Abstract:	週邊前庭神經病變所引起的眩暈會造成重心失衡，進而影響日常生活的品質，雖然可以藉由外科手術或前庭神經抑制藥物減緩眩暈症狀，但是此類藥物多有副作用，所幸前庭功能復健運動已被認為可以有效改善眩暈症狀。但是，復健過程由於過於單調，缺乏具有挑戰性且可調適(adaptive)的訓練內容，同時缺乏以運動分析為基礎的評估方法，以至於降低了復健運動的復健成效。本研究運用虛擬實境技術，包括立體影像技術、互動技術以及動畫遊戲技術，根據臨床所使用之Cawthorne-Cooksey前庭復健訓練運動，開發新型互動式復健訓練系統，同時也運用感測器技術以及運動分析技術，開發了平衡度評估系統。本研究進行了臨床試驗(32 subjects, 6 training sessions)，於實驗過程中，完整的量測並記錄病人的任務表現資料、重心偏移分佈之歷時資料以及主觀感受之問卷資料。實驗結果經由任務表現評估以及平衡度分析，顯示本系統對於協助病人進行眩暈復健訓練具有顯著性療效，此外根據分析各項任務表現，初步檢驗復健項目對病人的克服難易度，臨床問卷的回饋也顯示病人具有更高的意願與動機使用此一新穎的系統進行復健。Dizziness caused by the peripheral vestibular nerve disease may lead to imbalance of the center of gravity, affecting quality of daily life. Fortunately, vestibular function rehabilitation exercise is thought to be able to effectively reduce the symptom of dizziness. However, since rehabilitation process may be bored for patients, lacking of task challenges, adaptive training contents, and assessment method based on exercise analysis, the effectiveness of rehabilitation exercise is thus reduced. In this research, virtual reality technology was applied, involving stereo image technology, interactive technology, and animation game technology. A new interactive rehabilitation training system was developed based on the Cawthorne-Cooksey vestibular rehabilitation exercise which is commonly used in the clinical. The sensor technology and exercise analysis technology was used to develop evaluation system for testing the level of balance. Thirty-two subjects were asked to perform 6 training sessions for the clinical test. During the experimental process, the task performance data, the historical data of the deviation distribution of center of gravity, and the subjective feeling questionnaire survey data of the patient was completely measured and recorded. Through the task performance evaluation and the analysis of level of balance, the experimental result has proved the medical effect of this system in assisting the patients to perform dizziness rehabilitation training. According to performance of each task, the difficult level was verified and applied based on the individual capability. The clinical observation also shows that the patients have higher willingness and motivation to use such new system to perform rehabilitation.
