Does your ability to stand on one leg predict your risk of dying soon?

Some medical doctors say well being checks for older folks ought to embody the “flamingo stability take a look at”, asking folks to face on one leg for 10 seconds – however the connection between stability and well being is unclear

By Clare Wilson

People who find themselves middle-aged or older and might’t stability on one leg for 10 seconds usually tend to die within the subsequent seven years than those that can do it, based on a examine out this week. What’s the rationalization, and will folks practise standing on one leg at house? That is what the science says:

What did the examine examine?

Individuals aged between 51 and 75 had been requested to face on one leg for 10 seconds, with one foot touching the calf of the opposite leg – a bit like a flamingo. Those that couldn’t do that had the next fee of dying through the subsequent seven years than those that accomplished it: 17.5 per cent versus 4.6 per cent. The examine concerned about 1700 folks primarily based in Brazil, most of whom had been white.

Might the findings be associated to different components, reasonably than sick well being?

They might. For example, folks are inclined to worsen at passing this stability take a look at with age, and in case you are older, you usually tend to die. Most of those that had been over 70 had been unable to finish the take a look at. However when the outcomes had been adjusted for components equivalent to age, weight, intercourse and sick well being, they nonetheless confirmed that individuals who couldn’t go the stability take a look at had practically double the dying fee, with an 84 per cent larger danger of dying through the examine interval.

Why would medical doctors ask folks to do that take a look at?

Seeing if folks can stand on one leg has lengthy been used to check stability. Falls are a serious killer of older folks, normally as a result of in the event that they fall over, they might break a hip and want surgical procedure, with some by no means regaining their former mobility. “It may be a spiral,” says David Stensel at Loughborough College, UK. 

So had been the deaths on this examine associated to falls?

It isn’t clear how a lot falls contributed to the deaths of the 123 contributors who died through the examine, if in any respect. The principle causes of dying had been most cancers, coronary heart illness and respiratory ailments, together with covid-19. Falls and restoration from surgical procedure may have contributed to a few of these deaths – for instance, individuals who turn out to be motionless may see their coronary heart illness worsen – however such components weren’t recorded.

How else may stability be linked to dying fee?

The flexibility to face on one leg relies upon not simply on stability, but in addition on leg energy, which is linked to general physique energy and bodily health, says Stensel. Individuals who have coronary heart illness or most cancers, say, are usually much less lively and so would lose leg energy. “It may simply be that means to stability is linked with energy within the legs, which is linked with general energy and health,” he says.

Are the findings stunning?

Earlier analysis has discovered that related checks may give clues about our well being. For example, larger dying charges from coronary heart illness in older folks correlate with gradual strolling pace, in a take a look at the place they had been requested to stroll 6 metres as quick as doable. Total dying charges are additionally linked with folks’s means to face up from sitting on the ground. Maybe extra surprisingly, danger of dying additionally correlates with a poor grip energy, the place somebody is requested to squeeze a testing gadget as arduous as they will, based on a number of research.

Ought to medical doctors begin asking folks to do the take a look at?

The researchers, led by Claudio Gil Araujo at Clinimex train drugs clinic in Rio de Janeiro, Brazil, say of their paper that there could be “potential profit to together with the take a look at as a part of routine bodily examination in middle-aged and older adults”. It’s “easy to include in routine apply because it requires lower than 1 or 2 minutes”, they are saying. However in international locations such because the UK the place well being companies are already stretched, busy household medical doctors could not have time.

How can I enhance my stability?

As a result of it could be general health and physique energy that affects the hyperlink between passing the flamingo stability take a look at and danger of dying, this examine doesn’t present that making an attempt to enhance stability may show you how to reside longer. In older adults, most likely muscle energy is an important health objective, says Stensel. “We’ve got all solely bought a lot time within the day.”

However folks with higher stability are much less prone to fall over, says Uzo Ehiogu, a spokesperson for the Chartered Society of Physiotherapy within the UK. If you wish to enhance your stability, physios advise older folks to do easy workout routines equivalent to strolling in a line as if they’re on a tightrope – or standing on one leg.
