論文中文摘要:肌肉骨骼傷害(work-related musculoskeletal disorder, WMSD)是造成工作能力和生產力降低的一個首要原因。而這類型疾病是由於重複性的動作、較高施力、或不良姿勢所引起。過去有研究指出清潔人員是罹患肌肉骨骼傷害的高風險族群,但對於清潔人員相關的研究以水平面作業較多,針對立面清潔作業所進行的研究相對較少。因此本研究使用影機投射疊加畫面至4塊WiiFit,做為受試者進行實驗過程中的視覺回饋,並且調整WiiFit位置以模擬3種不同離地高度的立面(L:0~51 cm, M:80~131 cm, H:170~221 cm),讓受試者使用抹布以及長柄工具分別對3個高度的WiiFit表面進行模擬清潔作業。實驗過程中電腦持續收集WiiFit系統經藍牙所傳送的力量及施力中心資料,將施力大小以顏色疊加方式透過投影機投射於WiiFit表面,即時地提供參與者視覺回饋。實驗最初設定投影所有WiiFit板面為灰色,受力的位置隨施力的大小及時間逐漸變白,當全部區域達到設定的施力程度時,該WiiFit板面投影顏色便轉為綠色。
實驗蒐集30名受試者(男、女各半)作業過程之WiiFit受力、心率、EMG(伸腕、三頭、三角、斜方肌)、主觀負荷、與偏好工具。實驗結果顯示在作業高度H下,大多受試者(76.7%)偏好使用長柄工具;使用抹布時三頭肌、三角肌、斜方肌的肌電訊號是所有作業組合中EMG值最大的,其50%ile平均肌電強度皆超過30%MVC。相較之下,在高度M下使用抹布作業的負荷最低,受到70%受試者的喜好。然而在作業高度L時,可能因使用抹布或長柄工具時皆需要付出額外成本(蹲姿、彎腰不良姿勢或增加施力),因此沒有明確偏好的工具。
論文英文摘要:Work-related musculoskeletal disorder is one of the leading causes of loss in work ability and productivity. This type of diseases are mostly caused by repetitive movement, high force exertion, or poor working posture. Previous studies have shown that cleaners are high risk groups with musculoskeletal injuries. However, most studies have been focused on cleaning horizontal surfaces, such as floors, and relatively few studies have been focused on cleaning vertical walls or windows. Therefore, this study use a projector to project superimposed images onto surfaces of 4 WiiFit balance boards as visual feedback for subjects while performing the experiment. The WiiFit board position was adjusted to simulate three different erect surface elevations (L:0~51 cm, M:80~131 cm, H:170~221 cm). Subjects were asked to use a rag and a long-handle tool to simulate cleaning operations on the board surfaces of 3 different heights, respectively. The WiiFit boards continuously measured exertion forces and center of resultant force of each participant, sending the measured data to a computer via Bluetooth. The computer then controlled the projector to project color image onto the board surfaces to provide visual feedback. The images, originally grey, turned whiter as the computer program continuously read in data and translated force magnitude into color depth and superimposed its “magnitude” onto the corresponding board location. The images finally turned green when the entire region reached the force setting level.
The experimental data collected from 30 subjects (15 male and 15 female) included WiiFit board force, heart rate, EMG(extensor digitorum communi, triceps, deltoid, and trapezius), subjective workload, and tool preference. The results showed that most subjects (76.7%) preferred to use a long-handled tool at working height H. When using a rag, the subjects’ dominant hand triceps, deltoid and trapezius muscle EMG intensities at the working height H are the largest of all assignments, each muscle with an average 50%ile EMG intensity exceeding 30%MVC. In contrast, the lowest workload occurred at working height M with 70% subjects preferring to use a rag. It is difficult to tell subjects’ preference of tool use at working height L. It is likely because additional costs must be paid to poor postures or increasing forces either for a rag use or a long-handle tool use at working height L.
