Cognitive Ergonomics Training, Awareness of Safe Work Practices, Among Street Sweepers


The aimed was to evaluate the effect of the cognitive ergonomics training to increase awareness of safe work practices among street sweepers on musculoskeletal discomfort. This quasi-experimental study was conducted among 68 voluntary street sweepers who were having musculoskeletal discomfort score ≥ 4 in Chiang Rai province, Thailand (intervention, n=34; control, n=34). Face to face interviewed were used musculoskeletal discomfort and awareness of safe work practice questionnaire. Rapid Entire Body Assessment (REBA) measured to assess the body posture for movement, action, coupling and repetition. Musculoskeletal discomfort score was investigated by Physiotherapist. Data analysis included descriptive statistics, Chi-square test, Independent T-test, and repeated measure ANOVA. No difference of awareness score between the intervention and the control group. The mean score of the awareness of cognitive ergonomics training showed the difference from exit model, 1st , 2nd , 3rd, and 4th follow-up with statistical significance at p<.001. The finding suggested that the cognitive ergonomics training was appropriated to increase awareness safe work practice, prevent muscle injury and soreness that associated with repetitive movement and awkward posture in street sweepers.
