A new approach for the implementation of ergonomics in sonography to prevent work-related musculoskeletal disorders (ErgoSon). J Occup Med Toxicol 2025; 20:11.

Abstract
BACKGROUND A substantial body of research has documented a high prevalence of neck, shoulder, wrist, and back pain among sonography users. However, the specific postures that contribute to these complaints have scarcely been systematically investigated, to date. This proposed study offers a novel method to record users' body posture during sonography examinations kinematically and to survey the complaints of sonography users in various specialities. Using this data, well-founded ergonomic recommendations for the prevention of work-related musculoskeletal disorders (WRMSDs) will be developed. METHODS A minimum of 38 study participants across two groups (19 beginners; 19 experienced) per speciality (head and neck sonography, abdominal sonography, cardiac sonography, musculoskeletal sonography, and obstetric/gynaecological sonography) will be assessed using kinematic whole-body (including finger movements) analysis based on inertial motion capture. Subsequently, ergonomic risk will be determined by integrating the quantitative data into the Rapid Upper Limb Assessment (RULA). Moreover, a questionnaire on musculoskeletal complaints and ergonomics in sonography will be used in certified sonography courses, ultrasound-based centres, and university teaching. The primary outcome measures of this proposed study include typical tasks based on joint angles and assessment using RULA scores. In addition, the prevalence of WRMSDs will be recorded. The Mann-Whitney-U test will be employed to calculate the differences between the two study groups in each speciality. In addition, inferential statistical comparisons will be conducted for continuous data using confidence bands; the statistical parametric mapping method will be employed here. The significance level will be set at p = 0.05. CONCLUSIONS This article proposes a study (or series of studies) to describe the continuous ergonomic risk for typical tasks across different disciplines of sonography and to identify increased ergonomic risks. Such studies offer significant potential for preventing WRMSDs. The insights gained could inform the future design of prevention programmes and the development of recommendations for action, as well as teaching sonography users an ergonomically optimised way of working. The results could suggest that ergonomics training is incorporated more thoroughly into ultrasound training curricula to minimise health risks for future users.

Abstract
INTRODUCTION The job of sonographers exposes them to numerous ergonomic risk factors, making the sonography profession one of the high-risk job groups vulnerable to musculoskeletal disorders (MSDs). The present systematic review and meta-analysis specifically examined the prevalence of MSDs among sonographers. MATERIALS AND METHODS The present review study was carried out in accordance with the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. The protocol of the study was registered in the international prospective register of systematic review (PROSPERO) with the code CRD42024507972. Searches were conducted in databases including PubMed, Scopus, Web of Science, Science Direct, SID, ISC, and Google Scholar, without imposing a time limit until February 7th, 2024. The random-effects model was employed for meta-analysis, and the I2 index was used to assess heterogeneity among studies. Finally, data analysis was performed using STATA (version 14). RESULTS Based on the search in different databases, a total of 4367 articles were identified. Finally, after screening, selecting, and quality evaluation of the studies, 30 studies were considered for meta-analysis in which 13,916 sonographers were examined. According to the results of the meta-analysis, the overall prevalence of MSDs among sonographers was reported as 75.80% (95% CI: 65.37-86.23, I2 = 99.7%, P < 0.001). Additionally, the prevalence rates of these disorders in the neck (63.73%), shoulder (60.13%), upper back (53.69%), lower back (49.84%), wrist (44.41%), elbow (27.46), hip (24.93%), knee (19.59), and ankle (16.92%) were determined. CONCLUSION Given the relatively high prevalence of MSDs among sonographers and the importance of reducing specific risk factors associated with their duties, it is recommended to consider solutions such as carrying out ergonomic assessments and interventions, as well as providing training programs and appropriate corrective exercises to mitigate MSDs among sonographers.

Abstract
PURPOSE The ultrasound specialists face a substantial issue with work-related musculoskeletal disorders (WMSDs), characterized by occupation-related pain, reaching an estimated frequency of up to 90.5%. The type and location of pain vary depending on the sonographers specialty and the specific anatomical areas being examined. Our study aimed to assess the prevalence and intensity of pain among Polish doctors from various specialties conducting ultrasound examinations. MATERIALS AND METHODS The study has been performed between July and December 2023, involving 90 participants (51.9% women) actively practicing ultrasound diagnostics. The data collection process utilized a structured questionnaire developed by the researchers for this study. The questionnaire covered personal factors, including gender and age, and work-related aspects like workplace, specialty, sonography experience, and the types of examinations conducted. Statistical analysis involved both descriptive statistics and correlation analysis. RESULTS The age distribution ranged from 26 to 74 years, with mean (SD) of 43.1 (12.2) years. The leading specialties among physicians were radiology (22.2%) and internal medicine (22.2%). Among all physicians, 65.6% reported pain during or after ultrasound scans, with a mean (SD) pain intensity of 6.17 (2) in a 1-10 scale. The analysis indicated no correlation between age and gender and the occurrence of discomfort. CONCLUSIONS WMSDs pose a significant risk to Polish sonographers, especially those specializing in vascular surgery, general surgery and obstetrics and gynecology specialties. The study underscores a notable deficit, with only 10% of the personnel reporting training in ergonomics for ultrasound work.

Abstract
The early detection of fatal diseases is crucial for medical diagnostics and treatment, both of which benefit the individual and society. Portable devices, such as thermometers and blood pressure monitors, and large instruments, such as computed tomography (CT) and X-ray scanners, have already been implemented to collect health-related information. However, collecting health information using conventional medical equipment at home or in a hospital can be inefficient and can potentially affect the timeliness of treatment. Therefore, on-time vital signal collection via healthcare monitoring has received increasing attention. As the largest organ of the human body, skin delivers significant signals reflecting our health condition; thus, receiving vital signals directly from the skin offers the opportunity for accessible and versatile non-invasive monitoring. In particular, emerging flexible and stretchable electronics demonstrate the capability of skin-like devices for on-time and continuous long-term health monitoring. Compared to traditional electronic devices, this type of device has better mechanical properties, such as skin conformal attachment, and maintains compatible detectability. This review divides the health information that can be obtained from skin using the sensor aspect's input energy forms into five categories: thermoelectrical signals, neural electrical signals, photoelectrical signals, electrochemical signals, and mechanical pressure signals. We then summarize current skin-wearable health monitoring devices and provide outlooks on future development.

Abstract
OBJECTIVE Given the economic burden of work-related neck pain and disability, it is important to understand its time course and associated risk factors to direct better management strategies. This study aimed to identify the 1-year trajectories of work-related neck disability in a high-risk occupation group such as sonography and to investigate which baseline biopsychosocial factors are associated with the identified trajectories. METHODS A longitudinal study was conducted among 92 sonographers with neck disability assessed at 3 time points-baseline, 6 months, and 12 months-using the Neck Disability Index. Baseline biopsychosocial measures included individual characteristics (demographics and physical activity levels), work-related physical and psychosocial factors (eg, ergonomic risk, workplace social support, job satisfaction), general psychological features (depression, anxiety, pain catastrophizing, and fear-avoidance beliefs), and quantitative sensory testing of somatosensory function (cold and pressure pain thresholds at neck and tibialis anterior, and temporal summation). RESULTS Two distinct trajectories of neck disability were identified, including a "low-resolving disability" trajectory showing slow improvement toward no disability (64.8%) and a "moderate-fluctuating disability" trajectory characterized by persistent moderate disability with a small fluctuation across time (35.2%). The trajectory of moderate-fluctuating disability was associated with more severe symptoms, lower vigorous physical activity, higher ergonomic risk, remote cold hyperalgesia, widespread mechanical hyperalgesia, heightened pain facilitation, and several psychosocial factors such as anxiety, depression, lower job satisfaction, and lower workplace social support at baseline. CONCLUSION Over one-third of sonographers were at risk of developing a moderate-fluctuating disability trajectory. This unfavorable trajectory was associated with low physical activity level, poor ergonomics, psychosocial distress, and central sensitization at baseline. IMPACT This study has important implications for the management of neck disability in workers. Addressing modifiable factors including low vigorous physical activity, poor ergonomics, anxiety, depression, and lack of workplace social support may improve the trajectory of work-related neck disability.

Abstract
This article discusses the importance of conducting a longitudinal data collection concerning well-being and the risk for work-related musculoskeletal injuries (WRMSI) among sonographers and vascular technologists. There is a need for changes in the manner that sonographic work is done, but this should be nested in empirical evidence. This gives the rational for conducting the study titled Documenting the overall wellness of ultrasound users and the risk of progressive WRMSI: A national longitudinal study. The objective of this longitudinal work is to better understand collective practice patterns and examine the relationship of sonographic work conditions and performance to the user’s health and well-being. This symposium provides the foundational understanding of the strength of this type of study and how it may help to influence behavior and organizational change.

Abstract
BACKGROUND: Work-related musculoskeletal disorders (WMSDs) among sonographers have raised significant concerns in recent years. OBJECTIVES: This study aimed to estimate the prevalence of WMSDs and identify risk factors for WMSDs among sonographers. To date, there is little research on WMSDs among sonographers in Saudi Arabia. Therefore, this study aimed to contribute to the Saudi literature by filling this gap. METHODS: A cross-sectional study was conducted among sonographers (n = 98) working in four major governmental hospitals in the city of Al-Ahsa, Saudi Arabia. The participants completed a validated, self-administered questionnaire that focused on the analysis of musculoskeletal symptoms among sonographers. RESULTS: The mean age of the respondents was 35.5±9 years. The majority of the participants were female (71.4%), non-Saudi (51%), and working as technicians (49%). The prevalence rates of shoulder and neck disorders among the participants were 65.3% and 57.1%, respectively. Gender (female), job title (sonography technicians), and years of experience (seasoned sonographers) were identified as risk factors for WMSDs. CONCLUSIONS: Among the studied sonographers, WMSDs were a significant, common problem. Being female, being a sonography technician, and being a seasoned sonographer were identified as risk factors for these disorders. Preventive measures should be implemented to reduce the risk of WMSDs in this occupational setting.

Abstract
ABSTRACT Sonographers experience stress-related musculoskeletal injuries at alarming rates. The magnitude of the problem has resulted in substantial economic and human costs. Early efforts, such as the transposition of office ergonomic models to the ultrasound suite, have been only marginally successful because of the vast difference between clerical and sonography work demands. In addition, although the issue has attracted the attention of professional sonographer societies, equipment manufacturers, and governmental agencies, such as the OSHA (Occupational Safety and Health), the causative mechanisms by which sonographers are injured remain inadequately addressed. A definitive ergonomic solution has been elusive.With the help of occupational therapists and biomechanical engineers, we have developed a number of possible ergonomic modifications of ultrasound equipment. We explain the rationale behind these approaches to transducer design and assess the strengths and deficiencies of each.

Abstract
Background: The repetitive and prolonged exertion of grip and pinch strength are current among carpet weaver tasks. The three objectives of this study were (1) to investigate the relationship between symptoms of musculoskeletal disorders and grip and pinch strength of carpet weavers in carpet weaving workshops in Kerman province, (2) to compare the grip and pinch strength of carpet weavers with normal values, and (3) to identify the relationship between hand postures of carpet weavers during work and force exertion. Methods: In this cross-sectional study, grip strength and key, tip and palmar pinch strengths of 101 female carpet weavers aged 20 to 71 years were measured in Kerman province, in 2018. Nordic Musculoskeletal Questionnaire (Extended version) was also used to evaluate musculoskeletal disorders. Results: Bivariate and multivariate linear regression analyses showed that participants who suffered from musculoskeletal disorders had lower grip and pinch strength than others and this decrease was statistically significant in upper back, wrists/hands, and knees. Moreover, there was a significant difference between grip and three types of pinch strength of carpet weavers and normal values. Furthermore, for both hands, the grip strength in the position recommended by American Society of Hand Therapists was significantly greater than that in the normal position carpet weavers usually adopt. Conclusion: Based on the results, the high prevalence of musculoskeletal disorders has led to a significant decrease in the grip and pinch strength of carpet weavers. Therefore, it is necessary to undertake ergonomic interventions in designing the carpet weaving workstation.

Abstract
The aim of this study was to explore the ergonomic challenges, the needs and reservations related to robot-assisted ultrasound for obstetric sonographers and thereby to provide information for the design of robotic solutions. A mixed-method design was used, where data from the obstetric sonographers and their immediate managers from 18 out of a Danish total of 20 obstetric departments was collected. The data was collected through a survey and interviews. 98.1% of the obstetric sonographers experienced ache, pain or discomfort related to scans. The most frequent cause for the sonographers' ergonomic challenges were the patients' physique (93,52%) and the need to obtain good image quality (83,33%). These reasons are non-controllable parameters for the obstetric sonographers and requires a solution, which ergonomically supports the sonographers in these situations. All of the interviewed obstetric sonographers (n = 8) and immediate managers (n = 3) claimed they were interested in testing a solution based on robot-assisted ultrasound.

Abstract
Inclinometry and video analyses can provide objective measures of physical workloads. The study aim was to measure and observe arm, back and head postures and movements among forklift truck operators (FLTOs) during a working day, analyzing differences between types of forklift trucks and to assess reported workload and health. Twenty-five male FLTOs in a high-level warehouse were randomly included. The data collected comprised technical measurements, video analyses of postures and movements, and a questionnaire measuring health, pain and workload. On average, the FLTOs rotated their head more than 45°, in total, 232 times/h. Video analysis revealed that FLTOs periodically drive the forklift truck sideways with the head rotated in the direction of travel, and in periods look upwards, in which the head is highly rotated and extended. Inclinometry and observations during the working day has the potential to be a valuable part of risk assessment promoting occupational safety and health.

Abstract
Dynamic imaging of the skeletal muscles used to be strenuous and often impossible to perform manually. Accordingly, long-term dynamic musculoskeletal imaging has not been performed. The feasibility of long-term dynamic musculoskeletal functional analysis using hands-free ultrasound will be demonstrated in ten healthy endurance runners. After every kilometer, the vastus lateralis muscle was imaged whilst running using a fixated probe connected to a smart phone. The image quality was quantified by estimation of the probe-skin contact preservation and the field-of-view stability. Moreover, the pennation angles and muscle thicknesses were computed automatically. Long-term dynamic acquisition was successful in nine out of ten runners. Probe-skin contact loss ranged between 0 and 57% of the gait cycle. The biggest change in field-of-view occurred during the first kilometer with an average decline in complex-wavelet structural similarity index of 0.21, followed by an onward total decrease of 0.09, on average. The mean pennation angle and thickness were approximately constant, with the average fluctuation being 0.94 degrees and 0.11 cm, respectively. The feasibility of long-term musculoskeletal function analysis has been demonstrated, with probe-skin contact loss the main limiting factor. Dynamic, hands-free ultrasound might enable research for a more profound insight in the prevention and rehabilitation of musculoskeletal injuries.

Abstract
Introduction. Research on the prevalence of and potential risk factors associated with work-related musculoskeletal disorders (WMSDs) among sonographers in China is scarce. More evidence is required to mitigate WMSDs among sonographers in Guangdong province, China. Objective. The present study aimed to determine the prevalence of and potential associated factors for WMSDs among sonographers in general hospitals in Guangdong province, China. Methods. A self-reported questionnaire was distributed to sonographers from 14 general hospitals selected by convenience sampling in Guangdong province. Multivariate logistic regression was used to analyze associations between potential factors and WMSDs in the most affected body areas. Results. In this study, 249 sonographers completed the questionnaire, yielding a response rate of 75.5%. The 12-month period prevalence of WMSDs was 95.2%, and the four most affected regions were the right shoulder (81.1%) followed by the neck (74.7%), right wrist/hand (59.4%) and lower back (57.0%). Among symptomatic sonographers, 31.2% were absent from work. Gender, years of experience, number of patients per day, shift type and lumbar support were associated with WMSDs in the most affected regions. Conclusion. Lower workload, more regular rest breaks and good ergonomics of working conditions are encouraged to alleviate WMSDs among sonographers in Guangdong province.

Abstract
Background Exercise stress echocardiography is clinically used to assess cardiovascular diseases. For accurate cardiac evaluation, a stable field-of-view is required. However, transducer orientation and position are difficult to preserve. Hands-free acquisitions might provide more consistent and reproducible results. In this study, the field-of-view stability and variability of hands-free acquisitions are objectively quantified in a comparison with manually obtained images, based on image structural and feature similarities. In addition, the feasibility and consistency of hands-free strain imaging is assessed. Methods In twelve healthy males, apical and parasternal images were acquired hands-free, using a fixation device, and manually, during semi-supine exercise sessions. In the final ten seconds of every exercise period, the image structural similarity and cardiac feature consistency were computed using a steerable pyramid employing complex, oriented wavelets. An algorithm discarding images displaying lung artifacts was created. Hands-free strain consistency was analyzed. Results Hands-free acquisitions were possible in 9 of the 12 subjects, whereas manually 10 out of 12 could be imaged. The image structural similarity was significantly improved in the hands-free apical window acquisitions (0.91 versus 0.82), and at least equally good in the parasternal window (0.90 versus 0.82). The change in curvature and orientation of the interventricular septum also appeared to be lower in the hands-free acquisitions. The variability in field-of-view was similar in both acquisitions. Longitudinal, septal strain was shown to be at least as consistent when obtained hands-free compared to manual acquisitions. Conclusions The field-of-view was shown to be more or equally stable and consistent in the hands-free data in comparison to manually obtained images. The variability was similar, thus respiration- and exercise-induced motions were comparable for manual and hands-free acquisitions. Additionally, the feasibility of hands-free strain has been demonstrated. Furthermore, the results suggest the hands-free measurements to be more reproducible, though further analysis is required.

Abstract
Background Sonographers have reported a high occurrence of musculoskeletal pain for more than 25 years. Assessments of occupational risk factors have previously been based on cross-sectional surveys. The aim of this longitudinal study was to determine which factors at baseline that were associated with neck/shoulder and elbow/hand pain at follow-up. Methods A questionnaire was answered by 248 female sonographers at baseline and follow-up (85% of the original cohort). 208 were included in the analyses. Physical, visual, and psychosocial work-related conditions were assessed at baseline. Pain in two body regions (neck/shoulders and elbows/hands) was assessed at both baseline and follow up. Results Pain at baseline showed the strongest association with pain at follow-up in both body regions [prevalence ratio (PR) 2.04; 95% confidence interval (CI) 1.50–2.76], for neck/shoulders and (PR 3.45; CI 2.29–5.22) for elbows/hands. Neck/shoulder pain at follow-up was associated with inability of ergonomic adjustments at the ultrasound device (PR 1.25; CI 1.05–1.49), a high mechanical exposure index (PR 1.66; CI 1.09–2.52), and adverse visual conditions (PR 1.24; CI 1.00–1.54) at baseline. Moreover, among participants with no neck/shoulder pain at baseline, high job demands (PR 1.78; CI 1.01–3.12), and a high mechanical exposure index (PR 2.0; CI 0.98–4.14) predicted pain at follow-up. Pain in the elbows/hands at follow-up was associated with high sensory demands at baseline (PR 1.63; CI 1.08–2.45), and among participants without pain at baseline high sensory demands predicted elbow/hand pain at follow-up (PR 3.34; CI 1.53–7.31). Conclusion Pain at baseline was the strongest predictor for pain at follow-up in both body regions. We also found several occupational factors at baseline that were associated with pain at follow-up: inability to adjust equipment, adverse visual conditions, a high MEI, high job demands and high sensory demands. These results point at a possibility to influence pain with better ergonomics.

Abstract
PURPOSE In dynamic musculoskeletal sonography, probe fixation can contribute to field of view (FOV) consistency, which is necessary for valid analysis of architectural parameters. In this volunteer study, the achieved FOV consistency in fixated ultrasonography was quantified and compared with freehand acquisition. METHODS During five resting periods during cycling exercise, longitudinal B-mode images of the vastus lateralis (VL) muscle were acquired on one thigh with a fixated probe, and by two trained observers on the other thigh. In each acquisition, the structural similarity compared to the first resting period was determined using the complex wavelet structural similarity index (CW-SSIM). Also, the pennation angle of the VL was measured. Both CW-SSIM and pennation angle were compared between fixated and freehand acquisition. Furthermore, the compression of tissue by the probe fixation was measured. RESULTS In fixated acquisition, a significantly higher structural similarity (p < 0.05) and an improved repeatability of pennation angle measurement were obtained compared to freehand acquisition. Probe fixation compressed muscle tissue by 12% on average. CONCLUSIONS Quantification of the structural similarity showed an increase in FOV consistency with sonography compared to freehand acquisition. The demonstrated feasibility of long-term fixated acquisition might be attractive in many medical fields and sports, and for reduction of work-related ergonomic problems among sonographers.

Abstract
For more than two decades, surveys of imaging technologists have consistently reported high prevalence of work-related musculoskeletal discomfort (WRMSD). Yet, workplace intervention research involving sonographers is limited. In this study, a transdisciplinary team of researchers used a participatory approach to work with diagnostic medical sonographers (DMS) and vascular technologists (VT) to identify needs and opportunities for developing new approaches to work that will reduce sonographers’ exposures to WRMSD risk factors. In this paper, we describe the approach and the resulting identified needs. We also describe the prototyping and testing of two work approaches that target specific needs of DMS and VT, respectively. We would like designers, manufacturers, engineers, and ergonomists, in collaboration with sonographers and their managers, to recognize this area of opportunity and come together to apply their knowledge of biomechanics and design in developing useful and usable workplace interventions (solutions) to reduce sonographers’ WRMSD risk factor exposure.

Abstract
Background Echocardiography involves strenuous postures of the upper limbs. This study explored the physical workload in the neck and upper limbs in sonographers performing echocardiography, and the extent to which the workload differs from than in other work tasks (other sonographic examinations, and nonsonographic tasks). Methods The physical load was assessed by inclinometry, goniometry, and electromyography methods in 33 female sonographers during authentic work using three different echocardiography techniques and other work tasks. Results Echocardiography was characterized by low velocities of the head, arms, and wrists, and a low proportion of muscular resting time in the forearms, in the transducer limb, and the computer limb. The transducer limb was more elevated in one of the techniques, but this technique also involved a higher proportion of muscular resting time of the trapezius muscle. We also found a high proportion of awkward wrist postures in the transducer wrist in all three techniques; in one due to prolonged flexion, and in the others due to prolonged extension. Other work tasks were less static, and were performed with higher upper arm and wrist velocities. Conclusion None of the three echocardiography techniques was optimal concerning physical workload. Thus, to achieve more variation in physical load we recommend that the equipment be arranged so that the sonographer can alternate between two different techniques during the workday. We also propose alternation between echocardiography and nonsonographic tasks, in order to introduce variation in the physical workload. Clinical expertise should be used to achieve further improvements.

Abstract
Purpose
The purpose of this paper is to describe the self-reported long-term conditions of medical officers and allied health staff working in a regional public health service in northern Australia and how these conditions are managed.
Design/methodology/approach
A cross-sectional survey design was used. The sample was all medical officers and allied health staff employed in mid-2015.
Findings
Of the 365 respondents, 217 (59.5 per cent) reported having at least one long-term condition. There was a statistically significant association between professional group and the number of long-term conditions reported, χ2=10.24, p<0.05. A greater proportion of medical officers (n=29, 43.9 per cent) reported having only one long-term condition compared with allied health staff (n=36, 24.5 per cent). The top four categories of conditions were respiratory, musculoskeletal, mental health and episodic and paroxysmal, although the patterns varied amongst the professional groups, and across age groups. Respondents usually managed their main long-term conditions with personal strategies, rarely using workplace strategies.
Research limitations/implications
Although somewhat low, the response rate of 32 per cent was similar to previous surveys in this health service. Since this survey, the health service has implemented a broad Health and Wellness Programme to support their qualified workforce. Future evaluations of this programme will be undertaken, including whether the programme has assisted health professionals to manage their long-term conditions.
Practical implications
There is an urgent need for targeted, workplace-based health promotion strategies to support staff with long-term conditions. Such strategies would complement self-management approaches, and also provide an important recruitment and retention initiative.
Originality/value
This study adds empirical evidence regarding the long-term conditions among health professionals and their self-management strategies. Little is known about the long-term conditions among the various health professional groups and the findings thus make an important contribution to the existing literature.
