ABSTRACT
Twenty children, aged 10 to 12 years with attention-deficit/hyperactivity disorder (ADHD), were selected to study the effect of vestibular stimulation on auditory perception and sensitivity using the Integrated Visual and Auditory Continuous Performance Test (IVA CPT; a neuropsychological test that is applied in occupational therapy clinics). The present study examined children based on the criteria of the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, text revision. After obtaining guardian and parental consent, the children were enrolled in the study and randomly matched according to age across intervention and control groups. The IVA CPT was applied as a pre-test. The children in the intervention group then received vestibular stimulation during therapy sessions twice per week for 10 weeks. The IVA CPT assessment (post-test) was then applied in both groups. The mean pre- and post-test scores were compared across groups. The statistical analyses revealed a significant difference in improvement in auditory comprehension. In conclusion, the present findings suggest that vestibular training is a reliable and powerful treatment option for ADHD, especially when combined with other training. Stimulating the sense of balance highlights the important interaction between inhibition and cognition...

BACKGROUND AND OBJECTIVES: The parameters of vestibulo-ocular reflex (VOR) are believed to indicate the quantitative value of vestibular function and the differences in them are related to the susceptibility of motion sickness. The purpose of this study was to investigate the effects of repetitive multiaxial 3-dimensional rotation training on VOR parameters. MATERIALS AND METHODS: Fifteen healthy volunteers were randomly assigned to 3 different groups according to the mode of exercise training. Aerotrim exercise was done as a method of repetitive multiaxial 3-dimensional rotation training. The changes in VOR parameters after 9 weeks of exercise training in Aerotrim training group were compared with that of other groups. RESULTS: While the values of VOR gain in Aerotrim training group after 9 weeks of exercise training were significantly lower than baseline values at rotation frequencies of 0.01, 0.04, 0.08, 0.16, and 0.32 Hz, values of VOR gain in other groups showed no difference between before and after exercise training. In all groups, there were no significant differences in VOR phase and symmetry values between before and after exercise training. CONCLUSION: This study showed that VOR parameters changed after 9 weeks of repetitive multiaxial 3-dimensional rotation training, and vestibular habituation might eventually occur. Since vestibular habituation is known to contribute to mitigating the frequency and the degree of motion sickness, we suggest that repetitive multiaxial 3-dimensional rotation training can be used as the countermeasure for student pilots or astronauts, who are often exposed to unusual motion and positional status in actual 3-dimensional space.

Benign paroxysmal positional vertigo is the most common vestibular disorder and it has a significant impact in health-related quality of life. The disease is probably caused by the accumulation of lithiasis material from the otolithic membrane of the utricle. Patients experience multiple short crises of vertigo lasting seconds when they lay or turn in bed. There are several clinical variants affecting posterior, horizontal or anterior canal and in some cases vestibular lithiasis can occur in two canals simultaneously. The diagnosis is performed by video-oculographic recording of positional nystagmus during positional testing to identify the canal affected. There are specific treatment maneuvers for each clinical variant, which are highly effective at short term
El vértigo posicional paroxístico benigno es el trastorno vestibular más frecuente y tiene un impacto significativo sobre la calidad de vida relacionada con la salud. La enfermedad se origina probablemente por la acumulación de un material litiásico procedente de la membrana otolítica del utrículo. Los pacientes sufren múltiples crisis de vértigo cortas que duran segundos cuando se acuestan o se dan la vuelta en la cama. Existen varias formas clínicas que pueden afectar los conductos posterior, horizontal o anterior y que en algunos casos afectan dos conductos simultáneamente. El diagnóstico se realiza mediante el registro videooculográfico del nistagmo posicional al realizar las pruebas posicionales para localizar el conducto afectado. Existen maniobras terapeúticas específicas para cada variante clínica, las cuales presentan una elevada efectividad a corto plazo
