人們在選用合適的輔具時，主要目的是希望能促進功能、省力、避免進一步的傷害，在日常生活、工作、休閒時達到更好地參與表現。從復健的角度來看，輔具的介入同樣被視為是很重要的治療項目之一。而國內設有輔具補助相關辦法中，內容多在專業人員對於患者的生理功能評估、購買建議，以及進行追蹤輔具在購買後廠商的售後服務和使用說明，較少了解使用者的需求和主客觀感受。
本研究以人因的角度評估，比較兩種不同的輔具在進行手工具操作以及握力測試，模擬工作狀態的表現。讓使用者穿戴市售、客製化豎腕副木，目的在於分析兩種不同方式的副木滿意度、主客觀舒適度。收集20位右手慣用的成年人，研究人員第一步為受試者的慣用手製作客製化豎腕副木，以及選擇合適尺寸的市售豎腕副木後，先後安裝壓力感測片在市售、客製化豎腕副木與皮膚的接觸面，第二步請受試者戴上市售、客製化豎腕副木進行最大握力施測以及手工具操作測驗，完成工作任務後填寫台灣版魁北克輔具使用者滿意度評量(QUEST-T)、舒適度主觀評分表，總共耗時約一小時。
實驗結果在主觀感受方面發現在受試者對於客製化豎腕副木有較高的滿意度且具有顯著差異，且對於輔具以及輔具服務都是具有顯著差異，而主觀舒適度在手部區域分數也顯示在手掌的掌指關節和手臂前臂這兩個區域有顯著差異，客製化豎腕副木高於支撐型固定護腕，在手工具等工作任務表現上穿戴客製化豎腕副木有較好的工作表現。本研究也發現在執行各種工作任務時有不同區域的壓力承重，在主客觀相關性分析方面，滿意度與客觀壓力數值和工作任務表現皆沒有顯著相關，主觀舒適度與客觀壓力參數在兩種輔具上有不同的相關性。期待未來也可以從人因的評估與壓力分析進行實驗因子的相互比較，提供未來建立輔具服務的量化評估方式，從輔具使用者為中心提升輔具服務的成效以及品質。

The assistive device aims to promote functions, save efforts, avoid further secondary hurt, and better participation in daily life, work, and leisure. From the point of view in rehabilitation processing, assistive devices’ intervention is regarded as a critical rehabilitation treatment project. There are related measures for assistive technology in Taiwan, the content is mostly in the physical functional status of the patients with disabilities, purchase suggestions, and follow the after-sales service and instructions for use, much less the user's needs, subjective and objective feelings. This study aims to analyze the users’ experience in hand tools while using the hand devices, the subjective and objective comparison of satisfaction and comfort.
This study evaluated human factors and the performance of working conditions by comparing two different aids in hand tooling and grip strength testing. The users were instructed to wear a composite orthosis and custom-made cock-up splint separately. The purpose was to analyze the two different ways of cock-up splint’s satisfaction, subjective and objective comfort, and to evaluate the weight and length of the two hand accessories.
Twenty healthy right-handed participants were recruited in the experiment. The first step was to prepare custom-made wrist splint for the participant’s right hand and to select the appropriate size of the composite orthosis. In the composite and custom-made orthosis contact surface of the wrist and the skin, the second step was to evaluate the maximum grip strength and the hand tools operation test. After the hand tools operating working test, the participants filled in the Taiwan version of Quebec accessory user satisfaction evaluation (QUEST-T), a comfortable subjective score sheet, which took about one hour.
In terms of subjective feelings, the results found that the subjects had high satisfaction and significant differences in custom-made cock-up splint. And there were significant differences in the items of assistive devices and assistive services. The regional scores also show that there are significant differences between the metacarpophalangeal joints of the palm and the forearm of the arm. The custom-made cock-up splint is higher than the composite orthosis. When the user worn the custom-made cock-up, using hand tools had better task performance. We also found that there are different areas of pressure when performing various work tasks. In the subjective and objective correlation analysis, satisfaction is not significantly related to objective pressure values and task performance. There were different correlations between comfort and each area of the pressure of hand when wearing the two assistive devices.
Looking forward to the future, the experimental factors from the human factor assessment and the pressure analysis would take into consideration to provide a quantitative evaluation method for the future establishment of the service, and improve the effectiveness and quality of the assistive technology service in the center of users.
