Background: Musculoskeletal disorders significantly affect healthcare professionals, particularly physiotherapists, due to the physical demands of their work. The link between physical ailments and psychological distress is especially prominent in clinical settings. Objectives: To assess the prevalence of work-related low back pain (LBP), stress, anxiety, and depression among physiotherapists in Saudi Arabia, and to identify associated local risk factors. Methods: A cross-sectional study using convenience sampling included 710 licensed physiotherapists across Saudi Arabia. Participants completed an online survey containing demographic data and the validated measures, including the Visual Analog Scale (VAS) for pain, the Oswestry Disability Index (ODI), and the Depression, Anxiety, and Stress Scale-21 (DASS-21) for psychological distress. Data were analysed using descriptive statistics, chi-square tests, correlation, and regression analyses. Results: Of 710 responses, 697 were valid; 378 physiotherapists reported work-related LBP. The mean pain intensity was 4.6 (SD = 1.6), with 54.2% experiencing moderate to severe disability. Mental health results showed 49.7% had depressive symptoms and 33.9% experienced some level of anxiety. Significant correlations were observed between disability and psychological distress (anxiety: r = 0.382; depression: r = 0.375; stress: r = 0.406; all p < 0.001). Regression analyses indicated psychological distress significantly predicted disability, with R² values ranging from 0.125 to 0.248, being higher among inpatient physiotherapists. Conclusions: This study reveals a high prevalence of LBP and psychological distress among Saudi physiotherapists, with stress being the strongest predictor of LBP severity. Integrated ergonomic and mental health interventions, including workplace wellness programs and psychological support, are recommended to reduce risks and promote a healthier, more sustainable physiotherapy workforce.

Work-related musculoskeletal disorders (WMSDs) are among the most prevalent occupational health issues, particularly affecting public transport drivers due to prolonged sitting, constrained postures, and poorly adaptable cabins. This study addresses the ergonomic risks associated with tram driving, aiming to evaluate biomechanical load and postural stress in relation to drivers’ anthropometric characteristics. A combined methodological approach was applied, integrating two standardized observational tools—RULA and REBA—with anthropometric modeling based on three representatives European morphotypes (SmallW, MidM, and TallM). ErgoFellow 3.0 software was used for digital posture evaluation, and lumbar moments at the L4/L5 vertebral level were calculated to estimate lumbar loading. The analysis was simulation-based, using digital human models, and no real subjects were involved. The results revealed uniform REBA (Rapid Entire Body Assessment) and RULA (Rapid Upper Limb Assessment) scores of 6 across all morphotypes, indicating moderate to high risk and a need for ergonomic intervention. Lumbar moments ranged from 51.35 Nm (SmallW) to 101.67 Nm (TallM), with the tallest model slightly exceeding the recommended ergonomic thresholds. These findings highlight a systemic mismatch between cabin design and user variability. In conclusion, ergonomic improvements such as adjustable seating, better control layout, and driver education are essential to reduce the risk of WMSDs. The study proposes a replicable methodology combining anthropometric, observational, and biomechanical tools for evaluating and improving transport workstation design. Full article

Osteoarthritis (OA) is a leading cause of disability worldwide and is characterized by the gradual degradation of articular cartilage in weight-bearing joints, notably the knees and hips. However, the primary morphological and anatomical determinants of the disease onset and progression remain unclear. This narrative overview examines how variations in cartilage thickness—traditionally viewed as a biomechanical protective feature—can paradoxically compromise metabolic homeostasis during prolonged sedentary behavior. Intriguingly, compelling evidence suggests that despite its superior load-bearing capacity, thicker cartilage faces greater challenges in solute transport, a limitation further exacerbated by the formation of diffusion-resistant boundary layers at the cartilage–fluid interface during immobilization. This phenomenon restricts nutrient influx and impedes waste clearance, leading to the accumulation of catabolic byproducts in deep cartilage zones and accelerated extracellular matrix breakdown, potentially influencing OA pathogenesis. By critically synthesizing current debates on mechanical loading with emerging data on metabolic dysregulation, particularly nutrient diffusion limitations, this analysis underscores the urgent need for targeted investigation of synovial–cartilage interface dynamics and chondrocyte metabolism under low-motion conditions. This study further advocates for strategic research focusing on often-overlooked, silent metabolic imbalances among sedentary populations and recommends early-intervention strategies, such as periodic joint mobilization, ergonomic adaptations, and public-health campaigns, to reduce prolonged sitting, preserve joint function, and guide more effective prevention and management approaches for non-traumatic OA in contemporary contexts.

Background: Lower back pain (LBP) is defined as any recurring lumbar pain between the rib cage and the buttocks present at the time of the study. This study investigated the point prevalence, associated risk factors, and degree of disability of LBP among medical students at Alfaisal University, Riyadh, Saudi Arabia. Methods: A cross-sectional study evaluated 331 medical students using the Oswestry Disability Index (ODI; used to gauge LBP degree of disability) supplemented with demographic and lifestyle questions. The respondents were mostly first-year, female, and between the ages of 17 and 21 years. Results: Analysis uncovered that Female students, extended durations of phone usage, and those who did not exercise were more likely to experience LBP (p < 0.001; p = 0.042; p = 0.001). A higher degree of disability was associated with participants older than 21 years, who used their devices for extended periods, and who slept less (β = 0.170, p = 0.006). While most students experienced LBP (73.4%), the ODI revealed that the majority were not deemed disabled (56.9%). Factors associated with LBP prevalence were not necessarily associated with a higher degree of disability per the ODI. Conclusions: LBP is highly prevalent among medical students, with several associated risk factors. Female medical students remain a significant at-risk group. These findings highlight the need for a broader intervention against LBP, such as ergonomic and lifestyle improvements that consider a multitude of factors. Full article

(1) Background: Work-related musculoskeletal disorders (WMSDs) are a major occupational health concern in the construction industry owing to the physically demanding tasks and poor ergonomic conditions present. Limited data exist on the prevalence of WMSDs and their ergonomic determinants among construction workers in India. This study investigated the prevalence of work-related musculoskeletal disorders (WMSDs) and the associated ergonomic risk factors among construction workers in India. (2) Methods: This cross-sectional study was conducted among 250 construction workers in India. Data on musculoskeletal disorders were collected using the Nordic Musculoskeletal Questionnaire (NMQ), and ergonomic risk was assessed using the Rapid Entire Body Assessment (REBA) tool. Logistic regression was used to identify factors associated with WMSDs, and Spearman’s correlation was used to assess the relationship between the REBA scores and the number of affected body regions. (3) Results: The prevalence of WMSDs was 60.4%. The most affected regions were the lower back (48%), knees (45%), shoulders (40%), and the neck (30%). The REBA scores indicated that 60% of the workers were at high or very high ergonomic risk and 30% at medium risk. Workers in the high/very high-risk category had significantly higher odds of developing WMSDs (OR = 4.5, 95% CI: 1.8–11.2, p = 0.001). Age above 40 years was also significantly associated with WMSDs (OR = 3.5, 95% CI: 1.2–10.2, p = 0.02). (4) Conclusions: This study demonstrated a high prevalence of WMSDs among Indian construction workers and established a clear association with poor ergonomic conditions. Targeted ergonomic interventions, including posture improvement, tool redesign, and safety training, are essential for reducing the risk of WMSDs in this population. Full article

Craniofacial deformities, particularly craniosynostosis, present significant surgical challenges due to complex anatomy and the need for individualised, high-precision interventions. Augmented reality (AR) has emerged as a promising tool in craniofacial surgery, offering enhanced spatial visualisation, real-time anatomical referencing, and improved surgical accuracy. This review explores the current and emerging applications of AR in preoperative planning, intraoperative navigation, and surgical education within paediatric craniofacial surgery. Through a literature review of peer-reviewed studies, we examine how AR platforms, such as the VOSTARS system and Microsoft HoloLens, facilitate virtual simulations, precise osteotomies, and collaborative remote guidance. Despite demonstrated benefits in feasibility and accuracy, widespread clinical adoption is limited by technical, ergonomic, financial, and training-related challenges. Future directions include the integration of artificial intelligence, haptic feedback, and robotic assistance to further augment surgical precision and training efficacy. AR holds transformative potential for improving outcomes and efficiency in craniofacial deformity correction, warranting continued research and clinical validation. Full article

Background: Musculoskeletal (MSK) discomfort is a significant occupational hazard for eye care professionals, including ophthalmologists, who report high rates of MSK discomfort. This systematic review investigated the impact of various interventions, such as regular exercise, posture-correcting aids, and surgical heads-up displays, on reducing MSK pain in the operating room. Methods: This review was reported following PRISMA guidelines and was prospectively registered in the PROSPERO database (CRD42024559189). A systematic literature search was conducted of Embase, MEDLINE, and Web of Science from inception to 2024. Included studies were categorized as exercise modifications, equipment modifications, or training aids. All MSK pain-related outcomes from any time point were extracted. Risk of bias was assessed using the Murad tool, the Cochrane risk-of-bias tool for randomized trials (RoB 2), and the Risk Of Bias In Non-Randomized Studies-of Interventions (ROBINS-I) tool. Results: The systematic search strategy identified 2276 studies, of which 53 qualified for full-text screening with 13 resultant studies including 712 eyecare specialists. Physical activity was found unanimously to reduce MSK pain, with favourable evidence for the utilization of posture-correcting aids. There was mixed—but mostly favourable—evidence for the use of surgical heads-up displays. Conclusions: Exercise modifications, such as yoga and regular exercise; equipment modification with heads-up displays during surgery; and training aids for posture correction were shown to be beneficial for MSK-related pain among ophthalmologists. Future studies should strive to improve the certainty of evidence on ergonomics-related interventions for ophthalmologists, which will better support practice and guideline development. Full article

Soft tissue disorders were the most prevalent diagnosis (40.97%). The majority (53.17%) experienced temporary disabilities, and 5.73% had permanent impairments. Key risk factors included inadequate breaks, stressful environments, and limited ergonomic adaptations. This study highlights the critical need for preventative measures, such as ergonomic interventions, adequate rest breaks, and employee education, to mitigate WMSDs. Future research should include ergonomic evaluations and consider broader organizational variables to enhance slaughterhouse occupational health and safety. Addressing these challenges is essential for improving worker welfare and maintaining industry productivity. Full article

Background: Low back pain (LBP) is a common occupational health issue among nurses, significantly affecting quality of life and work productivity. Despite awareness, it remains a major cause of absenteeism and presenteeism, highlighting the need for targeted interventions. This study aimed to assess the prevalence of LBP among Italian nurses and its impact on quality of life and work productivity. Methods: A cross-sectional, multicenter observational study was conducted from May to October 2024 using an online questionnaire distributed to members of the Provincial Orders of Nursing Professions across Italy. The questionnaire included sociodemographic variables and three validated instruments: the Quebec Back Pain Disability Scale (QBPDS), the Oswestry Disability Index (ODI), and the Work Productivity and Activity Impairment Questionnaire (WPAI). Results: A total of 318 nurses participated, with the majority from Southern Italy (57.1%) and female (74.6%). LBP was reported by 57.5% of respondents. Nurses working in Critical Care and those with 30–40 years of experience had significantly higher QBPDS and ODI scores, indicating moderate disability. Nurses working 12 h shifts and those with job restrictions or medical prescriptions reported significantly higher disability levels (ODI > 29, p < 0.001). Nurses on pharmacological therapy reported moderate pain levels, while those engaging in regular physical activity had significantly lower pain symptoms (<20, p < 0.001). The WPAI results showed that 67.0% of nurses reported impaired work productivity due to LBP. Conclusions: LBP is extremely prevalent among Italian nurses, especially affecting physical well-being and, accordingly, the health care quality provided by them. Factors exacerbating this problem are wrong manual handling of loads, not exercising, poor nutrition, and smoking, as well as wrong posture. Fundamental in order to avoid the occurrence of this problem are preventive programs and ergonomic training. Full article

Background: Among the leading causes of work-related disability, musculoskeletal diseases (MSDs) profoundly affect productivity and quality of life. Workplace changes, equipment adjustments, and training courses, among other ergonomic interventions, seek to lower the frequency and degree of MSDs. This systematic review and meta-analysis evaluated whether ergonomic interventions help prevent and control MSDs in various workplace environments. Methods: A systematic search was conducted in PubMed, Scopus, Embase, Web of Science, and Cochrane Library to identify relevant studies. Inclusion criteria included randomized controlled trials (RCTs) that evaluated ergonomic interventions against conventional conditions. Effect sizes were computed using mean differences and pooled using a random-effects model in case of heterogeneity. A uniform Excel sheet was used for data extraction. Revman software (Cochrane Collaboration, Copenhagen, Denmark) was used for statistical analysis. Results: This meta-analysis included 24 RCTs with 4086 workers with different occupations. A meta-analysis of 10 included studies demonstrated lower pain intensity with a mean difference in VAS score between ergonomic interventions and the control group of −0.28 (95%CI: −0.43, −0.14, p = 0.0001). Also, there was a significant reduction in reported MSD-related pain in the lower back with ergonomic interventions with an OR 0.53 (95%CI: 0.40–0.70, p < 0.00001). Moreover, there were statistically significant results for ergonomic interventions in the upper back, ankles, wrists, and neck. In contrast, there were no significant improvements in the thighs, arms, knees, shoulders, and elbows. Conclusions: Our findings support implementing ergonomic strategies as a practical approach to reducing work-related MSDs. However, further research is needed to improve intervention design and long-term effectiveness. Full article

Competitive gaming presents unique musculoskeletal challenges due to prolonged sitting and repetitive hand and arm movements. This study explores gender-specific regional lean body mass (LBM) differences and their associations with musculoskeletal discomfort in competitive gamers. Sixty participants (30 gamers and 30 matched controls; 15 males and 15 females in each group) underwent DXA scans to assess total and regional LBM, handgrip strength tests, and self-reported musculoskeletal pain surveys. Controls were matched for age and BMI and reported comparable academic and screen time but were not engaged in competitive gaming. Male gamers exhibited significantly reduced forearm (p < 0.05) and upper body LBM (p < 0.001), alongside lower grip strength (p < 0.001), compared to controls. Female gamers demonstrated lower upper body LBM (p = 0.01) but showed no significant differences in forearm lean mass or grip strength. In male gamers, negative correlations were observed between forearm LBM and lower back pain (r = −0.59, p < 0.01), highlighting the protective role of regional LBM against discomfort. Extended gaming duration was associated with increased musculoskeletal pain in both sexes (p < 0.05). These findings emphasize the need for targeted ergonomic interventions and physical conditioning programs to address muscle imbalances and reduce injury risk in esports athletes. Future research should focus on longitudinal and interventional designs to optimize musculoskeletal health and performance in this growing population. Full article

Work-related musculoskeletal disorders (WMSDs) are a significant public health concern, particularly in professions requiring prolonged static postures. Objectives: This study examined the influence of demographic and occupational factors on the WMSD prevalence and provides evidence-based recommendations for workplace health improvements. Methods: A cross-sectional study (July–September 2024) surveyed 80 office employees in Varna, Bulgaria, using the Prevent 4 Work (P4Wq) questionnaire. ANOVA and t-tests assessed the WMSD prevalence across demographics, while Pearson’s correlations examined associations with age, BMI, and work experience. Data were analyzed in Jamovi v.2.6 (p < 0.05). Results: The sample (92.5% women, mean age 47.2 years) reported a high WMSD prevalence, with cervical pain (88.8%), lower back pain (83.8%), and shoulder pain (75.0%) being the most common. Work experience, age, and BMI were significantly correlated with WMSD severity, while gender showed no significant associations. Conclusions: WMSDs are highly prevalent among office employees, with lower back, neck, and shoulder pain being the most common complaints. Factors such as higher BMI, longer work experience, and increased workload are associated with greater symptom severity. These results emphasize the urgent need for targeted workplace interventions aimed at reducing ergonomic risks, improving posture, and enhancing employee well-being, ultimately fostering a healthier and more productive work environment.

Musculoskeletal disorders are prevalent among medical professionals like dentists, who often maintain prolonged, ergonomically disadvantageous postures. This study aims to evaluate the feasibility and efficacy of a wearable sensor-based monitoring and feedback system designed to improve posture and evaluate muscle recruitment. Thirty-five healthy adults participated in a controlled experiment, performing a typing task under various postural conditions with and without haptic feedback. Surface electromyography sensors measured muscle activity in the upper trapezius and infraspinatus muscles, while inertial measurement units tracked spine orientation. The results indicated that haptic feedback significantly influenced muscle activity and posture. Feedback reduced deviations from the desired postures but increased muscle activity in certain conditions. Cognitive performance, measured by typing speed, decreased with feedback, suggesting a trade-off between maintaining posture and the performance of the task. These findings highlight the potential of haptic feedback in ergonomic interventions to mitigate MSDs. Future research should explore the long-term effects and optimize feedback mechanisms to balance posture correction and cognitive demands. Full article

Caregiving for dependent older adults presents significant health and occupational challenges, particularly in rural Thailand. This study examines predictors of health-related quality of life (HR-QOL) among in-home caregivers, focusing on health promotion, non-communicable diseases (NCDs) prevention, and occupational health practices. An analytic cross-sectional study was conducted among 701 caregivers across 23 districts in Nakhon Si Thammarat, southern Thailand. Data were collected through structured questionnaires assessing socio-demographics, health behaviors, working conditions, and HR-QOL using the Thai SF-36V2. Stepwise regression analysis identified key predictors of HR-QOL. Our findings indicate that most caregivers were female (81.5%), middle-aged (mean age: 47.7 years), and had moderate education levels. Over half experienced moderate exposure to occupational hazards, including physical, biological, ergonomic, and psychosocial risks, contributing to job strain, inadequate rest, and strained relationships. HR-QOL scores suggested that a significant proportion of caregivers had moderate to poor quality of life, particularly in physical health domains. Stepwise regression analysis showed that better self-reported health promotion behaviors and occupational hazard prevention practices were positively associated with HR-QOL, whereas the presence of NCDs had a negative impact. These findings highlight the need for targeted interventions to enhance caregivers’ well-being and inform public health strategies for strengthening community-based care systems. Full article
