Initial assessment of musculoskeletal disorders and ergonomics risk factors among laboratory workers, Kuala Lumpur

BackgroundMusculoskeletal disorders (MSD) are work-related injuries that can impact the movement or function of the human body's musculoskeletal system.ObjectiveThis study aims to assess musculoskeletal disorders and ergonomic risk factors (awkward posture and repetitive motions) among laboratory workers.Methods49 laboratory workers were assessed in this cross-sectional study. MSD prevalence was evaluated using the Cornell Musculoskeletal Discomfort Questionnaire (CMDQ). Awkward posture was assessed with the Rapid Upper Limb Assessment (RULA) approach, and repetitive motion was evaluated using the Assessment of Repetitive Tasks (ART) Tools. The data was analysed using SPSS Version 26.0.ResultsMSDs were most prevalent in the neck (91.8%), followed by the left shoulder (87.5%), right shoulder (85.7%), and lower back (85.7%) in the past week. The level of ergonomic risk for awkward posture is high risk (RULA score = 7), although most repetitive motion tasks indicate low risk (ART score <11). There is a significant correlation between the frequency of MSD and risk factors such age, gender, and shift employment.ConclusionsIt is recommended to implement ergonomic approaches, such as modifying workstations to promote good body postures during jobs, to decrease the likelihood of musculoskeletal problems among laboratory workers.
