RESUMO

BACKGROUND: The aim of this multicenter study is to investigate the effect of chronological age and gender in postural control. METHODS: To approach an ecological model, we used a multicenter posturography assessment. We analyzed postural control with surface, mean velocity of center of pressure [CoP] and temporal analysis, with Postural Instability Index [PII] being a more sensitive parameter in postural evaluation. A large sample of 156 age- and gender-matched healthy children recruited in several pediatrics hospitals, participated. RESULTS: Our current results showed a significant decrease of all postural parameters (surface, mean velocity of CoP and PII) with age, and only on stable support condition. Our study additionally described a gender effect in conditions where all sensory inputs are most challenged with a mean velocity of CoP being significantly smaller in girls with respect to boys. CONCLUSION: We concluded that postural control improves with age linked with maturation process. Moreover, this maturation process seems not yet achieved at 16.08 years and still ongoing beyond. Interestingly, our result reported specificities linked with gender effect. Indeed, girls and boys do not proceed in the same way to maintain their postural control. We could make hypothesis that more children maintain their postural control efficiently; with a low energy cost, the more they could allocate attention to learning during childhood.

RESUMO

Vertigo patients frequently complain of emotional and associated cognitive problems, yet currently, there is no satisfactory questionnaire to measure these associated problems. In the present paper, we propose a new internet-based Neuropsychological Vertigo Inventory (NVI; French) that evaluates attention, memory, emotion, space perception, time perception, vision, and motor abilities. The questionnaire was created using four steps: (1) open interviews with patients suffering from vertigo; (2) semi-structured interviews with an analysis grid to quantify and define the various cognitive and emotional problems reported by the patients; (3) a first version of an internet questionnaire tested on 108 vertigo participants; and (4) the selection of subscale items using principal component analyses (PCA). From the development phase, the revised NVI was composed of seven subscales, each with four items (28 items). In the validation phase, Cronbach's alphas were performed on the revised NVI for total and each subscale score, and to test extreme groups validity, the analyses of covariance (ANCOVAs) taking into account age were performed between 108 vertigo and 104 non-vertigo participants. The Cronbach's alphas showed good to satisfactory coefficients for the total and for all subscale scores, demonstrating acceptable reliability. The extreme groups validity analyses (ANCOVAs) were reliable for the total scale and for four subscales. Supplementary analyses showed no effect of hearing difficulties and an inverse age effect for attention and emotion subscales, with reduced problems with increased age in the vertigo participants. The NVI provides a useful new questionnaire to determine cognitive and emotional neuropsychological complaints that are associated with vertigo.
