研究背景:全球人口老化的現象明顯，其老年人的健康生活逐漸成為世界各國重視的議題之一。隨著年紀的增加，身體機能會逐漸退化，半規管內毛細胞以及前庭神經元的數目的減少，引起前庭系統的功能缺失，伴隨出現眩暈、不穩、身體姿勢平衡較差。臨床上前庭系統的評估及復健方式皆有其不足之處，探討健康組群與眩暈患者在身體平衡參數上的差異以及客製化的前庭復健復健系統有其必要性。目的：（一）為針對眩暈的老年者，發展功能性身體穩定的評估系統，(二)開發以生活實境訓練為主的前庭動眼復健系統，(三)比較健康組群與眩暈患者在不同評估動作的身體穩定表現。方法：評估系統方面為收集兩組受試者（14位）：健康年輕族群7位，及前庭功能低下患者7位，請受試者完成原地左轉、原地右轉、踏步、踏步及轉頭四個動作，透過測力板去擷取身體的壓力中心的位移訊號，分析出身體晃動角度、身體壓力中心的移動軌跡長。復健系統方面：應用National Instruments LabVIEW程式開發軟體撰寫，復健訓練模組搭配生活實境的圖片，將復健成效轉移至生活中。資料分析：健康族群與眩暈患者的參數差異度以百分差值作為分析。結果：在不同評估動作中，眩暈患者的身體中心移動軌跡長、動作完成後的身體晃動角度均大於健康組群。結論：眩暈患者的身體平衡皆較健康年輕人差，且在不同評估動作中，眩暈患者表現較健康年輕人差。

Background：As the percentage of elderly increases in our population, health issues related to aging become important topics. It is believed that aging cause deterioration of the vestibular system and lower postural stability. The hypofunction of the vestibular system causes dizziness, imbalance, and de-equilibrium. However the assessments of vestibular dysfunction had some limitations and the rehabilitation approach did not meet clinical needs. Purposes: Purposes of the study were (1) To develop a computerized evaluation system for assessing functional body equilibrium. (2) To develop a computerized rehabilitation training system with visual input representing daily life environment. (3) Compare the stability between health adults and patients with vestibular hypofunction. Methods: For the evaluation system, 7 healthy young adults and 7 patients with vestibular hypofunction were studied. Subjects were asked to make a circle to the right and left, step, and head rotation combined with stepping. Postural sway was measured by force plate while subjects did all activities described above. Our rehabilitation training system consists 2 large computer screens and a force plate, and it was controlled by customized LabVIEW software. Exercise protocol were based on movement in our daily life. Data Analysis: Percentage difference were used to compare the health control and patients with vestibular hypofunction. Results: The sway angles after the movements and total excursion in vestibular hypofunction patients were all greater than young adults. Conclusion: Our computerized system combines two subsystems, one can evaluate patients functional body equilibrium, and the other subsystem can train patients’ balance. Based on the results, equilibrium among vestibular hypofunction patients is weaker than healthy adults.
