探討在嚴肅遊戲中線驅動力對於手腕之影響

Abstract

腕隧道症候群是一種常見的手腕累積性運動傷害，約有五成是源自於職業性傷害，手腕肌肉的復健是腕隧道症候群復健的方法之一。本研究的目的是針對腕隧道症候群，透過嚴肅遊戲結合穿戴式裝置，達成一種有趣且能省力與提升表現的復健訓練。本研究設計了一款方塊放置嚴肅遊戲以及配合的穿戴式裝置；遊戲部分玩家須將方塊放置於盤中，往復此動作，成功次數越多則分數越高；裝置部分包含硬體的線驅動手腕穿戴式裝置，以及控制馬達、讀取感測器資料以及電腦訊號溝通的微機電控制器。實驗進行了前導人體實驗以及主要人體實驗，前導人體實驗是為了瞭解日常生活活動中手腕的運動範圍，而主要人體實驗則是測驗裝置與嚴肅遊戲的效能。數據分析通過切分循環以及濾波肌電訊號觀察每次運動循環的手腕角度、角速度以及肌電訊號的變化。前導人體實驗的結果表明，大部分的日常生活活動會用到橈側/尺側偏斜或是投擲運動，投擲運動是橈側/尺側偏斜以及屈曲/伸展的綜合運動，因此設計上選用橈側/尺側偏斜的嚴肅遊戲設計。主要人體實驗的結果表明裝置無法提供使用者助力，甚至會在延遲時產生阻力，但裝置能提升使用者在嚴肅遊戲中的表現，即分數更高。本研究未來期望能輕量化、提升輔助能力、結合機器學習以即建立資料庫的方向研究。

Carpal tunnel syndrome is a common wrist injury, with about 50% originating from occupational hazards. Wrist muscle rehabilitation is one method of treatment. This study aims to create an engaging and efficient rehabilitation training method for carpal tunnel syndrome by combining serious games with wearable devices. We designed a block-placing serious game and a corresponding wearable device. In the game, players place blocks in a tray, scoring points based on successful placements. The device includes a wrist wearable with a microelectromechanical controller to manage motors, read sensor data, and communicate with a computer. Experiments included a preliminary and a main human study. The preliminary study assessed wrist movement range in daily activities, while the main study tested the device and game performance. Data analysis observed wrist angle, angular velocity, and EMG signal changes during movement cycles. Preliminary results showed most daily activities involve radial/ulnar deviation or throwing motions, leading to a game design based on these movements. Main experiment results indicated the device did not assist users and sometimes provided resistance during delays. However, it enhanced performance in the game, resulting in higher scores. Future research will focus on making the device lighter, improving assistive capabilities, and integrating machine learning for database development.
