在工業中，作業人員因工作內容可能需要穿戴手套並使用握力維持握住動作，穿戴手套則會降低手部能力(力量、靈敏度等)，其工作人員必須以更大的手部施力去完成作業，因此往往增加工作人員的負荷，若長期於穿戴不適合之手套的狀況下工作，將會引起肌腱、神經及肌肉傷害，並會增加肌肉骨骼傷害(Musculoskeletal Disorders, MSDs)風險。
本研究利用握力計及肌電訊號量測模組，收集12名男性，於不同手套類型（徒手與穿戴Butyl、Hypalon與Neoprene材質各兩種厚度之手套箱手套）、及不同施力程度（25%、50%、100% 最大自主施力）下，調查握力值、最大維持時間、前臂肌群肌電訊號(Electromyography, EMG)之差異，探討較在不同的施力狀況下，適合選用之手套箱手套。
結果顯示，以握力值而言，施力程度為100%最大自主施力時，手套對握力會有顯著影響，Butyl (0.015inch)手套削弱握力最少而Hypalon (0.030inch)削弱握力最多。在最大維持時間方面，施力程度為25%最大自主施力時，手套對最大維持時間會有顯著性的差異，其時間以Butyl (0.015inch)手套可維持最長時間，而Neoprene (0.030inch)手套之維持時間為最短。本文建議利用手套箱手套工作人員，作業時需要穿戴手套進行手部作業，Butyl (0.015inch)手套為最適合手套。

Industrial workers may need to use gloves and maintain sustained gripping exertions for manual operations. Sustained gripping has been found implicated as a risk factor for fatigue by incremental muscle activity (contraction). Wearing gloves is also known to impair hand performances such as strength, sensitivity, dexterity, etc. Reduced hand performances and fatigue may lead to forceful exertions and awkward hand/wrist postures that have been recognized as risk factors associated with the development of musculoskeletal disorders (MSDs) in the upper extremities.
This study evaluates the effects of glove material (butyl, hypalon, and neoprene in two thicknesses) and level of gripping exertion (25%, 50%, and 100% of the maximum voluntary grip exertion) on maximum endurance time (MET) and forearm muscle activities of four forearm muscles when performing gripping task. Twelve male subjects free of musculoskeletal disorders in the upper extremities were recruited. Grip strength were measured for each subject using a Jamar hand dynamometer with transducer. The BIOPAC MP150 EMG System which includes amplifier & A/D converter and data acquisition software installed in a laptop will be used to collect and process the surface EMG signals.
The results show that the 0.015” butyl glove yielded highest MVC grip strength while the 0.03” hypalon glove yielded the lowest MVC grip strength. For the 25% sustained gripping exertion, the endurance time of the 0.015” butyl glove is the longest while the endurance time of the 0.03” neoprene glove is the shortest. This paper proposed to use the glove box gloves staff, operations need to wear gloves hand job, Butyl (0.015inch) glove is the most suitable gloves.
