Ergonomic assessment of work-related musculoskeletal disorder and its determinants among commercial mini bus drivers and driver assistants (mini bus conductors) in Nigeria

Introduction Work-related musculoskeletal disorder (WMSD) is a leading causes of occupational injury and disability among drivers and workers in the transport industry. This study evaluated the ergonomically assessed WMSD and its determinants among Nigerian commercial mini bus drivers (BD) and mini bus conductors (BC) Method A total of 379 participants (BD = 200, BC = 179) were purposively sampled for this exploratory cross-sectional study. Participants’ WMSD and work related variables were respectively assessed using the standardized Nordic questionnaire and a content-validated, Driving Work Station Assessment (DWSA) form. Data were analyzed descriptively and inferentially using chi-square and logistic regression. The level of significance was set at α = 0.05. Results The participants were aged between 20 and 66 years, with a mean age of 33.26±10.76years (BD = 38.42±10.22years, BC = 27.50±8.13years); most of whom consumed alcohol (84.4%) and experienced severe job stress (73.4%). 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. 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. Conversely, the BD (BD vs BC) had significantly (p<0.05) higher prevalence of low-back (85.0% vs 46.4%), knee (25.0% vs 9.5%), elbow (11.5% vs 3.9%), and wrist (10.5% vs 3.4%) WMSD. There was a significant association between WMSD and each of work duration (X2 = 11.634, p = 0.009), work frequency (X2 = 8.394, p = 0.039), job dissatisfaction (X2 = 10.620, p = 0.001) and job stress (X2 = 16.879, p = 0.001). 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. Conclusion Job stress, work duration and work frequency, posture and fatigue are important determinants of WMSDs among mini bus drivers and their assistants in Nigeria. Ergonomics training intervention for this population is recommended.

Work Related Musculoskeletal Disorder

Background: Modern defence system has a significant role of electrical, electronic and instrument technicians in armed forces. Despite their intensive role, little is known about work-related musculoskeletal disorder in these technicians. Objective: To investigate the prevalence of the work-related musculoskeletal disorder in defence personnel involved in electrical and electronic maintenance and repairs. Methods: A cross-sectional study was carried out for 3 years, in Electrical, telecom and instrument defence technicians (N = 164). Prevalence of work-related musculoskeletal disorder was assessed using the Nordic Musculoskeletal Questionnaire. Effect of age, working hours, work experience, Basal metabolic index and type of job on the prevalence of work-related musculoskeletal disorder was investigated using logistic regression analysis. Results: A total of 119 (72.56%) respondents reported work-related musculoskeletal disorder with 53.04% multiples & 19.51% single work-related musculoskeletal disorder. Simultaneous presence of neck, shoulder and upper back work-related musculoskeletal disorder were observed. Highest rate of work-related musculoskeletal disorder was in neck (44.44%), followed by shoulder (27.16%), ankle/ foot (14.81%), elbow/ forearm (12.96%), low back (11.72%) and wrist/ finger (9.87%). Neck (44%) related work-related musculoskeletal disorder were highest across all job crafts. Work experience (p = 0.012; OR = 0.87; 95% CI – 0.78- 0.97), working hours (p = 0.031; OR= 1.73, 95% CI – 0.58-5.12) smoking (p = 0.00 ; OR = 5.3, 95 % CI = 4.3 – 8.48) and job crafts like electrician (p = 0.434; OR = 1.89, 95% CI = 1.08-3.31) and telecom mechanics (p = 0.026; OR = 1.26, 95% CI =0.74 – 2.15) were significantly associated as risk factors of work-related musculoskeletal disorder. Conclusion: High prevalence of work-related musculoskeletal disorder was observed in electrical, telecommunication & instrument mechanics, with higher multiple work-related musculoskeletal disorder. Working hours, work experience, job craft and smoking were highly associated with a work-related musculoskeletal disorder. We suggest suitable ergonomic intervention and awareness program along with smoking control drive to reduce the risk of work-related musculoskeletal disorder.

Work Related Musculoskeletal Disorder

Context: Since learning guitar and playing it requires repetitive use of muscles, very often with poor posture, guitarists are at an increased risk of nerve or musculoskeletal damage. As playing is the work of musicians, playing-related musculoskeletal disorders (PRMDs) are an appropriate music-specific derivative of work-related musculoskeletal disorder. Since learning guitar and playing it requires repetitive use of muscles, very often with poor posture, guitarists are at an increased risk of musculoskeletal disorder. Aim: To estimate the prevalence of playing related musculoskeletal disorder among non-professional guitar players. Methodology: it was a cross-sectional study done on non-professional guitar players in the age group of 18-30 years. Modified Nordic Questionnaire was used to screen for the symptoms and a self prepared validated questionnaire was used to take the details of playing related activities. Statistical analysis: Results were analyzed using descriptive statistics. Results: The neck and lower back were reported to be most affected with symptoms of pain (29% each) among the selected population, followed by the wrist (17%) and shoulder (15.5%). The main contributing factor was found to be awkward sitting posture and non-use of back support while sitting.

Objective: The key factor for potency of the teeth is their muscular strength. The dominant hand plays an important role in most of the daily muscular activities involving dental procedure. There are many factors, which may affect the grip strength, and very few studies especially in India have shown their correlation with grip strength. Work related musculoskeletal disorders (WRMSD) are an important occupational health problem affecting dental practitioners. This study assessed the prevalence of WRMSD in dental interns in relation to the thumb length and hand grip strength. Material and Methods: Thumb length template, jammer dynamometer, nine-hole peg board, and RULA assessment. Methods: Thumb length was measured by thumb length template. Grip strength was measured by jammer dynamometer, unilateral hand finger dexterity was measured by nine-hole pegboard, and work related musculoskeletal disorder was assessed by RULA. Results: Thumb length was positively correlated with grip strength and work related musculoskeletal disorder. Thumb length was negatively correlated with unilateral hand finger dexterity among dental professionals. Conclusion: Thumb length is a better predictor for measuring hand grip strength and work related musculoskeletal disorder, than unilateral hand finger dexterity.KeywordsDental professional; Hand grip strength; Thumb length; Unilateral hand finger dexterity; Work related musculoskeletal disorder.
