摘要：This study collected 60 Nordic Musculoskeletal Questionnaire (NMQ) data of workers from handmade drinks stores to understand their discomforts on various body sites. The NMQ results indicate that the overall prevalence of musculoskeletal disorders was 88.0% within 1-year. In terms of discomfort, 66.4% of the respondents experienced discomfort at hands/wrists, whereas those at other body sites were less than 42%. The discomfort at hands/wrists was extremely higher than that data collected from other body sites in this study, as well as the different tasks in the previous surveys. Logistic regression result showed that one of the risk factors in hands/wrists discomfort was gender (odds ratio, male:female = 1:3.67). This study further recruited 10 male and 10 female participants to perform the simulated handmade drinks tasks and to measure their wrist postures using a goniometer, under three handmade-drink methods (i.e., upward, curve, and downward shaking). Results showed that, when performing the downward shaking task, females’ wrists revealed more server ulnar deviations (–21.8∘) and radial deviation (15.4∘) on the left and right wrists, respectively, than males’. Contrarily, the male participants adopted a relatively neutral wrist posture (deviations were less than 10∘) during shaking. The findings of this study can be served as references for the prevention from the musculoskeletal disorders resulting from the drinks handmade task, especially for corrective shaking method and employee recruitment.
