Stabilno posturalna osób p ci eńskiej w wieku 8-22 lat w wietle badań posturograficznych

Posture control is a manifestation of very precise neuro-muscular coordination of all body segments which allows maintaining of body balance in any conditions. Body posture is characterized by the position of the vertical axis of the body in relation to the fulcrum which causes postural instability. Therefore permanent posture control by means of the posture control system is necessary to maintain stability. Body posture as well as its stability undergo modifications along with individual development, that is during growth, development, puberty and aging. The aim of the study was to evaluate postural stability of women aged 8-22 on the basis of posturographic parameters. The efficiency of the balance system was evaluated with the use of a measuring device - Pro-Med posturograph. The testing was carried out in women aged 8-22, divided into three age groups. The posturographic test was performed with open and closed eyes. The stabilogram surface area, oscillation index COP, as well as the length of the stabilogram were analysed. The achieved image of postural stability was diversified. An increase of posturographic parameters was noticed in 8 years old girls and a decrease in 15-16 years old girls and 20-22 years old women. Thus, significantly poorer postural stability in standing position was observed in the 8 year-olds. The role of the frontal and sagittal plane in COP oscillation was also examined. That analysis revealed diversity of WCOP index and normalisation of body sways while maintaining balance in standing position in 20-22 years old women. The posturographic evaluation of postural stability in children, youths and adults (women) revealed in those age groups the dynamics of changes in the process of maintaining balance while standing.
