2BALANCE: Cognitive-motor Dual-tasking in Persons With Vestibular Disorders

2019-10-21 12:45:39 | BioPortfolio


The overall aim of this study is to elucidate the impact of a vestibular dysfunction on the cognitive and motor performance by means of an extensive test protocol, evaluating the vestibular, cognitive and motor function using single as well as dual-task paradigms.


The test protocol consists of five cognitive tasks, all assessing a different cognitive domain: executive function, working memory, processing speed, and visuospatial abilities (mental rotation and visuospatial memory). These cognitive tasks will be performed separately (in single task condition, while seated), as well as while performing different motor tasks (in dual-task condition). These motor tasks will also be performed in single task condition (without performing the cognitive tasks).

The study consists of the establishment of normative age-related data for the single as well as dual-task protocol in healthy adults, age ranging from 18 to 65 years old (objective 1). Subsequently, the test protocol will be validated in persons with bilateral vestibulopathy (objective 2). Finally, a cross-sectional study in persons with unilateral vestibular impairment will take place, and the results on the single as well as dual-task components will be compared to normative data, as well as to persons with bilateral vestibulopathy (objective 3).

Medical and Biotech [MESH] Definitions

Pathological processes of the VESTIBULAR LABYRINTH which contains part of the balancing apparatus. Patients with vestibular diseases show instability and are at risk of frequent falls.

The vestibular part of the 8th cranial nerve (VESTIBULOCOCHLEAR NERVE). The vestibular nerve fibers arise from neurons of Scarpa's ganglion and project peripherally to vestibular hair cells and centrally to the VESTIBULAR NUCLEI of the BRAIN STEM. These fibers mediate the sense of balance and head position.

Vestibular nucleus lying immediately superior to the inferior vestibular nucleus and composed of large multipolar nerve cells. Its upper end becomes continuous with the superior vestibular nucleus. (From Dorland, 28th ed)

Pathological processes of the VESTIBULOCOCHLEAR NERVE, including the branches of COCHLEAR NERVE and VESTIBULAR NERVE. Common examples are VESTIBULAR NEURITIS, cochlear neuritis, and ACOUSTIC NEUROMA. Clinical signs are varying degree of HEARING LOSS; VERTIGO; and TINNITUS.

The 8th cranial nerve. The vestibulocochlear nerve has a cochlear part (COCHLEAR NERVE) which is concerned with hearing and a vestibular part (VESTIBULAR NERVE) which mediates the sense of balance and head position. The fibers of the cochlear nerve originate from neurons of the SPIRAL GANGLION and project to the cochlear nuclei (COCHLEAR NUCLEUS). The fibers of the vestibular nerve arise from neurons of Scarpa's ganglion and project to the VESTIBULAR NUCLEI.
