| Popis: | 98 Cleaners are one of the high-risk groups of musculoskeletal disorders. Due to the lack of research on musculoskeletal problems in cleaners in Taiwan and the fact that most previous studies were usually carried out through questionnaire surveys only, this study is aimed to, by using questionnaires and instrumental measurements, investigate the musculoskeletal disorders among cleaners in Taiwan. 180 cleaners were approached to complete the Nordic Musculoskeletal Questionnaire (NMQ). Several volunteers were randomly selected to measure the angle changes in wrist and elbow and potential of the nerves or muscles, by using Electro-goniometry and Electromyography (EMG), while performing sweeping, electrostatic sweeping and mopping. The top four body parts with the highest prevalence of musculoskeletal discomfort are hands/wrists (41.7%), shoulders (41.1%), lower back/waist (37.8%), and elbows (33.3%). The majority (67.9%) of the symptom is sore and pain of the body parts. While cleaners performing different tasks, the results indicated that mopping has significantly the highest wrist repetitiveness. And their wrist flexion/extension angles were greater than the tailors’. 15.2% of cleaners’ muscular load monitoring during measurement are more than 15% MVC that recommended by OSHA. Cleaners’ severe pain showed strong associations with colleague cooperation, working time pressure, monotony of work, and job satisfaction. It’s suggested that ergonomic design of cleaning tools, increase breaking time, and training cleaning skills. Development of those strategies in cleaning work can significantly contribute to the reduction of physical and psychosocial stressors which will in turn improve the well-being and health of cleaners. |
