Balance recovery and preventing falls in older adults : When people think about preventing falls, they often imagine advanced technology, medical devices, or specialized therapy. But new research suggests that something much simpler may help people recover their balance after an unexpected slip: a rigid stick shared between two walkers.
In a study published in the Journal of the Royal Society Interface, researchers found that when two people walked side by side while holding a rigid stick, they recovered from sudden balance disturbances faster and more effectively than when they were connected by an elastic band or not connected at all, as per a report.
Testing Balance Recovery in Pairs
To explore how people help each other maintain stability, researchers from France and the United Kingdom studied 12 pairs of volunteers walking on a specialized treadmill, as per a Phys Org report.
The team created unexpected slips and trips by changing the speed of the treadmill belts beneath the participants.
Some pairs walked without any connection. Others were linked by an elastic band or by a rigid stick. Researchers then observed how quickly the walkers recovered their balance after being disturbed.
One Steady Person Can Make a Big Difference
One of the clearest findings came when only one member of a pair experienced a sudden slip. In those situations, the person who remained stable effectively helped the other recover.
Researchers found that recovery was significantly better when only one walker was perturbed compared with situations where both people lost balance at the same time, as per the Phys Org report.
The steady partner essentially acted as an anchor, helping stabilize the person who slipped. According to the researchers, stability improved whenever some form of interaction was present, particularly during slip-related disturbances, as per the Phys Org report.
Why the Stick Worked Better Than the Elastic Band
Not every connection provided the same benefit. The elastic band offered inconsistent assistance because its stretchiness sometimes delayed the transfer of support between partners.
The rigid stick performed much better. Researchers found that the stick reduced peak instability and helped participants recover more quickly. The connected walkers required fewer corrective steps and regained stability faster than participants using the elastic band or no connection at all.
The rigid link allowed forces between the two people to be transmitted immediately, creating a stronger stabilizing effect.

Tiny Signals May Be Doing More Than We Realize
The study also uncovered an unexpected detail about how people coordinate during balance recovery. Researchers analyzed movement patterns to determine how assistance flowed between partners after a slip.
They found that the stable partner influenced the slipping partner through rapid, subtle movements transmitted through the stick, as per the Phys Org report.
Most of this information exchange occurred at around 15 hertz, much faster than the normal rhythm of walking. The findings suggest that touch may provide a fast, almost automatic communication channel that helps people react to balance disturbances before they consciously think about them.
What the Findings Could Mean
The researchers believe the results may be especially relevant for older adults and individuals with walking or balance difficulties. Falls remain a major source of injury among older adults, affecting roughly one in four people aged 65 and older each year, as per the Phys Org report.
The study suggests that firm physical support may provide greater stability than looser forms of contact. It also highlights how a simple rigid connection can help one person assist another during a sudden loss of balance.
