[Quantified research of measuring postural balance by posturography using inclinometer technique].

OBJECTIVE: To gain the normal values of posturography using inclinometer technique in people, to gain the normal values of posturography using inclinometer technique in people. METHOD: The messages of postural average sway angular velocity (omega) obtained by posturography using inclinometer technique in four various conditions were measured in 167 normal subjects who were grouped by age. RESULT: The normal omega values show that there is no correlation between postural balance with gender, but postural balance is related with age. The postural stability is at its best at the age of 20 to 60 years. The direction of postural sway has a large inter-individual variability, but no significant inclined direction is found. CONCLUSION: The results of individual tests should be compared with match-aged normative data in order to determine abnormal postural balance function. We measured many subjects and grouped by ages in detail. Therefore, the result can be taken as normative data of the measuring system. The omega value of standing on global-ottomed platform with eye closed could distinguish abnormal balance function of vestibo-spinal system accurately.
