背景與目的：虛擬實境（virtual reality)是近年來快速發展的多媒體互動技術，具有模擬多種視覺 環境並提供多元感覺回饋的特色。巴金森（Parkinson’s disease)患者在動作起始與動作學習的過程 中較健康成人更依賴感覺提示•因此虛擬實境可適用於巴金森患者的訓練。方法與結果：本文回 顧過去探討虚擬實境應用於巴金森患者平衡訓練的文獻，發現虛擬實境平衡訓練的療程設計1在 頻率與時數上大致與常規平衡訓練（conventional balance training)類似’同時也依循動作學習理論 中任務導向（task orientated)' 變異練習（variable practice)與隨機練習（random practice )的原則。 結論與臨床應用：目前研究實證顯示虛擬實境平衡訓練在改善平衡與行走表現上與常規平衡訓練 有相似的效益，而在感覺整合（sensory integration)上虛擬實境似乎與常規平衡訓練具不同的效果。

Background and purpose: Virtual reality (VR) is a fast-growing technology of interactive multimedia in the past decade, with the capability to simulate different visual environments and provide various sensory feedbacks. People with Parkinson^ disease show greater dependence on sensory cues for movement initiation and motor learning than healthy adults, therefore VR could be an ideal tool for balance training. Methods and Results: This article reviewed literatures addressing the application of VR balance training in people with Parkinson^ disease. We found that VR balance training and conventional balance training usually have similar training frequency and training time. In addition, VR employs the motor learning principles including task-orientated training, variable practice and random practice. Conclusion: Current evidence suggests that VR and conventional balance training have comparable effects in improving balance and walking perfomance, despite VR and conventional balance training demonstrate different effects in sensory integration.
