Abstract
Postural stability was measured in 100 healthy people by a quantitative, computer calculated Romberg''s test. The persons were aged 20-69 yr, and a table of normal ranges is provided. Older men had higher sway figures than young men; this was not significant in the group of women. Reproducibility of the method was also studied in 10 healthy people. Sway was measured twice a day during 5 consecutive days of work. No significant alterations in the sway measurement were found. The individual variation coefficients ranged from 11 to 29% (mean value: 18%). The quantitative Romberg''s test is a reasonable way of measuring postural stability.
