Correlation between vestibular and spatial system in vertical dance performance

Abstract

The aim of this study is to evaluate how the vestibular response intervenes in the adaptation of the body in a different support plan than the usual one (walls). Method The experimental group (EG) was 10 subjects (M=30,8; SD=± 10.00). For each test time, T0 (before training) and T1 (after training), the experimental group underwent with 3 stabilometric evaluations considering only the best. The Cyber SabotsTM stabilometry was used in open/closed eyes (OE/CE) for evaluation the effects of a vertical dance training. Descriptive analysis compares the postural profile variables between experimental and control group (CG) (Rossato et al, 2013). The T-Student analysis was significance in: Wz (.5-2Hz) (CE) (p=.05) and Wz (2-MaxHz) (OE) (p=.006). Oneway ANOVA underlined statistical significance in: Ym (OE-CE/T0-T1) (p=.02), SURFACE (OE-CE/T0-T1) (p=.06), VARVIT (OE-CE/T0-T1) (p=.05), Wz (0-.5Hz) (OE-CE/T0-T1) (p=.002), Wz (2-MaxHz) (OE-CE/T0T1) (p=.00), AVD (OE-CE/T0-T1) (p=.007), TalD (OE-CE/T0-T1) (p=.007). Variables considered were confirmed by post-hoc Bonferroni test. The EG shows a statistical significance on the Wz frequencies (0,52Hz; 2-MaxHz) related to vestibular system in the Fourier Transform (FFT). The significance in open eyes postural profile variables may strengthen the interdependence of visual and vestibular system.
