the pelvis. These injuries can result in alterations to a surgeons practice, inadvertent patient injury, and even early retirement. Human factors examines the relationships between the surgeon, their instruments and their environment. By bridging physiology, psychology, and ergonomics, human factors allows a better understanding of some of the challenges posed by pelvic surgery. The operative approach involved (open, laparoscopic, robotic, or perineal) plays an important role in the relevant human factors. Improved understanding of ergonomics can mitigate these risks to surgeons. Other human factors approaches such as standardization, use of checklists, and employing resiliency efforts can all improve patient safety in the operating theatre.

Abstract
Patient transfer, such as carrying a bedridden patient from a bed to a pedestal pan or a wheelchair and back, is one of the most physically challenging tasks in nursing care facilities. To reduce the intensity of physical labor on nurses or caregivers, a piggyback transfer robot has been developed by imitating the motion when a person holds another person on his/her back. As the chest holder supports most of the weight of the care-receiver during transfer, a human-robot dynamic model was built to analyze the influences of the motion of the chest holder on comfort. Simulations and experiments were conducted, and the results demonstrated that the rotational motion of the chest holder is the key factor affecting comfort. A tactile-based impedance control law was developed to adjust the rotational motion. Subjective evaluations of ten healthy subjects showed that adjusting the rotational motion of the chest holder is a useful way to achieve a comfortable transfer.

Abstract
Background Work-related musculoskeletal disorders (WMSDs) affect a significant percentage of the neurosurgical workforce. The aim of the current questionnaire-based study was to examine the prevalence of WMSDs amongst neurosurgeons, identify risk factors, and study the views of neurosurgeons regarding ergonomics. Methods From June to August 2020, members of the “European Association of Neurosurgical Societies,” the “Neurosurgery Research Listserv,” and the “Latin American Federation of Neurosurgical Societies” were asked to complete an electronic questionnaire on the topics of WMSDs and ergonomics. Results A total of 409 neurosurgeons responded to the survey, with a 4.7 male to female ratio. Most of the surgeons worked in Europe (76.9%) in academic public hospitals. The vast majority of the participants (87.9%) had experienced WMSDs, mainly affecting the shoulder, neck, and back muscles. The most common operations performed by the participants were “Craniotomy for convexity/intrinsic tumors” (24.1%) and “Open lumbar basic spine” (24.1%). Neurosurgeons agreed that ergonomics is an underexposed area in the neurosurgical field (84.8%) and that more resources should be spend (87.3%) and training curricula changes should be made (78.3%) in order to alleviate the burden of WMSDs on neurosurgeons. Univariate analysis did not reveal any associations between the development of WMSDs and age, gender, tenure, average duration of operation, operating time per week, type of operation, and surgical approach. Conclusions The problem of WMSDs ought to be more closely addressed and managed by the neurosurgical community. More studies ought to be designed to investigate specific ergonomic parameters in order to formulate practice recommendations.

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. Practitioner summary: This systematic review investigates the effectiveness of ergonomics interventions on upper limb pain, dysfunction and productivity in sonographers, dentists and surgeons. Instigation of microbreaks during long duration procedures and the use of wider, lighter instrument handles were most effective in reducing upper limb work-related pain.

Abstract
BACKGROUND Female urethral diverticula (UD) are an uncommon and often overlooked aetiology in women presenting with lower urinary tract symptoms, urethral pain, and recurrent urinary tract infection. With increasing awareness, appropriate imaging is more commonly undertaken with consideration given to surgical management. OBJECTIVE The video presented demonstrates the technique for excising large and/or complex UD using a modified prone jack-knife position-a position that offers excellent surgical access and allows the surgeon to operate in a more ergonomic position. DESIGN, SETTING, AND PARTICIPANTS A retrospective review of the data on patients undergoing excision of UD at a tertiary referral unit was performed. SURGICAL PROCEDURE Urethral and suprapubic catheters (±insertion of ureteric stents) were placed in supine position. UD excised in the modified prone jack-knife position (±placement of a Martius flap). MEASUREMENTS Subjective cure rate, recurrence rate, rates of postoperative urinary incontinence, need for secondary incontinence procedure, and postoperative complications were measured. RESULTS AND LIMITATIONS A total of 121 patients were operated on in the study period. The mean follow-up time was 10 mo (range 3-40). The most frequent presenting symptoms included a vaginal mass (n = 76, 63%), followed by dysuria (n = 72, 60%) and pelvic pain (n = 71, 59%). An identifiable aetiological factor was present in 45 patients, including traumatic vaginal delivery (18, 15%), prior periurethral surgery (17, 14%), and urethral dilatation (10, 8%). All patients underwent postvoiding magnetic resonance imaging (MRI) to confirm the diagnosis and plan surgery. UD ranged in maximum diameter from 8 to 48 mm, with a mean of 43 mm (standard deviation 9.24). The most common anatomical location was midurethral (55, 46%), followed by distal (36, 30%), proximal (25, 21%), and full length (5, 4%). Most UDs were single in configuration (74%), followed by multiloculated (15%), saddle shaped (7%), and circumferential (5%). On preoperative videourodynamics, 17 (14%) had stress urinary incontinence. UD excision was undertaken in the modified prone jack-knife position in all cases. A Martius flap was utilised in 36 (30%). The median postoperative postvoiding residual was 26 ml (interquartile range 0-40). In total, 88 (73%) patients were continent postoperatively and 16 (13%) experienced de novo stress urinary incontinence. Of the 37 with pre-existing stress incontinence symptoms, 20 (54%) were continent after operation. A total of 14 patients had subsequent autologous fascial sling at 6 mo. In total, five symptomatic recurrences occurred (4%); of these patients, three elected to undergo surgical excision, all of whom had symptom resolution and were continent after operation. A total of 11 patients (9%) experienced a Clavien-Dindo grade I-II complication within 90 d after operation. Five patients complained of dyspareunia, which resolved by 6 mo. CONCLUSIONS The modified prone jack-knife position facilitates excellent access for excision of both simple and complex UDs. This positioning of the patient is not widely recognised amongst urologists. Using this approach, there were low rates of symptomatic recurrence and de novo stress incontinence at medium-term follow-up. Associated urinary incontinence resolves in over half of patients following UD excision; hence, we advocate deferring any incontinence procedure until after the results of surgery are established. PATIENT SUMMARY Surgical removal of urethral outpouching (diverticula) in women is challenging due to its potential to damage the nearby sphincter muscle, which controls continence, or the urethra tube. Placement of patients on their front, rather than on their back, provides excellent access for the surgical removal of urethral diverticula. With this approach, we achieved excellent rates of cure and low rates of urinary incontinence at an average follow-up of 10 mo.

Integration and Testing of a Three-Axis Accelerometer in a Woven E-Textile Sleeve for Wearable Movement Monitoring. SENSORS 2020; 20:s20185033. [PMID: 32899770 PMCID: PMC7571150 DOI: 10.3390/s20185033] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/06/2020] [Revised: 08/25/2020] [Accepted: 09/03/2020] [Indexed: 12/19/2022]
Abstract
This paper presents a method to integrate and package an accelerometer within a textile to create an electronic textile (e-textile). The smallest commercially available accelerometer sensor (2 mm × 2 mm × 0.95 mm) is used in the e-textile and is fully integrated within the weave structure of the fabric itself, rendering it invisible to the wearer. The e-textile forms the basis of a wearable woven sleeve which is applied to arm and knee joint bending angle measurement. The integrated e-textile based accelerometer sensor system is used to identify activity type, such as walking or running, and count the total number of steps taken. Performance was verified by comparing measurements of specific elbow joint angles over the range of 0° to 180° with those obtained from a commercial bending sensor from Bend Labs and from a custom-built goniometer. The joint bending angles, measured by all three sensors, show good agreement with an error of less than ~1% of reading which provides a high degree of confidence in the e-textile sensor system. Subsequently, knee joint angles were measured experimentally on three subjects with each being tested three times on each of three activities (walking, running and climbing stairs). This allowed the minimum and maximum knee joint angles for each activity to be determined. This data is then used to identify activity type and perform step counting.

J Minim Invasive Gynecol 2020; 28:850-859. [PMID: 32735942 DOI: 10.1016/j.jmig.2020.07.017] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2020] [Revised: 07/15/2020] [Accepted: 07/23/2020] [Indexed: 11/16/2022]
Abstract
STUDY OBJECTIVE The objectives of this study were to (1) pilot a robotic console configuration methodology to optimize ergonomic posture, and (2) determine the effect of this intervention on surgeon posture and musculoskeletal discomfort. DESIGN This was an institutional review board-approved prospective cohort study conducted from February 2017 to October 2017. SETTING A single tertiary care midwestern academic medical center. PARTICIPANTS Six fellowship-trained gynecologic surgeons, proficient in robotic hysterectomy, were recruited: 3 men and 3 women. INTERVENTIONS Each surgeon performed 3 robotic hysterectomies using their self-selected robotic console settings (preintervention). Then, a robotic console ergonomic intervention protocol was implemented by trained ergonomists to improve posture and decrease time in poor ergonomic positions. Each surgeon then performed 3 robotic hysterectomies using the ergonomic intervention settings (postintervention). All surgeries used the da Vinci Xi surgical system (Intuitive Surgical, Inc., Sunnyvale, CA) and were the first case of the day. The surgeons wore inertial measurement unit (IMU) sensors on their head, chest, and bilateral upper arms during surgery. The IMU sensors are equipped with accelerometers, gyroscopes, and magnetometers to give objective measurements of body posture. IMU data were then analyzed to determine the percentage of time spent in ergonomically risky postures as categorized using a modified rapid upper limb assessment. Before and after each hysterectomy, the surgeons completed identical questionnaires for an assessment of musculoskeletal pain/discomfort. The outcome measurements were compared pre- versus postintervention on the basis of fitting generalized linear mixed models that handled the individual surgeon as a random effect and "setting" as a fixed effect. MEASUREMENTS AND MAIN RESULTS With regard to the IMU posture results, there was a significant decrease in time spent in the moderate- to high-risk neck position and a decrease in average neck angle after the ergonomic intervention. The average percentage of time spent in moderate- to high-risk categories was significantly lower for the neck (mean, 54.3% vs 21.0%; p = .008) and right upper arm (mean, 15.5% vs 0.9%; p = .02) when using the intervention settings compared with the surgeons' settings. Pain score results: There were fewer reported increases in neck (4 [22%] vs 1 [6%]) and right shoulder (4 [22%] vs 2 [11%]) pain or discomfort after completion of robotic hysterectomy postintervention versus preintervention; however, these differences did not attain statistical significance (p = .12 and p = .37, respectively). CONCLUSION An ergonomic robotic console intervention demonstrated effectiveness and improved objective surgeon posture at the console when compared with the surgeons' self-selected settings.

Abstract
OBJECTIVE The objective of this study was to estimate the ergonomic postural risk (EPR) for musculoskeletal posture of vascular surgeons performing open and endovascular procedure types and with various adjunctive equipment using wearable inertial measurement unit (IMU) sensors. The hypothesis was that EPR will increase with increased physical and mental demand as well as with procedural complexity. METHODS A prospective, observational study was conducted at a large, quaternary academic hospital located at two sites. Sixteen vascular surgeons (13 male) participated in the study. Participants completed a presurgery and postsurgery survey consisting of a body part discomfort scale and a modified NASA-Task Load Index. Participants wore IMU sensors on the head and upper body to measure EPR during open and endovascular procedures. RESULTS Vascular surgeons have increased EPR scores of the neck as measured by the IMUs and increased lower back pain when performing open surgery compared with non-open surgery (P < .05). Open procedures were rated as more physically demanding. The use of loupes resulted in increased EPR scores for the neck and torso (P < .05), and they were significantly associated with higher levels of lower back pain during procedures (P < .05) as well as with higher levels of physical demand (P < .05). The use of headlights also resulted in increased subjectively measured levels of physical demand and lower back pain. In comparing survey responses with IMU data, surveyed physical demand was strongly and significantly correlated with the neck (r = 0.61; P < .0001) and torso (r = 0.59; P < .0001) EPR scores. The use of lead aprons did not affect EPR or most surveyed measures of workload but resulted in significantly higher levels of distraction (P < .01). The data presented highlight the potential of using wearable sensors to measure the EPR of surgeons during vascular surgical procedures. CONCLUSIONS Vascular surgeons should be aware of EPR during the performance of their duties. Procedure type and surgical adjuncts can alter EPR significantly.

Abstract
BACKGROUND Orthopedic and obstetrician-gynecologist (OB/GYN) surgeons have risks for musculoskeletal disorders (MSD) during work in the operating room (OR). Risks for MSD have not been identified as a result of work outside the OR or during non-work tasks. OBJECTIVE The purpose of the study was to determine risk factors for MSD in an orthopedic and OB/GYN surgeon. METHODS A case study format and mixed method design were used to gather data by using the Rapid Upper Limb Assessment (RULA) to measure MSD risks in the OR; the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) to measure surgeons' upper extremity disability; observation of surgeon office hours; and semi-structured interviews to gather qualitative data. RESULTS Both surgeons had risks for MSD during occupational performance outside of work, with some risks similar to those experienced at work. Both surgeons had MSD risks during work inside and outside the OR. Both surgeons experienced MSD symptoms exacerbated by work and non-work tasks. CONCLUSIONS Identifying and reducing MSD risk should include a comprehensive analysis of occupational performance for orthopedic and OB/GYN surgeons.

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
INTRODUCTION AND HYPOTHESIS We compared musculoskeletal discomfort and postural load among surgeons in sitting and standing positions during vaginal surgery. MATERIALS AND METHODS Assessment of discomfort and posture of the primary surgeons in both positions was performed at two institutions. The primary outcome was an increase in body discomfort score after surgery as determined from subjective responses using validated tools. The secondary outcome was the percentage of time spent in awkward body postures measured objectively and stratified into awkward postures for neck, trunk, and bilateral shoulder angles. Variables were compared between sitting and standing positions using Fisher's exact test for primary outcomes and Wilcoxon rank-sum test for secondary outcomes. RESULTS Data were collected for 24 surgeries from four surgeons in sitting position and nine surgeries from nine surgeons in standing position. The standing surgeons reported a significant increase in discomfort postoperatively for bilateral wrists, thighs, and lower legs compared with the sitting surgeons. The median percentage of time spent in awkward postures was significantly lower for the trunk in the standing versus sitting position (median 0.3% vs 58.8%, p < 0.001) but was significantly higher for both shoulders in the standing versus the sitting position (right shoulder: median 17.8% vs 0.3%, p = 0.003; left shoulder: median 7.4% vs 0.2%, p = 0.003). CONCLUSION Surgeons reported more discomfort in when performing vaginal surgery while standing. The postural load was worse for trunk but favorable for bilateral shoulders when seated. Such differences may impact a surgeon's decision to perform vaginal surgery seated rather than standing.

Abstract
BACKGROUND Work-related pain and discomfort experienced by surgeons is widely reported in the literature. A survey was, therefore, conducted to explore this issue among members of the European Association for Endoscopic Surgery (EAES). METHODS The survey was emailed to 2980 EAES members in 2017 enquiring about their working practice, musculoskeletal (MSK) pain and burnout. RESULTS A total of 569 (19%) surgeons responded, of whom 556 were practicing surgeons; 86% were consultants, 84% were male, and 94% were right-handed. Respondents operated on average 3.3 days/week with 27% of their procedures lasting longer than 3 h. The 386 endoscopists surveyed reported performing an average of 5.3 procedures/day with 83% performing endoscopy at least once per week. Over half of practicing surgeons (62%) reported their worst pain score was 3 or higher (10-point scale) in the past 7 working days, encompassing 71% of their open, 72% laparoscopic, 48% robot-assisted cases and 52% of their endoscopies. Of the 120 surgeons who had ever sought medical help for aches, pain or discomfort, 38% were currently in pain and 16% had considered leaving surgery due to their MSK pain, 26% had reported work-related pain to their employer, 26% had been on short-term disability during their career and 4% long-term disability due to MSK disorders. A significant proportion of the respondents (49%) felt their physical discomfort would influence the ability to perform or assist with surgical procedures in the future. These surgeons reported significantly lower satisfaction from their work (p = 0.024), higher burnout (p = 0.005) and significantly higher callousness toward people (p < 0.001) than those not fearing loss of career longevity. CONCLUSION The results show that MSK pain is prevalent amongst EAES members. Nearly half the respondents had career longevity fears from pain/discomfort which, in turn, correlated with more prevalent feelings of burnout. More emphasis should be placed on the aetiology, prevention and management of musculoskeletal pain in the surgical workforce.

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. Ergonomics training should be developed to protect surgeons from preventable, potentially career-altering injuries.
