摘要: 上肢肌肉骨骼疼痛與滑鼠使用具有密切相關,滑鼠作業時間愈長,引起上肢肌肉骨骼症狀的機率愈高。高頻率或長時間的滑鼠作業,往往因為累積性傷害病變而出現腕部疼痛之臨床症狀,臨床醫師往往建議患者穿戴腕護具執行例行工作。然而,穿戴腕護具操作滑鼠,有許多操作上之不適感尚待解決。例如腕護具佔據掌心空間,使用者無法握好滑鼠;又如,腕護具包覆腕腹側,減少來自於腕腹側與操作桌面的觸覺備餘回饋,穿戴腕護具操作滑鼠之後,不但減少了觸覺回饋,而且增加本體覺的負擔。因此本研究目的有二:(1)找出腕護具情境下,最適切地滑鼠設計特徵;和(2)探討背側腕護具所提供地觸覺備餘回饋,相較於腹側腕護具,是否可以增進滑鼠作業績效和使用滿意度。本研究透過2 x3(腕護具x滑鼠)重複量測實驗進行腕護具使用者之滑鼠人因特徵分析。腕護具為背側腕護具和腹側腕護具。滑鼠為A、B和C三款滑鼠。本研究同時量測滑鼠操作之作業績效與個人滿意度自覺評比,期望本研究之結果可以滿足使用者在使用效率和滿意度兩方面之使用性需求。本研究結果指出,腕護具之設計特徵和滑鼠之設計特徵兩者間,對於電腦作業績效呈現交互影響。背側腕護具之作業績效顯著高於腹側腕護具。根據結果本研究建議:(1)穿戴腕護具情境下,建議選用之滑鼠設計特稱為:相對高度高且前後比大;(2)若要執行滑鼠操作作業,建議選擇背側腕護具。
Duration of computer mouse use was related to musculoskeletal disorders of arm, elbow, and hand. The two major factors that contributing to mouse-related musculoskeletal disorders of upper limbs was prolonged force applied to the computer mouse and sustained non-neutral postures. Medical clinics often suggest that immobilization using orthoses to promote rest and improve pain. However, computer mouse users who wearing wrist orthoses always feel discomfort to perform computer tasks. They cannot grasp and hold muse easily and cutaneous sensation of volar wrist was absent. The purpose in this study was(1)finding the appropriate mouse design characteristics when wearing wrist orthoses, and (2)finding the appropriate wrist orthoses design characteristics when performing computer mouse task. 2x3 (mouse x wrist orthoses) repeated measured experiments was design to find the appropriate mouse and wrist orthoses design characteristics. The results indicated that task performance was significant interaction between mouse and wrist orthoses. The task performance in dorsal wrist orhtoses was better than volar one when performing computer tmouse ask. In the discussion, the researcher suggest dorsal wrist orhtoses if subject want to performing computer mouse task.
