Abstract

|
The purpose of this study was to quantitatively observe changes in postural stability of double leg support and single limb stance. Thirty-six healthy subjects participated in the study. Postural stability were examined using Dynamic Balance System. Each trial was 25 sec in duration. Each of 6 conditions{double leg support and single limb stance ; eyes open in stable platform, eyes closed in stable platform, eyes open in dynamic platform) evaluated effect of visual, vestibular, proprioceptive system. Center of balance found for displacement to the left along the X axis in double leg support and to the forward on left toe in single limb stance. Sway index was the lowest in double leg support with eyes open in stable platform and the higher in single limb stance with eyes closed in stance platform. We believe that reliable and valid measures should be used to determine the contributing factors of our client’s postural problems so that we can design the most effective treatment possible.
