Abstract: ObjectiveTo explore the normal limits and influential factors of the static balance function of normal adults.Methods445 healthy volunteers (16～74 years old, 205 of male and 240 of female) were detected by static posturography while they were respectively in seat, double feet standing with eyes opened and closed, and single foot standing only with eyes opened. The normal reference value of all indicatrix were calculated.ResultsThe normal reference value of static balance function of normal adults, male, female and all age groups were calculated.ConclusionThe detection of static posturography can evaluate human balance function objectively, quantitatively and exactly. The determination of the normal limits of balance function will conduce to evaluate balance disturbance and diagnose correlated diseases.

Key words: balance function, normal reference value, static posturography
