本研究針對長時間固定姿勢造成肌肉骨骼不適之電腦族群，探討電腦使用中肩部動作形態，提出肩關節保健運動之建議。並運用明箱設計程序發展肩部保健運動產品，達成幫助活動肩關節運動之目的，減少電腦因長期使用所造成的上肢肌肉骨骼傷害。

研究分為三階段：〈1〉電腦使用者肩關節動作形態分析。實驗由20位電腦使用者操作電腦輸入設備，並以攝影觀察(Video-Based Observation)記錄受測者於電腦工作中上肢肩關節活動之動作。運用聚類分析法(Clustering Methods)歸併操作動作之肩關節施力屬性，以瞭解電腦工作活動之肩關節向度及缺少運動之向度，作為提出建議運動準則。〈2〉肩部保健產品設計。運用目標決策樹(Object Tree)將目標轉換層屬架構，發展加強活動之運動產品。層次分析(Analytical Hierarchical Process；AHP)計算各設計要素之權重，瞭解構面要素重要性順序，以利針對重點發展構想並以概念選擇法(PUGH)評估可能方案。〈3〉產品實驗評估與驗證。以效度實驗及主觀滿意度問卷進行產品驗證。

實驗結果將電腦使用動作分為：〈1〉肩胛面上舉抬高〈2〉肩胛面上舉偏前屈〈3〉肩胛面上舉偏外展。電腦使用動作中，肩關節活動向度「內旋外旋(Internal Rotation and External Rotation)」、「後伸(Backward Extension)」、「內收(Adduction)」、「水平後伸(Horizontal Extension)」完全沒有作動的。「前屈(Forward Flexion)」0˚~18.5˚、96.5˚~180˚、「外展(Abduction)」0˚~21.5˚、94.5˚~180˚、「水平前屈(Horizontal Flexion)」0˚~30.5˚、63.25~180˚為不活動角度。而設計產出之肩部保健產品-「彈性運動帶」交由受測者使用訓練，量測其使用前後之肩關節活動角度。「前屈」、「後伸」、「內旋」、「水平後伸」使用訓練前後之肩關節活動角度差異最為明顯(F(2,60)=4.98, P<0.01)。主觀滿意度問卷中，受測者對產品「操作」評價最高(平均數7.37)，「外觀」較低(平均數6.68)。透過色彩計劃改善，亦或後續繼續研發相關產品。

The research aimed at computer operation that caused musculoskeletal discomfort in long-tern fixed posture. This study will provide suggestion about shoulder healthy care for shoulder movement. Moreover, to apply glass box of design method to develop shoulder healthy care product arrived at purpose for help of shoulder healthy care and this will be trying to reduce injury of musculoskeletal.

This research include three stages:
1. To analyze for shoulder movement of computer operation. The experiment consists of twenty users to operate input equipment. Also, according to the video-based observation to take down the motion of shoulder joint. By applying clustering methods, we would like to conclude the relationship between users shoulder joint and their computer working- environment. Understanding fully about shoulder healthy care, it would be able to make recommendation.2. Shoulder healthy care product design. Appling Object Tree to change frame of levels to develop product for Shoulder healthy care. Using Analytical Hierarchical Process〈AHP〉to get specific gravity of design factor and developing the concept with PUGH to evaluate proposal for feasible.3. Evaluation of experiment and verify for product. Using effectiveness experimentation and questionnaire survey of subjective to verify for product.

The results of experiment for computer operating posture could be divided into: 1. Scapular plan elevation 2. Scapular plan elevation and forward flexion 3. Scapular plan elevation and abduction. There is no motion in processing of computer operating of shoulder joint activity for Internal rotation and external rotation, backward extension, adduction, horizontal extension. Also non motion angles for forward Flexion 0˚~18.5˚、96.5˚~180˚, Abduction 0˚~21.5˚、94.5˚~180˚, Horizontal Flexion 0˚~30.5˚、63.25~180˚. The shoulder healthy care product〈stretch band〉trained subject to measure motion angles of shoulder movement. It was quite obvious (F(2,60)=4.98, P<0.01) that the motion angles of shoulder movement has difference between before use and after use. In questionnaire survey of subjective, the subject has most high score of evaluation (average 7.37) for operation and has less score for appearance (average 6.68). Finally we pass through color scheme to improve the research for interrelated product.
