Brief Summary

The aim is to assess the effects of virtual reality-based intervention on vestibular functions in healthy community dwellers.

Detailed Description

Elderly usually experience an age-related type of vestibular disorder, which involves vertigo, dizziness and poor postural stability. These symptoms seem to contribute to the "geriatric syndrome", which describes a complex symptomatology. It usually has multiple causes and must be considered interdisciplinary. This study will only consider healthy elderly with an expected age-related degeneration of the vestibular system. In terms of restoring vestibular functioning, compensation can be classified into adaptation, substitution and habituation. Adaptation enhances the Vestibulo-ocular reflex, which is equivalent to restoration. Habituation on the other hand, accustoms the affected person to a conflicting situation, in order that the response of the Vestibulo-ocular reflex is avoided. Substitution is distinguished in literature between sensory and behavioral, in which the sensorial substitution transfers the importance given to proprioceptive and visual inputs and the behavioral substitution refers to avoidance strategies e.g. immobilization, increased blink reflex and prevention of head rotations. Slower gait speed may also be a method used by elderly for compensation during a task when the base of support is unstable. Considering recommendation future studies should incorporate examinations of functional gaze stability during typical daily tasks in more familiar settings as opposed to laboratory assessments. Increased head movement may disturb balance and the risk of falling may be raised while walking stairs. As head stability is challenged during stair descent, elderly with age-related visual and vestibular impairment have problems with completing this quotidian task. A way to consider these observations in vestibular rehabilitation is the use of a virtual reality environment, which provides a motivating and pleasant method to train and that includes exercises requiring head turns. Successful use of virtual reality in rehabilitation of vestibular patients has previously been implemented. However, these studies did not particularly to exercise head turns by completing an orientation task.

Study Groups

Exergame

The Senso is a training system (dividat, Schindellegi, Switzerland) for improving physical and cognitive function was used as exergame. With foot pushes participants triggered on a pressure-sensitive plate. The Senso game was projected with a beamer at white wall. To promote head movement during training the direction of the beamer was vertical tilted (± 15°) and horizontal turned (90°) with a remote controlled power panner.

Group Type: EXPERIMENTAL

Exergame

Intervention Type: OTHER

In total, 10 sessions were accomplished including baseline and post intervention measurements. The remaining eight exercise sessions lasted 40 minutes, with an actual training duration of 20 minutes. This resulted in a cumulative total intervention exercise time of 160 minutes.
