Intersession Reliability of Posturographic Measurement and Impact of Somatometric chracteristics on Balance Control Aging
Abstract
Older adults show increased amounts of postural sway in both medial-lateral (M/L) and anterior-posterior (A/P) directions. Postural sway increases progressively with aging and ultimately may lead to falls.
Mechanisms contributing to age related increases in postural sway are supposed and often discussed but, nevertheless, remain unproved. Greater values of body sway indicator, in this case Center of Pressure (COP) displacements, combined with somatometric characteristics and Berg Balance Scale testing, show tendencies to fall (in A/P and M/L direction) as well as possible impact of age-related changes in somatometric characteristics on increasing postural sway.
In present paper authors suggest that age-related changes in somatometric characteristics are related to age-worsened postural sway while maintaining balance in quiet stance. An important phenomenon for our study is represented by assessing an intersession reliability, which emerges from our previous study.
