摘要

國外有不少的文獻、論文及新聞報導玩Nintendo Wii 造成肌肉及骨骼傷害，但卻無研究探討Wii Remote在設計上是否有問題。
在本研究中，我們針對電玩控制器(Wii Remote)的重量特徵作出探討，討論在不同重量的電玩控制器(100克、140克、180克、220克以及260克)在相同模擬網球揮拍頻率之下，上肢肌肉的肌肉負荷。因此利用表面肌電儀(Surface Electromyography,sEMG)以及電子量角器量測使用者操作不同重量(100克、140克、180克、220克、260克)電玩控製器時手部肌肉(尺側伸腕肌、伸指肌、尺側屈腕肌、前支三角肌、中段三角肌、後支三角肌和斜方肌)的負荷，並以定性及定量的分析方法，探討所量得的資料，從而選出最佳的重量。
研究結果表示經常使用過輕或是過重的電玩控制器，會造成手臂肌肉的不適。且不同重量的電玩控制器在相同模擬網球揮拍頻率之下有著不同肌電訊號。25個受測者在實驗使用著不同重量的電玩控制器，模擬打網球動作揮拍電腦螢幕中設計之網球遊戲的球。在相同頻率之下，使用140G的電玩控制器較不易造成手部及肩部肌肉(尺側伸腕肌、前支三角肌和斜方肌)的負荷。研究結果亦顯示手臂揮動之角速度及角加速度會影響肌肉的活動值。

Frequently using underweight or overweight video game controllers may lead to musculoskeletal discomfort and symptoms in forearms, upper arms and shoulders. Differently weighted controller being played at the same frequency may have varied effects on forearm, upper arm, and shoulder muscle activity. Each of the twenty-five subjects repetitively performed the task of simulating playing tennis with each of the five different weight controller at the same frequency on video game. The extensor carpi ulnaris, extensor digitorum, flexor carpi ulnaris, anterior deltoid, middle deltoid, posterior deltoid and upper trapezius muscle activity were recorded by surface electromyography and the right shoulder postures were registered by an electrogoniometer, and then the recorded data were analyzed by the one-way ANOVA. The lowest ECU, ED, FCU, AD, MD, PD, and Trap muscle activity all occurred in using the controller 140G. To play at a preset waving frequency, selecting and using a corresponding optimally weighted controller could provide users more neutral arm postures to reduce the forearm, upper arm and shoulder muscle activity and the risk of musculoskeletal disorders.
