Abstract
背景:肢體功能控制對日常生活扮演重要角色。意外及老化產生的活動衰弱,可能明顯影響肢體動作與功能能力。需要量化評估工具進行察覺紀錄,目前穿戴式裝置可提供量化數據並對於驗證穿戴式裝置用於量測關節活動角度的信效度研究不多,可能影響醫療人員於臨床上使用該穿戴式系統的意願。
目的:驗證穿戴式慣性感知系統裝置對肢體動作關節角度數據量測之效度、再測信度。
方法:研究設計為方便取樣,以口頭方式招募50位健康受測者參與本研究信效度試驗。運用臨床評估關節活動度所使用量角器,比較穿戴式慣性感知器量測所量得的肘關節,肩關節,髖關節,膝關節角度數據,進行效度測試之後以相同測試間隔14天之再測信度量測。統計分析以單一樣本 t 檢定 (one-sample t-test) 用於驗證系統量測角度數值與量角器之間的角度量測同時效度(concurrent validity);以組內相關係數ICC3,1分析,用於驗證系統量測關節度之再測信度(test-retest reliability);以95% 信賴區間Bland-Altman分析慣性感知系統與量角器量測關節角度之一致性。
結果:穿戴式慣性感知系統相較於量角器在分析結果整體上量角器與慣性感知系統關節角度P > 0.05表示無差異,除了肩關節彎曲的量角器與慣性感知系統關節角度P < 0.05表示有差異,顯示高度同時效度。再測信度驗證Intraclass correlation coefficient (ICC3,1) 組內相關係數ICC3,1介於0.974到1.000,呈現高度正相關。顯示慣性感知系統關節角度表現具有高度可靠性與準確性。
結論:本研究中使用的慣性感知系統應用於健康年輕人量測肢體關節活動方面,呈現良好信度與效度表現,縱使肩關節彎曲及髖關節彎曲角度有偏差仍在隨機誤差可接受範圍內,表示慣性感知系統具有良好穩定性與可精準量測肢體動作與活動功能。
