Simon1* 1 Semmelweis University, Dept. of Anatomy, Histology and Emryology, Hungary The Fourfold Comparative Posturography (Simon et al. 2009) provides basic proofs to assess the clinical state of vertiginous patients by a multiparametric prompt analysis of their body sway. The Posture Evaluation Platform (PEP) was also utilized to follow up changes in posture performance of a healthy young volunteers (aged 19-20 yrs). They spent a complete day and night in a restful room and were called for a posturographic test session every three hours. Between the sessions they were allowed to sit or walk, read, learn, listen to music, but not to get asleep. To reveal fatigue related effect we elaborated 3 independent ways to enhance the difficulty of posture performance, i.e. closed eyes, soft platform surface, 10° tilted plate toes up. A test session consists of the variations given by the provoked conditions: horizontal/tilt plate, hard/soft surface and open/closed eye. To find the most sensitive parameters for sleep deprivation fatigue (SDF) three levels of analysis were applied on the separated lateral and saggital body sway: a) primary time functions; b) comparison among the eight positions and c) self-reflecting analysis based on initial/morning data. The results clearly demonstrate that the differences between a difficult and an easy positions increase by SDF and show significant peaks at evening and dawn hours. The essential outcome of this study is the PEP facility and the comparative posturography can indicate the impact of sleep deprivation fatigue.
