Single-Leg Balance: Females, Age 80+
Single-leg balance is timed with a 60-second maximum (hands on hips, non-balancing foot raised to the calf). Because most healthy adults under 50 reach the 60-second ceiling, percentile norms are only meaningful for ages 50 and above. Data are from the Canadian Longitudinal Study on Ageing (n=24,969). Where several percentiles equal 60 s, the test cannot distinguish performance at those levels.

Percentile Distribution (s)
| Percentile | Value (s) | Rating |
|---|---|---|
| 5th | 0.5 | Poor |
| 25th | 1.7 | Below average |
| 50th | 3 | Average |
| 75th | 5.4 | Above average |
| 95th | 60 | Excellent |
What these numbers mean for females aged 80+
A score around 3 s is typical (50th percentile) for females in this age group. Scores above about 5.4 s fall near the 75th percentile or higher, indicating above-average performance. Scores below about 1.7 s fall near the 25th percentile, about 75% of the reference population scored higher.
This test has a 60-second maximum. Most healthy adults under 50 can hold a single-leg stance for the full 60 seconds, so this metric is most informative for ages 50 and above. Where multiple percentiles equal 60 s, the test cannot distinguish performance at those levels.
Percentiles show how common a value is, not whether it is healthy.
