Effects of Galvanic Vestibular Stimulation on Statokinesigrams of the Elderly

چکیده
Special suits have been designed to simulate the physical functions of the elderly. However, it has been suggested that these suits do not simulate the postural instability that is actually observed in elderly subjects. We consider that postural instability in the elderly is caused by anomalous signals in the vestibules. In this study, we have verified this hypothesis by using galvanic vestibular stimulation (GVS) that can mask regular signals until they reach the vestibular nuclei. In conclusion, we could simulate the deterioration in equilibrium function with advancing age to a certain extent. We have also revealed that postural instability in the elderly may be improved by the presence of visual information.

Noisy galvanic vestibular stimulation induces a sustained improvement in body balance in elderly adults
Vestibular dysfunction causes postural instability, which is prevalent in the elderly. We previously showed that an imperceptible level of noisy galvanic vestibular stimulation (nGVS) can improve postural stability in patients with bilateral vestibulopathy during the stimulus, presumably by enhancing vestibular information processing. In this study, we investigated the after-effects of an imper...

Introduction: Although vestibular rehabilitation therapy (VRT) methods are relatively popular in treating patients with body balance deficits of vestibular origin, only limited studies have been conducted into customized exercises for unilateral vestibular hypofunction (UVH). Furthermore, very little evidence is available on the outcomes of VRT in the elderly population with chronic UVH. Materi...

Objectives: Among the most important problems of autistic children are the behavioral disorders due to sensory processing deficiency, which are typically reflected in behaviors such as impulsivity, attention and concentration disorders, undesirable emotional reactions, sensory seeking in the form of stereotype behaviors, self-injury and self-stimulating. The present study aimed at exploring the...
