Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
This study aims to investigate the effect of computerized vestibular function assessment and interactive training system, combined with cognitive/motor dual-task for the elderly with dizziness. Drawing from previous clinical rehabilitation experiences, a method for assessing vestibular function and balance performance will be designed to compare the movement differences among older adults with different cognitive performances. Subsequently, through scientific and objective motion capture analysis, a comprehensive assessment module will be established to evaluate the dual-task performance of participants in both vestibular and cognitive tasks. The performance differences attributed to cognition will be analyzed, and the correlation with vestibular function performance will be integrated to serve as a prescription reference for computer-assisted rehabilitation interventions. Finally, leveraging the advantages of sensor detection technology and computerized feedback, an appropriate dual-task rehabilitation approach for vestibular function and cognition will be developed. Methods: First year, the study will recruit 60 elderly people and integrate the use of inertial sensors and force plates with vestibular and balance tests to establish a vertigo assessment system for the elderly. In the second year, the subjects were divided into two groups: a control group of 25 healthy elderly people, and an experimental group of 25 elderly people who had experienced dizziness and falls in the past two years. Data were collected using a motion analysis system combined with a computerized assisted assessment. The main analysis is whether the experience of dizziness or fall affects the balance, vestibular and cognitive related activities. In the third year, 40 vestibular hypofunction patients will be randomized into either traditional or dual-task group. Both groups will receive 2\~3 times per week for 4 weeks of computerized vestibular interventions with and without dual-task training protocols. Expected achievements: Combining safe stochastic dual-task training and computer-assisted rehabilitation interventions in this 3-year project, the mechanisms of cognition related to vestibular training will be elucidated. The optimal strategy for vestibular rehabilitation can thus be established.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Traditional vestibule rehabilitation training
The intervention for the control group primarily follows conventional rehabilitation methods but incorporates the computerized training system developed in this project.
Traditional vestibule rehabilitation training
* Standing, using a gaze tracking system on a force plate to track a continuously moving target, with alerts when body sway exceeds a certain threshold.
* Standing, wearing an inertial sensor on the head and performing left-right or up-down head movements while maintaining gaze on a target, with a screen providing feedback on head movement speed.
* Standing, controlling body weight distribution on the force plate to reach a target position, with a screen displaying the current center of gravity position.
* Walking, synchronizing head movements with a rhythm or performing up-down head nods, with auditory cues indicating the desired head movement frequency.
* During continuous head rotations, stepping in a regular sequence of forward, backward, left, and right movements.
Dual-task vestibule rehabilitation training
The intervention for the experimental group is based on the intervention for the control group, with additional components based on the findings from the second year of the study. These dual-task exercises are integrated into the training using the computerized training system and provided to the experimental group.
Dual-task vestibule rehabilitation training
* Adding a dual task of digit countdown and recitation to clinical balance training exercises.
* Incorporating a numerical calculation task into interactive screens during clinical balance training, with the participant's responses input by the researchers.
* Introducing upper limb exercises, such as button pressing or arm swinging, during clinical balance training.
* During continuous head rotations, following visual prompts on the display to perform forward, backward, left, and right displacements.
