Changes in spinal curve during dentistry studies measured with a Spinal Mouse device: A five-year prospective study.

Musculoskeletal disorders (MSDs) often arise and develop during dentistry studies. The most affected regions are related to the spine. Possible associations between spinal curve parameters and MSDs have not yet been investigated amongst dentistry students. This longitudinal observational study aimed to determine whether spinal curve changes during dentistry studies, analyse the relationship between objective findings and subjectively declared MSDs and compare spinal curve parameters with those published in the literature. Seventy-three dentistry students answered a questionnaire on MSDs, and were examined using the Spinal Mouse® device at the beginning, in the middle, and at the end of their 5-year study. The spinal curve exhibited a gender diversity in the lumbar lordosis angle, sacrum inclination, and thoracolumbar ratio. From the first to fifth study year, we observed an increase in the range of motions in the sagittal and frontal planes, an increase in the maximal extent of right lateral inclination, and a decrease in maximal left lateral inclination. Whole-spine backward inclination increased only in women, and forward sacral inclination decreased. No statistically significant relationships were found between the objective findings and subjectively declared MSDs. The spinal curve shape differed between men and women and changed during dentistry studies. No objective markers or predictors of MSDs were found amongst the dentistry students. These findings can serve as a benchmark for further studies on the association between MSDs and objective findings.

Prevalence and Predictors of Musculoskeletal Disorders among Bus Drivers Engaged in Long- Distance Transportation in Port Harcourt, Nigeria

Background An increasing number of occupational injuries occur due to work-related musculoskeletal disorders (WRMSDs) in both developing and industrialized countries. These disorders have an impact on workers' health as well as society at large, posing medical, occupational, and economic challenges.  Objectives This research assessed work-related musculoskeletal disorders and its risk factors among Bus drivers for private long-distance Transport Companies in Port Harcourt, Nigeria.  Materials and Methods This study employed a cross-sectional study design. The multi-stage sampling technique was used to sample 338 long-distance bus drivers in the city of Port Harcourt. Participants' demographic data and information regarding work related musculoskeletal disorders were collected using a modified version of the Standardized Nordic Musculoskeletal Survey questionnaire. Descriptive statistics determined prevalence and inferential statistics was used to determine associated risk factors of WRMSD. The p-value of the test of statistical significance was set at ≤0.05. The participants were all male.  Result 58.6% of the research sample had WRMSDs, according to the findings. After logistic regression analysis, only marital status (AOR=5.714, 95% CI for AOR=3.046- 10.721; p=0.001), prolonged sitting of ≥8 hours, (AOR=0.350; 95% CI for AOR=0.166-0.741; p=0.006) and previous history of pain in a previous occupation (AOR=5.714, 95% CI for AOR=3.046-10.721; p=0.001), were significantly associated with the prevalence of WRMSD.  Conclusion WRMSDs are prevalent in private long-distance bus drivers and are strongly correlated with marrital status, prolonged sitting times (more than eight hours), and a history of muscle or joint discomfort in a prior job.

Predictors of musculoskeletal disorders among special education teachers in Sabah, Malaysia

Special education teachers encounter considerable occupational challenges, yet there is limited information concerning musculoskeletal disorders (MSD) within this group. Therefore, this study aimed to address this gap by determining the prevalence of MSD, investigating associated factors of MSD, and identifying predictors of MSD among special education teachers. A cross-sectional study was conducted among special education teachers in Kota Kinabalu and Penampang, Sabah. Data were collected through self-administered questionnaires and musculoskeletal fitness assessments. Chi-square tests and independent t-tests were utilized to determine factors associated with MSD, while multiple logistic regression was performed to develop a comprehensive predictive model for MSD, which was then validated and tested for model fitness. A total of 122 individuals participated in the study, yielding a response rate of 95 %. The findings revealed a high prevalence of MSD (77.9 %) among special education teachers, with the lower back, shoulder, neck, knee, upper back, and foot being the most affected regions. The multivariable regression model identified several predictors of MSD, including marital status (adjusted odds ratio [aOR] = 4.78, 95 % confidence interval [CI] = 1.49–15.40), body fat percentage (aOR = 1.06, 95 % CI = 1.00–1.12), teaching in prolonged standing for few days a week (aOR = 3.20, 95 % CI = 0.99–10.29) or every day (aOR = 6.20, 95 % CI = 1.44–26.70), mindfulness (aOR = 0.47, 95 % CI = 0.22–0.98), and back extensor strength (aOR = 5.86, 95 % CI = 1.92–17.92). This study highlights the necessity of implementing interventions focusing on the ergonomic, psychological, and musculoskeletal fitness components to mitigate the prevalence of MSD and improve the overall well-being of special education teachers.

Estimating the prevalence and predictors of musculoskeletal disorders in Tanzania: a cross-sectional pilot study.

musculoskeletal (MSK) disorders account for approximately 20% of all years lived with disability worldwide however studies of MSK disorders in Africa are scarce. This pilot study aimed to estimate the community-based prevalence of MSK disorders, identify predictors, and assess the associated disability in a Tanzanian population. a cross-sectional study was conducted in one village in the Kilimanjaro region from March to June 2019. The Gait, Arms, Legs, Spine (GALS) or paediatric GALS (pGALS) examinations were used during household and school visits. Individuals positive in GALS/pGALS screening were assessed by the regional examination of the musculoskeletal system (REMS) and Modified Health Assessment Questionnaire (MHAQ). among the 1,172 individuals enrolled in households, 95 (8.1%, 95% CI: 6.6 - 9.8) showed signs of MSK disorders using the GALS/pGALS examination and 37 (3.2%, 95% CI: 2.2 - 4.3) using the REMS. Among 682 schools enrolled children, seven showed signs of MSK disorders using the GALS/pGALS examination (1.0%, 95% CI: 0.4 - 2.1) and three using the REMS (0.4%, 95% CI: 0.0 - 1.3). In the household-enrolled adult population, female gender and increasing age were associated with GALS and REMS-positive findings. Among GALS-positive adults, increasing age was associated with REMS-positive status and increasing MHAQ score. this Tanzanian study demonstrates a prevalence of MSK disorders and identifies predictors of MSK disorders comparable to those seen globally. These findings can inform the development of rheumatology services and interventions in Tanzania and the design of future investigations of the determinants of MSK disorders, and their impacts on health, livelihoods, and well-being.

Predictors of musculoskeletal disorders and job satisfaction among office workers of an oil company: A cross-sectional study in Iran.

Musculoskeletal disorders are among the significant causes of disabilities and occupational injuries all over the world and can reduce the quality of life and job satisfaction. These disorders prevail among the office workers of the Iranian Oil Company, though research on the involved factors is limited. The present study investigated the incidence and risk factors of musculoskeletal disorders and their association with job satisfaction among the office workers of the Iranian Oil Company. The present research was a cross-sectional descriptive-analytical study on 210 male office workers of the Iranian Oil Company. The prevalence of musculoskeletal disorders and the rate of job satisfaction were measured by Nordic Musculoskeletal and Minnesota job Satisfaction Questionnaires, respectively. The relationship between the variables was analyzed by the SPSS 28 software. The most prevalent musculoskeletal disorders among office workers in the past 12 months were associated with the neck, waist, and knee organs, with 45.70, 41, and 38.10 percentages. Smoking, second jobs, and physical injury histories were identified as three risk factors connected to musculoskeletal disorders (p < 0.05). Forty-one percent of the participants were moderately satisfied with their jobs, and this number was significantly related to musculoskeletal disorders in the shoulders, elbows, back, waist, and knees (p < 0.05). The results of this study indicate that second jobs, smoking, and physical injury histories are three risk factors for musculoskeletal disorders among office workers of the Iranian Oil Company. Thus, it is imperative to identify at-risk office workers and train and encourage them to take preventive actions and employ ergonomic job equipment.

Prevalence and predictors of musculoskeletal disorders (MSDs) among weavers of Varanasi, India: A cross-sectional study

BackgroundWork-related musculoskeletal disorders are widespread among workers in the weaving industry. The most affected body regions are the neck, shoulders, back, and wrist. The present study attempts to understand risk factors for MSDs in various body region among handloom and power loom weavers. MethodA cross-sectional household survey was conducted on a sample of 364 weavers during November 2019 to February 2020. The survey instrument for measuring musculoskeletal symptoms was adopted from a standardised Nordic questionnaire. The impact of the occupation of weaving on MSDs was analysed using binary logistics regression. ResultsThe 12-month prevalence of MSDs was higher among handloom weavers compared to power loom weavers, particularly in the upper back (84-45%), lower back (82–50%), knee (60–35%), and shoulder (76–42%) respectively. Similar patterns were observed in the 12-month prevalence of MSDs, which prevented regular activity inside or outside the home. Analysis suggests that the occupation of weaving raises the risk of MSDs particularly in the shoulder (OR: 4.52, C.I.: 2.63–7.76), lower (OR: 6.9, C.I.: 3.79–12.54) and upper back (OR: 5.63, C.I.: 3.19–9.95). Older age and long years of working are significant risk factors for MSDs. ConclusionsThe findings suggest a relatively higher prevalence of MSDs among handloom weavers, particularly in the upper back, lower back and shoulder, compared to Powerloom weavers. Preventive measures and treatment to minimise the burden of MSDs among handloom weavers are strongly recommended.

Musculoskeletal disorders and risk factors in string musicians

Several workers suffer from musculoskeletal disorders and the situation is even more troubling for musicians, because it is common the musical activity do not be the main source of income. This study evaluated in which extent musculoskeletal disorders and risk factors affect string musicians. Evaluations were performed within groups defined by demographic and behavioural variables. Spearman and Mann-Whitney U tests were applied. A total of 97 string instrumentalists were questioned. Results indicated that bodily regions most affected were upper limbs and column. In turn, inadequate posture represented the element that most cooperated for the arise of musculoskeletal disjunctions. In general, there was no evidence to indicate that predictors of musculoskeletal disorders were similar or divergent among conglomerates. Musicians constantly suffered with complaints in upper limbs occasioned to maintain inappropriate postures during their activities.

Assessment of Risk of Musculoskeletal Disorders among Crane Operators in a Steel Plant: A Data Mining-Based Analysis

Prevalence of musculoskeletal disorders (MSD) among industrial workers is often measured through the Nordic Musculoskeletal Questionnaire (NMQ) survey that captures the MSD complaints across different body parts. The outcomes of such a survey are reported in terms of relative frequency of MSD complaints for the body parts affected and are analyzed through t test, analysis of variance, or logistic regression. The study augments the analysis of NMQ data using relative risk, a statistical measure of prevalence, and classification and regression tree (CART), a data mining–based decision tree. The integrated analysis is done for 76 crane operators of a steel plant in India that considers operators, task, and workplace characteristics as predictors of MSD. The relative risk indices for each of the predictor categories compare the risk of prevalence of MSD. The outcomes of CART-based analysis are objective importance scores that quantify the contributions of the predictors toward the occurrence and severity of MSD. A risk priority index is computed to prioritize the predictor variables with categories in terms of their contribution. The study shows that the lower back and neck and shoulder are the most affected and account for 78.75% of the MSD complaints. CART shows that crane height contributes the maximum for MSD occurrences of both lower back and neck and shoulder. However, for MSD severity, while crane height contributes the most for neck and shoulder, cabin feature (static or movable) contributes the maximum for the lower back.

Computer–telephone interactive tasks: predictors of musculoskeletal disorders according to work analysis and workers’ perception

Sixty-two workers engaged in computer–telephone interactive tasks in an active telemarketing center and a telephone call center of an international bank subsidiary in São Paulo, Brazil, were assessed by means of a work analysis and a self-administered questionnaire aiming to determine the statistical relationship of ergonomic, organizational and psychosocial characteristics of their jobs with the report of symptoms in neck–shoulder and hand–wrist for more than 7 consecutive days and any time away from work during the current job due to musculoskeletal disorders (MSD). According to chi-square univariate tests and multiple logistic regression models, active telemarketing operations, duration in the job and the low level of satisfaction with the physical arrangement of the workstation emerged as the factors most related to neck–shoulder and hand–wrist MSD and MSD-induced time away from work. This study emphasizes the role of psychosocial factors and duration in the job in MSD occurrence and induced absenteeism among workers engaged in computer–telephone interactive tasks.
