Musculoskeletal Discomfort and Musculoskeletal Injuries in Firefighters of the City of Cape Town Fire and Rescue Service

Objective The prevalence of work-related musculoskeletal injuries is reported to be noticeably high amongst firefighters, which augments the dangers of the job and the difficulties that firefighters must face daily. Therefore, this study aimed to firstly determine the prevalence and characteristics of work-related musculoskeletal injuries (MSIs) and musculoskeletal discomfort (MSD) and, secondly, to determine the relationship between MSD and MSIs in firefighters. Methods Using random systematic sampling, 309 firefighters from the City of Cape Town Fire and Rescue Service were recruited to participate. A researcher-generated questionnaire was used to retrieve data on musculoskeletal injuries and musculoskeletal discomfort. Data was analysed using the T-tests, Cochran-Armitage trend test, Jonckheere-Terpstra test, and Binary logistic regression. A p-value of less than 0.05 was used to indicate statistical significance. Results Male (p = 0.036) and older firefighters (p<0.001) with more years of experience (p = 0.002) were most likely to report a musculoskeletal injury. Falls, jumps, slips, and trips were the most common injuries (39.7%), which most often occurred on the fireground (41.1%). Most firefighters (73.3%) reported experiencing discomfort 1-2 times a week of moderate (60.1%) severity that interfered slightly with their ability to work (58.2%). Multivariable analysis showed that the age groups of 40-49 years and 50-65 years and the rank of station commander increased the risk for MSIs by a factor of 2.39, 2.67, and 3.83, respectively. In addition, MSD was associated with an increase in the likelihood of firefighters reporting MSIs (p <0.001). Conclusion Older male firefighters with more years in service were most likely to experience MSIs. Regular physical activity and work-related training should be implemented to increase the fitness for duty and to reduce the prevalence of injuries in firefighters.

Assessment and evaluation of work-related musculoskeletal disorders among nuclear medicine professionals in India: A cross-sectional study.

Musculoskeletal disorders (MSDs) are a severe occupational health issue among medical radiation practitioners. It is mostly linked to personal protective wear, working posture, tools employed and ergonomics. To assess and evaluate the musculoskeletal disorders among nuclear medicine professionals (NMP) in India. An online survey was distributed to 455 NMP throughout India between November 2021 and March 2022 covering the demographic characteristics and questions for evaluation of musculoskeletal symptoms using the Standardized Nordic Musculoskeletal Questionnaire (NMQ). Participants with any pre-existing musculoskeletal disorder or trauma were excluded. Descriptive statistics summarized the data from the demographics, discomfort, aches and work-related musculoskeletal injuries. Chi-square test was used to examine the association between the obtained values. 91 out of 124 respondents were included based on the inclusion and exclusion criteria. Results shows that there is a significant association between the height of the individual and neck pain, body mass index and elbows pain, age and low back pain, experience in the current work and upper back pain, the weight of the individual and knee pain, use of mobile lead screens and shoulder pain, use of gonad shield, trouble in the ankles and use of lead screens, and QC phantoms for gamma camera / PET and wrists/hands pain. Work-related musculoskeletal disorders among NMP are resulting from factors of individual demographic variables (such as age, height, weight, body mass index), years of experience at the current workplace and of using instruments in their work area.

Robotic assisted surgery reduces ergonomic risk during minimally invasive colorectal resection: the VOLCANO randomised controlled trial

PurposeMinimally invasive surgery benefits patients but poor operating ergonomics causes musculoskeletal injuries in surgeons. This randomised controlled trial aims to assess whether robotic-assisted surgery with the open-console Versius® system can reduce surgeons’ ergonomic risks during major colorectal resections.MethodsProspectively registered at ClinicalTrials.gov (NCT05262296) in March 2022. Adult patients requiring a minimally invasive colorectal resection were potentially eligible. Photographs taken at 2-min intervals were analysed using the objective Rapid Entire Body Assessment (REBA) posture analysis scale to calculate intraoperative surgeon ergonomic risk. Secondary outcomes included team communication (Oxford NOTECHS II), surgeon cognitive strain (modified NASA-TLX scale), and clinical outcomes.ResultsSixty patients were randomised in a 2:1 ratio (40 robot, 20 laparoscopic). Mean age was 65yrs and 34 (57%) were male. Body Mass Index did not differ between the 2 groups (overall mean 29.0 ± 5) and there were equal proportions of left and right-colonic resections.REBA was significantly lower in the robotic arm (median robot REBA score 3 vs lap REBA 5 [p < 0.001]), equating to an injury risk category drop from “medium” to “low risk”. There were no significant differences in team communication, operative duration, or patient outcomes. Surgeon cognitive strain was lower in robotic cases (mean robot 32.4 ± 10.3 vs lap 45.6 ± 14.3 [p < 0.001]).ConclusionsThis trial demonstrates that robotic surgery with an open-console system reduces ergonomic risk scores and cognitive strain during colorectal resections, with no apparent detriment to team communication. This may therefore be a safe & feasible solution to the increasing problem of work-related musculoskeletal injuries in surgeons.

Work-Related Musculoskeletal Injury Rates, Risk Factors, and Ergonomics in Different Endoscopic Specialties: A Review.

Endoscopy-related musculoskeletal injuries (ERIs) are frequent among gastrointestinal, pulmonary, nasal, and urologic endoscopists, impacting the healthcare system. The present review aims to compare the ERI rates, risk factors, and ergonomic recommendations in the different endoscopic fields. A review was conducted using PubMed and Cochrane Library for articles based on surveys and published until 10 January 2024. Demographic, work, and ERI data from 46 publications were included, covering 10,539 responders. The ERI incidence ranged between 14% and 97%, highlighting the need of intervention independent of the specialties. The neck, back, and shoulder were the most frequent ERI locations, while gender, age, years of experience, and procedure volume the most common risk factors. Ergonomic recommendations suggest concentrating on endoscope design changes, especially in gastrointestinal endoscopy, to increase the comfort, adaptability of the equipment in the operating room, and workflow/institutional policy changes. The inclusion of an ergonomic timeout guarantees the correct equipment positioning, the neutralisation of the endoscopist's posture, and an indirect break between procedures. Ergonomic training to increase awareness and best practice should be promoted, also using new technologies. Future research should concentrate on intervention and comparative studies to evaluate to which extent prevention measures and newly designed equipment could reduce ERI incidence.

Prevalence of disability secondary to work-related musculoskeletal injuries among orthopaedic surgeons

BackgroundOrthopaedic surgeons encounter many work-place hazards that can lead to musculoskeletal injuries (MSI) and their clinical sequelae. This study aims to evaluate musculoskeletal injuries among orthopaedic surgeons and compare their rates of disability claims and time off work. Additionally, this study provides a perspective on the financial impact of work-related injuries among orthopaedic surgeons. MethodsAn electronic survey was developed to assess work-place hazards among orthopaedic surgeons. The survey included questions on demographics, musculoskeletal injuries, and disabilities. Electronic surveys were emailed to all current members of the American Academy of Orthopaedic Surgeons (AAOS) between March and April 2021 in the United States. Descriptive statistics were run for all variables and chi-squared and t-tests when applicable. Results1645 members of the AAOS completed the survey (7.03 % response rate), and 243 (14.9 %) reported a work-related injury to their place of employment at some point during their career. Of the respondents, 1129 (76.4 %) reported having active disability insurance, and 61 (3.7 %) orthopaedic surgeons filed a disability claim secondary to a work-related injury at some point during their career. Of the surgeons that claimed disability, 39 (66.1 %) returned to work, and 20 (33.9 %) had an early retirement. Foot/ankle injuries led to the highest rates of early retirement overall (62.5 %). ConclusionThis study captures the prevalence of disability claims made by orthopaedic surgeons due to work-place hazards. To our knowledge, this is the first study to broadly compare disability claims amongst orthopaedic surgeons. This data should be used to implement changes in the orthopaedic community to decrease injuries and disability claims.

"I'm pulling through because of you": injured workers' perspective of workplace factors supporting return to work under the Saskatchewan Workers' Compensation Board scheme.

Research demonstrates sustained return to work (RTW) by individuals on medical leave is influenced by personal and job resources and job demands. Relatively few studies have been conducted in the workers' compensation context that is known to have longer absence durations for RTW. This study sought to illuminate workers' experience as they returned to work following a work injury that was either psychological in nature or involved more than 50 days of disability, with a focus on the co-worker, supervisor, and employer actions that supported their return. Workers in Saskatchewan, Canada, with a work-related psychological or musculoskeletal injury, subsequent disability, and who returned to work in the last three years, were invited to complete an online survey comprising of free-text questions. Thematic analysis was used to explore participants' experiences. Responses from 93 individuals were analysed. These revealed that persistent pain, emotional distress, and loss of normal abilities were present during and beyond returning to work. Almost two-thirds indicated that the supervisors' and co-workers' support was critical to a sustained return to work: their needs were recognized and they received autonomy and support to manage work demands. By contrast, one-third indicated that the support they expected and needed from supervisors and employers was lacking. Workers returning to work lacked personal resources but co-workers' and supervisors' support helped improve confidence in their ability to RTW. Supervisors and employers should acknowledge workers' experiences and offer support and autonomy. Likewise, workers can expect challenges when returning to work and may benefit from cultivating supportive relationships with co-workers and supervisors.

Musculoskeletal disorders and discomfort for female surgeons or surgeons with small hand size when using hand-held surgical instruments: a systematic review

BackgroundWork-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.MethodsThe 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.ResultsUsing 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.ConclusionsThe 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 registrationThe study protocol was registered on PROSPERO (ID: CRD42022283378).

Association of Case Duration with Late vs. Early Physical Therapy Initiation in Treatment of Work-Related Musculoskeletal Injuries: A Retrospective Analysis

Background:Occupational medicine providers treat patients who are injured while working. Conservative management with over-the-counter anti-inflammatory medicines, physical modalities (ice/heat), and activity restrictions are first-line treatment strategies. Physical therapy (PT) is often added to assist with patients’ return to baseline through symptom reduction and restoration of function. PT efficacy on outcomes and healthcare costs has been described in other patient populations but less described in injured worker populations. This study focused on associations between PT timing and case duration for treating musculoskeletal injuries in a regional injured workerpopulation.&#x0D; Methods:A retrospective chart review of 795 patients receiving care at Parkview Occupational Health (POH) for musculoskeletal injuries from 2017-2023 was conducted to determine if early PT was associated with case duration. Patients employed in Indiana and referred to PT within Parkview were included in the study. Age, BMI, and case duration were compared between early vs. late PT groups using two-sampled t-test. Race, sex, smoking status, and injury type were compared using chi-squared tests.&#x0D; Results:The mean case duration (73.41 days) when PT was initiated early (≤ 30 days after date of injury, DOI) was significantly shorter compared to the mean case duration (104.21 days) when PT was initiated late (p&lt;0.0001). Case duration was even shorter (67.61 days) when early PT was defined as ≤14 days after injury (p=0.001). There was no significant difference in case duration (mean difference=9.5 days) between patients initiating PT within 14 days and within 15-30 days (p=0.15). Injury type (back vs. other musculoskeletal injuries) was significantly associated with PT timing (p=0.002).&#x0D; Conclusion/Implications:Future analysis should compare case duration, days of restricted work, advanced imaging utilization, and specialist referral rate between patients with early and late PT initiation. This comparison will aid in development of best practice guidance for treatment of work-related musculoskeletal injuries at POH.

Don't Just Stand There. Rethinking the Ideal Body Posture for Otorhinolaryngologists.

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.

In-hospital complications of work-related musculoskeletal injuries

Background, ObjectivesWork-related musculoskeletal (MSK) injuries are a major contributor to morbidity worldwide and frequently result in hospitalisation. Hospital complications are common, costly, and largely preventable, but relevant data is required to address this. This study aimed to identify the incidence and factors associated with in-hospital complications of work-related MSK injuries. MethodsThis study is based on work-related MSK hospital admission data from Victorian Admitted Episodes Database, 2016–2022. Complications were identified based on ICD-10-AM coding using CHADx (Classification of Hospital Acquired Diagnoses). Negative binomial and logistic regression analyses were performed to identify factors related to in-hospital complications. ResultsIn-hospital complications occurred in 6.3 % of work-related MSK injury admissions. In the adjusted models, ages ≥45 years, female sex, and area-level disadvantage were associated with in-hospital complications. Stay at public (vs private) hospitals, comorbidity, emergency admissions, and general anaesthesia were also associated. Complication rates were higher in hospitalised workers with direct head, neck, and trunk injuries and cumulative MSK disorders than those with direct extremities injuries and acute MSK conditions. The most common complications were cardiovascular, gastrointestinal complications and adverse drug events. ConclusionThis study identified patient, injury and hospital-related characteristics associated with in-hospital complications of work-related MSK injuries for informing prevention strategies and risk estimation by hospital staff and workers' compensation schemes. The results demonstrate a sizable rate of complications given the relatively young and healthy study population.

The role of therapist-patient relationships in facilitating engagement and adherence in upper extremity rehabilitation.

Active patient engagement and adherence are essential for successful rehabilitation outcomes, particularly in complex cases such as work-related musculoskeletal injuries. Although the therapist-patient relationship is a significant component of successful care coordination, there has been limited examination of this relationship within upper extremity musculoskeletal rehabilitation. To explore therapists' perspectives on how the therapist-patient relationship intersects with engagement and adherence in the provision of holistic and collaborative rehabilitation services. Data were collected from four therapists over three months. Descriptive statistics were generated from the Sport Injury Rehabilitation Adherence Scale (SIRAS) and the Rehabilitation Therapy Engagement Scale (RTES) completed by therapists following visits from a sub-sample of patients (n = 14). Weekly semi-structured group interviews (n = 13) were analyzed using an iterative grounded theory-informed process. Emerging themes were identified, refined, and situated within the context of quantitative results. SIRAS scores averaged 14.4 (SD: 1.0) and RTES scores averaged 42.5 (SD: 3.5), indicating high perceived patient engagement and adherence. Four themes emerged from therapist interviews: (1) dynamic power; (2) co-constructed engagement; (3) emotional states; (4) complementary therapy contexts. In this engaged and adherent setting, therapist-patient relationships were complex and intimate, and extended beyond education and physical interventions. Careful management of this relationship was central to active patient participation and engagement. Incorporating holistic techniques may provide more structure for managing and communicating these aspects of care. These findings provide a preliminary understanding of the impact of therapeutic relationships on engagement and collaborative care.

An overview of occupational injuries among female orthopaedic surgeons

IntroductionThe aim of this study was to assess occupational injuries among female orthopaedic surgeons and compare these rates to their male counterparts. MethodsAn electronic survey was developed to assess occupational injuries among female orthopaedic surgeons. Descriptive statistics were analyzed for all survey items, and chi-squared tests and paired t-tests were used when appropriate. Results169 female orthopaedic surgeons completed this survey, the average age was 50 years old. MSK Injuries: Among the 169 responding surgeons, there were a total of 320 work-related musculoskeletal injuries. Non-MSK Occupational Injuries: Female orthopaedic surgeons experience social isolation at much higher rates than their male counterparts (53.8 % and 32.9 % respectively, p < 0.0001) as well as psychological distress since beginning practice (61.5 % and 55.3 % respectively). Additionally, female orthopaedic surgeons report higher rates of burnout (72.2 %, p = 0.01) compared to male orthopaedic surgeons (63.4 %). Female orthopaedic surgeons also sought out counseling from mental health professionals at higher rates than their male counterparts since beginning training (37.3 % and 28.6 % respectively, p = 0.02). 13.1 % of female respondents reported having been diagnosed with cancer since starting practice. Additionally, 94.6 % of female orthopaedic surgeons have experienced a finger stick and 16.1 % of female orthopaedic surgeons have experienced hearing loss since beginning practice. DiscussionThis study assesses the occupational injuries that affect female orthopaedic surgeons’ physical and mental well-being. We found that in comparison to male orthopaedic surgeons, the major differences were found in the psychological and emotional domains. Women reported experiencing burnout and social isolation as well as seeking professional counseling at significantly higher rates than males; however, both genders reported concerningly high numbers. This could suggest that more resources need to be made available to help orthopaedic surgeons cope with the stresses of their demanding profession, with a specific emphasis on reducing work-related stress among female orthopaedic surgeons.

Ergonomics of bronchoscopy: good advice or a pain in the neck?

Interventional pulmonologists require a unique set of skills including precise motor abilities and physical endurance, but surprisingly the application of ergonomic principles in the field of bronchoscopy remains limited. This is particularly intriguing when considering the significant impact that poor ergonomics can have on diagnostic aptitude, income potential and overall health. It is therefore imperative to provide comprehensive education to physicians regarding the significance of ergonomics in their work, especially considering the introduction of advanced diagnostic and therapeutic procedures. By implementing simple yet effective measures (e.g. maintaining neutral positions of the wrist, neck and shoulder; adjusting the height of tables and monitors; incorporating scheduled breaks; and engaging in regular exercises), the risk of injuries can be substantially reduced. Moreover, objective tools are readily available to assess ergonomic postures and estimate the likelihood of work-related musculoskeletal injuries. This review aims to evaluate the current literature on the impact of procedure-related musculoskeletal pain on practising pulmonologists and identify modifiable factors for future research.

Preventing work-related musculoskeletal injuries among oral and maxillofacial surgeons.

Oral and maxillofacial surgeons (OMS) are continually required to adjust position and posture to access the limited surgical field in and around the head and neck, oral cavity, and oropharynx. Very limited data exists that quantifies the burden of musculoskeletal disorders (MSD) among OMS. This exploratory study seeks to address these literature gaps by assessing the prevalence of MSD among OMS. A 12-question survey was designed to investigate the prevalence of MSD for OMS, including residents in training, actively practicing surgeons, and retired surgeons. Seventy-six surveys were distributed and completed in person by surgeons attending professional conferences from September 2018-September 2019. Survey questions included the Baker-Wong Faces pain scale, years in practice, number of hours worked per week, job tenure, pain attributable to work, and age. The Nordic scale identified and delineated anatomic site of musculoskeletal complaints, duration and treatment sought. The most frequently cited sources and locations of pain attributable to occupation were shoulders, neck, and lower back. The risk of MSD symptoms was relatively two-fold [PR = 2.54, 95% CI = 0.90, 7.22] among OMS in practice for more than ten years compared to those in practice less than ten years. After adjusting for age and hours worked per week as potential confounders, the risk of MSD symptoms was higher among OMS in practice for more than ten years compared to those with less than ten years of experience, despite no statistically significant association. OMS are impacted by a high prevalence of MSD. The neck, shoulder, and lower back are the most frequently affected with discomfort and pain. This study found that practicing oral and maxillofacial surgery for more than 10 years is a potential risk factor for experiencing MSD.

Automated Classification of the Phases Relevant to Work-Related Musculoskeletal Injury Risks in Residential Roof Shingle Installation Operations Using Machine Learning

Awkward kneeling in sloped shingle installation operations exposes roofers to knee musculoskeletal disorder (MSD) risks. To address the varying levels of risk associated with different phases of shingle installation, this research investigated utilizing machine learning to automatically classify seven distinct phases in a typical shingle installation task. The classification process relied on analyzing knee kinematics data and roof slope information. Nine participants were recruited and performed simulated shingle installation tasks while kneeling on a sloped wooden platform. The knee kinematics data were collected using an optical motion capture system. Three supervised machine learning classification methods (i.e., k-nearest neighbors (KNNs), decision tree (DT), and random forest (RF)) were selected for evaluation. The KNN classifier provided the best performance for overall accuracy. The results substantiated the feasibility of applying machine learning in classifying shingle installation phases from workers’ knee joint rotation and roof slope angles, which may help facilitate method and tool development for automated knee MSD risk surveillance and assessment among roofers.

Descriptive Epidemiology of Occupational Injuries among urban construction workers – an observation from Eastern India

Introduction Bhubaneswar, Odisha, is seeing a boom in construction activities, with workers from remote areas coming for work. Poverty, and illiteracy, coupled with employment and regular payments make them oblivious to unsafe working conditions. Long hours of heavy work in bad postures affect their musculoskeletal system leading to work-related musculoskeletal injuries. This study aimed to understand the epidemiology of the above injuries among the construction workers in Bhubaneswar Methods It was a work-site-based multistage cross-sectional study, where the sites engaging &gt;=15 workers were selected randomly. A total of 520 workers (consented, &gt;=21 years of age, and in this profession for at least 3 years) were recruited randomly. Data was collected by interviewing the study participants with the help of a pre-tested questionnaire focusing on sociodemographic profiles and relevant epidemiological variables related to occupational injury of urban construction workers. Data entry and analysis were done using SPSS version 20. Results Over 95% of the participants were heavy workers, 23.1% were laborers, 28.1% had &lt; 10 years of experience, and 72.3% were satisfied with their job. A little more than 19% had work-related injuries in the last 3 months. Age, gender, alcohol abuse, better education, lesser work experience, skilled work and job dissatisfaction were found to be statistically significant when associated with workplace injuries. Multivariate analysis revealed only age and lesser duration of working experience in the construction industry were associated with an increase in occupational injuries. Conclusion This study found that younger age, less work experience, male gender, use of alcohol, nature of work and lack of job satisfaction, and a few other factors were associated with work-related injuries. Often their occupational health and injuries get overlooked. Employers should be primarily responsible for their health, safety, and well-being. Suitable legislation and proper implementation would probably facilitate this.

Stress and Prevalence of Musculoskeletal Disorders Among the Nursing Personnel of a Tertiary Hospital Unit in Greece: A Cross-Sectional Study.

Work-related musculoskeletal injuries and disorders (WMSD) are a significant cause of morbidity in the health care sector. Healthcare professionals are routinely exposed to various physical and psychosocial factors that increase the risk of developing a WMSD. Nurses are more susceptible to the manifestation of such disorders. A cross-sectional study was conducted during the second semester of 2020. The Nordic Questionnaire (NMQ) was used to investigate the prevalence of musculoskeletal symptoms, the Short Anxiety Screening Test (SAST) for stress detection, and a data collection sheet was developed for the registration of clinical, demographic, and anthropometric characteristics of the nursing personnel of the tertiary hospital unit of Heraklion, Crete, Greece. A percentage of 82% of nurses had developed at least one musculoskeletal symptom in the last 12 months. The most common anatomical areas at which symptoms were present the last 12 months were the neck (53.9%), shoulders (50.8%), and the lower back (49.5%). The same areas were also the reported anatomical regions, most affected by musculoskeletal symptoms when stress levels were high. Absence from work was associated with the onset of musculoskeletal symptoms (p<0.001), while nurses' financial expenses (out-of-pocket payment) appeared to be associated with the onset of any symptom at 12 months, musculoskeletal symptoms limiting everyday activity at 12 months, and current musculoskeletal symptoms (p=0.001, p=0.002, and p=0.002 respectively). Musculoskeletal disorders were common among the nursing personnel. Higher levels of stress were related with a higher prevalence of musculoskeletal symptoms.

Prevalence and Spectrum of Occupational Injury Among Orthopaedic Surgeons: A Cross-Sectional Study.

An electronic survey was developed to assess both physical and mental occupational hazards among orthopaedic surgeons. Descriptive statistics were analyzed for all survey items and compared using chi-square and paired t tests, as appropriate. The 1,645 responding orthopaedic surgeons (7% response rate) reported a total of 2,702 work-related musculoskeletal injuries, 17.9% of which required surgical treatment. Of the 61 who filed a disability claim, only 66% returned to work and 34% retired early. Additionally, 17.4% of respondents reported having been diagnosed with cancer since starting practice, and 93.8% reported experiencing a finger stick at some point in their career. Over one-half (55.8%) had experienced feelings of psychological distress since beginning practice, and nearly two-thirds (64.4%) reported burnout from work. This study captured a spectrum of occupational injuries that pose longitudinal risks to an orthopaedic surgeon's physical and mental well-being. Our hope is that this analysis of occupational hazards will help to raise awareness among the orthopaedic and medical communities and lead to efforts to reduce these risks. Prognostic Level IV.

Positive, but not negative, treatment outcome expectancies mediate the relation between depressive symptoms and treatment-related pain reduction.

Previous research has shown that depression is associated with adverse recovery outcomes following work-related musculoskeletal injury. Treatment outcome expectancies have also been shown to predict recovery trajectories following musculoskeletal injury. The present study examined the role of positive and negative treatment outcome expectancies as mediators of the relation between depressive symptoms and treatment outcome for individuals receiving physical therapy for a musculoskeletal injury. The study sample consisted of 153 individuals who had sustained a work-related musculoskeletal injury to the back or neck within 6 months of enrolment. Participants completed self-report measures of depressive symptom severity, pain severity, and treatment outcome expectancies prior to treatment; pain severity was assessed again after 4 weeks of treatment. The results of this study were consistent with previous research showing significant relations between depressive symptom severity, pain severity and treatment outcome expectancies. Bootstrapping mediation analyses separately assessed the mediating roles of positive and negative treatment outcome expectancies on the relation between depressive symptoms and pain severity. Findings revealed that positive treatment outcome expectancies mediated the relation between depressive symptoms and pain severity, whereas negative treatment outcome expectancies did not. Discussion addresses potential pathways through which positive treatment outcome expectancies might influence pain outcomes. The findings suggest that intervention techniques aimed at increasing positive treatment outcome expectancies, rather than decreasing negative treatment outcome expectancies, might contribute to better recovery outcomes for individuals experiencing pain and depressive symptoms following a work-related musculoskeletal injury.

Comparisons of Trunk Motions and Low Back Injury Risk between Alternative Hotel Room Cleaning Methods.

Hotel room cleaners frequently report job-related pain, with high rates of work-related musculoskeletal disorder injuries established for this group of workers. Surprisingly, there is limited published research documenting the impact of interventions to reduce ergonomic-related injury risks specific to hotel room cleaners' job tasks. In this study focused on hotel bathroom-cleaning and furniture-dusting tasks, twelve experienced hotel room cleaners used their standard method and a risk-reduction method-a tool with a handle that could extend, to perform these tasks. The female study participants' average age was 45.3 (SD 8.7) years with an average of 10 years of work experience as cleaners (range: 0.8-26.0 years). Trunk kinematics and a low back injury risk assessment were measured using the Lumbar Motion Monitor. All study metrics were significantly reduced when cleaning tasks involved use of adjustable, long-handled tools (p < 0.05). This study demonstrated that commonly available cleaning and dusting tools with extendable handles can significantly reduce low back injury risk among hotel room cleaners and potentially reduce injury risk to other body parts known to be the site of musculoskeletal disorders in this workforce. The study findings suggest that cleaning or housekeeping jobs in other industries where these same tasks are performed could benefit from use of extended-handle tools like those investigated here.
