Leg-Stand Test Predicts Hip-Fracture Risk in Women

The inability to stand on 1 leg for 10 seconds or to squat down to reach the floor represent strong early predictors of hip fracture and mortality in postmenopausal women, according to a 15-year follow-up study.  

"Squatting down to reach a floor and maintaining balance on 1 foot for a moment are essential functional abilities and very simple to measure. Inability to accomplish either of them demonstrates functional decline with increased risk of mortality and fractures."

At baseline, the women were asked to perform 3 physical tests that were considered to indicate physical capacity — the ability to squat down and touch the floor; the ability to stand on one leg for 10 seconds; and grip strength (with weakest grip indicative of inability to perform the test).

A total of 1587 women (56.9%) showed no functional decline at baseline according to these physical tests and were considered to be the reference group.

Compared with the reference group, the women who did have signs in any of the 3 categories of functional decline had a significantly higher risk for hip fracture.

Risk for mortality was also higher, as was the risk for any fracture among those showing inability to perform any of the 3 tests.

Women who were unable to complete the leg-stand test, however, had the highest risk for hip fracture, with a hazard ratio of 8.4, compared with those who could complete the test.

The second strongest predictor of hip fracture was failure in squatting and touching the floor, with an HR of 5.2, followed by a weak grip strength.
