![]() (2021) Ergonomic assessment of work-related musculoskeletal disorder and its determinants among commercial mini bus drivers and driver assistants (mini bus conductors) in Nigeria. Working beyond 4days/week (OR = 10.019, p = 0.001), job dissatisfaction (OR = 1.990, p = 0.031), constrained working postures (OR = 5.324, p = 0.003) and fatigue (OR = 4.719, p = 0.002) were the predictors of WMSD.Ĭitation: Ekechukwu END, Useh E, Nna OL, Ekechukwu NI, Obi ON, Aguwa EN, et al. The BC (BC vs BD) had significantly (p<0.05) higher prevalence of Neck (47.7% vs 21.5%) and upper back (80.4% vs 30.5%) WMSDs. There was a high prevalence (95.8% BD = 94.5%, BC = 97.8%) of WMSDs, the lower back (66.8%) and upper back (54.1%) had the highest regional prevalence of WMSD. Additionally, with aging, the likelihood of experiencing discomfort in the neck, upper back, and knees is increased.The participants were aged between 20 and 66 years, with a mean age of 33.26☑0.76years (BD = 38.42☑0.22years, BC = 27.50☘.13years) most of whom consumed alcohol (84.4%) and experienced severe job stress (73.4%). Moreover, seat comfort was found to be highly correlated with discomfort in the neck, shoulder, and upper back areas. CONCLUSION: Fifty-seven percent of the drivers were suffering from discomfort in their lower back region. Additionally, 19 equations, their correlations, and their odds ratios (ORs) were formulated with a Nagelkerke R2 value greater than 0.05. ![]() This relationship was not statistically significant in the lower back area (p = 0.300). RESULTS: Results demonstrate that hours of exposure to vibration were associated with discomfort in the neck and shoulders (p < 0.001). While hypothesis testing was used to assess the association of different factors in musculoskeletal discomfort, logistic regression was applied to explore different correlations among questions of the survey. A total of 384 participants were interviewed by an updated version of the Nordic musculoskeletal questionnaire (NMQ). MATERIALS AND METHODS: A cross-sectional study design was applied. PURPOSE: This study aims to investigate the correlation between different factors of musculoskeletal discomfort in heavy truck drivers. Heavy truck drivers are exposed to various psychological, psychosocial, and physiological factors, some of which can cause musculoskeletal discomfort in different body regions. Ergonomic intervention measures with workplace health promotion activities need to be implemented in order to reduce the risk of WMSDs among bus drivers. Prospective studies are necessary to confirm the cause and effect in this association. ![]() Exposure to unsafe ergonomic practices/conditions and health risks were evident from the findings of the study. Conclusion: The current study evaluated the risks of developing WMSDs among bus drivers. From NMQ, it was found that 26% of drivers had musculoskeletal problems in the neck, 24% in the back, 20% in the upper limbs (shoulder and wrists were equally affected), 6% in the knees and 4% in the ankles. Among others, 29% were at moderate risk and 14% were at low risk, whereas 11% were at very high risk, requiring immediate change. As per RULA, 46% of bus drivers needed further ergonomic investigation and modification of workstation/work style, indicating that the risk for WMSDs is potentially high. ![]() REBA revealed that nearly half (46%) of the drivers were at high risk of developing WMSDs, whereas14% were at very high risk and 29% were at medium risk. Results: The results of QEC showed that back and shoulder had very high exposure followed by neck and wrist. Then the exposure and risks of developing WMSDS were assessed using Quick Exposure Check (QEC), Rapid Entire Body Assessment (REBA), Rapid Upper Limb Assessment (RULA) and Nordic Musculoskeletal Questionnaire (NMQ). Methodology: A total of 280 male drivers with acute body pain in any region were randomly selected for the study, and ergonomic information on driver’s seat was collected using a validated questionnaire. This study assesses ergonomic exposure on the developmental risk of WMSDs among bus drivers. Professional drivers are particularly at high risk for developing back pain and neck pain from prolonged sitting and vehicular vibration. Background: Work-related musculoskeletal disorders (WMSDs), especially low back pain and neck pain cause substantial socio-economic losses.
