Feasibility and acceptance of a robotic surgery ergonomic training program

Surgeons' muscle load during robotic-assisted laparoscopy performed with a regular office chair and the preferred of two ergonomic chairs: A pilot study

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.

Measurement of Pain in Multiple Sclerosis

life is pain. It is important to determine the features and the measurement of pain. Common types of pain are described in multiple sclerosis. One-dimensional and multi-dimensional pain scales, which are also used in different painful diseases, are used in the measurement of these pain. Scoring and recording in one-dimensional pain scales are easy and a better measurement is achieved in acute pain. However, the disadvantage of these scales is that they do not give detailed information about the nature of the pain. Multidimensional pain scales are used in chronic and complex pain. Multidimensional scales have some disadvantage about application by patients because of complexity. The development of specific scales for the better measurement of pain in multiple sclerosis is important for the effective treatment of pain in patients.

Prevalence of Work-Related Musculoskeletal Disorders Among Surgeons and Interventionalists: A Systematic Review and Meta-analysis

Importance

Physicians in procedural specialties are at high risk for work-related musculoskeletal disorders (MSDs). This has been called "an impending epidemic" in the context of the looming workforce shortage; however, prevalence estimates vary by study.

Objectives

To estimate the prevalence of work-related MSDs among at-risk physicians and to evaluate the scope of preventive efforts.

Data Sources and Study Selection

Systematic search in MEDLINE (Ovid), Embase (Elsevier), Web of Science, PubMed (National Center for Biotechnology Information), and 2 clinical trial registries, without language restriction, for studies reporting on the prevalence and prevention of work-related MSDs among at-risk physicians published until December 2016. The Meta-analysis of Observational Studies in Epidemiology (MOOSE) guidelines for meta-analyses and systematic reviews of observational studies were used. At-risk physicians were defined as surgeons and medical interventionalists. Studies reporting on specific disorders or pain assessed with validated instruments were included.

Data Extraction and Synthesis

Study characteristics; disease prevalence for the neck, shoulder, back, and upper extremity; and measures of resulting disability were recorded. Study estimates were pooled using random-effects meta-analytic models.

Main Outcomes and Measures

Career prevalence of injuries and 12-month prevalence of pain.

Results

Among 21 articles (5828 physicians [mean age, 46.0 years; 78.5% male; 12.8 years in practice; 14.4 hours performing procedures per week]) included in this systematic review and meta-analysis, pooled crude prevalence estimates of the most common work-related MSDs were degenerative cervical spine disease in 17% (457 of 2406 physicians) (95% CI, 12%-25%), rotator cuff pathology in 18% (300 of 1513 physicians) (95% CI, 13%-25%), degenerative lumbar spine disease in 19% (544 of 2449 physicians) (95% CI, 5%-16%), and carpal tunnel syndrome in 9% (256 of 2449 physicians) (95% CI, 5%-16%). From 1997 to 2015, the prevalence of degenerative cervical spine disease and degenerative lumbar spine disease increased by 18.3% and 27%, respectively. Pooled prevalence estimates for pain ranged from 35% to 60% and differed by assessment instrument. Of those with a work-related MSD, 12% (277 of 2319 physicians) (95% CI, 7%-18%) required a leave of absence, practice restriction or modification, or early retirement. Heterogeneity was considerable for all crude analyses (mean I2 = 93.5%) but was lower for sensitivity analyses (mean I2 = 72.3%). Interventions focused on products and behaviors. Twelve at-risk specialties described a gross lack of awareness and an unmet need for ergonomics education.

Conclusions and Relevance

Prevalence estimates of work-related MSDs among at-risk physicians appear to be high. Further research is needed to develop and validate an evidence-based applied ergonomics program aimed at preventing these disorders in this population.

Assessing work-related musculoskeletal symptoms among otolaryngology residents

PURPOSE

Previous studies have suggested that musculoskeletal symptoms are common among practicing otolaryngologists. Early training can be the ideal time to foster knowledge of ergonomics and develop safe work habits, however, little data exists regarding musculoskeletal symptoms in residents. The purpose of this study was to identify and characterize musculoskeletal symptoms in a preliminary sample of otolaryngology residents.

MATERIALS AND METHODS

A cross-sectional survey incorporating the Nordic Musculoskeletal Questionnaire was sent to 30 Otolaryngology-Head and Neck Surgery residencies to examine musculoskeletal symptoms among residents. A two-sample test of proportions was performed to compare symptoms between male and female residents.

RESULTS

In total, 141 respondents (response rate=34.7%) completed the survey. Fifty-five percent of survey respondents were male and 45% were female. Musculoskeletal symptoms were most frequently reported in the neck (82.3%), followed by the lower back (56%), upper back (40.4%), and shoulders (40.4%). The most common symptoms were stiffness in the neck (71.6%), pain in the neck (61.7%), and pain in the lower back (48.2%). In total, 6.4% of residents missed work and 16.3% of residents stopped during an operation at some point due to their symptoms. Most residents (88.3%) believed their musculoskeletal symptoms were attributed to their surgical training. Female residents were significantly more likely to experience neck (p<0.0001) and wrist/hand (p=0.019) discomfort compared to male residents.

CONCLUSIONS

Musculoskeletal symptoms were common among residents, approaching rates similar to those previously identified in practicing otolaryngologists. Increased emphasis on surgical ergonomics is warranted to improve workplace safety and prevent future injury.
