| dc.description.abstract | 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.
