Status Enrolling by invitation

Clinical Trial Summary

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. The investigators will compare the movement abilities among older adults with different cognitive level, and further establish an assessment module that can evaluate participants' dual-task performance in both vestibular and cognitive tasks. 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.

Clinical Trial Description

Dizziness is one of the most common complaints among older adults and often a concern within healthcare systems. It leads to distressing sensations, reduced mobility, and decreased quality of life. Dizziness is also closely associated with falls, which are a major cause of comorbidities and mortality in older adults. During clinical rehabilitation training, it has been observed that some elderly patients with vestibular dizziness often experience difficulties with speech clarity, lack of attention, poor direction control, or easy forgetfulness of rehabilitation training content. Similar observations have been made by scholars who interacted with dizzy patients, noting difficulties in maintaining attention, deficits in attention and spatial memory, speech expression impairments, and impacts on spatial memory, fluency of speech, thinking abilities, calculation impairments, and other forms of numerical cognition. Clinical studies have already noted the association between vestibular dysfunction and cognitive impairment. However, there is limited research that can clarify the intricacies and complexities of this issue. Currently, there is scarce knowledge regarding the relationship between the vestibular system and specific cognitive aspects, as well as its correlation with balance deficits.

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. ;
