Frequency spectral characteristics of standing balance in children and young adults

摘要: Abstract Past research has shown that spectral frequency characteristics of a balance control system may be useful for early detection minor changes in the system. Since there is lack information regarding spectrum children’s system, this study was undertaken to investigate and compare standing between children young adults under altered sensory environments. Seventeen (9 females, 8 males, mean age 7.8±0.9 years) same number female male (mean 21.1±1.3 were tested six conditions. These conditions created by crossing three levels visual factor (open eye, closed sway-referenced vision) with two somatosensory (fixed foot support, compliant support). The median frequencies shear forces anterior–posterior (A/P) medial–lateral (M/L) directions used as dependent variables. results showed had higher A/P force than difference not affected factor. M/L direction different groups. rate body mass vibration implies have fully developed ankle strategy maintaining balance, but nonetheless efficiency using vision their reference balance.
